Problems solved by technology

[0008] The above three privacy protection methods can achieve a certain degree of privacy protection. Although pseudonymity and anonymity technology are very easy to implement and operate, but the anonymity effect is poor, and they are often cracked by data mining tools; It has a better anonymity effect, but sacrifices the quality of location service enjoyed by users; encryption technology is the best in protecting location privacy, but the implementation is more complicated and its efficiency is lower

Embodiment Construction

[0062] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0063] The main idea of ​​the present invention is based on the location K-anonymity model and the central server structure, and proposes an enhanced greedy anonymity algorithm, which increases the judgment of the quality model and the privacy model, so that the obtained anonymous circle can achieve a better location Privacy protection effect, but also to achieve high-quality location services.

[0064] refer to figure 1 , a preferred embodiment of a location anonymity method for continuous query of the present invention is proposed. The location anonymity method of continuous query includes the following steps:

[0065] Step S110, when an anonymous query is receiv...

Abstract

The invention discloses a position anonymity method for continuous query, which includes: when receiving an anonymous query, detecting each unexpired pending anonymous query in a pending anonymous query set; when the unexpired pending anonymous query satisfies the quality model, The query to be anonymous is inserted into the candidate anonymous set; when all the queries to be anonymous in the query to be anonymous set are detected, and the number of queries in the anonymous candidate set is greater than or equal to a preset degree of anonymity, the candidate is anonymized The collection forms an anonymous circle, and judges whether the anonymous circle satisfies the privacy model; when the anonymous circle satisfies the privacy model, adjust the center of the anonymous circle and return the anonymous circle. The invention also discloses a position anonymity method for continuous query and a privacy protection system. The invention improves the privacy protection of continuous query, and improves the location service quality and anonymity efficiency.

Description

technical field [0001] The invention relates to the field of location services, in particular to a location anonymity method and device for continuous query, and a privacy protection system. Background technique [0002] Today, when mobile communication, geographic information system (Geographic Information System, GIS) and mobile positioning technology (Global Position System, GPS) are highly developed, mobile location information service (Location-Based Services, LBS) is an important part of mobile communication value-added services. The first link has gradually become an indispensable part of people's life. Users can query all kinds of required information anytime and anywhere through portable mobile devices, such as mobile phones, PDAs, and Palms. [0003] Although mobile location services make our daily life more convenient, the threat of privacy leakage caused by location information leakage is also increasing. Suppose the user sends a query request to the location dat...
