A Durable Biometric Authentication Scheme via Blockchain

In the digital era, one of the aspects is data security, where the combination of biometrics with blockchain is introduced as an advanced and durable technique to protect sensitive information. In modern society, biometric systems are widely employed instead of the password as an authentication process with high-level security, is complicated to hack the system by the hacker. At this juncture, the blockchain can provide high-level security as a fast-accessing process in an efficient manner. Any authentication process refers to some conventional hashing policy for the preparation of digital signatures. The same digital signature can process with the blockchain technique by referring to the hashing approach is discussed in this paper.
