Problems solved by technology

The attacker may use the obtained information to spread malicious advertisements to users, to perform some malicious behavior against users, etc.
In other words, people's sensitive data is leaked, causing people's privacy and security to be compromised
[0004] In addition, in the prior art, the user's privacy requirements are mainly considered, and the user's Quality of Service (QoS for short) is less considered, and there is no clear definition

Embodiment Construction

[0016] In order to understand the present invention and its advantages more fully, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] First, refer to figure 1 , figure 1 A block diagram of the QoS-aware location privacy protection system according to the present invention is shown.

[0018] Such as figure 1 As shown, the system according to the present invention includes: a mobile object, an anonymous server, and a provider server.

[0019] The mobile object is used to make a location-based query request r and send it to the anonymous server.

[0020] The anonymous server is used to anonymously process the received query request r as r′=(pid, MBR(r.U out ), r.data). In addition, the anonymous server returns the query result obtained from the provider server to the mobile object.

[0021] The provider server is used to respond to the anonymously processed query request and return...

Abstract

The invention relates to a position privacy protection method for perceiving service quality, which comprises the steps that: A. a moving object puts forward an inquiry request r based on the position, and transmits the request to an anonymous server; B. the anonymous server disguisedly processes the inquiry request r into r'= (pid, MBR (r.Uout), r.data); and C. the anonymous server sends the disguisedly processed inquiry request to a provider server for inquiry, and returns the inquiry result obtained from the provider server to the moving object. By the invention, different privacy protection granularity and service quality can be obtained by selecting different privacy configuration parameters so as to easily find balance between the privacy protection requirement and the inquiry service quality.

Description

technical field [0001] The invention relates to the field of location services, in particular to a method for protecting location privacy based on perceived service quality. Background technique [0002] The development and combination of computing technology and wireless communication equipment makes it possible to obtain personal location anytime and anywhere, and at the same time promotes the emergence and development of a new type of application program - Location Based Service (LBS). Location service is a value-added service related to the user's current location. In recent years, people have begun to widely use various convenient and fast location-based services, such as location-related infotainment services, tracking and monitoring services for moving objects, information release such as commercial advertisements and promotional information, and emergency rescue services. [0003] However, while people are enjoying various location-based services, the privacy threat...
