Below, an embodiment of a lost item management device, a lost item management method, a lost item management program, and a loss prevention tag according to the present invention will be described with reference to the drawings.

Fig. 1 is a diagram showing the overall configuration of a lost-item management system. As shown in Fig. 1, the lost-item management system includes a lost-item management device 10 and a loss prevention tag 50. The lost-item management device 10 is configured so that an intermediate device 60 (described later), a user device 70 carried by a user who is the owner of the loss prevention tag 50, and an electronic device 80 used by a third party can be connected to the lost-item management device 10 via a network.
The third party is an organization to which the owner of a lost item reports a lost item, such as the police, etc. The electronic device 80 is, for example, an information processing device such as a notebook PC or a desktop PC.

Figure 2 is a diagram showing an example of the hardware configuration of the loss prevention tag 50. As shown in Figure 2, the loss prevention tag 50 is equipped with, for example, a microcomputer 55. A series of processes for realizing various functions described below are stored, for example, in the form of a program in a secondary storage device 53 provided in the microcomputer 55, and are realized by the CPU (processor) 51 reading this program into the main memory 52 and executing information processing and calculation processing. In addition, the secondary storage device 53 provided in the loss prevention tag 50 stores information necessary to realize the lost item management method described below, such as a tag ID (tag identification information) uniquely assigned to the loss prevention tag 50.

The anti-loss tag 50 further includes a communication interface 56 and a speaker 57 .
The communication interface 56 functions as an interface for connecting to a network to communicate with other electronic devices and transmitting and receiving information. An example of wireless communication is communication using a short-distance communication line, and a specific example is Bluetooth (registered trademark).

The loss prevention tag 50 is attached to an item AZ that the owner does not want to lose, such as keys or a wallet. When the item AZ is not lost, the user device 70 carried by the owner and the loss prevention tag 50 attached to the item AZ are connected by a wireless line (e.g., Bluetooth (registered trademark)). In other words, the user device 70 and the loss prevention tag 50 are in a paired state. Here, the user device 70 may be any electronic device that the owner normally carries with them, such as a smartphone, tablet terminal, or notebook PC.

In contrast, if the owner loses an item, the loss prevention tag 50 will be removed from the communication range of the user device 70, causing wireless communication to be cut off. This will result in the pairing being cancelled. If communication with the user device 70 is cut off for a specified period of time, the loss prevention tag 50 will enter lost mode and send a location information notification request to nearby devices.

As shown in FIG. 1, if there are electronic devices A-D around the loss prevention tag 50 that can respond to a location information notification request, in other words, electronic devices A-D that can wirelessly connect to the loss prevention tag 50, the loss prevention tag 50 attempts to establish wireless communication with one of the electronic devices A-D. The electronic devices A-D are, for example, portable information processing devices such as smartphones and tablet terminals.

Here, electronic devices A to D are devices equipped with a program that can respond to a location information notification request when the request is received from the loss prevention tag 50. Among these electronic devices A to D, the electronic device that has established wireless communication with the loss prevention tag 50 is called the intermediary device 60.

When the intermediary device 60 establishes a wireless connection with the loss prevention tag 50, it responds to a request for location information from the loss prevention tag 50 by sending lost item notification information including location information, tag ID, and a list of communicable electronic devices (hereinafter referred to as the "peripheral device list") that are present in the vicinity of the loss prevention tag 50 to the lost item management device 10. For example, in the example of FIG. 1, information on electronic devices A to D is registered in the peripheral device list.

Here, the "location information" refers to location information obtained using a location detection function installed in the intermediary device 60, such as location information obtained using the Global Positioning System (GPS) or a mobile communication network.
In addition, in this embodiment, the "peripheral device list" is information that is created when the anti-loss tag 50 detects peripheral devices that can be connected to it and based on information about the detected peripheral devices, and is information that is provided from the anti-loss tag 50 to the intermediate device 60.

Figure 3 is a diagram showing the hardware configuration of the lost item management device 10. The lost item management device 10 is, for example, a cloud server, and as shown in Figure 3, includes a CPU 11, a main memory 12, a secondary storage device 13, and a communication interface 14. The lost item management device 10 may further include an input unit and a display unit. The input unit and the display unit may be provided in a remote location, and may be configured to be connected to the lost item management device 10 via a network to enable various input operations and display of data.

Figure 4 is a functional configuration diagram showing an example of the functions of the lost property management device 10 according to this embodiment. As an example, a series of processes for realizing the various functions described below are stored in the secondary storage device 13 or the like in the form of a program, and the CPU (processor) 11 reads this program into the main memory 12 and executes information processing and arithmetic processing to realize the various functions. The program may be pre-installed in the secondary storage device 13, provided in a state stored in another non-transient computer-readable storage medium, or distributed via wired or wireless communication means. Examples of non-transient computer-readable storage media include magnetic disks, magneto-optical disks, CD-ROMs, DVD-ROMs, and semiconductor memories.

As shown in FIG. 4, the lost item management device 10 includes, for example, a communication unit 21, a memory unit 22, a determination unit 23, a location information notification unit 24, and a support request unit 25. The lost item management device 10 may further include a user database 26 in which a user ID (personal authentication information) is registered, and a third-party organization database 27 in which authentication information of a third-party organization is registered. The user database 26 may also include a contact address, a corresponding tag ID, etc., associated with the user ID.

The communication unit 21 is connected to other devices via a network, for example, and exchanges information with them. For example, the communication unit 21 receives lost item notification information from the intermediary device 60 that has received a location information notification request from the loss prevention tag 50. As described above, the lost item notification information includes, for example, the location information of the intermediary device 60, the tag ID of the loss prevention tag 50, and a device list. The lost item notification information may further include time information.
The storage unit 22 stores the lost item notification information received from the intermediary device 60 .

Based on the latest lost item notification information including the common tag ID and previously received lost item notification information, the determination unit 23 determines whether or not the notification conditions for notifying the registration destination of the owner (user) of the loss prevention tag 50 of the latest location information of the loss prevention tag 50 are met. Details of the determination conditions will be described later.

When the determination unit 23 determines that the notification conditions are met, the location information notification unit 24 notifies the registration destination of the owner of the loss prevention tag 50 of the latest location information.

When the support request unit 25 receives a support request from the user device 70 used by the owner of the loss prevention tag 50 to the intermediary device 60, it transmits a support request notification to the intermediary device 60 that is the sender of the latest lost item notification information. In addition, the support request unit 25 may send a support request notification to the intermediary device 60 when the determination unit 23 determines that the notification conditions are satisfied, regardless of the support request from the user device 70.

The various processes executed by such a lost property management system will be explained below with reference to Figures 5 to 8.

FIG. 5 is a timing chart of the loss prevention tag 50, the intermediary device 60, and the lost item management device 10 in the lost mode.
First, when the owner (user) loses the possession AZ to which the loss prevention tag 50 is attached, wireless communication between the loss prevention tag 50 and the user device 70 is interrupted, and if this communication interruption state is maintained for a predetermined period of time, the loss prevention tag 50 enters lost mode.

In the lost mode, as shown in FIG. 5, the loss prevention tag 50 transmits a location information notification request to nearby devices. This location information notification request is repeatedly transmitted from the loss prevention tag 50 to the surroundings at a specified time interval. As a result, lost item notification information is intermittently sent from the intermediary device 60 that has accepted the location information notification request to the lost item management device 10. Here, the intermediary device 60 is the electronic device that accepts the location information notification request from the loss prevention tag 50 at each time and establishes wireless communication, and is not necessarily always the same electronic device.

Next, the lost-item management method executed in the lost-item management device 10 will be described with reference to Figs. 6 to 7. Figs. 6 to 7 are flowcharts showing an example of the processing procedure of the lost-item management method. The series of processes shown below are realized by the CPU 11 reading a program stored in the secondary storage device 13 (see Fig. 3) into the main memory 12 and executing information processing and calculation processing.

The lost item management device 10 determines whether or not lost item notification information has been received (SA1 in FIG. 6). As a result, if lost item notification information has not been received (SA1: NO), the device enters a standby state until it is received. On the other hand, if lost item notification information has been received (SA1: YES), the device determines whether or not it is the first time lost item notification information has been received (SA2). Specifically, the device determines whether or not lost item notification information having a tag ID in common with the received lost item notification information is stored in the memory unit 22, and if not, determines that it is the first time it has been received.

If this is the first time that lost item notification information has been received, it can be assumed that the user (owner) has lost the property near the location information included in the lost item notification information. In addition, since the location where the property was lost is not yet in a stalking situation, there is no problem in notifying the user of this location information. Therefore, if this is the first time that lost item notification information has been received (SA2: YES), the lost item management device 10 obtains the user's registration address associated with the tag ID and sends a loss notification to the obtained registration address (SA5). As a result, for example, the location information, tag ID, time information, etc. included in the first lost item notification information are notified to the user.

On the other hand, if it is not the first time that the signal is received in step SA2 (SA2: NO), it is determined whether or not a location notification request has been received from the user (SA3). A location notification request is a request for the lost item management device 10 to notify the latest location information when the user realizes that an item has been lost. The location notification request includes, for example, tag specific information (e.g., tag ID) for identifying the tag and user identification information (hereinafter referred to as "user ID") for identifying the user. Note that if the lost item management device 10 holds information that associates the user ID with the tag ID of the loss prevention tag 50, the user ID may be used as the tag specific information, in which case the tag specific information can be omitted.

As a result, if a location notification request has been received (SA3: YES), it is then determined whether the notification conditions are met (SA4). Specifically, it is determined whether (1) the loss prevention tag has been moved from the location where it was lost, or (2) there is no overlap between the devices included in the latest device list and the devices included in the previously received device list. If at least one of these two conditions is met, it is determined that the notification conditions are met. In the following, in this embodiment, an example will be described in which the device list included in the previously received lost item notification information is used as the previously received device list.

For example, in the case of "(1) when the loss prevention tag has not moved from the place where it was lost," it can be assumed that a specific person (e.g., a stalking victim) is not moving while carrying the loss prevention tag 50. Furthermore, if the location information has not changed from the place where it was lost, the location information of the place where it was lost has already been notified to the user when the lost item notification information is first received, so there is no inconvenience in notifying the user of the latest location information.

Furthermore, "(2) when there is no overlap between the devices included in the latest device list and the devices included in the previously received device list" means that none of the electronic devices included in the previous device list are currently present in the vicinity of the loss prevention tag 50. For example, in a stalking situation, the electronic devices carried by the stalking victim will always be present in the vicinity of the loss prevention tag 50, so this does not meet the above condition (2). For this reason, a situation where the above condition (2) is met can be considered to be a situation where no stalking is occurring.

As a result, if the notification conditions are not met (SA4: NO), the process proceeds to step SA6 without notifying the user of the location information. On the other hand, if the notification conditions are met (SA4: YES), a loss notification is made (SA5). As a result, the user is notified of, for example, the location information, tag ID, time information, etc. contained in the latest lost item notification information.

Then, the lost item management device 10 stores the lost item notification information in the memory unit 22 (SA6) and returns to step SA1.

On the other hand, if a location notification request has not been received in step SA3 (SA3: NO), it is determined whether a request for assistance has been received from the user (SA7 in FIG. 7). This request for assistance is, for example, a request sent from the user device 70 used by the user who owns the loss prevention tag 50, and requests assistance from the intermediary device 60 via the lost item management device 10.

If the lost item management device 10 has received a support request (SA7: YES), it performs support request processing (SA8) and then proceeds to step SA6 in FIG. 6. The support request processing will be described later.

On the other hand, if a request for assistance has not been received (SA7: NO), it is determined whether a request for providing location information has been received from the electronic device 80 of the third party (see FIG. 1) (SA9). This request for providing location information is information transmitted from the electronic device 80 of the third party to the lost property management device 10 when the user, who is the owner of the loss prevention tag 50, reports the loss of the property AZ to the third party.
The request for providing location information includes the user ID (personal authentication information) of the user who is the owner of the loss prevention tag 50, authentication information of a third party organization, and the like.

When the lost property management device 10 receives a request for providing location information (SA9: YES), it authenticates the authentication information of the third party included in the request for providing location information (SA10). Specifically, it determines whether the authentication information of the third party is registered in the third party database 27. As a result, if it is registered, it determines that the authentication is successful (SA10: YES), and then performs user authentication using the user ID (SA11). Specifically, it determines whether the user ID is registered in the user database 26. As a result, if it is registered, it determines that the authentication is successful (SA11: YES), and performs location notification based on the latest lost property notification information to the third party (SA12). As a result, the location information, tag ID, time information, etc. included in the latest lost property notification information are notified to the electronic device 80 of the third party (see FIG. 1). After performing the location notification, it proceeds to step SA6 in FIG. 6, and the lost property notification information is stored in the memory unit 22.

Furthermore, if a request for location information has not been received from the third party agency (SA9: NO), if third party agency authentication has not been successful (SA10: NO), or if user authentication has not been successful (SA11: NO), the process proceeds to step SA6 in FIG. 6 without notifying the third party agency of the location information, stores the lost item notification information in the memory unit 22, and returns to step SA1. In this way, by authenticating the third party agency and authenticating the user, it is possible to prevent the third party agency from obtaining location information of the loss prevention tag 50 without the user's consent. This makes it possible to prevent things like illegal investigations by the police.

Next, the support request process executed in step SA8 described above will be described with reference to FIG. 8. FIG. 8 shows an example of a timing chart of the user device 70, the lost item management device 10, the intermediary device 60, and the loss prevention tag 50 when the support request process is executed.

First, when the lost item management device 10 receives a request for assistance from the user device 70 (SB1), it transmits the request for assistance to the intermediary device 60 (SB2). When the intermediary device 60 receives the request for assistance, it transmits a warning sound output command to the loss prevention tag 50 (SB3). When the loss prevention tag 50 receives the warning sound output command, it outputs a warning sound from the speaker 57 (see FIG. 2). This makes it possible to notify people around the loss prevention tag 50 of the presence of the loss prevention tag 50.

When the intermediary device 60 receives a request for assistance, it displays a message such as "Do you agree to the lost item assistance?" on the display or the like, and asks the user of the intermediary device 60 whether or not to accept the assistance. In response, when the user of the intermediary device 60 accepts the assistance by operating an input unit or the like, the intermediary device 60 sends an assistance acceptance notification to the lost item management device 10 (SB4). When the lost item management device 10 receives the assistance acceptance notification, it notifies the user device 70 of the location based on the latest lost item notification information (SB5).

In this way, when a request for assistance is made from the user device 70, an alarm sound is output from the loss prevention tag 50, and all peripheral device users who are candidates for the intermediary device 60 are asked whether or not they would like to grant assistance. Only if assistance is granted is location information sent to the user device 70. As a result, if a stalking act is occurring, a request for assistance is also displayed on the stalking victim's electronic device, making it possible to notify the stalking victim of the stalking act. This makes it possible to hinder the accomplishment of the stalking act and to prevent location information from being sent for the purpose of stalking.

As described above, the lost item management device, lost item management method, lost item management program, and loss prevention tag according to this embodiment provide the following advantages.

When the lost item management device 10 receives lost item notification information from the intermediary device 60, including location information, the tag ID of the loss prevention tag 50, and a list of devices present in the vicinity of the loss prevention tag, the lost item management device 10 determines whether or not the notification conditions are met based on the latest lost item notification information including the common tag ID and the previously received lost item notification information. Specifically, the lost item management device 10 determines that the notification conditions are met if (1) the loss prevention tag 50 has not moved from the location where it was lost for a predetermined time or more, or (2) there is no overlap between the devices included in the latest device list and the devices included in the previously received device list.

In this way, by determining whether the notification conditions are met, it is possible to confirm whether the loss prevention tag 50 is likely to be used for stalking purposes. Then, after confirming that the loss prevention tag 50 is not being used for stalking purposes, the location information contained in the latest lost item notification information is sent to the registration destination of the owner of the loss prevention tag 50, so that the loss prevention tag 50 can be prevented from being used for stalking purposes.

Furthermore, according to this embodiment, it is determined that the notification condition is met when at least one of the above two conditions is met. For example, if an anti-loss tag is lost inside a moving object such as a train, the location will change and the above condition (1) will no longer be met. Even in such a case, if the above condition (2) is met, it is possible to notify the owner of the location information. In this way, by setting two conditions, it is possible to more reliably prevent stalking while notifying the owner of the location information.

Furthermore, when lost item notification information is received for the first time, the location information included in the lost item notification information can be considered as location information of the location where property AZ was lost. Since the location where property AZ was lost is not yet in a stalking situation, no inconvenience will arise if this location information is notified to the user, who is the owner. Therefore, by notifying the owner of the location information of the location where property AZ was lost, the owner can be notified early that property AZ has been lost.

When the lost item management device 10 receives a request for assistance from the user device 70 to the intermediary device 60, it sends an assistance request notification to the intermediary device 60, which is the sender of the latest lost item notification information, and when it receives an assistance acceptance notification from the intermediary device 60, it notifies the registration destination of the owner of the loss prevention tag of the latest location information.

In this way, after receiving permission to assist from the user of the intermediary device 60, the latest location information is notified to the owner, thereby preventing the loss prevention tag 50 from being used for stalking purposes.

In addition, when the lost item management device 10 receives a request for location information from a third-party organization, it performs third-party organization authentication and user authentication, and then notifies the third-party organization of the latest location information, so that the location of the lost item can be notified promptly and the anti-loss tag 50 can be prevented from being used for stalking purposes.

Other Embodiments
For example, in the above-described embodiment, the lost item management device 10 determined whether or not the notification conditions are met (see, for example, step SA4 in FIG. 6 ). However, instead of this, the notification condition (2), i.e., whether or not there is any overlap between the devices included in the latest device list and the devices included in the previously received device list, may be determined in the loss prevention tag.

9 is a functional block diagram of a loss prevention tag 50a according to another embodiment of the present invention. As shown in FIG. 9, the loss prevention tag 50a includes a notification request unit 61, a list creation unit 62, and a determination unit 63.
The various functions described below are stored in the secondary storage device 53 provided in the microcomputer 55 in the form of a program, for example, and are realized by the CPU (processor) 51 reading this program into the main memory 52 and executing information processing and arithmetic operations.

When communication with a user device 70, which is an electronic device of the owner, is interrupted for a predetermined period of time, the notification request unit 61 transitions to a lost mode and transmits a location information notification request to peripheral devices.
The list creation unit 62 creates a device list of connectable electronic devices that are present in the vicinity when a location information notification request is issued.
The determining unit 63 determines that the notification condition is satisfied when there is no overlap between the devices included in the latest device list and the devices included in the previously acquired device list.

In this way, when the determining unit 63 determines that the notification condition is satisfied, a location information notification request with information indicating that the notification condition is satisfied is sent to the intermediary device 60. As a result, lost-item notification information with information indicating that the notification condition is satisfied is sent from the intermediary device 60 to the lost-item management device 10.
According to this aspect, when information indicating that the notification condition is satisfied is added to the lost-item notification information, the lost-item management device 10 can omit the determination process of step SA4 in Fig. 6. This makes it possible to reduce the processing load of the lost-item management device 10.

Although the present invention has been described above using each embodiment, the technical scope of the present invention is not limited to the scope described in the above embodiment. Various modifications or improvements can be made to the above embodiment without departing from the gist of the invention, and the forms in which such modifications or improvements are made are also included in the technical scope of the present invention. In addition, the above embodiments may be combined as appropriate.
Furthermore, the processing flow described in each embodiment is also an example, and unnecessary steps may be deleted, new steps may be added, or the processing order may be rearranged, without departing from the spirit of the present invention.

For example, in each of the above-described embodiments, the previously received device list is used to determine whether the notification condition (2) described above is satisfied, but this is not limited to the above example. For example, a device list from any timing, such as the first time or the time before last, may be used to determine whether a device is duplicated.

This allows for emphasis on the anti-stalking function, such as emphasizing the tracking function for lost items based on whether nearby devices have been replaced immediately after the item is lost, or notifying the location only if the device has been replaced with one from a certain time ago. In addition, when only comparing with the first time, a stalker can stalk a victim by sneaking a loss prevention tag 50 that is already in lost mode into the victim's luggage, but by combining this with a device duplication determination using a device list at any time thereafter, it is possible to more reliably determine whether the loss prevention tag 50 is being used for stalking. In addition, by comparing the devices included in the latest device list with the devices included in each of multiple device lists received in the past, it becomes possible to control the time for location tracking.

In addition, in each of the above-described embodiments, the anti-loss tag 50 generates a "peripheral device list" and transmits it to the intermediary device 60, but this is not limited to the example. For example, the peripheral devices may be generated by the intermediary device 60.

In the above-described embodiment, when a request for providing location information is received from the electronic device 80 of a third party, third party authentication and user authentication are performed, and if these authentications are successful, a location notification is sent, but this is not limited to the example. For example, third party authentication or user authentication may be omitted, or both third party authentication and user authentication may be omitted.

In addition, in the above embodiment, one of the above conditions (1) and (2) may be set as the notification condition, and it may be determined whether the set notification condition is met.
