An Efficient Biometric Authenticated Protocol for Arbitrary-domain-server with Blockchain Technology
摘要
In the biometric cross-domain authentication based on blockchain technology, to improve the scheme's security and efficiency, this paper proposes an efficient user login on an arbitrary-domain-server scheme based on a Blockchain node. Firstly, the two users login to the client and use the biometric fuzzy authentication technology to register personal biometric information. Then the server sends the information to the non-tamper blockchain node. When the user performs the key verification phase, they can log in on any domain server under the blockchain node, saving time from accessing the original server and improving efficiency. Compared with the relevant literature in recent years, the scheme proposed by us has higher efficiency and functionality. It can prevent replay attacks with a timestamp to achieve the purpose of verification of reception. Finally, we verify the security and efficiency of the proposed scheme.
