  In addition, a large number of various types of products 6 are exhibited in the store 1, and RFIDs (symbol 7 in FIG. 2) are attached to these products 6 so that they are not easily removed. ing.

  Further, an RFID antenna 8 for managing inventory of the product 6 is arranged in the store 1 by communication with the RFID (symbol 7 in FIG. 2).

  Further, a POS register 10 is installed in the checkout office 9 in the store 1, and a sales management camera 11 is also arranged in the checkout office 9. Sales data from the POS register 10 is recorded in the POS server 17 and managed by the POS inventory management unit 18 of the product 6.

  Furthermore, in the store 1, a plurality of surveillance cameras 12 are arranged at various places. The in-store camera 3, the in-store camera 5, the RFID antenna 8, the POS server 17, the sales management camera 11, and the monitoring camera 12 are connected to the control unit 13.

  The control unit 13 includes a face information recording unit 14 for recording customer face information captured by the store entrance camera 3, the store exit camera 5, the sales management camera 11, and the surveillance camera 12, an RFID antenna 8, and an RFID antenna. RFID inventory management unit 15 that records the inventory information of the product 6 obtained by 8, the POS server 17 in which the inventory information obtained by the POS register 10 is recorded in the POS inventory management unit 18, and the video transmitted from each camera And a display unit 16 for displaying data such as inventory information.

  The normal operation in the store 1 is based on the control by the control unit 13, and the store camera 3 captures the face information of the store clerk and records it in the face information recording unit 14 (S31 in FIG. 3). 5, the face information of the store clerk is photographed and recorded in the face information recording unit 14 (S41 in FIG. 4).

  Further, the control unit 13 periodically activates the RFID antenna 8 by the time management unit 19 (for example, once an hour), and performs inventory management of the product 6 existing in the store 1 (S51 in FIG. 5).

  At the time of inventory management, the activation of the RFID antenna 8 is repeated a plurality of times within a few minutes, whereby the product 6 existing in the store 1 is acquired from information from the RFID 7 attached thereto (FIG. 5). S52), the acquired information (ID) is recorded in the RFID inventory management unit 15 (S53 in FIG. 5).

  Thereafter, the presence / absence of shoplifting is confirmed from the product 6 present in the store 1 confirmed by the RFID inventory management unit 15 and the product 6 confirmed to be sold by the POS server 17 (S54 in FIG. 5).

  In other words, the presence / absence of shoplifting is confirmed by confirming the presence / absence of the product 6 that has been sold (stolen) even though it has not been sold.

  For example, when the RFID antenna 8 is activated, there are 10 specific products, and when one sale is confirmed in the POS register 10 by the time the RFID antenna 8 is activated this time, 9 items 6 should exist, but if only 8 items exist, the control unit 13 determines that one item was shoplifted (S55 in FIG. 5).

  When the control unit 13 determines that shoplifting (mismatch) exists, the face information recording unit 14 stores the face information of the store clerk taken by the store closing camera 5 between the previous activation of the RFID antenna 8 and the current activation. to manage. That is, the person who has left the store during this period is identified as a suspicious person. When it is determined that there is no shoplifting (non-coincidence), it waits until the next timer activation time.

  Then, the control unit 13 repeats steps S51 to S55 of FIG. 5, and identifies and records a store clerk managed multiple times in the face information recording unit 14 as a suspicious person when it is determined that shoplifting (mismatch) exists. can do. The face (representative) image recorded as the suspicious person in the face information recording unit 14 is compared with the video from the entrance camera, as will be described later, and alerts the store clerk when the suspicious person revisits the store. It is used for that.

  In addition, it is possible to detect that the suspicious person extracted (listed up) many times is likely to be a shoplifting addict and to increase the accuracy of the suspicious person. It is expected that the strength of the system will be publicized and shoplifting will be drastically reduced.

  In order to execute such an operation, the control unit 13 performs the control shown in FIG. 3 based on information from the in-store camera 3.

  In other words, the store entrance camera 3 always captures the face information of the store entrance person and records the face information in the face information recording unit 14 (S31 in FIG. 3).

  Next, the control unit 13 compares the shoplifter candidate managed by the face information recording unit 14 with the face information of the newly entered shopkeeper (S32 in FIG. 3).

  If the shoplifter candidate managed by the face information recording unit 14 matches the face information of the newly entered store by this comparison (S33 in FIG. 3), the control unit 13 immediately detects the RFID antenna. 8 is started and current inventory management is executed (S34 in FIG. 3).

  In addition, the control unit 13 displays an alarm on the display unit 16 (S35 in FIG. 3), and causes the monitoring camera 12 disposed in the store 1 to perform a tracking operation.

  On the other hand, the control unit 13 performs the control shown in FIG. 4 based on the information from the store closing camera 5.

  That is, as described above, the control unit 13 always captures the face information of the store clerk by the store closing camera 5 and records it in the face information recording unit 14 (S41 in FIG. 4).

  Next, the control unit 13 compares the shoplifter candidate managed by the face information recording unit 14 with the face information of the person leaving the store (S42 in FIG. 4).

  If the shoplifter candidate managed by the face information recording unit 14 matches the face information of the person leaving the store by this comparison (S43 in FIG. 4), the control unit 13 immediately turns the RFID antenna 8 on. Start up and perform current inventory management.

  If there is a stock mismatch, the control unit 13 displays a warning on the display unit 16 (S44 to S47 in FIG. 4).

  Since the sales management camera 11 placed at the location of the POS register 10 can easily capture the face information of the store visitor in the POS register 10, the liquidation is completed in the POS register 10 from the shoplifter candidates described above. By removing visitors, it helps to improve the accuracy of shoplifter candidates.

  As described above, in the present embodiment, the RFID antenna 8 disposed in the store 1 is periodically activated to perform inventory management of products existing in the store 1 and to exit when shoplifting occurs. Since the shoplifter is trying to identify shoplifters, it is not necessary to install the RFID antenna 8 for each product, so that the equipment cost can be reduced. However, it is possible to provide a security system that can be easily adopted.

  Note that the face authentication technology of the control unit 13 using the store entrance camera 3, the store exit camera 5, the sales management camera 11, and the surveillance camera 12 in the present embodiment is also described in the above-described prior document 1. However, since it is a well-known technology, it is not described in order to avoid complicating the explanation. However, many documents have been introduced, and there are commercialized products. For example, those skilled in the art can easily put the present invention into practical use.

  As described above, in the present invention, by periodically starting the RFID antenna arranged in the store, the inventory management of the products existing in the store is performed, and the shoplifter is charged with the shoplifter when the shoplifting occurs. Since it is intended to identify, it is not necessary to install an RFID antenna for each product, so the equipment cost can be reduced, and as a result, it can be easily adopted even in stores with a large number of products sold or sold. A shoplifting detection device can be provided.

  Therefore, installation in various stores is expected.
