Embodiment 1

[0035] The embodiment of the present invention proposes a decentralized identifier attribute management system based on the Ethereum block chain. The system includes a smart contract module on the Ethereum block chain and an attribute management server under the block chain.

[0036] The smart contract module is used for user registration and management of decentralized identifiers and public key information associated with decentralized identifiers. Ethereum is an open source public blockchain platform with smart contract functions. Smart contract is a computer protocol designed to spread, verify or execute contracts in an informatized way. Smart contracts allow Trusted transactions without third parties, which are traceable and irreversible. The private key of Ethereum is randomly generated by the specp256k1 elliptic curve algorithm, the public key can be obtained through the private key, and the Ethereum address is a derivative of the public key. In asymmetric encryption t...

Abstract

The embodiment of the invention discloses a decentralized identifier attribute management system based on an Ethereum block chain. The system comprises an intelligent contract module on an Ethereum block chain and an attribute management server under the block chain, the attribute management server comprises a database module, a user authentication module, an authority management module and a webservice module, the decentralized identifier of the user and the secret key thereof are managed through the intelligent contract module. The data storage cost of the block chain is relatively high; According to the embodiment of the invention, the attribute management server under the block chain is adopted to store and manage the entity attribute data bound with the decentralized identifier of the user; and autonomous management of corresponding attribute data is realized through an authentication mode of the asymmetrically encrypted request token, so that the safety and privacy of identity information are ensured while the cost is effectively reduced, and the autonomy and the control right of a user on digital identity management are maintained.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, in particular to a decentralized identifier attribute management system based on the Ethereum block chain. Background technique [0002] At present, the digital identity system establishes a digital identity file by storing the user's personal attribute data and binding it with a unique digital identifier. The control and autonomy of the identity are extremely dependent on the security of the system, and the privacy of identity information is easily compromised. Excessive amplification, and the interaction of different types of identity information requires additional technical solutions for each identity system, such as the establishment of a joint identity system, but it is essentially a union between various identity service parties, rather than independent and real-time control by users , did not achieve the effect of cost reduction, and could not avoid the existin...
