Block chain identity construction and verification method

Abstract

The present invention relates to identity construction and verification on the Internet, and provides a block chain identity construction and verification method. The method comprises the following steps: a certificate authority constructs a user identity block chain according to an identity verification request submitted by a user; and the certificate authority performs user identity verification processing by means of the identity block chain. According to the method provided by the present invention, user identity information is written into the block chain, and multiple certificate authorities jointly complete confirmation and storage of the identity information by means of an agreement mechanism, and then the user can conveniently perform identity verification by using the block chain. The method is not only capable of improving efficiency of user identity verification, but also will not affect accuracy of the user identity information due to the problem of an individual certificate authority, thereby greatly improving security of an identity verification process.

Description

technical field [0001] The invention relates to identity construction and verification on the Internet, in particular to a block chain identity verification method. Background technique [0002] In real life, the government issues ID cards to verify the identity of residents. Similarly, users on the Internet also need to perform identity verification, but the verification is issued in the form of network data by the certification authority. The current Internet identity verification is highly dependent on the certification authority, and there are several problems as follows: [0003] (1) Since different certification agencies are relatively independent, users often need to perform operations such as registration, login, and verification in multiple certification agencies, which makes identity verification inefficient and inconvenient for users; [0004] (2) If the certification authority is attacked or there is malicious fraud, it will cause the user's identity informatio...

AI Technical Summary

Problems solved by technology

[0003] (1) Since different certification agencies are relatively independent, users often need to perform operations such as registration, login, and verification in multiple certification agencies, which makes identity verification inefficient and inconvenient for users;

[0004] (2) If the certification authority is attacked or there is malicious fraud, it will cause the user's identity information to be "stolen" or even "tampered with", directly threatening the safety of the user's property
