Block chain digital identity customizable generation method and device

Abstract

The invention can be applied to the technical field of block chains, and provides a block chain digital identity customizable generation method and device, and the method comprises the steps: carrying out the classified storage of pre-received user identity data; generating a voucher hash value of the user according to the customization requirement of the user and the classified and stored identity data by using a distributed file system; and uploading the voucher hash value, the public key of the user and the digital identity contract corresponding to the user to a block chain network. Based on the RFID technology, data information needed by digital identity generation in various mobile devices can be collected in real time, and the data information comprises personal identity biological recognition data, position information data, health data and the like; and the private key generated by the digital identity can be safely stored in the RFID tag of the mobile equipment by means of the data encryption and data storability of the RFID, so that the security and confidentiality of the private key are enhanced.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a method and device for generating customizable block chain digital identities. Background technique [0002] In the current society, digital identity is the foundation of the Internet of Things, and all individuals can be identified as digital identities. Digital identities are generated by data actively reported by different organizations and users. Generally, they are generated as certificates, public keys, and private keys. The traceability is realized through the blockchain. The certificate hash and public key are stored on the chain, and the certificate and private key are stored off the chain. And the private key is generally kept by the user himself. However, existing digital identity generation technologies have the following disadvantages: [0003] 1. Data collection issues: The generation of digital identities requires a lot of personal data. General...

Problems solved by technology

[0003] 1. Data collection issues: The generation of digital identities requires a lot of personal data. Generally, such data is either collected by the issuing authority, or actively reported and collected by users, and there is no real-time collection device;

[0004] 2. The problem of digital identity generation: the generation of digital identities is generated by users according to the needs of verification agencies. The content of identity certificates required by each verification agency is different, and the lack of customized devices makes the generation of digital identities unable to be flexibly generated;

[0005] 3. The problem of digital identity storage: the generation of digital identity includes certificates, public keys and private keys. The storage of private keys and certificates is generally kept by users themselves, or stored in a centralized manner, which has low security and is prone to misappropriation
