Method used for continuously inquiring hiding user position based on mobile terminal in LBS (location based service)

Abstract

The invention relates to a method used for continuously inquiring hiding user position based on a mobile terminal in LBS (Location Based Service). The privacy protective result of the conventional method is not good. According to the method provided by the invention based on a virtual path program, phoniness inquiry data is carried in the sent reality inquiry data to conceal the track privacy of users. The method provided by the invention comprises the following steps of: firstly adopting a path planning strategy to select different path arrangement manners; secondly, selecting a transmit mode of phoniness information according to the inquiry information transmission mode; and finally inquiring information transmitting time and planning a strategy to solve the problem of space-time rationality of inquiry information, thereby better protecting the track privacy of users. The method provided by the invention uses a manner that the transmission reality inquiry is the adulteration phoniness inquiry, the reality track of the users is covered through constructing a phoniness path, and thus, the position track information of the users is protected; and the space-time rationality data transmission strategy is provided according to the possible attacker model, the phoniness path is more reasonably constructed, and the reality track is protected.

Description

technical field [0001] The invention belongs to the technical field of mobile Internet applications, in particular to a method for privacy protection of user movement tracks in privacy protection based on location services in the mobile Internet. Background technique [0002] With the rapid development of high-tech industries such as computer technology and communication technology, social productivity has developed rapidly and social production efficiency has been significantly improved. In recent years, the combination of Internet and mobile communication technology has provided mobile users with many value-added services, and location-based services (Location-Based Service, LBS) have begun to develop rapidly. LBS is a mobile information application service that provides services to users based on their location. For example, users can inquire about their nearest hospitals, restaurants, gas stations, etc., and can even inquire about menus, vegetable prices in specific res...

Problems solved by technology

The invention first adopts the path planning strategy to select different path layout methods (such as whether to intersect), and then selects the sending method of false messages (synchronous or asynchronous) according to the query message sending mode, and finally solves the time and space between query messages through the query message sending time planning strategy Rationality issues, complete protection of user trajectory privacy
