Block chain identity authority management method based on distributed PKI

Abstract

The invention discloses a block chain identity authority management method based on a distributed PKI, and the method comprises the steps: firstly carrying out the identity authentication before a business platform is accessed; collecting a group of living body actions of a target user in a preset area range through a preset camera; comparing the image information of the living body action of thetarget user with stored face image information of a legal user; if it is detected that the image information of the living body action of the target user is not matched with the face image informationof the legal user, sending an alarm message including the image information of the living body action of the target user to an associated mobile terminal so as to remind a user of the mobile terminalto confirm whether the identity of the target user is legal or not; after the identity authentication succeeds, enabling the user to perform login verification on a login page of the service platform; adopting RSA asymmetric encryption (public and private keys) is adopted for a user name and a password input by a user to carry out data encryption and multiple verification. The safety of user identity authentication is greatly improved.

Description

technical field [0001] The invention relates to computer information processing and block chain technology, in particular to provide a distributed PKI-based block chain identity rights management method based on the system contract inside the block chain. Background technique [0002] Blockchain technology, blockchain refers to a technical solution for collectively maintaining a reliable database through decentralization and trustlessness. It is the underlying technology of digital currencies such as Bitcoin and Ethereum. In layman's terms, blockchain technology refers to a way for all people to participate in bookkeeping. The transaction confirmation on the blockchain is completed by the consensus of all nodes on the blockchain, and after the consensus is successful, it is packaged and written into the block. The blockchain maintains a public ledger for storing all transactions on the blockchain network. There is a database behind all the systems, and you can think of the ...

There is also little permission management in the existing blockchain. Generally, coarse-grained permissions are controlled by setting up user groups, etc., and the centralized PKI identity must be used to ensure security. It must rely on trusted third-party CAs to provide reliable services. However, in recent years, there have been issues such as core CAs spamming certificates and leaking relay root certificates.
