Embodiment Construction

[0043] The purpose of the present invention is to propose a strategy for automatically setting privacy control to alleviate the privacy leakage problem caused by information sharing.

[0044] The invention divides the privacy control of the user into two parts: the privacy control of the attribute in the user's personal file and the privacy control of the content published by the user. According to the user information, the present invention provides default settings that can better protect privacy for the two types of privacy controls.

[0045] 1. Privacy control of attributes in user personal files.

[0046] For specific application platforms, two types of statistical methods are adopted according to the number of active users. If the platform already has enough active users, statistical analysis is performed on its users directly; otherwise, statistical analysis is performed with the help of user data of other large OSNs (such as Weibo, Twitter, etc.).

Abstract

The present invention proposes a privacy control automatic setting method and system for social networks, including: according to the visibility of each user attribute in the personal file of the user to be privacy control, counting the user's personal disclosure degree of the user to be privacy control; A set of privacy attributes composed of various privacy attributes, and the text information to be published by the user to be privacy controlled is obtained, and the text information is input to multiple classifiers, each classifier corresponds to a privacy attribute, and the text information output by the classifier belongs to the corresponding privacy attribute. The probability distribution on the value and the entropy of the normalized probability distribution are used to obtain the suitable publicity of the text information; according to the personal files and published content of the friends of the user to be privacy-controlled, the personal publicity of each friend of the user to be privacy-controlled is obtained ; According to the user's personal disclosure degree, suitable disclosure degree and friend's personal disclosure degree, measure the privacy sensitivity of the text information to each friend, and determine the disclosure range of the text information according to the privacy sensitivity.

Description

technical field [0001] The present invention relates to privacy protection of social network, in particular to a method and system for automatically setting privacy control according to user information. Background technique [0002] The rapid development of online social network (OSN) in recent years has promoted the communication between people and accelerated the dissemination of information. At the same time, as the interaction between users increases, inappropriate privacy settings will spread personal information to an unpredictable range, threatening personal privacy and causing many privacy-related issues.

In addition, when a user publishes in...
