A zero-knowledge verification method based on blockchain

Abstract

The present invention provides a blockchain-based zero-knowledge verification method, comprising obtaining a receiving identifier from a provider by the blockchain, wherein the receiving identifier corresponds to the access of the blockchain authentication provider; the block The chain obtains a second identifier, the second identifier corresponding to the receiving identifier, the receiving identifier being different from the second identifier; the secure database containing the stored private identifiers is accessed by the blockchain, wherein the stored private identifiers are The private ID is the combination of the received identifier and the retrieved second identifier. Accessing a secure database containing the stored private ID by employing the blockchain, wherein the stored private ID is a combination of the received identifier and the retrieved second identifier, and wherein the secure database includes a The relevant data makes the password of the private ID have higher security performance.

Description

technical field [0001] The invention relates to the technical field of blockchain, in particular to a zero-knowledge verification method based on blockchain. Background technique [0002] The problem to be solved by zero-knowledge proofs is to prove to you that the assertion is true without revealing any information about the assertion. Take a monetary transaction as an example, trying to prove that the transaction is legitimate without telling you who the payer is, who the payee is, or how much. 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 CN108335106A discloses a blockchain-based zero-knowledge multi-ledger exchange and transfer method. In some scenarios, it is necessary to prove that the transfer transaction of multiple ledgers is within a legal exchange rate field set in advance, but a third party If the specific exchange rate cannot ...

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
