Embodiment Construction

[0038] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0039] The purpose of the present invention is to provide a communication method between a client and a server for protecting geographic location privacy, so that any user of a geographic location information-based service can protect the user's geographic location privacy when using the service with a client. This method mainly improves the secret sharing scheme and key management algorithm.

[0040] The invention proposes a communication method between a client and a server for protecting geographic location privacy, which is suitable for Internet applications based on geographic location information services in mobile communication networks. The main steps of the method are as follows: the client using the geographic location information service utilizes the improved secret sharing scheme proposed by the...

Abstract

The invention relates to a client and server communication method capable of protecting geographic position privacy. The client communication method comprises the following steps: a client generates service request information according to user operation; the client decomposes the service request information into n service request information subdata; the client encrypts the n service request information subdata and sends the encrypted subdata to n relay mobile terminals selected randomly by the client respectively, wherein the ith encrypted service request information subdata is sent to the ith relay mobile terminal, and the i is an integer equal to or larger than 1 and smaller than or equal to n; and after decrypting the received service request information subdata, the relay mobile terminal sends the decryption result to a server. According to the client and server communication method capable of protecting geographic position privacy, the geographic position privacy of any user can be protected when the user, based on geographic position information service, utilizes the client to use the service; and the method is simple to operate and wide in application range.

Description

technical field [0001] The present invention relates to the communication field, in particular to information security, and specifically refers to a communication method between a client and a server for protecting geographical location privacy. Background technique [0002] In the Internet application technology based on geographic location services, when users use clients to request services from servers, they need to send their own geographic location information to the server. Based on geographic location service providers, mobile operators, and communication transmission centers Nodes will obtain all or part of the user's geographic location information and user identity information. Unauthorized collection, use and processing of this type of information will easily lead to the leakage of users' privacy information based on geographic location information services. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings...
