Description

  The present invention relates to a portable electronic device including a reader for non-contact IC, an authentication method thereof, a container for the device, a communication system, a control program, and a recording medium on which the program is recorded. In particular, the present invention relates to a portable electronic device that performs authentication using a non-contact IC reader.

  As authentication in portable electronic devices such as mobile phones and PDAs (Personal Digital Assistants), authentication using passwords and authentication using biometric information such as fingerprint information are known. Recently, authentication using incoming information such as incoming number, incoming number of calls, number of calls, etc., which is used in a lock function called “remote dial lock” is known.

  However, in the case of password authentication, short passwords are easily guessed by others and are easily specified by others by repeated input. On the other hand, a long password is easy for the user to forget and it is a burden for the user to keep memorizing it.

  Further, in the case of authentication using biometric information, it is extremely difficult to impersonate another person, so that a very high security level can be maintained. However, in this case, it is necessary to newly provide detection means for detecting biological information.

  Also, in the case of authentication using incoming information, if the user is in an area where radio waves from the base station do not reach or is in a state where transmission of radio waves is stopped, the incoming call cannot be made and authentication cannot be performed.

  Recently, mobile phones equipped with non-contact ICs have begun to be marketed. If this mobile phone is used, the ticket gate processing and the settlement processing can be performed instantaneously, so further spread is expected in the future. In the near future, it is expected that mobile phones equipped with reader / writers for non-contact ICs that can read information from external non-contact ICs will be marketed. Therefore, it is conceivable to authenticate the portable electronic device using a non-contact IC.

  Examples of authentication using a conventional non-contact IC include Patent Documents 1 and 2 below. In the security device for information recording media described in Patent Document 1, a non-contact IC card chip is embedded in a CD-ROM, an RF reader / writer is attached to a CD device, and stored in a memory in the non-contact IC card chip. The security function of the CD device is improved by verifying the password.

In addition, in the authentication system described in Patent Document 2, when a customer applies a transaction from an ATM using a bank card issued for each customer, authentication using a secure chip as an authentication tool is performed. Is going. This secure chip is an authentication tool different from a bank card, and is attached to an article having a permanent property. When the host computer determines that it is necessary to perform authentication separate from authentication using the bank card, the host computer instructs the ATM to access the secure chip. ATM accesses a secure chip via a non-contact data carrier system in order to perform authentication based on SC identification information stored in the secure chip and individually assigned to each secure chip.
JP 2000-57296 A (published February 25, 2000) JP 2002-318093 A (released on October 31, 2002)

  However, in the security device for information recording media described in Patent Document 1, it is necessary to hold the password stored in the memory in the non-contact type IC card chip on the RF reader / writer side. Reading from a CD-ROM in which a contact IC card chip is embedded makes it unclear whether the CD-ROM is a genuine product. For this reason, the password needs to be recorded in advance when the security device is manufactured, or read from another information recording medium.

  On the other hand, in the authentication described in Patent Document 2, the secure chip is issued individually for each customer as in the case of the bank card (paragraph [0016] of the same document). For this reason, when performing authentication using a non-contact IC (secure chip) according to the description of Patent Document 2 on a mobile phone equipped with a reader / writer for non-contact IC, the user of the mobile phone creates a secure chip, Alternatively, it is necessary for a mobile phone manufacturer or a mobile phone service provider to create a secure chip for each mobile phone and issue it to the user, resulting in a significant increase in cost and labor.

  The present invention has been made in view of the above-described problems, and its purpose is to use a non-contact IC reader, and without burden and burden on users, manufacturers, service providers, etc. An object of the present invention is to provide a portable electronic device that can perform authentication using a contact IC.

  In order to solve the above problems, a portable electronic device according to the present invention is a portable electronic device including a non-contact IC reader, and is stored in a storage means for storing information and an external non-contact IC. The identification information is received via the contactless IC reader, and the received identification information is stored in the storage means, thereby registering the identification information, and the identification information stored in the external contactless IC. Authentication means for performing authentication based on the identification information of the non-contact IC by comparing the received identification information with the identification information registered by the registration means. It is a feature.

  Here, as the identification information, it is desirable to use an ID number uniquely assigned to each non-contact IC. However, if the information is fixed to the non-contact IC and can identify the non-contact IC, Arbitrary information can be used. For example, the manufacturer information alone is unlikely to be used as identification information because it is unlikely that a non-contact IC can be identified. On the other hand, since information that combines manufacturer information and date of manufacture increases the possibility of identifying a non-contact IC, it can be used as identification information.

  According to the above configuration, the registration unit registers the identification information by receiving the identification information stored in the external non-contact IC and storing it in the storage unit. And when authenticating, the authentication means collates the identification information stored in the external non-contact IC and the identification information registered by the registration means. Therefore, since the portable electronic device according to the present invention can register the identification information of the non-contact IC used for authentication, the existing non-contact IC can be used, and there is no need to newly create the non-contact IC. Therefore, it is possible to perform reliable authentication using a non-contact IC without burdening a user, a manufacturer, a service provider, or the like to create a new non-contact IC.

  In the portable electronic device according to the present invention, it is preferable that the registration unit registers a plurality of the identification information by causing the storage unit to store the identification information stored in the plurality of non-contact ICs.

  Further, the authentication unit may perform the authentication by checking whether the received identification information matches any of a plurality of identification information registered by the registration unit. In this case, the user does not have to carry all the registered non-contact ICs with the portable electronic device, and the convenience for the user is improved.

  The authentication unit receives the identification information stored in the plurality of non-contact ICs via the non-contact IC reader, and the received plurality of identification information includes a plurality of identification information registered by the registration unit. The above authentication may be performed by checking whether or not each matches. In this case, since it is necessary to collate all registered non-contact ICs, security can be improved.

  The authentication unit receives the identification information stored in the plurality of non-contact ICs via the non-contact IC reader, and the received plurality of identification information includes a plurality of identification information registered by the registration unit. And the authentication may be performed by checking whether the order of the received plurality of identification information matches the order of the plurality of registered identification information. In this case, since it is necessary to collate all registered non-contact ICs in order, security can be further improved.

  The portable electronic device according to the present invention further includes input means for receiving input of information from a user, the storage means stores a password, and the authentication means identifies the non-contact IC. Authentication based on information by non-contact IC authenticating means for authenticating by information, and by receiving the personal identification number from the user via the input means and comparing the received personal identification number with the personal identification number stored in the storage means It is preferable to include a personal identification number authenticating unit for performing the authentication, an authentication switching unit for switching between the non-contact IC authenticating unit and the personal identification number authenticating unit. In this case, since authentication using the identification number of the non-contact IC and authentication using the personal identification number can be switched, authentication using the personal identification number is a last resort when the user does not hold the registered non-contact IC. The convenience of the user is improved. As described above, since the personal identification number is the last means of authentication, it is desirable that the number of digits is large in view of the above-mentioned conventional problems.

  The portable electronic device according to the present invention preferably further includes a lock unit that locks the device itself, and a lock release unit that releases the lock when the authentication unit authenticates. In this case, authentication by the non-contact IC of the present invention can be used for unlocking, and the security of the portable electronic device can be improved.

  It should be noted that various objects can be considered for locking, and can be locked separately, or can be locked as a whole. Examples of objects to be locked include key operation, access to address book, access to sent or received e-mail, access to captured images on camera-equipped mobile phones, and contactless IC readers For example, access to a storage unit of a non-contact IC reader when using the electronic money.

  By the way, even if the portable electronic device has a function of locking, security cannot be maintained if the portable electronic device is lost or stolen without locking. Therefore, the lock unit may include an automatic lock unit that automatically locks the device itself when the authentication unit does not perform authentication for a predetermined period. Thus, even if the portable electronic device is lost or stolen without being locked, it can be automatically locked after a predetermined period.

  Furthermore, it is preferable that the automatic lock means performs the lock automatically when the authentication means does not authenticate for a predetermined period and the authentication means performs the authentication and does not authenticate. In this case, since the portable electronic device requires the user to read the non-contact IC for authentication before automatically locking, the user can operate the portable electronic device while operating the portable electronic device. It is possible to prevent the lock from occurring without knowing.

  In addition, the lock unit may include an automatic lock unit that automatically locks the device itself when the authentication unit is authenticated at a predetermined time and authentication is not possible. Thus, even when the portable electronic device is lost or stolen without being locked, it can be automatically locked after a predetermined time has elapsed.

  Note that the present invention is preferably applied to a mobile phone that stores personal information such as a telephone directory and e-mail transmission / reception data and performs electronic payment using a non-contact IC.

  A container for a portable electronic device according to the present invention is a container for accommodating a portable electronic device including a reader for non-contact IC, and when the portable electronic device is accommodated, A non-contact IC having identification information is provided at a communicable position. In addition, the communication system according to the present invention includes a portable electronic device including an automatic lock unit that automatically locks the device itself if the authentication unit cannot perform authentication at a predetermined time. It is the structure provided with the said container for portable electronic devices.

  In the case of a portable electronic device, when the device is not used, such as at midnight, it is placed in a container and charged. Therefore, a non-contact IC is provided in the container, and can be automatically locked when authentication by the non-contact IC cannot be performed at a predetermined time. In general, since the user does not carry the container, the user can securely lock the portable electronic device even if it is lost or stolen while carrying the portable electronic device.

  An authentication method for a portable electronic device according to the present invention is an authentication method for a portable electronic device provided with a reader for non-contact IC, and the identification information stored in an external non-contact IC is used for the non-contact IC. A registration step for receiving and registering via a reader, and identification information stored in an external non-contact IC received via the non-contact IC reader, and the received identification information and registered in the registration step And an authentication step of performing authentication using the identification information of the non-contact IC by collating with the identification information.

  According to the above method, in the registration step, the identification information stored in the external non-contact IC is received and registered. When authentication is performed, the identification information stored in the external non-contact IC is compared with the registered identification information in the authentication step. Therefore, since the identification information of the non-contact IC used for authentication can be registered, the existing non-contact IC can be used, and there is no need to newly create the non-contact IC. Therefore, it is possible to perform reliable authentication using a non-contact IC without burdening a user, a manufacturer, a service provider, or the like to create a new non-contact IC.

  Note that the registration means and the authentication means in the portable electronic device can be executed on a computer by a control program. Furthermore, the control program can be executed on any computer by storing the control program in a computer-readable recording medium.

  As described above, since the portable electronic device according to the present invention can register the identification information of the non-contact IC used for authentication, the existing non-contact IC can be used, and the user, manufacturer, service provider, etc. can be used. Thus, there is an effect that reliable authentication using the non-contact IC can be performed without taking the trouble and burden of newly creating the non-contact IC.

In this case, since it is necessary to collate all registered non-contact ICs in order, security can be further improved.

  As another example of the authentication condition, whether or not the plurality of identification information read from the plurality of contactless IC cards 50 matches a part of the plurality of identification information stored in the lock-related record 70. And determining whether the reading order of the plurality of identification information matches a part of the storage order of the plurality of identification information.

  According to the above configuration, the contactless IC information registration unit 60 registers the ID number by receiving the ID number stored in the contactless IC card 50 and storing it in the lock-related record 70 of the storage unit 27. Yes. When the mobile phone 1 is locked by the lock control unit 61 and the user operates the operation unit 26 to give an unlock instruction, the lock release unit 62 stores in the non-contact IC card 50. The authentication is performed by comparing the ID number that is stored with the ID number stored in the lock-related record 70, and if the authentication is successful, the lock is released. Therefore, since the mobile phone 1 of the present embodiment can register the ID number of the non-contact IC used for authentication, the existing non-contact IC can be used, and there is no need to newly create a non-contact IC. Therefore, it is possible to perform reliable authentication using a non-contact IC without burdening a user, a manufacturer, a service provider, or the like to create a new non-contact IC.

  Next, the detailed configuration of the lock-related record 70 in the storage unit 27 and the processing operation in the control unit 31 will be described with reference to FIGS. FIG. 7 shows the configuration of the lock related record 70 in the storage unit 27. As shown in the figure, the lock-related record 70 includes, in order, the number of registrations of non-contact ICs, the maximum registration value of non-contact ICs, the release conditions when registering multiple IDs, the password number, and the ID numbers of one or more non-contact ICs. It is the composition which includes. The lock-related record 70 is preferably stored in a nonvolatile memory so that the lock-related record 70 is retained even when the power of the mobile phone 1 is turned off.

  The number of registered non-contact ICs indicates the number of ID numbers of registered non-contact ICs. When the ID number of the non-contact IC is not registered, “0” is stored in the registration number of the non-contact IC. Thereby, it is possible to determine whether or not the ID number of the non-contact IC is unregistered by referring to the registration number of the non-contact IC.

  The non-contact IC registration maximum value indicates the maximum number of non-contact IC registrations. This value may be fixed or may be set by the user. The storage area of the lock-related record 70 to be secured in the storage unit 27 can be determined based on the registered maximum value of the noncontact IC.

  The release conditions at the time of registering multiple IDs indicate lock release conditions (authentication conditions) when ID numbers of a plurality of non-contact ICs are registered, and numerical values corresponding to the respective lock release conditions are stored. Thereby, the user can set the unlocking condition.

  For example, when the above-described unlocking condition is that the identification information read from the non-contact IC card 50 matches any one of a plurality of identification information stored in the lock-related record 70, a plurality of IDs are registered. “0” is stored in the release condition. Further, when the above-described unlocking condition is that the plurality of pieces of identification information read from the plurality of non-contact IC cards 50 match all of the plurality of pieces of identification information stored in the lock-related record 70, a plurality of IDs “1” is stored in the cancellation condition at the time of registration. Further, the above-described unlocking condition is that the plurality of identification information read from the plurality of non-contact IC cards 50 matches all of the plurality of identification information stored in the lock-related record 70 and also matches the order. In this case, “2” is stored in the cancellation condition when registering multiple IDs.

  The password is used for unlocking with the password. As described above, in the present embodiment, the password is used as the last unlocking means when unlocking by the non-contact IC card 50 is impossible, so that a number with a long number of digits is stored. become. The personal identification number may be set in a default state or may be set by the user.

  The ID number of the non-contact IC is an ID number read from the non-contact IC card 50. For example, “Suica (trademark)”, which is an IC card used in the ticket gate system of East Japan Railway Company (JR East), uses a 17-digit card ID.

  FIG. 8 shows a flow of registration processing of key non-contact IC information (non-contact IC ID number). This process is performed when the mobile phone 1 is purchased or when the user performs an operation for executing the registration process.

  First, the personal identification number is confirmed and / or registered (step S10 (hereinafter may be abbreviated as “S10”. The same applies to other steps)). Specifically, the non-contact IC information registration unit 60 displays the code number on the main screen 10 by reading the code number stored in advance in the lock related record 70 and transmitting it to the main display unit 28. Further, the non-contact IC information registration unit 60 acquires a new password from the operation unit 26 when the user operates the operation unit 26, and stores the acquired password in the lock-related record 70.

  Next, the non-contact IC information registration unit 60 controls the main display unit 28 or the audio output unit 24 to display to instruct the user to place the non-contact IC card 50 to be registered in the vicinity of the reader / writer 12. Or output audio. Next, the non-contact IC information registration unit 60 controls the reader / writer 12 to read from the non-contact IC card 50 the ID number of the non-contact IC that is a key for unlocking (S11).

  Next, the non-contact IC information registration unit 60 stores and registers the read ID number of the non-contact IC in the lock-related record 70, and increases the registration number of the non-contact IC in the lock-related record 70 by 1 (S12). ). Next, the non-contact IC information registration unit 60 determines whether or not the increased number of non-contact IC registrations matches the maximum number of non-contact IC registrations in the lock-related record 70 (S13). If they match (YES in S13), the ID number of the non-contact IC cannot be registered any more and the non-contact IC information registration process is terminated. On the other hand, if they do not match (NO in S13), the process proceeds to the next step S14.

  Next, the non-contact IC information registration unit 60 controls the main display unit 28 or the audio output unit 24 to inquire the user whether or not to perform the next registration (S14). If the user operates operation unit 26 and does not perform the next registration (NO in S14), the non-contact IC information registration process is terminated. On the other hand, when the next registration is performed (YES in S14), the process proceeds to the next step S15.

  Next, the non-contact IC information registration unit 60 refers to the number of non-contact IC registrations in the lock-related record 70 and determines whether or not the next registration is the second registration (S15). This is because, as described above, when the ID numbers of a plurality of non-contact ICs are registered, various lock release conditions can be selected. If it is not the second registration (NO in S15), the process returns to step S11 and the above operation is repeated. On the other hand, if it is the second registration (YES in S15), the process proceeds to step S16.

  Next, the non-contact IC information registration unit 60 controls the main display unit 28 or the audio output unit 24 to notify the user of the unlocking condition “the identification information read from the non-contact IC card 50 is locked. “Matched with any one of a plurality of identification information stored in the record 70”, “a plurality of identification information read from a plurality of non-contact IC cards 50 is a plurality of identifications stored in the lock related record 70” Match all of the information ”, and“ the plurality of identification information read from the plurality of non-contact IC cards 50 matches all of the plurality of identification information stored in the lock-related record 70, and the order is also It is instructed to select from “matching” (S16). Then, the number corresponding to the unlock condition selected by the user by operating the operation unit 26 is stored in the cancel condition when registering a plurality of IDs in the lock related record 70. Thereafter, the process returns to step S11, and the registration of the ID number of the non-contact IC is repeated as many times as the user desires.

  FIG. 9 shows the flow of the lock process. As shown in the figure, first, the user operates the operation unit 26 to instruct the mobile phone 1 to perform locking (S20). At this time, the lock control unit 61 refers to the lock-related record 70 to determine whether or not the number of registered non-contact ICs is other than 0, that is, whether or not the ID number of the non-contact IC is registered. (S21).

  If the registration number is other than 0, that is, if the ID number of the non-contact IC has already been registered (YES in S21), the process proceeds to step S22. On the other hand, when the number of registrations is 0, that is, when the ID number of the non-contact IC is not registered (NO in S21), the non-contact IC information registration unit 60 performs registration processing of the non-contact IC information (FIG. 8 to execute S10 to S16). Thereafter, the process proceeds to step S22.

  Next, the operation mode of the apparatus (mobile phone 1) is set to the locked state (S22), and then the lock process is terminated. At this time, as described above, various functions of the mobile phone 1 can be individually or collectively locked.

  FIG. 10 shows the flow of the unlocking process. As shown in the figure, first, when the user operates the operation unit 26 to instruct the mobile phone 1 to execute unlocking, the unlocking unit 62 controls the main display unit 28 to unlock the main screen 10. A menu is displayed (S30). This lock release menu includes an image for selecting whether to use the authentication by the password or the authentication by the ID number of the non-contact IC.

  Next, the lock release unit 62 determines which of the authentication by the personal identification number and the authentication by the ID number of the non-contact IC is selected by the user operating the operation unit 26 (S31). When the authentication by the personal identification number is selected, the lock release unit 62 controls the main display unit 28 or the voice output unit 24 to request the user to input the personal identification number by the display screen or voice. When the user operates the operation unit 26 and a password is input (S32), the lock release unit 62 determines whether or not the input password matches the password stored in the lock-related record 70. Is determined (S33).

  If the passwords match (YES in S33), the unlocking unit 62 instructs the lock control unit 61 to unlock the device (S40). Thereafter, the unlocking process is terminated.

  On the other hand, if the code numbers do not match (NO in S33), the lock release unit 62 controls the main display unit 28 to display on the main screen 10 that the lock release has failed (S34). Then, it returns to step S32 and repeats the authentication process by a PIN code.

  On the other hand, when the authentication based on the ID number of the non-contact IC is selected in step S31, the lock release unit 62 controls the main display unit 28 or the audio output unit 24 to be a non-contact IC that is a key for unlocking. The user is instructed to place the card 50 near the reader / writer 12. Next, the lock release unit 62 controls the reader / writer 12 to read the ID number of the non-contact IC from the non-contact IC card 50 (S35).

  Next, using the read ID number of the non-contact IC, it is determined whether or not the release condition selected in step S16 is satisfied (S36). If the release condition is met (YES in S36), the lock release unit 62 instructs the lock control unit 61 to release the lock of the device (S40). Thereafter, the unlocking process is terminated.

  On the other hand, if the release condition is not met (NO in S36), it is determined whether or not reading of the ID number of the non-contact IC is completed by the number of registrations of the non-contact IC stored in the lock related record 70. (S37). This determination processing is for the case where authentication is performed using a plurality of registered non-contact IC ID numbers. If the reading has not been completed (NO in S37), it is determined that there is still an ID number of a non-contact IC to be read, and the process returns to step S35.

  On the other hand, when the reading is completed (YES in S37), the unlocking unit 62 controls the main display unit 28 to display on the main screen 10 that the unlocking has failed (S38). . Next, as in step S30, an unlock menu is displayed on the main screen 10 (S39), and then the process returns to step S31. This is because if the authentication by the ID number of the non-contact IC fails, the user may desire to switch to the authentication by the password.

  In addition, when the mismatch of the personal identification number is repeated a predetermined number of times in step S33, or when the mismatch of the release condition is repeated a predetermined number of times in step S36, the authorized user is not operating. It is desirable to make it impossible to release the lock for a predetermined period of time, or to disable the lock release by the user and enable the service center to release the lock.

[Embodiment 2]
Next, another embodiment of the present invention will be described with reference to FIGS. The cellular phone 1 of the present embodiment is different from the cellular phone 1 shown in FIGS. 1 to 10 in the configuration of the control unit and the data stored in the storage unit, and the other configurations are the same. In addition, the same code | symbol is attached | subjected to the structure and process which have the function similar to the structure and process demonstrated in the said embodiment, and the description is abbreviate | omitted.

  The mobile phone 1 according to the present embodiment automatically locks when authentication is not performed during a predetermined period. As a result, even if the mobile phone 1 is lost or stolen without performing the lock operation, the lock is automatically locked so that a third party cannot use the predetermined function of the mobile phone 1. It can be carried out.

  FIG. 11 shows a schematic configuration of the control unit 31 and the storage unit 27 in the mobile phone 1 of the present embodiment. Compared with the control unit 31 shown in FIG. 1, the control unit 31 of the present embodiment includes an automatic lock cycle registration unit 63, an automatic lock setting unit 64, an automatic lock check unit (automatic lock means) 65, and an automatic lock postponement unit. The difference is that 66 is newly added, and other configurations are the same. In the present embodiment, the newly added automatic lock setting unit 64 and automatic lock check unit 65 use the calendar clock 32. Further, the storage unit 27 of the present embodiment is different from the storage unit 27 shown in FIG. 1 in that an automatic lock related record 71 is newly added, and the other configurations are the same.

  The calendar clock 32 represents the current date and time, and continues to operate with a dedicated battery even when the main power supply of the mobile phone 1 is turned off. The date and time of the calendar clock 32 may be set by the user operating the operation unit 26, or may be set automatically by obtaining accurate time information from a time server.

  The automatic lock cycle registration unit 63 acquires the cycle in which the automatic lock check unit 65 performs the automatic lock check process from the user via the operation unit 26, and stores the acquired cycle in the automatic lock related record 71 of the storage unit 27. By doing so, the period is registered. Hereinafter, the cycle for performing the automatic lock check process is referred to as an “automatic lock check cycle”.

  The automatic lock check cycle is preferably about 24 hours or 48 hours. If it is longer than the above time, the period during which the mobile phone 1 can be freely operated becomes longer, which adversely affects security. On the other hand, if the time is shorter than the above time, the frequency of authentication processing using the ID number of the non-contact IC increases, which is complicated for the user.

  The automatic lock setting unit 64 stores the current date and time as the latest check date and time in the automatic lock related record 71 when the user operates the operation unit 26 to instruct the start of automatic lock. As a result, after the automatic lock check cycle has elapsed from the current date and time, the automatic lock check unit 65 starts the automatic lock check process. When the start of automatic lock is instructed, the automatic lock setting unit 64 may perform an authentication process using the ID number of the non-contact IC.

  The automatic lock check unit 65 reads the automatic lock check cycle and the latest check date and time from the automatic lock related record 71, and executes the following automatic lock check process when the automatic lock check cycle elapses from the latest check date and time. It is.

  That is, the automatic lock check unit 65 displays the reading menu of the non-contact IC card 50 on the main screen 10 and, when a reading operation is performed, is the same as the authentication process by the ID number of the non-contact IC in the lock release unit 62. Perform the authentication process. If authentication is successful, the latest check date is updated to the current date without locking. As a result, the automatic lock check unit 65 waits until the next automatic lock check cycle elapses. On the other hand, when the authentication fails or when an operation other than the reading operation is performed, the automatic lock check unit 65 instructs the lock control unit 61 to perform the lock. Note that the unlocking unit 62 executes unlocking when the locking is performed.

  The automatic lock postponing unit 66 performs an authentication process similar to the authentication process in the automatic lock check unit 65 before the automatic lock check process starts, and updates the latest check date and time to the current date and time when the authentication is successful. To do. This makes it possible to postpone the time for starting the automatic lock check process.

  Next, the detailed configuration of the automatic lock-related record 71 in the storage unit 27 and the processing operation related to the automatic lock in the control unit 31 will be described with reference to FIGS.

  FIG. 12 shows the configuration of the automatic lock related record 71 in the storage unit 27. As shown in the figure, the automatic lock-related record 71 has a configuration including an automatic lock check cycle and the latest check date and time. The automatic lock related record 71 is preferably stored in the non-volatile memory in the same manner as the lock related record 70.

  As described above, the automatic lock check cycle indicates a cycle in which the automatic lock check unit 65 performs the automatic lock check process, and is stored as a numerical value in minutes. When the automatic lock check cycle is not registered, “0” is stored in the automatic lock check cycle.

  As described above, the latest check date and time indicates the date and time when automatic lock is started by the automatic lock setting unit 64 or the latest date and time when authentication processing is performed using the ID number of the non-contact IC. It is remembered. If the latest check date is not registered, “0” is stored in the latest check date. On a general computer, the date and time is expressed as the number of seconds elapsed since January 1, 1970. Therefore, it is desirable that the latest check date and time be expressed in minutes.

  FIG. 13 shows the flow of registration processing of the automatic lock check cycle. As shown in the figure, first, the user operates the operation unit 26 to select an automatic lock check cycle registration menu (S50). Then, the automatic lock cycle registration unit 63 refers to the lock-related record 70 to determine whether or not the number of registered non-contact ICs is other than 0, that is, whether or not the ID number of the non-contact IC is registered. Judgment is made (S51).

  If the registration number is other than 0, that is, if the ID number of the non-contact IC has already been registered (YES in S51), the process proceeds to step S52. On the other hand, when the number of registrations is 0, that is, when the ID number of the non-contact IC is not registered (NO in S51), the non-contact IC information registration unit 60 registers the non-contact IC information (see FIG. 8 to execute S10 to S16). Thereafter, the process proceeds to step S52.

  Next, the automatic lock cycle registration unit 63 controls the main display unit 28 or the audio output unit 24 to instruct the input of the automatic lock check cycle (S52). Next, the automatic lock cycle registration unit 63 stores and registers the automatic lock check cycle acquired from the user via the operation unit 26 in the predetermined data area of the automatic lock related record 71 (S53).

  Further, the latest check date and time in the automatic lock related record 71 is updated to 0 (S54). This is to clarify that the latest check date is unregistered. Thereafter, the registration process of the automatic lock check cycle is terminated.

  FIG. 14 shows the flow of the automatic lock start process. As shown in the figure, first, the user operates the operation unit 26 to set the automatic lock start (S60). Then, the automatic lock setting unit 64 determines whether or not the automatic lock check cycle has been set (registered), that is, whether or not the automatic lock check cycle stored in the automatic lock related record 71 is other than 0. Is determined (S61).

  If the automatic lock check cycle has been registered (YES in S61), the process proceeds to step S62. On the other hand, if the automatic lock check cycle is not registered (NO in S61), the automatic lock cycle registration unit 63 is instructed to execute the automatic lock check cycle registration process (S50 to S54 in FIG. 13). To do. Thereafter, the process proceeds to step S62.

  Next, the automatic lock setting unit 64 records and registers the current date and time in the automatic lock related record 71 as the latest check date and time (S62). Thereafter, the automatic lock start process is terminated.

  FIG. 15 shows the flow of the automatic lock check process. As shown in the figure, first, the automatic lock check unit 65 waits until an event is acquired for 1 minute (S70). This 1-minute event is a message notified to each application from the time management unit (not shown) in the mobile phone 1 every minute. Each application starts execution by acquiring the 1-minute event. Often to do. Note that a one-minute event may not reach another application because it is used to execute a certain application.

  When the 1-minute event is acquired, the automatic lock check unit 65 determines whether or not the mobile phone 1 is locked (S71). This determination can be made by the automatic lock check unit 65 inquiring of the lock control unit 61 or by referring to the flag if a flag indicating whether or not the lock state is provided. If the mobile phone 1 is already in the locked state, it is not necessary to set the mobile phone 1 in the locked state again, so the process returns to step S70 and the above processing operation is repeated. On the other hand, if the mobile phone 1 is not in the locked state, the process proceeds to the next step S72.

  Next, the automatic lock check unit 65 determines whether or not the latest check date and time has been set (registered), that is, whether or not the latest check date and time stored in the automatic lock related record 71 is other than 0. Is determined (S72). If the latest check date is unregistered, the automatic lock setting unit 64 has not executed the automatic lock start process, so the process returns to step S70 and repeats the above processing operation. On the other hand, if the latest check date has been registered (YES in S72), the process proceeds to the next step S73.

  Next, the automatic lock check unit 65 acquires the current date and time from the calendar clock 32 (S73), and calculates the difference between the acquired current date and time and the latest check date and time stored in the automatic lock related record 71. (S74).

  Next, the automatic lock check unit 65 determines whether or not the calculated difference is equal to or longer than the automatic lock check cycle stored in the automatic lock related record 71 (S75). If the difference is less than the automatic lock check cycle (NO in S75), the automatic lock check cycle has not yet elapsed from the start date / time of automatic lock or the previous check date / time. Repeat the operation. On the other hand, if the difference is equal to or longer than the automatic lock check cycle (YES in S75), the process proceeds to the next step S76.

  Next, the automatic lock check unit 65 controls the main display unit 28 to display a non-contact IC reading menu on the main screen 10 (S76), and the user operates the operation unit 26 to operate the non-contact IC card. It is determined whether an operation other than reading 50 has been performed (S77). Thereby, it waits until a user performs some operation, and the situation where it was in a locked state without the user's knowledge can be avoided.

  When an operation other than reading of non-contact IC card 50 is performed (YES in S77), automatic lock check unit 65 considers that there is no intention to perform authentication, and instructs lock control unit 61 to carry it. The operation mode of the telephone 1 is set to the locked state (S79). Thereafter, the automatic lock check process is terminated. The unlocking is executed by the unlocking unit 62 performing the unlocking process shown in FIG.

  On the other hand, when a read operation of non-contact IC card 50 is performed (NO in S77), automatic lock check unit 65 performs authentication processing similar to steps S31 to S39 shown in FIG. If successful (YES in S33 or YES in S36), the current date and time is recorded in the automatic lock related record 71 as the latest check date and time without setting the operation mode of the mobile phone 1 to the locked state. (S78). Thereafter, the process returns to step S70 and the automatic lock check process is continued.

  If steps S76 to S78 are omitted and the difference is equal to or greater than the automatic lock check cycle (YES in S75), that is, the automatic lock check cycle has elapsed from the start date / time of automatic lock or the previous check date / time. In such a case, the operation mode of the mobile phone 1 may be locked (S79).

  FIG. 16 shows the automatic lock postponing process. As shown in the figure, first, the automatic lock postponement unit 66 controls the main display unit 28 to display a read menu of a non-contact IC for postponing automatic lock on the main screen 10 (S80). Next, the automatic lock postponing unit 66 refers to the lock related record 70 and determines whether or not the number of registered non-contact ICs is other than 0 (S81).

  If the number of registrations is other than 0 (YES in S81), the ID number of the non-contact IC has already been registered, and the process proceeds to the next step S82. On the other hand, when the number of registrations is 0 (NO in S81), since the ID number of the non-contact IC is not registered, the non-contact IC information registration unit 60 performs the registration process of non-contact IC information ( 8 is instructed to be executed, and then the automatic lock cycle registration unit 63 is instructed to execute automatic lock check cycle registration processing (S50 to S54 in FIG. 13). Thereafter, since the automatic lock has not yet started, the automatic lock postponing process is terminated.

  Next, the automatic lock extension unit 66 determines whether or not the automatic lock check cycle has been set (registered), that is, whether or not the automatic lock check cycle stored in the automatic lock related record 71 is other than 0. Is determined (S82). When the automatic lock check cycle is not registered (NO in S61), the automatic lock cycle registration unit 63 is instructed to execute the automatic lock check cycle registration process (S50 to S54 in FIG. 13). Thereafter, since the automatic lock has not yet started, the automatic lock postponing process is terminated.

  On the other hand, when the automatic lock check cycle has been registered (YES in S82), the automatic lock postponing unit 66 performs the same authentication process as steps S31 to S39 shown in FIG. (YES at S33 or YES at S36), the current mode is recorded and registered in the automatic lock related record 71 as the latest check date without setting the operation mode of the mobile phone 1 to the locked state ( S83). Thereafter, the automatic lock postponing process is terminated.

[Embodiment 3]
Next, another embodiment of the present invention will be described with reference to FIGS. The cellular phone 1 of the present embodiment is different from the cellular phone 1 shown in FIGS. 11 to 16 in the configuration of the control unit and the data stored in the storage unit, and the other configurations are the same. In addition, the same code | symbol is attached | subjected to the structure and process which have the function similar to the structure and process demonstrated in the said embodiment, and the description is abbreviate | omitted.

  In the mobile phone 1 of the present embodiment, a non-contact IC card 50 is provided in a charger 80 that accommodates and charges the mobile phone 1, and the mobile phone 1 contacts the charger 80 after a predetermined time has elapsed. Access to the IC card 50 is performed and authentication is performed using the ID number of the contactless IC. If the access is impossible or the authentication fails, the mobile phone 1 is automatically locked.

  For this reason, the non-contact IC card 50 provided in the charger 80 is disposed at a position accessible by the reader / writer 12 of the mobile phone 1 when the mobile phone 1 is accommodated in the charger 80. The lock-related record 70 stored in the storage unit 27 has a non-contact IC registration number of 1 or a non-contact IC card 50 read out from the non-contact IC card 50 when the unlocking condition at the time of multiple ID registration is set. The condition is that the ID number of the IC matches one of the ID numbers of the plurality of non-contact ICs stored in the lock-related record 70.

  According to the above configuration, this prevents a third party from using a predetermined function of the mobile phone 1 even if the mobile phone 1 is lost or stolen without performing a lock operation. The lock can be automatically performed after a predetermined time has elapsed.

  By the way, in the case of the mobile phone 1, when not using the mobile phone 1 such as at midnight, the mobile phone 1 is placed on the charger 80 and charged. Accordingly, the non-contact IC card 50 is provided in the charger 80, and can be automatically locked when authentication by the non-contact IC card 50 cannot be performed at a predetermined time. Normally, the user does not carry the cradle-type charger 80 that accommodates the mobile phone 1, so even if the user is lost or stolen with the other contactless IC card 50 while carrying the mobile phone 1, It can be securely locked.

  FIG. 17 shows a schematic configuration of the control unit 31 and the storage unit 27 and the charger 80 (portable electronic device container) in the mobile phone 1 of the present embodiment. Compared with the control unit 31 shown in FIG. 11, the control unit 31 of this embodiment is provided with an automatic lock time registration unit 67 instead of the automatic lock cycle registration unit 63, and the automatic lock postponement unit 66 is omitted. . Further, the automatic lock setting unit 68 and the automatic lock check unit (automatic lock means) 69 in the control unit 31 of this embodiment have functions compared to the automatic lock setting unit 64 and the automatic lock check unit 65 shown in FIG. Similar, but with different processing operations. Further, the automatic lock-related record 72 stored in the storage unit 27 of the present embodiment is different in configuration from the automatic lock-related record 71 shown in FIG. In addition, the other structure in the control part 31 and the memory | storage part 27 is the same.

  The automatic lock time registration unit 67 acquires the time at which the automatic lock check unit 69 performs the automatic lock check process from the user via the operation unit 26, and stores the acquired time in the automatic lock related record 72 of the storage unit 27. By doing so, the above time is registered. Hereinafter, the time for performing the automatic lock check process is referred to as “automatic lock check time”. The automatic lock check time is preferably set from a time zone in which the user places the mobile phone 1 on the charger 80, for example, at midnight.

  When the user operates the operation unit 26 to instruct the start of automatic lock, the automatic lock setting unit 68 is the latest date and time before the current time and the time is the automatic lock check time. "Automatic lock check date and time") is stored in the automatic lock related record 72 as the latest check date and time. For example, if the automatic lock check time is 3:00 and the user instructs the start of automatic lock at 10:00 on October 1, the latest automatic lock check date and time before the current time is 3:00 on October 1, The latest check date and time is stored in the automatic lock related record 72.

  Thus, after the automatic lock check time after the current time has elapsed, the automatic lock check unit 69 starts the automatic lock check process. When the start of automatic lock is instructed, the automatic lock setting unit 68 may perform an authentication process using the ID number of the non-contact IC.

  The automatic lock check unit 69 reads the automatic lock check time and the latest check date and time from the automatic lock related record 72, and when 24 hours have elapsed from the latest check date and time, controls the reader / writer 12 to contact the IC card. 50 is accessed, and the authentication process using the ID number of the non-contact IC is performed. If the authentication is successful, the latest check date and time is updated to the latest automatic lock check date and time before the current time without locking. Thereby, the automatic lock check unit 69 stands by until the next automatic lock check time elapses. On the other hand, when access to the non-contact IC card 50 is impossible or authentication fails, the automatic lock check unit 69 instructs the lock control unit 61 to perform locking. Note that the unlocking unit 62 executes unlocking when the locking is performed.

  Next, the detailed configuration of the automatic lock related record 72 in the storage unit 27 and the processing operation related to the automatic lock in the control unit 31 will be described with reference to FIGS.

  FIG. 18 shows a configuration of the automatic lock related record 72 of the storage unit 27. As shown in the figure, the automatic lock related record 72 includes an automatic lock check time, a check time registration flag indicating whether or not the automatic lock check time has been registered, a check valid flag indicating whether or not the automatic lock check function is valid, And the latest check date and time. The automatic lock related record 72 is preferably stored in the non-volatile memory like the lock related record 70.

  As described above, the automatic lock check time indicates the time when the automatic lock check unit 69 performs the automatic lock check process, and is stored as a numerical value in minutes. Further, as described above, the latest check date / time is the latest automatic lock check date / time before the automatic lock start date / time by the automatic lock setting unit 68 or the date / time before the authentication process using the ID number of the non-contact IC. Shows the date and time of the latest automatic lock check, and is stored as a numerical value in minutes. If the latest check date is not registered, “0” is stored in the latest check date. On a general computer, the date and time is expressed as the number of seconds elapsed since January 1, 1970. Therefore, it is desirable that the latest check date and time be expressed in minutes.

  FIG. 19 shows the flow of the automatic lock check time registration process. As shown in the figure, first, the user operates the operation unit 26 to select an automatic lock check time registration menu (S90). Then, the automatic lock time registration unit 67 refers to the lock-related record 70 to determine whether or not the non-contact IC registration number is other than 0, that is, whether or not the non-contact IC ID number is registered. Judgment is made (S91).

  If the registration number is other than 0, that is, if the ID number of the non-contact IC has already been registered (YES in S91), the process proceeds to step S92. On the other hand, when the number of registrations is 0, that is, when the ID number of the non-contact IC is not registered (NO in S91), the non-contact IC information registration unit 60 registers the non-contact IC information (see FIG. 8 to execute S10 to S16). Thereafter, the process proceeds to step S92.

  Next, the automatic lock time registration unit 67 controls the main display unit 28 or the audio output unit 24 to instruct the input of the automatic lock check time (S92). Next, the automatic lock time registration unit 67 stores and registers the automatic lock check time acquired from the user via the operation unit 26 in a predetermined data area of the automatic lock related record 72 (S93).

  In addition, the automatic lock time registration unit 67 sets the check time registration flag in the automatic lock related record 72 to on (registered) and sets the check valid flag to off (invalid) (S94). Thereafter, the automatic lock check time registration process is terminated.

  FIG. 20 shows the flow of the automatic lock start process. As shown in the figure, first, the user operates the operation unit 26 to set the automatic lock start (S100). Then, the automatic lock setting unit 68 refers to the check time registration flag of the automatic lock related record 72 and determines whether or not the automatic lock check time has been set (registered) (S101).

  If the automatic lock check time has already been registered (YES in S101), the process proceeds to step S102. On the other hand, if the automatic lock check time is not registered (NO in S101), the automatic lock time registration unit 67 is instructed to execute the automatic lock check time registration process (S90 to S94 in FIG. 19). To do. Thereafter, the process proceeds to step S102.

  Next, the automatic lock setting unit 68 sets the latest check date and time to the latest automatic lock check date and time before the current time (start date and time of automatic lock), and records it in the automatic lock related record 72 (S102). Further, the check valid flag in the automatic lock related record 72 is set to on (valid) (S103). Thereafter, the automatic lock start process is terminated.

  FIG. 21 shows the flow of the automatic lock check process. As shown in the figure, first, the automatic lock check unit 69 waits until an event for 1 minute is acquired (S110). When the one-minute event is acquired, the automatic lock check unit 69 determines whether or not the mobile phone 1 is in a locked state (S111). If the mobile phone 1 is already in the locked state, it is not necessary to set the mobile phone 1 in the locked state again, so the process returns to step S110 and the above processing operation is repeated. On the other hand, when the mobile phone 1 is not in the locked state, the process proceeds to the next step S112.

  Next, the automatic lock check unit 69 acquires the current date and time from the calendar clock 32 (S112), and whether or not the acquired current time has passed the automatic lock check time set in the automatic lock related record 72. Is determined (S113). If not (NO in S113), the process returns to step S110 and the above operation is repeated. On the other hand, if it has elapsed (YES in S113), the process proceeds to step S114.

  Next, the automatic lock check unit 69 calculates a difference between the acquired current date and time and the latest check date and time stored in the automatic lock related record 72 (S114), and the calculated difference is 24 hours or more. Whether or not (S115). If the difference is less than the automatic lock check cycle (NO in S115), the process returns to step S110 and the above operation is repeated. On the other hand, if the difference is equal to or longer than the automatic lock check cycle (YES in S115), the process proceeds to the next step S116.

  Next, the automatic lock check unit 69 controls the reader / writer 12 to read the ID number of the non-contact IC from the non-contact IC card 50 (S116), and the read ID number of the non-contact IC becomes the unlock condition. It is determined whether or not they match (S117). If they match (YES in S117), the latest check date and time is recorded in the automatic lock related record 72 as the latest automatic lock check date and time before the present time without setting the operation mode of the mobile phone 1 to the locked state. And register (S118). Thereafter, the process returns to step S110 to continue the automatic lock check process.

  On the other hand, if they do not match or if the ID number of the non-contact IC cannot be read (NO in S117), the automatic lock check unit 69 instructs the lock control unit 61 to operate the mobile phone 1 in the operation mode. Is set to the locked state (S119). Thereafter, the automatic lock check process is terminated. The unlocking is executed by the unlocking unit 62 performing the unlocking process shown in FIG.
