DETAILED DESCRIPTION In order to fully understand the present invention, its operational or functional advantages, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, the present invention will be described in detail by explaining preferred embodiments of the present invention with reference to the accompanying drawings. Like reference numerals in the drawings may refer to like elements.

1 is a configuration diagram of a location information sharing system 10 according to the present invention. Referring to FIG. 1, the location information sharing system 10 includes a service server 100, a push server 110, a token server 120, a location information server 130, a location sharer terminal 200, and a viewing user terminal. It consists of 300. Since the components of the location information sharing system 10 shown in FIG. 1 are not essential, the location information sharing system 10 may have more or fewer components.

The service server 100 is a core server that provides location-based services, and may generate or process information on its own, and not only the other servers 110, 120, and 130 for service provision, but also the location sharer terminal ( 200 and the viewing user terminal 300 may be controlled overall.

For example, the service server 100 generates a digital ticket having the authority to view the location information of the location sharer terminal 200 in response to a request from the location sharer terminal 200, and provides the digital ticket to the viewing user terminal 300. can do. The digital ticket may include a ticket token for the digital ticket, a device token for the location sharer terminal 200 and a Uniform Resource Locator (URL) for providing a location lookup function for the location sharer terminal 200. In this case, the URL may include ticket token information. The ticket token and the device token may be generated by the service server 100 or may be generated by the push server 110.

In addition, the validity period and the password may be set in the digital ticket. In this case, the service server 100 may match and store the ticket token and the device token. Of course, the service server 100 may store the expiration date and password set in the digital ticket together.

Meanwhile, the service server 100 may periodically change the password of the digital ticket and transmit the password to the reading user terminal 300. Then, the service server 100 may provide the location information service of the location sharer terminal 200 only when the changed password is received.

The push server 110 may provide a push to the location sharer terminal 200 in response to the push request of the service server 100. Then, the location sharer terminal 200 may generate / obtain various data or information necessary for the location information sharing method. For example, the location sharer terminal 200 may generate a one-time temporary token corresponding to the device token. In some cases, the temporary token may be generated by the service server 100 and the push server 110. However, when the temporary token is generated in the location sharer terminal 200, since the generation and storage of information are distributed, it may be more advantageous in terms of security.

Meanwhile, the location information sharing system 10 may not include the push server 110, and the push service may be performed by the service server 100. Of course, the location information sharing method according to the present invention may be made without using a push service.

The token server 120 may match and store the temporary token and the device token. The location information server 130 may store the temporary token by matching the location information of the location sharer terminal 200. On the other hand, the service server 100, the token server 120 and the location information server 130 may be provided in a physically separated location, it may be protected by an independent security system.

2 is a conceptual view illustrating that the servers 100, 120, and 130 are provided at physically separated locations in the location information sharing system 10 according to the present invention. Referring to FIG. 2, it can be seen that the servers 100, 120, and 130 are distributed on different continents. In order to obtain location information on the location sharer terminal 200, it is necessary to hack all of them and extract information obtained therefrom, which is very difficult in reality.

That is, according to the present invention, the token for the location sharer terminal 200 and the location sharer terminal 200 are stored separately in a plurality of servers, and the plurality of servers are physically separated and protected by an independent security system. Therefore, the possibility of leaking location information due to hacking in the location information sharing system 10 according to the present invention is extremely low.

The location sharer terminal 200 is a terminal of an owner who wants to share its location information, and the browsing user terminal 300 has authority to look up the location sharer terminal 200 through the location information sharing system 10. The terminal obtained the. The location sharer terminal 200 and the viewing user terminal 300 is preferably a mobile terminal having a wireless communication function, such as a smart phone, PDA, notebook.

The location sharer terminal 200 obtains location information, transmits the device token and the temporary token to the token server 120, and transmits the temporary token and location information to the location information server 130. The viewing user terminal 300 may display location information, which is the final result of the service, on a map.

When the service server 100 receives the digital ticket based location sharing request including ticket token information from the browsing user terminal 300, the service server 100 checks the device token corresponding to the ticket token information, and the checked The temporary token corresponding to the device token is checked from the ticket server 120. Then, the service server 100 obtains the location information corresponding to the confirmed temporary token from the location information server 130. That is, the service server 100 may only obtain simple location information that is not associated with the location sharer terminal 200.

Next, the service server 100 provides the acquired location information to the browsing user terminal 300 without being associated with the location sharer terminal 200 related information. That is, the browsing user terminal 300 may provide only simple location information. Therefore, even if the location information is leaked through the browsing user terminal 300, it is not possible to confirm whether the information is about the location sharer terminal 200 using only the leaked information from outside (ie, because it is anonymized information). Can be protected.

3 is a flowchart illustrating an example of a method of sharing location information of the location sharer terminal 200 according to the present invention. Hereinafter, the method of sharing the location sharer terminal 200 is performed with reference to Tables 1 to 3 showing examples of data stored in the servers of the location information sharing system 10 while the necessary drawings and the location information sharing method are performed. Look specifically at the process.

When the digital ticket generation request and the transmission request having the authority to share their location through the location sharer terminal 200 are received, the service server 100 generates the digital ticket and reads the digital ticket. 300) (S100). Of course, the generation and transmission of the digital ticket may be performed with a time difference.

The digital ticket related information may include a ticket token for the digital ticket, a device token for the location sharer terminal 200, and a URL for providing location information of the location sharer terminal 200. In some cases, the digital ticket related information may further include an expiration date or password of the digital ticket. The digital ticket may include URL information including ticket token information indicating the ticket token.

For example, the digital ticket may include a URL such as "http://mygo.com?ticket=T1235". "mygo.com" is an internet path for providing a location sharing service, and ticket = T1235 represents ticket token information corresponding to a digital ticket. The location sharing service may be provided by passing the ticket token information included in the digital ticket from the browsing user terminal 300 to the service server 100.

The service server 100 may control the location sharer terminal 200 to acquire and process information for a location sharing service through a push service using the push server 110 (S105). Meanwhile, since the service server 100 may directly control the location sharer terminal 200, this push service process may be an optional process.

When the digital ticket is generated, the service server 100 matches and stores the ticket token and the device token, and matches the temporary token generated corresponding to the device token with the device token to the token server 120. And store in, and matches the temporary token and the location information of the location sharer terminal 200 is stored in the location information server 130 (S110). Here, the temporary token may be generated by the service server 100, may be generated in the location sharer terminal 200, or may be generated in the push server 110. However, it may be advantageous for security to be generated in the location sharer terminal 200.

Table 1 is an example of digital ticket-related data stored in the service server 100, Table 2 is an example of matching information stored in the token server 120, Table 3 is stored in the location information server 130 It is an example of matching information.

Referring to Table 1, the service server 100 has a ticket token corresponding to a digital ticket (Ticket Token, Txxxx), a device token corresponding to the location sharer terminal 200 (Device Token, DEVxxxxxxxx), and a valid digital ticket. It can be seen that the period (Expire Time) is matched and stored.

Referring to Table 2, it can be seen that the device token for the location sharer terminal 200 and a temporary token corresponding thereto (One Time Device Token, OTDTXXXxxx) are matched and stored in the token server 120. The temporary token is a one-time token and may be changed periodically or aperiodically under the control of the service server 100. Through this, the security of the location information sharing system 10 according to the present invention can be further improved.

Referring to Table 3, it can be seen that the temporary information corresponding to the location sharer terminal 200 is stored in the location information server 130 by matching the location information and the time information. Meanwhile, the above-described information may be updated periodically or under the control of the service server 100 or at the request of the location sharer terminal 200 or the viewing user terminal 300.

As described above, in the location information sharing system 10 according to the present invention, hacking only one of a plurality of servers in which information is stored cannot obtain complete location information of the location sharer terminal 200. For example, even if the service server 100 and the token server 120 are hacked, location information cannot be obtained, and even if the token server 120 and the location server 130 are hacked, the location information is not found. I can't see who it is.

That is, externally, only the service server 100, the token server 120, and the location information server 130 need to be hacked to fully acquire the location information of the location sharer terminal 200, according to the present invention. The location information sharing system 10 may provide very high security.

In addition, since the servers 110, 120, and 130 are protected by an independent security system at physically separated locations, the server 110, 120, and 130 are illegally protected from the location information of the location sharer terminal 200 through the location information sharing system 10. It will be more difficult to obtain.

As described above, in the state where the digital ticket is generated and the information for the service is stored (S100 to S110), the position lookup (ie, the position) for the location sharer terminal 200 from the viewing user terminal 300 is performed. Information sharing) request is received (S120). In another embodiment of the present invention, acquisition and storage of location information for a service and generation and storage of related information may be performed after a location lookup request is received.

The request includes ticket token information indicating a ticket token for the digital ticket. If the password is set in the request, the information may also be included.

When the request is received (S120), the service server 100 determines the validity of the request, checks the stored device token matched with the ticket token information, and the confirmed device token from the token server 120 Check the temporary token corresponding to the, and obtains the location information corresponding to the confirmed temporary token from the location information server 130 (S130). Here, the validity of the request may be that the request is made within the validity period of the digital ticket, a password set in the digital ticket has been received, and the like.

Thereafter, the location information of the obtained location sharer terminal 200 is not associated with the location sharer terminal 200 related information (ie, as anonymous information) and provided to the browsing user terminal 300 (S130). ). Therefore, even when the location information is obtained externally in the process of performing the step S130, it is difficult to determine whose information is the location information.

In view of the above, on the assumption that the digital ticket-based location inquiry request corresponding to the ticket token "T1235" is received from the browsing user terminal 300, a detailed example of steps S100 and S140 will be described. see.

According to the request of the location sharing terminal 200, a digital ticket having the relevant information of the ticket token "T1235", the device token "DEV00010002, and the expiration date" May 28, 18 o'clock "is generated and transmitted to the reading user terminal 300. The transmitted digital ticket may include a URL including ticket token information indicating the ticket token, such as "http://mygo.com?ticket=T1235".

The digital ticket related information is stored in the service server 100, and the temporary token "OTDTXXX882" corresponding to the device token is matched and stored in the token server 120, and the temporary token and the location information server 130 are stored in the service server 100. The corresponding location information "Latitude 1200, Longitude 200" is matched and stored. The information storage in the token server 120 and the location information server 130 may be performed in real time through a push when a location inquiry request is received, or may be periodically updated through a push.

In this state, a location sharing request is received from the browsing user terminal 300 based on the selection for the digital ticket. Then, the service server 100 checks the ticket token information and the expiration date included in the request to confirm that the request is legitimate.

Then, the service server 100 checks the temporary token information "OTDTXXX882" corresponding to the device token "DEV00010002" matched with the ticket token at the token server 120, and checks the temporary token information "OTDTXXX882". Obtain the corresponding location information "Latitude 1200, Longitude 200". In this case, the obtained location information is obtained alone in a state that does not have an association with the location sharer terminal 200.

When the location information is obtained, the service server 100 may transmit only the acquired location information to the browsing user terminal 300, and display only the location information on the map on the browsing user terminal 300. At this time, the location information display process is not associated with any information related to the location sharer terminal 200. Therefore, the anonymity of the location information is guaranteed, so there is no possibility that the location information is leaked as personal information.

4 is an application main screen showing that a digital ticket is generated according to a method of sharing location information of the location sharer terminal 200 according to the present invention. 5 illustrates a digital ticket generation screen of an application that performs a method of sharing location information of the location sharer terminal 200 according to the present invention.

Referring to FIG. 4, it can be seen that a ticket can be generated by selecting a ticket making menu of the main screen of the application. The main screen may provide related information such as an expiration time of the digital ticket and the number of position lookups for the digital ticket. The horizontal bar graph at the bottom of the ticket may be an intuitive indication of the elapsed validity period of the digital ticket.

On the other hand, when the valid period set in the digital ticket expires, the service server 100 and the digital ticket stored in the service server 100, the token server 120 and the location information server 130 and You can delete related information. According to such a deletion method, when the validity period of the digital ticket expires, the leakage of the location information itself may be blocked.

Referring to FIG. 5, it can be seen that the digital ticket may include an issuer name, a ticket name, an expiration time, a password, and the like. "+ Destination" menu may be to give the digital ticket, in addition to the right to view the location information of the location sharer terminal 200, the share authority for the destination of the location sharer terminal 200.

If a destination sharing function is assigned to the digital ticket, the service server 100 matches the destination information of the location sharer terminal 200 with the temporary token and the location information of the location sharer terminal 200. Save to 130. Then, the digital ticket based sharing request is received from the viewing user terminal 300.

Then, the service server 100 obtains the destination information of the location sharer terminal 200 from the location information server 130 together with the location information, and transmits the destination information to the browsing user terminal 300. In this case, the destination information and the location information are transmitted in a state not related to the location sharer terminal 200 related information.

6A and 6B are screens illustrating examples in which the location information of the location sharer terminal 200 is provided according to the method of sharing the location information of the location sharer terminal 200 according to the present invention.

FIG. 6A illustrates that when a viewing user touches a digital ticket provided by a location sharer "Kim" in a terminal of the viewing user terminal 300, the viewing user terminal 300 includes a location of the location sharing terminal 200 (Present Location). ) And its destination are displayed together. The destination information is displayed on the browsing user terminal 300 because, as described above, a destination sharing authority is granted to the digital ticket.

The digital ticket requires execution of a dedicated application or access to a dedicated service site at the time of creation. However, since the digital ticket may function based on a URL for providing location information, a ticket such as a click / touch, etc. may be used without inquiring the above-described steps to inquire the location of the location sharer terminal 200 using the digital ticket. The choice is enough.

On the other hand, Location Related Contents are provided at the bottom of the screen of the browsing user terminal 300 illustrated in FIG. 6A. When the digital ticket-based location sharing request is received from the viewing user terminal 300, the service server 100 obtains contents related to the location of the location sharing terminal 200 and the reading user terminal 300. It may be to provide.

The content addition providing function may be a function added by the location sharer to the digital ticket when the digital ticket is generated. The related content may be traffic conditions (EX: congestion, traffic accidents, etc.), various news (EX: fire accidents, sex crimes, etc.), weather information (EX: heavy rain, heavy snow, etc.) associated with the location of the location sharer terminal 200, and the like. However, the scope of the present invention is not limited thereto.

6B illustrates that when the reading user touches the digital ticket provided by the location sharing unit “Kim” on the SMS application execution screen of the viewing user terminal 300, the viewing user terminal 300 uses the location sharing terminal 200 through a web browser. ) Indicates the location of the (Present Location) and its destination (Destination).

In this case, the reading user terminal 300 does not need to install a separate application for receiving a location sharing service, and does not need to subscribe to the reading user. This is because when the digital ticket received through the SMS application is selected, the location information of the location sharer terminal 200 may be provided through a web browser. Providing location information or a related service through a web browser may be equally applied to the examples of FIGS. 7 to 9.

Meanwhile, in FIG. 6A, the digital ticket is provided as an image, and the digital ticket of FIG. 6B is provided in a form representing a URL including ticket token information. These are only examples of the digital ticket providing method, and the present invention is not limited to the digital ticket providing method.

Provided to the browsing user terminal 300 (S210).

Then, the service server 100 checks whether the location information providing screen is switched from the browsing user terminal 300 or the related application is terminated (S220). When it is detected that the location information providing screen is switched or the related application is terminated in the browsing user terminal 300, the service server 100 deletes the location information of the location sharer terminal 200 from the location information server 130. If not (S230), otherwise maintains the location information storage state of the location sharer terminal 200 in the location information server (130).

The deletion of the location information of the location sharer terminal 200 may be blocked by the deletion. Meanwhile, in the example of FIG. 11, only the location information of the location sharer terminal 200 is deleted from the location information server 130. However, in another embodiment of the present invention, the service server 100, the token server 120, and the service server are deleted. Other information at 100 may also be deleted. Then, the security of the location information sharing system 10 according to the present invention can be higher.

12 is a flowchart illustrating still another example of a method of sharing location information of the location sharer terminal 200 according to the present invention. Hereinafter, the sharing method will be described with reference to necessary drawings.

The service server 100 periodically updates the information of the service server 100, the token server 120, and the location information server 130 at step S300. In the state where the above-described periodic update is performed, a location lookup request for the location sharer terminal 200 is received from the view user terminal 300 (S310).

Then, the service server 100 checks whether the remaining time until the next update exceeds the threshold time (S320). When the remaining time exceeds the threshold time, the service server 100 optionally updates the information stored in the service server 100, the token server 120, and the location information server 130. Next, in operation S330, a sharing service for the location information of the location sharer terminal 200 is provided based on the arbitrarily updated information in operation S340.

However, if the remaining time does not exceed the threshold time, the service server 100 provides a location information sharing service of the location sharer terminal 200 based on the latest regular update information (S350). According to the location information sharing method of FIG. 12, the real time of the location information providing service of the location sharer terminal 200 may be greatly improved.
