Description

  The present invention relates to an authentication system for performing personal authentication of a person to be authenticated using human body communication, and an information processing apparatus including an authentication device included in the authentication system.

  In personal authentication when using a personal computer or a multi-function device, password authentication that performs authentication based on a password input by a user is widely used. In this password authentication, for example, in Patent Document 1, in order to prevent a password input by another from being accidentally matched and authenticated, in addition to the matching of a character string input as a password, the input operation A technique is disclosed in which security by password authentication is enhanced by making the coincidence of the key pressing times in the authentication condition.

  In the password authentication, when the authentication device (the device body on the authentication side) is provided with a character input device, it can be used for inputting a password, so that no other input device is required, but the input operation is complicated. Also, as in the above technology, when the operation method is such that the pressing time for each key is adjusted while changing the key operation order according to the password, the operation becomes complicated and a burden is required for the user to reproduce the accurate operation. Will be forced.

  In recent years, biometric authentication using biometric information such as personal fingerprints and vein patterns as authentication information has become widespread as an authentication technique that eliminates the complexity of such operations. However, biometric authentication requires a dedicated reader (reading device) for reading biometric information, which increases the cost. Thus, password authentication and biometric authentication have advantages and disadvantages.

  Also, recently, when an authenticated person carries an external terminal storing authentication information and touches (touches) a specific part of the authentication apparatus, the authentication apparatus uses the human body of the authenticated person as a communication path. An authentication technique for communicating with an external terminal (human body communication) and identifying and authenticating a person to be authenticated based on authentication information in the external terminal has been put into practical use.

  This personal authentication using human body communication is easy to operate because it only touches a specific part, and authentication information that is confidential information is exchanged through the human body only at the time of touch. It can be said that it is a high method. However, since it does not identify whether or not the person carrying the external terminal is the identity of the person, that is, it does not require identity verification to the person who carried the external terminal, so impersonation of another person due to theft of the external terminal, etc. The operation cannot be recognized. Therefore, it is desired to improve security against such unauthorized use of external terminals.

  On the other hand, for example, in Patent Document 2, in personal authentication using human body communication, a server device connected to a network unifies authentication information of an information terminal device and a human body side communication device carried by the user. It is disclosed that security is improved against unauthorized use due to theft of a human body side communication device or authentication information by managing and rewriting authentication information periodically or when it is stolen.

  However, in the above method, there is a problem that when an external terminal (human body side communication device) or authentication information is stolen, it is illegally used until the authentication information is rewritten. In addition, in order to prevent unauthorized use of such an external terminal, a method of combining fingerprint authentication with a touch operation on a specific part is also conceivable. However, in this case, a fingerprint reader or the like is required, which increases the cost. is there.

  The present invention is intended to solve the above-described problem, and in personal authentication using human body communication, it is possible to prevent unauthorized use by others by terminal devices used for identification and authentication of authorized users.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
FIG. 1 shows a system configuration example of an authentication system (image processing system) 5 according to the first embodiment of the present invention. The authentication system 5 includes a multifunction machine 10 as an information processing apparatus (image processing apparatus) having a function of an authentication apparatus, and a terminal device 30.

  The multifunction machine 10 optically reads a document image, prints the duplicate image on a recording paper, and outputs it, and stores the scanned document image data as a file or transmits it to an information processing terminal such as a personal computer. A printer function for printing an image related to print data received from the information processing terminal on a recording sheet and outputting it, a facsimile function for transmitting and receiving image data, and the like. Furthermore, an authentication function for performing personal authentication (user authentication) for the user (user) of the multifunction machine 10 is provided.

  The terminal device 30 is used for identification / authentication of a regular / non-regular user in user authentication by the multifunction machine 10, and is configured to be portable. The terminal device 30 stores authentication information assigned to each authorized user, and is used by being carried by an authorized user corresponding to the stored authentication information. The authentication information is identification information such as a user ID (Identification).

  The multifunction machine 10 is provided with an operation panel 19 at the upper front of the apparatus main body 10a. The operation panel 19 has a display unit composed of a liquid crystal display or the like on the panel body, a touch panel provided on the surface (on the screen), a plurality of operation buttons, and a touch operation (touch operation) from the user at the time of authentication. A receiver (electrode) 27 and the like as a contact portion to be received are provided. The user can perform various operations for using the multifunction machine 10 through the operation panel 19.

  The multi-function device 10 performs user authentication based on authentication information in the terminal device 30 and a contact / non-contact change (transition) pattern caused by a contact operation received by the receiver 27. Specifically, the multifunction device 10 authenticates from the terminal device 30 when the human body touches the receiver 27 with a function (human body communication function) that communicates with the terminal device 30 that is connected using the human body that contacts the receiver 27 as a communication path. In addition to receiving information, changes in contact and non-contact with the receiver 27 of the human body are detected as a contact pattern (= Touch Pattern (TP)), and user authentication is performed based on the authentication information and the contact pattern. It has a function. In this user authentication, personal identification (user identification) is performed based on the authentication information, and identity verification (identity confirmation) is performed based on the contact pattern.

  Human body communication is a communication technology that uses a human body as a communication path to perform short-distance data communication, and there are a plurality of types such as a current method and an electric field method.

  The current method is a method of performing communication by passing a weak current (alternating current) through the human body and putting data (information) on the current. For example, data communication between both devices can be performed by simply touching an electrode of an authentication device or the like as a communication partner with a hand wearing a wristwatch type terminal device (data transmitter / receiver).

  In the electric field method, an electric field is generated in the vicinity of the human body, the dielectric body is dielectrically polarized, and the entire human body becomes a communication path covering the electric field. The electric field induced in the vicinity of the human body (the surface of the human body) In this method, data communication is performed through a communication path, and an electric field is used as a data signal medium.

  Specifically, a voltage (AC voltage) is applied to the surface of the human body by an electrode of the terminal device to generate a weak electric field (induction), the electric field spreads to the human body surface, and the human body surface is close to the electrode of the information equipment device Alternatively, the contact is induced by an electric field to generate a potential at the electrode. This is a mechanism for performing data communication by, for example, detecting a potential change in the electrode induced by the electric field fluctuation (electric field strength change) with an electric field sensor and converting it to an electric signal.

  In the electric field method, fluctuations in the electric field are detected as signals, so there is no need for the human body to be in direct contact with a communication device such as a terminal device or authentication device, and communication is established even if an insulator exists between the signal paths. To do. For example, communication is possible not only in the part where the hand (finger) or foot is in contact, but also within a range of several centimeters from the surface of the human body, and communication is possible even if clothes or shoes are interposed between the human body.

  The terminal device can be configured in various shapes that can be carried by the user, such as a card type, a wristwatch type, and a key type. For example, in the case of a card type incorporated in an employee ID card, as shown in FIG. 1, the user attaches the card type terminal device 30 to a neck strap 38 and hangs it on the neck or puts it in a pocket of clothes. You can carry it with you. When configured as a wristwatch, it can be worn on the wrist and carried.

  Further, since human body communication technology can supply power to the terminal device through the human body, it is not necessary to mount a secondary battery such as a battery in the terminal device, and it is possible to configure a terminal device that is easy to downsize and excellent in portability. it can.

  FIG. 2 is a block diagram illustrating a schematic configuration of the multifunction machine 10.

For example, the reading unit 13 forms a light source that irradiates light on a document, a line image sensor that receives the reflected light for one line in the width direction, and guides reflected light from the document to the line image sensor. In addition to an optical system including a lens and a mirror to be moved, a moving mechanism that sequentially moves the reading position in units of lines in the length direction of the document by moving the mirror and the light source is provided.

The modem 23 modulates and demodulates the digital signal so that it can be transmitted as an analog signal, and the NCU 26 is connected to a public telephone line and performs control and detection regarding outgoing and incoming calls.

  The external terminal communication unit 24 performs data communication with the terminal device 30 using the human body as a communication path. The external terminal communication unit 24 includes the receiver 27 described with reference to FIG. 1 and the above-described electric field sensor and the like when electric field type human body communication is used.

  The receiver 27 functions as an antenna (electrode) for performing human body communication, and is made of a conductive material. When electric field type human body communication is used, the surface of the receiver 27 may be covered with an insulating cover (protective cover) formed in a sheet shape with an insulating material such as synthetic resin (plastic).

User authentication is performed based on a collation result obtained by collating the detected touch pattern with collation touch pattern information stored in the multifunction machine 10. The user authentication processing unit 25 also detects a touch pattern for the receiver 27. The touch pattern may be detected by the CPU 11.

  FIG. 3 is a block diagram illustrating a schematic configuration of the terminal device 30. The terminal device 30 is configured by connecting a ROM 33, a RAM 34, a storage unit 35, a data input unit 36, a main body communication unit 37, and the like via a bus 32 to a CPU 31 that performs overall control of the operation of the terminal device 30.

  The storage unit 35 is a non-volatile memory, and stores authentication information used for user authentication. The data input unit 36 is an interface unit that inputs data stored in the storage unit 35 from the outside. The main body communication unit 37 performs data communication with the multifunction machine 10 using the human body as a communication path.

  FIG. 4 is a diagram showing a configuration of the user authentication information management table 40 in which verification information used for user authentication is registered. The user authentication information management table 40 is stored in the hard disk device 17 of the multifunction machine 10 or a non-volatile memory (not shown).

  In the user authentication information management table 40, a user name (registered user), verification authentication information, and verification touch pattern information (registered touch pattern (TP)) are registered in association with each other. In this example, the authentication information is a user ID.

  In this example, the touch pattern that can be registered is a pattern configured by the absolute time of touch / non-touch (contact / non-contact). Specifically, there are a touch pattern composed of only touch time and a touch pattern composed of a combination of touch time and non-touch time. The touch pattern information is registered as information indicating these touch patterns.

  In addition, you may make it provide permissible time with respect to the touch pattern comprised by this absolute time. For example, an allowable time (for example, 5 seconds) may be provided for each touch / non-touch, or an allowable time (for example, 10 seconds) may be provided for the entire touch pattern.

  The authorized user of the multifunction device 10 can arbitrarily determine a touch pattern that satisfies the above-described configuration conditions and input the information to the multifunction device 10 for registration. The multi-function device 10 accepts numerical input of this touch pattern information through an operation on the numeric keypad or the like of the operation panel 19, or an actual touch operation (input of authentication information) to the receiver 27 from the authorized user carrying the terminal device 30. The touch pattern is detected from the timing and time) and the input is received (details will be described later).

  Further, a touch sensor (detection unit) for inputting a touch pattern may be provided on the receiver 27 or other part of the operation panel 19, and a touch pattern may be detected from a touch operation on the touch sensor to receive an input. Further, if the touch panel is provided on the operation panel 19 as in the present embodiment, the touch panel may also be used as a touch pattern input sensor (detection unit).

  In the case of operation input, the touch pattern information input by the touch operation may be displayed and confirmed. Further, the displayed touch pattern information may be configured to be corrected (finely adjusted) by an operation such as a numeric keypad.

  In the user authentication information management table 40 of this example, for user A, for example, “12345678” is registered as the user ID, and “touch for 1 second—non-touch for 0.5 second—touch for 1 second” is registered as the touch pattern information. Registered (configuration by combination of touch time and non-touch time). In the case of the user B, “11111111” is registered as the user ID, and “3-second continuous touch” is registered as the touch pattern information (configuration based only on the touch time). The terminal device 30 carried by each authorized user stores the same user ID as the user ID registered in the multifunction machine 10.

  In addition, when the MFP 10 receives a user ID for which touch pattern information is not registered from the terminal device 30, the MFP 10 performs user authentication using only the user ID (see user D).

  Next, the operation of the authentication system 5 will be described.

  FIG. 5 is a diagram illustrating an example of a touch pattern and an authentication operation sequence performed by the authentication system 5. The outline of the authentication information (user ID) request / response sequence and the authentication method (touch pattern detection / collation method) in the authentication operation will be described with reference to FIG.

  When the MFP 10 starts the authentication operation (user authentication process), the external terminal communication unit 24 (receiver 27) requests a user ID at a constant time interval (fixed period) (P1). For example, a user ID is requested every 100 ms. When the user carrying the terminal device 30 touches the receiver 27 of the multifunction device 10, the terminal device 30 is connected to the multifunction device 10 using the user's human body as a communication path. In this connected state (touch state), when the terminal device 30 receives a request for a user ID from the multifunction device 10 (P1), the terminal device 30 transmits the stored user ID to the multifunction device 10 (P2).

  When the multifunction device 10 receives the user ID from the terminal device 30, the multifunction device 10 collates the user ID with the user ID registered in the user authentication information management table 40 (user identification). If there is no matching user ID registered, it is determined that authentication is not possible. If there is a match, only when the user ID is received for the first time (T1), the touch pattern information associated with the user ID is read and the touch pattern to be detected is collated along the touch pattern information. (Verification start).

  The touch pattern is detected based on whether or not there is a response to the user ID request being executed at regular time intervals. As described above, in this example, the touch pattern is configured by the touch / non-touch time (absolute time), and the multi-function device 10 recognizes the touch / non-touch state according to the presence / absence of the response of the user ID, and The duration is measured, and changes in each state including the duration are detected as touch patterns. The time is measured by a timer (not shown).

  Specifically, when there is no response to the request for the user ID, the multifunction device 10 recognizes that it is in a non-touch state. When the response starts, it is recognized that the non-touch state is switched to the touch state, and it is recognized that the touch state is continued while the responses are continuously provided. When the response is interrupted, it is recognized that the touch state is switched to the non-touch state, and the time from the start to the end of the response is recognized as the touch state duration (touch time). While there is no response, it is recognized that the non-touch state is continued. When the response starts again, it is recognized that the non-touch state is switched to the touch state, and the time from the end of the response to the start is recognized as the non-touch state duration (non-touch time).

  The multi-function device 10 detects the touch pattern based on the touch / non-touch state recognized in this way and the duration of the recognized (timed) state. Then, every time touch time / non-touch time is recognized (detected), collation with the touch pattern information is advanced.

  If the MFP 10 receives a user ID different from the first time in the response from the terminal device 30 for the second time or later during the verification, the multi-function device 10 determines that the authentication is impossible (identification of the person to be authenticated). If the detected touch time / non-touch time is different from the touch pattern information, it is determined that authentication is not possible (confirmation of the identity of the person to be authenticated). When the detected touch time / non-touch time (touch pattern) is collated and the touch pattern information matches to the end and the same user ID as the first time is received until the end of the collation, it is determined that the authentication is permitted ( T2).

  For example, when the multifunction device 10 receives [user ID = 1345567] (T1), the multifunction device 10 recognizes that the user A touches the receiver 27, strictly speaking, the terminal device 30 of the user A is connected (user Identification / refer to FIG. 4), [Touch pattern information = touch for 1 second−non-touch for 0.5 second−touch for 1 second] of user A is read, and detection and verification of the touch pattern proceed accordingly. When the user ID is received (when the touch state is recognized), the user ID of the user A is always received, and it can be confirmed that the detected touch pattern matches the touch pattern information of the user A to the end. (T2), it is determined that the user A has performed the touch operation (identification), and the authentication is completed.

  The duration of the touch / non-touch state may be obtained by counting the number of user ID requests executed at regular time intervals and converting from the count value instead of measuring using a timer. Good. In the touch pattern verification, a predetermined allowable range is provided for the touch pattern information, and if the detected touch pattern is within the allowable range, it is determined that they match. For example, the allowable range may be set to a time range of ± 20% of the touch time / non-touch time in the touch pattern information. In the case of this allowable range, if the touch time / non-touch time in the touch pattern information is 1 second, if the detected touch time / non-touch time is within the range of 0.8 seconds to 1.2 seconds, it is coincident to decide.

  Next, details of the authentication operation by the authentication system 5 will be described.

  FIG. 6 is a diagram illustrating a flow of user authentication processing performed by the multifunction machine 10. This processing is started automatically when the multifunction device 10 is turned on, or started when an authentication start operation (such as pressing an authentication start button) is received on the operation panel (operation unit) 19. Is done. During this processing, the CPU 11 and the CPU 11 control the display unit 18, the external terminal communication unit 24, the user authentication processing unit 25, and the like, and each unit performs each processing step described below. Further, here, the flow of successful authentication will be described in the order of touch (first time) -non-touch-touch (second time)..., And the flow of authentication failure will be the last. It will be explained collectively.

  When the MFP 10 starts the user authentication process (Start), the external terminal communication unit 24 requests a user ID at a constant cycle (a constant time interval) (step S101). The external terminal communication unit 24 repeats this request at regular intervals during this process. If no user ID is received in response to the request, the flow of Step S102; No → Step S110; No → Step S101 is repeated.

  As described above, when the user carrying the terminal device 30 touches the receiver 27 of the multifunction device 10, the terminal device 30 is connected to the multifunction device 10 using the user's human body as a communication path, and the multifunction device 10 requests the user ID. Is received, the stored user ID is transmitted to the multifunction device 10.

  When the external terminal communication unit 24 receives the user ID from the terminal device 30 (step S102; Yes [first touch]), the user authentication processing unit 25 checks the user ID for verification registered in the user authentication information management table 40. In step S103, it is determined whether or not there is a match with the received user ID. If there is no match (step S103; Yes), authentication fails and the process proceeds to step S118. If there is a match (step S103; No), it is determined whether or not the touch time is being measured (step S104). If the touch time has not been measured (step S104; No), the touch time is started, and if the non-touch time has been clocked, the clock is ended (step S105).

  Subsequently, the user authentication processing unit 25 determines whether or not the received user ID is stored in the RAM 16 (step S106). The user ID is not stored in the first reception, and the user authentication processing unit 25 determines that the user ID is not stored (step S106; No), and stores the received user ID in the RAM 16 (step S107). Then, the verification touch pattern information corresponding to the user ID is read from the user authentication information management table 40 (step S108), and the process returns to step S101.

  When the same user ID is received again in response to the next user ID request (Step S102; Yes → Step S103; No), since the touch time is being measured here (Step S104; Yes), the user authentication processing unit 25 Then, it is determined whether or not the currently measured touch time is over the touch time indicated in the collation touch pattern information (step S109). If the time is over (step S109; Yes), authentication fails and the process proceeds to step S118. If the time is not over (step S109; No), the process returns to step S101.

  If the user ID cannot be received in response to the user ID request during the touch time measurement (step S102; No [non-touch]), the user authentication processing unit 25 determines whether or not the user ID is stored in the RAM 16. Is determined (step S110). Here, the user ID is stored, and the user authentication processing unit 25 determines that it has been stored (step S110; Yes), and determines whether or not the non-touch time is being measured (step S111). . When the non-touch time is not timed (step S111; No), the time measurement of the non-touch time is started and the time measurement of the touch time is ended (step S112).

  Subsequently, the user authentication processing unit 25 determines whether or not the touch time is coincident with the touch time indicated in the collation touch pattern information (step S113). Here, a mismatch due to the touch time being too short is confirmed, and if they do not match (step S113; No), authentication fails and the process proceeds to step S118. If they match (step S113; Yes), the user authentication processing unit 25 determines whether or not this touch time is the final touch pattern information for verification (step S114).

  Note that the final timing of the touch pattern is only the timing when the touch time is determined from the touch state to the non-touch state (at the time of touch-off), and touching is performed when the reception of this user ID is stopped and the time measurement of the touch time ends. Make a final confirmation of the pattern. When the measured touch time is the final touch pattern information (step S114; Yes), it is determined that the authentication is successful (step S121), and this process ends (End). If it is not final (step S114; No), the process returns to step S101.

  If the user ID is not received again in response to the next user ID request (Step S102; No → Step S110; Yes), the non-touch time is being measured here (Step S111; Yes), so the user authentication processing unit 25 determines whether or not the non-touch time currently being counted is over the non-touch time indicated in the touch pattern information for collation (step S115). If it is time-over (step S115; Yes), authentication fails and the process proceeds to step S118. If the time is not over (step S115; No), the process returns to step S101.

  If a user ID that is not registered in the user authentication information management table 40 is received in response to the user ID request during the non-touch time measurement (step S102; Yes → step S103; Yes), the authentication fails, and the step The process proceeds to S118. When the user ID registered in the user authentication information management table 40 is received in response to the user ID request (step S102; Yes → step S103; No [second touch]), the touch time is being counted here. Since there is not (step S104; No), the user authentication processing unit 25 starts measuring the touch time and ends measuring the non-touch time (step S105).

  Subsequently, the user authentication processing unit 25 determines whether or not the received user ID matches the user ID stored in the RAM 16 (step S106; Yes → step S116). If the user IDs do not match (step S116; No), authentication fails and the process proceeds to step S118. For example, when the user is switched during the detection of the touch pattern, the authentication fails due to the identity confirmation of the user ID.

  When the user IDs match (step S116; Yes), the user authentication processing unit 25 determines whether or not the non-touch time matches the non-touch time indicated in the verification touch pattern information ( Step S117). Here, a mismatch due to the non-touch time being too short is confirmed, and if they do not match (step S117; No), authentication fails and the process proceeds to step S118. If they match (step S117; Yes), the process returns to step S101 (while the touch state is continuing).

  In the same manner, the touch time is measured, and if the touch time is over during the time measurement (step S102; Yes → Step S103; No → Step S104; Yes → Step S109; Yes), the process proceeds to Step S118. . If the user ID cannot be received during the touch time measurement, the non-touch time measurement is started and the touch time measurement is ended and collation with the touch pattern information of the touch time is performed. (Step S102; No → Step S110; Yes → Step S111; No → Step S113; No), the process proceeds to Step S118. If they match, the touch pattern is finally confirmed. If not, the process returns to step S101, and the subsequent processing steps are similarly repeated. If it is the final touch pattern, it is determined that the authentication is successful, and this process is terminated.

  When the process proceeds to step S118, the CPU 11 displays “illegal ID reception” on the display unit 18 (step S118) to notify the user that the authentication has failed. Further, the user authentication processing unit 25 determines that the authentication has failed (step S119), and if the user ID is stored in the RAM 16, deletes the user ID (step S120) and returns to step S101. After this authentication failure, when the MFP 10 receives a new user ID, it again checks the user ID itself or the touch pattern corresponding to the user ID against the user ID. Make a failure decision.

  When the authentication is successful, the multifunction machine 10 stops the user authentication process and shifts to the authentication state. When an operation is received from the user in this authentication state, various operations (job setting, execution, etc.) corresponding to the operation are performed, and when the authentication state is canceled, the user authentication process is started again. The release of the authentication state is, for example, a manual release by a user operation or an automatic release when a no-operation state is continued for a predetermined time.

  FIG. 7 is a diagram illustrating a flow of ID transmission processing performed by the terminal device 30. This process is started when the terminal device 30 is connected to the multifunction device 10 by using the user's touch operation on the receiver 27 of the multifunction device 10 as a communication path and receives power supply from the multifunction device 10.

  When the terminal device 30 starts the ID transmission process (Start), the CPU 31 monitors an ID transmission request from the multifunction device 10 (step S151: No). When receiving the ID transmission request from the multifunction device 10 (step S151: Yes), the CPU 31 transmits the user ID stored in the storage unit 35 to the multifunction device 10 through the main body communication unit 37 (step S152).

  The terminal device 30 repeatedly transmits a user ID to the multifunction device 10 every time an ID transmission request is received during connection with the multifunction device 10 in which the user's touch state is continued. When the user's touch state is released and the connection with the multifunction machine 10 is interrupted, the power supply is stopped and the process is automatically terminated.

  As described above, in the authentication system 5 according to the present embodiment, the multifunction peripheral 10 is connected to the terminal device 30 connected by using the human body touching the receiver 27 as a communication path in accordance with the touch operation of the human body (authenticated person) on the receiver 27. In addition to receiving the user ID (authentication information), the touch and non-touch changes to the receiver 27 of the human body are detected as a touch pattern. Then, user authentication is performed based on the collation result obtained by collating the received user ID with the collation user ID, and the collation result obtained by collating the detected touch pattern with the touch pattern information for collation, and the user ID and touch The authentication is successful only when the patterns match each other, and the authentication is unsuccessful otherwise.

  As a result, even if an unauthorized user or the like who has acquired the terminal device 30 uses the terminal device 30 to perform user authentication with the multifunction machine 10, the touch pattern determined by the authorized user who is the owner of the terminal device 30 is not known. Therefore, it cannot be reproduced and authentication fails. Therefore, unauthorized use of the terminal device 30 by another person can be prevented, and security in user authentication using human body communication can be improved.

  Further, since the touch pattern is composed only of the time element, and is not composed of the place (operation part) and the time element as in Patent Document 1, the touch pattern is stored and reproduced by the user. Operation is simple. That is, here, the touch location is only the receiver 27 (one location), and the authorized user remembers only one type of touch pattern consisting of the elements of the time determined by himself, and the reproduction operation is performed only on the receiver 27. Since it only has to be performed, the storage and reproduction operation of the touch pattern is simplified. Thereby, it becomes difficult for the authorized user to reproduce the operation of the touch pattern, and it is possible to prevent the authentication from failing. In addition, you may enable it to touch-operate arbitrary places, for example by enlarging the receiver 27 or providing two or more receivers 27.

  Further, when the multifunction machine 10 has a function for inputting and registering touch pattern information for collation by a touch operation, the authorized user touches the receiver 27 (or a touch sensor or the like) with a touch pattern determined by the user (touch). And non-touch), the touch pattern information for collation can be directly input and registered in the multifunction machine 10. As a result, it is possible to easily input and register the touch pattern information for verification to the multifunction device 10. Further, when the receiver 27 also receives the input operation, it is not necessary to provide a dedicated touch sensor and the configuration can be simplified.

  In addition, the multifunction device 10 detects a touch and non-touch change (touch pattern) of the person to be authenticated with respect to the receiver 27 based on a change in reception and non-reception of the user ID from the terminal device 30. Even without providing a touch sensor for directly detecting touch and non-touch on the receiver 27, a touch pattern can be detected with a simple configuration of only the receiver 27.

[Second Embodiment]
In the first embodiment, an example in which touch pattern information for verification is stored in the multifunction device 10 has been described. In the second embodiment, touch pattern information for verification is stored in the terminal device 30, and the multifunction device 10 is connected to the terminal. An example will be described in which touch pattern information is received from the device 30 and a touch pattern matching determination is performed.

  In the authentication system 5 of the present embodiment, the terminal device 30 stores the user ID (authentication information) of the authorized user carrying the terminal device 30 and the touch pattern determined by the authorized user in the storage unit 35 described in FIG. Touch pattern information to be shown is stored. The touch pattern information is input to the terminal device 30 through the data input unit 36. The terminal device 30 is configured to transmit the stored user ID and touch pattern information when connected to the multifunction device 10 and receiving an ID transmission request.

  Assume that only the user name (registered user) and the user ID for collation are registered in the MFP 10 in the user authentication information management table 40 described with reference to FIG. When the terminal device 30 is connected, the multifunction device 10 receives the user ID and touch pattern information received in response to the ID transmission request to the terminal device 30 and the user registered in the user authentication information management table 40. The user authentication is performed based on the collation result with the touch pattern detected from the touch operation on the ID and the receiver 27.

  FIG. 8 is a diagram illustrating a flow of user authentication processing performed by the multifunction machine 10 according to the second embodiment. FIG. 9 is a diagram illustrating a flow of ID / touch pattern transmission processing performed by the terminal device 30 according to the second embodiment.

  Here, processing by the terminal device 30 will be described first. The start and end timings of this process are the same as in the first embodiment in that the user carrying the terminal device 30 touches the receiver 27 of the multi-function device 10 (power supply starts by connection with the multi-function device 10) and non- This is the timing of touch (power supply stoppage due to disconnection from the multifunction device 10).

  When the terminal device 30 starts this processing (Start), the CPU 31 monitors an ID transmission request from the multifunction machine 10 (step S251: No). When receiving the ID transmission request from the multifunction device 10 (step S251: Yes), the CPU 31 transmits the user ID and touch pattern information stored in the storage unit 35 to the multifunction device 10 through the main body communication unit 37 (step S252). . The terminal device 30 repeatedly transmits a user ID and touch pattern information to the multifunction device 10 every time an ID transmission request is received during connection with the multifunction device 10 in which the user's touch operation is continued.

  The user authentication processing by the multifunction machine 10 differs from the first embodiment in that the user ID and touch pattern information received from the terminal device 30 are stored in the RAM 16 (step S208), and the touch pattern is detected from the touch operation on the receiver 27. Are compared with the touch pattern information, and when authentication fails, the user ID and the touch pattern information stored in the RAM 16 are deleted (step S220). Other processing steps are the same as those in the first embodiment.

  Thereby, similarly to the first embodiment, the authentication system 5 of the present embodiment can also prevent unauthorized use of the terminal device 30 by others, and can improve security in user authentication using human body communication. .

  In this embodiment, each time the terminal device 30 receives an ID transmission request, the terminal device 30 transmits the user ID and touch pattern information. However, the touch pattern information may be transmitted intermittently. For example, after connecting to the multifunction device 10, the user ID and touch pattern information may be transmitted only for the first time, and only the user ID may be transmitted for the second time and thereafter.

[Third Embodiment]
The third embodiment is a modification of the second embodiment, and is an example in which the terminal device 30 performs a touch pattern collation determination. Specifically, the multifunction device 10 transmits information on the detected touch pattern (detected touch pattern information) to the terminal device 30 to request verification, and the terminal device 30 stores the received detected touch pattern information in the stored touch. By comparing with the pattern information and transmitting the result to the multifunction device 10, the multifunction device 10 finally determines the result of the user authentication.

  In the authentication system 5 of the present embodiment, the terminal device 30 stores the user ID (authentication information) of the authorized user who carries the terminal device 30 and the touch determined by the authorized user in the storage unit 35 as in the second embodiment. Touch pattern information (touch pattern information for verification) indicating a pattern is stored. When the terminal device 30 is connected to the multifunction device 10 and receives an ID transmission request, the terminal device 30 transmits only the stored user ID. When the terminal device 30 receives the detected touch pattern information and its matching request, the terminal device 30 detects the detected touch pattern. The information is collated with the touch pattern information stored in the storage unit 35, and the collation result is transmitted to the multifunction device 10.

  Assume that only the user name (registered user) and the user ID for verification are registered in the user authentication information management table 40 as in the second embodiment. In addition, when the terminal device 30 is connected, the multi-function device 10 detects the collation result obtained by collating the user ID received in response to the ID transmission request for the terminal device 30 with the registered user ID and the touch operation on the receiver 27. The user authentication is performed based on the verification result received in response to the touch pattern verification request.

  FIG. 10 is a diagram illustrating a flow of user authentication processing performed by the multifunction peripheral 10 according to the third embodiment.

  In the user authentication process of the present embodiment, the multifunction machine 10 (user authentication processing unit 25) receives a touch operation for authentication from the user carrying the terminal device 30 with the receiver 27, and the user ID received from the terminal device 30 is registered. If so, detection of the touch pattern is started. During detection, the confirmation that the touch time / non-touch time does not exceed the allowable time, the collation confirmation for the user ID received in the response from the terminal device 30 for the second time or later, and the identity of the user ID received for the first time Check. If there is no problem in these confirmations and an end operation (such as pressing an end button or a confirmation button) is received from the user, the detected touch pattern is confirmed. Finally, the terminal device 30 is connected again by receiving a touch on the receiver 27 from the user, and the terminal device 30 is requested to collate the detected touch pattern information, and the result is received and finally the user authentication is performed. Judge the result.

  Specifically, when receiving a user ID corresponding to the user ID registered in the user authentication information management table 40 from the terminal device 30 (step S303; No), the multifunction machine 10 starts detecting a touch pattern (step S303). In step S305 / step S311), during the measurement of the touch time / non-touch time, if the allowable time (for example, 5 seconds) is exceeded, it is determined that the time is over (step S308; Yes / step S314; Yes). For the user ID received at the time of the response from the terminal device 30 for the second and subsequent times, collation confirmation (step S303) and identity confirmation with the user ID received for the first time (step S315) are performed.

  During the touch pattern detection, when the touch time / non-touch time is finished (step S305 / step S311), the time is stored in the RAM 16 (step S312 / step S316). Further, every time the time measurement of the touch time is finished and stored (step S311 → step S312 / non-touch state at this time), the end of the touch operation is confirmed (step S313). When the end operation is received (step S313; Yes), the detected touch pattern is confirmed (step S320), and the touch time / non-touch time stored in the RAM 16 are connected in the detection order (save order). Create touch pattern information.

  When the multifunction device 10 finally receives a touch on the receiver 27 that is an operation (authentication final operation) for confirming the touch pattern collation from the user (step S321), the multifunction device 10 sends the detected touch pattern information and the collation request to the terminal device 30. (Step S322), and the collation result is received from the terminal device 30 (step S323). If the collation result does not match (step S324; No), it is determined that the authentication has failed (step S318). If the collation matches (step S324; Yes), the authentication is determined to be successful (step S325).

  FIG. 11 is a diagram illustrating a flow of ID / touch pattern matching result transmission processing performed by the terminal device 30 according to the third embodiment.

  When the terminal device 30 starts this processing (Start), the CPU 31 monitors the ID transmission request from the multifunction device 10 (step S351: No.), and also detects the detected touch pattern information and the matching request from the multifunction device 10. (Step S352: No).

  When receiving the ID transmission request from the multifunction device 10 (step S351: Yes), the CPU 31 transmits the user ID stored in the storage unit 35 to the multifunction device 10 through the main body communication unit 37 (step S353).

  When the detected touch pattern information and the matching request are received from the multifunction device 10 (step S352: Yes), the CPU 31 compares the received detected touch pattern information with the touch pattern information stored in the storage unit 35 (step S354). . In the case of collation match, the CPU 31 transmits the collation result to the multifunction machine 10 through the main body communication unit 37. If the verification does not match, the CPU 31 transmits the verification result to the multifunction machine 10 through the main body communication unit 37 (step S355).

  Thereby, similarly to the first and second embodiments, the authentication system 5 of the present embodiment can also prevent unauthorized use of the terminal device 30 by others and improve security in user authentication using human body communication. be able to.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiment, and the present invention can be changed or added without departing from the scope of the present invention. Included in the invention.

  For example, the touch pattern (contact pattern) is a pattern constituted by the absolute time of touch / non-touch (contact / non-contact), or a pattern constituted by the relative time (time ratio) of touch / non-touch. May be.

  The input of touch pattern information for verification to the multifunction device may be input from the outside in addition to the direct input to the multifunction device. For example, a touch pattern input / storage device including a touch sensor, a data storage unit, a connection unit (communication unit), and the like may be configured, and touch pattern information may be input to the multifunction peripheral via this device. . That is, the touch pattern information input by the touch operation on the touch sensor is stored in the data storage unit, and the touch pattern information is transmitted to the multi-function device 10 when connected to the multi-function device 10. An input from the outside may be made to the multifunction device.

  The touch pattern detection in the multifunction device is performed based on the response from the terminal device 30 to the ID transmission request (user ID reception / non-reception timing and duration). Not limited to this. For example, a touch sensor may be provided on the receiver, and the touch pattern may be detected by directly detecting the touch / non-touch state of the receiver and its duration with the touch sensor.

  In the third embodiment, the end of the touch operation by the person to be authenticated is recognized by the end operation received from the person to be authenticated. This is the same in the user authentication processing in the first and second embodiments. You may make it carry out. In the first and second embodiments, it is determined that the authentication is successful when the detected touch pattern matches, but the authentication target may continue the touch operation. By providing the accuracy of the touch pattern verification can be improved. Also, instead of such an ending operation, after the touch pattern detected matches and matches, it continues to detect the touch pattern for a certain time (several seconds), and after confirming that the next touch is not received It may be determined that the authentication is successful.

  In the embodiment, the terminal device according to the present invention is operated by receiving power supply from the multi-function device 10 via the human body during contact with the receiver 27. However, a battery built in the terminal device is used. It may be configured to operate as a power source.

Can do. The authentication system according to the present invention is not limited to the authentication of the information processing apparatus described in the embodiment, and can be applied to an authentication system that performs authentication such as door unlocking.
