Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the present invention designs a privacy protection method for social network data sensitive attributes, wherein the social network data structure includes several original network data nodes, each original network data node contains sensitive attributes, node degrees, and the original network data node The node degree represents the number of other original network data nodes that are connected with the original network data node, and the social network data structure contains at least two different node degrees; the social network data sensitive attribute privacy protection method is in Add new network data nodes to the social network data structure to form a new social network data structure; based on the principle of L-diversity, it includes the following steps:

[0023] Step 001. In...

Abstract

The invention relates to a sensitive property privacy protective method for social network data. Based on the L-diversity principle, a new network data node is increased in a social network data structure, association between the new network data node and a candidate network data node is established to achieve protection of network data. The method well overcomes the shortcoming in the prior art that huge influence is caused to the network data while the network data are protected. Compared with an existing protective method, the aim of privacy protection can be achieved under the condition that the smallest influence is caused to the usability of the network data in the social network data structure.

Description

technical field [0001] The invention relates to a privacy protection method for social network data sensitive attributes. Background technique [0002] With the vigorous development of Internet technology, online social network services and applications have become an integral part of our lives. This phenomenon produces a large amount of network data, which has great implications for marketing, disease transmission, and psychological research. However, since there may be a large amount of personal privacy information in network data, if no protection measures are taken, it will cause privacy leakage and other issues. Therefore, research on privacy protection in network data has become an emerging research hotspot in the field of privacy protection. [0003] Since domestic research on privacy protection in network data is still in its infancy, in the existing technology, on the basis of summarizing and describing foreign research progress, a method that can resist attackers ...
