Embodiment Construction

[0063] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0064] refer to figure 1 , the system of the present invention includes three modules based on location server, outsourced cloud server and user terminal. Among them: complete the initialization of the system based on the location server, provide registration for the user terminal and the outsourced cloud server, and distribute the key to the successfully registered user terminal and the outsourced cloud server, and encrypt the data resources owned by itself and send it to the outsourced cloud server; The outsourced cloud server receives and stores the encrypted data resource sent by the location-based server, receives the service request sent by the user terminal, and matches and calculates the query result on the encrypted data resource, and sends the query result to the user terminal; the user terminal sends the location-based service request Request to t...

Abstract

The invention discloses a system and a method for location based service-orientated user privacy protection, which mainly solve the problems of poor safety and low processing efficiency of the existing scheme. The system comprises a location based server, an outsourced cloud server and a user terminal, wherein the location based server is used for finishing system initialization, providing registration and secret key distribution for the user terminal and the outsourced cloud server; the outsourced cloud server is used for storing enciphered data resources, calculating for the user terminal to obtain the query result needed by a user and sending the query result to the user terminal; the user terminal is used for sending a service request to the outsourced cloud server, and decrypting the data information list returned by the outsourced cloud server to obtain the query result; the user terminal and the outsourced cloud server carry out bidirectional authentication in a service. The system and the method disclosed by the invention realize privacy protection for the location information of the user and data resources, increases the system efficiency, and can be used for providing safe and fast dinning, entertainment and travel information for the user in actual life.

Description

technical field [0001] The invention belongs to the technical field of information security, and specifically relates to a user privacy protection system and method, which can provide accurate and efficient location-based services for user terminals under the background of cloud computing, and realize effective privacy protection of data resources and user terminal location information . Background technique [0002] With the development of mobile Internet technology, location-based services can bring great convenience to life and have been used more and more by people. In the traditional location-based service system, the service provider stores massive data resources. When the user terminal needs location-based services, it sends a request to the service provider according to its own location parameters and demand parameters. The data resources stored by the service provider itself After searching on the Internet, the data that meets the requirements is returned to the us...
