Embodiment 2

[0098] Based on the above embodiments, before the digital identity verification, a registration process of the wallet service may also be included. see image 3 , image 3 Schematic diagram of the process of registering for the wallet service. The specific technical solution is as follows:

[0099] S201: The mobile terminal receives a user name and a login key set by the user, and applies for opening a wallet service;

[0100] This step may be that the user logs in to the mobile terminal, initiates an application for opening a wallet service on the selection interface of the mobile application, and sets a user name and a login key. After receiving the user's registration application, user name, login key and other information, the mobile terminal applies for opening the wallet service.

[0101] S202: The mobile terminal sends a check instruction to check whether the wallet service is personalized;

[0102] The mobile terminal sends a check command to the wallet service acc...

Embodiment 3

[0116] Based on the above-mentioned embodiments, the method of digital identity verification based on block chain may also include the process of wallet certificate update, see Figure 4 , Figure 4 It is a schematic diagram of the wallet certificate update process, and the technical solution is as follows;

[0117] S301: When the wallet public key certificate is updated, the mobile terminal checks whether the wallet service is personalized;

[0118] When the wallet public key certificate needs to be updated, the mobile terminal checks whether the wallet service has been personalized, because there is no need to update the wallet certificate without a personalized wallet service.

[0119] S302: If yes, the mobile terminal receives the second key pair generated by the wallet service, and sends a certificate update request to the wallet service issuer;

[0120] When the wallet service has been personalized, the wallet service will regenerate a key pair, that is, a public key a...

Embodiment 4

[0128] Based on the above embodiments, the blockchain-based digital identity verification system can also include a password update process, see Figure 5 , the picture and text are the flow chart of the password update provided by the embodiment of this application, and the technical solution is as follows:

[0129] S401: When the password is updated, the mobile terminal receives the password modification application and the input old password and new password;

[0130] When the password is updated, usually when changing the password for the user, the user first logs in the mobile application through the user name and login key, and selects the interface to submit the application for modifying the password. At this time, a corresponding dialog box can appear on the interface of the mobile terminal to prompt the user to enter the old password. and new password. After receiving the password modification application, old password and new password, the mobile terminal sends rele...

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. Digital currency wallets provide convenience for the use of various digital currencies. Users can choose different provider services according to their preferences, and establish, store, and maintain digital currency wallets by themselves. For example, if a customer initiates a payment service using Bitcoin, he needs to log in to the digital currency wallet, and only needs to enter the receiving account and amount, and the operation can be completed with simple operations. [0003] The core of the digital currency wallet is the user's ownership of the private key. Cold storage is usually used to store the wallet offline. Specifically, the user gene...
