Description

  The present invention relates to a beacon signal generation system for a low power signal transmission terminal, which confirms that a person is near a business operator and allows only that person to acquire information from the business operator.

  In recent years, there are various position information utilization services using a short-distance wireless communication interface such as Wi-Fi (registered trademark) and Bluetooth (registered trademark) and a sound wave communication interface using a speaker / microphone interface. For example, in a service that uses Wi-Fi (Wireless Fidelity), a fixed code SSID (Service Set IDentifier) is transmitted from a wireless LAN base station (also referred to as an AP). Therefore, this is transmitted to a mobile terminal (smartphone, ipad). (Registered trademark)) and automatically or in some cases, the user selects a desired SSID from among multiple SSIDs received at the same location and receives a service associated with the SSID. is there.

  This system includes, for example, A system and B system.

(A method)
The method A is a method in which the wireless LAN base station 10, the router 20, and the server 30 are provided inside or outside the store so that the smartphone 50 receives the SSID, as shown in FIG. This server 30 may be installed in a data center via the connected Internet network.

  As a specific operation of the A method, a preset fixed SSID is periodically transmitted (within 50 m) from the wireless LAN base station 10, and the smartphone 50 receives and displays the SSID. Then, the user of the smartphone 50 selects the SSID displayed on the screen, connects to the server 30 via the wireless LAN base station 10 and the router 20, and receives the service content from the server 30.

(B method)
As shown in FIG. 47, in the B method, only the wireless LAN base station 10 is installed inside or outside the store, and the smartphone 50 is made to receive the SSID from this wireless LAN base station 10, and is automatically selected along with the selection of the SSID. In this method, the external store content providing server 70 provides the service content via the Internet network 60.

  The SSID of the store A is, for example, a 32-digit ASCII code "57AE ... E", and the SSID of the store B is, for example, a 32-digit alphanumeric "51C31 ... 8".

  On the other hand, the coupon ticket providing method of Patent Document 1 is disclosed as a service system using SSID.

  This coupon ticket providing method is for establishing wireless communication from a wireless terminal, which is also called a beacon station (AP) installed in a store, a road, or the like, to a wireless communication device, such as a smartphone, located in the vicinity. , The connection request signal (within 50 m) is transmitted periodically or continuously, and the mobile communication terminal receives the connection request signal.

  Then, the mobile communication terminal displays the SSID included in the connection request signal on the screen. It is disclosed that when the SSID is selected, the mobile communication terminal accesses the coupon providing server contracted by this store to receive the coupon ticket.

JP, 2014-178724, A

  Since the A method is a method in which the smartphone 50 communicates with the server 30 of the store via the wireless LAN base station 10 (AP), the store is provided only to the user who is close to the store (within 50 m) or is surely in the store. The service contents of can be provided.

  However, the A method requires a cable for connecting the router 20, the server 30, and the wireless LAN base station 10 (AP), etc., and therefore installation costs are high on the shop side.

  In the B system, the service content is directly obtained from the smartphone 50 that receives the SSID from the wireless LAN base station 10 (AP) and the external store content providing server 70 via the Internet network 60 based on the SSID. Therefore, there is no installation cost on the store side.

  However, in recent years, the personal computer itself can be used as a router, and the SSID information received by the smartphone can be copied and stored.

  Therefore, for example, a person who has a smartphone receives the SSID from the wireless LAN base station 10 (AP) near the store or in the store with the mobile communication terminal, saves the SSID, and returns home. Then, the home personal computer functions as a router, the SSID received by the router is transmitted to the smartphone, and the smartphone can access the store content providing server to obtain the service content.

  That is, the provision of service contents can be obtained by pretending to be located near the store or in the wireless LAN base station 10 (AP) in the store.

  On the other hand, the coupon ticket providing method of Patent Document 1 is disclosed as a service system using SSID.

  Since this coupon ticket providing method is the B method, the coupon ticket can be obtained from a remote home by using a personal computer.

  Generally, the shop side manages the number of issued coupon tickets, and when the customer comes to the shop with this coupon ticket, the accounting is discounted from the points described on the coupon ticket. Then, the actual sales amount of the store today is calculated from the number of used coupon tickets, the sales amount, and the issued coupon number of today.

  However, even if you are not actually near the store, you can get this coupon at a remote location, so use the coupon obtained at the remote location and add it to the coupon actually used in the store. Employees can cheat the actual sales because it is possible. Even in the case of giving store visit points instead of coupon tickets, even users can illegally acquire and accumulate points. Therefore, the coupon ticket service using the short-range wireless communication interface is not preferable from the management side.

  That is, even if an attempt is made to provide some information to an access from a person who passes near the business operator, in the conventional method, once the SSID is acquired near the business operator, the information can be provided even from a remote location. You can get it.

  The present invention has been made in order to solve the above-mentioned problems, has an inexpensive configuration, confirms that the person is near the business operator, and allows only that person to acquire the information from the business operator. The purpose is to obtain a method by which the service from the operator can be obtained.

  The AP-side timer 113 (program timer) immediately outputs the AP-side output signal Aouta to the AP-side calendar 112 along with the setting of the AP-side scramble SSID creation start time ATgi (for example, 10/20 10:00 on October 20, 2014). The AP side scramble SSID transmission interval ADi (30 sec) is measured in synchronization with the output of the AP side output signal Aouta, and the AP side output signal Aouta is again generated every time this AP side scramble SSID transmission interval ADi (30 sec) is reached. Is output to the AP side calendar 112.

  The AP side random number generator 114 generates a random number (one-time password: 16 digits, for example) with the AP side scramble SSID creation start time ATgi as an initial value in accordance with the output of the AP side scramble SSID creation start time ATgi from the AP side calendar 112. To generate. This random number is used as a decryption key for the scramble SSID. The AP side random number generator 114 is not always necessary.

  Then, every time the AP side scramble SSID generation time ASCTgi is output from the AP side calendar 112, the AP side random number generator 114 uses this AP side scramble SSID generation time ASCTgi as an initial value to generate a random number (one-time password: For example, 16 digits) are generated. This random number is used as a decryption key for the scrambled SSID.

  The AP side scramble SSID calculation unit 115 reads the AP side scramble SSID creation start time ATgi or the AP side scramble SSID generation time ASCTgi, and starts in synchronization with this. The AP-side scramble SSID creation start time ATgi or the AP-side scramble SSID creation time ASCTgi is collectively referred to as an AP-side scramble SSID creation time ATi.

  Then, the AP side scramble SSID creation time ATi (AP side start time ATgi or AP side scramble SSID generation time ASCTgi), the access point number APBi number of the AP side initial information AJi, and the AP side scramble SSID transmission interval ADi are set. The code string of the AP side ASCII code in the memory 117 is hashed by substituting it into a predetermined mathematical expression, and this is generated as an AP side random code (Aai).

  Then, the AP side scramble SSID (AAi) shown in FIG. 5 in which the management center name (GES) included in the AP side initial information AJi and the store code SPi are added to the AP side random code (Aai) is overwritten on the RAM 170. save.

The error time rti, the center side scramble SSID creation start time STgi, the version number BBi, the management center name (GEO), the center side scramble SSID transmission interval SDi, and the center side deletion time SNTi are included. In the present embodiment, since a plurality of access points may be installed in the store A, the registration center side initial information RSJi is registered for each store code SPi.

  The center-side first calendar 312 is activated according to the setting of the center-side scramble SSID creation start time STgi (for example, October 20, 2014, 10:00:00) from the center-side initial information setting unit 305. The center side scramble SSID creation start time STgi is set in the center side random number generator 314 and the center side scramble SSID calculation unit 315.

  The time SKgi is measured along with this activation (for example, October 20, 2014, 10:00:01, October 20, 2014, 10:00:02: ...: The center side first calendar as a whole. Measurement time SKKTgi). Then, every time the center-side output signal Souta (30 sec) is output from the center-side first timer 313, the center-side first calendar measurement time SKKTgi (for example, 2014 (Oct. 20, 10:00:30, Oct. 20, 2014, 10:00:00, ...), and extracts the center side scramble SSID generation time SSCTi (also called center side creation time) Is output to the center side random number generator 314 and the center side scramble SSID calculation unit 315 (also referred to as center side identification information creating means).

  However, when the center-side output signal Souta is output from the center-side first timer 313 for the first time, the center-side scramble SSID creation start time STgi (for example, October 20, 2014, 10:00:00) is output.

  The center-side first timer 313 starts when the center-side scramble SSID creation start time STgi and the scramble SSID transmission interval SDi (30 sec) are set from the center-side initial information setting unit 305.

  With this activation, the center-side first timer 313 outputs the center-side output signal Souta to the center-side first calendar 312, and thereafter, the center-side scramble SSID creation start time STgi (for example, October 20, 2014, 10 The time is measured from (00:00:00), and the center-side output signal Souta is output to the center-side first calendar 312 at every set scramble SSID transmission interval SDi (30 sec).

  The center-side random number generator 314 is activated each time the center-side scramble SSID creation time STi (STgi or SSCTi: collectively referred to as center-side creation time) is output from the center-side first calendar 312. Then, the center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID creation time SSCTi) is used as an initial value to generate a random number (one-time password: 16 digits, for example). The random number is used as a decryption key (for example, sd45 ... g) of the scramble SSID.

  The center side scramble SSID calculation unit 315 outputs the center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID generation time SSCTi) from the center side first calendar 312 (every 30 seconds). ) To start.

  When the center side scramble SSID calculation unit 315 is activated, the center side scramble SSID transmission interval (30 sec) included in the registered center side initial information RSJi from the center side initial information setting unit 305 and the access point number APBi. (Including a unique machine number), store code SPi, version number BBi (version of detailed content), management center name (for example, GEO), center side deletion time SNTi, allowable error time rti, etc. are read.

  Further, the center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID generation time SSCTgi) is read from the center side first calendar 312, and these are substituted into a predetermined mathematical expression to be stored in the memory 316. The code string of the center side ASCII code is hashed and generated as a center side random code (Sai) (see FIG. 9).

  The center side random code (Aai) includes the management center name (GES) included in the center side initial information SJi, the store code SPi, the version number BBi, and the center side scramble from the center side first calendar 312. The center side scramble SSID (SAi) shown in FIG. 9 to which the SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID generation time SSCTgi) is added is stored in the memory 395, and the center side second timer is also stored. For the creation unit 319 and the center-side scramble SSID hold unit 350, the center-side scramble SSID creation time STi (center-side scramble SSID creation start time STgi or center-side scramble SSS from the center-side first calendar 312) D generation time SSCTgi) and center side scramble SSID (SAi) and to the center-side second timer for generating an output signal Soutb output combining.

  At this time, the center-side scramble SSID calculation unit 315 reads the store code SPi and access point number APBi included in the registered center-side initial information RSJi every time the center-side scramble SSID (SAi) is generated, and reads them into these. The center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID generation time SSCtgi) from the center side first calendar 312 is associated with the generated center side scramble SSID (SAi), and The decryption key (for example, sd45 ... g) from the center side random number generator 314 is associated and stored in the log table 360 as the log information RJi as shown in FIG.

  The center-side second timer generation unit 319 outputs the center-side second timer generation output signal Soutb (STi, SAi) from the center-side scramble SSID calculation unit 315 every time the center-side second timer 318 (318 a, 318b ...) Is generated.

Every time the center-side second timer creation unit 319 generates the center-side second timer 318 (318a or 318b ...), the number of the center-side second timer 318 (318a or 318b .. A center side in which the center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID generation time SSCtgi) and the generated center side scramble SSID (SAi) are associated with each other. It is stored in the second timer table 319A (see FIG. 11).
This information is called center-side second timer information SrJi.

  Then, the center-side deletion time SNTi (5 minutes) from the center-side initial information setting unit 305 is set in the generated center-side second timer 318 (318a or 318b ...), and the center-side second timer generation output signal is set. The time from the center side scramble SSID creation time STi (STi, SSCTgi) included in Soutb is measured.

  The aforementioned center side second timer 318 (318a or 318b ...) Is a program timer, and measures the time with the setting of the center side scramble SSID creation time STi (STgi or SSCTgi), and this time ti is the center side. When the deletion time SNTi (5 minutes) is reached, the output signal Soutc with the center-side second timer number Sri is output to the center-side second timer creation unit 319.

  Then, every time the center-side second timer creation unit 319 receives the output signal Soutc, the center-side second timer information SrJi (Sri, STi having the center-side second timer number Sri added to the output signal Soutc. , SAi) is read from the center-side second timer table 319A and output to the center-side deleting unit 317.

  The center-side deleting unit 317 outputs the center-side second timer information SrJi (Sri, STi, STi, SAi, SrJi (Sri, STi, Sri, STi, Si, SAi) every time the center-side second timer information SrJi (Sri, STi, SAi) is output. The record of the record number Di having the center side scramble SSID (SAi) corresponding to the center side scramble SSID (SAi) included in SAi) is deleted from the memory 395, and the center side second timer information SrJi (Sri, STi). , SAi), the center-side second timer 318a or 318b or the like having the center-side second timer number Sri is deleted.

It is estimated that it will take about 5 minutes to access using the AP side scramble SSID (AAi) received by a person inside or near the store, and if it is longer than that, it will move to somewhere and somehow. This is because there is a possibility of unauthorized access, and is deleted as 5 minutes as an example.
Therefore, the memory 395 does not have to have a large capacity.

  Further, the center side deletion unit 317 outputs the center side scramble SSID (SAi) and the center side scramble SSID creation time STi (STgi or SSCTgi) to the center side scramble SSID hold unit 350.

  As shown in FIG. 12, the store information memory 380 includes a store code SPi, an access point number APBi, a store name (GEO), a simple content KCi, a version number BBi, and the like.

  The center-side communication control unit 320 receives the AP-side scramble SSID (AAi) from the smartphone 200 from the Internet network 60, adds the center-side reception time SUTi of the center-side second calendar 325, and stores it in the memory 335. The scramble SSID presence / absence determination unit 330 is activated.

  The scramble SSID presence / absence determining unit 330 reads the AP side scramble SSID (AAi) from the memory 335 and determines whether or not the center side scramble SSID (SAi) matching the AP side scramble SSID (AAi) exists in the memory 395. . If they do not exist, the AP-side scramble SSID (AAi) received by the scramble SSID position confirming unit 340, which will be described later, the center-side reception time SUTi, and the non-match flag IF (“0”) indicating “no match”. And the AP side scramble SSID temporary non-information ASNJi), and outputs the AP side scramble SSID temporary non-information ASNJi (AAi, SUTi, IF (“0”)) to the center side scramble SSID hold unit 350. . Then, after this, the center side scramble SSID hold with the match / no match flag IF of the AP side scramble SSID temporary nothing information ASNJi (AAi, SUTi, IF (“0”)) being “no match”. When output from the unit 350, the center side communication control unit 320 returns an error.

  After the AP side scramble SSID temporary non-existence information ASNJi (AAi, SUTi, IF (“0”)) is output, the AP side scramble SSID temporary non-existence information ASNJi (AAi, SUTi, IF (“0”)) is matched. When the non-existence flag IF is output in the state of “matching” (“1”), the reception flag UF is returned to the scramble SSID position confirmation unit 340.

  Further, if the center side scramble SSID (SAi) that matches the received AP side scramble SSID (AAi) exists in the memory 395, the scramble SSID presence / absence determination unit 330 sets the match / non-match flag IF to “match”. The reception time SUTi on the center side, the received scramble SSID (AAi) on the AP side, and the reception flag UF are set to (“1”) and the scrambled SSID is provided as scrambled SSID information ASJi (IF (“1”), SUTi, AAi). It outputs to the position confirmation unit 340.

  The center side scramble SSID hold unit 350 uses the center code from the center side scramble SSID calculation unit 315 to store the store code SPi from the center side initial information setting unit 305, the access point number APBi, and the allowable error time rti (for example, 1 minute ± 3 sec). The center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID creation time SSCTgi) and center side scramble SSID (SAi) included in the second side timer generation output signal Soutb. The set is stored in the memory 351 as access allowable error information rJi (SPi, APBi, rti, STi, SAi) (see FIG. 13). This is because the allowable error time rti may differ depending on the size and location of the store and the position of the access point AP.

  Also, each time the center side deleting unit 317 outputs a set of the center side scramble SSID (SAi) and the center side scramble SSID creation time STi (STgi or SSCTgi), this is sent to the center side scramble SSID creation information SMJi (SAi). , STi) are sequentially stored in the memory 352 (see FIG. 14).

  Then, each time the center side scramble SSID creation information SMJi (SAi, STi) from the center side deleting unit 317 is stored in the memory 352, a center side scramble SSID hold timer 353 (353a, 353b, ...) Is generated. , The center side scramble SSID hold timer 353 (353a or 353b, ...) Is activated to measure the time.

  The center-side scramble SSID hold timer 353 (353a, 353, ...) Has the center-side scramble SSID hold timer number SHri and the center-side scramble SSID hold timer 350 as shown in FIG. The SSID creation time STi and the center side scramble SSID (SAi) are stored in the memory 354 and managed as center side scramble SSID hold timer information SHJi.

  When any of the center side scramble SSID hold timers 353 (352a, 353b, ...) Has reached the permissible error time rti (for example, 1 minute ± 3 sec), the center side scramble SSID hold timer 353 ( 353a or 353b, ...), the center side scramble SSID of the memory 352 is deleted.

  That is, even after 5 minutes have elapsed, the hold is performed during the allowable error time rti (for example, 1 minute ± 3 seconds). This is because the user may select the AP-side scramble SSID immediately after the lapse of 5 minutes, and it is possible to handle the selection immediately after the lapse of 5 minutes.

  Further, the center-side scramble SSID hold unit 350 inputs the AP-side scramble SSID provisional non-existence information ASNJi (AAi, center-side reception time SUTi, match non-existence flag IF (“0”)) from the scramble SSID presence / absence determination unit 330. , The reference time SZTi of the center side reference timer 355 is read, and the AP side scramble SSID provisional non-existence information ASNJi (AAi, center side reception time SUTi, match non-existence flag IF (“0”) from the scramble SSID presence / absence determination unit 330) The time difference zti from the center reception time SUTi included in The above-mentioned reference time SZTi is the world standard time, Japan standard time, or the like.

  Then, the access permissible error information rJi having the AP-side scramble SSID (AAi) included in the AP-side scramble SSID temporary non-existence information ASNJi (AAi, center-side reception time SUTi, coincidence non-existence flag IF (“0”)) is set. It is allocated from the memory 351 and updated to a new allowable error time rti (hereinafter, allowable error time rti + 1) obtained by adding the obtained time difference zti to the allowable error time rti included in the access allowable error information rJi. That is, the time difference caused by this processing can be absorbed.

  The scramble SSID position confirmation unit 340 determines whether or not the AP side scramble SSID provisional non-existence information ASNJi (AAi, center side reception time SUTi, match / non-match flag IF) from the scramble SSID presence / absence determination unit 330 is input. , If the AP side scramble SSID temporary non-information ASNJi (AAi, SUTi, IF (“0”) is input, the same center side as the AP side scramble SSID (AAi) included in the AP side scramble SSID temporary non-information ASNJi It is determined whether SMJi having the scrambled SSID (SAi) is present in the memory 352.

  If it does not exist, the match / non-presence flag IF is returned to the scramble SSID presence / absence determination unit 330 with “none (“ 0 ”)”.

  If present, access allowable error information rJi (store code SPi, access code SPi of AP side scramble SSID (AAi) and access point number APBi included in AP side scramble SSID temporary non-existence information ASNJi) The point number APBi and the allowable error time rti) are read from the memory 351, and the difference rASTi between this allowable error time rti and the reception time SUTi included in the AP-side scramble SSID provisional non-existence information ASNJi is calculated. If it is within the error time rti, the scramble SSID presence / absence determination unit 330 sets the match / non-presence flag IF to “(1)” and outputs the flag. That is, it is determined that the user is located within 50 m, and the coincidence non-existence flag IF is changed to “Yes” (“1”). If the calculated difference rASt allowable error time rti is equal to or longer than the difference rASt allowable error time rti, the match / non-presence flag IF is returned to the scramble SSID presence / absence determination unit 330 without being (“0”).

  Then, the scramble SSID position confirmation section 340 assigns the log information RJi having the AP-side scramble SSID (AAi) included in this AP-side scramble SSID temporary non-information ASNJi from the log table 360, and does not match this log information RJi. The flag IF is present (“1”), the acceptance flag UF (0001, 0002 ...) From the scramble SSID presence / absence determination unit 330, and the center-side reception time SUTi included in the AP-side scramble SSID temporary non-existence information ASNJi. Is added (see FIG. 10).

  Then, the store code SPi added to the AP-side scramble SSID (AAi) included in the received AP-side scramble SSID temporary non-existence information ASNJi, the access point number APBi, and the version number BBi are included in the simple content transmission permission information. It is passed to the store name / simple content notification unit 370 as KCJi.

  The store name / simple content notification unit 370 reads the store code SPi and the version number BBi included in the AP-side scramble SSID (AAi) of the simple content transmission permission information KCJi from the scramble SSID position confirmation unit 340, and stores them. Assign information MJi. Then, the simplified content KCi included in the store information MJi is read from the store information memory 380, transmitted to the smartphone 200 by the center side communication control unit 320, and the transmission completion flag OKF is set from the center side communication control unit 320. Write in the log information Rj (see FIG. 10).

(Overall operation explanation)
16 to 18 are sequence diagrams illustrating the operation of the scramble SSID generation service system according to the first embodiment.

  As shown in FIG. 16, first, the smartphone 200 downloads the smartphone-side scramble SSID service application 210 from the server (not shown) of the content providing service center (d1).

  On the other hand, the person in charge of the management center operates the center side personal computer 300a in the management center, and as shown in FIG. 7, the access point number APBi (for example, Gt04) and the center side scramble SSID creation start time STgi (for example, 2014). October 20, 10:10:00), store code (eg 101Z), version number BBi (eg 001), management center name (eg GEO), center side scramble SSID transmission interval SDi (eg 30 sec) The center side initial information SJi including the center side deletion time SNTi (for example, 5 minutes) and the permissible error time rti (for example, 1 minute ± 3 seconds) is input to the scramble SSID management server 300 and the AP side scramble SSID (AAi). Center side scramble SSID (SAi) similar to To made (d2). That is, a different center-side scramble SSID (SAi) is generated every 30 seconds (see FIG. 9).

  Then, the center-side scramble SSID calculation unit 315 generates the center-side scramble SSID (SAi), and stores the store code SPi and the access point included in the registered center-side initial information RSJii from the center-side initial information setting unit 305. The number APBi is read, the center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID generation time SSCTgi) from the center side first calendar 312 is associated therewith, and the generated center side The scramble SSID (SAi) and the decryption key (for example, sd45 ... g) from the center side random number generator 314 are associated and stored in the log table 360 as log information RJi as shown in FIG. 10 (d3).

  Then, the center side second timer creation unit 319 and the center side deletion unit 317 delete the center side scramble SSID (SAi) and the like in the memory 395 (d4), and the center side scramble SSID (SAi) is used as the center side scramble SSID. The data is output to the hold unit 350 and stored in the memory 352 (d4a). That is, the center side scramble SSID (SAi) after 5 minutes has been copied to the memory 352.

  Generation of the center side scramble SSID (SAi) will be described in detail with reference to a flowchart.

  First, the processing of the center-side initial information setting unit 305 will be described.

  FIG. 19 is a flowchart for explaining the processing of the center side initial information setting unit 305 of the scramble SSID management server 300.

  As shown in FIG. 19, the center side initial information setting unit 305 displays the dialog box shown in FIG. 7 on the center side personal computer 300a, and the center side initial information SJi (access point number APBi, center side scramble SSID creation start time). STgi, store code SPi, version number BBi, management center name (GEO), center side scramble SSID transmission interval SDi, center side deletion time SNTi, allowable error time rti) are input (S1).

  Next, the registration center side initial information RSJi is registered in the memory 305a (S2).

  The center side scramble SSID creation start time STgi included in the registered center side initial information RSJi is set in the center side first calendar 312 and the center side first timer 313 (S3). Then, the center side deletion time SNTi (5 minutes) is set in the center side second calendar 325, and the permissible error time rti (1 minute ± 3 sec) is set in the center side scramble SSID hold section 350 (S4).

  Then, the center side initial information setting unit 305 sets the center side scramble SSID transmission interval SDi (30 sec) included in the registered center side initial information RSJi in the center side first timer 313 (S5).

  With this setting, the center side scramble SSID creation unit 310 performs the following processing.

  FIG. 20 is a flow chart for explaining the processing of the center side first calendar 312. As shown in FIG. 20, the center-side first calendar 312 sets the center-side scramble SSID creation start time STgi (for example, October 20, 2014, 10:00:00) from the center-side initial information setting unit 305. It is determined whether it has been done (S10).

  Along with this setting, the center side scramble SSID creation start time STgi is set in the center side random number generator 314 and the center side scramble SSID calculation section 315 (S10a).

  Then, the time SKgi is measured, for example, in seconds (S11). For example, October 20, 2014, 10:00:01, October 20, 2014, 10:00:02, ... (Center side first calendar measurement time SKKTgi) is measured.

  Then, it is determined whether or not the center side first timer 313 outputs the center side output signal Sauta (30 sec) (S12).

  When the center-side output signal Sauta (30 sec) is output, the center-side first calendar measurement time SKKTgi (for example, October 20, 2014 at 10:00:00) is closest to the output timing of the center-side output signal Souta (30 sec). 30 seconds, October 20, 2014, 10:01:00, ...) is read (S13).

  Next, this is output to the center side random number generator 314 and the center side scramble SSID calculation unit 315 as the center side scramble SSID generation time SSCTi (S14). Then, it is determined whether or not the process is finished, and if it is not finished, the process is returned to step S12 (S15).

  That is, as shown in FIG. 21, when the center-side first calendar 312 outputs the center-side output signal Sauta (30 sec), when October 1, 2014, 10:00:30 (SKKTg1) is closest, If this is the center side scramble SSID generation time SSCT1, and the center side output signal Sauta after the next 30 seconds has elapsed is 10:01:00 on October 20, 2014 (SKKTg2) is the closest, This is set as the center side scramble SSID generation time SSCT2.

Next, the processing of the center side first timer 313 will be described with reference to the flowchart of FIG.
As shown in FIG. 22, the center-side first timer 313 determines whether or not the center-side scramble SSID creation start time STgi and the scramble SSID transmission interval SDi (30 sec) from the center-side initial information setting unit 305 have been set ( S21).

  If it is determined that it has been set, the center side output signal Souta (every 30 seconds) is output to the center side first calendar 312 (S22).

  Next, the time is measured from the center side scramble SSID creation start time STgi (eg, October 20, 2014, 10:00:00) (S23), and the scramble SSID transmission interval SDi (30 sec) is set. It is determined whether or not (S24).

  When the measurement time reaches the scramble SSID transmission interval SDi (30 sec), the center-side output signal Souta is output again to the center-side first calendar 312 (S25).

  Then, it is determined whether or not the process is completed, and if not completed, the process returns to step S23 (S26).

  Next, the processing of the center side random number generator 314 will be described below with reference to the flowchart of FIG. As shown in FIG. 23, the center side random number generator 314 outputs the center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID generation time SSCTi) from the center side first calendar 312. It is determined whether it has been done (S31).

  When output, a random number (one-time password: 16 digits, for example) is generated with this center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID creation time SSCTi) as the initial value. S32).

  Next, it is determined whether or not the process is finished, and if it is not finished, the process returns to step S31 (S33). That is, the center-side random number generator 314 newly generates a random number each time the center-side scramble SSID creation time STi (center-side scramble SSID creation start time STgi or center-side scramble SSID generation time SSCTi) is set.

  Next, the processing of the center side scramble SSID calculation unit 315 will be described below with reference to FIG.

  The center side scramble SSID calculation unit 315 outputs the center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID generation time SSCTi) from the center side first calendar 312 and the center side random number generator 314. It is determined whether or not the decryption key (for example, sd45 ... g) has been set (S41). The center side scramble SSID generation time SSCTi is set every 30 seconds.

  When the center side scramble SSID creation time STi is set, the center side scramble SSID calculation unit 315 makes the access included in the registered center side initial information RSJi stored in the memory 305a of the center side initial information setting unit 305. Point number APBi (including unique machine number) Center side scramble SSID transmission interval SDi (30 sec), center side scramble SSID creation start time STgi, store code SPi, version number BBi (version of detailed content), management The center name (GEO), the center-side deletion time SNTi (5 minutes), the allowable error time rti (1 minute ± 3 sec), etc. are read (S42).

  Next, the set center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or center side scramble SSID creation time SSCTgi), and the access point number APBi included in the registered center side initial information RSJi, The center side scramble SSID transmission interval SDi (30 sec), the center side scramble SSID creation start time STgi, the center side deletion time SNTi (5 minutes) and the allowable error time rti (1 minute ± 3 seconds) are substituted into a predetermined mathematical expression. Then, the code string of the center side ASCII code in the memory 316 is hashed, and this is generated as a center side random code (Sai) (S43).

  Then, in this center side random code (Sai), the management center name (GES) included in the registered center side initial information RSJi, the store code SPi, the version number BBi, the access point number APBi, and the center side scramble. The center side scramble SSID (SAi) shown in FIG. 9 to which the SSID creation time STi (STgi or SSCTgi) is added is obtained and stored in the memory 395 (S44).

  Then, the center side second timer generation output signal Soutb obtained by combining the center side scramble SSID (SAi) with the center side scramble SSID creation time STi (STgi or SSCTgi) is output to the center side second timer generation unit 319 and the center side scramble SSID. The data is output to the hold unit 350 (S45).

  Next, the store code SPi included in the registered center side initial information RSJi, the access point number APBi (including the unique machine number), and the center side scramble SSID creation time STi (center side scramble SSID creation start time STgi or The center side scramble SSID generation time SSCTgi), the center side deletion time SNTi (5 minutes), the permissible error time rti (1 minute ± 3 sec), and the set decryption key (for example, sd45 ... g) are associated with each other. The log information RJi (see FIG. 10) is generated in the log table 360 (S46).

  Then, it is determined whether or not the process is completed, and if not completed, the process returns to step S41 (S47). That is, the center-side scramble SSID calculation unit 315 generates a center-side scramble SSID (SAi) every 30 seconds and obtains this log information RJi. The decryption key of the log information RJi is preferably used when decrypting and confirming the center side scramble SSID (SAi) when there is any illegality.

  With the generation of the center side scramble SSID (SAi), the center side second timer creation unit 319 and the center side deletion unit 317 perform the following processing.

  FIG. 25 is a flow chart for explaining the processing of the center side second timer creation unit 319.

  As shown in FIG. 25, the center-side second timer creation unit 319, the center-side second timer creation unit 319, the center-side second timer generation output signal Soutb (STi, SAi from the center-side scramble SSID calculation unit 315. ) Is output (S61).

  When it is determined that the center-side second timer generation output signal Soutb (STi, SAi) is output, the center-side second timer 318 (318a, 318b ...) Is generated in the RAM (not shown) (S62).

  Next, the center-side second timer creation unit 319 generates the center-side second timer number Sri (Sr1, Sr2 ...) Along with the generation of the center-side second timer 318 (318a or 318b ...), The center side second timer 318 (318a or 318b ...) Is assigned and the center side second timer number Sri (Sr1 or Sr2 ..) is generated with the center side scramble SSID creation time STi (STgi or SSCTgi). The center side second timer information SrJi including the center side scramble SSID (SAi) is generated (S63).

  Then, the center-side second timer information SrJi is stored as shown in FIG. 11 (center-side second timer table 319A) (S64).

  Then, the center side second timer 318 (318a or 318b ...) Is set with the center side deletion time SNTi (5 minutes) from the center side initial information setting unit 305 (S65), and the center side second timer is generated. The time ti from the center side scramble SSID creation time STi (STi, SSCTgi) included in the output signal Soutb for use is measured (S66).

  Then, the center-side second timer 318 (318a or 318b ...) Determines whether the measured time ti has reached the center-side deletion time SNTi (5 minutes) (S67).

  When it reaches, the center side second timer 318 (318a or 318b ...) Outputs the output signal Soutc with the center side second timer number Sri to the center side second timer creation unit 319 (S68).

  Then, every time the center-side second timer creation unit 319 receives the output signal Soutc, the center-side second timer information SrJi (Sri, STi having the center-side second timer number Sri added to the output signal Soutc. , SAi) is read from the center side second timer table 319A (S69) and is output to the center side deleting unit 317 (S70).

  Then, it is determined whether or not the process is finished, and if it is not finished, the process returns to step S61 (S71).

  FIG. 26 is a flow chart for explaining the processing of the center side deletion unit 317.

  As shown in FIG. 26, the center-side deleting unit 317 determines whether the center-side second timer creating unit 319 outputs the center-side second timer information SrJi (Sri, STi, SAi) (S73).

  When the center side second timer information SrJi (Sri, STi, SAi) is output, it corresponds to the center side scramble SSID (SAi) included in the center side second timer information SrJi (Sri, STi, SAi). The record with the record number Di having the center side scramble SSID (SAi) is deleted from the memory 395 (S74).

  Then, the center-side second timer 318a or 318b of the center-side second timer number Sri included in the center-side second timer information SrJi (Sri, STi, SAi) is assigned and deleted (S75).

  Then, it is determined whether or not it is finished, and if it is not finished, the process is returned to step S73 (S76).

  That is, the generated center-side scramble SSID (SAi) and the center-side second timer 318 (318a or 318b ...) Are deleted every time the center-side deletion time SNTi (for example, 5 minutes) elapses.

  Then, as shown in FIG. 16, the person in charge on the management center side operates the center side personal computer 300a in the management center to generate the access point number APBi (eg Gt04) and the AP side scramble SSID as shown in FIG. Start time ATgi (for example, 10/20 10:00 on October 20, 2014), store code SPi (for example, 101Z), version number BBi (for example, 001), management center name (for example, GEO), and AP side The AP side initial information AJi including the scramble SSD transmission interval ADi (for example, 30 sec) is input to the short range wireless LAN terminal 100 (AP) to generate the AP side scramble SSID (AAi) similar to the center side scramble SSID (SAi). (D5).

  In the case of this AP-side scramble SSID (AAi), the person in charge of the management center generates it without turning on the communication control unit starting switch 155. That is, the AP-side scramble SSID (AAi) is created but not transmitted.

  As shown in FIG. 27, this AP side scramble SSID (AAi) is, for example, 32 digits of "GEOSD ... XAD92101Z001", and "GEO" is a scramble SSID service code indicating that it is a scramble SSID service. The part of "SD ... XAD92" is the AP random code (Aai), "101Z" is the store code SPi, and "001" is the version number BBi.

  The process of generating the AP-side scramble SSID (AAi) of the short-range wireless LAN terminal 100 (AP) in this management center will be described with reference to the flowchart of FIG.

  FIG. 28 is a flowchart for explaining the process of the AP-side initial information setting unit 111 in the short-range wireless LAN terminal 100 (AP).

  As shown in FIG. 28, the AP-side initial information setting unit 111 of the AP has the access point number APBi (place and machine) shown in FIG. 4 input to a personal computer (not shown) via the interface unit 190 for setting various information. (Unique number), AP-side scramble SSID creation start time ATgi (for example, 10/20 10:00 on October 20, 2014), store code SPi, management center name (GEO), AP-side scramble SSID transmission interval ADi ( 30 sec), AP side initial information AJi such as version number BBi (version of detailed content) is read (S81).

  Then, the AP-side initial information setting unit 111 sets the AP-side scramble SSID creation start time ATgi of the AP-side initial information AJi (for example, October 20, 2014, 10:10:00) on the AP-side calendar 112 (S82). ).

  Further, the AP side initial information setting unit 111 sets the AP side scramble SSID transmission interval ADi (30 sec) in the AP side timer 113 (S83).

  Then, it is determined whether or not the process is completed, and if not completed, the process returns to step S71 (S84).

  FIG. 29 is a flow chart for explaining the processing of the AP side calendar 112.

  As shown in FIG. 29, whether or not the AP-side calendar 112 has set the AP-side scramble SSID creation start time ATgi (eg, October 20, 2014, 10:10:00) from the AP-side initial information setting unit 111. Is determined (S91).

  With this setting, the time (measurement time Akti) is measured in units of seconds (S92). For example, it is measured as 10:10:01 on October 20, 2014, 10:10:02 on October 20, 2014 (collectively referred to as AP-side calendar measurement time AKKTgi).

  Next, the AP-side calendar 112 determines whether or not the AP-side first timer 313 outputs the AP-side output signal Aouta (30 sec) (S93).

  When the AP-side output signal Aouta (30 sec) is output, the AP-side calendar measurement time AKKTgi closest to the output timing of the AP-side output signal Aouta (30 sec) (for example, October 20, 2014, 10:00:30) , 10:20:00, October 20, 2014, ...) is read (S94).

  Next, this is output to the AP side random number generator 114 and the AP side scramble SSID calculation unit 115 as the AP side scramble SSID generation time ASCTgi (S95). Then, it is determined whether or not the process is finished, and if it is not finished, the process returns to step S93.

  That is, as shown in FIG. 30, when the AP side output signal Aouta (30 sec) is output, the AP side calendar 112 is closest to 10:00 o'clock 30 seconds (AKKTg1) on October 20, 2014, When this is the AP-side scramble SSID generation time ASCT1, and when the AP-side output signal Aouta after the next 30 seconds has elapsed is 10:01:00 on October 20, 2014 (AKKTg2) is the closest, This is the AP-side scramble SSID generation time ASCT2.

  FIG. 31 is a flowchart for explaining the processing of the AP timer 113. As shown in FIG. 31, the AP side timer 113 determines whether or not the AP side scramble SSID creation start time ATgi and the AP side scramble SSID transmission interval ADi (30 sec) from the AP side initial information setting unit 111 are set ( S101).

  If it is determined that it has been set, the AP-side output signal Aouta is output to the AP-side calendar 112 (S102).

  Next, the time is measured from the AP-side scramble SSID creation start time ATgi (eg, October 20, 2014, 10:00:00) (S103), and the set AP-side scramble SSID transmission interval ADi (30 sec. ) Has been reached (S104).

  When the measured time reaches the AP-side scramble SSID transmission interval SDi (30 sec), the AP-side output signal Aouta is output to the AP-side calendar 112 again (S105). Then, it is determined whether or not the process is finished, and if it is not finished, the process returns to step S103 (S106).

  Next, the processing of the AP side random number generator 114 will be described below with reference to the flowchart of FIG. As shown in FIG. 32, the AP side random number generator 114 outputs the center side scramble SSID creation time ATi (center side scramble SSID creation start time ATgi or AP side scramble SSID generation time ASCTgi) from the AP side calendar 112. It is determined (S111).

  When output, a random number (one-time password: 16 digits, for example) is generated with this AP side scramble SSID creation time ATi (center side scramble SSID creation start time ATgi or center side scramble SSID generation time ASCTgi) as the initial value. S112).

  Next, it is determined whether or not the process is finished, and if it is not finished, the process returns to step S111 (S113). That is, the AP-side random number generator 114 newly generates a random number each time the AP-side scramble SSID creation time ATi (AP-side scramble ASID creation start time ATgi or AP-side scramble ASID generation time ASCTgi) is set.

  Next, the processing of the AP-side scramble SSID calculation unit 115 will be described below with reference to FIG.

  The AP-side scramble SSID calculation unit 115 decodes the AP-side scramble SSID creation time ATi (AP-side scramble SSID creation start time ATgi or AP-side scramble SSID generation time ASCTgi) from the AP-side calendar 112 and the AP-side random number generator 114. It is determined whether a key (for example, sd45 ... g) has been set (S121). The AP-side scramble SSID generation time ASCTgi is set every 30 seconds.

  When the AP side scramble SSID creation time ATi is set, the AP side scramble SSID calculation unit 115 determines that the access point number APBi (unique to the AP side initial information AJi set by the AP side initial information setting unit 111 is set). No.), AP-side scramble SSID transmission interval ADi (30 sec), AP-side scramble SSID creation start time ATgi, store code SPi, version number BBi (detailed content version), and management center name ( GEO) and the like are read (S122).

  Next, the set AP-side scramble SSID creation time ATi (ATgi or ASCTgi), the access point number APBi included in the AP-side initial information AJi, and the AP-side scramble SSID transmission interval ADi (30 sec) are set to a predetermined value. The ASCII code code string in the memory 117 is hashed by substituting it into the mathematical expression, and this is generated as an AP-side random code (Aai) (S123).

  Then, the management center name (GES) included in the AP side initial information AJi, the store code SPi, the version number BBi, and the access point number APBi are added to the AP side random code (Aai), The scramble SSID (AAi) on the AP side shown in FIG. 5 is obtained (S124). Then, this is stored in the RAM 170 (S125).

  Then, it is determined whether or not the process is completed, and if not completed, the process returns to step S121 (S126). That is, the AP-side scramble SSID calculation unit 115 obtains the same as the center-side scramble SSID (SAi) every 30 seconds.

  Then, as shown in FIG. 16, the short-range wireless LAN terminal 100 (AP) is shipped in this state (d6). The person in charge of the store A installs this short-range wireless LAN terminal 100 (AP) on a wall or the like (d7), and turns on the communication control unit starting switch 155 (d8).

  As a result, the AP-side scramble SSID (AAi) for every 30 sec is extracted from the RAM 170 from the short-range wireless LAN terminal 100 (AP) (d9) and is actually transmitted according to the wi-Fi standard (d10).

  Then, the smartphone 200 of the smartphone carrier within about 50 m from the store performs the wi-Fi setting, receives the AP-side scramble SSID (AAi), and stores it in the memory (d11).

  Then, as shown in FIG. 17, the smartphone 200 executes a smartphone-side scramble SSID service application 210 described below.

  The smartphone 200 compares the received current AP-side scramble SSID (AAi) with each previous AP-side scramble SSID (AAi-1) in the SSID list 220 on the screen to determine whether they are the same (d20). .

  If they are different, the previous scramble SSID (AAi-1) in the SSID list 220 of the screen that is the same as the current AP side scramble SSID (AAi) is deleted (d21), and the received current AP is received. The side scramble SSID (AAi) is displayed instead of the previous scramble SSID (AAi-1) (d22). For example, as shown in FIG. 34, it is assumed that the AP side scramble SSID (AAi) is displayed as “GEO ... XAD101Z001”.

  Next, the smartphone 200 determines whether the AP-side scramble SSID (AAi) in the SSID list 220 on the screen is selected (d23). In this case, it is assumed that the received AP-side scramble SSID (AAi) is selected.

  When selected, the smartphone 200 reads the selected AP-side scramble SSID (AAi), and displays the selected scramble SSID management server 300 linked to the scramble SSID service code in the AP-side scramble SSID (AAi). The URL is transmitted via the Internet 60 (d24).

  The IP address of the smartphone 200 is added to the AP-side scramble SSID (AAi) and transmitted.

  On the other hand, the center-side communication control unit 320 of the scramble SSID management server 300 establishes a session with the smartphone 200 and receives the AP-side scramble SSID (AAi) (d25).

  Then, the center side communication control unit 320 adds the received AP side scramble SSID (AAi) from the smartphone 200 to the center side reception time SUTi of the center side second calendar 325 (for example, 10:01:05 on October 20, 2014). ) Is added and stored in the memory 335 (d26).

  Next, the scramble SSID presence / absence determination unit 330 of the scramble SSID management server 300 determines whether the center side scramble SSID (SAi) matching the AP side scramble SSID (AAi) exists in the memory 395 (d30). That is, it is determined whether the selected AP-side scramble SSID (AAi) is within 5 minutes after the AP-side scramble SSID (AAi) is transmitted.

  If the center side scramble SSID (SAi) does not exist, it is judged whether it is within the allowable error time rti using the scramble SSID position confirmation section 340 and the center side scramble SSID hold section 350 (d31).

  If it is within the allowable error time rti, it is determined that the shop is still within 50 m of the store A (d32), and this log information RJi is stored in the log table 360 (d33).

  Then, immediately, the store name / simple content notification unit 370 reads the store information MJi from the store information memory 380, and the center side communication control unit 320 transmits the simple content KCi included in the store information MJi to the smartphone 200. (D34).

  The smartphone 200 receives this simple content KCi and displays it on the screen (d35). For example, the simple content KCi shown in FIG. 36 is displayed. As shown in FIG. 36, photographs, store names, service items, etc. are displayed. Therefore, the user of the smartphone 200 can know which store it belongs to.

  Then, when the simple content KCi on the screen is selected (d36), the smartphone 200 directly accesses the server of the URL code associated with the simple content KCi (d37) and receives the detailed content Ci from this server. (D38).

  On the other hand, when the center side scramble SSID (SAi) matching the AP side scramble SSID (AAi) exists in the memory 395, the process proceeds to d32 and it is determined that the store is located within 50 m of the A store (d40). If it is determined that it is not within the allowable error time rti, an error is returned (d41).

  The processes of the scramble SSID presence / absence determining unit 330, the scramble SSID position confirming unit 340, and the center side scramble SSID holding unit 350 will be described in detail with reference to a flowchart.

  FIG. 35 is a flowchart for explaining the process of the scramble SSID presence / absence determining unit 330.

  The scramble SSID presence / absence determining unit 330, when notified of the reception of the AP side scramble SSID (AAi) from the center side communication control unit 320, reads the AP side scramble SSID (AAi) from the memory 335 (S131).

  Then, it is determined whether or not the center side scramble SSID (SAi) matching the AP side scramble SSID (AAi) exists in the memory 395 (S132).

  If not present (N), the AP side scramble SSID (AAi) received by the scramble SSID position confirming unit 340, the center side reception time SUTi, and the non-match flag IF (“0”) indicating “no match”. ) And AP side scramble SSID temporary non-existence information ASNJi) and output (S133).

  Then, the AP side scramble SSID temporary non-existence information ASNJi (AAi, SUTi, IF (“0”)) is output to the center side scramble SSID hold unit 350 (S134).

  Then, after the AP side scramble SSID temporary non-information ASNJi (AAi, SUTi, IF (“0”)) is output, the AP side scramble SSID temporary non-information ASNJi (AAi, SUTi, IF (“0”)) is matched. It is determined whether the non-existence flag IF is output (S135).

  Next, it is determined whether or not the match / non-match flag IF is “no match” (“0”) or “presence (“ 1 ”)” (S136).

  When the match / non-match flag IF is “no match” (“0”), an error is returned to the smartphone 200 via the center-side communication control unit 320 (S137).

  Then, it is determined whether or not it is finished, and if it is not finished, the process is returned to step S131 (S138).

  When it is determined in step S136 that the match / non-match flag IF is “match” (“1”), the reception flag UF is output to the scramble SSID position confirmation unit 340, and the process proceeds to step S138 ( S139).

  Further, when it is determined in step S132 that the matching center-side scramble SSID (SAi) is present, the match / non-match flag IF is set to “match” (“1”), and the center-side reception time STUi and AP-side The set of the scramble SSID (AAi) and the acceptance flag UF is output to the scramble SSID position confirmation section 340 as scramble SSID presence information ASJi, and the process proceeds to step S138 (S140).

  FIG. 37 is a flow chart for explaining the processing of the center side scramble SSID hold section 350. In this description, it is assumed that the memory 351 has already stored the access allowable error information rJi (SPi, APBi, rti, STi, SAi) from the center-side deleting unit 317 (see FIG. 13).

  The center side scramble SSID hold unit 350 determines whether the center side scramble SSID creation information SMJi (SAi, STi) has been input from the center side deletion unit 317 (S141). When input, it is stored in the memory 352 (see FIG. 14) (S142).

  Then, a center side scramble SSID hold timer 353 (353a, 353b, ...) With respect to the center side scramble SSID creation information SMJi (SAi, STi) is generated in a RAM (not shown) (S143).

  The center side scramble SSID hold timer 353 (353a, 353, ...) Center side scramble SSID hold timer number SHri, the center side scramble SSID creation time STi, and the center side scramble SSID (SAi). Is stored in the memory 354 (see FIG. 15) as the center side scramble SSID hold timer information SHJi (S144).

  Next, the access permissible error information rJi having the center side scramble SSID (SAi) included in the center side scramble SSID hold timer information SHJi and the center side scramble SSID creation time STi is read from the memory 351 (S145).

  Then, the allowable error time rti (1 minute + 3 sec) included in the access allowable error information rJi is allocated to the generated center-side scramble SSID hold timer 353 (353a or 353b, ...) (S146).

  Then, the center side scramble SSID hold timer 353 (353a or 353b, ...) Is started to measure the time (S147).

  Next, it is determined whether the center side scramble SSID hold timer 353 (352a or 353b, ...) Has reached the permissible error time rti (for example, 1 minute ± 3 sec) (S148).

  When the allowable error time rti (for example, 1 minute ± 3 sec) is reached, the center side scramble of the center side scramble SSID hold timer 353 (353a or 353b, ...) Has the center side scramble SSID hold timer number SHri. The SSID hold timer information SHJi is read from the memory 354 (S149).

  Then, the record of the memory 352 that retains the scramble SSID (SAi) of the center side scramble SSID hold timer information SHJi is deleted, and the center side scramble SSID hold timer number 353 (353a or 353a of the center side scramble SSID hold timer number SHri or , 353b), the center side scramble SSID hold timer information SHJi having the center side scramble SSID hold timer number SHri is deleted from the memory 354, and the access allowable error information rJi read from the memory 351 is deleted ( S150).

  Then, it is determined whether or not the process is finished, and if it is not finished, the process returns to step S141 (S151).

  That is, even after 5 minutes have elapsed, the hold is performed during the allowable error time rti (for example, 1 minute ± 3 seconds). In this case, the user may select the AP-side scramble SSID immediately after 5 minutes have passed, and it is possible to handle the selection immediately after 5 minutes have passed.

  Further, the center side scramble SSID hold section 350 performs the processing shown in FIG.

  As shown in FIG. 38, the center side scramble SSID hold unit 350 receives from the scramble SSID presence / absence determination unit 330 the AP side scramble SSID temporary non-existence information ASNJi (AAi, center side reception time SUTi, match non-existence flag IF (“0”)). It is determined whether or not is input (S161).

  When input, the reference time SZTi of the center side reference timer 355 (preferably a hard timer) is read (S162).

  Next, the AP-side scramble SSID provisional non-existence information ASNJi (AAi, center-side reception time SUTi, coincidence non-existence flag IF (“0”)) from the scramble SSID presence / absence determining unit 330 and the center-side reception time SUTi are included. The time difference zti is calculated (S163).

Then, the access permissible error information rJi having the AP-side scramble SSID (AAi) included in the AP-side scramble SSID temporary non-existence information ASNJi (AAi, center-side reception time SUTi, coincidence non-existence flag IF (“0”)) is set. It is assigned from the memory 351 (S164).
Then, the allowable error time rti included in the access allowable error information rJi is added to the calculated time difference zti to update to a new allowable error time rti (hereinafter, allowable error time rti + 1) (S165). That is, the time difference caused by this processing can be absorbed.

  Then, it is determined whether or not the process is finished, and if it is not finished, the process returns to step S161 (S166).

  39 and 40 are flowcharts for explaining the process of the scramble SSID position confirmation section 340. As shown in FIG. 38, the scramble SSID position confirmation unit 340 receives the AP side scramble SSID temporary non-existence information ASNJi (AAi, center side reception time SUTi, match non-existence flag IF) or the acceptance flag UF from the scramble SSID presence / absence determination unit 330. It is determined whether or not is input (S171).

  When it is determined in step S171 that the AP side scramble SSID temporary non-existence information ASNJi (AAi, center side reception time SUTi, match non-existence flag IF) is input, the AP side scramble SSID temporary non-existence information ASNJi (AAi, center side reception time). It is determined whether or not the SMJi having the center side scramble SSID (SAi) similar to the AP side scramble SSID (AAi) included in the SUTi and the match / non-match flag IF exists in the memory 352 (S173).

  If present, access allowable error information rJi (store code SPi, access code SPi of AP side scramble SSID (AAi) and access point number APBi included in AP side scramble SSID temporary non-existence information ASNJi) The point number APBi and the allowable error time rti) are read from the memory 351 (S174).

  Then, the difference rASTi between the permissible error time rti (1 minute ± 3 sec) and the reception time SUTi included in the AP-side scramble SSID temporary non-existence information ASNJi is obtained (S175).

  Then, it is determined whether this difference rASTi is within the allowable error time rti (S176). If it is within the permissible error time rti, the scramble SSID presence / absence determination unit 330 sets the coincidence non-existence flag IF to “(1)” and outputs it (S177). That is, it is determined that the user is located within 50 m, and the coincidence non-existence flag IF is changed to “Yes” (“1”).

  Then, the scramble SSID position confirmation unit 340 assigns the log information RJi having the AP-side scramble SSID (AAi) included in this AP-side scramble SSID temporary non-information ASNJi from the log table 360 (S178).

  Then, as shown in FIG. 39, this log information RJi has a match non-existence flag IF (“1”), a reception flag UF (0001, 0002 ...) From the scramble SSID presence / absence determining unit 330, and this AP side. The center side reception time SUTi included in the scramble SSID temporary non-existence information ASNJi is added (see FIG. 10) (S179).

  Then, the store code SPi added to the AP-side scramble SSID (AAi) included in the received AP-side scramble SSID temporary non-existence information ASNJi, the access point number APBi, and the version number BBi are included in the simple content transmission permission information. It is passed to the store name / simple content notification unit 370 as KCJi (S180).

  Then, it is determined whether or not the process is completed, and if not completed, the process returns to step S171 (S181).

  In step S171 shown in FIG. 38, if the AP side scramble SSID temporary non-existence information ASNJi is not input, or if the difference rASti obtained in step S176 is equal to or less than the allowable error time rti, the scramble SSID presence / absence determination unit 330 does not match. The flag IF is not returned (“0”) and the process is returned to step S181 of FIG. 39 (S182).

The system as described above may be configured as a cloud system in which each unit is in charge of a server so that it can support a plurality of access points.
Further, the AP side scramble SSID (AAi) may be applied to the authentication confirmation in the electronic commerce.

In addition, a specific example of the format of the beacon signal for creating the AP-side scramble SSID (AAi) of the above embodiment will be described below.
FIG. 41 is an explanatory diagram of a format configuration of the ibeacon standard. 41 (a) shows the standard of company A, and FIG. 41 (b) shows the standard of company B.

  As shown in FIG. 41, since the UUID is fixed, either Major or Minor is randomized (AP side scramble SSID creation unit 110 (program)). These are preferably randomized, for example, by date and time (DD on the vertical axis YYYYYMMDDHHMMSS, horizontal axis HH). Moreover, you may randomize using things (for example, characters) other than the date. The randomization may be performed in units of one hour, minutes, or seconds. However, when AP side scramble SSID (AAi) is used for online commerce, etc., it is preferably about 2 minutes, 3 minutes, 5 minutes, ... 10 minutes.

  Also, Major and Minor or one of them may be changed by date and time (DD of vertical axis YYYYYMMDDHHMMSS, horizontal axis HH), and the other may be changed by using another.

  Further, such an AP-side scramble SSID may be created for one year, stored in the memory, and transmitted at regular intervals. When the AP-side scramble SSID is stored in advance in this way, the AP-side random number generator 114, the AP-side calendar 112, and the AP-side initial information setting unit 111 are unnecessary. The output of the AP-side timer 113 is an output in units of one hour.

For example, in the case of an AP-side scramble SSID that changes in units of one hour, the major portion does not show a table in which the vertical axis is the number of days and the horizontal axis is the time (hourly unit), as shown in FIG. Store in memory.
Also, as shown in FIG. 43, the Minor portion stores a table in which the vertical axis represents the number of days and the horizontal axis represents the time (hourly) in a memory (not shown).

  Then, every time the AP-side timer 113 outputs an output signal in units of one hour, the AP-side scramble SSID calculation unit 115 sequentially reads the numerical sequences of the Major portion and the Minor portion from the memory, and the AP side combining these The scrambled SSID is stored in the RAM 170 (also referred to as first terminal side storage means) and transmitted (beacon signal).

Of course, the server side of the center also has a similar table in a memory (not shown), receives the AP-side scramble SSID from the smartphone 200, and compares it with the time of the corresponding record.
The center side initial information setting unit 305, the center side first calendar 312, and the center side random number generator 314 are unnecessary.

  An output signal from the center-side first timer 313 is output to the center-side scramble SSID calculation unit 315 every hour, and the numerical sequence of the Major portion and the Minor portion of the memory corresponding to this time is sent to the center-side scramble SSID ( It is stored in the memory 395 as SAPi).

  Furthermore, an AP-side random number generator 114 and an AP-side timer 113 are provided, and every time an output signal is output from the AP-side timer 113 at regular intervals, a numerical sequence of the Major portion and the Minor portion of the memory or each of the numerical sequences. The AP-side scramble SSID that is randomly combined with a numerical value may be generated. Further, symbols and katakana may be included in the numerical value sequence of the Major portion and the Minor portion of the memory.

  In this case, the center side is also provided with the center side first timer 313 and the center side random number generator 314, and each time the output signal is output from the center side first timer 313 at regular intervals, the memory major The center side scramble SSID is generated by randomly combining the number part and the numerical value sequence of the minor part or each numerical value.

  FIG. 44 is an explanatory diagram of the EddyStone format standard of the C company. The NamespaceID and InstanceID shown in FIG. 44 correspond to UUID + Major + Minor in the ibeacon standard.

  Even in EddyStone, it is preferable to assign a fixed ID to NamespaceID as in the case of ibeacon, divide the 6 bytes of InstanceID into two, and assign a random ID between 0 and 335544341 to both or one by 3 bytes. (AP side scramble SSID creation unit 110).

  FIG. 45 is an explanatory diagram of a format of the IMES JAXA standard. Also in this case, similarly to the other standards described above, the settable 33 bits are set to 4 bytes + 1 bit, and 4 bytes are allocated to each 2 bytes in the same manner as Major and Minor.

Furthermore, in the case of using Wifi wireless, SSID can be set up to 32 bits in ESS-ID (SSID) with half-width numeric characters and symbols.
Also in this SSID, the number of digits may be separated and set as a fixed ID and a random ID in the first half and the second half.
Further, also in the ID code by ultrasonic waves, a random signal ID may be switched and assigned at a specific time.
In any of the standards, the AP-side scramble SSID (major and / or minor) acquired by the smartphone 200 that is the receiving terminal is transmitted to the center.

At this time, the fixed ID (unique ID of the beacon antenna) of the access point, which is the base station transmitting the AP-side scramble SSID, and the time are transmitted.
Since the center server can identify the operator by the fixed ID registered in advance, the AP side scramble SSID sent by each beacon station (access point) is inquired in the server at that time to determine whether it is the correct SSID. To do.

If the collation is OK, it is determined that the terminal is near the beacon station.
If a relay station is installed, the AP side scramble SSID can be received even at a remote location, but since the AP side scramble SSID changes in units of seconds or minutes, it is assumed that the AP side scramble SSID could be received. Also, fraud using this can be prevented.

  In the above embodiment, the communication network includes the mobile communication terminal, the server of the management center, the low power signal transmission terminal that is installed on the feature and transmits the beacon signal that reaches a short range, and the content providing server. However, the content providing server may be connected using the communication network of the mobile communication terminal. Further, the low power signal transmitting terminal that transmits the beacon signal may not be connected to the network.
