A secure communication method and system for group users in an anonymous social network environment

Abstract

The invention provides a secure communication method and system for group users in an anonymous social network environment, and the method comprises the following steps: storing original data releasedby users in a group in a data cache pool, and carrying out a communication data waiting process; carrying out randomization disturbance based on k-anonymity technology on data in the data cache poolwhen a designated condition is met; Selecting data from the disturbed data, and storing the data in a data output pool; And the data output pool publishes the data to all users in the group to complete safe anonymous communication among the users in the group. The scheme expands a privacy protection method based on k-anonymity technology and randomization disturbance. Therefore, the personal identity of the data publisher is prevented from being leaked along with the increase of the published message when the users in the group communicate with each other, and a brand-new mode is provided forensuring the privacy research of the users in the group while the safe communication of the users in the group in the anonymous online social network environment is realized.

Description

technical field [0001] The invention relates to social network communication, in particular to a method and system for secure communication of group users in an anonymous social network environment. Background technique [0002] Against the backdrop of the deepening of the Internet and informatization, the development of social networks represented by groups is changing the way people communicate. Social network has become the fastest growing part of the Internet industry, the most active technological innovation, and the largest value-added effect. [0003] A social network is a user-based communication platform through which all users can publish information and realize the sharing and exchange of information resources. The emergence of social networks has facilitated people's communication. In recent years, anonymous social networks represented by groups have gradually emerged. One of the basic goals of anonymous social networks is to separate communication messages from...

AI Technical Summary

Problems solved by technology

The privacy protection of groups in the existing anonymous social network environment mostly assumes that anonymity can well ensure that the user's identity information is not exposed, but does not take into account that when the communication data increases, the attacker can Under certain circumstances, the identity of the user is re-identified by aggregated communication data, thereby revealing the privacy of the user
