  As described above, an object of the present invention is to provide a more convenient information communication system using a terminal that can be carried by a user. Specifically, it aims to provide the following mechanism and framework.

  In the present invention, as will be described in an embodiment described later, the group and service classification information exchanged by the close proximity wireless communication is used as a communication ID, and information communication such as data broadcast and group cast by the short distance wireless communication is executed. It has a function that can.

  Moreover, it is possible to link with the coupon for service and map information by proximity | contact wireless as it is using ID of the taken in information, and such an application can be constructed | assembled easily.

  In the conventional communication technology, when acquiring unique individual information such as ID and IP, it is generally acquired using a communication line (for example, automatic IP address acquisition by DHCP). As an example in which the communication line is not directly used, device setting information is stored in advance in a USB memory or the like, and the memory is attached to the communication device to perform static device setting.

  Although these methods are simple, they cannot cope with the situation in which the information to be set changes dynamically, and there is no communication infrastructure, and terminal ID allocation in an environment where user terminals communicate with each other There was a problem that it could not be used.

  In addition, as a system, conventionally, attribute information exchange between defined terminals and an integration method for information attributes have not explicitly existed. That is, a conventional general technique is a system that operates using the same standardized device (such as an IC card).

  On the other hand, in the present invention, the unique ID at the communication level is integrated and managed including the system level, so that the user can easily include the service using the near field radio and the near field radio. An environment that can be used can be presented, and it is an object of the present invention to provide such an environment.

  In order to solve the above-described problems, the present invention proposes various systems centering on terminals called secure tags, devices therefor, and the like.

A principle
Secure Tag A schematic diagram showing the appearance of a secure tag is shown in FIG. The secure tag 10 as shown in this figure generally employs the following specifications.

(1) Shape and external specifications ・ Approximately business card size is adopted.
A liquid crystal display 12 is provided, and predetermined information can be presented to the user.
A portable battery-driven electronic device that is generally so-called portable and mobile (portable) electronic device that can retain power by charging the battery from the outside. By incorporating such a battery, it is portable and can be used even in the event of a disaster or the like.

・ Equipped with a daily waterproofing function.
-It has buttons to enable external button operations for scrolling the screen and inputting user's intentions such as decisions. This button may include an arbitrary number of buttons, but typically, as shown in FIG. 10, it is preferable that the secure tag 10 includes three buttons 12. For example, a determination button 14a, a right scroll button 14b, and a left scroll button 14c.

  ・ Equipped with I / F (interface) for power supply and PC connection communication. For example, a general USB (Universal Serial Bus) interface is suitable for this application. In particular, a wired interface is preferred for this application.

  -It has a near field communication (NFC) (I / F (interface)). This interface is also used in, for example, Felica (registered trademark).

  ・ Equipped with a short-range wireless I / F. In general, this is an interface using the 920 to 950 Mhz band. This interface is also used in a system called an “active tag system” which is a kind of RFID. Conventionally, a 900 Mhz band has also been used.

  -It has GPS (Global Positioning System). The position information can be detected by this GPS. This GPS corresponds to a preferred example of the position detection means in the claims.

  ・ Equipped with an acceleration sensor. With this acceleration sensor, it is possible to detect and judge whether it is moving / not moving. As will be described later, SOS can be issued when it is detected that this sensor is not moving. Details thereof will be described later.

  ・ Equipped with beep sound generation means. This beep sound is composed of a predetermined small speaker or the like.

  The secure tag has a characteristic configuration as described above, in particular, having three functions of 1: near field radio (NFC), 2: near field radio, and 3: display.

  In the secure tag, three basic interfaces are I / F (interface) (for example, USB) for power supply and PC connection communication, near field radio (NFC), and near field radio I / F, It is.

  This secure tag may be simply called a tag. The secure tag corresponds to a preferred example of the terminal in the claims.

(2) Operational specifications ・ Equipped with the proximity wireless (NFC) function, the following operations are possible.

(A) Data exchange with a smartphone is possible.
(B) Group registration / participation between secure tags is possible.
(C) It can be used as an IC card.
・ By using short-distance radio (specific low-power radio) such as 920M band radio that has been available since FY2013, secure tags in a short-distance area (several hundred meters) can distribute information / Acquisition is possible. As a communication type in this case, a local area service different from the carrier communication service becomes possible by performing data distribution mainly including broadcast / multicast data.

  Such a broadcast has been used in the call connection part, but has never been used in the data communication part.

  Furthermore, in the field of broadcasting, it has traditionally been sent out by "broadcast" (sending side) and performing return communication (replying side) using other carriers (Internet, mobile phone network, etc.). However, it has not been known so far to communicate data using broadcast communication in the field of communication. In particular, one of the technical features of this secure tag is that it can send and reply in the same frequency band.

  -It has a function to decrypt and display private confidential information encryption information. Therefore, it is possible to hold medical chart information in the secure tag, and as a result, the secure tag can be used as a hospital card.

  That is, the secure tag is provided with means for decrypting the encrypted data, and the encrypted personal information stored inside can be decrypted and displayed (display 12).

  ・ Since the secure tag can be operated by simple operation and has a screen (preferably a touch panel capable of touch operation), it can be used by users of a wide range of ages, from children to the elderly. Is possible. It is also possible to use secure tags instead of amulets when going to dangerous areas such as mountain climbing. Since it is structured in the size of a business card and lightweight as described above, it can be used as a “talisan” for reasons such as being easy to carry even by children and the elderly.

  For example, when a distress or the like occurs, an alarm can be generated on the secure tag by an external beacon or the like. In addition, when the alarm is not stopped for a certain period of time (usually when the user stops it by a button operation or the like), it is also preferable that the secure tag automatically performs SOS notification. It is preferable to include the position information of the secure tag by GPS in the SOS issue. If the position information is sent to the smartphone, the position can be shown on the map on the smartphone. As a result, it is possible to specify the position of the victim. This is based on the assumption that when a user is distressed, the user loses consciousness, cannot move, or the like. Specific details will be described later.

  The present invention proposes a system and method for providing two types of services, infrastructure services and services between tags, in order to solve the above-mentioned problems. A specific example of the operation will be described in detail.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings.

  FIG. 1 shows an external view of a system of a regional distributed wireless network which is a preferred embodiment of the present invention. This regional distributed wireless network corresponds to a preferred example of the distributed network in the claims.

  As shown in this figure, in this regional distribution network, base stations 20 are distributed in a predetermined region. In particular, the base station 20 or the like installed on the building roof is referred to as “(1) NerveNet compatible device installed on the roof” in the figure. This base station covers a cell of a 920 Mhz band, and in FIG. 1, the area covered by each base station 20 is schematically represented by a circle and is referred to as a “920 Mhz cell”. A database 22 (described as “DB” in the figure) is provided in association with the base station 20, and stores various management information and various regional information to be provided. Further, the base stations 20 may be connected by an intranet 24.

  In the drawing, the portions expressed as circle 1, circle 2,... Are represented as (1), (2),. The same applies to circles 3 to 8.

  Each base station 20 includes a wireless AP (access point) 20a, and transmits and receives radio waves using the wireless AP 20a.

  In the 920 Mhz cell covered by the base station 20, it is possible to use infrastructure services using the secure tag 10 and the IC card 11 described above. In FIG. 1, this is referred to as “(2) 920 Mhz wireless terminal connection + IC card wireless use”.

  In addition, the system of this regional distributed wireless network can be linked to a cloud service, and can also be connected to a smartphone via it. This is referred to as “(3) Smartphone connection” in FIG.

  In addition, this regional distributed wireless network system is also connected to a signage terminal 30 and can display a predetermined advertisement by remote control. This is referred to as “(4) Signage terminal connection” in FIG.

  Further, it is preferable that the secure tag 10 is not necessarily carried but is fixedly arranged at a predetermined place. For example, it is also convenient to configure so that citizens can freely operate by arranging them at public offices or public facilities. This is referred to as a “fixed installation tag” in FIG.

  Further, as described above, the secure tag 10 can perform inter-tag communication using NFC or the like. By this inter-tag communication, it is possible to use services such as group emergency notification and smartphone application cooperation (see FIG. 1). A smartphone is an abbreviation for a smartphone, and an application here is an abbreviation for an application program that runs on the smartphone. A service used by such so-called inter-tag communication is referred to as an inter-tag service.

  In the present embodiment, the operation will be mainly described focusing on a technique for providing the infrastructure service and the inter-tag service.

  Note that the communication line connecting the base stations 20 and the wireless APs 20a in the regional distributed network of FIG. 1 corresponds to a preferred example of the network in the claims.

1. Infrastructure System Service (1) Infrastructure Tag Management FIG. 2 shows a time chart of the processing flow of a tag management service, which is a type of infrastructure service. The tag here refers to the secure tag 10, and the same applies hereinafter. As shown in FIG. 2, the tag management is a processing operation that should be called tag connection confirmation.

  First, the base station 20 checks the connection at the IP level with respect to the wireless AP (access point) 20a. Then, various parameters are set for the wireless AP 20a.

  Here, the base station 20 is a part that plays a role as a “wireless device”, and the wireless AP 20a is a part that actually transmits and receives radio waves.

  The secure tag 10 performs an AP scan, that is, a scan of a wireless access point, and checks whether there is a wireless AP 20a that can be accessed in the vicinity. When the wireless AP 20a returns a scan response to this scan, the secure tag 10 can know the presence of the surrounding wireless AP 20a. In general, such an operation is often called connection confirmation.

  The AP scan refers to a message or packet transmitted for scanning. The scan response refers to a message or packet that the wireless access point that has received the AP scan transmits to the secure tag.

  In FIG. 2, there is a broken line at the bottom of the tag 10, but the left side represents a relatively hardware operation of communication. The right side of the broken line represents a relatively software operation. The operation from hardware (hardware system) is represented as “device” in FIG. 2, and the operation from software (software system) is represented as “application” in FIG. This application represents an application program that operates on the secure tag 10.

  On the other hand, when the operation is started, the base station 20 first detects a connected terminal. The terminal in this case is basically the secure tag 10, but there is a possibility that another terminal (for example, a smartphone or the like) is also connected. In this embodiment, in order to make the description easy to understand, the case of the secure tag 10 is basically described as the “terminal” (unless otherwise specified).

  The base station 20 periodically detects the terminal as described above. First, a connection terminal detection request is transmitted to the wireless AP 20a at the start of operation (see FIG. 2). In response to this, the wireless AP 20a transmits a connection detection packet by broadcast. When the secure tag 10 receives this connection detection packet, the management APP (application) 40 filters the packet with reference to the ID filter table 42 and then confirms the connection derived from the service used by itself. If the packet is a packet, the connection response packet is returned as unicast. The management application is an application program that manages services that runs on the secure tag 20. Further, the ID filter table is a table for selecting only communication related to the ID filter table, and the table is configured on a general storage unit. As the storage means, an EEPROM, a flash memory, or the like is generally suitable.

  The connection response packet includes identification data for specifying the secure tag 10. Here, the identification data is data for identifying the secure tag. In some cases, the identification data is also identification data of the owner's individual and may be personal data.

  When receiving the connection response packet, the wireless AP 20a transmits a connection terminal detection response to the base station 20. This connection terminal detection response includes the identification data. That is, this is a response message that reports what terminal (secure tag 10) is connected. Receiving this, the base station 20 can confirm which secure tag 10 is located in which wireless AP 20a cell.

  The connection terminal detection request and the connection terminal detection response are messages (or packets) transmitted and received at the start of service operation. After that, the connection terminal detection request and the connection terminal detection response are periodically issued and what secure tag 10 exists at which position. We are checking in a timely manner. The actual cycle varies depending on the service and the type of target terminal. In the present embodiment, the description has been made on the assumption that the secure tag 10 is basically a mobile terminal. However, depending on the application, a fixed terminal such as a disaster radio / disaster prevention radio may be included. In the case of a fixed terminal, it may be possible to lengthen the cycle. In the case of a mobile terminal, it is generally preferable to set a short cycle.

  In this way, “tag management”, which is one of infrastructure services, is executed. Note that although communication between the wireless AP 20a and the secure tag 10 is performed using the 920 MHz band (FIGS. 1 and 2), it is of course preferable to use other frequency bands. For example, it is also preferable to use a 700 MHz band. In general, a frequency band less than 1 GHz called a so-called sub-Ghz band is suitable. This is a type of communication generally referred to as short-range wireless or the like, but other types of wireless communication may be used.

  In FIG. 2, POE means Power over Ethernet (registered trademark) and represents a mechanism for supplying power to the wireless AP 20a through Ethernet. The same applies to FIG. 3 and FIG.

(2) Infrastructure information distribution (one-to-many)
As a second type of infrastructure service, a time chart of a flow of processing of an information distribution (one-to-many) service is shown in FIG.

  As in the case of FIG. 2, the secure tag 10 performs AP scan, that is, scan of a wireless access point, and checks whether there is a wireless AP 20a that can be accessed in the vicinity. When the wireless AP 20a returns a scan response to this scan, the secure tag 10 can know the presence of the surrounding wireless AP 20a.

  The information distribution (one-to-many) service is a so-called broadcast service, and is a service for distributing predetermined distribution information by broadcast.

  First, the base station 20 issues a distribution information setting request to the wireless AP (access point) 20a. Information to be distributed (referred to as distribution information) is transmitted to the wireless AP (access point) 20a. In response, if there is at least one secure tag 10 to be connected, the wireless AP 20a stores the above distribution information in an information distribution packet and distributes it by broadcast (see FIG. 3). After the distribution, the wireless AP 20a transmits a distribution information setting response to the base station 20. After this distribution information setting response message is returned, the base station 20 transmits the next distribution information setting request to the wireless AP 20a. In other words, the distribution information setting request is not transmitted unless a distribution information setting response is returned.

  The secure tag 10 appropriately receives information that can be received if distributed. This reception operation is received by the information reception application program 44 (simply referred to as the information reception application 44) in the secure tag 10. The secure tag 10 does not return a reception response (referred to as ACK or the like). Since it is a one-to-many broadcast communication, it is not preferable from the viewpoint of traffic that a large number of reception responses (ACK) are returned, and therefore no reception response (ACK) is returned.

  The secure tag 10 also includes an ID filter table 42 for designating what type of information is received. That is, the information reception application 44 searches the ID filter table 42 and receives only the information distribution packet having the ID stored in the ID filter table 42 in advance.

  In order to perform such selective reception, the user preferably sets the information distribution type in advance for the secure tag 10. That is, the user registers in the secure tag 10 an ID that represents the type of information that the user wants to receive. This registered content is stored in the ID filter table 42 inside the secure tag 10 and used by the information receiving application 44 as described above.

  This registration operation is preferably performed from the smartphone 28 or the like, for example. The smartphone 28 and the secure tag 10 are connected by NFC, and the ID entered on the screen of the smartphone 28 is sent to the secure tag 10. It is also preferable to perform the registration operation via a personal computer. The secure tag 10 is preferably provided with a USB as described above, and can be easily connected to a personal computer via the USB. Therefore, it is also preferable to send the ID input by the user from the personal computer to the secure tag 10 for registration.

  In this way, one-to-many information distribution is possible. In FIG. 3, only one secure tag 10 is depicted, but in practice, a plurality of secure tags 10 are allowed to exist in the area (cell) covered by the wireless AP 20a. This realizes “one-to-many” information distribution.

(3) Infrastructure information transmission (one to one)
FIG. 4 shows a time chart of the flow of information distribution (one-to-one) service processing as the third type of infrastructure service.

  This one-to-one information transmission is a service that can distribute information from the secure tag 10 side. The wireless AP 20a basically distributes by broadcast, but the secure tag 10 transmits data by unicast.

  Here, “one-to-one” means that one secure tag 10 communicates with one wireless AP 20a. This is different from “one-to-many” (explained in (2) above) in which one wireless AP 20a and a plurality of secure tags 10 communicate.

  This information distribution can be considered in various usage forms. As a typical example, a secure tag 10 is installed (fixed) in a public facility, and predetermined information transmission can be performed one-to-one from the fixed secure tag 10. Conceivable. In this case, it is also preferable that the user transmits information to the fixed secure tag 10 via the fixed secure tag 10 by NFC communication using another secure tag 10b owned by the individual. It is also preferable that information is transmitted by causing the fixed secure tag 10 to read the IC card.

  As shown in FIG. 4, as in the case of FIG. 2 and FIG. 3, the AP scan from the secure tag 10, that is, the scan of the wireless access point, is performed, and is there a wireless AP 20a accessible to the surroundings? It is confirmed whether or not.

  To perform one-to-one information transmission, one fixed secure tag 10 first transmits a notification packet by unicast. This transmission is performed by the issuing APP 46 in the fixed secure tag 10. For example, data provided from an external personally owned secure tag 10b or the like is stored in the notification packet. Alternatively, the data may be data generated or detected by the fixed secure tag 10 itself. It depends on the application. For example, the secure tag 10 is fixedly installed at a station or the like, and when the user passes through the secure tag 10, the user passes by the communication with another secure tag 10 b (or IC card) owned by the user. There are cases where services such as distribution of the history to a station database are provided. In the case of such a service, data such as the passage time and the ID of the user who has passed are stored in the notification packet. In addition to the station, a bus stop is also suitable.

  The notification packet is transmitted by communication from an external IC card or the like. This means that there was a request for notification from the outside. In other words, communication with the IC card is a notification request. In some cases, the communication with the IC card is a browsing request (in this case, the browsing request). In case of browsing request. There may be a configuration in which the issued packet is an empty packet that does not include data.

  When the notification packet is received by the wireless AP 20a, the wireless AP 20a transmits a notification request to the base station 20. In the base station 20, a group information table 50 is provided, and a group to be notified is searched from the group information table 50. This is called group information search 52, and the group information search application program stored in the base station 10 executes this group information search 52. As a result of this group information search 52, various processes are possible. Typically, depending on the purpose (application), a service that distributes information only to members of a predetermined group is also conceivable. In addition, since it has been well known that a service is provided for a group or for each group, detailed description thereof is omitted.

  In any case, the result is distributed from the base station 20 by some processing. For this purpose, first, the base station 20 transmits a notification response to the wireless AP 20a. The wireless AP 20a distributes the notification packet by unicast in accordance with the notification response message. The notification packet is received by a predetermined secure tag 10, and the information display APP 48 (information display application 48) inside the packet is displayed on the display 12.

  Here, the secure tag 10 to be received may be the secure tag 10 of the user who has distributed information from the fixed secure tag 10 or the secure tag 10 of another person.

  As described above, when the person who has passed the station wants to confirm the passing information of the station, the same person may view the data distributed to him / herself. A service for transmitting information to others is also conceivable. Who receives it depends on its use and the purpose of the service it provides.

  Note that the information display APP 48 also uses the ID filter table 42 to filter and display only the information that it uses. The filtering setting is also performed by each user using the smartphone 28 or the IC card as described above.

  As the service, it is possible to consider various types of provided services as described above. In particular, when information is transmitted (one-to-one) using an IC card, it is preferable to transmit data related to the IC card. For example, when the IC card is a point card for shopping, it is preferable to display the number of points on the point card using this information transmission (one-to-one).

  FIG. 4 shows an example of the group information table 50 and group information search based on the group information table 50. However, the present invention is not limited thereto, and various applications can be realized as long as the application is related to the IC card as described above.・ Can be used.

  As shown in FIG. 4, in a normal time, providing a service for browsing group information when an IC card is used is an example of a suitable service. Even if there is no display means such as an IC card, the use of the fixed secure tag 10 makes it possible to check the points as described above. In addition, it is an example of a service that is preferably configured so that group information can be browsed and shared when an information terminal (individually owned secure tag 10 or smartphone 28) is used.

  Also, as shown in FIG. 4, in the event of a disaster, providing a service that can issue and view safety information when using an IC card is an example of a suitable service. Even if there is no display means such as an IC card, it is possible to confirm the safety of the family by using the fixed secure tag 10 provided in the public facility. Also, if you can register your safety using an IC card, it will be very convenient. In addition, in the event of a disaster, it is preferable that the safety information can be issued and viewed in the same manner even when an information terminal (privately owned secure tag 10 or smartphone 28) is used. It is an example of a service.

  Note that the group information table 50 and the like in FIG. 4 may be located anywhere on the network. In FIG. 4, for the sake of convenience, the wireless AP 20a is depicted as being closest to the wireless AP 20a, but it may actually be located anywhere.

  Further, in this embodiment, the base station 20 or its peripheral device is described as acting as a server for the application, but in reality, the server may be located anywhere on the network. .

  In this embodiment, a service combining a predetermined server (regardless of location), a wireless AP 20a, and a secure tag 10 is described. Here, one of the characteristic features of the present embodiment is a mechanism in which a service is provided by communication between the wireless AP 20a and a secure tag. Since the wireless AP 20a and the secure tag 10 connected to the wireless AP 20a are used, it is possible to automatically receive services using an IC card or the like. For example, as described above, it is possible to realize a service in which data when a user passes through a station or the like is accumulated, and the user can check his / her own passage history and the like later.

  The contents of the issued packet vary depending on its purpose and application. When the user's passage history is used as an accumulation specification, the passage information becomes the contents of the notification packet. This information is notified to the user by the notification packet described above. By the way, especially in a station, it may be assumed that the user does not take a train but only wants to have a passing history. In this case, a configuration may be adopted in which an empty packet that does not include the passage history is transmitted as the notification packet. When an empty notification packet is transmitted, it is also preferable that the notification response and the notification packet store the user's passage history and transmit the notification response and notification packet.

Variations of the secure tag 10 The secure tag 10 may be installed in a public institution such as a station as described above, and there is also a secure tag 10 carried by each user. These are functionally similar, but there may be some differences from the viewpoint of “installation / carrying”. For example, when it is fixedly installed in a public institution, it may be operated by an AC power source, and in the case of a portable type, it may be configured to be operated by a battery. Although there are such differences, the basic functions are the same.

Mode of Secure Tag 10 As described above, the secure tag 10 communicates with the wireless AP 20a, and also communicates with other secure tags 10 (see NFC etc. in FIG. 4). The mode for performing communication with the wireless AP 20a is referred to as “infrastructure mode”, and the mode for performing communication between the secure tags 10 is referred to as “inter-tag mode”.
For example, in the “reporting”, in the infrastructure mode, the secure tag 10 reports only to the wireless AP 20a.

2. Inter-tag service (inter-tag mode)
(1) Inter-tag information distribution A chart showing the operation of inter-tag information distribution, which is one of inter-tag services, is shown in FIG.

  This information distribution is communication used for services such as providing (reporting) information on store services and traffic information on trains and buses at storefronts, stations, bus stops, and the like.

  FIG. 5 shows a chart of information distribution operation between the secure tag 10a and the secure tag 10b.

  In this figure, the secure tag 10a side is the side that distributes information. The secure tag 10a receives information to be distributed, for example, in cooperation with the smartphone 28a, and stores the information in advance in storage means in the secure tag 10a. The data receiving operation and storing operation are executed by an information issue APP (information issue application) 60 in the secure tag 10a. This operation is shown in FIG. 5 “(1) Distribution data registration through smartphone cooperation”.

  Next, in “(2) Start distribution” in FIG. 5, data distribution is started. When data distribution is started, first, as shown in “(3) AP mode setting” in FIG. 5, the secure tag 10a shifts to a mode called AP mode. In the AP mode, the operation like the wireless AP 20a as described above is performed, and the other secure tag 10b looks like the wireless AP 20a.

  In other words, as described above, the other secure tag 10b performs an AP scan (represented by (4) AP scan in FIG. 5) in order to confirm the surrounding wireless AP 20a. Thus, it is going to perform what is called a connection check.

  In response to this AP scan, the secure tag 10a set to the AP mode executes “(5) scan response” in FIG. 5, and as if it is a wireless AP 20a with respect to the other secure tags 10b. Perform the action. Then, after the scan response is returned to the other party's secure tag 10b, the data to be distributed is distributed by broadcast. At this time, the service ID is attached to the data. Such a data distribution operation is represented by “(5) B information distribution (broadcast): Service ID addition” in FIG.

  Next, the secure tag 10a transmits an AP leave issue (represented by “(6) AP leave issue” in FIG. 5), and informs the secure tag 10b that it is leaving the AP mode. Thereafter, the secure tag 10a cancels the AP mode setting (represented by “(7) AP setting cancellation” in FIG. 5).

  What is characteristic in the present embodiment is that the secure tag 10 temporarily plays a role similar to that of the wireless AP 20a in inter-tag communication, but returns to the normal secure tag 10 after information distribution is completed. It is. This is different from the “fixed” wireless AP 20a. In the secure tag 10 that is assumed to be moving, the area covered by itself (that is, the “cell” area) changes. This is because their role tends to become unstable.

  As shown in FIG. 5, it is also preferable to adopt a configuration that does not issue a withdrawal request when distributing disaster information or the like. This is because it is preferable to always be able to deliver and receive disaster information at any time in the event of a disaster. This will be described later.

In addition, when the AP mode is canceled once, when the AP mode is shifted again, it is preferable that a time interval of about 30 seconds be opened. This is to limit the number of secure tags 10 that shift to the AP mode to some extent, and to stabilize the communication state and traffic. In this embodiment, a time interval of about 30 seconds is opened, but a shorter time interval or a longer time interval may be used depending on the application.
These operations on the secure tag 10a side are executed by the above-described information issue APP 60.

  On the other hand, in the secure tag 10b on the receiving side, the information receiving APP 62 operates, and performs the above-described (4) AP scan and (5) receives a scan response.

  Further, the information receiving APP 62 receives the information distributed in the above-mentioned “(5) B information distribution”. At this time, the information reception APP 62 refers to the ID filter table 42 and receives only information including the IDs in the table. That is, the information distribution is received only when the ServiceID in “(5) B information distribution (broadcast): ServiceID addition” in FIG. 5 is stored in the ID filter table 42. This is to eliminate malicious information and unwanted information. As described above, the ID filter table 42 can set an ID from an external smartphone 28b or the like (see FIG. 5). When the user starts a predetermined setting application from the screen of the smartphone 28, the user can see the information distribution type setting screen of the secure tag 10. By selecting an ID corresponding to a desired service or information from this screen, the ID can be registered in the ID filter table 42 in the secure tag 10. Thus, it is possible for the user to receive only the information he / she desires.

(1) -a About disaster information (emergency information), etc. (operation in disaster mode)
As described above, in the case of disaster information or the like, it is preferable that the secure tag 10 does not leave the AP mode (referred to as “maintaining the AP mode”).

  For example, when an ambulance crew carries the secure tag 10a, it is necessary to always deliver various information related to disasters from the secure tag 10a to the surroundings, which may be preferable. Therefore, when an emergency crew or the like carries the secure tag 10a, it is also preferable that the secure tag 10a is maintained in the AP mode by the operation of the emergency crew who is the user. The information transmission APP 60 also executes such operation input and the like. The setting of “not leaving the AP mode” is preferably performed by operating from the smartphone 28 a held by the emergency personnel.

  In this case, in the “disaster mode”, it is also preferable to set the secure tag 10b of the general user other than the emergency crew so as not to shift to the AP mode. This is to give priority to the distribution of disaster information and emergency information by emergency personnel.

  Various methods can be considered for the transition to the disaster mode. For example, reception of a beacon signal indicating the transition to the disaster mode may be received, or the transition to the “disaster mode” is made when disaster information is transmitted by the “inter-tag information distribution” described in this chapter. Is also suitable. It is preferable that the information receiving APP 62 shown in FIG. 5 executes the operation for shifting to the disaster mode by receiving such “signal” or “disaster information”.

  For example, when the secure tag 10a fixedly arranged at the storefront of a store intends to distribute a product advertisement using “inter-tag information distribution”, it shifts to the AP mode each time. When a signal is received, the AP mode is not shifted for a predetermined period. With such a configuration, it is possible to effectively use the frequency band at the time of disaster. It is common to divide the frequency into predetermined bands and determine the use of each band. On the other hand, it is a characteristic matter in the present invention that the use of a predetermined frequency band is changed according to the situation or the user is restricted.

(1) -b Recovery from disaster mode Various operations can be considered to recover from the disaster mode to the normal mode. For example, it is also preferable to adopt a configuration such as returning to normal operation after a lapse of a predetermined time after the disaster information disappears. For example, the secure tag 10b that has received the disaster beacon signal is preferably operated in the disaster mode for a predetermined period (for example, one day) and restored to the normal operation after the predetermined period has elapsed. In this case, as long as the disaster beacon is continuously received within a predetermined period, the normal operation is not restored and the disaster mode is maintained. Such an operation is executed by the information receiving APP 62 of the secure tag 10b. In addition, it is also preferable to separately deliver instruction information for returning to normal operation from the disaster mode. The reception information APP62 of the secure tag 10b that has received such instruction information is restored from the disaster mode to the normal operation.

  What is characteristic in the present embodiment is that terminals (secure tags 10) that can use the frequency band on a case-by-case basis are limited. As a result, the frequency band can be effectively used.

(1) -c Safety information in the disaster mode When the information receiving APP 62 in the secure tag 10b receives the disaster information, the secure tag 10b shifts to the disaster mode, but at the same time, the safety SOS issue APP (safety SOS). (Notification application) 66 is activated and issues the safety or SOS response of the user of the secure tag 10b (see FIG. 5).

  The secure tag 10 is equipped with an acceleration sensor and can detect whether the user is moving or stationary. If it is stationary for a predetermined time, it is considered that it is fainting, and the safety SOS notification APP 66 performs SOS notification. This notification is performed using a proximity wireless I / F such as NFC. On the other hand, when the acceleration sensor detects an acceleration other than 0 and determines that the user is active, safety notification is performed. This safety notification is preferably a message including the name of the user and the current position.

  Such a safety notification is received by a safety SOS reception APP (safety SOS reception application) 64 of another secure tag 10a in the vicinity, and the safety of the person is confirmed. In this case, if the report is an SOS report, the safety SOS reception APP (safety SOS reception application) 64 of the secure tag 10a transfers the information to the hospital, police, fire department, etc. In position, it can tell if it is likely to be in danger.

(2) Inter-tag Group Information Sharing A chart showing the operation of group information sharing, which is the second type of inter-tag service, is shown in FIG.

  In this group information sharing, first, group registration is performed between the secure tags 10 using a proximity wireless I / F such as NFC. As a result, the secure tag 10a and the secure tag 10b in FIG. 6 are registered in the same group.

  For example, the secure tag 10a to be the master of the group is defined, and the other secure tag 10b that wants to join the group is registered with the secure tag 10a to be the master using NFC or the like, and receives the group ID. Keep it. This ID is registered in the ID filter table 42 in advance. As will be described later, when the information receiving APP 62 receives the information distribution, only the information distribution having the same ID as the ID registered in the ID filter table 42 is received. Therefore, the ID filter table 42 can be regarded as a means for storing membership information.

  In a state where such group registration has been performed, as described above, the secure tag 10b performs a connection check (3) AP scan as appropriate as a normal operation. On the other hand, the secure tag 10a in the SP mode returns (4) a scan response. Thus, the secure tag 10a functions as an access point when viewed from the secure tag 10b.

  In the secure tag 10a, a user presses the emergency notification button so-called in order to make an emergency notification to a group member (a user registered for the group is called a member). To do.

  In the present embodiment, an example of long pressing of the emergency notification button is shown, but it is preferable to apply the determination button 14a in FIG. Of course, it is also preferable to provide another new emergency notification button not shown in FIG.

  Although the emergency notification button is referred to here, an information distribution button may be used, and if it is used only for group information distribution, it is also preferable to adopt a name such as a group information distribution button.

  An emergency notification is a notification, for example, in the case of a group of searchers who are searching for a lost person, when one of the members of the group finds a lost person, he / she knows his / her position to other searchers in the vicinity. . In this case, the emergency notification includes its own location information. Of course, other emergency notifications are also acceptable. In FIG. 6 of the present embodiment, “emergency notification” is shown as an example of the information distribution target, but other contents and other objects may be used. An example of an application in which an emergency notification is an information distribution target will be described later with reference to FIG. Any information can be distributed as long as it is distributed toward the group.

  Then, the information issuing APP 60 of the secure tag 10a detects the long press and sets the secure tag 10a to (2) AP mode (see FIG. 6). In this way, the secure tag 10a is shifted to the AP mode, and the information issue APP 60 returns (4) a scan response.

  The secure tag 10a that has shifted to the AP mode performs information distribution by broadcast in order to distribute information of desired emergency information (see (5) in FIG. 6). At this time, unlike FIG. 5, GroupID is added to the information delivery message.

  In the secure tag 10 b, the information reception APP 62 refers to the ID filter table 42 and receives only information distribution with the same ID as the ID stored in the ID filter table 42. In particular, when receiving the emergency information, the information receiving APP 62 sounds a so-called beep when receiving the emergency information to inform the user that there has been an emergency communication. By hearing this sound, the user can know the position of the secure tag 10a that delivered the emergency communication with GPS information. This is a case where location information is included in the emergency notification as described above. In the case of an emergency notification including such position information, for example, it is preferable to display the position on a map as shown in FIG. As a result, the user (for example, another search member) of the secure tag 10b who has received the emergency notification can know the position of the search member who has transmitted the emergency notification, and can rush to that location.

  Next, the information reception APP 62 in the secure tag 10b that has received the emergency notification information distribution returns (6) a reception response to the secure tag 10a side. This returned (6) reception response includes personal information, for example, member information and position information of the search member (see FIG. 6). (6) It is also preferable that the reception response includes not only personal information but also a predetermined message, text data, and other data.

  When receiving the reception response, the secure tag 10a that has distributed the emergency communication information (8) cancels the AP mode. This operation is executed by the information transmission APP 60 in the secure tag 10a. By receiving this reception response, the information issue APP 60 can know that the information distribution has been successful, and as a result, (8) the AP mode can be canceled (see FIG. 6).

  However, even if “(6) reception response” is not returned, (8) the AP mode is once canceled and (7) AP leave is transmitted to the outside. This is basically configured so that emergency communication is performed once (one-shot) because it may interfere with other people's emergency communication if the AP status is prolonged. It is.

  Note that (7) AP leaving is transmitted to inform the secure tag 10b that the access point (AP) has disappeared. If “(6) reception response” is not returned, it is preferable to notify the user by displaying that fact on the display 12. In addition, when it is determined that the user is necessary, the emergency notification button is pressed and held again, and (5) information distribution for sharing emergency communication group information is performed again.

Member Search Mode In the present embodiment, it is also preferable that the secure tag 10b continuously searches for group members. This is done, for example, to check whether all search members are present. This continuous mode is called a member search mode. When the user sets the member search mode to be valid in the secure tag 10, the information receiving APP 62 of the secure tag 10 continuously executes the AP scan. As a result, it is possible to sequentially detect search members who have found a victim and are making emergency communications. In the normal mode that is not the member search mode, it is preferable to execute the AP scan at a frequency of about once every 30 seconds in consideration of the sleep state.

In addition, in the above-described example, it is described that the AP mode is canceled even when “(6) reception response” is not returned, but it is rare that the AP mode is not actually returned. This is because (3) AP scan is returned, (4) a scan response is returned, and (5) information distribution is performed thereafter, so that at least one person is considered to have a receiver. In other words, (3) The information notification APP 60 is in a waiting state until an AP scan comes. Since (3) an AP scan is sent by someone and (5) information distribution is performed, it is generally considered that the secure tag 10 that one person receives is in the vicinity.

  In addition, as described above, in (5) information distribution (see FIG. 6) in inter-tag group information sharing, it is preferable that the position information of the search team member is included in the message. Even if a name or the like is included, it is preferable. It is also preferable that text data / message data such as “2 injured persons” is included in the message. Moreover, it is suitable even if the photograph data etc. of an injured person are included.

3. Application Examples About four examples of applications using the above-described infrastructure communication and inter-tag communication will be described.

(1) -a Application for finding missing persons for ambulance crew (Fingerprint and personal information registration I / F are also required)
FIG. 7 shows an example of an application for ambulance crews who search for a fallen person or an unknown person.

  As shown in FIG. 7 (1), the ambulance crew carries the smart phone 28, and this smart phone 28 is connected to the secure tag 10b by USB. The ambulance crew operates the smartphone 28 to transmit a disaster mode beacon signal from the secure tag 10b. This is described as 920 Mhz · 20 mW in FIG. 7, but other frequency bands may be used, and any communication may be used as long as the communication is called short-range wireless communication I / F. For example, a signal in a so-called sub-Ghz band is preferable.

  The disaster mode beacon signal is transmitted when the secure tag 10b shifts to the AP mode (access point mode) as described in the inter-tag information distribution (FIG. 5) and the like. As a result, even when the base station 20 and the wireless AP 20a are not present in the vicinity, it is possible to search for a person who has fallen down (“individual” in FIG. 7A). In particular, in a tunnel or the like, there are many cases where radio waves do not reach even if there is a wireless AP 20a in the vicinity. Even in such a case, according to the present embodiment, it is possible to search for a person who has fallen and is unknown.

  The disaster mode beacon is for notifying a disaster, and it is generally preferable that a device that receives the disaster mode beep or an emergency warning sound indicating an emergency disaster. In addition to the beep sound, a message such as “Please evacuate” or “Please gather at the evacuation site XX” may be included, and it is also preferable to display the message on the receiving device.

  On the other hand, when the secure tag 10a carried by “individual” in FIG. 7 receives this disaster mode beacon, the information receiving APP 62 (see FIG. 6) emits a beep and confirms that the disaster information has been notified. To inform. The disaster mode beacon issued by the secure tag 10b corresponds to a kind of disaster information notification. The disaster information notification may be sent from another communication device.

  When the beep sounds, the individual presses a predetermined button. Then, the information reception APP 62 (see FIG. 6) mutes the beep sound. On the other hand, when the button is not pressed and the acceleration sensor has not reacted for a certain time, the safety / SOS issue APP 66 (see FIG. 5) issues the SOS issue. This SOS issue includes at least personal information of the individual and position information. Further, the SOS issue may suitably include other various messages, text data, and the like. The SOS issue may include a time when the acceleration sensor has not responded, or may include time information indicating when the last response occurred. In addition, if the temperature of the place is included in the SOS report, it is possible to know the situation and environment of the unknown person who has fallen down.

  This SOS issue is received by, for example, the secure tag 10b. Reception is performed by the safety SOS reception APP 64 (see FIG. 5). The received data is stored in a predetermined storage means in the secure tag 10a and can be viewed from the external smartphone 28. The state of browsing is shown in FIG.

  FIG. 7 (1) shows a state in which the smartphone 28 extracts the above-described SOS issue information from the secure tag 10b connected via USB and displays the information on the display. As shown in FIG. 7A, it is preferable to display a human icon representing a person on the map information (see FIG. 7A). In this case, the position of the icon on the map is determined based on the position information included in the SOS issue described above. Further, as shown in FIG. 7A, when an emergency crew member who is the owner of the smartphone 28 touches the screen, personal information regarding the humanoid icon at the touched position is displayed as text data or the like. The personal information preferably includes an ID, name, address, emergency contact information, and the like.

  In particular, in the present embodiment, even when there are a plurality of unknown persons who have gone down, it is possible to confirm the plurality of persons on the display of the smartphone 28 (see FIG. 7 (1)). It is possible to improve. In FIG. 7A, the case where there is one “individual” is depicted, but in reality, there may be a plurality of “individuals” shown in FIG. 7A and their secure tags 10a. That is, the secure tag 10b receives SOS notifications from a plurality of secure tags 10a.

In addition, in the example of FIG. 7 (1), the smartphone 28 is connected to the secure tag 10b via USB, but may be connected via NFC other than USB, or may be connected via another interface. Absent.

  Further, in FIG. 7 and the above description, it is called “disaster mode beacon”, but this may be anything as long as disaster information is notified.

  Further, in FIG. 7 and the like, it is described as 920 Mhz, but other frequency bands may be used. In general, short-range radio such as a so-called sub-Ghz band is preferable.

(1) -b Application for grasping personal information of a person who is not known to fall and fall An example of an application for obtaining personal information of a person who has been discovered in FIG. 2).

  In FIG. 7 (2), an application is described in which a fingerprint of a person who has been transported and is unknown is read in a hospital and personal information inside the secure tag 10 is read via NFC.

  In FIG. 7 (2), it is assumed that the person who has been transported is unknown, and the personal information cannot be heard verbally.

  First, as shown in FIG. 7 (2), the fingerprint of the person who has been transported and is unknown is read by the fingerprint scanner 70, and the fingerprint data is read by the hospital terminal 72. The fingerprint scanner 70 and the hospital terminal 72 are connected by USB. Those who are unsure of going down may be fainted, and are often unable to talk. Even in such a case, by using the fingerprint scanner 70, it is possible to extract the information of the person who has fallen and is unknown.

  On the other hand, the personal information is assumed to be encrypted and stored in the personal information database 22b of the base station 20. In the present embodiment, an operation for extracting personal information from the personal information database 22b will be described.

  Now, the hospital terminal 72 (who operates the fingerprint data) that has acquired the fingerprint data uses the fingerprint data and the ID read out from the secure tag 10d held by the person who has fallen and lost in the personal authentication database 22b. The personal information of the corresponding individual can be browsed. Details will be described in the next section of personal information database j.

Personal Information Database The personal information database 22b stores personal information, and browsing is a database that requires the following three types of key information.

(A) fingerprint data;
(B) a hospital terminal 72;
(C) a secure tag 10d (see FIG. 7 (2)) owned by the person who has fallen or fallen;
It is.

  When these three types of information are gathered, (a) an individual with matching fingerprint data exists in the database, and (b) when the hospital terminal 72 is authorized and access is permitted, the personal information database 22b It is possible to extract personal (encrypted) personal information. The encrypted personal information read out in this way is decrypted using the key in the secure tag 10d, and the obtained original data is displayed on the display of the secure tag 10d. .

  That is, the personal information stored in the personal information database 22d is encrypted, but the key for decrypting it is stored in the secure tag 10d.

The personal information database 22b in the present embodiment is a database attached to the base station 20 located in the mesh network, but may be located anywhere as long as it can be accessed from the hospital terminal 72.

  The personal information here is preferably so-called chart information. For example, as shown in FIG. 7, medical history, common drugs, presence / absence and type of allergy, blood type, presence / absence of organ transplantation, etc. are examples of suitable personal information. These are displayed on the display of the secure tag 10d that is personally owned by the person who is unclear. Although depending on the system configuration, it is also preferable that the hospital terminal 72 reads the key from the personal secure tag 10d to decrypt the personal information and display it on the display of the hospital terminal 72.

  Thus, according to the present embodiment, personal medical record information can be easily shared among a plurality of medical facilities.

  In order to handle such personal information, it is necessary to pay sufficient attention to leakage of personal information. However, in this embodiment, the person is present (confirmed by fingerprints), is a medical facility (hospital terminal It can be browsed only when the requirement that the user's secure tag 10d is present (personal information can be decrypted with the key of the secure tag 10d) is satisfied. Unauthorized leakage can be prevented.

  Here, the description has focused on “browsing”, but if the hospital terminal 72 is configured so that additional entry can be made in personal information, so-called chart information sharing becomes extremely easy.

  Note that the secure tag 10d that is privately owned by the person who is unclear is connected to the secure tag 10c on the hospital terminal 72 side using NFC. With this configuration, the hospital terminal 72 sends the personal information read from the personal information database 22d via the hospital-side secure tag 10c to the personally-owned secure tag 10d via the hospital-side secure tag 10c. be able to. As a result, the personally owned secure tag 10d can decrypt the received personal information using the internally held key and display it on the display 12.

Other biometric information In the above-described example, the personal information database 22 uses fingerprint data. However, it is also preferable to use a database that can be accessed and viewed using other biometric information (retina, vein pattern, etc.). It is. According to such biometric information, it is possible to accurately confirm that the person is there.

Registration of personal information In the above-described embodiment, the ID of the personal secure tag 10d is referred to. In practice, however, a kind of encryption key is stored inside the personal secure tag 10d. Is preferred. First, the individual registers his / her personal data in the personal authentication database 22b through the hospital terminal 72 at any medical institution. At this time, the user also registers his / her “fingerprint data” using the fingerprint scanner 70. The personal information is encrypted and stored in the personal information database 22d. At the time of registration, a key is generated, and the key is stored in the private secure tag 10d. In this way, the personal information cannot be browsed unless the secure tag 10d is provided.

It is preferable to update / add personal information as follows, for example.
That is, when a doctor or the like prescribes some medicine for the individual (person who is unclear), the prescribed medicine or the like is input on the hospital terminal 72.
