Specific embodiments will be described in more detail below with reference to the drawings.

[First embodiment]
The first embodiment will be described in more detail using the drawings.

The dangerous goods management system according to the first embodiment is a system that manages the owners of dangerous goods. For example, the dangerous goods management system according to the first embodiment manages dangerous goods such as guns, bullets (ammunition), swords, and powerful drugs that cannot be purchased without the purchaser presenting an identification card.

In the first embodiment, the configuration, operation, etc. of a dangerous goods management system will be explained using guns and bullets as examples of dangerous goods. However, it goes without saying that the objects to be managed by the dangerous goods management system according to the present disclosure are not limited to guns or bullets.

[System configuration]
As shown in FIG. 3, the dangerous goods management system (information processing system) according to the first embodiment includes a management center, a plurality of businesses, and an investigation agency.

The management center manages the manufacturers, distribution routes, etc. of dangerous goods (guns, bullets). The management center is operated by a national administrative agency or a private company commissioned by the government. The management center screens applicants for purchasing dangerous goods and manages information on people who have purchased dangerous goods. The management center also cooperates in criminal investigations in response to requests from investigative agencies (police, prosecutors, etc.).

The management center includes a server device 10. The server device 10 is a server that handles the main operations of the management center. The server device 10 may be installed in a building of a management center, or may be installed on a network (on a cloud).

Examples of businesses operating hazardous materials management systems include manufacturers of hazardous materials (gun manufacturers, bullet manufacturers), distribution businesses that distribute hazardous materials, and distributors that sell hazardous materials.

As mentioned above, the investigating agency is a public agency such as the police or prosecutor's office.

Although not shown in FIG. 3, hazardous materials management system operators and investigative agencies have information processing devices such as servers and terminals. Each device included in the hazardous materials management system is interconnected. Specifically, the server device 10 and the operator's terminal etc. are connected by wired or wireless communication means and are configured to be able to communicate with each other.

The configuration of the hazardous materials management system shown in FIG. 3 is an example, and is not intended to limit the configuration. For example, a dangerous goods management system may include a plurality of server devices 10.

[Overview of operation]
Next, the general operation of the hazardous materials management system according to the first embodiment will be described.

<Gun manufacturing>
At a gun manufacturer's manufacturing plant, "object fingerprints" are taken from guns that have undergone product quality checks. Note that since the object fingerprint is acquired without contacting the product, it does not affect the quality of the product (gun).

Object fingerprints are patterns (graphic patterns, pattern patterns) that are unique to each product (object). More specifically, the object fingerprint is not the design of the product, but the uneven color, unevenness, minute scratches, etc. that are unique to each individual product. Since the object fingerprint is unique information for each product, object fingerprints obtained from the same product match (substantially match). That is, the object fingerprint functions as an ID that can uniquely identify the manufactured gun.

As shown in FIG. 4, the gun manufacturer's production line includes a gun manufacturing management terminal 20 and a camera-equipped microscope 21. The camera-equipped microscope 21 and the gun manufacturing management terminal 20 are connected by wired or wireless communication means.

Object fingerprints are obtained by photographing an enlarged object under appropriate lighting conditions. Specifically, a worker on the gun manufacturing line operates the camera-equipped microscope 21 via the gun manufacturing management terminal 20 . The camera-equipped microscope 21 photographs a predetermined area of the gun (the black area in FIG. 4) and transmits the image data to the gun manufacturing management terminal 20.

The gun manufacturing management terminal 20 acquires (generates and extracts) an object fingerprint from the acquired image data. For example, the gun manufacturing management terminal 20 generates an object fingerprint by applying a predetermined filter, correction, etc. to image data. Note that since existing technology can be used to obtain the object fingerprint, a more detailed explanation will be omitted.

As mentioned above, since an object fingerprint functions as an ID that allows a product to be uniquely identified, it is desirable that it remains unchanged for a long period of time (ideally, forever). Therefore, it is desirable for gun manufacturers to obtain the object fingerprint from a location where the object fingerprint does not change easily. For example, it is preferable that the object fingerprint be obtained from the bottom of the grip or from a plate attached to the gun.

When the object fingerprint is taken, the operator inputs the serial number of the gun from which the object fingerprint was taken into the gun manufacturing control terminal 20. For example, an operator reads a serial number stamped on a gun and inputs the read serial number into the gun manufacturing control terminal 20. Alternatively, the operator operates a camera (not shown in FIG. 4) via the gun manufacturing control terminal 20 to photograph the serial number. The gun manufacturing control terminal 20 may acquire the serial number by analyzing image data showing the serial number.

When the serial number is input, the gun manufacturing management terminal 20 sends a manufactured gun information notification including the manufactured gun's object fingerprint (hereinafter referred to as gun object fingerprint), serial number, and business ID (manufacturer ID). is transmitted to the server device 10.

The business ID is an ID for identifying a business included in the hazardous materials management system. Any identification information can be used as the business ID. The business ID is shared between the management center and each business by any method. For example, a system administrator determines a business ID and notifies each business operator of the determined business ID.

The server device 10 associates the company ID, serial number, and gun object fingerprint included in the manufactured gun information notification and stores them in the gun management database. Details of the gun management database will be described later.

<Manufacture of bullets>
At a bullet manufacturer's manufacturing plant, "object fingerprints" are taken from bullets that have undergone product quality checks.

As shown in FIG. 5, the bullet manufacturer's production line includes a bullet production management terminal 30 and a camera-equipped microscope 31. The camera-equipped microscope 31 and the bullet production management terminal 30 are connected by wired or wireless communication means.

The operator operates the camera-equipped microscope 31 via the bullet manufacturing management terminal 30 to obtain image data for generating object fingerprints. Alternatively, the camera-equipped microscope 31 automatically photographs a bullet carried by a belt conveyor or the like, and transmits image data for generating the object fingerprint to the bullet manufacturing management terminal 30.

The bullet manufacturing management terminal 30 generates and stores a bullet object fingerprint (hereinafter referred to as a bullet object fingerprint) from the acquired image data.

The bullets whose object fingerprints have been taken are stored in the bullet case in the order in which the object fingerprints were taken. When a predetermined number of bullets are stored in the bullet case (when the bullet case is full of bullets), the operator inputs the "case ID" given to the bullet case into the bullet manufacturing management terminal 30.

For example, the operator reads the case ID attached to the bullet case and inputs the read case ID into the bullet manufacturing management terminal 30. Alternatively, if the case ID has been converted into a barcode, two-dimensional barcode, etc., the operator inputs the case ID into the bullet manufacturing management terminal 30 using a barcode reader (not shown in FIG. 5). do.

Upon acquiring the case ID, the bullet manufacturing management terminal 30 sends a "manufactured bullet information notification" that includes the bullet manufacturer's business ID, the case ID, and at least one bullet object fingerprint stored in the bullet case corresponding to the case ID. ” to the server device 10. For example, when 100 bullets are stored in one bullet case, a manufacturing bullet information notification including one case ID and 100 bullet object fingerprints is transmitted to the server device 10.

The server device 10 associates the business ID, case ID, and at least one bullet object fingerprint included in the manufactured bullet information notification and stores them in the bullet management database. Details of the bullet management database will be described later.

<Distribution of dangerous goods>
Distribution businesses that handle dangerous goods (guns, bullets) are required to report the distribution route of the dangerous goods to the control center. When purchasing dangerous goods (guns, bullets), the distribution business enters information identifying the dangerous goods (see FIGS. 6 and 7).

For example, as shown in FIG. 6, when a distribution company purchases a gun, an operator inputs the serial number of the gun into the distribution company terminal 40. As shown in FIG. 7, when a distribution company purchases bullets, an operator inputs the case ID of the bullet case into the distribution company terminal 40.

Furthermore, when purchasing hazardous materials, the distribution business enters into the distribution business terminal 40 information that identifies the supplier and sales destination of the dangerous materials (for example, the business IDs of the supplier and sales destination).

The distribution business terminal 40 stores information such as the business ID of the company (distribution business), the business IDs of suppliers and sales destinations, and information identifying the hazardous materials handled (hazardous material identification information; for example, gun serial numbers, bullets, etc.). A "dangerous goods distribution notification" including the case ID) is sent to the server device 10.

The server device 10 searches the corresponding database using the dangerous goods identification information (gun serial number or bullet case case ID) included in the dangerous goods distribution notification as a key, and identifies the dangerous goods (guns, bullets) to be distributed. do. The server device 10 stores the distribution route (business IDs of the supplier, distribution business, and sales destination) in the entry of the specified dangerous goods.

<Sales of dangerous goods>
A sales business that sells dangerous goods to end consumers needs to obtain permission from the management center to sell dangerous goods to those who wish to purchase them (see FIGS. 8 and 9).

Specifically, a store clerk at a sales business temporarily takes identification documents (for example, a driver's license with a facial image attached) from a person who wishes to purchase dangerous goods. The store clerk operates the seller terminal 50 to take a photograph of the identification document received from the prospective purchaser.

Additionally, the store clerk or the like operates the seller terminal 50 to obtain biometric information of the person who wishes to purchase the dangerous goods.

Note that examples of biometric information include data (feature amounts) calculated from physical characteristics unique to an individual, such as a face, a fingerprint, a voice print, a vein, a retina, and a pattern of the iris of the eye. Alternatively, the biometric information may be image data such as a face image or a fingerprint image. The biometric information may be anything that includes the user's physical characteristics as information. In the embodiment disclosed herein, a case will be described in which biometric information regarding a person's "face" (a face image or a feature amount generated from a face image) is used.

For example, the seller terminal 50 controls a camera to take a picture of the person who wishes to purchase, and obtains a facial image.

After acquiring the identity verification documents and biometric information, the seller terminal 50 collects the dangerous goods identification information that identifies the dangerous goods, the identity verification documents (image data showing the identity verification documents), the biometric information (facial image), and the seller's information. A “sales availability determination request” including the business ID is transmitted to the server device 10. Note that, as described above, the dangerous substance identification information is, for example, the serial number of a gun or the case ID of a bullet case. As shown in FIG. 8, a sales business that sells guns inputs the serial number of the gun into the seller terminal 50. As shown in FIG. 9, a sales business that sells bullets inputs the case ID of the bullet case into the seller terminal 50.

Upon receiving the sales permission determination request, the server device 10 determines whether the dangerous goods can be sold to the person who wishes to purchase the dangerous goods. Specifically, the server device 10 determines that the dangerous goods can be sold if the identity of the purchaser is successfully verified and the purchaser is not a criminal or the like. Note that the server device 10 determines that identity verification has been successful when the photographed facial image obtained by photographing the person wishing to purchase dangerous goods and the facial image obtained from the identity verification document are of the same person. do.

If it is determined that the dangerous goods can be sold, the server device 10 acquires information that identifies the owner of the dangerous goods (owner identification information). For example, the server device 10 reads owner identification information from an identification document presented at a seller by a person who wishes to purchase a dangerous object (an owner of a dangerous object).

For example, the server device 10 reads the name and address of the dangerous goods owner from the identification document as the owner identification information. Alternatively, the server device 10 reads the ID (ID issued by a public institution) from the identity verification document as the owner identification information. For example, the server device 10 reads out a driver's license number, social security number, national insurance number, etc. as owner identification information.

The server device 10 stores the acquired owner identification information in the database. Specifically, the server device 10 stores the gun purchaser's owner identification information in the gun management database. Alternatively, the server device 10 stores the owner identification information of the bullet purchaser in the bullet management database.

The server device 10 transmits the determination result (dangerous goods can be sold or cannot be sold) to the seller terminal 50. When notified by the management center that ``dangerous goods can be sold,'' the salesperson sells the dangerous goods. When notified by the management center that the sale of dangerous goods is not allowed, the store clerk at the retailer refuses to sell the dangerous goods. For example, if identity verification fails or if the person wishing to purchase dangerous goods is listed on a blacklist, which will be described later, the sale of dangerous goods will be refused.

<Cooperation with investigative agencies>
The management center will cooperate with criminal investigations by investigative agencies. Items left at a crime scene (eg, a gun and/or bullets) are brought to an investigative agency. As shown in FIGS. 10 and 11, the investigation agency includes an investigation agency terminal 60 and a camera-equipped microscope 61. The camera-equipped microscope 61 and the investigation agency terminal 60 are connected by wired or wireless communication means.

An investigator or the like of an investigative agency operates the investigative agency terminal 60 to request the management center (server device 10) to provide information regarding the belongings left behind.

Specifically, an investigator or the like operates a camera-equipped microscope 61 via an investigation agency terminal 60 to obtain image data for generating an object fingerprint. The investigation agency terminal 60 generates an object fingerprint of the belongings left behind from the acquired image data. For example, as shown in FIG. 10, when a gun is recovered as a leftover item, an object fingerprint of the gun is generated. As shown in FIG. 11, when a bullet is recovered as a leftover item, an object fingerprint of the bullet is generated.

Here, the investigation agency or the like obtains information by requesting the manufacturer of the dangerous object to provide information regarding the location where the object fingerprint is obtained from the dangerous object (in the example of FIG. 4, the black area of the gun). Alternatively, an investigative agency or the like obtains the location from which the fingerprint of the object is to be obtained via the management center. Note that the location where object fingerprints are obtained from dangerous objects will not be disclosed to general consumers.

When the investigator requests the provision of information regarding the owner of the property, the investigation agency terminal 60 transmits an "owner information provision request" including the generated object fingerprint (gun object fingerprint or bullet object fingerprint) to the server device 10. do.

Upon receiving the owner information provision request, the server device 10 compares the object fingerprint included in the owner information provision request with the object fingerprint registered in the database, and identifies the dangerous object corresponding to the leftover item. For example, when the server device 10 obtains a gun object fingerprint, it uses at least one or more gun object fingerprints registered in the gun management database to identify an entry corresponding to a gun left at a crime scene. Alternatively, when the server device 10 obtains the bullet object fingerprint, it identifies an entry corresponding to the bullet left at the crime scene using at least one or more bullet object fingerprints registered in the bullet management database.

The server device 10 reads owner identification information (for example, name and address, or ID such as driver's license number) of the entry identified by the verification process from the database.

The server device 10 transmits the read owner identification information to the investigation agency terminal 60. The investigation agency terminal 60 presents the acquired owner identification information to an investigator or the like. Investigators use the information presented to them in criminal investigations.

Next, details of each device included in the hazardous materials management system according to the first embodiment will be explained.

Further, the communication control unit 201 transmits data to the gun manufacturing management terminal 20. The communication control unit 201 passes data received from other devices to other processing modules. The communication control unit 201 transmits data acquired from other processing modules to other devices. In this way, other processing modules transmit and receive data to and from other devices via the communication control unit 201. The communication control unit 201 has a function as a reception unit that receives data from another device, and a function as a transmission unit that transmits data to the other device.

The dangerous goods manufacturing management department 202 is a means for managing the manufacturing of dangerous goods (guns or bullets). The dangerous goods manufacturing management unit 202 receives dangerous goods identification information that identifies the manufactured dangerous goods and object fingerprints of the manufactured dangerous goods from the manufacturer's terminal. The dangerous goods manufacturing management unit 202 stores the received dangerous goods identification information and object fingerprint in a dangerous goods management database (gun management database, bullet management database).

The dangerous goods manufacturing management department 202 processes the "manufactured gun information notification" received from the gun manufacturing management terminal 20 or the "manufactured bullet information notification" received from the bullet manufacturing management terminal 30.

Upon receiving the manufacturing gun information notification, the dangerous goods manufacturing management department 202 adds a new entry to the gun management database (see FIG. 13). The dangerous goods manufacturing management unit 202 registers the business ID (manufacturer ID), gun serial number, and gun object fingerprint included in the received manufactured gun information notification in the newly added entry.

Note that the gun management database shown in FIG. 13 is an example, and is not intended to limit the items to be stored. For example, the date and time when the manufacturing gun information notification was processed may be registered in the gun management database.

The dangerous goods manufacturing management department 202 processes the manufactured bullet information notification in the same manner as the manufactured gun information notification. Specifically, the dangerous goods manufacturing management department 202 registers the information included in the manufactured bullet information notification in the bullet management database (see FIG. 14).

As shown in FIG. 14, the bullet object fingerprint field of the bullet management database stores at least one bullet object fingerprint of a bullet.

The dangerous goods distribution management unit 203 is a means for managing the distribution of dangerous goods (guns or bullets). The dangerous goods distribution management unit 203 receives the dangerous goods identification information of the dangerous goods to be distributed and the distribution route of the dangerous goods to be distributed from the terminal of the distribution business operator. The dangerous goods distribution management unit 203 stores the distribution route of the dangerous goods to be distributed in the entry specified by searching the dangerous goods management database using the dangerous goods identification information of the dangerous goods to be distributed.

The dangerous goods distribution management department 203 processes the "dangerous goods distribution notification" received from the distribution business terminal 40. The dangerous goods distribution management unit 203 searches the database using the dangerous goods identification information (gun serial number or bullet case case ID) included in the dangerous goods distribution notification as a key, and identifies the corresponding entry.

When the serial number of the gun is included in the dangerous goods distribution notification, the dangerous goods distribution management unit 203 searches the gun management database using the gun serial number as a key and identifies the corresponding entry. When the case ID of the bullet case is included in the dangerous goods distribution notification, the dangerous goods distribution management unit 203 searches the bullet management database using the case ID as a key and identifies the corresponding entry.

The dangerous goods distribution management unit 203 stores the distribution route (business ID of each supplier, distribution business operator, and sales destination) included in the dangerous goods distribution notification in the distribution route field of the specified entry.

Note that, as shown in FIGS. 13 and 14, the business ID that is first written in the distribution route field matches the manufacturer ID of the gun or bullet. Further, among the setting values in the distribution route field, units separated by semicolons correspond to distribution routes sent from one distribution business operator. In the example of FIG. 13, the distribution route consisting of "mID01", "ID02", and "ID03" indicates that the distribution business with ID02 purchased guns from the manufacturer with mID01 and sold them to the sales destination with ID03. .

The dangerous goods sales control unit 204 is a means for controlling the sale of dangerous goods (guns or bullets).

The dangerous goods sales control unit 204 receives a sales propriety determination request including the identification document of the person who wishes to purchase the dangerous goods and the biometric information acquired from the person who wishes to purchase the dangerous goods from the terminal of the sales business. If the dangerous goods sales control unit 204 succeeds in verifying the identity using at least the biometric information written on the identification document and the biometric information obtained from the person wishing to purchase the dangerous goods, the dangerous goods sales control unit 204 determines whether the sales business wishes to purchase the dangerous goods. permit a person to sell dangerous goods.

The dangerous goods sales control unit 204 processes a "sale permission determination request" received from the seller terminal 50. FIG. 15 is a flowchart showing an example of the operation of the dangerous goods sales control unit 204 according to the first embodiment. The operation of the dangerous goods sales control unit 204 according to the first embodiment will be described with reference to FIG. 15.

Upon receiving the sales permission determination request, the dangerous goods sales control unit 204 carries out identity verification regarding the person who wishes to purchase the dangerous goods. Specifically, the dangerous goods sales control unit 204 executes a matching process using the biometric information obtained from the identification document included in the sales permission determination request and the biometric information obtained from the purchase applicant (step S101). ).

Specifically, the dangerous goods sales control unit 204 effectively uses the biometric information (facial image) written on the identification document and the biometric information (facial image) obtained by photographing the person wishing to purchase the dangerous goods. Determine whether or not there is a match and verify the identity.

The dangerous goods sales control unit 204 generates feature amounts from each of the facial image included in the sales permission determination request and the facial image written (affixed) on the identification document.

Note that existing technology can be used for feature value generation processing, so a detailed explanation thereof will be omitted. For example, the dangerous goods sales control unit 204 extracts the eyes, nose, mouth, etc. from the face image as feature points. Thereafter, the dangerous goods sales control unit 204 calculates the positions of each feature point and the distance between each feature point as feature quantities (generates a feature vector made up of a plurality of feature quantities).

Next, the dangerous goods sales control unit 204 executes a matching process (one-to-one matching) using the two generated feature amounts. Specifically, the dangerous goods sales control unit 204 calculates the degree of similarity between corresponding face images using two feature amounts. The dangerous goods sales control unit 204 determines whether the two images are face images of the same person based on the result of threshold processing for the calculated degree of similarity. Note that chi-square distance, Euclidean distance, or the like can be used for the similarity. The farther the distance, the lower the similarity, and the closer the distance, the higher the similarity.

If the degree of similarity is greater than a predetermined value (if the distance is shorter than a predetermined value), the dangerous goods sales control unit 204 determines that the identity verification has been successful. If the degree of similarity is less than or equal to a predetermined value, the dangerous goods sales control unit 204 determines that the identity verification has failed.

If the identity verification fails (step S102, No branch), the dangerous goods sales control unit 204 sets "sale not possible" in response to the sale permission determination request (step S103).

If the identity verification is successful (step S102, Yes branch), the dangerous goods sales control unit 204 determines whether the person wishing to purchase the dangerous goods is listed on a blacklist created by an investigative agency or the like (blacklist determination ; step S104). That is, the dangerous goods sales control unit 204 determines that the person who wishes to purchase the dangerous goods does not fall under the category of a person prohibited from selling dangerous goods by an investigative agency or the like.

Specifically, the dangerous goods sales control unit 204 sends a server (crime history server; not shown in FIG. 3, etc.) having the above-mentioned blacklist to a server that has the above-mentioned blacklist, and blacklists the person who wishes to purchase the dangerous goods as a person who cannot purchase the dangerous goods. Inquire whether it is on the list. Specifically, the dangerous goods sales control unit 204 transmits the facial image of the person wishing to purchase the dangerous goods to a crime history server that has a blacklist in which biometric information of criminals and the like is stored. The dangerous goods sales control unit 204 receives the determination result (listed on the blacklist, not listed on the blacklist) from the crime history server.

Incidentally, the dangerous goods sales control unit 204 may transmit information (for example, name, address, etc.) identifying the person who wishes to purchase the dangerous goods to a server having a blacklist. In other words, the determination of whether a person wishing to purchase dangerous goods is on a blacklist may be made using biometric information (a facial image or a feature amount generated from a facial image), or by using information such as a person's name. It may also be carried out using

If it is listed on the blacklist (step S105, Yes branch), the dangerous goods sales control unit 204 sets "sale not allowed" in response to the sale permission determination request (step S103).

If it is not listed on the blacklist (step S105, No branch), the dangerous goods sales control unit 204 sets "saleable" in response to the saleability determination request (step S106).

Additionally, the dangerous goods sales control unit 204 stores the business ID (seller ID) included in the sales permission/prohibition determination notification in a database (gun management database, bullet management database). Furthermore, the dangerous goods sales control unit 204 stores in the database "owner identification information" that identifies the purchaser (the owner of the dangerous goods) who is permitted to sell the dangerous goods.

For example, the dangerous goods sales control unit 204 stores the name, address, etc. of the owner of the dangerous goods (the name, address, etc. written on the identification document) in the database. Alternatively, the dangerous goods sales control unit 204 stores the ID obtained from the identification document (for example, driver's license number, social security number, national insurance number, etc.) in the database as owner identification information.

Alternatively, the dangerous goods sales control unit 204 may store the biological information (facial information; face image, feature amount) of the owner of the dangerous goods in the database. The biometric information stored in the database may be biometric information obtained from an identification document or may be biometric information obtained from a person who wishes to purchase dangerous goods.

The dangerous goods sales control unit 204 transmits a response to the sales permission determination request (determination result; sale possible, sale not possible) to the seller terminal 50 (step S107).

In this way, the dangerous goods sales control unit 204 performs identity verification when one-on-one matching using the biometric information written on the identity verification document and the biometric information obtained from the person wishing to purchase the dangerous goods is successful. Determine it as successful. Furthermore, if the dangerous goods sales control unit 204 succeeds in verifying the identity of the person who wishes to purchase the dangerous goods, and the person who wishes to purchase the dangerous goods is not listed on the blacklist as a person who cannot purchase dangerous goods, the dangerous goods sales control unit 204 will Business operators are permitted to sell hazardous materials to those who wish to purchase them.

The information provision control unit 205 matches object fingerprints (images taken of dangerous objects) using an image matching method using local feature amounts and an algorithm that verifies the consistency of the geometric arrangement of feature points. First, the information provision control unit 205 extracts, from the object fingerprint (object fingerprint image), a place where the luminance changes sharply and whose position can be stably determined as a feature point. Thereafter, the information provision control unit 205 converts the local brightness pattern around the feature point into data as a feature amount. Further, the information provision control unit 205 calculates a pair of feature points with the smallest difference in feature amount from both images to be compared. Finally, the information provision control unit 205 verifies the geometric consistency of the overall arrangement of feature points. The information provision control unit 205 extracts a pair group whose relative positional relationship with other feature points is consistent from the obtained pair group. The information provision control unit 205 calculates a matching score for both images using the total number of feature points extracted from the two images to be matched and the number of feature point pairs whose geometric arrangement is correct. The information provision control unit 205 determines that object authentication has been successful if the matching score is greater than or equal to a predetermined threshold. The information provision control unit 205 determines that object authentication has failed if the matching score is smaller than a predetermined threshold.

Note that if the object fingerprint included in the owner information provision request is a gun object fingerprint, the information provision control unit 205 executes the object authentication described above using the gun object fingerprint stored in the gun management database. Furthermore, if the object fingerprint included in the owner information provision request is a bullet object fingerprint, the information provision control unit 205 executes the object authentication using the bullet object fingerprint stored in the bullet management database.

If object authentication fails (step S202, No branch), the information provision control unit 205 notifies the investigation agency terminal 60 that the dangerous object corresponding to the object fingerprint included in the owner information provision request is not registered in the database. do. Specifically, the information provision control unit 205 transmits a negative response to the investigating agency terminal 60 (step S203).

If the object authentication is successful (step S202, Yes branch), the information provision control unit 205 acquires the owner identification information of the entry (entry in the gun management database or bullet management database) corresponding to the object fingerprint for which the object authentication was successful. (Step S204).

The information provision control unit 205 transmits an affirmative response including the acquired owner identification information to the investigating agency terminal 60 (step S205).

The storage unit 206 is a means for storing information necessary for the operation of the server device 10.

The investigative agency terminal 60 presents the notified owner identification information to an investigator of the investigative agency (step S16).

<Modification example according to the first embodiment>
In the first embodiment, it has been described that the server device 10 uses a bullet management database, which is a single database, regarding bullet management and information provision. However, the server device 10 may manage bullets and provide information using a plurality of databases.

In the dangerous goods management system according to the modification of the first embodiment, a case ID for identifying a bullet case in which a bullet is stored is registered in the server device 10. Specifically, the bullet manufacturer notifies the server device 10 of the case ID (ID converted into a two-dimensional barcode or the like) of the bullet case. Similarly, a distribution company that handles bullet cases (bullet cases containing bullets) notifies the server device 10 of the case ID of the purchased bullet case. Similarly, a vendor who sells bullets (bullet cases) notifies the server device 10 of the case ID of the bullet case to be sold to a bullet purchaser.

Note that the notification of the case ID by each business operator can be the same as the method described in the first embodiment, so detailed explanation will be omitted. For example, the bullet manufacturing management terminal 30 may transmit a manufacturing bullet information notification including the case ID of the bullet case to the server device 10. Note that the manufactured bullet notification does not include the bullet object fingerprint. The distribution business terminal 40 transmits a dangerous goods distribution notification including the case ID of the bullet case to the server device 10. Similarly, the seller terminal 50 transmits a sales permission determination request including the case ID of the bullet case.

The server device 10 constructs a bullet case management database for managing bullet cases by processing notifications and requests (manufactured bullet information notification, dangerous goods distribution notification, sales propriety determination request) received from each business operator. . Specifically, each processing module of the dangerous goods manufacturing management section 202, the dangerous goods distribution management section 203, and the dangerous goods sales control section 204 of the server device 10 performs the processing, control, etc. described in the first embodiment. conduct. As a result, a bullet case management database as shown in FIG. 21 is constructed. The bullet case management database stores case IDs of manufactured bullets in association with information specifying distribution routes and owners (bullet purchasers).

Further, in the dangerous goods management system according to the first embodiment, the object fingerprint of the bullet and the case ID of the bullet case storing the bullet are registered in the server device 10 at an arbitrary timing. For example, a bullet manufacturer that manufactures bullets takes bullet object fingerprints for each bullet housed in a bullet case. Furthermore, the bullet manufacturer obtains the case ID of the bullet case that stores the bullet from which the bullet object fingerprint was taken.

The bullet manufacturer (terminal, computer, etc. installed at the bullet manufacturer) transmits the acquired at least one object bullet fingerprint and the corresponding case ID to the server device 10.

Note that the entity that transmits the bullet object fingerprint and case ID to the server device 10 is not limited to the bullet manufacturer. Any entity included in the dangerous goods management system can send the bullet object fingerprint and case ID to the server device 10. That is, the bullet object fingerprint and the case ID need only be transmitted to the server device 10 before the bullet stored in the bullet case is sold to the bullet purchaser.

FIG. 22 is a diagram illustrating an example of a processing configuration (processing module) of the server device 10 according to a modification of the first embodiment. Referring to FIG. 22, a case ID processing unit 207 is added to the configuration of the server device 10 according to the first embodiment.

The case ID processing unit 207 is a means for processing the received bullet object fingerprint and case ID. When the case ID processing unit 207 receives the bullet object fingerprint and case ID from a bullet manufacturer or the like, it stores the received bullet object fingerprint and case ID in the bullet object fingerprint management database (see FIG. 23).

Upon receiving the owner information provision request including the bullet object fingerprint collected from the bullet in the remains, the information provision control unit 205 stores the bullet object fingerprint included in the owner information provision request and the bullet object fingerprint management database. Execute object authentication using bullet object fingerprints. When the object authentication is successful, the information provision control unit 205 searches the bullet case management database using the case ID specified by the object authentication as a key, and identifies the corresponding entry.

The information provision control unit 205 transmits the owner identification information of the identified entry to the investigation agency terminal 60.

In this way, if a traceability system for bullets (bullet casings) using the case ID of bullet casings has been established, adding a process to associate and store the object fingerprint of the bullet and the case ID will allow the bullets to remain at the crime scene. A system will be built to identify the owner of the bullet. That is, by acquiring the bullet object fingerprint and case ID at an arbitrary timing and registering them in the system, a system for identifying the owner of the bullet left at the crime scene (bullet purchaser) can be easily constructed.

As described above, in the dangerous goods management system according to the first embodiment, the object fingerprint of a dangerous object and information identifying the owner of the dangerous object are stored in the server device 10. That is, when a gun or bullet is sold, after the identity of the purchaser of the gun or bullet is confirmed, the object fingerprint of the gun or bullet and the purchaser's information are stored in association with each other. An investigation agency can easily obtain information regarding the owner of a leftover item (gun or bullet) left at a crime scene by transmitting the object fingerprint of the leftover item (gun or bullet) to the server device 10.

Investigative agencies can determine whether the bullet at the scene was fired from the suspect's gun by comparing the streaks left on the bullet with the streaks obtained by test-firing the suspect's gun. It is possible to confirm the facts. However, the investigating agency cannot determine the ownership of the bullets left at the scene through such comparison. On the other hand, in the dangerous goods management system according to the first embodiment, the investigation agency can identify the owner (purchaser) of the bullet remaining at the crime scene.

Additionally, the server device 10 stores the distribution route of hazardous materials. That is, in the dangerous goods management system according to the first embodiment, complete traceability of dangerous goods such as guns and bullets is ensured.

[Second embodiment]
Next, a second embodiment will be described in detail with reference to the drawings.

In the first embodiment, a case has been described in which an investigative agency requests the management center to provide information regarding the owner of a leftover item. In the second embodiment, a case will be described in which an investigative agency requests the management center to provide other information.

Note that the configuration of the hazardous materials management system according to the second embodiment can be the same as that of the first embodiment, so the explanation corresponding to FIG. 3 will be omitted. Furthermore, the processing configurations of the server device 10, the seller terminal 50, the investigative agency terminal 60, etc. according to the second embodiment can also be the same as those of the first embodiment, so a description thereof will be omitted.

Hereinafter, the differences between the first embodiment and the second embodiment will be mainly described.

The investigative agency terminal 60 according to the second embodiment may request the server device 10 to provide information regarding the distribution route of the left behind item (gun or bullet). In this case, the information provision request unit 403 transmits a “distribution route information provision request” including the object fingerprint of the leftover item to the server device 10.

Upon receiving the distribution route information provision request, the server device 10 (information provision control unit 205) reads the distribution route set in the distribution route field from the entry specified by object authentication. The information provision control unit 205 notifies the investigation agency terminal 60 of the read distribution route.

The information provision request unit 403 of the investigation agency terminal 60 provides the received distribution route to the investigator. For example, the information provision requesting unit 403 displays information regarding the distribution route on a display, or prints the information using a printer.

For example, the information provision requesting unit 403 displays information as shown in FIG. 24 on a display or the like. Investigators use the presented distribution routes in criminal investigations. For example, an investigator may interview a seller about the person who purchased a dangerous item.

Alternatively, the investigative agency terminal 60 may request the server device 10 to provide overall information regarding the belongings left behind. In this case, the information provision request unit 403 transmits a “remaining item information provision request” including the object fingerprint of the leftover item to the server device 10.

The information provision control unit 205 of the server device 10 that has received the request to provide information on the left behind reads the entry specified by object authentication from the database. The information provision control unit 205 transmits the information written in the read entry (manufacturer ID, distribution route, seller ID, owner identification information, etc.) to the investigation agency terminal 60.

The information provision requesting unit 403 of the investigation agency terminal 60 provides the received information (information regarding the belongings left behind) to the investigator, etc. For example, the information provision requesting unit 403 displays information as shown in FIG. 25 on a display or the like.

Alternatively, if the server device 10 stores the biometric information (facial image) of the dangerous object owner in the database, the server device 10 may also send the biometric information to the investigation agency terminal 60. The information provision requesting unit 403 of the investigative agency terminal 60 may perform a display including the received biometric information (facial image) (see FIG. 26).

As described above, the server device 10 according to the second embodiment can provide various information registered in the dangerous goods management database to investigative agencies and the like. Specifically, upon receiving a distribution route information provision request including an object fingerprint acquired from an object (leftover item), the server device 10 performs object authentication to determine the distribution route corresponding to the object fingerprint included in the distribution route information provision request. Identify. The server device 10 notifies the source (investigative agency terminal 60) of the distribution route information provision request of the identified distribution route. In this way, the dangerous goods management system according to the second embodiment can provide investigative agencies with information about the factory where the bullets, etc. were manufactured, their distribution routes, etc. regarding bullets and guns left at crime scenes.

Next, the hardware of each device that makes up the hazardous materials management system will be explained. FIG. 27 is a diagram illustrating an example of the hardware configuration of the server device 10.

Note that the configuration, operation, etc. of the hazardous materials management system described in the above embodiments are merely examples, and are not intended to limit the configuration, etc. of the system.

In the above embodiment, the operation of the dangerous goods management system was explained using guns and bullets as examples of dangerous goods. However, the hazardous materials targeted by the hazardous materials management system may be either guns or bullets.

In the above embodiment, a case has been described in which the distribution company terminal 40 of the distribution company transmits a "dangerous goods distribution notification" to the server device 10 in order to register the distribution route of the dangerous goods in the system. However, if there is no need to store the distribution route of dangerous goods, the distribution business terminal 40 does not need to send the dangerous goods distribution notification to the server device 10.

If there is no need to register the distribution route of dangerous goods in the system, gun manufacturers and bullet manufacturers can do so without sending dangerous goods identification information (gun serial number, bullet case case ID) to the server device 10. good. That is, the serial number of a gun and the case ID of a bullet case are not essential information for identifying the owner of a dangerous object.

In the above embodiment, it has been explained that the server device 10 requests an external server to make a determination using a blacklist. However, the server device 10 may perform the determination using the blacklist.

Alternatively, if laws and regulations do not provide for determination using a blacklist (confirmation that the purchaser of dangerous goods is not a criminal, etc.), the server device 10 does not need to perform determination using a blacklist.

When processing the sales propriety determination, if it is determined that the sale of dangerous goods is "not possible", the server device 10 may notify the seller terminal 50 of the reason for the sale of the dangerous goods being determined to be "not possible". Specifically, the server device 10 may notify the seller terminal 50 of the reason why the product is determined to be unsaleable, such as "failed to verify identity" or "listed on a blacklist." Alternatively, if the person who wishes to purchase dangerous goods is a person listed on the blacklist, the server device 10 stores information about the person who wishes to purchase dangerous goods (for example, name) and information about the purchasing agent (for example, store name and location) may be notified to the police, etc.

If a gun is left at a crime scene and a serial number can be obtained from the gun left behind, an investigator or the like of an investigative agency may input the serial number into the investigative agency terminal 60. The investigative agency terminal 60 may transmit a request for providing owner information including the serial number of the gun to the server device 10. The server device 10 may search the gun management database using the serial number as a key, and transmit the owner identification information of the corresponding entry to the investigating agency terminal 60. In other words, even if the serial number cannot be obtained from the gun left behind, the investigative agency can identify the owner of the gun by sending the object fingerprint obtained from the gun left behind to the server device 10. You can know.

In the above embodiment, a case has been described in which a gun management database and a bullet management database are configured inside the server device 10, but these databases may be configured in an external database server or the like. That is, some functions of the server device 10 may be implemented in another server. More specifically, if the above-mentioned "dangerous goods sales control section (dangerous goods sales control means)", "information provision control section (information provision control means)", etc. are implemented in any of the devices included in the system. That's fine.

Although the form of data transmission and reception between each device (for example, the server device 10 and the seller terminal 50) is not particularly limited, the data transmitted and received between these devices may be encrypted. Biometric information and the like are transmitted and received between these devices, and in order to appropriately protect this information, it is desirable that encrypted data be transmitted and received.

Although a plurality of steps (processes) are described in order in the flowcharts (flowcharts, sequence diagrams) used in the above description, the order in which the steps are executed in the embodiment is not limited to the order in which they are described. In the embodiment, the order of the illustrated steps can be changed within a range that does not affect the content, such as executing each process in parallel, for example.

The above embodiments have been described in detail to facilitate understanding of the present disclosure, and it is not intended that all the configurations described above are necessary. Further, when a plurality of embodiments are described, each embodiment may be used alone or in combination. For example, it is also possible to replace a part of the configuration of the embodiment with the configuration of another embodiment, or to add the configuration of another embodiment to the configuration of the embodiment.
