Abstract

The invention provides a decentralized privacy protection method. The method comprises: using a P2P network structure, constructing block chains by social platform regional server cluster nodes, storing user privacy data of a social platform in blocks in an encryption signature verification mode, and establishing an authorized access and safety protection mechanism of a distributed cluster database system. The invention provides a decentralized privacy protection method. The decentralized storage and authentication of user privacy data in a social network are realized. The authentication process is completed in the block chain, the validity of the user identity is ensured by utilizing the tamper resistance of the block chain, the data abstract is used for replacing a user personal information plaintext, information is matched for the user according to the data abstract, the user privacy information plaintext cannot be checked even if a malicious attacker intercepts the user information, and the privacy of the user is protected.

Description

technical field [0001] The invention relates to a social network, in particular to a decentralized privacy protection method. Background technique [0002] In recent years, social networks such as WeChat, forums, and Weibo have developed rapidly, and people usually join multiple social platforms at the same time to enjoy the convenience and complete services provided by the Internet. Taking two social platforms as an example, if a user who has already registered on one of the platforms wants to join another platform, he will send a request to the original platform to ask for the basic information of the user in order to provide personalized services. However, traditional identity authentication methods have issues such as user privacy disclosure, forged authentication information, and platform denial of authenticated behaviors. What's more serious is that the social network platform investigates a large amount of user-related information, and the user provides the system wi...
