  Hereinafter, a position information history verification system according to an embodiment of the present invention will be described with reference to the accompanying drawings. As a portable communication device to be used, a device that can acquire current position information and has a communication function to the Internet is assumed. Specifically, a general mobile phone, a multi-function mobile phone with a touch panel called a smartphone, and a tablet computer are included. Current position information acquisition methods include GPS (Global Positioning System), triangulation by a base station, Wi-Fi radio wave intensity, and combinations thereof.

  With reference to FIG. 1, the positional information history collation system of Example 1 is demonstrated. This system is operated by a location information history verification server 1 connected to the Internet. In addition, a user who desires to use this location information history collation system downloads a resident program from a server and installs it in a portable communication device to be carried.

  This resident program periodically measures the current position information and transmits it to the position information history verification server 1. In FIG. 1, only the user A who uses the mobile communication device 3A and the user B who uses the mobile communication device 3B are shown as representatives of the users of this location information history collation system. Assumes the presence of users.

  In the history database, as shown in FIG. 2, a history table 2 is provided for each mobile communication device. The history table 2 includes a serial number in which positioning data records are arranged in time series, a date and time when the recording was performed, a latitude and a longitude, a Cell-ID that identifies the base station 7 that is communicating at that time, It consists of the field of reception sensitivity.

  For identification of the user, a unique terminal ID assigned when the resident program is downloaded is used. That is, the history table 2 and the terminal ID have a one-to-one correspondence. When the resident program transmits the current position information to the position information history collation server 1, this terminal ID is simultaneously transmitted in addition to the Cell-ID and the reception sensitivity. Thus, instead of the ID assigned by the server, an individual identification number for identifying the mobile communication device itself may be used as the terminal ID.

  Specifically, using a GPS or the like based on a signal from the satellite 5, the resident program measures the current position every few minutes (for example, every 5 minutes) and specifies the latitude and longitude. Then, the measured longitude and latitude are transmitted to the position information history matching server 1 together with the Cell-ID, the reception sensitivity, the terminal ID, and the like.

  In the position information history verification server 1, the current position information of the mobile communication device specified by the terminal ID is recorded in the current position information table as shown in FIG. Each field of the current position information table corresponds to each field of the history table, but a terminal ID field for specifying the mobile communication device is provided instead of the time-series serial number.

  When receiving the current position information from the mobile communication device, the position information history matching server 1 checks whether or not the attached terminal ID is recorded in the current position information table. If not recorded, a new record is generated in the current position information table based on this current position information in correspondence with this terminal ID. Also, a history table of this terminal ID is generated.

  If already recorded, the previous current position information (latitude and longitude) is acquired from the record of the terminal ID and collated with the received current position information. If these latitude and longitude are substantially the same (for example, a difference of about 10 m at most), the received current position information is discarded without doing anything.

  When the current position information is different from the previous one, the recorded previous record is added as a new record to the history table corresponding to the terminal ID. Then, the record in the current position information table is updated with the received current position information, Cell-ID, reception sensitivity, and recording date / time. Therefore, in the history table, the stay time at the position indicated by a certain record corresponds to the time difference between the record and the subsequent record.

  For example, if the record following the record at time 13:30 is the record at time 14:30, it means that the user has stayed for one hour at the location of the first record. Cell-ID and reception sensitivity can be used as auxiliary data for reliability of longitude and latitude. The stay time at the position indicated by the newest record in the history table is the difference between the time of the corresponding record in the current position information table and the time at the position indicated by the newest record in the history table. The stay time at the current position is the difference between the time of the corresponding record in the current position information table and the current time.

  As another implementation mode, each record in the current position information table may be recorded as the latest record in the corresponding history table. That is, when updating each record in the current position information table, the latest update record is recorded as the latest record in the history table. In this case, the stay time can be calculated only from the history table.

  Next, according to an actual usage scenario, the function of the position information history collation system of this embodiment will be described. FIG. 4 shows the overall signal flow. For example, it is assumed that a user A who uses the mobile communication device 3A is drinking coffee in a cafe. If you want to talk to someone, pick up the mobile communication device 3A and click on the icon of the resident program. Normally, since the resident program is always executed (resident), the user search request is sent to the location information history collating server 1 instead of performing double activation. The current location information and the terminal ID are attached to the user search request.

  The location information history collation server 1 that has received this user search request searches the current location information table to identify the user of the mobile communication device located in the vicinity of the current location of the mobile communication device 3A. For example, a user in a range up to 50 m is specified. If the number of users in the range is a certain number of people, for example, 3 or less, users in the range up to 100 m are specified.

  Further, location information (hereinafter referred to as specific location information) of a place where the user stayed for one hour or more is extracted from the terminal ID history table of the mobile communication device 3A. Then, the specific position information is searched from the history table of the user in the above range. The retrieved records are displayed side by side in descending order of correlation with the history of the mobile communication device 3A. The rearrangement is performed by the following procedure, for example.

  First, the record of the user who stayed at the specific position at the same time as the mobile communication device 3A is given priority. Among them, the record that has stayed at the same time is given priority. Next, priority is given to the records of the user of the mobile communication device 3A and the user who has been in the same place and has a long accumulated stay time (not simultaneously).

  FIG. 5 shows an example of the record list screen displayed on the mobile communication device. Here, the top record with the highest priority is that the terminal ID is 415bfa41, and stayed for 4 hours and 25 minutes from 11:48 on August 28, 2011 in a place near Honmoku Citizen Park in Yokohama. Means. In addition, the date, time, and stay time when the mobile communication device 3A was in the place are shown in parentheses. Therefore, it can be seen that the user with the terminal ID 415bfa41 stayed together for 4 hours or more at the same place and at the same time.

  The name of the place is converted from longitude and latitude to an address by reverse geocoding, and the name is searched from the address using a telephone book service. However, when the phone book service cannot be used, such as a mountain or the sea, a notation such as “˜mountain” or “˜coast” is performed using a database in which longitude and latitude are associated with the name of the place. Since there is an error in GPS, the notation “˜near” is used.

  On the list screen, click on the place item (here, “Near Yokohama City Honmoku Citizen Park”), and Web search results using Yokohama City Honmoku City Park as the search term will be displayed. Here, the user of the mobile communication device 3A recalls that this is a record when he went to a jazz concert. When the terminal ID (here, “415bfa41”) is clicked, only the record of the user can be extracted as shown in FIG.

  Here, user A wants to talk to user B whose terminal ID is “415bfa41”. Therefore, when a message transmission button is clicked, a message editing screen is displayed (FIG. 7). When a message is input and the transmission button is clicked, this message is transmitted to the mobile communication device 3B having the terminal ID “415bfa41”. Specifically, the location information history verification server 1 first receives the message addressed to the mobile communication device 3B. Next, when the mobile communication device 3B transmits the current location information to the location information history verification server 1, the location information history verification server 1 returns a message addressed to the mobile communication device 3B.

  As shown in FIG. 8, this message displays the history data of the user A in addition to the message body. However, since the history data is displayed from a history highly relevant to the user B, the contents are the same as those in FIG. From this history data, user B can obtain certain information about what kind of person user A is. User B can reply to this message by clicking the reply button (FIG. 9). Moreover, the user A and the user B can repeat the exchange of messages as necessary. The message transmission / reception processing is performed by the resident program and the location information history verification server 1.

  This embodiment is the same as the first embodiment in that the resident program installed in the mobile communication device periodically measures the current position information. However, the positioning result here is stored in a database in the portable communication device. The structure of this database is the same as that of one history table in FIG. Since the recording method of the current position information is the same as that of the first embodiment except that the recording location is each portable communication device and the current position information table is not used, the details are omitted.

  That is, the resident program installed in the mobile communication device 3A in FIG. 1 stores the current position information obtained by GPS or the like in the memory of the mobile communication device 3A. The resident program installed in the mobile communication device 3B stores the current position information obtained by GPS in the memory of the mobile communication device 3B. Further, the resident program of the second embodiment has a position information history collation function similar to that of the first embodiment.

  Next, according to an actual usage scenario, the function of the position information history collation system of this embodiment will be described. FIG. 10 shows the overall signal flow. For example, it is assumed that the user A who uses the mobile communication device 3A is attending a party and first meets the user B who uses the mobile communication device 3B. User A makes a proposal to perform position information history collation. User B understands and exchanges the location information histories with each other by communication means such as Bluetooth.

  The mobile communication device 3A that has received the location information history of the mobile communication device 3B compares and collates with the location information history recorded in its own device, and extracts correlated records. And it arranges and displays from the thing with a high correlation. The method is the same as in the first embodiment, and the list shown in FIG. 6 can be used as the display example. The history comparison / collation processing is performed by a resident program of each mobile communication device. When the amount of position information history data is large, the verification target data may be only the latest data, not the entire history.

  Since the mobile communication device 3B that has received the position information history of the mobile communication device 3A also performs the same processing, the user A and the user B see the same display. And there is a possibility that the story bounces with each other as a clue. That is, the location information history extracted by the correlation can be a real-world ice breaker.

  The second embodiment is a desirable implementation in terms of security. That is, if the location information history information of the user is centrally managed in a location information history verification server, the reliability of the system is greatly impaired in the event of a leakage accident. However, in Example 2, it is limited to the risk of the trust relationship between user A and user B and self-responsibility.

  This embodiment is the same as the second embodiment in that the resident program installed in the mobile communication device periodically measures the current position information and stores it in a database in the mobile communication device. However, the location information history matching server extracts the correlation by comparing and matching the location information history.

  Examples of actual usage scenarios are as follows. FIG. 11 shows the overall signal flow. It is assumed that the user A who uses the mobile communication device 3A is present at the party and is the first meeting with the user B who uses the mobile communication device 3B. User A makes a suggestion that the position information history comparison is performed. The user B understands and receives the exchange request of the location information history from the mobile communication device 3A by Bluetooth at the mobile communication device 3B. At this time, the mobile communication device 3A and the mobile communication device 3B also receive each other's terminal ID.

  Next, the mobile communication device 3A and the mobile communication device 3B transmit the location information history stored in the mobile communication device to the location information history verification server. At that time, the terminal ID of the own machine and the terminal ID of the other party are also attached. The position information history collation server that has received these data extracts records having a correlation with the position information history. And it arranges and displays from the thing with a high correlation. The method is the same as that of the first embodiment, and FIG. 6 can be used as the display example.

  The function of the third embodiment viewed from the user is almost the same as that of the second embodiment, but the position information history is transmitted only to the position information history collating server and not transmitted to the partner terminal. Only data relating to common points is transmitted to the other party's terminal. Further, the position information history is not stored in the position information history check server. Therefore, even the first meeting can be used relatively easily. Also in this case, when the amount of the position information history data is large, the collation target data may be only the latest data instead of the entire history.

  In this embodiment, the position information history database of the first embodiment is used for information exchange between users. Specifically, I want to know the end time of the jazz concert on August 28, 2011. In that case, the function of the resident program is used. For example, when a user search button in FIG. 5 is clicked, a user search screen as shown in FIG. 12 is displayed.

  On the user search screen, place, date, time and stay time can be entered as search terms. For example, if you enter Yokohama City Honmoku Citizen Park, 2011/08/28 and click the search button, a search request is sent to the location information history matching server, and records of users who hit the search term are extracted. . For example, a user search result as shown in FIG. 13 is displayed. This search result is preferentially displayed from the search term closest to the input search term to the one with a long staying time.

  Here, when the item “415bfa41” which is the terminal ID is clicked, the screen is switched to a message editing screen as shown in FIG. When a message is input and the transmission button is clicked, the message is transmitted to the mobile communication device having the terminal ID “415bfa41”. In this way, a new means for obtaining information on a specific place and time is provided.

  As described above, according to the position information history collation system according to the present invention, by comparing and collating the position information histories between mobile communication devices, predetermined information relating to common points between users having the mobile communication devices is provided. I can. This makes it possible to expand options for new applications.
