Zero-knowledge verification method based on block chain

Abstract

The invention provides a zero-knowledge verification method based on a block chain, wherein the method comprises the steps: acquiring a receiving identifier from a provider through the block chain, and enabling the receiving identifier to correspond to the access of a block chain authentication provider; acquiring a second identifier by the block chain, wherein the second identifier corresponds toa receiving identifier, and the receiving identifier is different from the second identifier; accessing a secure database containing the stored private identifier by the block chain, wherein the stored private ID is a combination of the received identifier and the retrieved second identifier. In the method, by accessing a security database containing stored private IDs by adopting a block chain,the stored private ID is a combination of such that the received identifier and the retrieved second identifier are combined, and the security database includes data relating thereto such that a password of the private ID has higher security performance.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a zero-knowledge verification method based on block chains. Background technique [0002] The problem to be solved by zero-knowledge proof is to prove to you that the assertion is correct without revealing any information about the assertion. Taking currency transactions as an example, it is trying to prove that the transaction is legal without telling you who the payer is, who the payee is, or the amount. Therefore, the application in the blockchain can protect the privacy of transactions and effectively protect the information security of traders. [0003] For example, the prior art of CN108335106A discloses a zero-knowledge multi-account book exchange transfer method based on blockchain. In some scenarios, it is necessary to prove that the transfer transaction of multiple account books is in a legal exchange rate domain set in advance but the third party In the case whe...

Problems solved by technology

[0003] For example, the prior art of CN108335106A discloses a zero-knowledge multi-account book exchange transfer method based on blockchain. In some scenarios, it is necessary to prove that the transfer transactions of multiple account books are in a legal exchange rate domain set in advance but the third party In the case where the specific exchange rate cannot be known, to realize the multi-book transfer operation, the existing privacy transaction encryption / decryption algorithm will not be able to realize the privacy transaction in the blockchain technology scenario

Let’s look at a registration and login system based on blockchain zero-knowledge proof disclosed in the prior art such as CN110581768A, which is based on the premise of collecting user personal information, and these personal information of users belong to the category of privacy, and users do not want to be identified by third parties. collection, as this will lead to information leakage, and these information leakage incidents occur frequently, causing great distress to users

The existing solutions are all through the user's mobile phone number and email address, but it is not the best solution in terms of security, which may easily lead to the leakage of the user's private information, and the user does not want to give out their private information

[0004] In order to solve the common problems in the field that personal privacy is not safe, transaction privacy is easily tampered with, etc., the present invention is made
