Information processing method, terminal equipment, server and storage medium

Abstract

The embodiment of the invention discloses an information processing method, terminal equipment, a server and a storage medium. The method comprises the following steps: acquiring a real position of the terminal equipment; constructing k-1 false positions corresponding to the real position by adopting a first false position generation algorithm, and reconstructing at least one target false position which cannot be reached by adopting a second false position generation algorithm to obtain a reconstructed first anonymous block, wherein all positions in the reconstructed first anonymous block can be reached; generating a query request based on the reconstructed first anonymous block, the first identification information of the terminal device and the request content, and sending the query request to a server. Therefore, the real position of the user is hidden by constructing the anonymous block, and the unreachable false position is reconstructed by calculating the accessibility of the position, so that the credibility of the false position in the anonymous block is ensured, the user movement track is further prevented from being mined, and the safety of user data is enhanced.

Description

technical field [0001] The present application relates to wireless communication technology, and in particular to an information processing method, terminal equipment, server and storage medium. Background technique [0002] With the continuous development of mobile communication technology and the continuous popularization of smart terminal equipment, location-based services (Location Based Service, LBS) have been more and more widely used in the mobile Internet and the Internet of Things, providing people with convenient Serve. However, because Location-based Service Provider (LSP) requires users to provide their own location information and publish corresponding request content results to users, this has led to third parties being able to obtain users' personal location privacy through attacks, data mining, etc. risk of information leakage.

Problems solved by technology

However, because the Location-based Service Provider (LSP) requires the user to provide their own location information to the user to publish the corresponding request content results, this has led to third parties being able to obtain the user's personal location privacy through attacks, data mining, etc. risk of information leakage

[0003] Although the privacy processing of user location data in traditional technologies mainly adopts privacy protection technologies such as encryption and generalization, there is a lack of discovery and protection of the relationship between location data, and these time-series location data will also leak part of the user's location privacy. , its security threat to location privacy data needs to be paid attention to and protected accordingly
