An anonymous query system for location service based on random agent and its using method

Abstract

The invention relates to a location service anonymous query system based on a random agent and its use method, which is characterized in that: it includes a user, an agent, a location service provider and a P2P network composed of agents; A location service request is issued, and the location service request is encrypted and forwarded to the target location service provider through a randomly selected proxy. The present invention also includes the use method of the location service anonymous query system based on random agents, comprising the following steps: 1) when the user enjoys the service, regularly connects to the P2P network composed of agents to update the agent information list; 2) the user regularly according to the situation of the P2P network Random start as a temporary agent; 3) The user randomly selects the agent; 4) The PKI encryption mechanism is used to encrypt the communication between the agent and the service provider. The present invention can be widely applied to protect the location privacy of users who are sensitive to location privacy, so that users can securely obtain location services.

Description

technical field [0001] The invention relates to a computer service information protection system and its usage method, in particular to a random agent-based location service anonymous query system and its usage method. Background technique [0002] In recent years, with the rapid development of the mobile Internet industry, various location-based service applications are also emerging. The location service provided by the location service provider allows users to obtain location-related services anytime and anywhere, which brings great convenience to people's life. But at the same time, there are endless incidents of service providers being attacked that lead to user information leakage, and location service providers are no exception, which threatens users' location privacy security to a certain extent. At present, there have been some research and design of location privacy protection systems, and the main problems are as follows: [0003] 1. Many methods use so-called t...

The central node itself also has security issues that may be caused by attacks.

[0005] 3. Many methods can achieve a certain degree of location privacy protection by confusing the user's precise location information into an area, but this requires the location service provider to make a major modification to the processing of the service request, so it is not flexible enough, which leads to location service providers Incentive to drive deployment is low
