The invention provides an identity authentication method, device and system based on a block chain. The method includes: storing the user information and the second identity information in a block chain,; after ruser information and first identity information sent by a client is received, when identity authentication is carried out on a user, searching user information identical to the user information sent by the client in the block chain, obtaining second identity information corresponding to the user information after the same user information is searched, and performing identity authentication on the first identity information by utilizing the second identity information to obtain an identity authentication result. Since the blockchain performs data storage based on a distributed system and does not depend on centralized hardware to realize data storage, an illegal user is not easy to acquire stored data, and the security of identity authentication is improved.
Description
technical field [0001] The present application belongs to the technical field of identity authentication, and in particular relates to a block chain-based identity authentication method, device and system. Background technique [0002] In order to ensure the security of the system, the identity of the user is usually authenticated. Only the authenticated users have access and use rights to the system resources, preventing illegal users from pretending to be legitimate users, and ensuring the security of the system. [0003] In the prior art, the methods for authenticating the user's identity include: using a static password to authenticate the user's identity, using an electronic token, a short message dynamic password, etc. to authenticate the user's identity, but whether the static password is used to authenticate the user Whether to authenticate the identity of the user or to use electronic tokens and SMS dynamic passwords to authenticate the user's identity, there is a r...
