Description

  The present invention relates to a security system, and more particularly, to a security system having a function of performing biometric authentication using a user's biometric information and unlocking a key when a normal authentication is performed.

  With the recent increase in crimes such as vacant nests, machine security systems are being introduced not only in retail stores and buildings, but also in individual houses and apartment houses. Conventionally, a mechanical security system that has been introduced employs a system that detects a problem by using, as a trigger, an abnormal signal of a sensor such as opening / closing of a door or window of a security device installed in a house or a fire detection.

  FIG. 14 is a diagram illustrating a functional configuration of a security device that detects a problem using a sensor abnormal signal as a trigger. As shown in FIG. 14, the security device 600 includes an operation unit 610, an external input port 620, and a notification unit 630. The operation unit 610 includes a screen display unit 611 and a key input unit 612.

  The screen display unit 611 displays instructions from the security device 600, the status of the security device 600, and the like when performing machine security. For example, it is displayed whether or not security is currently enabled. The key input unit 612 is, for example, a setting key for setting the security device 600. By pressing this setting key, the security device 600 is set or released.

  To the external input port 620, a door opening detection sensor 710, a window opening detection sensor 720, a vibration detection sensor 730, and a fire detection sensor 740 are connected. For example, the door opening detection sensor 710 is composed of two sets each having a magnet on one side and a sensor for detecting magnetism on the other side. When the door is closed on the door of the entrance and the frame, the magnetic sensor Install it close enough to detect the magnetic force of the magnet. Then, when the sensor for detecting magnetism cannot detect the magnetism of the magnet, it detects that the door is opened.

  When the door open detection sensor 710 detects that the door is opened, it outputs an abnormality detection signal to the notification unit 630 via the external input port 620. Then, when receiving the abnormality detection signal, the reporting unit 630 reports to the outside that an abnormality has been detected. Similarly, window detection sensor 720, vibration detection sensor 730, and fire detection sensor 740 output an abnormality detection signal to notification unit 630 via external input port 620 when an abnormality is detected. Then, when receiving the abnormality detection signal, the reporting unit 630 reports to the outside that an abnormality has been detected.

  FIG. 15 is a diagram illustrating a system configuration example of a machine security system that detects a problem using a sensor abnormal signal as a trigger. As shown in FIG. 15, the security device 600 is connected to the security center 800 via a network 631. For example, when the sensor 700 is installed in a general house and the sensor 700 detects an abnormality, the security device 600 notifies the security center 800 that the abnormality has been detected via the network 631. For example, the security center 800 is a management center of a security company. When an abnormality detection report is received, the security center 800 specifies a house where the security device 600 is installed, and issues a dispatch command to the security guard. And a guard goes to the house where the security apparatus 600 is installed, and confirms abnormality.

  On the other hand, recent door keys read and store the biometric information (palm vein pattern, finger vein pattern, fingerprint, etc.) of the individual operator, and read and store the biometric information read during the opening / closing operation. There has been proposed an electronic lock that performs personal authentication by comparing with biometric information, and opens the key.

  FIG. 16 is a diagram illustrating a functional configuration of a door key unit that performs personal authentication using biometric information. As shown in FIG. 16, the door key unit 900 includes an operation unit 910, a biometric information storage unit 920, a biometric information comparison unit 930, and a key release driver unit 940. The operation unit 910 includes a screen display unit 911, a key input unit 912, and a biological information reading unit 913.

  The screen display unit 911 displays an instruction from the door key unit 900, a state of the door key unit 900, a result of biometric authentication, and the like when performing biometric authentication. The key input unit 912 is, for example, a setting key for setting the door key unit 900, a reading start key for starting reading of biological information, and the like. The biometric information reading unit 913 reads biometric information of a user who intends to unlock. The biometric information storage unit 920 stores biometric information of a user who is permitted to authenticate in advance. Then, the biometric information comparison unit 930 compares the biometric information read by the biometric information reading unit 913 with the biometric information stored in advance in the biometric information storage unit 920 and determines whether or not they match. If they match, the key release unit 941 unlocks the key via the key release driver unit 940. If they do not match, the screen display unit 911 displays an unlocking impossible display.

In addition, an unlocking sensor that detects unlocking of the door key, a fingerprint sensor that reads the fingerprint of the hand touching the door knob, a fingerprint comparison unit that compares the fingerprint stored in advance with the fingerprint read by the fingerprint sensor, A communication unit that receives a control signal from the unlocking sensor and notifies the security company computer that the lock is illegally released via the telephone line when the fingerprint comparison unit determines that the fingerprints do not match. Has been proposed (see Patent Document 1).
Japanese Patent Laid-Open No. 2002-183843 (paragraph numbers [0023] to [0028], FIG. 1)

  However, in the conventional security system, when the door or the door is opened, the sensor detects an abnormality, and the security operation is started by reporting the fact to the security company. That is, even if the door is opened and the sensor detects an abnormality, there is a problem that the criminal is left unattended until the guard arrives at the house where the security device is installed.

  This invention is made | formed in view of such a point, and it aims at providing the security system which can make a guard's initial action early.

  In the present invention, in order to solve the above-mentioned problem, in the security system having a function of performing biometric authentication using the biometric information of the user as shown in FIG. The biometric information reading means 1a to be read, the biometric information storage means 1b for storing the normal biometric information that is the biometric information of the person to be normally authenticated, the user biometric information and the normal biometric information are compared, and a match / mismatch is determined. When it is determined to be coincident, a coincidence determination signal is output, and when it is determined to be disagreement, biometric information comparing means 1c that outputs user biometric information as disagreement biometric information, and a locking device that unlocks the key when receiving the coincidence determination signal 1d, the mismatched biological information storage means 2a for receiving and storing the mismatched biological information via the network 3, and the suspicious person biological information which is the biological information of the suspicious person Suspicious person biometric information storage means 2b for storing information in advance, unmatched biometric information and suspicious person biometric information are compared, unmatched biometric information comparison means 2c for determining coincidence mismatch, and unmatched biometric information and suspicious person biometric information match. Then, the server apparatus which has the suspicious person judgment means 2d which judges that the person specified from unmatched biometric information is a suspicious person, and the reporting means 2e which reports outside when the suspicious person judgment means 2d judges that it is a suspicious person. 2 is provided.

  Thereby, the biometric information reading means 1a reads the user biometric information which is the biometric information of the user. The biometric information storage unit 1b stores in advance normal biometric information that is biometric information of a person who is normally authenticated. The biometric information comparison unit 1c compares the user biometric information with the normal biometric information, determines a match / mismatch, outputs a match determination signal when the match is determined, and determines the user bioinformation as the mismatch biometric information when the match is determined. Output. When receiving the coincidence determination signal, the locking device 1d unlocks the key. The mismatch biometric information storage unit 2a receives and stores mismatch biometric information via the network 3. The suspicious person biometric information storage unit 2b stores in advance suspicious person biometric information that is biometric information of the suspicious person. The mismatch biometric information comparison unit 2c compares the mismatch biometric information with the suspicious person biometric information and determines a match / mismatch. The suspicious person determining means 2d determines that the person specified from the unmatched biometric information is a suspicious person when the unmatched biometric information matches the suspicious person biometric information. If the suspicious person judging means 2d determines that the suspicious person judging means 2d is a suspicious person, the notifying means 2e informs the outside.

  According to the security system of the present invention, when biometric authentication fails, it is possible to automatically determine whether the person is a suspicious person using the user's biometric information read at the time of biometric authentication. It is possible to report to a security company before a person enters a building such as a house. Therefore, since the initial operation of the guarding operation can be accelerated, it is possible to reduce the time for performing criminal acts by criminals. In addition, if a security guard arrives before entering the building, crime can be prevented.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[First Embodiment]
FIG. 1 is a conceptual diagram of the invention applied to this embodiment. The security device 1 shown in FIG. 1 includes a biological information reading unit 1a, a biological information storage unit 1b, a biological information comparison unit 1c, and a locking device 1d. The server device 2 includes a mismatch biometric information storage unit 2a, a suspicious person biometric information storage unit 2b, a mismatch biometric information comparison unit 2c, a suspicious person determination unit 2d, and a notification unit 2e. The security device 1 and the server device 2 are connected via a network 3.

  The biometric information reading unit 1a reads user biometric information which is biometric information of a biometric authentication user. The biometric information storage unit 1b stores in advance normal biometric information that is biometric information of a person who is normally authenticated in biometric authentication. The biometric information comparison unit 1c compares the user biometric information read by the biometric information reading unit 1a with the normal biometric information stored in advance by the biometric information storage unit 1b to determine coincidence. If it is determined that they match, a key unlock signal is output to the locking device 1d. If it is determined that there is a mismatch, the user biometric information is transmitted to the server device 2. When receiving the key unlock signal, the locking device 1d unlocks the key.

  The mismatch biometric information storage unit 2a stores the biometric information sent from the security device 1 as mismatch biometric information. The suspicious person biometric information storage unit 2b stores in advance biometric information of a person who has committed a crime before or a person who is likely to commit a crime. The mismatch biometric information comparison unit 2c reads the mismatch biometric information from the mismatch biometric information storage unit 2a. The suspicious person biometric information is read from the suspicious person biometric information storage means 2b. Then, the mismatch biometric information and the suspicious person biometric information are compared to determine a match / mismatch and output to the suspicious person determination means 2d.

  The suspicious person judgment means 2d receives the judgment result from the mismatch biometric information comparison means 2c. If it is determined that they match, the person specified by the mismatch biometric information is determined to be a suspicious person. When it is determined that there is a mismatch, it is determined whether or not the biometric information identical to the mismatched biometric information is stored in the mismatched biometric information storage unit 2a for a certain number of times. If it is stored more than a certain number of times, it is determined that the person specified by the mismatched biometric information is a suspicious person. The reporting unit 2e reports to the outside that the suspicious person determining unit 2d has determined that the person specified by the mismatched biometric information is a suspicious person.

  According to such a security system, when biometric authentication fails, it is possible to automatically determine whether or not the person is a suspicious person by using the user's biometric information read at the time of biometric authentication. It is possible to report to a security company before a person enters a building such as a house. Therefore, since the initial operation of the guarding operation can be accelerated, it is possible to reduce the time for performing criminal acts by criminals. In addition, if a security guard arrives before entering the building, crime can be prevented.

  FIG. 2 is a diagram illustrating a system configuration example according to the present embodiment. As shown in FIG. 2, the security device 100 is connected to the security center 200 via the network 10. In addition, the operation unit 110 and the sensor 300 are connected to the security device 100. The security device 100a is connected to the security center 200 via the network 10a. In addition, the security device 100a is configured such that an operation unit and a sensor (not shown) are connected in the same manner as the security device 100. The server device 210 is installed in the security center 200 and is connected to the security devices 100 and 100a via the networks 10 and 10a.

  The security devices 100 and 100a are security machines installed in a house or the like, and have a function for performing biometric authentication, a function for detecting an abnormality with a sensor, and a function for opening and closing a key. The biometric authentication is performed by receiving the biometric information of the user read by the operation unit 110 and comparing it with the biometric information of the person who permits the authentication stored in advance. If they match, the key is unlocked as having been successfully authenticated. If they do not match, the biometric information of the user is transmitted to the server device 210 because the authentication has failed. Further, when the sensor 300 detects an abnormality, it notifies the security center 200 and requests security dispatch.

  When the security center 200 is a security company or the like and receives a signal that has detected an abnormality, the security center 200 identifies a house that has output the signal from the received signal, and instructs the security guard to perform security for the house. The server device 210 stores biometric information of the suspicious person in advance. And when the biometric information which failed in authentication is received from the security devices 100 and 100a, the received biometric information is stored. Moreover, it compares with the biometric information of the suspicious person stored beforehand. If it is determined that they match, the user who has failed authentication is determined to be a suspicious person. If it is determined that they do not match, it is determined whether or not the same biometric information as the user's biometric information stored in the server device 210 has been stored for a certain number of times. If it has been stored more than a certain number of times, the user who has failed authentication is determined to be a suspicious person. When the server device 210 determines that the user who has failed the authentication is a suspicious person, the server device 210 notifies the security center 200 to that effect and requests the security operation.

Next, processing functions of the security device 100 will be described.
FIG. 3 is a diagram illustrating processing functions of the security device. As shown in FIG. 3, the security device 100 includes an operation unit 110, a biological information storage unit 120, a biological information comparison unit 130, a key release driver unit 140, a communication unit 150, and an external input port 160. The operation unit 110 includes a screen display unit 111, a key input unit 112, and a biological information reading unit 113.

  The biometric information reading unit 113 reads a user vein pattern, which is a vein pattern of the palm of a biometric authentication user who wants to unlock. The biometric information storage unit 120 stores in advance a normal vein pattern that is a vein pattern of a user who permits authentication. Then, the biometric information comparison unit 130 compares the user vein pattern read by the biometric information reading unit 113 with the normal vein pattern stored in advance in the biometric information storage unit 120 to determine whether or not they match. To do. If it is determined that the keys match, the key release unit 400 unlocks the key via the key release driver unit 140. If it is determined that there is a mismatch, the user vein pattern is transmitted to the server device 210 installed in the security center 200 via the communication unit 150.

  In addition, a door opening detection sensor 310, a window opening detection sensor 320, a vibration detection sensor 330, and a fire detection sensor 340 are connected to the external input port 160. For example, the door opening detection sensor 310 is composed of two sets each having a magnet on one side and a sensor for sensing magnetism on the other side. When the door is closed on the door and the frame of the door, the magnetic sensor Install it close enough to detect the magnetic force of the magnet. Then, when the sensor for detecting magnetism cannot detect the magnetism of the magnet, it detects that the door is opened.

  When the door open detection sensor 310 detects that the door is open, it outputs an abnormality detection signal to the communication unit 150 via the external input port 160. When receiving the abnormality detection signal, the communication unit 150 notifies the security center 200 that an abnormality has been detected. Similarly, the window detection sensor 320, the vibration detection sensor 330, and the fire detection sensor 340 output an abnormality detection signal to the communication unit 150 via the external input port 160 when an abnormality is detected. When receiving the abnormality detection signal, the communication unit 150 notifies the security center 200 that an abnormality has been detected.

Next, processing functions of the server device 210 installed in the security center 200 will be described.
FIG. 4 is a diagram illustrating processing functions of the server device. As illustrated in FIG. 4, the server device 210 includes a communication unit 211, a mismatched biometric information storage unit 212, a suspicious person biometric information storage unit 213, a mismatched biometric information comparison unit 214, a suspicious person determination unit 215, and a notification unit 216. ing.

  When the communication unit 211 receives a mismatched vein pattern that is a vein pattern of a user who has failed authentication from the security device 100, the communication unit 211 stores the mismatched biological information storage unit 212. The suspicious person biometric information storage unit 213 stores a suspicious person's vein pattern which is a suspicious person's vein pattern in advance. The mismatch biometric information comparison unit 214 reads a mismatch vein pattern stored in the mismatch biometric information storage unit 212. Further, the suspicious person vein pattern stored in advance in the suspicious person biological information storage unit 213 is read out. Then, the mismatched vein pattern and the suspicious person vein pattern are compared to determine a match / mismatch, and the determination result is output to the suspicious person determination unit 215.

  When the suspicious person determination unit 215 receives the determination result that the non-matching biometric information comparison unit 214 determines to match, the suspicious person determination unit 215 determines that the person specified from the non-matching vein pattern is a suspicious person. That is, the user who has failed authentication is determined as a suspicious person. When a determination result determined to be inconsistent is received, it is determined whether or not a mismatched vein pattern is stored in the mismatched biometric information storage unit 212 more than a predetermined number of times. And when it has memorize | stored more than fixed number of times, the user who failed in authentication is judged as a suspicious person. When the suspicious person determination unit 215 determines that the user who has failed in authentication is a suspicious person, the suspicious person determination unit 215 notifies the security center 200 to that effect via the notification unit 216.

  In the case of a security company, information about a person who has previously committed a crime or attempted crime may exist in the form of a blacklist. Therefore, the vein pattern of the suspicious person stored in the suspicious person biometric information storage unit 213 is created using a black list or the like possessed by the security company. Then, it becomes possible to report immediately without waiting for the same vein pattern to be stored more than a certain number of times. For example, when the predetermined number of times is five, since the vein pattern is only stored in the mismatched biometric information storage unit 212 from the first to the fourth time and is not reported, a person who is known as a suspicious person is described in advance. If there is a blacklist, it is possible to store the vein pattern described in the blacklist in the suspicious person's biometric information storage unit 213 and report it immediately, so that the initial action of the guard operation can be made faster, and the crime It helps to deter.

Next, a specific example of data stored in the mismatch biometric information storage unit 212 of the server device 210 will be described.
FIG. 5 is a diagram illustrating an example of the data structure of the mismatch biometric information table. As shown in FIG. 5, the mismatch biometric information table 500 stored in the mismatch biometric information storage unit 212 includes columns for number, acquisition date and biometric information. The information arranged in the horizontal direction in each column is associated with each other, and constitutes a record related to the vein pattern that the biometric information comparison unit 130 determines to be inconsistent.

  In the number column, a serial number assigned every time a vein pattern determined to be inconsistent is stored is set. The date and time when the vein pattern determined to be inconsistent is acquired by the security device 100 via the biometric information reading unit 113 is set in the acquisition date and time column. In the biometric information column, the vein pattern read from the biometric information reading unit 113 is set as an image file in JPEG (Joint Photographic Experts Group) format.

The following processing is performed by the security system having the above functions and data.
FIG. 6 is a flowchart showing a procedure of vein pattern authentication processing by the security system according to the present embodiment. In the following, the process illustrated in FIG. 6 will be described in order of step number.

[Step S11] The biometric information reading unit 113 reads the vein pattern of the palm of the user who performs biometric authentication.
[Step S12] The biometric information comparison unit 130 includes a user vein pattern that is a user's vein pattern read by the biometric information reading unit 113 and a normal vein pattern that is a vein pattern stored in advance in the biometric information storage unit 120. And compare. In the biometric information storage unit 120, a vein pattern of a person who may unlock the key of the entrance door is stored in advance as a normal vein pattern.

  [Step S13] The biometric information comparison unit 130 compares the user vein pattern with the normal vein pattern to determine a match / mismatch. If the compared vein patterns match, the process proceeds to step S14. If the compared vein patterns do not match, the process proceeds to step S15.

[Step S14] The key release driver unit 140 unlocks the key by the key release unit 400 and ends the process.
[Step S15] The biometric information comparison unit 130 transmits the user vein pattern used for the comparison to the server device 210 installed in the security center 200 via the communication unit 150. When the server device 210 receives the user vein pattern, the server device 210 stores it in the mismatch biometric information table 500 in the mismatch biometric information storage unit 212.

  [Step S <b> 16] The mismatch biometric information comparison unit 214 reads the user vein pattern received from the server device 210 and the suspicious person vein pattern stored in advance in the suspicious person biometric information storage unit 213. For example, in the case of a security company, information on a person who has previously committed a crime or attempted crime may exist in the form of a blacklist. The suspicious person vein pattern stored in advance in the suspicious person biometric information storage unit 213 is created from a black list or the like held by the security company.

  [Step S17] The mismatch biometric information comparison unit 214 compares the user vein pattern with the suspicious person vein pattern to determine a match / mismatch, and outputs the determination result to the suspicious person determination unit 215. If it is determined that the mismatch biometric information comparison unit 214 matches, the process proceeds to step S18, and if it is determined that there is a mismatch, the process proceeds to step S20.

  [Step S18] The suspicious person determination unit 215 determines that the user is a suspicious person. Then, the fact is reported to the security center 200 via the reporting unit 216. The security center 200 is, for example, a management center of a security company, and when a report is received from the security device 100, a security officer is dispatched to secure a suspicious person or confirm the situation.

[Step S19] The biological information comparison unit 130 displays on the screen display unit 111 in the operation unit 110 that the entrance door cannot be unlocked, and ends the process.
[Step S20] The suspicious person determination unit 215 determines whether or not the user's vein pattern stored in the mismatch biometric information storage unit 212 has been stored more than a certain number of times. If the predetermined number of times is stored, the process proceeds to step S18. If the predetermined number of times is not stored, the process proceeds to step S19. For example, when the predetermined number of times is set to five, the suspicious person determination unit 215 determines that the person having the stored vein pattern is a suspicious person when the same vein pattern is stored five times, and the notification unit Via 216, the security center 200 is notified that the user has been determined to be a suspicious person.

  Although the biometric information has been described as a palm vein pattern, the biometric information is not limited to the palm vein pattern, and a finger vein pattern, iris, fingerprint, or the like may be used. When using a fingerprint, the following call button may be used.

  FIG. 7 is an external view of the operation unit of the present embodiment. As illustrated in FIG. 7, the operation unit 110 includes a screen display unit 111, a key input unit 112, and a biological information reading unit 113. The screen display unit 111 displays an instruction from the security device 100 when performing biometric authentication. The user performs an operation according to an instruction displayed on the screen display unit 111. The key input unit 112 is, for example, a numeric keypad for inputting a password or a setting key for setting the security device 100. By pressing this setting key, operations such as security start and security release of the security device 100 are performed. Moreover, you may enable it to change the security standard of the security apparatus 100, etc. The biometric information reading unit 113 reads a fingerprint of a user who intends to unlock.

  FIG. 8 is a cross-sectional view of the biological information reading unit of the present embodiment. As shown in FIG. 8, the biological information reading unit 113 includes a fingerprint reading table 114, a fingerprint reader 115, and a call button contact unit 116. The biometric information reading unit 113 is configured to also serve as a call button. That is, when the user presses the fingerprint reading table 114, the calling button contact portion 116a provided on the fingerprint reader 115 and the calling button contact portion 116b provided on the operation unit 110 side come into contact with each other to perform a calling process. At the same time, the fingerprint reader 115 reads the fingerprint of the finger in contact with the fingerprint reading table 114.

FIG. 9 is a flowchart illustrating a procedure of fingerprint reading processing by the biometric information reading unit. In the following, the process illustrated in FIG. 9 will be described in order of step number.
[Step S31] The biological information reading unit 113 determines whether the call button has been pressed. If so, the process proceeds to step S32. If not, the process proceeds to step S31. That is, the process proceeds to step S32 with the act of pressing the call button as a trigger.

  [Step S32] The biological information reading unit 113 reads the fingerprint of the finger on the fingerprint reading table 114. The fingerprint reading table 114 is provided with a fingerprint reader 115 for reading a fingerprint. At the same time as the calling process is performed by contacting the call button contact portion 116, the fingerprint reader is activated and the finger on the fingerprint reading table 114 is moved. Read the fingerprint. By adopting such a configuration, since the fingerprint reader 115 reads the fingerprint of the finger on the fingerprint reading table 114 simultaneously with the action of pressing the call button, the fingerprint can be reliably collected.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. The security system according to the present embodiment is assumed to be applied to a housing complex such as an apartment. In the following description, components that are substantially the same as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted as appropriate.

  FIG. 10 is a diagram showing a system configuration example according to the present embodiment. As shown in FIG. 10, door key units 2110a to 2110g are provided at the entrance and the doors of the rooms. Further, the door key units 2110a to 2110g are connected to the communication unit 2100, respectively. The communication unit 2100 is connected to the security center 2200 via the network 10.

  The door key unit 2110a has a function for reading the vein pattern and a function for opening and closing the key. The communication unit 2100 receives the vein pattern read by the door key unit 2110a, and performs biometric authentication by comparing it with a normal vein pattern that is a vein pattern of a person who is permitted to authenticate in advance. If the vein patterns match, the door key unit 2110a is notified of successful authentication. Upon receiving the notification, the door key unit 2110a unlocks the key. If the biometric information does not match, the user vein pattern which is the vein pattern of the user who has failed in authentication is stored. Further, the user vein pattern is compared with the suspicious person vein pattern stored in advance in the communication unit 2100 to determine coincidence / mismatch. And when it matches with a suspicious person's vein pattern, a user is judged to be a suspicious person. If the vein pattern does not match the suspicious person's vein pattern, it is determined whether or not the communication unit 2100 has stored the vein pattern more than a certain number of times. If it is stored more than a certain number of times, the user is determined to be a suspicious person. When the communication unit 2100 determines that the user is a suspicious person, the communication unit 2100 reports to the security center 2200 and requests security dispatch.

Next, processing functions of the door key unit 2110a will be described.
FIG. 11 is a diagram illustrating processing functions of the door key unit. As shown in FIG. 11, the door key unit 2110 a includes an operation unit 110, a key release driver unit 140, and a communication unit 150. The operation unit 110 includes a screen display unit 111, a key input unit 112, and a biological information reading unit 113.

  The biometric information reading unit 113 reads a user vein pattern, which is a vein pattern of the palm of a biometric authentication user who wants to unlock. When the vein authentication using the user vein pattern read by the biometric information reading unit 113 is permitted, the key release driver unit 140 unlocks the key by the key release unit 400. The communication unit 150 transmits the vein pattern read by the biological information reading unit 113 to the communication unit 2100. Although only the door key unit 2110a has been described, it is assumed that the door key units 2110b to 2110b-g have the same configuration and have the same function.

Next, processing functions of the communication unit 2100 will be described.
FIG. 12 is a diagram illustrating processing functions of the communication unit. As illustrated in FIG. 12, the communication unit 2100 includes a biological information storage unit 120, a communication unit 211, a suspicious person biological information storage unit 213, a mismatched biological information comparison unit 214, a suspicious person determination unit 215, a notification unit 216, and a biological information comparison. Unit 2130 and a mismatched biometric information storage unit 2212.

  The biometric information storage unit 120 stores in advance the vein patterns of users who are permitted to authenticate. The biometric information comparison unit 2130 receives a user vein pattern that is a user's vein pattern read by the biometric information reading unit 113 via the communication unit 211. Further, a normal vein pattern which is a vein pattern of a person who may be unlocked and stored in advance in the biometric information storage unit 120 is read out. Then, the vein pattern of the user is compared with the normal vein pattern to determine whether or not they match. If they match, a signal to permit authentication is output to the door key unit 2110a via the communication unit 211. In the case of a mismatch, the user vein pattern that has failed in authentication is stored in the mismatch biometric information storage unit 2212 as a mismatched vein pattern. The suspicious person biometric information storage unit 213 stores a suspicious person's vein pattern which is a suspicious person's vein pattern in advance. The mismatch biometric information comparison unit 214 reads the mismatch vein pattern stored in the mismatch biometric information storage unit 2212. Further, the suspicious person vein pattern stored in advance in the suspicious person biological information storage unit 213 is read out. Then, the mismatched vein pattern and the suspicious person vein pattern are compared to determine a match / mismatch, and the determination result is output to the suspicious person determination unit 215.

  When the suspicious person determination unit 215 receives the determination result that the unmatched biometric information comparison unit 214 determines to be a match, the suspicious person determination unit 215 determines that the user who has failed the authentication is a suspicious person. When the determination result determined to be inconsistent is received, it is determined whether or not the mismatched vein pattern is stored in the mismatched biometric information storage unit 2212 more than a predetermined number of times. And when it has memorize | stored more than fixed number of times, the user who failed in authentication is judged as a suspicious person. When the suspicious person determination unit 215 determines that the user who has failed in authentication is a suspicious person, the suspicious person determination unit 215 notifies the security center 200 to that effect via the notification unit 216.

Next, a specific example of data stored in the mismatch biometric information storage unit 2212 of the communication unit 2100 will be described.
FIG. 13 is a diagram illustrating an example of the data structure of mismatched biometric information. As shown in FIG. 13, the mismatch biometric information table 2500 stored in the mismatch biometric information storage unit 2212 includes columns for number, acquisition date / time, biometric information, and acquisition location. The information arranged in the horizontal direction in each column is associated with each other, and constitutes a record related to the vein pattern that the biometric information comparison unit 2130 determines to be inconsistent.

  In the number column, a serial number assigned every time a vein pattern determined to be inconsistent is stored is set. The date and time when the vein pattern determined to be inconsistent is acquired by the communication unit 2100 is set in the acquisition date and time column. In the biometric information column, the vein pattern read by the biometric information reading unit 113 is set as an image file in JPEG format. Further, the place where the door key unit that reads the vein pattern is installed is set in the field of the acquisition place.

  For example, consider a case where a resident in room 302 to which the door key unit 2110g is attached enters the room. The resident in room 302 performs biometric authentication using the door key unit 2110a attached to the entrance, and unlocks the entrance. Next, biometric authentication is performed using the door key unit 2110g attached to the door of the room 302, and the door of the room 302 is unlocked to enter the room.

  Since the communication unit 2100 performs biometric authentication at this time, for example, a resident in Room 302 mistakenly performs biometric authentication using the door key unit 2110f of Room 301, which is the adjacent room, or the door key unit 2110e of Room 202, which is the lower floor. When the authentication error occurs, the vein pattern of the inhabitant in room 302 that does not match is stored in the communication unit 2100. That is, when it is determined that the vein pattern does not match in biometric authentication, the vein pattern of the person who does not match is stored in the communication unit 2100 regardless of which door key unit of the door key units 2110a to 2110g does not match. Will be.

  Therefore, when a suspicious person tries biometric authentication one after another in the entrance, Room 101, Room 102, Room 201, all vein patterns of the suspicious person who failed in biometric authentication are stored in the communication unit 2100. . Then, it is possible to identify a suspicious person earlier than when detecting an abnormality at one place and reporting it by detecting an abnormality in authentication at multiple places rather than reporting due to multiple failed biometric authentications at one house. It becomes possible, and the initial action of the security guard becomes faster.

  By causing the security system to perform the above processing, a criminal such as a thief invades the house after intruding into the house like the conventional security system, and the initial delay that occurs inevitably occurs when the security guard is activated. It becomes possible to reduce. In other words, rather than detecting the actual intruder's intrusion and making a request for dispatch, the suspicious person is judged and identified before the intrusion is made, and the dispatch request is made, so that the initial action of the guard dispatch is accelerated. It is possible to prevent crimes, prevent crimes, and detect criminals early.

  Note that the suspicious person determination unit 215 is provided in the security device 100 without installing the server device 210, and the security device 100 notifies the security center 200 to that effect when the user is determined to be a suspicious person. The same effect as the security system can be demonstrated.
