User identity authentication method and device in network

Abstract

Provided by one or more embodiments of the present description are a method and device for user identity authentication in a network, which are applied to a block chain network comprising a plurality of authenticated user nodes and a user node to be authenticated, the method comprising: acquiring identity information to be authenticated of a user node to be authenticated; sending a set of identity reference information related to the user node to be authenticated, wherein the set of identity reference information comprises the identity information to be authenticated and identity comparison information generated on the basis of the identity information to be authenticated; acquiring a determination result put forth by an authenticated user node on the basis of the set of identity reference information, wherein the identity information of the authenticated user node is at least partially the same as the identity information to be authenticated; and determining whether the identity information to be authenticated passes the authentication of the authenticated node according to the comparison relationship between the determination result and the identity information to be authenticated.

Description

Technical field [0001] This specification relates to the field of network information processing technology, and in particular to a method and device for user identity authentication in a network. Background technique [0002] The existing network platform usually adopts the B To C (organization to individual) model for user identity authentication, that is, the personal identity information submitted by the user is audited and authenticated by an organization with identity authentication qualification, and the authentication validity is based on business requirements. Different, the above-mentioned organizations with identity authentication qualifications may include CA organizations, organizations with high credit, such as banks, large state-owned enterprises, and network platform operators. The existing B To C certification model adopts a centralized certification method, which leads to the absolute power of the certification organization on the B side, which often amplifies t...

AI Technical Summary

Problems solved by technology

The existing B To C authentication mode adopts a centralized authentication method, which leads to the absolute power of the B-side of the certification organization, which often enlarges the demand and asks users for unnecessary information; and in terms of authentication efficiency, because each C-side user Each certification needs to submit government or third-party certificates, and then the B-side of the certification organization will review them one by one. Limited by the number of platform reviewers, this type of certification is relatively inefficient
