Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0039] The present invention provides an anonymous associated user matrix filling privacy dynamic release method, please refer to Figure 1-3 , including the following steps:

[0040] S1: During the system initialization phase, if the visitor wants to obtain the attribute set λ`=(λ 0, lambda 1, ......λ i ), i≤n is the network diagram established by the associated tags, then the visitor uploads the query requirements to the trusted processing center, and the trusted processing center will set the user associated network attribute configuration file MF according to the query requirements of the visitor, and the MF includes the access User attribute set λ`=(λ0 ,λ 1 ,...λ i ), i≤n, and query time span △t;

[0041] Among them, the visit...

Abstract

The invention belongs to the technical field of privacy leakage of mobile intelligent terminals, and particularly relates to an anonymous associated user matrix filling privacy dynamic publishing method. The system comprises the following operation steps: S1, in a system initialization stage, if a visitor wants to acquire a network diagram established by the associated tagsthat an attribute set lambda = (lambda 0, lambda 1,... lambda i) of all users in a certain mobile application service and is is less than or equal to n within a certain time period and the visitor uploads a query demand to a trusted processing center, and the trusted processing center sets a user associated network attribute configuration file MF according to the query demand of the visitor. The diversity is met, and the privacy protection requirement of the dynamic application service is met, so the real-time changing privacy of the user can be obtained in time, the privacy is dynamically released after being protected, and the continuously changing privacy relationship between the associated users can be reflected by constructing the user association network diagram.

Description

technical field [0001] The invention relates to the technical field of privacy leakage of mobile intelligent terminals, in particular to a method for dynamically publishing privacy by filling in an anonymous associated user matrix. Background technique [0002] At present, the privacy of associated users in mobile social application scenarios is dynamic and can undergo rapid and continuous changes in a short period of time. Timely acquisition and dynamic release of changing privacy cannot reflect the continuously changing privacy relationship between associated users. [0003] To this end, we propose an anonymous associated user matrix filling privacy dynamic publishing method. Contents of the invention [0004] In view of the above and / or problems existing in the existing method for filling the privacy dynamic release of the anonymous associated user matrix, the present invention is proposed. [0005] Therefore, the purpose of the present invention is to provide an anon...
