Abstract

Data security is one aspect of the digital era, and it is recommended that biometrics and block chain be used together as an original and reliable method of protecting sensitive data. As high-level authentication methods, biometric technologies are often utilized in the modern world in place of passwords because they are more difficult for hackers to crack. At this point, the block chain can actually serve as a rapid access method while providing high degrees of security. Any authentication process generates digital signatures using a common hashing method. This paper describes the hashing method's use in the block chain system to process identical digital signatures.
