Identity association method based on block chain

Abstract

The invention discloses an identity association method based on a block chain. The method comprises the following steps: a client generates a first asymmetric key pair for a login user, generates an account address of the login user in the corresponding one or more blockchain networks according to a first public key in a first asymmetric key pair of the login user and a generation rule of one or more blockchain accounts on which the login user depends; the client generates a two-dimensional code, the mobile terminal scans the two-dimensional code provided by the client to obtain an associationrequest message contained in the association request message, and analyzes the association request message to obtain the login user name and the account address of the login user in the correspondingone or more blockchain networks; the the mobile terminal randomly generates a second asymmetric key pair by, and generates the account address of the mobile terminal in the corresponding one or moreblockchain networks. According to the invention, the technical problems of time and labor consumption, low efficiency and poor security caused by the fact that association needs to be manually realized at the server in the existing method can be solved.

Description

technical field [0001] The invention belongs to the technical field of blockchain and information security, and more specifically relates to a blockchain-based identity association method. Background technique [0002] Blockchain technology, also known as "distributed ledger technology", is a technical solution for decentralization and collective maintenance of distributed ledgers. Its essence is realized by the collective participation of multiple nodes through multi-party storage and multi-party computing. Distributed database system with untamperable data and credible calculation results. Blockchain is not a single technology, but the result of the integration of multiple technologies. Using blockchain technology to maintain a reliable and difficult-to-tamper ledger record can reduce the risk of trust and effectively reduce the risk of collaboration among participants. maintenance costs. [0003] The login method of existing operating systems (Windows, Linux, etc.) or b...

Problems solved by technology

[0005] Aiming at the above defects or improvement needs of the prior art, the present invention provides a block chain-based identity association method, the purpose of which is to solve the problem of the existing method of logging into the operating system or business system based on the mobile terminal due to the need The technical problems of time-consuming, labor-intensive, low efficiency, and poor security caused by manually implementing the association between the client and the mobile terminal, and the technical problems that the association process cannot be performed once the server fails
