Description

Fingerprint recognition door lock system

The present invention relates to a fingerprint recognition door opening and closing system, and more particularly, a fingerprint for each transmitter in a fingerprint recognition door opening and closing system that can open a door by controlling a receiver installed in a door using a transmitter having a fingerprint recognition function. It relates to a fingerprint door opening and closing system that can register and temporarily delegate the authority to use the sender to others.

Traditionally, the door opening and closing device is a metal key that opens or closes a lock installed on a door. However, when a plurality of doors are accessed by a plurality of doors such as a hotel or an intelligent building, it is difficult to manage keys because the keys used for each door are different.

In order to solve this problem, an apparatus for opening and closing a door using an ID card storing personal information has been proposed and used. However, even in this case, there is a fear that another person may acquire an ID card and enter or exit without permission, and there is a fear of illegal use due to the rental of the ID card.

In order to solve this problem, a system has been proposed and used to open the door by using physical characteristics that can be uniquely distinguished from individual such as iris and fingerprint.

In the case of a conventional door opening device using a fingerprint, a fingerprint recognition sensor is installed in the door, so that when the user touches the finger, the door opening device recognizes the fingerprint, and the door is opened when the user is a registered legitimate user.

However, in this case, the user has to go to the door opening device installed in the door and place a finger to register the fingerprint, which is cumbersome. In addition, since the fingerprint recognition sensor is exposed to the outside, fingerprint information may leak to an outsider or the fingerprint recognition sensor may be contaminated or damaged.

In order to solve this problem, the present inventor has proposed a door opening device using a portable fingerprint recognition key. That is, when a user carries a portable fingerprint recognition key having a fingerprint recognition sensor and a wireless communication circuit like a general key or an ID access card, and the user recognizes the fingerprint using the portable fingerprint identification key, the door lock is installed on the door. Wirelessly delivered to the opening device, the door lock opening device is to open the door when authentication is made using the received information.

With respect to various forms of the door opening device using the portable fingerprint recognition key, the present inventors have disclosed Korean Patent Publication No. 2000-0072132, Korean Patent Publication No. 2000-0072206, Korean Patent Application No. 2000-0077260, and Korean Patent Application No. 2000 -0084489, Republic of Korea Patent Application No. 2001-22500, Republic of Korea Patent Application No. 2001-0026584, Republic of Korea Patent Application No. 2001-0076769.

On the other hand, when registering a fingerprint in these systems, only the fingerprint itself was determined regardless of the sender, but if the fingerprint is registered for each sender, the fingerprint search time can be shortened and the risk of unauthorized door opening due to theft of the sender will be reduced. It is an object of the present invention to provide a fingerprint recognition door opening and closing system that can register a fingerprint for each transmitter.

However, if a fingerprint is registered for each sender, the door must be opened using the sender registered by the sender, which is very inconvenient when another person wants to open the door in a hurry or the door needs to be opened instead.

Accordingly, another object of the present invention is to provide a fingerprint recognition door opening and closing system that can delegate the authority to temporarily open a door to another person who has not registered a fingerprint.

The fingerprint recognition door opening / closing system of the present invention includes a plurality of transmitters that scan and transmit fingerprints wirelessly, and one or more receivers mounted on the doors to open and close the doors according to the received fingerprint information.

The transmitter includes a fingerprint recognition unit for scanning a user's fingerprint, a wireless communication unit for wirelessly transmitting the recognized fingerprint information and device information unique to the transmitter, an input unit for selecting a function menu, and an indicator for displaying the state of the transmitter. A display unit, memory for storing the device information unique to the sender and a program necessary for the operation of the device, and when the user operates the input unit to operate the door opening function, the fingerprint information and the transmitter are inputted by the user through the fingerprint recognition unit. And a control unit for transmitting the unique device information through the wireless communication unit.

The receiver includes a wireless communication unit for wirelessly receiving data from a transmitter, a device for storing unique device information, fingerprint information registered for each transmitter, and a program for operating a receiver, and a signal for opening a door lock. A door lock driver for outputting a door, and when the transmitter device information and the fingerprint information received through the wireless communication unit match one of the fingerprint information registered for the corresponding transmitter stored in the memory, the door lock driver controls the door. It includes a control unit for opening.

Meanwhile, the memory of the transmitter stores device information of receivers that can be controlled using the transmitter. When the user selects one of the receivers stored in the memory of the transmitter to operate the door opening function, the controller of the transmitter receives the fingerprint from the user through the fingerprint recognition unit, the fingerprint information, the device information of the transmitter and the device information of the selected receiver. Transmits through the wireless communication unit. The control unit of the receiver matches the received receiver device information with its own device information, and the received sender device information and fingerprint information match one of the fingerprint information registered for the corresponding sender stored in the receiver's memory. In this case, the door lock driving unit is controlled to open the door.

In addition, the sender of the present invention, if the registered user registers his fingerprint to the sender while setting the sender in the authority delegation mode, when the door is opened using the sender instead of requesting the sender to enter the fingerprint It has a delegation function for transmitting a fingerprint registered in.

The user can also set the sender to be unusable unless a password is entered in order to prevent unauthorized use of the sender.

<Fingerprint Registration Procedure by Sender>

A procedure of registering a fingerprint for each sender will be described with reference to FIGS. 4 and 5. 4 is a flowchart showing a procedure at the sender when registering a fingerprint, and FIG. 5 is a flowchart showing a procedure at a receiver when registering a fingerprint.

When registering a fingerprint, authentication of a user whose fingerprint is already registered is required. Therefore, when a fingerprint of a new user is to be registered, it is necessary to receive a fingerprint of an already registered user for the corresponding sender.

On the other hand, when a fingerprint is registered for each originator for the first time, authentication of the master registered in the receiver is required. Therefore, when a transmitter is to be registered for a specific receiver for the first time, the fingerprint of the master should be input.

First, the operation at the transmitter will be described with reference to FIG. 4. A user who wants to register a fingerprint selects a fingerprint registration menu from a menu of a sender (step S401). An example of the function menu of the transmitter is shown in FIG. 7A.

Then, the sender displays a list of receivers that can register a fingerprint (step S402). The list of receivers capable of registering fingerprints may be stored in advance in the memory 131 of the transmitter through the wired transceiver 121 or the wireless communication unit 124. Alternatively, it is possible to search for the receiver 200 that can communicate and display it. For example, when the user selects the transmitter fingerprint registration menu, the control unit 120 of the transmitter 100 sends a signal for requesting device information of a receiver that can communicate through the wireless communication unit 124 and receives the receiver 200. ) Sends its own device information. The transmitter 100 receives it and displays it on the display unit.

The user selects a receiver for fingerprint registration from the displayed receiver list (step S405). Then, the controller 120 of the transmitter 100 displays a message requesting to input a fingerprint of a user who wants to register on the display unit 123 or outputs a voice through the voice reproducing unit 130.

Then, the user touches his finger to the fingerprint recognition unit 111 of the transmitter 100, the control unit 120 scans it, the code indicating that the signal to request the fingerprint information and his device code and fingerprint registration The fingerprint registration information including the transmission is transmitted to the selected receiver 200 (step S409). At this time, it is preferable to also transmit the device code of the receiver 200.

The receiver 200 receiving the fingerprint registration information registers it as a fingerprint for the corresponding transmitter and transmits the result to the transmitter. The procedure in the receiver 200 will be described later.

The transmitter 100 which has transmitted the fingerprint registration information waits for a processing result from the receiver 200 (step S411). If the processing result does not come from the receiver 200 within a predetermined time, go to step S423 to send an error message and complete the fingerprint registration procedure.

When a fingerprint is not registered at all in the receiver 200, that is, when a fingerprint is first registered in the receiver 200, this fingerprint becomes a master fingerprint. In this case, in step S411, a processing result indicating that normal registration is completed from the receiver 200 comes. Then, the transmitter 100 displays the registration result and ends the fingerprint registration procedure (step S421).

If the fingerprint is registered in the receiver 200, the receiver 200 sends a processing result requesting to input the fingerprint of the user who is already registered in the transmitter 100. When the transmitter 100 receives the processing result, the transmitter 100 displays a message requesting to register a fingerprint of a user who is already registered on the display unit 123 or outputs a voice through the voice reproducing unit 130, and prints the fingerprint of the registered user. Is input (step S413).

The transmitter 100 transmits the input fingerprint again to the receiver 200 (step S415), and waits for a processing result to come for a predetermined time (step S417).

If the processing result does not come within a predetermined time, go to step S423 to send an error message and complete the fingerprint registration procedure.

When the processing result is received, it is checked whether the received processing result indicates that normal registration is completed (step S419). If the processing result does not indicate completion of normal registration, go to step S423 to send an error message and complete the fingerprint registration procedure.

If the received processing result indicates normal registration, the flow advances to step S421 to display the registration result and ends the fingerprint registration procedure.

Next, the procedure in the receiver 200 at the time of fingerprint registration will be described with reference to FIG.

Receiving a signal for requesting fingerprint registration from the transmitter 100 in step S501, the receiver 200 temporarily stores the received information in the memory 228, and then the device code of the transmitter included in the received fingerprint registration information. Reference is made to see if there is a fingerprint already registered for the sender (step S503).

If the fingerprint is not registered at all for the sender, the flow goes to step S521 to check whether the master fingerprint is registered for the receiver 200. If the master fingerprint is not registered, since the first fingerprint is registered for the receiver 200, the received fingerprint information is regarded as the master fingerprint and stored as a master fingerprint in the memory 228 of the receiver 200 ( Step S531).

In step S541, the received fingerprint information is registered for the corresponding sender, and in step S543, the processing result informing that it is registered properly is transmitted to the sender 100.

If the master fingerprint is already registered in step S521, there is a case where the first fingerprint registration request using the transmitter 100 is received. In this case, fingerprint registration is required only if the person who registered the master fingerprint is authenticated. Therefore, the receiver 200 transmits the processing result requesting to input the master fingerprint to the transmitter 100 (step S523).

Then wait for the master fingerprint information from the transmitter 100 for a predetermined time (step S525). If the master fingerprint information has not been received within a certain time, go to step S551 and transmits a processing result indicating that registration is impossible to the transmitter 100.

If the master fingerprint information is received within a predetermined time, it is checked whether the data is from the same sender requesting fingerprint registration (step S527), and if it is not the same sender, the transmitter 100 returns a processing result indicating that registration is impossible in step S551. To send).

In the case of data from the same sender, it is checked whether the received fingerprint information matches the master fingerprint information stored in the memory 228 (step S529). If the fingerprint information does not match, in step S551 a processing result indicating that registration is impossible is transmitted to the sender 100.

If the fingerprint information matches, the process goes to step S541, and the fingerprint information stored temporarily in the memory 228 in step S501 is registered in the memory 228 as fingerprint information for the transmitter. In step S543, the processor 100 transmits the processing result notifying that the normal registration is completed to the transmitter 100.

If there is a fingerprint already registered for the sender in step S503, the process proceeds to step S511 and transmits the processing result requesting to input a fingerprint of a pre-registered user to the sender 100.

After that, it waits for fingerprint information of the registered user from the sender 100 for a predetermined time (step S513). If the fingerprint information of the pre-registered user is not received within a certain time, go to step S551 and transmit the processing result to the sender 100 indicating that registration is impossible.

If the fingerprint information of the pre-registered user is received within a certain time, it is checked whether the data is from the same sender requesting fingerprint registration (step S515), and if it is not the same sender, the processing result indicating that registration is impossible in step S551. Send to the transmitter (100).

In the case of data from the same sender, it is checked whether the received fingerprint information matches any one of the fingerprint information of the registered user stored in the memory 228 (step S517). If the fingerprint information does not match, in step S551 a processing result indicating that registration is impossible is transmitted to the sender 100.

If the fingerprint information matches, the process goes to step S541, and the fingerprint information temporarily stored in the memory 228 in step S501 is additionally registered in the memory 228 as fingerprint information for the transmitter. In step S543, the processor 100 transmits the processing result notifying that the normal registration is completed to the transmitter 100.

In the above description, a case in which a fingerprint of a user who wants to register is first scanned and transmitted, and then a fingerprint of a pre-registered user is scanned and transmitted in response to a request from a receiver, but the present invention is not limited thereto. For example, it is also possible to first scan the fingerprint of the pre-registered user, then scan the fingerprint of the user who wants to register, and then transmit these fingerprint information to the receiver all at once. Alternatively, if the fingerprint of the pre-registered user is first scanned and transmitted, the fingerprint of the user who wishes to register may be scanned and transmitted according to a request from the receiver.

<Door opening procedure using fingerprint recognition>

With reference to FIG. 6, the operation | movement in the transmitter 100 at the time of the door opening using a fingerprint is demonstrated.

When the user turns on the power switch of the transmitter 100 to use the transmitter 100, a screen as shown in FIG. 7A appears on the display unit 123 of the transmitter 100. Here the user selects the desired function.

When the user selects the door open menu (step S601), the control unit 120 of the transmitter 100 reads a list of receivers 200 capable of opening the door using the transmitter 100 from the memory 131. It displays on the display part 123 (step S603). An example screen is shown in FIG. 7B.

On the other hand, instead of storing a list of the receiver 200 that can open the door, it is also possible to list only the receivers 200 that can currently communicate after making a communication request in the transmitter 100. That is, when the transmitter 100 transmits a communication request signal, the receiver 200 receiving the signal transmits a response signal. Then, the transmitter 100 displays only the receivers 200 for which the response signal has been received on the display unit 123.

The user selects a door to be opened from the displayed list (step S605). Then, the control unit 120 of the transmitter 100 displays a message requesting a fingerprint input on the display unit 123 and waits for a fingerprint input.

When the user touches the finger on the fingerprint recognition unit 111, the fingerprint recognition unit 111 scans the fingerprint (step S607). If the quality of the scanned fingerprint image is below a certain level, it is possible to require the fingerprint to be input again.

The transmitter 100 scanning the fingerprint transmits the door opening information through the wireless communication unit 124 (step S613). It is also possible to open the channel by first sending a signal to the sender requesting channel opening before transmitting the door opening information. The door opening information includes a code indicating the door opening request signal using fingerprint recognition, device information of the transmitter, and input fingerprint information. In addition, it is preferable to include the device information of the receiver selected by the user.

The transmitter 100 that has transmitted the door opening information waits for a processing result message from the receiver 200 for a predetermined time. If the processing result does not come after a predetermined time passes, the control unit 120 displays an error message on the display unit 123 (step S621).

When the processing result comes from the receiver 200, the control unit 120 displays it on the display unit 123, and stores it in the memory 131 as history information (step S619). The storing of the processing result in the memory is intended to confirm whether or not another person has opened the door by using the transmitter without permission. In some cases, this step may be omitted.

8 is a flowchart illustrating the operation of the receiver 200 when the door opening request using the fingerprint recognition is received from the transmitter 100.

When the communication channel opening request signal comes from the transmitter 100 (step S801), the receiver 200 responds to this signal while transmitting its own device information (step S803). At this time, information for encryption may be exchanged. In addition, it is possible to temporarily store the device information of the transmitter 100 included in the received signal, and to check whether the next signal is from this transmitter.

After responding to the communication channel opening request signal, the receiver 200 waits for the door opening information for a predetermined time (S805). If the door opening information does not come within a certain time, the control unit 210 of the receiver 200 deletes the temporarily stored transmitter information and the like and exits from this routine.

Upon receiving the door opening information from the transmitter 100, the control unit 210 of the receiver 200 confirms whether the information is from the transmitter which has made a communication channel opening request (step S807). If it is not the door opening information from the same transmitter, the control unit 210 stores the fact that there is a door opening request in the memory 228, and transmits the processing result to the corresponding transmitter through the wireless communication unit 212 (step S817). . In addition, the display unit 216 of the receiver 200 may display the processing result.

On the other hand, when the transmitter 100 does not make a communication channel request, steps S801, S803, S805, and S807 can be omitted.

When the received door opening information comes from the transmitter 100 which has requested communication channel opening, the control unit 210 searches the memory 228 to determine whether the transmitter 100 is a registered transmitter. (S809). In the case of a door opening request from an unregistered sender, the flow advances to step S817 to display, store and send the processing result to the sender.

In the case of a door opening request from a registered sender, the controller 210 checks whether fingerprint information included in the door opening information matches among fingerprint information of the corresponding transmitter 100 stored in the memory 228. (Step S811).

If there is no matching fingerprint information, the received fingerprint information is stored in the memory 228 (step S815). This fingerprint information can later be used to find the person who attempted to open the door. In step S817, the processing result is displayed, stored and transmitted to the transmitter.

If there is matching fingerprint information, the controller 210 controls the door lock driver 224 to release the door lock (step S813). In step S817, the processing result is displayed, stored and transmitted to the transmitter.

<Authority Delegation>

If you want to open the door using the transmitter, only the user who registered the fingerprint using the transmitter can open the door. In some cases, however, it is desirable to be able to delegate to open the door to a person who has not registered a fingerprint. For example, if the fingerprint registrant is unable to move, hand the sender to someone else to open the door and run an errand to pick up the object, or leave the transmitter to another person when the fingerprint registrant goes out and the person opens the door. There are cases where it can be opened. In addition, it is cumbersome to register the fingerprint of the guest every time in an environment where the key user changes frequently, such as a hotel. Therefore, in such a case, it would be convenient if the administrator delegated the use authority of the sender whose fingerprint was registered to the receiver installed in the specific room, and then let the guest use the sender.

In such a case, the door opening and closing system of the present invention provides a delegation authority function. That is, if a registered user registers his or her fingerprint with the sender while setting the sender to the authority delegation mode, when the door is opened using the sender, the registered fingerprint is registered instead of requesting the fingerprint to be input. Will be sent out.

A delegation function will be described with reference to FIGS. 9 and 10. 9 is a flowchart illustrating a procedure for setting a delegation mode, and FIG. 10 is a flowchart showing an operation at a transmitter in a state in which delegation is set.

The user who wants to delegate authority selects the authority delegation menu from the menu of FIG. 7A of the transmitter 100 (step S901). Then, the transmitter 100 displays a list of receivers capable of opening the door on the screen (step S903). The user selects a door that can be opened by a person authorized by the authority (step S905). In this case, only a specific door may be opened, or a corresponding user may be set to control all registered receivers. In addition, if step S905 is omitted and the authority is delegated, it is possible to allow the corresponding user to control all the registered receivers.

It is also possible to set the effective time of delegation when delegating authority. If the valid time is to be set, the authority delegation valid time setting menu is selected to set the valid time (step S907). Alternatively, after step S905, a screen for setting the authority delegation validity time is shown, and it is also possible for the user to set the validity time.

After setting the validity time, the sender 100 sends out a screen requesting the input of the registered user's fingerprint, and the user inputs the fingerprint to the sender (step S909). The input fingerprint is stored in the memory 131 of the sender 100, and when the person delegated authority of the sender selects the door open menu, the stored fingerprint is transmitted.

Next, with reference to Fig. 10, the operation of the authority delegated authority will be described.

In the transmitter 100 in which the delegation mode is set, it is checked whether the valid time of the delegation has elapsed (step S1001). This step can be omitted if the delegation validity time has not been set.

When the delegation mode valid time expires, the fingerprint information stored in step S1021 is deleted and the delegation mode is terminated in step S1023.

If the delegation mode valid time has not expired, it is checked whether the user has selected the door opening menu (step S1003). If the door open menu is not selected, the process is repeated from step S1001.

When the user selects the door open menu, a list of devices that have been delegated authority is displayed, and the user selects one of them (step S1004). Then, the transmitter 100 transmits the registered user's fingerprint stored in the memory 131 through the wireless communication unit 124.

The subsequent operation is the same as that in the general door opening step. That is, steps S1007, S1009, S1011, and S1013 of FIG. 10 are the same as those of steps S615, S617, S619, and S621 of FIG. 6, and thus detailed description thereof will be omitted.

Meanwhile, in the delegation mode, the delegation mode may be released at any time regardless of the remaining valid time. That is, in the delegation mode, a menu item "end of delegation mode" is provided in the function menu, and the user can terminate the delegation mode by selecting it.

In addition, when the door opening function is used for a predetermined number of times in the delegation mode, it is possible to automatically release the delegation mode. That is, the controller 120 of the transmitter counts each time the door opening function is used in the authority delegation mode, and automatically releases the authority delegation mode when the number of times of using the door opening function exceeds a predetermined number of times. It is also possible for the user to set a predetermined number of times.

On the other hand, in the delegation mode, if the transmitter is lost, anyone can open the door using the transmitter. In order to solve this problem, it is also possible to automatically operate the transmitter lock function described later in the delegation mode. That is, when the authority delegation mode is set, the transmitter lock function is automatically set so that the transmitter can be used only by inputting a password that is already set.

<Lock transmitter>

The user can also set the sender to be unusable unless a password is entered in order to prevent unauthorized use of the sender.

A procedure of setting and releasing the transmitter lock mode will be described with reference to FIG. 11. In FIG. 11, setting and releasing of the transmitter lock mode are performed in a toggle method.

The user selects the transmitter lock menu on the screen of FIG. 7A (step S1101). Then, the control unit 120 of the transmitter 100 checks whether the transmitter 100 is currently in the lock mode (step S1103).

When the transmitter 100 is in the lock mode, the function of releasing the transmitter lock mode is selected. Therefore, the controller 120 requests the user to input a password using the display unit 123 or the voice playback unit 130. (Step S1131). When the user inputs a password (step S1133), the control unit 120 compares the password stored in the memory 131 with the input password, and confirms whether they match (step S1135). The password may be stored in the memory 131 in step S1129 or by using a separate password input function.

If the passwords match, the lock mode is released to exit the lock mode (step S1137). If the passwords do not match, an error message is issued and the process ends (step S1141).

If it is not the current lock mode in step S1103, the function of setting the lock mode is selected. To set the lock mode, if a password has already been registered, enter the password. If a password is not registered, a password must be set first.

Therefore, it is checked in step S1105 whether the current password is set. If a password is set, the control unit 120 requests the input of the password using the display unit 123 or the voice playback unit 130 (step S1107). When the user enters a password (step S1109), it is checked whether this password matches the password stored in the memory 131 (step S1111).

If they do not match, go to step S1141 to send an error message and end. If they match, the transmitter is set to the lock mode (step S1113).

If the current password is not set in step S1105, the control unit 120 requests the input of the password using the display unit 123 or the audio reproducing unit 130 (step S1127). If the user enters a password, the control unit 120 stores it in the memory 131 (step S1129), and goes to step S1113 to set the transmitter to the lock mode.

When the user selects the door open menu when the transmitter is set in the lock mode as described above, the controller 120 requests a password to be entered after step S601 of FIG. 6. If the password input by the user matches the password stored in the memory 131, the controller 120 proceeds to the process from step S603 of FIG. 6. If the passwords do not match, an error message is displayed and the door opening procedure is terminated.

While the invention has been described using some preferred embodiments, these embodiments are illustrative and not restrictive. Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the invention and the scope of the rights set forth in the appended claims.

For example, in the present specification, a system for opening and closing the door has been described, but the present invention is not limited to the door opening and closing system, and the present invention can be applied to a starting system or other security system of the vehicle as it is. Do. That is, the vehicle starting unit may be provided in place of the door lock driving unit of the receiver so that the vehicle can be started when it is recognized as a legitimate user by the fingerprint.

As described above, according to the present invention, since fingerprints are registered for each sender, the fingerprint authentication time can be shortened because the receiver can be compared with the fingerprint registered for the sender when authenticating the fingerprint.

In addition, in an emergency, since the authority to temporarily open the door can be delegated to another person whose fingerprint is not registered for the transmitter, there is an effect that it is convenient to use.

In addition, since the lock mode for using the transmitter can be provided only when a password is input to the transmitter, there is an effect that a higher level of security can be maintained.
