Digital identity verification method, apparatus and system based on block chains

Abstract

The invention provides a digital identity verification method based on block chains. The method comprises the following steps: when an application party certificate generating instruction is received,obtaining a first random number, so that an application server generates an application party certificate by using the first random number; obtaining the application party certificate and a securityfactor, and verifying whether the application party certificate is effective according to a public key in an application party root certificate; if so, generating a wallet certificate by using the security factor; after an input password is received, obtaining a second random number, calculating a summary value according to the second random number and the password, and verifying whether the summary value is correct; and if so, singing transaction information and the security factor by using a private key in purse service, so that the application server verifies whether the wallet certificateis legal and effective by using the signature. By adoption of the random numbers, the signature and various certificates, high-security digital identity verification between block chains is achieved.The invention further provides a digital identity verification apparatus and system based on block chains, which have the above beneficial effects.

Description

technical field

[0001] This application relates to the field of electronic payment, in particular to a method, device and system for digital identity verification based on blockchain. Background technique

[0002] For now, digital currencies such as Bitcoin and Ethereum are issued, circulated, and traded on dedicated blockchains.
