Description

  The present invention relates to an information management system, a management apparatus, and a management program. In particular, the present invention relates to a technique for performing monitoring for personal property-secured loan (ABL) using a monitoring camera.

  2. Description of the Related Art Conventionally, an apparatus that digitally processes an image signal of a monitor camera and determines a product inventory for each storage address that is fractionated in a warehouse is known (for example, see Patent Document 1).

  COCO-DATES (registered trademark) is provided as a service for authenticating the photographing time and photographing position of a photograph (see, for example, Non-Patent Document 1). This service combines the weather image (cloud shape) at the time you want to authenticate with the positioning information (latitude / longitude) from the GPS (Global Positioning System) satellite at the location you want to authenticate, and encodes it with a hash function. An authentication code for authenticating the time and position is issued.

  In movable property / credit-backed loans (ABL), even for small and medium-sized enterprises that do not have secured real estate, It is possible to receive a financing with assets as collateral. Since the contents of movable assets and receivables fluctuate from day to day, the financial institution of the loan source must frequently monitor the contents of the collateral assets, but the person in charge does not visit the site directly for monitoring. It takes a lot of work. Therefore, as a system for improving the efficiency of monitoring, a personal property / credit-backed loan monitoring system using COCO-DATES (registered trademark) has been developed (for example, see Non-Patent Document 2).

  In the movable property / credit-backed loan monitoring system, for example, the debtor takes a picture of the collateral assets with a mobile phone. At this time, the debtor obtains an authentication code for authenticating the photographing time and photographing position of the photograph using COCO-DATES (registered trademark) with the mobile phone. Then, the photograph with the authentication code added is transmitted to the person in charge at the financial institution. When the person in charge receives the photo, COCO-DATES (registered trademark) is used to check the shooting time and the shooting position of the photo, and check whether the photo was taken illegally. Then, by looking at the photos and judging the current status of collateral assets, it is possible to monitor without having to go to the field survey.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration of an information management system 100 according to the present embodiment.

  In FIG. 1, the information management system 100 includes a management device 200, an authentication device 300, and a user terminal 400.

  The management device 200, the authentication device 300, and the user terminal 400 communicate with each other via a network 101 such as the Internet. A plurality of management devices 200, authentication devices 300, and user terminals 400 may exist.

  The management device 200 is a server computer, for example, and is connected to the monitoring camera 102 via a LAN (Local Area Network) or the like. The monitoring camera 102 is, for example, installed inside a certain warehouse and constantly photographs items such as boxed frozen shrimp stored in a specific section (an example of a predetermined area) in the warehouse. A plurality of surveillance cameras 102 may be installed. The management apparatus 200 acquires and accumulates videos that are constantly or periodically captured by the monitoring camera 102 from the monitoring camera 102 via a LAN or the like. Whenever the video is acquired, the management device 200 performs image processing on the video that has already been accumulated and the video that has been newly acquired (for example, extracts and analyzes the difference between the video acquired last time and the video acquired this time). ), And calculate the amount of change in the inventory of the item and record it as event information in time series. As a result, the inventory status of the item can be grasped. When a plurality of monitoring cameras 102 are installed, the management apparatus 200 performs the same operation for each monitoring camera 102, calculates the amount of change in inventory of items photographed by each monitoring camera 102, and performs time series. Record as event information.

  The authentication device 300 is a server computer, for example, and includes a database 301. The database 301 may be installed outside the authentication apparatus 300. In this case, the authentication apparatus 300 is connected to the database 301 by a LAN, VPN (Virtual / Private / Network), or the like. For example, the authentication device 300 issues an authentication code for authenticating the current time to the management device 200 in response to a request from the management device 200. Then, the authentication device 300 causes the management device 200 to transmit data corresponding to the issued authentication code. The authentication device 300 receives the data from the management device 200 via the network 101 and stores the data in the database 301 in association with the authentication code. Thereby, the time when the data existed can be authenticated.

  In the present embodiment, the management device 200 authenticates from the authentication device 300 when the change amount is not 0 when the change amount of the inventory of the item is calculated, that is, when a change in the inventory amount of the item is detected. Get the code. Specifically, first, the management apparatus 200 requests the authentication apparatus 300 to issue an authentication code via the network 101. Upon receiving a request from the management device 200, the authentication device 300 combines the authentication time information indicating the current time with the unique specific information that can be obtained only at the current time, and generates combined data. As the authentication time information, for example, current time data obtained from a built-in clock or national standard time data obtained from a time server of NICT (Information Communication Research Organization) can be used. As the specific information, for example, data of a weather satellite image (cloud image) at the current time obtained from a server of the Japan Meteorological Agency or the Japan Weather Association can be used. The authentication device 300 calculates a hash value of the combined data obtained by combining such data, and transmits the calculated hash value as an authentication code to the management device 200 via the network 101. At this time, the authentication apparatus 300 stores the authentication time information and the specific information in a storage medium such as a memory in association with the authentication code. When the management device 200 receives the authentication code transmitted from the authentication device 300, the management device 200 displays the video (still image) acquired from the monitoring camera 102 within a predetermined time limit (for example, 1 minute) from the reception time point. The authentication code received from the authentication device 300 is transmitted to the authentication device 300 via the network 101. Upon receiving the video and the authentication code transmitted from the management device 200, the authentication device 300 reads the authentication time information corresponding to the received authentication code from the storage medium, and the time indicated by the read authentication time information and the video from the management device 200. Calculate the difference from the time of receipt. When the calculated difference is equal to or less than the time limit, the authentication device 300 determines that the video received from the management device 200 is a regular video, and uses this video and the authentication time information read from the storage medium as the management device 200. And stored in the database 301 in association with the authentication code received from. Thus, the video shooting time can be authenticated by the authentication code.

  Note that the video transmitted from the management apparatus 200 to the authentication apparatus 300 may be a video (video acquired immediately before from the monitoring camera 102) in which the management apparatus 200 detects a change in the inventory amount of the item, or the management apparatus 200. May be an image acquired from the monitoring camera 102 after detecting a change in the inventory amount of the item, but after the management device 200 detects a change in the inventory amount of the item, it further receives an authentication code from the authentication device 300 After that, it is desirable to limit to the video acquired from the monitoring camera 102. That is, it is desirable that the management apparatus 200 can transmit only the video imaged by the monitoring camera 102 and acquired from the monitoring camera 102 after receiving the authentication code from the authentication apparatus 300 to the authentication apparatus 300. By providing such a restriction, it is possible to improve the proof of the video shooting time using the authentication code. Further, the management apparatus 200 can transmit only the video captured by the monitoring camera 102 and acquired from the monitoring camera 102 until the time limit elapses after the authentication code is received from the authentication apparatus 300. May be. By doing so, it is possible to further improve the proof of the video shooting time using the authentication code.

  The management device 200 displays event information indicating that there is a change in the inventory amount of the item (change amount), a video shot by the monitoring camera 102 at the time of the change, a shooting time of the video, and a shooting time thereof. An authentication code or the like to be authenticated is associated and recorded. Then, the management apparatus 200 creates a graph visualizing the transition of the inventory amount of the item based on the recorded event information. Further, the management apparatus 200 periodically creates a report including recorded event information, a graph created from the event information, a video corresponding to the event information, a shooting time, an authentication code, and the like.

  The user terminal 400 is, for example, a PC (personal computer) or a mobile communication terminal. The user terminal 400 receives a graph created by the management apparatus 200 or a report periodically created by the management apparatus 200 from the management apparatus 200 via the network 101. Then, the user terminal 400 displays or prints the received graph or report on the screen. Thereby, the user can confirm the stock status of the goods, the transition of the stock quantity, and the like.

  In the present embodiment, the user terminal 400 makes an inquiry to the authentication device 300 via the network 101 using the authentication code included in the report received from the management device 200, and the video and authentication time information corresponding to the authentication code. To get. Specifically, when the user terminal 400 receives a report from the management apparatus 200, the user terminal 400 reads a video, a shooting time, an authentication code, and the like included in the received report. Then, the user terminal 400 transmits the read authentication code to the authentication device 300 via the network 101. The authentication device 300 receives the authentication code transmitted from the user terminal 400 and extracts the video and authentication time information corresponding to the received authentication code from the database 301. Then, the authentication apparatus 300 returns the extracted video and authentication time information to the user terminal 400 via the network 101. The user terminal 400 receives the video and authentication time information returned from the authentication device 300 and displays them on the screen. Thus, the user can check whether the video included in the report has been falsified and whether the shooting time included in the report is correct.

  The information management system 100 can be used for, for example, movable property / secured loan (ABL). Conventionally, in monitoring for ABL, the person in charge of a financial institution regularly checks the contents of collateral assets, but the frequency of monitoring is not sufficient because the contents of movable assets and receivables fluctuate from day to day. On the other hand, in the information management system 100, the collective property secured by ABL is always photographed by the monitoring camera 102, so that the inventory status of the collective property can be monitored for 24 hours 365 days. Conventionally, since humans have determined how much the contents of movable property and claims have changed, it has been qualitative. In contrast, in the information management system 100, quantitative information can be obtained by calculating the amount of change in the inventory of collective movables and recording it in time series. Conventionally, a monitoring report for ABL has been created by handwriting, but the information management system 100 can automatically create a report.

  As a modified example of the present embodiment, the surveillance camera 102 is installed inside a certain store, and always photographs items such as watches placed on display shelves (an example of a predetermined area) in the store. May be. Also in this example, the management apparatus 200 performs image processing on the video acquired from the monitoring camera 102, calculates the amount of change such as the number of items, and records it in time series.

  As a modification of the present embodiment, the surveillance camera 102 is installed for each product manufacturing / processing line (an example of a predetermined area) in a certain factory, and each surveillance camera 102 is handled by each line. (For example, raw materials, work-in-progress products, semi-finished products, and finished products) may be constantly photographed. Also in this example, the management apparatus 200 performs image processing on the video acquired from each monitoring camera 102, calculates the amount of change such as the number of items handled in each line, and records them in time series.

  As a modification of the present embodiment, when the authentication apparatus 300 receives the video and the authentication code transmitted from the management apparatus 200, the authentication apparatus 300 supports not only the authentication time information corresponding to the received authentication code but also the same authentication code. The specific information to be read may also be read from the storage medium. In this example, when the difference between the time indicated by the read authentication time information and the time when the video is received from the management device 200 is equal to or less than the time limit, the authentication device 300 uses the video received from the management device 200 and the storage medium. Not only the read authentication time information but also the specific information read from the storage medium is stored in the database 301 in association with the authentication code received from the management apparatus 200. Upon receiving the authentication code transmitted from the user terminal 400, the authentication device 300 extracts the video corresponding to the received authentication code, the authentication time information, and the specific information from the database 301. Then, the authentication device 300 returns the extracted video, authentication time information, and specific information to the user terminal 400 via the network 101. The user terminal 400 receives the video, the authentication time information, and the specific information returned from the authentication device 300 and displays them on the screen. As a result, the user can more reliably verify whether the photographing time included in the report is correct.

  Further, as a modification of the present embodiment, the management apparatus 200 accumulates the accounts receivable information of the ABL loan destination (SME) and transmits the accounts receivable information to the user terminal 400. Good. In this example, the user terminal 400 receives, from the management apparatus 200 via the network 101, the trade receivable information stored in the management apparatus 200 together with the graph and report created by the management apparatus 200. Then, the user terminal 400 displays or prints the trade receivable information together with the received graph and report on the screen. Thus, the user (person in charge of the financial institution or the like of the loan source) can grasp the actual operation status at the loan destination by comparing the receivable information and the amount of change in the inventory of the goods.

  FIG. 4 is a flowchart showing the operation of the management apparatus 200 (management method according to the present embodiment, management program processing procedure according to the present embodiment).

  In FIG. 4, the processing of steps S101 to S104 is repeatedly executed periodically (for example, every 5 minutes, every 30 minutes, every hour, or every day). For example, if it is executed every 5 minutes, the “current” process or the like is performed after 5 minutes from the “previous” process or the like.

  In step S101 (imaging processing), the imaging unit 201 acquires a video of a specific section in the warehouse captured by the monitoring camera 102 from the monitoring camera 102 via a LAN or the like and stores it in the storage device 252 as time series data. accumulate.

  As described above, in step S101, the imaging unit 201 captures a predetermined area (such as a specific section in the warehouse) in time series and generates an image (video).

  In step S <b> 102 (part of the authentication code acquisition process), the authentication code acquisition unit 202 accumulates the video acquired this time from the monitoring camera 102 by the imaging unit 201 (the video captured this time by the monitoring camera 102) and the storage device 252. A difference from the video previously acquired by the imaging unit 201 from the monitoring camera 102 (video previously captured by the monitoring camera 102) included in the time-series data is extracted by image processing. The authentication code acquisition unit 202 analyzes the extracted difference by the processing device 251 and calculates the amount of change in the inventory of the item placed in the section. The authentication code acquisition unit 202 determines whether or not the calculated change amount is 0 by the processing device 251.

  As described above, in step S102, the authentication code acquisition unit 202 analyzes the change in the image generated by the imaging unit 201, and identifies the predetermined area (a specific section in the warehouse) based on the analysis result. Whether or not this event has occurred is determined by the processing device 251. Specifically, the authentication code acquisition unit 202 determines, using the processing device 251, whether or not there is a change in the inventory amount of items placed in a predetermined area as a specific event. In addition to this, the authentication code acquisition unit 202 determines whether the number of people in a predetermined area has changed, whether the temperature has changed in the predetermined area, and the like as specific events. Also good.

  When the change amount calculated by the authentication code acquisition unit 202 in step S102 is 0 (when it is determined that there is no change in the stock amount), the process returns to step S101. On the other hand, when the change amount calculated by the authentication code acquisition unit 202 in step S102 is not 0 (when it is determined that there is a change in the inventory amount), the process proceeds to step S103.

  In step S <b> 103 (part of the authentication code acquisition process), the authentication code acquisition unit 202 transmits request data for requesting issuance of an authentication code to the authentication device 300 via the network 101. The authentication device 300 receives the request data transmitted by the authentication code acquisition unit 202 via the network 101. In response to the received request data, the authentication device 300 generates authentication data by combining authentication time information indicating the current time with unique specific information that can be obtained only at the current time. The authentication device 300 calculates a hash value of the generated composite data, transmits the calculated hash value as an authentication code to the management device 200 via the network 101, and corresponds authentication time information and specific information to the authentication code.

The authentication code acquisition unit 202 receives the video (still image) acquired by the imaging unit 201 in step S101 from the authentication device 300 within a predetermined time limit (for example, 1 minute) from the time when the authentication code is received. The authentication code is transmitted to the authentication device 300 via the network 101 together with the authentication code. Alternatively, the authentication code acquisition unit 202 executes the same processing as in step S <b> 101, and authenticates the video (still image) newly acquired by the imaging unit 201 via the network 101 together with the authentication code received from the authentication device 300. To device 300. As described above, the video newly acquired by the imaging unit 201 is preferably a video taken by the monitoring camera 102 after the authentication code acquisition unit 202 receives the authentication code from the authentication device 300, and further, the authentication code It is more desirable that the video is captured by the monitoring camera 102 from the time when the acquisition unit 202 receives the authentication code from the authentication device 300 until the time limit elapses. The authentication device 300 receives the video and the authentication code transmitted from the authentication code acquisition unit 202 via the network 101. The authentication device 300 reads the authentication time information (and specific information) corresponding to the received authentication code from the storage medium, and the time indicated by the read authentication time information and the time when the video transmitted by the authentication code acquisition unit 202 is received.
