摘要: 区块链的核心特征就是去中心化和非实名化,因此区块链技术很适合应用于身份认证的场景.首先,阐述了身份认证和区块链的发展历史和原理;其次,指出了传统身份认证机制中由于中心化存储而存在的安全性问题,并针对问题提出了基于区块链和人脸识别的双因子身份认证模型,对模型的参与方和组件进行了定义及描述,详细介绍了该模型涉及的各操作的具体流程;最后,通过模拟攻击与抵抗分析证明了模型的安全性,通过效率及存储分析证明了模型的可用性.

关键词: 区块链, 人脸识别, 双因子, 去中心化, 身份认证

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
