(Embodiment)
Hereinafter, an information management system, a portable terminal, an information management method, and a program according to an embodiment of the present invention will be described with reference to FIGS. First, the configuration of the information management system and the mobile terminal in the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration of an information management system according to an embodiment of the present invention.

  As shown in FIG. 1, the information management system 10 according to the present embodiment includes a mobile terminal 100 having a telephone function and a management server 200. In the example of FIG. 1, only one mobile terminal 100 is illustrated, but in reality, the information management system 10 is configured by a plurality of mobile terminals 100. The mobile terminal 100 is connected to the management server 200 via a network 300 including a telephone network and the Internet.

  The management server 200 includes a storage unit 210. The storage unit 210 stores and manages a telephone directory 212 used by the mobile terminal 100, an incoming call history 213 of the mobile terminal 100, and an outgoing call history 214 of the mobile terminal 100 as telephone information.

  Among the telephone information, the telephone book 213 is a set of information registered by the user of the mobile terminal 100, such as the name of the other party, a telephone number, an e-mail address, and an address. The incoming call history 214 is a history of incoming calls received by the mobile terminal 100, and the outgoing call history 214 is a history of outgoing calls made by the user using the mobile terminal 100. In the present embodiment, the telephone directory 213, the incoming call history 214, and the outgoing call history 214 are generated by the mobile terminal 100, transmitted to the management server 200, and managed by the management server 200. At this time, these pieces of information are deleted from the portable terminal 100 as will be described later.

  The mobile terminal 100 mainly includes an information acquisition unit 125, a storage unit 110, an information update unit 126, an information deletion unit 127, and an information communication unit 129. Among these, the information acquisition unit 125 acquires telephone information (phone book 212, incoming call history 213, outgoing call history 214) from the management server 200 when the telephone function is used.

  The storage unit 110 stores the telephone information acquired by the information acquisition unit 125. In FIG. 1, a telephone book 113, an incoming call history 114, and an outgoing call history 115 indicate telephone information acquired by the information acquisition unit 125 and then stored in the storage unit 110.

  When the mobile terminal 100 performs any of incoming call, outgoing call, and change of the phone book, the information update unit 126 stores the phone information (phone book 113, incoming call history 114, The outgoing call history 115) is updated. The information communication unit 129 transmits the updated telephone information to the management server 200 when the use of the telephone function ends. Further, when the updated telephone information is transmitted to the management server 200 by the information communication unit 129, the information deletion unit 127 deletes the telephone information stored in the storage unit 110.

  As described above, in this embodiment, when the telephone function is not used, the mobile terminal 100 does not leave any telephone information such as the telephone book 113, the incoming call history 114, and the outgoing call history 115. Therefore, according to the present embodiment, telephone information such as the telephone book 113, the incoming call history 114, and the outgoing call history 115 is not lost, and even if the portable terminal 100 is in the hands of a third party, No information is leaked.

  Here, the information management system 10 in this Embodiment, the portable terminal 100 which comprises this, and the management server 200 are demonstrated more concretely. In the present embodiment, mobile terminal 100 is a mobile phone or a smartphone.

  In the present embodiment, storage unit 110 stores terminal information 111 and authentication information 112 in addition to phone book 113, incoming call history 114, and outgoing call history. However, the storage unit 110 temporarily stores these pieces of information only while the telephone function is used. The storage unit 110 is realized by a memory mounted on the mobile terminal 100. The memory may be a RAM (Random Access Memory) constituting a computer mounted on the portable terminal 100, or a general-purpose semiconductor storage device such as SD (Secure Digital).

  The terminal information 111 is information for identifying the mobile terminal 110. A specific example of the terminal information 111 is an individual identification number. The authentication information 112 is information used when an authentication request unit 121 described later requests the management server 200 for authentication. Specific examples of the authentication information 112 include a user ID and a password. The terminal information 111 and the authentication information 112 are input, for example, by a key operation by the user when using the telephone function. In this case, the information update unit 126 stores the input information in the storage unit 110 and registers them.

  In addition to the configuration described above, the portable terminal 100 further includes an authentication request unit 121, an encryption / decryption unit 122, an outgoing / incoming information acquisition unit 123, an event detection unit 124, and a terminal monitoring unit 128. Moreover, each part which comprises the portable terminal 100 is realizable by carrying out program control of the computer (not shown) mounted in the portable terminal 100 so that it may mention later.

  The authentication request unit 121 requests the management server 200 for authentication. In the present embodiment, the authentication request unit 121 mainly requests authentication from the management server 200 before the telephone information is acquired by the information acquisition unit 125. At this time, the authentication request unit 121 transmits the above-described terminal information 111 and authentication information 112 to the management server 200 described later via the information communication unit 129.

  And if the authentication part 221 of the management server 200 mentioned later determines that authentication is normal, the information acquisition part 125 of the portable terminal 100 will be able to access the management server 200. FIG. Then, the information acquisition unit 125 can acquire telephone information from the management server 200.

  The encryption / decryption unit 122 encrypts or decrypts various information. For example, the encryption / decryption unit 122 is transmitted when the information communication unit 129 transmits the telephone information (phone book 113, incoming call history 114, outgoing call history 115) stored in the storage unit 110 to the management server 200. Encrypt the target phone information. Also, the encryption / decryption unit 122 is configured such that when the information communication unit 129 transmits the terminal information 111 and the authentication information 112 stored in the storage unit 110 to the management server 200 according to an instruction from the authentication request unit 121, The information 111 and the authentication information 112 are encrypted. On the other hand, the encryption / decryption unit 122 decrypts the acquired telephone information when the telephone information acquired by the information acquisition unit 125 is encrypted.

  The terminal monitoring unit 128 monitors the state of the mobile terminal 100, and detects a transmission operation, an incoming operation, and a change (new registration, correction, deletion) of the phone book 113 in the mobile terminal 100 when they occur. In addition, the terminal monitoring unit 128 notifies the event detection unit 124 of the detection result.

  The event detection unit 124 monitors the occurrence of an event that occurs in the mobile terminal 100 based on the detection result from the terminal monitoring unit 128. When the event detection unit 124 detects the occurrence of an event, the event detection unit 124 notifies each corresponding unit of the detection of the event. For example, when the terminal information 111 and the authentication information 112 are registered in the storage unit 110 and when the telephone information is updated, the event detection unit 124 notifies the authentication request unit 121 of the occurrence of these events. When the telephone information from the management server 200 is received, the event detection unit 124 notifies the information acquisition unit 125 of the occurrence of the event.

  When the mobile terminal 100 makes a call or an incoming call, the event detection unit 124 detects the call or the incoming call via the terminal monitoring unit 128 and notifies the outgoing / incoming information acquisition unit 123 of the occurrence of the event. Upon receiving the notification from the event detection unit 124, the outgoing / incoming information acquisition unit 123 receives information about the outgoing call (name of the destination, telephone number, outgoing time, etc.) or information about the incoming call (name of incoming caller, telephone number, incoming time) And the acquired information is output to the information update unit 126.

  Further, in the present embodiment, the storage unit 210 of the management server 200 stores and manages terminal authentication information 211 in addition to the above-described phone book 212, incoming call history 213, and outgoing call history 214. The terminal authentication information 211 includes terminal information 111 and authentication information 112 set for each portable terminal 100, and is used by the authentication unit 221 described later. The terminal authentication information 211 is stored and registered at the time of initial setting.

  In the present embodiment, the management server 200 includes an authentication unit 221, an encryption / decryption unit 222, an information processing unit 223, and an information communication unit 224 in addition to the storage unit 210. Furthermore, each part which comprises the management server 200 is implement | achieved by carrying out program control of the server computer.

  The authentication unit 221 performs authentication for the mobile terminal 100 when authentication is requested by the authentication request unit 121 of the mobile terminal 100. Specifically, when the authentication unit 221 acquires the terminal information 111 and the authentication information 112 transmitted by the mobile terminal 100, the authentication unit 221 determines whether these and the terminal authentication information 212 match. The authentication unit 221 determines that the authentication is normal when they match, and determines that the authentication is not normal when they do not match.

  In addition, the information communication unit 224 performs transmission of information to the mobile terminal 100 and reception of information from the mobile terminal 100 based on a request from the mobile terminal 100. The encryption / decryption unit 222 encrypts information to be transmitted to the mobile terminal 100 and decrypts information received from the mobile terminal 100. For example, since the terminal information 111 and the authentication information 112 transmitted by the mobile terminal 100 are encrypted, the encryption / decryption unit 22 decrypts them.

  The information processing unit 223 executes processing such as registration, update, and extraction of the terminal authentication information 211, the phone book 212, the incoming call history 213, and the outgoing call history 214. For example, when the phone book 212, the incoming call history 213, and the outgoing call history 214 are newly transmitted from the mobile terminal 100, the information processing unit 223 stores them in the storage unit 210 and registers them.

  In addition, when information for updating the registered phone book 212, incoming call history 213, and outgoing call history 214 is transmitted from the mobile terminal 100, the information processing unit 223 updates them. Further, when acquisition of the phone book 212, the incoming call history 213, and the outgoing call history 214 is requested from the information acquisition unit 125 of the mobile terminal 100, the information processing unit 223 extracts them from the storage unit 210.

  Next, processing performed in the information management system 10 (the mobile terminal 100 and the management server 200) in the embodiment of the present invention will be described with reference to FIGS. In the following description, FIG. 1 is taken into consideration as appropriate. Furthermore, in this embodiment, the information management method is implemented by operating the information management system 10. Therefore, the description of the information management method in the present embodiment is replaced with the following description of the operation of the information management system 10.

First, the initial setting process in the portable terminal 100 and the management server 200 will be described with reference to FIGS. FIG. 2 is a flowchart showing an initial setting process performed in the mobile terminal. FIG. 3 is a flowchart showing an initial setting process performed in the management server.

  As shown in FIG. 2, first, when the terminal information 111 and the authentication information 112 are input by the user via the operation keys, the information update unit 126 receives the input terminal information 111 and the authentication information 112 ( Step A1).

  Furthermore, the information update unit 126 stores the received terminal information 111 and authentication information 112 in the storage unit 110 and registers them (step A2). When step A2 is executed, the event detection unit 124 detects registration of the terminal information 111 and the authentication information 112, and notifies the authentication request unit 121 of this.

  Next, the authentication request unit 123 acquires the terminal information 111 and the authentication information 113 stored in the storage unit 110, sends them to the encryption / decryption unit 122, and encrypts them (step A3). Then, the authentication request unit 123 causes the information communication unit 129 to transmit the encrypted terminal information 111 and authentication information 113 to the management server 200 (step A4). As described above, the initial setting operation in the portable terminal 100 is completed by executing Steps A1 to A4.

  On the other hand, as shown in FIG. 3, when step A4 is executed, in the management server 200, the information communication unit 224 receives the encrypted terminal information 111 and authentication information 113 (step A11). Next, the authentication unit 221 causes the information communication unit 224 to send the received terminal information 111 and authentication information 112 to the encryption / decryption unit 222, and causes the encryption / decryption unit 222 to decrypt them (Step S1). A12).

  Next, when the authentication unit 221 sends the decrypted terminal information 111 and authentication information 113 to the information processing unit 223, the information processing unit 223 stores them in the storage unit 210, and further performs terminal authentication thereof. It registers as information 211 (step A13). As described above, the initial setting operation in the management server is completed by executing steps A11 to A13.

[Telephone information acquisition processing]
Next, processing (phone information acquisition processing) when the mobile terminal 100 acquires telephone information (phone book 212, incoming call history 213, outgoing call history 214) from the management server 200 will be described with reference to FIGS. . FIG. 4 is a flowchart showing telephone information acquisition processing performed by the mobile terminal. FIG. 5 is a flowchart showing telephone information acquisition processing performed by the management server.

  As shown in FIG. 4, first, when the user starts using the telephone function in the mobile terminal, the information acquisition unit 125 receives an authentication request via the event detection unit 124 in order to acquire telephone information from the management server 200. The unit 121 is activated. Then, the information acquisition unit 125 causes the authentication request unit 121 to acquire the terminal information 111 and the authentication information 112 stored in the storage unit 110 (Step B1).

  Next, the authentication request unit 121 sends the acquired terminal information 111 and authentication information 112 to the encryption / decryption unit 122 and encrypts them (step B2). Further, the authentication request unit 121 causes the information communication unit 129 to transmit the encrypted terminal information 111 and authentication information 113 to the management server 200 (step B3). Also, the authentication request unit 121 causes the information communication unit 129 to make a transmission request for telephone information to the management server 200 (step B4). Thereafter, steps B11 to B17 shown in FIG. 6 are executed as described later.

  Next, after steps B11 to B17 are executed in the management server 200, the information communication unit 129 receives information indicating the authentication result and telephone information (step B5), and sends them to the encryption / decryption unit 122. Then, the decoding process is performed (step B6).

  Next, when step B6 is executed, the information acquisition unit 16 is activated via the event detection unit 124, so that the authentication request unit 121 sends the decrypted authentication result and telephone information to the information acquisition unit 125. . And the information acquisition part 125 memorize | stores the decoded telephone information in the memory | storage part 110 (step B7). By executing Step B7, the telephone information such as the telephone directory 113, the incoming call history 114, and the outgoing call history 115 is returned to the mobile terminal 100 and eventually the user.

  As described above, the telephone information acquisition process in the portable terminal 100 is completed by executing Steps B1 to B7. Although not shown in FIG. 4, if the authentication in the management server 200 is not normal in steps B11 to B16 shown in FIG. 5, no telephone information is transmitted. For this reason, in this case, the telephone information acquisition process in the portable terminal 100 ends after the execution of Step B5.

  Further, when telephone information is requested inside the portable terminal 100 while the storage unit 110 stores the telephone book 113, the incoming call history 114, and the outgoing call history 115, the management server 200 is accessed. Instead, the telephone information on the portable terminal 100 is used.

  Also, as shown in FIG. 5, when the above-described step B4 is executed, in the management server 200, the information communication unit 224 makes a transmission request for encrypted terminal information 111, authentication information 113, and telephone information. Receive (step B11).

  Next, the authentication unit 221 causes the information communication unit 224 to send the transmission request for the terminal information 111, the authentication information 112, and the telephone information to the encryption / decryption unit 222, and the encryption / decryption unit 222 Is decrypted (step B12).

  Next, the authentication unit 221 extracts the terminal authentication information 211 stored in the storage unit 210, and performs authentication using this, the decrypted terminal information 111, and the authentication information 112 (step B13). Specifically, the authentication unit 221 compares the terminal authentication information 211 with the decrypted terminal information 111 and authentication information 112, and determines whether or not they match.

  When the result of the authentication in step B13 is normal, the information processing unit 223 extracts telephone information such as the phone book 212, the incoming call history 213, and the outgoing call history 214 from the storage unit 210 (step B15). Further, the information processing unit 223 sends the extracted telephone information and information indicating the authentication result to the encryption / decryption unit 222, encrypts them (step B16), and the information communication unit 224 further encrypts them. The telephone information and information indicating the authentication result are transmitted to the portable terminal 100 (step B17).

  On the other hand, if the authentication result in step B13 is not normal, the information processing unit 223 uses the encryption / decryption unit 222 to encrypt information indicating the authentication result indicating that the authentication is not normal. Further, the information processing unit 223 causes the information communication unit 224 to transmit information indicating an authentication result indicating that the information communication unit 224 is not normal to the mobile terminal 100 (step B18). As described above, the telephone information acquisition process in the management server 200 ends by executing Steps B11 to B18.

[Telephone information update processing]
Next, telephone information update processing in the portable terminal 100 will be described with reference to FIG. FIG. 6 is a flowchart showing telephone information update processing performed in the mobile terminal.

  As shown in FIG. 6, first, the event detection unit 124 detects the occurrence of an event in the portable terminal 100 via the terminal monitoring unit 128 after the telephone information acquisition process shown in FIG. 5 is completed (step C1). . Next, the event detection unit 124 determines whether or not the generated event is a call such as outgoing or incoming (step C2).

  As a result of the determination in step C2, if the event that has occurred is a call, the event detection unit 124 causes the call origination / incoming information acquisition unit 123 to acquire information about outgoing calls or information about incoming calls (step C3). In step C <b> 3, the outgoing / incoming call information acquisition unit 123 outputs the acquired information to the information update unit 126.

  Next, the information update unit 126 updates the incoming call history 114 or the outgoing call history 115 stored in the storage unit 110 based on the information output by the incoming / outgoing information acquisition unit 123 (step C4).

  On the other hand, as a result of the determination in step C2, if the event that has occurred is not a notification, that is, if the user has changed the phone book, the event detection unit 124 identifies the change content added to the phone book and changes it. Information specifying the content is output to the information updating unit 126 (step C5).

  Next, the information update unit 126 updates the telephone book 113 stored in the storage unit 110 based on the information output by the event detection unit 124 (step C6).

  As described above, the execution of steps C1 to C6 ends the telephone information update process. However, in the present embodiment, steps C1 to C6 may be repeatedly executed as long as the use of the telephone function is not terminated.

[Transmission / deletion of phone information]
Next, the mobile terminal 100 transmits the updated telephone information to the management server 200, and then the process when the telephone information is deleted from the mobile terminal 100 (telephone information transmission / deletion process) is shown in FIG. And it demonstrates using FIG. FIG. 7 is a flowchart showing telephone information transmission / deletion processing performed in the portable terminal. FIG. 8 is a flowchart showing telephone information transmission / deletion processing performed by the management server.

  As shown in FIG. 7, first, when the user ends the use of the telephone function in the portable terminal, the event detection unit 124 detects the end of the use of the telephone function via the terminal monitoring unit 128 (step D1). .

  Here, as “when the use of the telephone function is terminated”, for example, when the user terminates the call and disconnects the line, any one of the incoming call, outgoing call, and change of the telephone book 113 is finally performed. In this case, the set time has elapsed since In addition, if the mobile terminal is provided with a button for turning off the telephone function, the case where the button is pressed may be mentioned. The event detection unit 124 detects these cases as the starting point of the process.

  Next, the event detection unit 124 activates the authentication request unit 121. Then, the information acquisition unit 125 causes the authentication request unit 121 to acquire the terminal information 111 and the authentication information 121 stored in the storage unit 110 (Step D2).

  Next, the authentication request unit 121 sends the acquired terminal information 111 and authentication information 112 to the encryption / decryption unit 122, and encrypts them (step D3). Further, the authentication request unit 121 causes the information communication unit 129 to transmit the encrypted terminal information 111 and authentication information 112 to the management server 200 (step D4). Thereafter, as will be described later, steps D11 to D14 shown in FIG. 8 are executed.

  Next, the information communication part 129 receives the information which shows an authentication result, after step D11-D14 are performed in the management server 200 (step D5). In this case, the information communication unit 129 sends the received information to the encryption / decryption unit 122 to perform a decryption process.

  And the authentication request | requirement part 121 determines whether authentication was performed normally based on an authentication result (step D6). If the result of determination in step D <b> 6 is that authentication is not normal, the authentication request unit 121 ends the process in the mobile terminal 100. On the other hand, if the authentication is normal as a result of the determination in step D6, the authentication request unit 121 causes step D7 to be executed via the event detection unit 124.

  In step D <b> 7, the event detection unit 124 causes the information update unit 125 to acquire the telephone information stored in the storage unit 110. The telephone information acquired at this time is updated. Further, the authentication request unit 121 encrypts the acquired telephone information by the encryption / decryption unit 122 and then causes the information communication unit 129 to transmit the encrypted telephone information to the management server 200. Thereafter, as will be described later, steps D15 to D17 shown in FIG. 8 are executed, and the management server 200 transmits an update completion notification to the mobile terminal 100.

  Next, the information communication unit 129 receives the update completion notification from the management server 200 (step D8), and the information deletion unit 127 deletes the telephone information stored in the storage unit 110 in response to the notification. (Step D9). As described above, the transmission / deletion process of the telephone information in the portable terminal 100 is completed by executing Steps D1 to D9.

  As shown in FIG. 8, when the above-described step D4 is executed in the mobile terminal 100, the information communication unit 224 receives the encrypted terminal information 111 and authentication information 113 in the management server 200 (step S4). D11).

  Next, the authentication unit 221 causes the information communication unit 224 to send the terminal information 111 and the authentication information 112 to the encryption / decryption unit 222, and causes the encryption / decryption unit 222 to decrypt them (Step D12). ).

  Next, the authentication unit 221 extracts the terminal authentication information 211 stored in the storage unit 210, and performs authentication using this, the decrypted terminal information 111, and the authentication information 112 (step D13). Specifically, the authentication unit 221 compares the terminal authentication information 211 with the decrypted terminal information 111 and authentication information 112, and determines whether or not they match.

  If the authentication result in step D13 is not normal, the information processing unit 223 encrypts information indicating the authentication result indicating that the authentication is not normal by the encryption / decryption unit 222. Furthermore, the information processing unit 223 causes the information communication unit 224 to transmit information indicating an authentication result indicating that the information communication unit 224 is not normal to the mobile terminal 100 (step D18).

  On the other hand, when the authentication result in step D13 is normal, the information processing unit 223 encrypts information indicating the authentication result indicating that the authentication is normal by the encryption / decryption unit 222. Further, the information processing unit 223 causes the information communication unit 224 to transmit information indicating an authentication result indicating normality to the mobile terminal 100 (step D14).

  Next, when step D7 described above is executed in the portable terminal 100, the information communication unit 224 receives the updated latest telephone information in the management server 200 (step D15). Further, the information communication unit 224 sends the received telephone information to the encryption / decryption processing unit 222 to perform decryption.

  Next, the information processing unit 223 uses the decrypted phone information to update the phone information stored in the storage unit 210 (step D16). Thereafter, the information processing unit 223 transmits an update completion notification to the mobile terminal 100 via the information communication unit 224 (step D17). As described above, the transmission / deletion process of the telephone information in the management server 200 is completed by executing Steps D11 to D18.

  As described above, in the present embodiment, the telephone information exists in the portable terminal 100 only when it is used, and the telephone information is deleted from the portable terminal 100 after use. Therefore, as compared with the case where the mobile terminal 100 is simply provided with the lock function, according to the present embodiment, the telephone information can be protected at the mobile terminal at a very high level.
