Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a location-based information providing method,

The present invention relates to a location-based information providing method, and more particularly, to a location-based information providing method and apparatus for providing related information to a server when the location is reached.

BACKGROUND ART [0002] With the spread of mobile communication terminals incorporating GPS (Global Positioning System) receivers, location-based services are becoming more diversified. For example, various services are provided, such as providing local advertisements based on the location of a user, or providing local events (e.g., coupons, etc.) based on the location.

In order to determine the location of the user, a geo-fence technique has been developed in which a virtual fence is set and the position of the user is constantly monitored within the virtual fence.

However, there is a concern that the service providing technology based on geofence and other user locations may continuously violate the user's privacy by continuously collecting the location of the user. That is, in a situation where users can not recognize themselves, location information is continuously provided to the server, and operators use the location information of the user as big data. Further, when the big data is hacked, it may be exploited to track the user position.

Disclosure of Invention Technical Problem [8] The present invention has been proposed in order to solve such a conventional problem, and it is an object of the present invention to provide a location-based information providing method for protecting personal information of a user by reporting a gate ID to a server instead of a user's location information, The present invention has been made in view of the above problems.

Other objects and advantages of the present invention will become apparent from the following description, and it will be understood by those skilled in the art that the present invention is not limited thereto. It will also be readily apparent that the objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

According to an aspect of the present invention, there is provided a communication device including: a storage unit for storing gate information to which position information and a gate ID are mapped; And a control unit for checking the current position and the current position in the storage unit and transmitting the report including the gate ID to the server when the current position is included in the gate information .

The control unit may measure a vector value of the communication device and, when the vector value and the current position are included in the gate information, the vector value and the gate ID mapped to the current position may be confirmed in the storage unit .

The control unit may encrypt the report and transmit the encrypted report to the server.

The communication device may further include a GPS receiver that receives a satellite signal, and the control unit may analyze the satellite signal received through the GPS receiver to measure the current position.

According to a second aspect of the present invention, there is provided a method for providing information to a server based on a location in a communication device, comprising: measuring a location; Determining whether the measured position is included in the gate information stored in the communication device; Checking the gate ID corresponding to the position in the gate information if the position is included in the gate information; And transmitting the report including the confirmation gate ID to the server.

The present invention is advantageous in that the personal information of the user is protected by providing the central server with a report including the gate identification information based on the position and the vector value of the user without providing the GPS coordinates of the user to the server.

Further, the present invention determines whether the location information and the vector value match the mapping data included in the gate information in the mobile communication terminal, thereby preventing overloading of the central server and alleviating traffic between the communication terminal and the server There is an advantage.
