Embodiment 1

[0023] Decentralized Identifiers (DIDs for short) is a new type of verifiable and "self-sovereign" digital identity identifier. As a decentralized authentication data structure, it can define people, things and institutions , the method specification for decentralized identifiers was created by the World Wide Web Consortium (W3C). The emergence of blockchain technology provides opportunities for the implementation of decentralized identity management. In the form of shared trust nodes, each decentralized identifier is encrypted and protected by the private key of the identity owner. It is recognized that it can redefine the missing important security layer in the Internet protocol, that is, the identity layer. The traditional identity authentication management system is Centralized, while decentralized identifiers are completely independent of centralized management centers, third-party authentication services, and certificate authorities.

Abstract

The embodiment of the invention discloses a decentralized identifier management system based on an Ethereum block chain. The system comprises an intelligent contract on an Ethereum block chain and a decentralized identifier document analysis module under the block chain, a representation form of the distributed identifier is specified in the smart contract, an attribute analysis function of the decentralized identifier is realized through a decentralized identifier document analysis module; the user can use the public key which is publicly and autonomously used by the smart contract to realizekey alternation and management; the third-party service provider website and other users can verify the authenticity of the digital signature of the user under the block chain by inquiring the data in the decentralized identifier document so as to determine the user identity; and the entity can freely use any shared trust root to manage the decentralized identifier of the entity, so that the entity has no centralized authority and no single-point fault, and has high information management security and privacy.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, in particular to a decentralized identifier management system based on the Ethereum block chain. Background technique [0002] Digital identity refers to the public key that condenses the real identity information into digital codes, which can be queried and identified through the network and related equipment. With the continuous expansion of the Internet application field, the hidden dangers of network information security are becoming more and more serious. The technical means of resource access and usage rights are of great significance to ensure the security of the system and data and prevent hackers from stealing legitimate user information. Identity authentication technology has gradually become an important gateway to ensure network security. The traditional centralized identity identifier management system is based on centralized Authorities, such as corporate...
