It is an example which showed the movement path | route of the user of embodiment which concerns on this invention. It is a sequence diagram which shows the whole flow of the image security system of embodiment which concerns on this invention.

  The image security system according to the present embodiment acquires movement path information of a moving body set in advance based on image information from a plurality of cameras installed in a distributed manner, and the movement path information is set in advance. A check is made with the release code corresponding to the information to determine whether it is valid. According to this, since there is no possibility that the release key for releasing the security is lost or stolen, a high security effect can be achieved. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  First, the configuration of the image security system 1000 will be described with reference to FIG. The image security system 1000 includes an imaging information recording unit 10 that captures and records a predetermined space, an authentication control unit 20 that performs authentication based on image information of a user who has made an authentication request, and an authentication request from the user. The user interface unit 30 accepts and releases the electronic lock according to the authentication result.

  The imaging information recording unit 10 and the user interface unit 30 are connected to the authentication control unit 20 via a private network 40. However, the imaging information recording unit 10, the user interface unit 30, and the authentication control unit 20 are not limited to connection through the private network 40, and may be in a connection form in which the respective arrangement bases are not limited.

  For example, a configuration in which the photographing information recording unit 10, the user interface unit 30, and the authentication control unit 20 are connected via a public network, and a configuration in which wireless communication is used for the connection between the user interface unit 30 and the authentication control unit 20 are also possible. Is possible. Further, a camera 11 (described later) of the photographing information recording unit 10 and an image storage device 12 may be connected wirelessly.

  The photographic information recording unit 10 includes a plurality of cameras 11-1 to 11-n (hereinafter, each camera is collectively referred to as a camera 11) and a plurality of image storage devices 12-1 to 12-12 that store images captured by the camera 11. -N (hereinafter, each image storage device is collectively referred to as an image storage device 12). Each camera 11 is installed in a distributed manner at a plurality of bases, and is set to shoot different shooting areas.

  For example, FIG. 2 is an example in which the image security system 1000 of the present embodiment is applied to an office in one floor. FIG. 2 shows an office in which a plurality of rooms exist on one floor surrounded by a wall represented by a black frame. As an example, each office room is “Reception (2001)”, “Reception Room 1 (2002)”, “Reception Room 2 (2003)”, “Conference Room (2004)”, “Warehouse (2005)”, “Confidential” Document Storage (2006), President Office (2007), Secretary Room (2008), Server Room (2009), Toilet (2010), Waiting Room (2011), Office ( 2012) ”and“ Design Room (2013) ”.

  In this office, nine cameras 11 are distributed and installed. Here, nine cameras 11 are represented by cameras 1 to 9, respectively, and areas captured by the cameras 11 are represented by imaging areas 1 to 9. Each camera 11 is set to monitor a different area. For example, the camera 1 is set to take a picture of the shooting area 1, and the camera 2 is set to take a shot of the shooting area 2. Each camera 11 may be configured to change the shooting direction as necessary.

  Returning to FIG. 1, each camera 11 is assigned a unique camera ID for identifying the camera 11. Image information photographed by each camera 11 is stored in the image storage device 12 in association with the photographing time and the camera ID of the camera 11 where the photographing was performed. The image information recorded by the photographing information recording unit 10 is used by the authentication control unit 20 (to be described later) to generate a moving path of a predetermined moving body. This moving route is recognized depending on which shooting area is used for shooting. Although FIG. 1 shows an example in which each camera 11 and each image storage device 12 have a one-to-one relationship, the number of cameras 11 and image storage devices 12 may be other than one-to-one.

  The user interface unit 30 corresponds to personal information input devices 31-1 to 31-m that accept authentication requests from users (hereinafter, each personal information input device is generically referred to as the personal information input device 31) and the authentication result. The electronic lock devices 32-1 to 32-m that release the electronic lock (hereinafter, each electronic lock device is collectively referred to as an electronic lock device 32). The personal information input device 31 and the electronic lock device 32 have a one-to-one correspondence. The personal information input device 31 accepts input of personal information for identifying the user when accepting an authentication request from the user.

  Personal information may be anything that can identify the user, such as a personal identification code (password), physical features (fingerprint, vein, retina, face, voice, footsteps, smell, DNA, handwriting, etc.). Applicable. For example, the user may directly input a personal identification code into the personal information input device 31 via a numeric keypad or the like, or a personal identification code previously stored in a key or a card is brought into contact with the input unit of the personal information input device 31. The personal identification code may be wirelessly transmitted to the personal information input device 31 using a mobile phone or a non-contact electronic key.

  FIG. 3 is a device configuration example of the user interface unit 30. Here, it is assumed that security is applied to the entrance of the “confidential document storage (2006)” shown in FIG. The door lever 321 of the room whose room name is a confidential document storage is equipped with an electronic lock device 32, and the electronic lock is released and the door lever 321 is released only when it is authenticated through the network 40 as a valid user. Is controlled to open and the door 322 is opened. The personal information input device 31 is provided in the vicinity of the electronic lock device 32, and is installed on the wall located beside the door 322 of the confidential document storage (2006), for example.

  The personal information input device 31 includes a status display unit 311, a personal information input unit 312, and a door lock release switch 313. Here, description will be made assuming that personal information is notified to the authentication control unit 20 by the face recognition technology. Therefore, the personal information input unit 312 includes a photographing camera 3121 for photographing a user's face and a photographed image display 3122 for displaying a photographed face image.

  When the user makes an authentication request, the user presses the door lock release switch 313. Thereby, the personal information input device 31 switches the display on the status display unit 311 from non-display to display indicating that the photographing process is being performed, and causes the photographing camera 3121 to photograph the user's face and displays the photographed image on the photographed image display. 3122 is displayed. The user can confirm whether or not the photographing camera 3121 is directly facing by confirming the photographed image display 3122.

  When the photographing is finished, the personal information input device 31 acquires the acquired personal information (user's face image) and identification information of the electronic lock device 32 that requests unlocking (for example, a room name equipped with the electronic lock device 32, etc.). Are sent to the authentication control unit 20 via the network 40. In addition, the personal information input device 31 switches the display of the status display unit 311 to a display indicating that the electronic lock release permission determination process is being performed. When the release permission determination process is completed and the release is permitted via the network 40, the personal information input device 31 displays a message indicating unlocking on the status display unit 311 and releases the electronic lock. On the other hand, if the release is not permitted as a result of the release permission / inhibition determination process, the personal information input device 31 causes the status display unit 311 to display a lock release refusal and does not release the electronic lock.

  Returning to FIG. 1, the authentication control unit 20 will be described. The authentication control unit 20 includes an authentication processing unit 21 and a user information storage unit 22.

  The user information storage unit 22 stores various information associated with personal information, and includes a personal ID storage device 221, a movement path key storage device 222, and a key image storage device 223. Here, although the personal ID storage device 221, the movement path key storage device 222, and the key image storage device 223 are configured separately, they may be configured as a single storage device by associating the respective storage contents.

  The personal ID storage device 221 stores preset personal information collated with personal information input by the user in the personal information input device 31 in association with a personal ID uniquely assigned to each user. As described above, for example, a personal identification code (password), physical characteristics (fingerprint, vein, retina, face, voice, footsteps, smell, DNA, etc.) can be applied as the personal information.

  The movement path key storage device 222 stores movement path information (hereinafter referred to as a movement path key) of a predetermined moving body used as a release key for releasing the lock of the electronic lock device 32. The movement path key is stored in association with the personal ID and the identification information of the electronic lock device 32. For example, it is possible to restrict users who can release the electronic lock in each room controlled by the electronic lock device 32, and to set different movement path keys for each user. Therefore, even in the same room, if the personal ID is different, it is possible to make the electronic lock impossible to release even if the same route is followed. In the present embodiment, the identification information of the electronic lock device 32 will be described as a room name whose opening / closing of the door 322 is controlled by the electronic lock device 32.

  FIG. 4 is an image diagram showing a state in which a certain movement path key is registered in the movement path key storage device 222. Here, as an example, the room name “confidential document storage”, the personal ID “international Taro”, and the shooting area number list indicating the movement route key are associated and managed.

  The shooting area number list is a list format in which shooting area numbers that are the shooting ranges of the cameras 11 of the shooting information recording unit 10 are arranged in a predetermined order. In other words, the movement route key is configured by the shooting area numbers arranged in a predetermined order. In FIG. 4, the shooting area numbers are arranged in the order of “9” “8” “7” “6” “5” “4” “5” “6” “1” “2”. List numbers (No.) 1 to 10 are assigned to the numbers. A larger list number means that the time passing through the shooting area corresponding to the list number is older. That is, for example, the shooting area “2” corresponding to the list number “10” is an area that first passes through a series of travel routes. Here, the movement path key is configured by the shooting area number, but it is only necessary to identify each shooting area. For example, the movement path key may be configured by a camera ID corresponding to the shooting area number.

  FIG. 5 is a diagram showing a movement route corresponding to the movement route key shown in FIG. Here, the camera 11 that shoots each shooting area is omitted. The moving path keys shown in FIG. 4 are the shooting area numbers “2”, “1”, “6”, “5”, “4”, “5”, “6”, “7”, “8”, and “9” from the oldest shooting time. is there. Therefore, in the office layout in FIG. 5, the shooting area 2 is the first start point of the movement route. For example, when a predetermined moving body is set as a user, the user moves in the order of the shooting area 2 → the shooting area 1 → the shooting area 6 → the shooting area 5 → the shooting area 4 and makes a U-turn in the shooting area 4. Then, when moving forward in the order of the shooting area 5 → the shooting area 6 → the shooting area 7 → the shooting area 8 → the shooting area 9, it means that the same movement route as the movement route key has been moved. Note that the movement route key may be set based on a movement route not only within one floor but also over multiple floors and multiple facilities.

  Returning to FIG. 1, the key image storage device 223 stores a key image that is an image of a moving body that moves along the movement path. The key image serves as a reference for searching for an image of the moving body from the captured image stored in the image storage device 12 of the captured information recording unit 10. The key image storage device 223 stores the key image in association with the personal ID. In the following description, it is assumed that the predetermined moving body that moves along the movement path is a user. In this case, the key image may be a user's face image, for example.

  The authentication processing unit 21 includes an authority verification unit 211, an image search unit 212, a movement route generation unit 213, and a release determination unit 214.

  The authority verification unit 211 refers to the personal ID storage device 221 for personal information acquired via the personal information input device 31 and performs verification of the personal information. Here, any method may be used as long as an individual can be identified. When the personal information acquired via the personal information input device 31 matches the personal information stored in the personal ID storage device 221, the authority verification unit 211 is associated with the personal information stored in the personal ID storage device 221. Obtain a personal ID. If the personal information does not match, the authority verification unit 211 returns an authentication error to the personal information input device 31 via the network 40, assuming that the user who issued the authentication request does not have the authority to unlock.

  Further, the authority verification unit 211 refers to the travel route key storage device 222 and acquires the travel route key corresponding to the personal ID. At this time, if the authority verification unit 211 cannot acquire the movement route key, the authority verification unit 211 determines that the user does not have the authority to unlock, and returns an authentication error to the personal information input device 31 via the network 40. The authority verification unit 211 outputs the acquired personal ID and movement path key to the image search unit 212.

  The image search unit 212 refers to the key image storage device 223 and acquires a key image corresponding to the personal ID acquired by the authority verification unit 211. The image search unit 212 searches for a captured image stored in the image storage device 12 based on the key image. Specifically, the image search unit 212 analyzes the key image, extracts the feature amount of the key image, and searches the image storage device 12 for an image similar to the feature amount. As a result, the image search unit 212 collects images taken by the user with each camera 11 from each image storage device 12 and outputs them to the movement path generation unit 213 together with the movement path key. As a technique for searching for similar images based on key images, a known technique can be used.

  The movement route generation unit 213 generates user movement route information based on a plurality of images acquired from the image search unit 212. Specifically, first, the movement path generation unit 213 rearranges a plurality of images in time series in order of shooting time. As a result, the images are rearranged in the order of movement of the user. Next, based on the camera ID associated with each image, the movement path generation unit 213 includes movement path information configured by shooting area numbers in a predetermined order based on the shooting area numbers assigned to the cameras 11 of the respective camera IDs. And is output to the release determination unit 214 together with the movement path key acquired from the image search unit 212.

  FIG. 6 is an example showing a user's travel route. Here, when the user leaves the conference room (2004), the user moves from shooting area 4 to shooting area 3 → shooting area 2 → shooting area 1 → shooting area 6 → shooting area 5 and makes a U-turn in shooting area 5. Returning, the shooting area 6 → the shooting area 7 → the shooting area 8 → the shooting area 9 is moved to the front of the confidential document storage (2006) which is electronically locked by the electronic lock device 32.

  At this time, the movement route generation unit 213 starts from the oldest time in a series of shooting areas “4”, “3”, “2”, “1”, “6”, “5”, “6”, “7”, “8”, and “9”. The movement route information by the number of is generated.

  The movement route information generated by the movement route generation unit 213 is collated by the release determination unit 214. The release determination unit 214 compares the movement route information and the movement route key, authenticates that the user is a valid user if they match, and releases a release signal for releasing the lock and allowing the electronic lock device 32 to be released. To the electronic lock device 32. Also, the release determination unit 214 displays a message indicating unlocking on the status display unit 311 of the personal information input device 31 via the network 40 and prompts the user to open the door 322. Here, the fact that the movement route information matches the movement route key means that all the movement route keys are included in the movement route information.

  On the other hand, when the movement route information and the movement route key are different, the release determination unit 214 determines that the user is an unauthorized user. In this case, the release determination unit 214 does not output a release signal to the electronic lock device 32, and causes the status display unit 311 of the personal information input device 31 to display a message indicating that lock release is rejected via the network 40.

  For example, a user “Taro Kokusai” has the authority to release the electronic lock of “Secret Document Storage (2006)” on the office layout shown in FIG. 5, and the movement route shown in FIG. Assume that the key has been set.

  In order to release the electronic lock of the “confidential document storage (2006)” from the “international Taro”, the process from the “conference room (2004)” to the “confidential document storage (2006)” is described above with reference to FIG. It is assumed that the travel route shown in FIG. In this case, the movement route information generated by the movement route generation unit 213 is “4” “3” “2” “1” “6” “5” “6” “7” “8” “9”. The preset movement route keys “2” “1” “6” “5” “4” “5” “6” “7” “8” “9” do not match. This is because “Taro Kokusai” in FIG. 6 should have returned from the shooting area 5 to the shooting area 4, but turned back before moving to the shooting area 4. Therefore, the release determination unit 214 determines that “Taro Kokusai” is an unauthorized user and does not release the electronic lock of “confidential document storage (2006)”.

  If “Taro Kokusai” releases the electronic lock of “Confidential Document Storage (2006)” from “Conference Room (2004)” to “Confidential Document Storage (2006)”, the shooting area 4 → Shooting area 3 → Shooting area 2 → Shooting area 1 → Shooting area 6 → Shooting area 5 → Shooting area 4 U-turn in shooting area 4 and turning back, Shooting area 5 → Shooting area 6 → Shooting area 7 Suppose that the shooting area 8 → the shooting area 9 proceed. In this case, the movement route information generated by the movement route generation unit 213 is “4” “3” “2” “1” “6” “5” “4” “5” “6” “7” “8”. “9”, which matches the set travel route key “2” “1” “6” “5” “4” “5” “6” “7” “8” “9”. Therefore, the release determination unit 214 determines that “Taro Kokusai” is a legitimate user, and releases the electronic lock of “confidential document storage (2006)”.

  Next, an overall flow in the image security system 1000 will be described with reference to FIG.

  First, when the user moves in front of the door 322 desired to enter the room, the plurality of cameras 11 are determined in advance so that the movement route corresponds to the movement route key stored in the movement route key storage device 222 in advance. Move to shoot in order. As the user moves as described above, the image information captured by each camera 11 corresponding to the movement path of the user is stored in the image storage device 12 (step A10). In other words, the image storage device 12 stores “what route the user has traveled”.

  The user who has moved in front of the door 322 to enter the room inputs personal information for identifying himself / herself to the personal information input device 31 (step A20). The personal information input device 31 includes the acquired personal information and the identification information of the electronic lock device 32 related to the door 322 that the user desires to enter into the authentication request, and notifies the authentication control unit 20 via the network 40 (step A30). ).

  The authority collation unit 211 collates the personal information included in the authentication request with the personal information in the personal ID storage device 221 (step A40). When the personal information included in the authentication request is different from the personal information in the personal ID storage device 221 (No in step A40), the authority verification unit 211 returns an authentication error to the personal information input device 31 via the network 40, and the electronic information The unlocking procedure is stopped (step A50). On the other hand, when the personal information matches, the authority verification unit 211 acquires a personal ID corresponding to the personal information from the personal ID storage device 221 (step A60).

  Next, the authority verification unit 211 refers to the movement path key storage device 222 and acquires a movement path key corresponding to the personal ID and the identification information of the electronic lock device 32 (Yes in Step A70). On the other hand, if the authority verification unit 211 cannot acquire the movement path key corresponding to the personal ID and the identification information of the electronic lock device 32 (No in step A70), the authority collating unit 211 determines that the user does not have the authority to release the lock. Then, an authentication error is returned to the personal information input device 31 and the electronic unlocking procedure is stopped (step A80).

  As described above, the authority verification unit 211 performs the authority verification process not only in step A40 but also in step A70. It is possible to set a user who can release it for each door 322 that is electronically locked. This is because. That is, just because a person's identity can be verified by collating personal information in step A40, the person does not necessarily have the authority to release the electronic lock of the door 322.

  Next, the image search unit 212 refers to the key image storage device 223 and acquires a key image associated with the personal ID (step A90). Then, the image search unit 212 searches the plurality of image storage devices 12 of the photographing information recording unit 10 for an image similar to the key image (step A100). Here, the image similar to the key image refers to an image in which the same person as the user in the key image is captured. Further, the image search unit 212 may search for images taken in a predetermined time period in consideration of the time for the user to move along the movement route. Next, the image search unit 212 makes a transmission request for an image corresponding to the search result to the plurality of image storage devices 12 (step A110). The image search unit 212 acquires the corresponding image from the plurality of image storage devices 12 and outputs it to the movement route generation unit 213 together with the movement route key acquired from the authority verification unit 211 (step A120).

  The movement route generation unit 213 generates movement route information based on the time information attached to the image corresponding to the key image and the camera ID, and outputs the movement route information together with the movement route key to the release determination unit 214 (step A130).

  The release determination unit 214 compares the movement route information and the movement route key, and if the movement routes match (Yes in Step A140), notifies the electronic lock device 32 of a release signal (Step A150). When the electronic lock device 32 acquires the release signal, the electronic lock device 32 releases the lock of the door 322 on which the electronic lock is applied (step A160). On the other hand, when it is determined that the movement route is different (No in Step A140), the cancellation determination unit 214 notifies the personal information input device 31 of an authentication error (Step A170). At this time, since the release determination unit 214 does not notify the electronic lock device 32 of the release signal, the electronic lock is not released.

  As described above, in this embodiment, the electronic lock is set in advance for the door 322 of the predetermined room that is electronically locked by the cooperative operation of the photographing information recording unit 10, the authentication control unit 20, and the user interface unit 30. The electronic lock can be released only when a person who has been permitted to release is followed a predetermined movement route. As a result, a third party who tries to intrude into the room cannot unlock the electronic lock with a key, password, or the like, so that the security performance can be improved.

  Further, in this embodiment, by performing explicit personal authentication on the personal information input device in front of the door 322 that is electronically locked, an implicit release key that is a movement path until personal authentication is performed can be camouflaged. This makes it difficult for a third party to perceive the presence of the release key. That is, it is preferable that the release key is at least a point where the personal information input device is installed at the final point of the movement route.

  In the present embodiment, the mobile object that moves along the predetermined movement route is described as the user. However, the mobile object may be a person or an object different from the user. In this case, when the user performs personal authentication with the personal information input device, the release determination is made by comparing the movement route information within a predetermined time and the movement route key for a person or object determined as a moving object. Good.

  Further, in the present embodiment, the object to be electronically locked is described as the room door 322, but it can be applied if the object to be electronically locked requires a key, for example, an automobile, a safe or a locker. You may comprise so that the electronic lock of a door may be cancelled | released.

  Further, the present embodiment may be applied to predetermined information (for example, data, folder, network 40, etc.) to which security is applied. In this case, when personal authentication is performed with a login password input to the information processing apparatus for accessing the predetermined information, and the movement path to the information processing apparatus matches the release key, the security for the predetermined information is It may be canceled and access to the information may be permitted.

As described above, when this embodiment is outlined, the image security system of this embodiment is an image security system that performs authentication based on image information from an imaging unit that images a predetermined space, and is a plurality of distributedly installed image security systems. The imaging means, route acquisition means for acquiring movement route information of a predetermined moving body from the image information imaged by the plurality of imaging means, the movement route information and preset predetermined movement route information. It is characterized by comprising authentication means for authenticating that the two match.
An authority collation unit that performs personal authentication by collating input personal information with preset personal information may be provided, and the predetermined movement route information may be associated with the preset personal information.
Moreover, you may provide the electronic lock means which unlocks an electronic lock, when it authenticates with authentication means.
