Identity authentication method, system and server based on blockchain network

Abstract

The invention discloses a method, a system, a server and terminal equipment for authenticating identities on the basis of block chain networks. The method, the system, the server and the terminal equipment are used for authenticating the identities for nodes in the block chain networks. The method includes receiving login requests with user names; acquiring first block chain account addresses according to preliminarily stored corresponding relations between the user names and the first block chain account addresses; judging whether first transaction of payment from the first block chain account addresses to preset second block chain account addresses is available in block chains or not; determining that the identities of users are successfully authenticated if the first transaction is available in the block chains. The login requests are transmitted by the nodes. The first block chain account addresses are associated with the user names. The method, the system, the server and the terminal equipment have the advantages that transaction information stored in the block chains cannot be tampered and can be traced back and queried, and accordingly the authentication safety and the credibility of authentication procedures can be improved; the users do not need to input passwords during login and do not need to remember the passwords, accordingly, the convenience can be improved, and database collision attack due to the fact that other malicious personnel log in other websites by the aid of stolen user names and passwords can be prevented.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to an identity authentication method, system, server and terminal equipment based on a block chain network. Background technique [0002] With the development of the Internet and e-commerce, computer network applications have penetrated into all walks of life, and global informatization has become a major trend in human development. Moreover, many websites or applications will require to log in to the website account before performing corresponding operations. For example, if a user wants to buy clothes on the XX website, the user is generally required to log in to the website with an existing account and then purchase. When a user logs in to a website or application, the identity of the user needs to be authenticated. There are many methods for identity authentication in the prior art, but most of the authentication methods use the user name and password to authenticat...

Problems solved by technology

[0003] However, in the prior art, there are situations where the server falsifies the authentication record or the authentication record stored in the server is tampered with, and the user name and password are easy to be stolen. Once the user name and password are stolen, the authentication can be passed, so this authentication The security of the method is not high
