Embodiment Construction

[0014] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0015] Based on the description of the background technology, it is not difficult to understand that in the prior art, the verification method for certificate information requires a specific registration device for verification, the verification efficiency is low, and the verification limit is high. The identity verification method only feeds back whether the user's name and certificate number are consistent, and cannot verify the identity of the certificate holder. The verification reliability is low, and the centralized query se...

Abstract

The invention provides an authentication method and system based on a block chain. The method comprises the following steps: a user node generates credential information and basic credential information; after signing, the user node sends a credential verification request to a verification device; The verification device verifies the validity of the signature, and if the verification passes, the user voice print information and the verification head image, as well as the verification basic information; The authentication device matches the authentication basic information with the certificatebasic information, If the matching is successful, the certificate image encrypted by the user's voiceprint key is decrypted according to the user's voiceprint information and a preset algorithm, so that each participating node determines whether the user node has successfully verified the certificate information, and if the matching is successful, the authentication success message is written intoa block and broadcast to a block chain network. Thus, the online authentication of the certificate information is realized, the authentication limitation is reduced, and the authentication efficiencyand security are improved on the basis of guaranteeing the authentication reliability.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a block chain-based identity verification method and system. Background technique [0002] At present, with the development of a legalized society, it has become mainstream to manage citizens through ID card and other certificate information. However, in related technologies, the authentication method for certificate information requires a specific registration device for authentication, and the authentication efficiency is low. Authentication restrictions are relatively high, and it is difficult to popularize it to the general public. For example, the current ID card verification is completed by offline ID card readers. Manufacturers authorized by relevant departments produce card readers, which are embedded with special security modules for verification. And it is only limited to the authorized unit to verify the identity card, and the general public cannot comp...
