Description

  The present invention relates to a technique for monitoring a person to be monitored using a tag and biometric authentication technique.

  Conventionally, there are various systems for monitoring a monitored person who is a monitoring target. For example, in a wireless local area network (LAN) system, a plurality of base stations detect mutual clock deviations by wireless communication with each other, and each base station is monitored based on its own base station clock. Measure the reception time of the signal from the terminal carried by the server, the server uses the reception time measured at each base station, the mutual clock offset detected at each base station, and the position of each base station Thus, a technique for detecting the position of a monitored person carrying a terminal is disclosed (for example, see Patent Document 1).

Also disclosed is a technique for extracting a vein pattern included in a photographed transmitted light image and collating the extracted vein pattern with a vein pattern of a finger image registered in advance to perform personal authentication of the monitored person. (For example, refer to Patent Document 2).
JP 2004-101254 A JP 2002-83298 A

  However, in the technique disclosed in Patent Document 1, it is possible to monitor the location of the person who carries the terminal, but the person being monitored has performed “replacement” that causes the person other than himself to carry the terminal. In some cases, there is a problem that it becomes impossible to monitor who should be monitored. In addition, there is a problem that it becomes impossible to monitor the person to be monitored even when the person being monitored performs “leave” without carrying the terminal.

  Further, in the technique disclosed in Patent Document 2, if the verification is successful, it can be determined that the person who has taken the finger image should be monitored, but if the verification fails, the verification fails. Provide a clear answer as to whether the cause of this is that the person whose finger image was taken is not to be monitored or that the verification process of the authentication device did not function properly There is no problem.

  Therefore, an object of the present invention is to more reliably perform monitoring of a monitored person who is a monitoring target.

  In order to achieve the above object, the present invention provides a tag / biological information storage unit that stores information held by a tag attached to a monitored person who is a monitoring target and biometric information of the monitored person, A tag information reading unit that reads information from the tag, a biological information acquisition unit that acquires biological information corresponding to the tag information read by the tag information reading unit from the tag / biological information storage unit, and biological information from the monitored person A configuration comprising: a biometric information reading unit that reads; a biometric authentication unit that collates biometric information acquired by the biometric information acquisition unit and biometric information read by the biometric information reading unit; and an authentication result output unit that outputs a result of the collation did.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to monitor the monitoring subject who is a monitoring object more reliably.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a functional configuration example of a monitoring system according to the present embodiment.
As shown in FIG. 1, the monitored person 200 is a person to be monitored by the monitoring system 100, and a tag 210 is attached to the monitored person 200. The tag 210 stores tag information including information for identifying the tag. The tag 210 may be directly attached to the body of the monitored person 200 or may be attached to the clothes of the monitored person 200. Further, if the tag 210 can be easily removed by the monitored person 200, it can be easily replaced, left behind, etc., and therefore it is preferable that the tag 210 is not easily removed. Specifically, a configuration in which the monitored person 200 can be removed only by using a key owned by a person in a position to monitor, a configuration in which a living body is embedded, and the like can be considered.

  The monitoring system 100 includes a tag information reading device 110 and a biometric authentication device 120.

  The tag information reading device 110 is a device that reads tag information from a tag 210 attached to the monitored person 200, and includes a tag information reading unit 111, a tag information transmitting unit 112, an antenna 112a, and an antenna 111a. Composed. Here, the tag information reading unit 111 and the tag information transmitting unit 112 are realized, for example, by a CPU (Central Processing Unit) executing a program stored in a memory. As hardware, it is realized by an RF (Radio Frequency) circuit for transmitting and receiving radio waves, a network interface card for wireless communication, a CPU, a RAM (Random Access Memory), a ROM (Read Only Memory), and the like.

  The antenna 111a functions as an antenna that transmits radio waves for reading and receives response waves (tag information).

  When the tag information reading unit 111 reads tag information from the tag 210 via the antenna 111a, the tag information reading unit 111 has a function of outputting the read tag information to the tag information transmitting unit 112.

  When tag information is input from the tag information reading unit 111, the tag information transmission unit 112 has a function of transmitting the input tag information to the biometric authentication device 120 via the antenna 112a.

  The antenna 112a is an antenna for wireless communication and has a function of performing wireless communication with the biometric authentication device 120.

  The biometric authentication device 120 includes a tag information receiving unit 121, an antenna 121a, a biometric information acquisition unit 122, a tag / biometric information storage unit 123, a biometric information reading unit 124, a biometric authentication unit 125, and an authentication result output unit. 126. Here, the tag information receiving unit 121, the biometric information acquiring unit 122, and the biometric authentication unit 125 are realized by the CPU executing a program stored in a memory, for example. As hardware, it is realized by a network interface card for wireless communication, CPU, RAM, HDD (Hard Disk Drive), flash memory, and the like.

  The tag information receiving unit 121 has a function of receiving tag information transmitted from the tag information transmitting unit 112 via the antenna 112 a via the antenna 121 a and outputting the tag information to the biological information acquiring unit 122.

  The antenna 121 a is an antenna for wireless communication and has a function of performing wireless communication with the tag information reading device 110.

  When the tag information is input from the tag information receiving unit 121, the biometric information acquiring unit 122 receives the biometric information (registered biometric information) registered in the tag / biometric information storage unit 123 based on the input tag information. It has a function of acquiring and outputting to the biometric authentication unit 125.

  The tag / biological information storage unit 123 has a function of storing tag information and biological information in association with each other as tag / biological information. For example, it is realized by a hard disk or a flash memory. This tag / biological information will be described later.

  The biometric information reading unit 124 has a function of reading biometric information from the monitored person 200 and outputting it to the biometric authentication unit 125. The biometric information includes finger vein information, iris image information, fingerprint information, voiceprint information, face image information, and the like. When using finger vein information, iris image information, fingerprint information, face image information, or the like as biometric information, the biometric information reading unit 124 is realized by a camera or the like, and when using voiceprint information or the like, biometric information reading is performed. The unit 124 is realized by a microphone or the like.

  The biometric authentication unit 125 collates the biometric information (read biometric information) input from the biometric information reading unit 124 with the biometric information (registered biometric information) input from the biometric information acquisition unit 122, and authenticates the authentication result. It has a function of outputting to the result output unit 126. As the authentication result, for example, there is a method of outputting a value of “0: authentication success” when the verification is successful, and “1: authentication failure” when the verification is unsuccessful.

  The authentication result output unit 126 has a function of outputting the authentication result input from the biometric authentication unit 125. For example, the authentication result output unit 126 is like a display screen. When “0: authentication success” is input from the biometric authentication unit 125, the authentication result output unit 126 is notified to the person who is to monitor the monitored person 200. If the message “authentication success” is displayed and “1: authentication failure” is input from the biometric authentication unit 125, the message “authentication” is transmitted to the person in a position to monitor the monitored person 200. "Failed" may be displayed. In addition, when “1: authentication failure” is input from the biometric authentication unit 125, the authentication result output unit 126 emits a warning sound informing the person who is to monitor the monitored person 200 to that effect. May be. When there is a person who should monitor the monitored person 200 near a device different from the biometric authentication device 120, the authentication result output unit 126 authenticates to a device different from the biometric authentication device 120. The result may be output.

FIG. 2 is a diagram illustrating an installation example of each device of the monitoring system according to the present embodiment.
As shown in FIG. 2, the person 200 to be monitored is in the room. Although three monitored persons 200 are shown in FIG. 2, the number of monitored persons 200 is not particularly limited. A tag 210 is attached to each monitored person 200.

  The tag information reader 110 is installed near the entrance of a room, for example, and reads the tag information of the tag 210 when the monitored person 200 enters the room. The tag information read by the tag information reading device 110 is transmitted to the biometric authentication device 120 wirelessly. The biometric authentication device 120 is carried by, for example, a supervisor 300 who monitors the monitored person 200, and when biometric information is input from the monitored person 200, tag information transmitted from the tag information reading apparatus 110 by radio. The biometric information corresponding to is collated. The result of the collation is displayed on the display screen of the biometric authentication device 120, for example, and can be confirmed by the supervisor 300.

  FIG. 3 is a diagram illustrating a configuration example of tag / biological information in the present embodiment. The tag / biological information 1230 stored in the tag / biological information storage unit 123 (see FIG. 1) includes tag information 1231 and biometric information 1232.

  The tag information 1231 is information that can uniquely identify the tag 210. For example, a MAC address (Media Access Control address) or the like can be used.

  The biological information 1232 is information that can uniquely identify the body of the monitored person 200 (see FIG. 1). For example, as described above, the biological information 1232 includes finger vein information, iris image information, fingerprint information, voice print information, face image information, and the like.

  FIG. 4 is a flowchart showing the flow of processing of the monitoring system in the present embodiment. With reference to FIG. 4 (refer to FIGS. 1 and 3 as appropriate), processing executed by the monitoring system 100 will be described.

  First, in the tag information reading device 110, the tag information reading unit 111 reads tag information from the tag 210 (step S101). Next, the tag information transmission unit 112 transmits the tag information read by the tag information reading unit 111 to the biometric authentication device 120 (step S102).

  Subsequently, in the biometric authentication device 120, the tag information receiving unit 121 receives the tag information transmitted from the tag information reading unit 111 (step S103). Then, the biometric information acquisition unit 122 acquires registered biometric information based on the tag information received by the tag information reception unit 121 (step S104). Specifically, the biometric information acquisition unit 122 searches the tag / biological information 1230 for data that matches the tag information 1231 received by the tag information receiving unit 121 and the biometric information 1232 (registered biometric information) of the data. Information). The biometric information reading unit 124 reads biometric information (read biometric information) from the monitored person 200 (step S105). Next, the biometric authentication unit 125 collates biometric information (step S106). Specifically, the biometric authentication unit 125 collates the registered biometric information with the read biometric information. And the authentication result output part 126 outputs the result of the collation as an authentication result (step S107).

  Here, the biometric authentication unit 125 performs verification once for one person 200 to be monitored, but the number of verifications is not particularly limited. For example, when the verification process in the biometric authentication unit 125 fails, the verification process may be performed a plurality of times until it succeeds. In that case, the biological information used for collation is not limited to one type. For example, the reliability of the verification function in the biometric authentication device 120 can be increased by using finger vein information in the first verification and using face image information in the second verification after the verification fails. In addition, the second verification may be performed by a person in a position to monitor the monitored person 200 by comparing face images.

  By the processing described above, the monitoring system of the present embodiment can prevent the “replacement” and “removal” of the tag by the monitor, and can reliably monitor the person who should be monitored. Even if the verification fails, if the biological information of the monitored person 200 is not registered in the tag / biological information storage unit 123, the monitored object is confirmed by checking a message such as “2: no registered information”. It is possible to determine that the person 200 is not a person who should be monitored, and when the biological information of the monitored person 200 is registered in the tag / biological information storage unit 123, “1: authentication failure” It is possible to determine that the verification process of the authentication device did not function normally by checking a message such as “”. That is, it is possible to more reliably monitor the monitored person who is the monitoring target.

  Although the present embodiment has been described above, the present embodiment can be freely changed within a range in which technical inconvenience does not occur. Hereinafter, a modification will be described with reference to FIG. For example, the monitoring system 100 includes a position detection system, and the position detection system detects a position of the tag 210 and detects the position of the tag 210 and outputs the position to the position display unit. The monitored person 200 can be more reliably monitored. As a position detection method, the position detection system includes at least three wireless LAN base stations (fixed stations whose positions are known), and the tag 210 has a function of transmitting radio waves at predetermined time intervals. The principle of three-point surveying, that is, the distance between each base station whose position is known and the tag 210 is obtained from the arrival time of the received radio wave to each base station or the arrival time of the radio wave transmitted from each base station to the tag 210. There is a method for detecting the position of the tag 210 by calculating the position of the tag 210. As the position detection system, Hitachi AirLocation (registered trademark) or the like can be used.

  In the present embodiment, the biometric authentication device 120 authenticates biometric information. However, the biometric authentication device 120 includes a biometric information output unit, and is input from the biometric information reading unit 124 via the biometric information output unit. The biometric information (read biometric information) and the biometric information (registered biometric information) input from the biometric information acquisition unit 122 are output, and the person who is to monitor the monitored person 200 outputs the read biometric information. The verification may be performed based on the registered biometric information. In that case, the biometric authentication device 120 may not include the biometric authentication unit 125 and the authentication result output unit 126.

  Furthermore, in this embodiment, the biometric information acquisition unit 122 acquires biometric information registered in the tag / biological information storage unit 123 based on the input tag information. The value “2: no registration information” may be directly output to the authentication result output unit 126. In this case, when “2: no registration information” is input from the biometric information acquisition unit 122, the authentication result output unit 126 sends a message “Registration” to the person who is to monitor the monitored person 200 to that effect. “No information” may be displayed. In addition, when “2: no registration information” is input from the biometric information acquisition unit 122, the authentication result output unit 126 emits a warning sound to notify the person in a position to monitor the monitored person 200. You may do it.

  In the present embodiment, the tag / biological information storage unit 123 has a function of storing tag information and biological information in association with each other as tag / biological information. It is good also as having a function to store as monitored person / biological information in correspondence. In that case, the biometric authentication device 120 includes a conversion unit that converts the tag information received by the tag information receiving unit 121 into the identification information of the monitored person 200, and the conversion unit converts the identification information of the monitored person 200 into the biological information acquisition unit. The data may be output to 122. Further, tag information received from the tag information transmitting unit 112 by a device different from the biometric authentication device 120 may be converted into identification information of the monitored person 200 and output to the tag information receiving unit 121.

  Furthermore, in the present embodiment, the tag 210 is used as the tag attached to the monitored person 200, but other than the tag 210 may be used as long as the monitored person 200 can be uniquely identified. . For example, an IC (Integrated Circuit) card may be used as an item attached to the monitored person 200. In this case, a card reader may be used instead of the tag information reading device 110.

  As shown in FIG. 5, the monitoring system 100A may be configured to include a biometric information reading device 130 in addition to the biometric authentication device 120A. In this case, the biological information reader 130 includes a biological information reader 131, a biological information transmitter 132, and an antenna 132a. The biological information reader 131 reads biological information from the monitored person 200, and the biological information transmitter 132 is configured to transmit the biometric information to the biometric authentication device 120A via the antenna 132a. The biometric authentication device 120A receives the biometric information transmitted from the biometric information reading device 130 via the antenna 125a. Also, with such a configuration, the tag information reading device 110 and the biological information reading device 130 are installed in each room of a facility having a plurality of rooms, and tag information is received from the tag information reading device 110 in each room. In addition, the biometric information can be received from the biometric information reading device 130 in each room, and one biometric authentication device 120A in the management room can perform biometric authentication of the monitored person 200 in a plurality of rooms. Of course, the tag information reading device 110 and the biological information reading device 130 may be installed outside the room.

  Further, as shown in FIG. 6, the monitoring system 100B includes a biometric authentication device 120B having a structure in which the biometric authentication device 120 (see FIG. 1) and the tag information reading device 110 (see FIG. 1) are integrated. Any configuration may be used.
