(Embodiment)
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same element through the whole description of embodiment. In summary, an unauthorized use detection system 100 according to an embodiment of the present invention is obtained by adding an algorithm for detecting unauthorized use (an unauthorized use detection program 200) to the conventional location information notification system 10. Therefore, in the following, first, the conventional location information notification system 10 will be described, and then the unauthorized use detection system 100 of the present invention will be described.

(Conventional location information notification system)
FIG. 1 is an explanatory diagram of a conventional position information notification system 10. FIG. 2 is an explanatory diagram of a situation in which the conventional location information notification system 10 has been used illegally. (A) is a diagram showing a situation in which the wireless communication terminal B is held in a bag or the like, and (b) is an unauthorized figure. It is a figure which shows the condition which is browsing using the terminal.

As shown in FIG. 1, a conventional location information notification system 10 is carried by a wireless communication terminal B that is carried by a moving person 1 such as an elderly person, and a parent 2 such as a parent with respect to the person 1. The guardian terminal C that can view the detection data registered in S and the guardian 1 moving toward the destination are fixed in advance in the vicinity of the route to the destination so that they can be detected at the required point. A base station terminal H carried by a pedestrian 3 that may be installed at a plurality of times or may pass the protected person 1 and a management server S capable of storing information transmitted from the base station terminal H. .
Further, in the position information notification system 10, a position for enabling the base station terminal H, the guardian terminal C, and the management server S to refer to the position information P such as the movement history of the wireless communication terminal B from the guardian terminal C. An information notification program has been introduced.

The wireless communication terminal B transmits the wireless communication terminal identification information IDb unique to the terminal periodically (for example, once every few seconds) in a short range (for example, 30 m to 50 m) around the wireless communication terminal B. Short-range wireless communication means capable of doing so may be provided. The short-range wireless communication means includes, for example, a communication device that enables communication by Bluetooth Low Energy (BLE) and a power supply, and includes wireless communication terminal information Ib having wireless communication terminal identification information IDb (UUID, Major value, Minor value). Can be transmitted periodically with low power (for example, once every few seconds). Note that Bluetooth is a registered trademark.
In addition, the wireless communication terminal B periodically transmits the terminal-specific wireless communication terminal identification information IDb (for example, once every few seconds) in the range of a long distance (for example, 1 km) around the wireless communication terminal B. Long-distance wireless communication means capable of doing so may be provided. The long-distance wireless communication means includes, for example, a communication device that enables communication by Low-Power Wide-Area (LPWA) such as LoRa and a power source, and the wireless communication terminal information Ib having the wireless communication terminal identification information IDb is reduced. It can be transmitted periodically with electric power (for example, once every few seconds).

  The base station terminal H has the base station identification information IDh and can receive the wireless communication terminal information Ib having the wireless communication terminal identification information IDb transmitted from the wireless communication terminal B. The base station terminal H may be, for example, a mobile terminal such as a smartphone, and may be a fixed terminal fixed or installed in a structure (such as a living room, a building entrance / exit, a road intersection, or a transportation facility). . The base station terminal H may be capable of acquiring the position information P of the base station terminal H by GPS or the like.

  The guardian terminal C includes communication means and a monitor for inquiring the management server S for location information P such as a movement history of the wireless communication terminal B and referring to the management server S.

  The management server S can store information transmitted from the base station terminal H. Further, the management server S transmits position information P such as a movement history of the wireless communication terminal B mutually authenticated with the guardian terminal C to the guardian terminal C in response to a request from the guardian terminal C.

  When the base station terminal H carried by the pedestrian 3 enters the wireless communication detection range A of the wireless communication terminal B carried by the protected person 1, the wireless communication terminal identification information IDb issued from the wireless communication terminal B The base station terminal H receives the wireless communication terminal information Ib having The base station terminal H transmits the wireless communication terminal information Ib having the received wireless communication terminal identification information IDb to the management server S together with the wireless communication reception time t, the position information P, the base station identification information IDh, and the like. Note that the position information P transmitted to the management server S is indirectly obtained from a relay station (not shown) between the base station terminal H and the management server S even if it is not directly obtained from the base station terminal H. You may do it.

  Therefore, the conventional position information notification system 10 allows the guardian 2 to access the management server S using the guardian terminal C that has been mutually authenticated in advance with the wireless communication terminal B in a timely manner. Data at the time of detection such as the reception time t can be viewed as a movement history of the person to be protected 1.

  However, the conventional location information notification system 10 may be used illegally as described below, for example.

  As shown in FIG. 2A, the malicious person 4 approaches the other person 5 and the other person 5 carries the unauthorized wireless communication terminal X that has been mutually authenticated against the unauthorized terminal Q in advance. Sneak away to the bag you want to go and leave. The unauthorized terminal Q has a function equivalent to that of the guardian terminal C. That is, the location information notification program for allowing the unauthorized terminal Q to refer to the location information P such as the movement history of the wireless communication terminal X illegally held by the unauthorized terminal Q is introduced in the same manner as the guardian terminal C. ing. Similarly to the base station terminal H, the unauthorized terminal Q has the base station identification information IDh, and the wireless communication terminal information having the wireless communication terminal identification information IDx transmitted from the unauthorized wireless communication terminal X. Ix can be received and position information P can be acquired.

  Then, since the situation is similar to the situation shown in FIG. 1, as shown in FIG. 2 (b), the malicious person 4 is improperly authenticated by the wireless communication terminal X that has been illegally held in advance in a timely manner. By accessing the management server S using Q, it is possible to view the detection time data such as the position information P and the wireless communication reception time t as the movement history of the other person 5. This is not desirable from a crime prevention point of view.

(Unauthorized Use Detection System of the Present Invention)
Therefore, the unauthorized use detection system 100 according to the embodiment of the present invention suppresses unauthorized use as follows. In summary, the unauthorized use detection system 100 according to the embodiment of the present invention includes the above-described conventional location information notification system 10 (at least a wireless communication terminal B, a guardian terminal C, a base station terminal H, and a management server S). System) to which a base station terminal Y carried by another person 5 and a program (algorithm) for detecting unauthorized use (unauthorized use detection program 200) are added. X is detected.

FIG. 3 is an explanatory diagram of the location information notification system 10 in which the unauthorized use detection system 100 of the present invention is introduced. FIG. 3A is a diagram showing a situation in which a wireless communication terminal X held illegally is held in a bag or the like. (B) is a figure which shows the condition which is going to browse using the fraudulent terminal Q.
As shown in FIGS. 3A and 3B, the unauthorized use detection system 100 in the location information notification system 10 is capable of periodically transmitting wireless communication terminal information Ix having wireless communication terminal identification information IDx. The wireless communication terminal X held by the wireless communication terminal X and the wireless communication terminal information Ix having the base station identification information IDy and the wireless communication terminal identification information IDx transmitted from the unauthorized wireless communication terminal X can be received. The base station terminal Y that can acquire the position information P and the management server S that can store the information transmitted from the base station terminal Y are provided.
Here, the other person 5 needs to carry the base station terminal Y (the base station terminal Y into which the unauthorized use detection program 200 is introduced) that constitutes the unauthorized use detection system 100.
In addition, in FIG. 3 (a) and FIG.3 (b), illustration of the other base station terminal H and the other radio | wireless communication terminal B is abbreviate | omitted.

  Then, as shown in FIG. 3 (a), as in the situation of FIG. 2 (a), the malicious person 4 approaches the other person 5 and has the illegality that has been mutually authenticated against the unauthorized terminal Q in advance. A situation is assumed in which the wireless communication terminal X that has been used is held by a bag or the like carried by another person 5 and left.

  Then, the wireless communication terminal X held illegally and the base station terminal Y carried by the other person 5 are close to each other (the base station terminal Y is in the wireless communication detection range A from 30 m to 50 m, for example) Or within the communicable distance range by the short-range communication means of the wireless communication terminal X held illegally, or within the communicable distance range by the long-range communication means of the wireless communication terminal X illegally held Therefore, the base station terminal Y carried by the other person 5 is within the wireless communication detection range A of the wireless communication terminal X held illegally and held illegally. The wireless communication terminal information Ix having the wireless communication terminal identification information IDx issued from the wireless communication terminal X is continuously received for a predetermined time. In addition, within the wireless communication detection range A, the base station terminal Y carried by the other person 5 may receive wireless communication terminal information Ib from the wireless communication terminal B (not shown), and other base stations The station terminal H (not shown) may receive the wireless communication terminal information Ib from the wireless communication terminal B, but the illustration description is omitted in FIGS. 3 (a) and 3 (b).

  The base station terminal Y transmits the wireless communication terminal information Ix having the received wireless communication terminal identification information IDx to the management server S together with the wireless communication reception time t, the position information P, the base station identification information IDy, and the like. Note that the position information P transmitted to the management server S is indirectly obtained from a relay station (not shown) between the base station terminal Y and the management server S even if it is not directly obtained from the base station terminal Y. You may do it.

  Here, in the case of normal use in FIG. 1, a passing pedestrian 3 enters the wireless communication detection range A (about 30 to 50 m) of the wireless communication terminal B owned by the person 1 to be protected and then exits. The time until is not so long (for example, 5 minutes). Therefore, in FIG. 3, the base station terminal Y owned by the other person 5 is illegally held because it has been received from the wireless communication terminal X held illegally over a predetermined time (for example, 5 minutes). Can be estimated.

  Therefore, based on the empirical / statistical viewpoint as described above, the unauthorized use detection system 100 determines that the state in which the wireless communication terminal X and the base station terminal Y that are illegally held are close to each other. When it exceeds Tref (for example, 5 minutes), it is detected that it is illegally used.

  Specifically, the base station terminal Y associates the wireless communication reception time t, which is the time when the wireless communication terminal information Ix is received, with the combination of the wireless communication terminal identification information IDx and the base station identification information IDy, and the wireless communication detection information And the unauthorized use detection system 100 refers to the wireless communication detection information, and the duration T during which the combination of the wireless communication terminal identification information IDx and the base station identification information IDy continues is the preset setting. An unauthorized use is detected when the time Tref is exceeded.

  Here, the base station terminal Y (for example, an application in the mobile phone) refers to the wireless communication detection information, and the duration T in which the combination of the wireless communication terminal identification information IDx and the base station identification information IDy continues to be the same. However, it may be detected that it has been illegally used when a preset time Tref is exceeded. When the base station terminal Y bears the calculation processing related to detection, the load on the CPU and the memory of the management server S can be reduced.

  Further, the management server S refers to the wireless communication detection information, and the duration T during which the combination of the wireless communication terminal identification information IDx and the base station identification information IDy continues is in excess of the preset set time Tref. Therefore, it may be detected that unauthorized use has been made. Since the management server S bears the calculation processing related to detection, the load on the CPU and memory of the base station terminal Y can be reduced.

  Furthermore, the unauthorized use detection system 100 includes a guardian terminal C having guardian identification information that is mutually authenticated with the specific wireless communication terminal identification information IDb in the wireless communication terminal B. With reference to the detection information, the same combination of the wireless communication terminal identification information IDx and the base station identification information IDy continues to be detected over a preset time Tref, and the wireless communication terminal identification information IDx and the base station identification If the combination of information IDy is not a combination of specific wireless communication terminal identification information IDb and guardian identification information, it may be detected that the information is illegally used.

  As a result, in the case of a combination of specific wireless communication terminal identification information IDb and guardian identification information, where a close state is expected to continue for a long time, it is excluded from the case where it is detected that it is illegally used. , The accuracy of determination of unauthorized use is improved.

  In addition, the unauthorized use detection system 100 or the unauthorized use detection program 200 is illegally used when the base station terminal Y receives a radio wave having a predetermined strength or more emitted by the unauthorized wireless communication terminal X for a predetermined number of times. It is good also as what detects that it exists. As a result, receiving the wireless communication terminal information transmitted from the wireless communication terminal X that has been illegally held periodically more than a predetermined number of times is equivalent to exceeding the preset set time and being illegally used. Can be detected. In addition, since the radio wave intensity that changes in accordance with the positional relationship between the wireless communication terminal X and the base station terminal Y held illegally is used, the proximity between the wireless communication terminal X and the base station terminal Y held illegally is used. The state can be grasped more accurately and it can be detected that it has been used illegally.

Further, the unauthorized use detection system 100 or the unauthorized use detection program 200 includes the wireless communication terminal X that can periodically transmit the wireless communication terminal information Ix having the wireless communication terminal identification information IDx, and the base station identification information IDy. The base station terminal Y that can receive the wireless communication terminal information Ix having the wireless communication terminal identification information IDx transmitted from the wireless communication terminal X and can acquire the position information P, and the information transmitted from the base station terminal Y And a fraudulent terminal Q having fraudulent terminal identification information IDq capable of browsing the position information P of the fraudulently held wireless communication terminal X. Then, the unauthorized use detection system 100 refers to the wireless communication detection information, continues to detect the same combination of the wireless communication terminal identification information IDx and the base station identification information IDy over a preset time Tref, and The position information P of the wireless communication terminal X which is different from the base station identification information IDy and the unauthorized terminal identification information IDq and is illegally held from the location where the unauthorized terminal Q is different from the location of the base station terminal Y at high frequency. In the case of referring, it may be detected that unauthorized use has been made.
In addition, the case where the location information P of the wireless communication terminal X that is illegally held at high frequency here is referred to is illegally held more than a specific number of times set in advance within a specific time set in advance. This means that the position information P of the wireless communication terminal X is being referred to. The location here may be, for example, an area (cell) covered by one base station owned by a mobile phone operator.
That is, the state in which the wireless communication terminal X and the base station terminal Y held in an unauthorized manner continue, the user of the base station terminal Y and the user of the unauthorized terminal Q are different, and the base station terminal Y When the location information P of the wireless communication terminal X that is frequently held illegally is referenced from an unauthorized terminal Q in an area different from a certain area, it is detected as being illegally used.
Thereby, in addition to the case where the wireless communication terminal X and the base station terminal Y that have been illegally held continue, the location information of the wireless communication terminal X that has been frequently illegally held by the unauthorized terminal Q Since the case where P is referenced is set as the detection condition, the accuracy of the determination of unauthorized use is further improved.

  As described above, as shown in FIG. 3B, the other person 5 carries the base station terminal Y (the base station terminal Y into which the unauthorized use detection program 200 has been introduced) constituting the unauthorized use detection system 100. In this case, the malicious person 4 does not browse the position information P such as the movement history even if the person is fooled without knowing the wireless communication terminal X held illegally.

(Unauthorized Use Suppression Program of the Present Invention)
Next, the algorithm of the unauthorized use detection program 200 introduced into the unauthorized use detection system 100 will be described with reference to FIG. In the following description, an example in which the unauthorized use detection program 200 is installed in the base station terminal Y is shown. However, the unauthorized use detection program 200 may be installed in the management server S, and the base station terminal Y and In order to share the processing in the algorithm of the unauthorized use detection program 200 to the base station terminal Y and the management server S, both the base station terminal H and the management server S A part corresponding to each process may be introduced.

FIG. 4 is a flowchart showing the algorithm of the unauthorized use detection program 200 of the present invention.
The unauthorized use detection program 200 is introduced into the base station terminal Y through, for example, downloading from the management server S through the Internet line together with the program of the location information notification system 10 or in addition to the program of the location information notification system 10. Is done.
(1) As shown in FIG. 4, the unauthorized use detection program 200 first sets the base station terminal Y to the wireless communication terminal information Ix having the wireless communication terminal identification information IDx from the unauthorized wireless communication terminal X.

(2) The base station terminal Y enters the wireless communication detection range A from the wireless communication terminal X held illegally (see FIG. 1 or 3), in other words, the other person 5 carries the base station terminal Y. When the wireless communication terminal X illegally held in the state of being held by another person 5 and the base station terminal Y receives the wireless communication terminal information Ix having the wireless communication terminal identification information IDx (Yes in S2), the base station The wireless communication terminal information Ix is stored in the memory of the station terminal H (S3).
(3) In the memory of the base station terminal Y, wireless communication detection information in which each of the wireless communication terminal identification information IDx, the base station identification information IDy, the position information P, and the wireless communication reception time t is associated is created (S4). The radio communication detection information may be transmitted to the management server S every time the base station terminal Y receives the radio communication terminal information Ix.
(4) Referring to the wireless communication detection information, the CPU T installed in the base station terminal Y calculates the duration T during which the combination of the wireless communication terminal identification information IDx and the base station identification information IDy continues (S5). ). That is, the CPU refers to the wireless communication detection information, for example, the time to when the combination of the wireless communication terminal identification information IDx and the base station identification information IDy is first detected, and the latest in the time zone in which the combination is continuous The difference (tc-to) from the time tc is calculated as the duration T. Note that the timer is activated at the time to when the combination of the wireless communication terminal identification information IDx and the base station identification information IDy is first detected, and the timer at the latest time tc in the time zone in which the combination is continuous. May be the duration T. Note that the wireless communication detection information including the wireless communication reception time t is transmitted from the base station terminal Y to the management server S, and the duration T is calculated by the CPU mounted on the management server S based on the transmitted wireless communication detection information. You may let them.
(5) A preset set time Tref (for example, 5 minutes) is compared with the duration T (S6).
(6) If the duration T is longer than the set time Tref (Yes in S6), the unauthorized use detection flag is turned on (S7).
In this way, the unauthorized use detection program 200 acts on the location information notification system 10 and the unauthorized use detection system 100 detects unauthorized use of the location information notification system 10.
(7) When the unauthorized use detection flag is ON, the unauthorized use detection system 100 refers to the combination of the specific wireless communication terminal identification information IDx and the specific base station identification information IDy causing the failure from the wireless communication detection information. Then, the function of browsing the movement history of the unauthorized wireless communication terminal X having the specific wireless communication terminal identification information IDx from the unauthorized terminal Q is stopped (S8). Thereby, unauthorized use of the position information notification system 10 can be suppressed.
When attempting to view the movement history of the unauthorized wireless communication terminal X having the specific wireless communication terminal identification information IDx from the unauthorized terminal Q (the browsing request is made from the unauthorized terminal Q to the management server S). The unauthorized use detection system 100 has the specific base station identification information IDy carried by the protected person 1 so that the protected person 1 or the malicious person 4 can recognize that the unauthorized use has been detected, or You may display a warning with respect to the monitor provided in the fraudulent terminal Q which has specific fraudulent terminal identification information IDq which the malicious person 4 carries. As a result, unauthorized use of the location information notification system 10 by a malicious person 4 who is afraid of discovering unauthorized use can be suppressed.
