Zero-knowledge proof and other block chain identity authentication and privacy protection core technology

Abstract

The invention discloses a zero-knowledge proof and other block chain identity authentication and privacy protection core technology. According to the technical scheme, the zero-knowledge proof and other block chain identity authentication and privacy protection core technology is characterized by comprising a login module, an authentication module, an information collection module, a privacy protection module, a control module and a data recovery module; the login module is used for a user to log in the system, and the user logs in an operation page to perform data operation after inputting identity information on a login page; the authentication module is used for verifying the identity information of the user, after the user inputs the identity information, the authentication module compares the input identity information with the identity information reserved by the system, if the comparison succeeds, login is allowed, and if an error occurs in the comparison, a login interface is closed; the information collection module is used for updating a verification password combination when a user logs in the system; the method has the advantages of high identity verification accuracy, efficient and safe authentication, safe and reliable login and high information data asset security.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and specifically relates to a block chain identity authentication such as zero-knowledge proof and core privacy protection technologies. Background technique [0002] Zero-knowledge proof was proposed by S.Goldwasser, S.Micali and C.Rackoff in the early 1980s. It refers to the ability of the prover to convince the verifier that a certain assertion is correct without providing any useful information to the verifier. A zero-knowledge proof is essentially an agreement involving two or more parties, that is, a series of steps that two or more parties need to take to complete a task. The prover proves to the verifier and makes him believe that he knows or has a certain message, but the proof process cannot leak any information about the proven message to the verifier. Numerous facts have proved that zero-knowledge proofs are very useful in cryptography. If zero-knowledge proofs can be used for...
