The information to be verified is related to both the user and the first proving party, that is, the first proving party stores the information to be verified, or has an encrypted value or a hashed value of the information to be verified, so that the first proving party can verify the information to be verified, and the information to be verified is used for judging whether the information to be verified is correct or not and whether signature verification is given or not.
In order to ensure the safety, reliability and no leakage of information, the user identity identifier and the information to be verified can be encrypted asymmetrically. The block chain system can quickly realize the verification process of the information to be verified, improve the verification rate and ensure the verification safety. After the information to be verified is verified to be correct by more than the set number N of first proving parties, the user can apply a trusted declaration of the information to be verified, such as a trusted declaration of a study certification, a trusted declaration of medical information, and the like, to the blockchain system, wherein the trusted declaration of the information to be verified includes signature information of the N first proving parties to ensure authority and public credibility of the trusted declaration, a hash value of the information to be verified, an object of the information to be verified representing the user to which the trusted declaration is directed, and a user identity identifier representing the user to which the trusted declaration is directed.

In order to ensure authenticity, reliability and good credit, the user identity identifier generation process includes user identity information, and if the information to be verified is just part or all of the identity information, the correctness of the information to be verified can be verified by acquiring the identity information hash value correspondingly included by the identity identifier on the chain. Therefore, the verification burden of the first proving party is reduced, and the reliability of passing the verification of the verification information is improved. The hash value of the identity information can be encrypted in a fragmentation mode or a block encryption mode, and when the information to be verified is only part of the content of the identity information, the result of correctness can be obtained by comparing the hash value encrypted in the block mode.
