Problems solved by technology

[0003] Most of the current research on mobile user privacy protection assumes that users move in Euclidean space (free space), that is, the direction of motion is not subject to any constraints, but this assumption is not valid in real life

Embodiment Construction

[0025] At present, most of the studies on privacy protection of mobile users assume that users move in Euclidean space, that is, the direction of motion is not subject to any constraints, but this assumption is not valid in real life. Based on the above reasons, this patent considers how to protect the location privacy of mobile users in a real road network environment. We propose a method for location privacy protection, which can make the generated fake location more in line with people's living habits and not easily recognized by the attacker. Therefore, it is of great significance to implement this privacy protection technology based on the location of moving objects in road network space.

[0026] Main technical characterictic of the present invention is embodied in:

[0027] 1) The generated fake location is more confusing

[0028] Since the distribution of users on each road is different at different times, and even at the same time, the distribution of users on each ...

Abstract

The invention relates to a privacy protection method based on a location of a moving object in road network space. The method comprises the following steps: sending location search request information to an anonymous server by a user; utilizing anonymous algorithm to finish anonymity by the anonymous server; sending an search after completion of anonymity to a serve based on a location by the anonymous server; conducting a search processing according to an anonymous request by the serve based on the location; and sending back a concentratedly selected real location to the user from searching processing results by the anonymous serve. According to the method, a false location generated through initialization is more natural and real, and in line with living habits of people; the protection for the privacy of the user is realized in the process of moving; and protection degree for the privacy of the user is improved.

Description

technical field [0001] The invention relates to a method for privacy protection based on the location of mobile objects in road network space. Background technique [0002] With the development and popularization of various positioning technologies and wireless communication technologies, mobile users can conveniently use location based services (location based service, LBS) while obtaining their own location information anytime and anywhere. LBS requires mobile users to provide their own location information when making service requests to the location-based server. The server processes the location-based query proposed by the user according to the location information provided by the user and returns the query result to the mobile user. However, while enjoying the convenience brought by various location services, people should also consider the harm caused by location privacy leakage. For example, a user is looking for the nearest hospital. In most cases, the location-ba...
