Abstract: Blockchain's core features are “decentralized” and “non-real-name,” so blockchain technology is well suited for authentication scenarios. Firstly, this paper expounds the history and principle of identity authentication and blockchain development. Secondly, it points out the security problems of traditional identity authentication mechanism due to centralized storage. On this basis, it also put forward two-factor identity authentication model based on blockchain and face recognition, defnes and describes the participants and components of the model, details the specifc processes of each operation involved in the model. Finally, the security of the model is proved by simulating attack and resistance analysis, and the availability of the model is proved by efciency and storage analysis.

Key words: identity authentication, blockchain, decentralized, face recognition, two-factor
