Network identity authentication method and system based on block chain

Abstract

The invention discloses a network identity authentication method and a network identity authentication system based on a block chain. The method comprises the following steps: a user applies for a network identity ID with real identity information; data of a block chain system and a network identity ID issuer is synchronized; and when the user logins a website by using the network identity ID, authentication of the network identity is completed by using the network identity ID. According to the method and the system provided by the invention, the network identity ID is applied in advance and recorded in the network identity ID issuer, and the data in each node of the block chain system is synchronous with the network identity ID issuer, so that only authentication of the network identity ID is needed when the network identity is authenticating; as only the network identity ID needs to be provided, leakage of the real identity is avoided; due to the characteristics of the block chain, such as decentralization, dependability and tamper resistance, credit can be greatly improved; operation of the whole system can be ensured provided that part of the nodes in the block chain system still operate, so that operation stability is improved.

Description

technical field [0001] The present invention relates to the technical field of information security, and more specifically refers to a blockchain-based network identity verification method and system. Background technique [0002] Identity authentication, also known as "identity verification" or "identity authentication", refers to the process of confirming the identity of the operator in the computer and computer network system, so as to determine whether the user has access and use rights to certain resources, and then make the computer And network system access policies can be implemented reliably and effectively, preventing attackers from posing as legitimate users to gain access to resources, ensuring the security of systems and data, and the legitimate interests of authorized visitors. [0003] At present, the principle of network identity verification is to verify the identity by calling the open interface. However, it is easy to leak the real personal information of ...

Problems solved by technology

[0003] At present, the principle of network authentication is to verify the identity by calling the open interface. However, it is easy to leak the real personal information of the user, and anyone can freely obtain the real information data of a certain user through the interface. The credit is low and the operation is unstable.
