<P>PROBLEM TO BE SOLVED: To provide a system for detecting suspicious objects, which can detect the setting of spy cameras before such crimes occur as uses magnetic or IC cards, or personal identification numbers filmed by spy cameras, and can image a prowler who behaves unnaturally as if making transactions, without imaging personal information such as personal identification numbers inputted at normal transactions. <P>SOLUTION: A surveillance camera images a front panel of an ATM, where a card surface and a personal identification number input operation are liable to secret filming, and the surroundings thereof to automatically detect suspicious objects on the basis of differences between images captured periodically between a transaction end and the next transaction start according to ATM transaction information, and to monitor for the setting of suspicious objects. The surveillance camera images the front panel between a transaction end and the next transaction start, but stops imaging the front panel between the transaction start and the transaction end. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a system for detecting a suspicious object by photographing an automated cash transaction apparatus (Automated-Teller-Machine, hereinafter abbreviated as ATM) with a monitoring camera.

  Conventionally, when a user makes a cash transaction at an ATM, the identity of the card is verified by using a card and a password, but the information on the card surface and the password from the back of the user who is currently trading at the ATM are being used. Called out with a poster with a text that seems to be fraudulent, such as a device that can steal numbers, fraudulently read a card information or a wireless camera for voyeur camouflage and attach it to an ATM. However, crimes have frequently occurred, such as finding out account numbers and PINs from people who contacted them by mistake, and posting phishing posters. On the other hand, the installation of surveillance cameras to monitor suspicious behavior in financial institution stores and the installation of cameras that shoot people inside ATMs are trying to find suspicious people and suppress the occurrence of crime. .

  In Patent Document 1, when a plurality of ATMs are monitored by a single surveillance camera installed in a store, an ATM to which special attention should be paid is determined, and image data of a suspicious person is missed. A system for disabling is disclosed. Further, Patent Document 2 discloses a system in which the supervisor side determines whether an alarm is issued based on the degree of suspicious movement by analyzing the movement of another person who has entered the area during the ATM operation.

  In addition, in order to detect voyeurism with a wireless camera, a surveillance system for voyeur cameras that detects radio waves emitted from the wireless camera and reports it to a monitoring center has been announced as a product.

  As with conventional technologies, surveillance cameras always monitor suspicious behavior in order to record the shooting of suspicious persons, and respond to crimes by having data on all transactions. Thus, when it takes time from the occurrence of a crime to the occurrence of damage, the amount of information and the like becomes enormous, and it takes time and effort to search for illegal information that leads to the crime.

  Also, if the voyeur camera records in the large internal memory instead of wireless, or the detection of phishing posters, etc., if the transaction is performed on an ATM, the wireless monitoring or suspicious behavior monitoring is sufficient. I can not cope.

  Take a picture of the ATM front panel and its surroundings with a surveillance camera, where the card surface and PIN code input operation is easy to be sneak shot, and at a certain time interval from the end of the transaction to the start of the next transaction based on the ATM transaction information The suspicious object is automatically detected based on the difference between the images taken in step 1 and monitored so that the suspicious object is not installed. The front panel by the monitoring camera is photographed from the end of the transaction to the start of the transaction, and the photographing of the front panel by the monitoring camera is stopped from the start of the transaction to the end of the transaction.

  It is possible to find out the installation of the voyeur camera and prevent the crime before the crime using the magnetic or IC card or personal identification number photographed by the voyeur camera is performed. Also, by sharing card insertion / ejection information with ATMs, you can shoot a suspicious person who imitates a transaction and behaves suspiciously without having to shoot personal information such as a personal identification number entered during normal transactions. It becomes possible to do.

  Examples of the present invention are shown below.

  The external view of the suspicious object detection system of a present Example is shown in FIG. This system includes an ATM 101 to be monitored, a card mechanism unit 102 for reading information of a magnetic or IC card built in the ATM 101, a monitoring camera 103 built in a position where the front panel of the ATM 101 can be photographed, and a user using the ATM 101. From the monitoring device 104 that detects the suspicious object by controlling the start / stop of the photographing of the monitoring camera 103 by detecting the card insertion / ejection information to the card mechanism 102. The ATM control unit 105 that controls the ATM 101 in response to the alarm output and the monitoring computer 107 on the center side of the financial institution that receives the alarm output from the monitoring device 104 and performs the final determination of the suspicious object, the monitoring computer 107 and the monitoring device 104 are connected. Line cable 106 to be used, accepting input from the user Display input unit 108 such as a touch panel that displays guidance or the like, and a.

  The card described below may be any electronic medium that can be configured, such as a magnetic card, an IC card, or an RFID tag.

  FIG. 2 is a block diagram of the suspicious object detection system.

  The ATM 101 includes an ATM control unit 105, a monitoring device 104, a card mechanism unit 102, a monitoring camera 103, and a card detection unit 208 that detects that a card has been inserted into the card mechanism unit 102.

  The monitoring device 104 includes a control unit 201 that controls the entire monitoring device 104, a card mechanism control unit 202 that controls the card mechanism unit 102, a monitoring camera control unit 203 that controls start / stop of the monitoring camera 103 and image transfer, When a suspicious object is detected by the suspicious object detection unit 204 for detecting a suspicious object from the image on the front panel of the ATM 101, the suspicious object warning is displayed to the ATM control unit 105 by voice guidance or display. A warning unit 205 that issues a command, a communication unit 206 that transmits an image of an alarm or a suspicious object via the line cable 106, and an image storage unit 207 that stores an image for detecting a suspicious object are provided.

  A mechanism for detecting a suspicious object by the suspicious object detection unit 204 will be described with reference to FIG. A basic image 310 to which a suspicious object such as a voyeur camera or a phishing poster is not attached is acquired in advance by the monitoring camera 103. The suspicious object detection system according to the present embodiment interrupts shooting by the monitoring camera 103 while the user is dealing. When the user finishes the transaction, the surveillance camera 103 is activated to Start acquisition. Then, the user compares the image 311 obtained after the transaction is completed with the basic image 310, detects a portion having a large difference in image change as the suspicious object 301, stores the image 312 in the image storage unit 207, and detects the suspicious object. The alarm is transmitted to the monitoring computer 107.

  The detection procedure when the suspicious object 301 is attached to the ATM 101 will be described below with reference to FIGS.

  First, there is no suspicious object 301 with a voyeur camera installed on the card insertion slot on the front panel of the ATM 101 or above it, and there are no posters etc. leading to phishing fraud etc. And the basic image 310 is captured by the monitoring camera 103. This image is stored in the image storage unit 207 of the monitoring device 104 as a basic image 310 for detecting the suspicious object 301 at each subsequent transaction end at the ATM 101 or compared with an image at the time of no transaction. .

  In the monitoring camera 103, the user inserts the card 401 into the card mechanism unit 102 of the ATM 101, the card detection unit 208 detects the card 401, and the monitoring device 104 detects the start of transaction of the ATM 101 and takes a picture of the monitoring camera 103. Until it is stopped, images are taken at regular intervals to detect suspicious objects on the front panel of the ATM 101.

  When the card detection unit 208 detects that the card 401 has been inserted into the ATM 101, the monitoring device 104 determines that the transaction of the user has started, stops the shooting operation of the monitoring camera 103, and displays a monitoring camera image (card insertion) ) When nothing is displayed as in 410, an image relating to personal information such as the input of the user's personal identification number and deposit / withdrawal amount is not left. As a result, it is possible to prevent leakage of personal information by bank employees of financial institutions.

  When the card detection unit 208 detects that the card 401 has been ejected from the ATM 101, the monitoring device 104 determines that the transaction of the user has ended, and causes the monitoring camera 103 to start shooting again. At this time, an image of the front panel of the ATM 101 is taken as a monitoring camera image (at the time of card ejection) 510 and transmitted to the monitoring device 104, and suspicious object detection is performed.

  The suspicious object detection unit 204 compares the image data of the basic image 310 and the image 311 at the end of the transaction or at regular intervals as described above, and regards the difference in data as the suspicious object 301. In the monitoring apparatus 104 according to the present embodiment, a portion where the data difference of the suspicious object 301 exceeds a certain value (threshold value) is regarded as a suspicious object candidate 601. After that, even if an image that has passed for a certain period of time continues to have a data difference at the same position, it is regarded as a suspicious object 301.

  When the suspicious object candidate 601 is detected in the suspicious object detection image 610 after the transaction of the ATM 101, first, the monitoring device 104 determines that the suspicious object candidate 601 is a forgotten thing of the user who has transacted with the ATM 101 immediately before the monitoring camera 103 captures the image. A command is sent to the ATM control unit 105 so as to display the voice guidance of “forgotten things” or “removal of unwanted items” and an ATM attention display screen 611 (FIG. 6) on the display input unit 108, and the transaction is executed immediately before. The user who made the call is alerted and the suspicious object candidate 601 is removed.

  After this, if the suspicious object candidate 601 is removed from the suspicious object detection image 610 of the monitoring camera 103 after a certain time, the monitoring apparatus 104 uses the voice guidance “Attention of forgotten things” or “removing unnecessary objects” or ATM 101. The display of the caution display screen 611 is ended, and the suspicious object detection by the image of the monitoring camera 104 is executed again after the end of the next transaction or every predetermined time.

  Even if the voice guidance and screen display of the ATM 101 are implemented as shown in FIG. 7, if the suspicious object candidate 601 is detected at the same position in the suspicious object detection image 710 of the monitoring camera 103 after a certain period of time, the monitoring apparatus 104 is suspicious. The object candidate 601 is determined to be the suspicious object 301, and the supervisor and the guard who operates the monitoring computer 107 on the center side through the line cable 106 to perform the final determination of the suspicious object 301 are detected by the monitor and the security guard. An alarm and a suspicious object detection image 710 are transmitted. At the same time, the user who uses the ATM 101 is warned of the suspicious object (notifying that the transaction has been stopped because the suspicious object is installed), and a warning display 711 is displayed on the display input unit 108 by voice guidance. A command is transmitted to the ATM control unit 105 so as to do so. The ATM control unit 105 receives the command, performs voice guidance, displays an ATM warning display screen 711 (FIG. 7) on the display input unit 108 of the ATM 101, and temporarily stops the transaction.

  In this embodiment, the monitoring camera 103 is controlled by determining the start / end of the transaction based on the card insertion / discharge detection by the user. Therefore, when a suspicious object is attached without performing a transaction operation at the ATM 101, the surveillance camera 103 continues to shoot. With this image, it is possible to immediately find a suspicious object and give a warning / warning, and the effect of preventing crime can be improved.

  Further, even if a suspicious object is attached while inserting a card into the ATM 101 and performing a transaction operation, the attachment of the suspicious object can be detected at an early stage by detecting the card discharge and detecting the suspicious object after the transaction ends.

  In the above embodiment, the monitoring camera 103 is controlled and the command / alarm is transmitted to the ATM control unit 105 and the center side by the monitoring device 104. However, by adding the function of the monitoring device 104 to the ATM 101, it is the same. The effect of can be obtained.

  The imaging range of the monitoring camera 103 is for the front panel as shown in FIG. An account number or PIN number from a person who impersonates the ATM 101 with a card reader or wireless camera for voyeurism so that it is not conspicuous and alerts the user with a written poster that appears to be fraudulent. The surveillance camera 103 mainly shoots this place because the suspicious object detection photographing range 801 in FIG.

  If the shooting range of the monitoring camera 103 is fixed to the shooting range 801 for suspicious object detection and can be controlled in conjunction with other monitoring cameras attached to the ceiling or wall of a financial institution, The detection accuracy of suspicious objects can be improved.

  As described above, the embodiment of the monitoring camera 103 and the monitoring device 104 built in the ATM 101 has been described in detail with reference to the drawings. However, the present invention is not limited to the external mounting as the monitoring device 104, but is built in the ATM 101. The same effect can be obtained by adding. Further, the present invention is not limited to the monitored ATM 101, and the same effect can be obtained for devices such as vending machines such as ticket machines and automatic contract machines that can be remotely operated from the center.
