In addition, the combination of the RFID technology and the biometric authentication technology has precedents such as mounting a biometric authentication template on the IC card, but the combination with the biometric authentication technology in the area of the RFID tag is left as a future problem. ing.

  For example, Japanese Unexamined Patent Application Publication No. 2007-257574 (Patent Document 1) describes a wireless authentication system including a biometric authentication system that performs fingerprint authentication and a wireless authentication system that uses an RFID tag.

  By the way, when the RFID tag employed in the wireless authentication system (hereinafter referred to as “conventional authentication system”) described in Japanese Patent Application Laid-Open No. 2007-257574 is an active type, this conventional authentication system is used. Corresponds to the prior art that combines an active RFID tag and fingerprint authentication technology. According to this conventional authentication system, since personal authentication is performed by fingerprint authentication, the security level can be increased. However, the following problems and issues can be pointed out.

  That is, in order for the user to authenticate himself / herself by fingerprint authentication, the user must approach the receiving device and touch a designated place (fingerprint authentication sensor portion) on the receiving device side. This significantly impairs the convenience of the active RFID that can perform ID authentication without approaching the receiving device.

  Further, since the fingerprint authentication part is confined on the receiving device side, it is necessary to register fingerprint information (fingerprint authentication server function) of all users on the receiving device side. As a result, when there are a large number of users to be registered, the system load on the receiving apparatus side becomes extremely heavy, such as guaranteeing a quick response to a request for fingerprint authentication, managing and updating fingerprint information (template), and the like.

  In addition, there is a problem that a user of a conventional authentication system has to entrust his own fingerprint information template, which is extremely important personal information, to the receiving apparatus side system and cannot manage it.

  Further, since the wireless transmitter (active RFID) used in the conventional authentication system does not have a transmission control means, it is impossible to start the transmission and control the transmission duration. As a result, it is difficult to meet the demands of various receiver-side systems, and the power consumption of the on-board power source for driving the active RFID cannot be saved.

  Further, the transmission duration time of the device ID required by the application on the receiving device side varies depending on the application (management target, mode, etc.). In the conventional authentication system, since the transmission duration time cannot be controlled on the RFID tag side, the reception processing of the device ID that is always transmitted from the RFID tag (for example, the processing for setting the reception timing at an appropriate interval or the like) , Processing for ignoring the device ID transmitted outside the reception timing, etc.), and as a result, the system load on the receiving device side becomes heavy.

  The present invention has been made in view of the above-described problems, for example, and a first object of the present invention is to improve the security level that does not allow unauthorized use due to loss, theft, etc. An object of the present invention is to provide an ID signal transmission device capable of fully exhibiting the convenience of active RFID that can perform ID authentication without approaching.

  The second problem of the present invention is that an ID signal that can reduce the load on the receiving device side system by performing biometric authentication on the transmitting device side, or the user can manage his / her own biometric information by himself / herself. It is to provide a transmission device.

  The third problem of the present invention is that it is possible to meet the requirements of various receiving device side systems by controlling the transmission start or the transmission continuation time, can extend the battery life of the ID signal transmission device, or An object of the present invention is to provide an ID signal transmission device capable of reducing the load on the receiving device side system.

In the conventional authentication system described above, since the receiving apparatus side system performs fingerprint authentication, the load on the receiving apparatus side system is heavy. However, according to the first ID signal transmission apparatus of the present invention, the receiving apparatus side system is fingerprint authentication. Therefore, it is possible to reduce the load on the receiving apparatus side system.

  In addition, the first ID signal transmission device of the present invention includes a second storage unit that stores a template of biological information, a biological information detected by the biological information detection unit, and a template stored in the second storage unit.

Can be changed. Therefore, according to the second ID signal transmission device of the present invention, it is possible to meet various requests (reception targets, modes, etc.) of the receiving device side system.

  The above-described third ID signal transmission device of the present invention generates an ID signal for transmitting two ID signals of a device ID and a user ID, and transmits this ID signal. Thereby, the ID signal transmission device can make the ID signal reception device recognize the ID signal transmission device that has transmitted the ID signal and the user of the ID signal transmission device based on the ID signal.

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

(Server computer access management system)
FIG. 1 shows a server computer access management system including an ID signal transmission device according to an embodiment of the present invention. As shown in FIG. 1, a server computer access management system 100 includes an ID signal transmission device 1, an ID signal reception device 2, a management device 3, and a server computer 4 that is a managed device.

  The server computer access management system 100 determines whether or not the user who wants to access the server computer 4 is a registered user, fingerprint authentication, a device ID unique to the ID signal transmission device 1, and a user-specific usage. A system that permits access to the server computer 4 by the user only when it is determined that the user who attempts to access the server computer 4 is a registered user, based on the user ID It is.

  More specifically, the ID signal transmission device 1 is a small and lightweight wireless communication device that can be carried by a user, for example, a fingerprint authentication unit that detects and collates fingerprint information of a user, and an active Type RFID module. The active RFID module is driven by power supplied from a battery, and transmits an ID signal modulated by a device ID unique to the ID signal transmission device 1 and a user ID unique to the user. The transmission distance of the ID signal is, for example, 7 meters or more. Therefore, the user who carries the ID signal transmission device 1 can cause the ID signal reception device 2 to receive the ID signal from a place that is 7 meters or more away from the ID signal reception device 2.

  In the ID signal transmission device 1, since the battery and the active RFID module are normally disconnected, the transmission of the ID signal from the ID signal transmission device 1 is stopped. However, when the user who tries to access the server computer 4 is determined to be a registered user by the fingerprint authentication means, the battery and the active RFID module are connected. The transmission of the ID signal by the ID signal transmission device 1 starts. The transmission of the ID signal continues after the transmission of the ID signal starts in this way until the transmission continuation time preset by the administrator elapses. And when transmission continuation time passes after transmission of ID signal starts, between a battery and an active RFID module is interrupted | blocked, and transmission of ID signal by ID signal transmission device 1 stops again by this.

  On the other hand, the ID signal receiving device 2 receives the ID signal transmitted from the ID signal transmitting device 1 and sends the device ID and the user ID included in the ID signal to the management device 3. Then, the management device 3 receives the device ID and user ID sent from the ID signal receiving device 2, and collates them with the device ID and user ID stored in the management device 3, respectively. Then, the management device 3 matches the device ID received from the ID signal receiving device 2 with the device ID stored in the management device 3 and stores the user ID received from the ID signal receiving device 2 in the management device 3. When the obtained user ID matches, the user is permitted to access the server computer 4. As a result, the user can access the server computer 4. As will be described later, in the management device 3, it is also possible to set an access permission range for the server computer 4 by the user.

  In addition, before performing such transmission / reception of the ID signal between the ID signal transmission device 1 and the ID signal reception device 2 and ID collation by the management device 3, the setup of the ID signal transmission device 1 and the management device 3 is performed. It is necessary to perform processing. The contents of the setup process are (1) reading the device ID from the ID signal transmission device 1 and storing the device ID in the management device 3, and (2) storing the user's fingerprint information template in the ID signal transmission device 1. (3) storing the user ID in the ID signal transmission device 1 and the management device 3, respectively, and (4) storing the transmission duration information in the ID signal transmission device 1.

  The storage unit 21 is a read-only nonvolatile storage element such as a ROM (Read Only Memory). A device ID 24 is stored in the storage unit 21 in advance. The device ID 24 is identification information for identifying the ID signal transmission device 1, and is a numerical value unique to the ID signal transmission device 1, for example.

  The ID signal generation unit 22 IDs the device ID 24 stored in the storage unit 21 and any one of the user IDs 28A, 28B, and 28C stored in the storage unit 25 of the fingerprint authentication module 14. An ID signal to be transmitted to the signal receiving device 2 is generated.

  Specifically, the ID signal generation unit 22 generates a composite ID by adding any one of the user IDs 28A, 28B, and 28C to the device ID 24, and is modulated by the composite ID. An ID signal that is a high-frequency signal is generated, and this ID signal is supplied to the transmission antenna 23. The ID signal generator 22 includes a high-frequency transmission circuit, an arithmetic processing circuit, and the like.

  The transmission antenna 23 is an antenna for transmitting the ID signal generated by the ID signal generation unit 22.

  On the other hand, the fingerprint detection unit 13 detects fingerprint information from the user's finger. The fingerprint detection unit 13 is, for example, a capacitance type, thermal type, RF electrolysis detection type, or optical scanning type fingerprint sensor. For example, as shown in FIG. 3, the fingerprint detection unit 13 is disposed on the outer surface of the casing 19 of the ID signal transmission device 1. When the user places his / her finger on the fingerprint detection unit 13, the fingerprint detection unit 13 detects the fingerprint information of the user. The fingerprint detection unit 13 is a specific example of biometric authentication means together with the fingerprint authentication module 14.

  The fingerprint authentication module 14 includes a storage unit 25 and a fingerprint collation unit 26.

  The storage unit 25 is a rewritable nonvolatile storage element such as a flash memory. The storage unit 25 stores a plurality of templates 27A, 27B, and 27C and a plurality of user IDs 28A, 28B, and 28C. Templates 27A, 27B, and 27C are templates of fingerprint information of users A, B, and C, respectively. The user IDs 28A, 28B, and 28C are identification information for causing the management device 3 to identify the user of the ID signal transmission device 1. For example, the user IDs 28A, 28B, and 28C are unique numerical values assigned to the users A, B, and C, respectively. The templates 27A, 27B, and 27C and the user IDs 28A, 28B, and 28C are stored in the storage unit 25 in an associated state. The operation of storing the templates 27A, 27B, 27C and the user IDs 28A, 28B, 28C in the storage unit 25 is performed by the administrator of the server computer access management system 100 in the setup process of the ID signal transmission device 1.

  The fingerprint collation unit 26 collates the fingerprint information detected by the fingerprint detection unit 13 with the templates 27A, 27B, and 27C stored in the storage unit 25.

  Specifically, the fingerprint collation unit 26 receives the fingerprint information detected by the fingerprint detection unit 13 from the fingerprint detection unit 13, and extracts and transforms the detected fingerprint information into a template format as necessary. Then, the fingerprint collation unit 26 sequentially compares the fingerprint information with the templates 27A, 27B, and 27C stored in the storage unit 25, and selects a template that matches the detected fingerprint information with the templates 27A, 27B, and 27C. Find out from inside. Subsequently, when a template that matches the detected fingerprint information is found, the fingerprint collation unit 26 sends a match signal indicating that a template that matches the detected fingerprint information has been found. To the unit 29. If a template that matches the detected fingerprint information is found, the fingerprint collation unit 26 uses the user ID associated with the template that matches the detected fingerprint information stored in the storage unit 25. The user ID is selected from the user IDs 28A, 28B, and 28C, and the selected user ID is sent to the ID signal generation unit 22 of the active RFID module 12. This user ID is sent from the storage unit 25 to the ID signal generation unit 22 of the active RFID module 12 via the general control unit 18, for example.

  The fingerprint collation unit 26 includes, for example, an arithmetic processing circuit, a ROM, a RAM (Random Access Memory), and the like.

  The transmission control module 15 includes a transmission control unit 29 and a storage unit 30.

  The transmission control unit 29 controls the start and stop of transmission of the ID signal by the active RFID module 12.

  That is, the transmission control unit 29 determines the fingerprint information detected by the fingerprint detection unit 13 as a result of the collation by the fingerprint collation unit 26 of the fingerprint authentication module 14 and the templates 27A and 27B stored in the storage unit 25 of the fingerprint authentication module 14. , 27C, the transmission of the ID signal is started when one of the templates matches.

  Specifically, the transmission control unit 29 receives a power switch control signal for turning on the power switch 16 when receiving a match signal output from the fingerprint collation unit 26 of the fingerprint authentication module 14. Supply to the control terminal. The power switch 16 is a switch that is provided between the battery 11 and the active RFID module 12 and switches connection and disconnection between the battery 11 and the active RFID module 12. The power switch 16 has a control terminal, and the power switch 16 is turned on while a power switch control signal is supplied to the control terminal. When the power switch 16 is turned on, the battery 11 and the active RFID module 12 are connected, and power is supplied from the battery 11 to the active RFID module 12. Thereby, the ID signal is transmitted by the active RFID module 12.

  Further, the transmission control unit 29 recognizes the transmission duration time of the ID signal by referring to the transmission duration time information 31 stored in the storage unit 30 of the transmission control module 15 and starts transmission of the ID signal after starting transmission of the ID signal. When the duration time has elapsed, the transmission of the ID signal is stopped.

  Specifically, immediately after supplying the power switch control signal to the power switch 16, the transmission control unit 29 reads the transmission duration information 31 stored in the storage unit 30 of the transmission control module 15 and sends it to the transmission control unit 29. Timekeeping is started by a built-in timer (not shown). Then, the transmission control unit 29 compares the timer value with the transmission duration information 31, and when the timer value matches the transmission duration information 31, the transmission control unit 29 stops the time measurement by the timer and supplies the power of the power switch control signal. Supply to the switch 16 is stopped. As a result, the power switch 16 is turned off, the battery 11 and the active RFID module 12 are cut off, and the power supply from the battery 11 to the active RFID module 12 is stopped. Thereby, transmission of the ID signal by the active RFID module 12 is stopped.

  The transmission control unit 29 includes, for example, an arithmetic processing circuit, a timer, a ROM, a RAM, and the like.

  The storage unit 30 is a rewritable nonvolatile storage element such as a flash memory. The storage unit 30 stores transmission duration information 31 indicating the duration of ID signal transmission by the active RFID module 12. The transmission duration information 31 is a numerical value indicating the transmission duration of the ID signal, for example. The administrator of the server computer access management system 100 can set an arbitrary transmission duration from about 1 second to unlimited by setting and changing the transmission duration information 31 in the setup process of the ID signal transmission device 1. Can be set.

A read control signal is supplied to 21, the device ID 24 stored in the storage unit 21 is read, and this device ID 24 is sent to the management device 3. This device ID 24 is stored in the management device 3. Note that a method different from this may be adopted as a method of registering the device ID 24 in the management device. For example, after a fingerprint information template is registered in the ID signal transmission device 1, fingerprint authentication is performed in the ID signal transmission device 1, and thereby the device ID 24 transmitted from the ID signal transmission device 1 is transmitted via the ID signal reception device 2. Alternatively, a method may be employed in which the data is taken into the management device 3 and stored in the management device 3.

  In addition, the general control unit 18 performs a remote operation sent from the management device 3 when registering or changing the fingerprint information template of the user for the ID signal transmission device 1 in the setup process of the ID signal transmission device 1. In accordance with the signal, a write control signal is supplied to the storage unit 25 of the fingerprint authentication module 14. When the user puts his / her finger on the fingerprint detection unit 13 with the write control signal supplied to the storage unit 25, the fingerprint information of the user is detected, and the detected fingerprint information is written in the storage unit 25 as a template.

  In addition, the general control unit 18 performs a fingerprint according to a remote operation signal sent from the management device 3 when registering or changing the user ID for the ID signal transmission device 1 in the setup process of the ID signal transmission device 1. A write control signal is supplied to the storage unit 25 of the authentication module 14 and a user ID sent from the management apparatus 3 is input to the storage unit 25 of the fingerprint authentication module 14. Thereby, the user ID sent from the management device 3 is written in the storage unit 25. Further, in the setup processing of the ID signal transmission device 1, when deleting the user ID stored in the storage unit 25 of the fingerprint authentication module 14, the storage of the fingerprint authentication module 14 is performed according to the remote operation signal sent from the management device 3. A delete control signal is supplied to the unit 25. As a result, the user ID stored in the storage unit 25 is deleted.

  In addition, the overall control unit 18 sets up or changes the transmission duration information for the ID signal transmission device 1 in the setup process of the ID signal transmission device 1 according to the remote operation signal sent from the management device 3. While supplying a light control signal to the memory | storage part 30 of the transmission control module 15, the transmission duration information sent from the management apparatus 3 is input into the memory | storage part 30 of the transmission control module 15.

The registration communication interface 61 includes, for example, a USB interface circuit and a USB terminal.

  The administrator access management unit 62 restricts the persons who can access the management apparatus 3 in order to perform setup processing of the ID signal transmission apparatus 1 and the management apparatus 3 to only administrators of the server computer access management system 100. Therefore, fingerprint authentication of the administrator is performed.

  This fingerprint authentication is performed by the following procedure, for example. First, the ID signal transmission device 1 is connected to the management device 3 using, for example, a USB cable, and the fingerprint information of the administrator is detected by the fingerprint detection unit 13 of the ID signal transmission device 1. The administrator's fingerprint information detected by the fingerprint detection unit 13 is transferred from the fingerprint detection unit 13 of the ID signal transmission device 1 to the management device 3.

The transferred fingerprint information of the administrator is a template of the fingerprint information of the administrator stored in the storage unit 52 by a fingerprint collation unit (not shown) provided in the administrator access management unit 62 of the management device 3. If the two are matched, the administrator is allowed to access the management device 3.

  The remote operation unit 63 remotely operates the ID signal transmission device 1 in the setup process of the ID signal transmission device 1 and the management device 3.

  Specifically, when the remote operation unit 63 reads the device ID 24 from the ID signal transmission device 1 in the setup process of the management device 3, the remote operation unit 63 stores the storage unit 21 of the active RFID module 12 of the ID signal transmission device 1. A remote operation signal for performing read control is sent, the device ID 24 is read from the storage unit 21, and the device ID 24 is stored in the storage unit 52 of the management device 3.

  In addition, the remote operation unit 63 performs fingerprint authentication of the ID signal transmission device 1 when registering or changing the template of the fingerprint information of the user for the ID signal transmission device 1 in the setup process of the ID signal transmission device 1. A remote operation signal for performing write control of the storage unit 25 of the module 14 is sent to the ID signal transmission device 1.

The remote operation signal for performing the light control of the unit 25 and the user ID input by the administrator operating the operation unit 64 are sent to the ID signal transmission device 1. Further, when deleting the user ID stored in the storage unit 25 of the fingerprint authentication module 14 of the ID signal transmission device 1, delete control of the storage unit 25 of the fingerprint authentication module 14 of the ID signal transmission device 1 is performed. A remote operation signal is sent to the ID signal transmission device 1.

  Further, the remote operation unit 63 sets the transmission duration information for the ID signal transmission device 1 in the setup process of the ID signal transmission device 1, so that the transmission control module 15 of the ID signal transmission device 1 The remote operation signal for performing the light control of the storage unit 30 and the transmission duration information input by the administrator operating the operation unit 64 are sent to the ID signal transmission device 1.

  On the other hand, the third section 70 of the management device 3 includes components for performing general or comprehensive control of the management device 3. That is, the section 70 includes an operation unit 64, a display unit 65, and a general control unit 66.

  The operation unit 64 is an input device for an administrator to input information and commands such as a user ID and transmission duration information to the management device 3 in order to perform setup processing of the ID signal transmission device 1 and the management device 3. For example, keyboard and mouse. The operation unit 64 is also an input device used when a registered user accesses the server computer 4.

  The display unit 65 is a display device that displays various information related to the management device 3 or the server computer 4, and is a liquid crystal display, for example.

  The comprehensive control unit 66 comprehensively controls the management device 3 and includes, for example, a CPU, a ROM, and a RAM.

(Setup process)
The setup process of the ID signal transmission device 1 and the management device 3 is performed by the following procedure, for example. First, an administrator of the server computer access management system 100 connects the ID signal transmission device 1 and the management device 3 using, for example, a USB cable.

  Subsequently, the administrator causes the management apparatus 3 to authenticate his / her fingerprint in order to access the management apparatus 3. That is, the administrator places a finger on the fingerprint detection unit 13 of the ID signal transmission device 1 and causes the fingerprint detection unit 13 to detect the fingerprint information of the administrator. The administrator's fingerprint information detected by the fingerprint detection unit 13 is sent from the ID signal transmission device 1 to the management device 3 via the USB cable. As described above, the manager access management unit 62 of the management apparatus 3 performs fingerprint authentication on the fingerprint information of the manager. When the administrator's fingerprint information is correctly authenticated, access to the management apparatus 3 by the administrator is permitted.

  Subsequently, the administrator registers the device ID 24 of the ID signal transmission device 1 in the management device 3. That is, the administrator operates the operation unit 64 of the management device 3 and inputs a command to the management device 3 to register the device ID 24 of the ID signal transmission device 1 in the management device 3. In response to this, the remote operation unit 63 of the management device 3 sends a remote operation signal for performing read control of the storage unit 21 of the active RFID module 12 of the ID signal transmission device 1 to the ID signal transmission device 1 to store the storage unit. The device ID 24 is read from 21, and the device ID 24 is stored in the storage unit 52 of the management device 3.

  Subsequently, the administrator registers a template of the user's fingerprint information in the ID signal transmission device 1. That is, the administrator operates the operation unit 64 of the management apparatus 3 and inputs a command to the management apparatus 3 to register the user's fingerprint information template in the ID signal transmission apparatus 1. In response to this, the remote operation unit 63 of the management device 3 sends a remote operation signal for performing write control of the storage unit 25 of the fingerprint authentication module 14 of the ID signal transmission device 1 to the ID signal transmission device 1. When the user puts his / her finger on the fingerprint detection unit 13 with the write control signal supplied to the storage unit 25, the fingerprint information of the user is detected, and the detected fingerprint information is written in the storage unit 25 as a template. It is.

  Subsequently, the administrator registers the user ID in the ID signal transmission device 1 and the management device 3, respectively. That is, the administrator operates the operation unit 64 of the management device 3 to input a user ID and a command for registering the user ID in the ID signal transmission device 1 and the management device 3 to the management device 3. . In response to this, the remote operation unit 63 of the management device 3 receives the remote operation signal for performing the light control of the storage unit 25 of the fingerprint authentication module 14 of the ID signal transmission device 1 and the user ID input by the administrator. Is sent to the ID signal transmission device 1. As a result, the user ID input by the administrator is written in the storage unit 25 of the fingerprint authentication module 14 of the ID signal transmission device 1. On the other hand, the user ID input by the administrator is also written in the storage unit 52 of the management device 3.

  Subsequently, the administrator sets the transmission duration information in the ID signal transmission device 1. That is, the administrator operates the operation unit 64 of the management device 3 to input the transmission duration information and a command for setting the transmission duration information in the ID signal transmission device 1 to the management device 3. In response to this, the remote operation unit 63 of the management device 3 performs the remote operation signal for performing the light control of the storage unit 30 of the transmission control module 15 of the ID signal transmission device 1 and the transmission duration information input by the administrator. Are sent to the ID signal transmission device 1. As a result, the transmission duration information input by the administrator is written into the storage unit 30 of the transmission control module 15 of the ID signal transmission device 1.

(ID signal transmission processing)
FIG. 5 shows ID signal transmission processing by the ID signal transmission device 1. The ID signal transmission process is a process of transmitting an ID signal from the ID signal transmission device 1 to the ID signal reception device 2.

  As shown in FIG. 5, when the user places his / her finger on the fingerprint detection unit 13 of the ID signal transmission device 1 (step S1: YES), the fingerprint detection unit 13 detects the fingerprint information of the user (step S2).

  Subsequently, the fingerprint collation unit 26 of the fingerprint authentication module 14 collates the fingerprint information detected by the fingerprint detection unit 13 with the templates 27A, 27B, and 27C stored in the storage unit 25 of the fingerprint authentication module 14 (step) S3).

  When the fingerprint information detected by the fingerprint detection unit 13 matches one of the templates 27A, 27B, and 27C stored in the storage unit 25 (step S4: YES), the fingerprint verification unit 26 Outputs a coincidence signal (step S5).

  Further, the fingerprint collation unit 26 selects a user ID associated with the template that matches the detected fingerprint information from the user IDs 28A, 28B, and 28C stored in the storage unit 25, and this user ID. Is sent to the ID signal generator 22 of the active RFID module 12 (step S6).

  Subsequently, the transmission control unit 29 of the transmission control module 15 receives the coincidence signal output from the fingerprint verification unit 26 of the fingerprint authentication module 14 and supplies a power switch control signal to the control terminal of the power switch 16 (step S7). .

  Subsequently, the transmission control unit 29 reads the transmission continuation time information 31 stored in the storage unit 30 of the transmission control module 15 and starts measuring time by a timer built in the transmission control unit 29 (step S8).

  In step S7, when the power switch control signal is supplied to the control terminal of the power switch 16, the battery 11 and the active RFID module 12 are connected, and power is supplied from the battery 11 to the active RFID module 12. Then, the active RFID module 12 starts driving.

  When the active RFID module 12 starts driving, the ID signal generation unit 22 of the active RFID module 12 reads the device ID 24 stored in the storage unit 21 of the active RFID module 12, and stores the device ID 24 in the device ID 24 in step S6. The user ID sent from the fingerprint collation unit 26 is added, thereby generating a composite ID. Then, the ID signal generation unit 22 generates an ID signal that is a high-frequency signal modulated by the composite ID, and supplies the ID signal to the transmission antenna 23. Thereby, transmission of the ID signal by the active RFID module 12 starts (step S9).

  Subsequently, the transmission control unit 29 compares the timer value with the transmission duration information 31 and, when the timer value matches the transmission duration information 31 (step S10: YES), stops the time measurement by the timer. Then, the supply of the power switch control signal to the power switch 16 is stopped (step S11). Thereby, the battery 11 and the active RFID module 12 are disconnected from each other, the power supply from the battery 11 to the active RFID module 12 is stopped, and the active RFID module 12 stops driving. That is, the transmission of the ID signal by the active RFID module 12 is stopped.

  In step S <b> 9, the ID signal transmitted from the ID signal transmission device 1 is received by the ID signal reception device 2. The ID signal receiving device 2 sends the device ID 24 included in the received ID signal and the user ID 28A, 28B or 28C to the management device 3. The management device 3 receives the device ID 24 and the user ID 28A, 28B or 28C sent from the ID signal receiving device 2, and receives the received device ID 24 and the user ID 28A, 28B or 28C of the management device 3. The device ID 56 and the user IDs 57A, 57B, and 57C stored in the storage unit 52 are collated. Then, the management device 3 matches the received device ID 24 with the device ID 56 stored in the storage unit 52, and the received user IDs 28A, 28B or 28C and the user IDs 57A, 57B stored in the storage unit 52, When any one of the user IDs of 57C matches, access to the server computer 4 by the user is permitted. Thereby, the user can access the server computer 4.

  In step S11, when the transmission duration time elapses and the transmission of the ID signal from the ID signal transmission device 1 stops, the device ID 24 and the user ID 28A, 28B or 28C from the ID signal reception device 2 to the management device 3 Will not be sent. In response to this, the management device 3 prohibits the user from accessing the server computer 4. As a result, the user cannot access the server computer 4.

  As described above, the ID signal transmission device 1 according to the embodiment of the present invention has the fingerprint detection unit 13. Accordingly, the user can carry the ID signal transmission device 1 and have the fingerprint detection unit 13 provided in the carried ID signal transmission device 1 detect his / her fingerprint information. In the conventional authentication system described above, since the fingerprint information detecting means is provided on the ID signal receiving device side, the user has to approach the receiving device in order to detect his / her fingerprint information. According to the ID signal transmission device 1 according to the embodiment, the user does not have to approach the ID signal receiving device 2 side in order to detect his / her fingerprint information. Therefore, according to the ID signal transmission device 1, the fingerprint detection unit 13 and the fingerprint authentication module 14 do not approach the ID signal reception device 2 side while improving the security level that does not allow unauthorized use due to loss or theft. However, the convenience of the active RFID that ID authentication can be performed can be sufficiently exhibited.

  The ID signal transmission device 1 stores a fingerprint information template in the storage unit 25 of the fingerprint authentication module 14 built in the ID signal transmission device 1. The fingerprint information detected from the user's finger and the template stored in the storage unit 25 are also verified by the fingerprint verification unit 26 of the fingerprint authentication module 14 built in the ID signal transmission device 1. In this way, the ID signal transmission device 1 performs fingerprint authentication itself. In the above-described conventional authentication system, since the receiving device side system performs fingerprint authentication, the load on the receiving device side system becomes heavy. However, according to the ID signal transmission device 1 according to the embodiment of the present invention, the receiving device side system is Since it is not necessary to perform fingerprint authentication, the load on the receiving apparatus side system can be reduced.

  For example, when there are a large number of users to be registered, in the conventional authentication system, it is necessary to register the fingerprint information template of all the users in the receiving apparatus side system. As a result, every time there is a request for fingerprint authentication, a template necessary for fingerprint authentication must be quickly identified from among a large number of templates, and a heavy load is imposed on the system to realize this. On the other hand, according to the ID signal transmission device 1 according to the embodiment of the present invention, the ID signal transmission device 1 is prepared for each user to be registered or for each group of three or four users to be registered. Then, the fingerprint information template of the user can be distributed and registered in the plurality of ID signal transmission devices 1. Therefore, according to the ID signal transmission device 1, the load on the management device 3 can be reduced. Even when there are a large number of users to be registered, the fingerprint information templates of users are registered in a distributed manner in a plurality of ID signal transmission devices 1, so that the burden of fingerprint authentication in each ID signal transmission device 1 is It won't be heavy.

  The ID signal transmission device 1 stores a fingerprint information template in the storage unit 25 of the fingerprint authentication module 14 built in the ID signal transmission device 1. The fingerprint information detected from the user's finger and the template stored in the storage unit 25 are also verified by the fingerprint verification unit 26 of the fingerprint authentication module 14 built in the ID signal transmission device 1. As a result, the template of the user's fingerprint information, which is personal information important to the user, is placed in the ID signal transmission device 1, and this template is also used when collating the fingerprint information. Never go out of one. Therefore, when the user carries the ID signal transmission device 1, the user's own fingerprint information can be managed easily.

  The ID signal transmission device 1 transmits the ID signal by the active RFID module 12 when the fingerprint information detected by the fingerprint detection unit 13 matches the template stored in the storage unit 25 of the fingerprint authentication module 14. And starting the transmission of the ID signal, the transmission of the ID signal is stopped when the transmission continuation time set by the administrator has elapsed. That is, the period during which the active RFID module 12 transmits the ID signal is from when the user's fingerprint is authenticated and the transmission continuation time elapses from that point. During other periods, the transmission of the ID signal by the active RFID module 12 is stopped. Thereby, power consumption by the active RFID module 12 can be reduced as compared with the case where the transmission of the ID signal is always continued. Therefore, the life of the battery 11 can be extended. Therefore, the replacement frequency of the battery 11 can be lowered, and the convenience of the ID signal transmission device can be enhanced for the user.

  Also, the ID signal transmission device 1 starts transmitting an ID signal when the user's fingerprint is authenticated. Therefore, by one operation of user's fingerprint authentication, security improvement that does not allow unauthorized use (use by a person other than legitimate user) due to loss or theft, etc., and power consumption by controlling the start of ID signal transmission Two effects of reduction can be obtained at the same time.

  The ID signal transmission device 1 transmits the ID signal by the active RFID module 12 when the fingerprint information detected by the fingerprint detection unit 13 matches the template stored in the storage unit 25 of the fingerprint authentication module 14. And starting the transmission of the ID signal, the transmission of the ID signal is stopped when the transmission continuation time set by the administrator has elapsed. Thereby, the load concerning the reception processing of the device ID 24 in the ID signal receiving device 2 or the management device 3 can be reduced.

  For example, in the conventional authentication system, since the device ID is constantly transmitted from the wireless transmitter, in the receiving device side system, processing for appropriately setting the reception timing interval of the device ID, and transmission is performed outside the reception timing. It was necessary to perform a reception process such as a process of ignoring the device ID. On the other hand, according to the ID signal transmission device 1 according to the embodiment of the present invention, such reception processing is not required in the ID signal receiving device 2 or the management device 3. The load on the management apparatus 3 can be reduced.

  Further, in the ID signal transmission device 1, the transmission duration information 31 stored in the storage unit 30 of the transmission control module 15 of the ID signal transmission device 1 can be changed, thereby changing the transmission duration of the ID signal. can do. Therefore, the administrator of the ID signal transmission device 1 can arbitrarily set / change the ID signal transmission duration in accordance with the management target or management mode of the server computer access management system 100. Therefore, according to the ID signal transmission device 1, it is possible to meet various requests (management targets, modes, etc.) of the receiving device side system.

  For example, when a user accesses the server computer 4 to perform simple paperwork, the time for accessing the server computer 4 may be about 10 minutes. In this case, the call duration is set to 10 minutes. On the other hand, when a user accesses the server computer 4 to perform complicated paperwork, it may take about 1 hour to access the server computer 4. In this case, the call duration is set to 1 hour. On the other hand, in order to improve security, for example, when authenticating a user or authenticating the device ID 24 every 30 minutes, the call duration is set to 30 minutes.

  Further, the ID signal transmission device 1 generates a composite ID by adding a user ID to the device ID, and transmits an ID signal modulated by the composite ID. Thereby, the ID signal transmission device 1 can make the management device 3 recognize the ID signal transmission device 1 that has transmitted the ID signal and the user of the ID signal transmission device 1 based on the ID signal. Therefore, it is possible to finely manage the server computer 4 by using information indicating which ID signal transmission device 1 is used and information indicating who uses the ID signal transmission device 1.

  The ID signal transmission device 1 includes a battery 11 and an active RFID module 12 that transmits an ID signal using power supplied from the battery 11. As a result, compared to a passive RFID module that does not have a power source and obtains power by an electromagnetic induction method, a large amount of power can be obtained, and the ID signal transmission distance can be increased. Therefore, the user who carries the ID signal transmission device 1 can transmit the ID signal from a place away from the ID signal reception device 2. That is, the user does not have to approach the ID signal receiving device 2 in order to transmit the ID signal. Therefore, the convenience of the ID signal transmission device 1 can be enhanced for the user.

  In the above-described embodiment, the ID signal transmission device of the present invention is applied to the server computer access management system 100 as an example, but the present invention is not limited to this. For example, the ID signal transmission device of the present invention can be applied to an entry / exit management system using an electric lock. In this case, the unlocking / locking of the electric lock is controlled by the ID signal transmitted from the ID signal transmitting device. In this case, since the transmission duration of the ID signal may be, for example, 2 or 3 seconds, the transmission duration information indicating the transmission duration of 2 or 3 seconds is stored in the storage unit of the transmission control module of the ID signal transmission device. Remember me.

  Further, in the above-described embodiment, the case where the fingerprint of the user is authenticated by the ID signal transmission device 1 is taken as an example, but the present invention is not limited to this. For example, other biological information such as an iris, a vein, and a face may be authenticated.

  In the embodiment described above, when the plurality of templates 27A, 27B, and 27C and the plurality of user IDs 28A, 28B, and 28C are stored in the ID signal transmission device 1 and the user's fingerprint information is detected, the user is detected. An example is given in which a user ID associated with a template that matches the fingerprint information is added to the device ID to generate a composite ID, and an ID signal modulated by this composite ID is transmitted. However, the present invention is not limited to this. On the premise that the number of users of the ID signal transmission device 1 is limited to one, storage of the user ID, addition of the device ID of the user ID, and the like may be abolished.

  Further, in the above-described embodiment, the case where the active RFID module 12 starts / stops the transmission of the ID signal is controlled by switching the power supply from the battery 11 to the active RFID module 12 as an example. However, the present invention is not limited to this, and the start and stop of transmission of the ID signal by the active RFID module 12 may be controlled by other methods.

  In the above-described embodiment, the active RFID module 12, the fingerprint authentication module 14, and the transmission control module 15 are provided as an example in the ID signal transmission device 1. However, these three modules are integrated into one chip. May be.
