According to t the invention, the verification front end cannot directly obtain theidentity card registration information, so as to facilitate the information safety of the masses.

Description

technical field [0001] This application relates to the field of Internet technology, and in particular to an identity verification blockchain system based on facial features and a verification method thereof.
