Identity authentication method based on block chain network, server and terminal device

Abstract

The present invention discloses an identity authentication method based on a block chain network, a server and a terminal device. The objective of the invention is to perform identity authentication of nodes in the block chain network. The method comprises: receiving a registration request carrying user names sent by nodes; obtaining a first block chain account address associated with the user names according to the corresponding relation between the stored user names in advance and the first block chain account address; sending a transaction request carrying the first block chain account address and assigned second block chain account address in advance to the node to allow the nodes to construct a first transaction according to the transaction request and send the first transaction information to the block chain network after the first transaction is constructed, wherein the transaction request shows the operation of performing payment from the first block chain account address to the second block chain account address; determining whether the block chain has the first transaction information of performing payment from the first block chain account address to the second block chain account address or not; and if block chain has the first transaction information of performing payment from the first block chain account address to the second block chain account address, confirming the successful user identity authentication to improve the safety of the authentication.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to an identity authentication method, server, terminal equipment and system 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
