A blockchain and multi factor fusion based electronic identity registration and verification system

Abstract

This work proposed a decentralized and multi factor fusion approach to electronic identity registration and verification, and uses blockchain technology to complete the design of the system. The system includes client, identity registration system, identity verification system, electronic signature system and blockchain service module, so as to complete the registration and verification service. The registration system can read citizen’s identity from the ID card by OCR or NFC, processed by electronic signature system, generate a QR code which contain the encrypted electronic identity. The consortium blockchain and decentralized identity storage system are used to store the encrypted identity information. The verification system use identity information plus biometric multi-factor fusion identity verification mode to create a unique ID and using location sensitive hash algorithm to process biometric features can identify a citizen. The system is efficient and trustworthy, with higher security than the previous centralized authentication scheme.
