Digital identity authentication method, equipment, device and system and storage medium

Abstract

The invention discloses a digital identity authentication method which is applied to a blockchain platform and comprises the following steps: responding to a digital identity information acquisition request sent by a user terminal, and sending a digital identity information ciphertext of a target user to the user terminal, so that the user terminal decrypts the digital identity information ciphertext to generate a digital identity information plaintext; responding to a digital identity information acquisition request sent by the verification terminal, and sending the digital identity information ciphertext of the target user and the security level to a verification terminal, so that the verification terminal judges whether the digital identity information ciphertext is matched with the digital identity information plaintext submitted by the user terminal or not, and if yes, performing security verification corresponding to the security level on the user terminal. The invention furtherdiscloses a digital identity authentication device, device and system and a computer readable storage medium. According to the invention, customized demands for various authentication modes can be met, and the security and reliability of digital identity authentication are improved.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a digital identity authentication method, device, device, system and computer-readable storage medium. Background technique [0002] With the development of information technology and network technology, digital identity verification has become a common scene in today's society. However, the digital identity verification in the prior art is generally relatively simple and single, and there is no distinction between verification scenarios of different importance, which are only provided by the verifier using the digital identity information provided by the approver who issues the digital identity and the user. The proof materials are compared and verified. Therefore, for some application scenarios that require a high level of security, such as banking business scenarios, the security reliability of the existing technology obviously needs to be improved. In view of t...
