[Figure 6] FIG. 11 is a configuration diagram showing a personal authentication system according to a second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] Embodiment 1 1 is a block diagram showing a personal authentication system according to embodiment 1. The personal authentication system according to embodiment 1 includes a center device 1, an electric lock control device 2, an electric lock 3, a personal authentication information input device 4, and a camera 5.
[0010] The center device 1 is placed in a management room of a building. Therefore, the center device 1 is operated by a manager in the management room. The center device 1 is configured by, for example, a personal computer.
[0011] The center device 1 has a storage device 101 and an information registration device 102. A table is stored in the storage device 101. In the table stored in the storage device 101, personal authentication information of an authenticated person permitted to enter and leave an entry / exit restricted area and information on a plurality of actions of the authenticated person permitted to enter and leave the entry / exit restricted area are registered in advance in correspondence with each other. The personal authentication information of the authenticated person and the information on the plurality of actions of the authenticated person are used when determining entry and exit from the entry / exit restricted area.
[0012] The personal authentication information of the person to be authenticated that is registered in advance in the table is referred to as registered personal authentication information, and the information of a plurality of actions of the person to be authenticated that is registered in advance in the table is referred to as registered multiple action information.
[0013] The information registration device 102 is an input device for storing the table in the storage device 101. The administrator operates the information registration device 102, whereby the table is stored in the storage device 101.
[0014] The electric lock control device 2 is electrically connected to the center device 1. Although one electric lock control device 2 is shown in Fig. 1, the personal authentication system may include multiple electric lock control devices 2. In this case, the electric lock control device 2 may be disposed, for example, on each floor of a building having multiple floors.
[0015] The electric lock 3 is electrically connected to the electric lock control device 2. Although one electric lock 3 is shown in FIG.
[0016] The personal authentication information input device 4 is electrically connected to the electric lock control device 2. Although one personal authentication information input device 4 is shown in FIG. 1, the personal authentication system may include a plurality of personal authentication information input devices 4.
[0017] The camera 5 is electrically connected to the electric lock control device 2. Although one camera 5 is shown in Fig. 1, the personal authentication system may include multiple cameras 5. The electric lock 3, the personal authentication information input device 4, and the camera 5 are installed in correspondence with each other.
[0018] Fig. 2 is a configuration diagram showing the personal authentication information input device 4 and the camera 5 of Fig. 1. Fig. 2 also shows an authenticated person 6 who is about to enter and leave the entry and exit restricted area. The personal authentication information input device 4 and the camera 5 are provided corresponding to a door (not shown) provided on a boundary wall of the entry and exit restricted area.
[0019] The person to be authenticated 6 inputs personal authentication information identifying the person to be authenticated 6 to the personal authentication information input device 4. In this example, the personal authentication information identifying the person to be authenticated 6 is stored in a card 7 carried by the person to be authenticated 6. Therefore, the personal authentication information input device 4 is a non-contact card reader device that performs wireless communication with the card 7.
[0020] The person to be authenticated 6 brings the card 7 held by the person to be authenticated close to the personal authentication information input device 4. This causes wireless communication between the card 7 and the personal authentication information input device 4, and personal authentication information identifying the person to be authenticated 6 is input to the personal authentication information input device 4. The personal authentication information input to the personal authentication information input device 4 is defined as input personal authentication information.
[0021] The personal authentication information input device 4 is not limited to a contactless card reader device, and may be, for example, a numeric keypad device, a contact card reader device, a fingerprint information input device, or a face information input device. When the personal authentication information input device 4 is a numeric keypad device, the person to be authenticated 6 operates the numeric keypad device, so that personal authentication information identifying the person to be authenticated 6 is input to the numeric keypad device. When the personal authentication information input device 4 is a fingerprint information input device, the fingerprint information input device photographs the fingerprint of the person to be authenticated 6, and the photographed fingerprint image is input to the fingerprint information input device as personal authentication information identifying the person to be authenticated 6. When the personal authentication information input device 4 is a face image input device, the face image input device photographs the face of the person to be authenticated 6, and the photographed face image is input to the face image input device as personal authentication information identifying the person to be authenticated 6.
[0022] Camera 5 captures an image of person-to-be-authenticated 6 who brings card 7 close to personal authentication information input device 4. Thus, camera 5 captures an image of person-to-be-authenticated 6 who is attempting to enter or leave the entrance / exit restricted area.
[0023] The personal authentication information input to the personal authentication information input device 4 is input to the electric lock control device 2. The image captured by the camera 5 is input to the electric lock control device 2.
[0024] As shown in FIG. 1, the electric lock control device 2 includes an electric lock control device main body 201, a motion detection device 202, and a determination device 203.
[0025] The electric lock control device main body 201 controls the operation of the electric lock 3. When the electric lock control device main body 201 locks the electric lock 3, the electric lock control device main body 201 inputs a locking signal to the electric lock 3. When the electric lock control device main body 201 unlocks the electric lock 3, the electric lock control device main body 201 inputs an unlocking signal to the electric lock 3.
[0026] The image captured by camera 5 is input to motion detection device 202. Motion detection device 202 detects a plurality of motions of person to be authenticated 6 using the image captured by camera 5. Information on the plurality of motions of person to be authenticated 6 detected by motion detection device 202 is regarded as detected plurality of motion information.
[0027] Information on a plurality of movements of person to be authenticated 6 detected by movement detection device 202 is input to determination device 203 .
[0028] The determination device 203 determines whether or not the personal authentication information of the person to be authenticated 6 input to the personal authentication information input device 4 matches the personal authentication information registered in advance in a table stored in the storage device 101. In other words, the determination device 203 determines whether or not the input personal authentication information matches the registered personal authentication information.
[0029] The determination device 203 determines whether or not information on a plurality of movements of the person to be authenticated 6 detected by the movement detection device 202 matches information on a plurality of movements pre-registered in a table stored in the storage device 101 in correspondence with the personal authentication information input to the personal authentication information input device 4. In other words, the determination device 203 determines whether or not the detected plurality of movements matches registered plurality of movements information corresponding to the personal authentication information input to the personal authentication information input device 4.
[0030] The electric lock control device main body 201 controls the operation of the electric lock 3 based on the judgment result of the judgment device 203. Therefore, the electric lock control device 2 controls the operation of the electric lock 3 using the personal authentication information input to the personal authentication information input device 4 and the personal authentication information and information on a plurality of operations that are registered in advance in a table in correspondence with each other.
[0031] The memory device 101 stores a personal authentication information input history indicating the history of personal authentication information input to the personal authentication information input device 4, and a motion detection history indicating the history of multiple motions of the person to be authenticated 6 detected by the motion detection device 202, in correspondence with each other.
[0032] FIG. 3 is a diagram showing a plurality of movements of the person to be authenticated 6 detected by the movement detection device 202 of FIG. 1. The movement detection device 202 detects a plurality of types of hand shapes of the person to be authenticated 6 made in sequence as a plurality of movements of the person to be authenticated 6. In this example, the movement detection device 202 detects three types of hand shapes of the person to be authenticated 6 made in sequence as a plurality of movements of the person to be authenticated 6. In FIG. 3, a hand shape with only the index finger extended is detected as the first hand shape, a hand shape with all five fingers extended is detected as the second hand shape, and a hand shape with only the index finger, middle finger, and ring finger extended is detected as the third hand shape. The information on the first detected hand shape, the information on the second detected hand shape, and the information on the third detected hand shape are associated with each other to obtain information on a plurality of movements of the person to be authenticated 6.
[0033] In addition, the multiple movements of the person to be authenticated 6 detected by the movement detection device 202 are not limited to multiple types of hand shapes of the person to be authenticated 6 made in sequence, but may be multiple types of shapes of specific parts of the person to be authenticated 6 made in sequence.
[0034] As shown in FIG. 1, the electric lock 3 includes an electric lock main body 301, an electric lock driving device 302, an electric lock state detection device 303, and a door opening / closing detection device 304.
[0035] The electric lock body 301 is a member for locking the door. The electric lock body 301 moves between a locked position where the door is locked and an unlocked position where the door is unlocked.
[0036] The electric lock driving device 302 moves the electric lock main body 301. The driving of the electric lock driving device 302 is controlled by the electric lock control device main body 201 of the electric lock control device 2. When a locking signal is input from the electric lock control device main body 201 to the electric lock driving device 302, the electric lock driving device 302 sets the position of the electric lock main body 301 to the locked position. On the other hand, when an unlocking signal is input from the electric lock control device main body 201 to the electric lock driving device 302, the electric lock driving device 302 sets the position of the electric lock main body 301 to the unlocked position.
[0037] The electric lock status detection device 303 detects the position of the electric lock main body 301. When the position of the electric lock main body 301 is the locked position, the electric lock status detection device 303 inputs locking status information indicating that the position of the electric lock main body 301 is the locked position to the electric lock control device main body 201. On the other hand, when the position of the electric lock main body 301 is the unlocked position, the electric lock status detection device 303 inputs unlocking status information indicating that the position of the electric lock main body 301 is the unlocked position to the electric lock control device main body 201.
[0038] When the electric lock main body 301 is in the unlocked position for a preset time, the electric lock control device main body 201 inputs a locking signal to the electric lock main body 301. As a result, when the electric lock main body 301 is in the unlocked position for a preset time, the electric lock main body 301 moves from the unlocked position to the locked position.
[0039] The door opening / closing detection device 304 detects the position of the door. The door moves between a closed position where the door closes the entrance and an open position where the entrance is open. When the door is in the closed position, the door opening / closing detection device 304 inputs door closed state information indicating that the door is in the closed position to the electric lock control device main body 201. On the other hand, when the door is in the open position, the door opening / closing detection device 304 inputs door open state information indicating that the door is in the open position to the electric lock control device main body 201.
[0040] When the electric lock main body 301 does not move due to a failure of the electric lock 3, the electric lock control device 2 inputs entry / exit restriction abnormality occurrence information indicating that an abnormality has occurred in the entry / exit restricted area to the center device 1. In addition, when the door remains in the open position for a preset time, the electric lock control device 2 inputs entry / exit restriction abnormality occurrence information indicating that an abnormality has occurred in the entry / exit restricted area to the center device 1.
[0041] Fig. 4 is a diagram showing a table stored in storage device 101 of Fig. 1. In the table, personal authentication information of person 6 who is permitted to enter and leave the entrance / exit restricted area is registered in advance. In addition, in the table, information on a plurality of actions of person 6 who is permitted to enter and leave the entrance / exit restricted area is registered in advance. The personal authentication information of person 6 and information on a plurality of actions of person 6 are registered in correspondence with each other.
[0042] The registered multiple action information corresponding to “A” of the registered personal authentication information is a hand shape in which the first hand shape is a hand shape with only the index finger extended, a hand shape in which all five fingers are extended, and a hand shape in which only the index finger, middle finger, and ring finger are extended.
[0043] The registered multiple action information corresponding to "B" of the registered personal authentication information is a hand shape in which the first hand shape has all five fingers extended, a hand shape in which only the index finger, middle finger and ring finger are extended, and a hand shape in which only the index finger is extended.
[0044] The registered multiple action information corresponding to "C" of the registered personal authentication information is a hand shape in which only the index finger, middle finger and ring finger are extended in the first hand shape, a hand shape in which only the index finger is extended in the second hand shape, and a hand shape in which all five fingers are extended in the third hand shape.
[0045] The registered multiple action information corresponding to “D” of the registered personal authentication information is a hand shape in which the first hand shape is a hand shape with only the index finger extended, a hand shape in which the second hand shape is a hand shape with only the index finger, middle finger and ring finger extended, and a hand shape in which all five fingers are extended.
[0046] Next, the operation of the personal authentication system will be described with reference to a flowchart shown in FIG 5.
[0047] First, in step S101, the personal authentication system performs a personal authentication information input process. In the personal authentication information input process, the person to be authenticated 6 brings the card 7 held by the person to be authenticated 6 close to the personal authentication information input device 4. As a result, the personal authentication information stored in the card 7 held by the person to be authenticated 6 is input to the personal authentication information input device 4.
[0048] After that, in step S102, the personal authentication system performs a personal authentication information registration determination step. In the personal authentication information registration determination step, the determination device 203 determines whether the personal authentication information input to the personal authentication information input device 4 matches the personal authentication information pre-registered in the table. In other words, the determination device 203 determines whether the input personal authentication information matches the registered personal authentication information.
[0049] In step S102, if the judgment device 203 determines that the personal authentication information input to the personal authentication information input device 4 does not match the personal authentication information pre-registered in the table, the operation of the personal authentication system ends with the electric lock 3 remaining locked.
[0050] On the other hand, in step S102, if the determination device 203 determines that the personal authentication information input to the personal authentication information input device 4 matches the personal authentication information pre-registered in the table, the processing of the personal authentication system proceeds to step S103.
[0051] In step S103, the personal authentication system performs a multiple action detection process. In the multiple action detection process, first, camera 5 captures multiple actions of person-to-be-authenticated 6. In the multiple action detection process, action detection device 202 detects multiple actions of person-to-be-authenticated 6 using the images captured by camera 5.
[0052] After that, in step S104, the personal authentication system performs a multiple action information registration determination step. In the multiple action information registration determination step, the determination device 203 determines whether or not information on multiple actions of the person to be authenticated 6 detected by the action detection device 202 matches information on multiple actions pre-registered in a table corresponding to the personal authentication information input to the personal authentication information input device 4. In other words, the determination device 203 determines whether or not the detected multiple action information matches registered multiple action information corresponding to the personal authentication information input to the personal authentication information input device 4.
[0053] If the determination device 203 determines in step S104 that the detected multiple-motion information does not match the registered multiple-motion information, the electric lock 3 remains locked and the operation of the personal authentication system ends.
[0054] On the other hand, if the determination device 203 determines in step S104 that the detected multiple motion information matches the registered multiple motion information, the processing of the personal authentication system proceeds to step S105.
[0055] In step S105, the personal authentication system performs an electric lock unlocking process. In the electric lock unlocking process, electric lock 3 is unlocked. This allows person-to-be-authenticated 6 to enter and leave the entry / exit restricted area.
[0056] As described above, the personal authentication system according to the first embodiment includes a personal authentication information input device 4, a camera 5, a motion detection device 202, and a determination device 203. The personal authentication information of the person to be authenticated 6 is input to the personal authentication information input device 4. The camera 5 captures the person to be authenticated 6. The motion detection device 202 detects a plurality of motions of the person to be authenticated 6 using the video captured by the camera 5. The determination device 203 determines whether or not the plurality of motions of the person to be authenticated 6 detected by the motion detection device 202 match information on a plurality of motions preregistered in correspondence with the personal authentication information input to the personal authentication information input device 4. According to this configuration, the determination device 203 uses information on the plurality of motions of the person to be authenticated 6 to determine whether or not the person to be authenticated 6 is permitted to enter and leave the entry and exit restricted area. This can improve the security level of the personal authentication system compared to a case where whether or not the person to be authenticated 6 is permitted to enter and leave the entry and exit restricted area is determined using information on a single motion of the person to be authenticated 6.
[0057] Furthermore, in the personal authentication system according to the first embodiment, the multiple movements of the person to be authenticated 6 include multiple types of shapes of specific parts of the person to be authenticated 6 that are made in sequence. With this configuration, the multiple movements of the person to be authenticated 6 are detected by movement detection device 202 by moving only the specific parts of the person to be authenticated 6. This makes it possible to simplify the multiple movements of the person to be authenticated 6 and to reduce the possibility that the movements of the person to be authenticated 6 will be witnessed by a third party.
[0058] Furthermore, in the personal authentication system according to the first embodiment, the specific body part of person to be authenticated 6 is the hand of person to be authenticated 6. With this configuration, by moving only the hand of person to be authenticated 6, a plurality of movements of person to be authenticated 6 are detected by movement detection device 202. This can simplify the plurality of movements of person to be authenticated 6, and can further reduce the possibility that the movements of person to be authenticated 6 are witnessed by a third party.
[0059] The personal authentication system according to the first embodiment also includes a storage device 101. In the storage device 101, a personal authentication information input history indicating a history of personal authentication information input to the personal authentication information input device 4 and a motion detection history indicating a history of a plurality of motions of the person to be authenticated 6 detected by the motion detection device 202 are stored in correspondence with each other. With this configuration, an administrator can operate the center device 1 to retrieve information stored in the storage device 101, thereby enabling the administrator to check the personal authentication information input history and the motion detection history corresponding to the personal authentication information input history.
[0060] Embodiment 2 Fig. 6 is a configuration diagram showing a personal authentication system according to embodiment 2. The personal authentication system according to embodiment 2 further includes a secret box 8 into which a hand of a person to be authenticated 6 is inserted. In Fig. 6, personal authentication information input device 4 and camera 5 are omitted.
[0061] Camera 5 is placed inside secret box 8. Camera 5 captures the hand of person 6 who is to be authenticated, which is inserted inside secret box 8. By inserting the hand of person 6 who is to be authenticated inside secret box 8, multiple hand movements of person 6 who is to be authenticated are prevented from being witnessed by a third party.
[0062] Other configurations of the personal authentication system according to the second embodiment are similar to those of the personal authentication system according to the first embodiment.
[0063] As described above, the personal authentication system according to the second embodiment includes secret box 8 into which the hand of person to be authenticated 6 is inserted. Camera 5 captures an image of the hand of person to be authenticated 6 inserted inside secret box 8. This configuration makes it possible to prevent multiple hand movements of person to be authenticated 6 from being witnessed by a third party.
[0064] The personal authentication system may include a notification device that notifies the person to be authenticated 6 of the determination result of determination device 203. In this case, the notification device may notify the person to be authenticated 6 of the determination result of determination device 203 as to whether or not the personal authentication information input to personal authentication information input device 4 matches the personal authentication information permitted to enter and leave the entry and exit restricted area. The notification device may also notify the person to be authenticated 6 of the determination result of determination device 203 as to whether or not the detected multiple motion information matches the registered multiple motion information.
[0065] Furthermore, the personal authentication system may include a notification device that notifies the person to be authenticated 6 that a motion has been detected each time motion detection device 202 detects each of a plurality of motions of person to be authenticated 6 in sequence. This allows the person to be authenticated 6 to know whether or not one of the plurality of motions performed by person to be authenticated 6 has been detected by motion detection device 202. As a result, person to be authenticated 6 can perform the next motion.
[0066] In each embodiment, a personal authentication system used when the person to be authenticated 6 enters and leaves an entry-restricted area has been described. However, the personal authentication system may be used not only when the person to be authenticated 6 enters and leaves an entry-restricted area, but also when identifying the person to be authenticated 6.
[0067] Also, in each embodiment, a configuration has been described in which the multiple actions of the person to be authenticated 6 include the shapes of multiple types of specific body parts of the person to be authenticated 6, which are made in sequence. However, the multiple actions of the person to be authenticated 6 are not limited to the shapes of specific body parts of the person to be authenticated 6, and may also include the shapes of possessions held by the person to be authenticated 6. Examples of possessions held by the person to be authenticated 6 include a key holder and a watch. [Explanation of symbols]
