Abstract

The invention relates to an anonymous registration method and system for protecting user privacy based on blockchain. This method involves the entity identity activation process and the anonymous account registration process: after the user's entity identity certificate is verified by an entity identity authentication agency, the commitment of the identity certificate information can be released to the block chain; after the user completes the entity identity activation , when registering anonymously on a website, zero-knowledge proof technology can be used to prove the legitimacy of one's own entity identity and the compliance of attributes. The invention can avoid leaking unnecessary private information of the user's identity certificate to the registration server during the registration process, and can make the registration server unable to obtain redundant identity private information while confirming that the user's identity attributes meet the requirements.
