Embodiment

[0042] like figure 1 According to the present invention, a digital identity (DID) scheme that takes into account data privacy and availability through blockchain is provided, including: a DID generation and management module, a certificate module, and identityHub, which is an identity data aggregation storage module.

[0043] The DID generation and management module includes functions such as off-chain cryptographic identity generation, on-chain DID storage and management;

[0044] The certificate module includes a certificate issuer registration and management module, a certificate application and management module;

[0045] The identityHub module includes main functions such as plaintext encryption and authorized access;

[0046] The digital identity is generated and stored on the chain through the above DID generation and management module, but at this time the identity does not have any additional attributes, and various actual attributes can be given to users in the form...

Abstract

The invention provides a system and method for achieving data privacy and digital identity through a block chain, and the system comprises: a digital identity generation and management module which carries out the identity generation in a cryptography mode under the chain, and carries out the storage and management of the digital identity on the chain; a certificate module which is used for certificate issuing registration and management and certificate application and management; and an identity data aggregation storage module which is used for carrying out plaintext encryption and authorizedaccess. Various actual attributes are given to a user in the form of a digital certificate through the certificate module, and the user stores the obtained certificate in the identity data aggregation storage module in the form of ciphertext for subsequent actual application. According to the invention, the personal identity is mapped in the blockchain through the DID, various attributes are given to the identity in a certificate authentication mode, and meanwhile, the security during data disclosure is ensured by means of proxy re-encryption.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a system for realizing data privacy and digital identity through block chains. Background technique [0002] In the identity verification scenario, the identity verification process is often accompanied by the disclosure of specific identity information. For example, if you want to inform others of your real-name verification information, you must issue valid documents such as personal ID cards, which greatly affects the Privacy and Security of Personal Data. [0003] The current difficulties are: 1) the generation process of personal DID; 2) the application and issuance process of certificates; 3) how to solve the problem of selective disclosure of personal information data. [0004] Patent document CN108306887B (application number: CN201810111633.8) discloses a blockchain-based IoT security and data privacy protection system, including an IoT security engine corresponding...
