Security role of biometrics in electronic transactions

Abstract

As electronics transaction are increasing in day-by-day in common man's life therefore it is luring to people involve in unlawful activity to commit frauds in electronics tractions also. They understand the weakness of the system and exploit. Though may very effective Public-Private-Key based algorithms have be developed providing security for transmissions of electronic data still have room for leakage of key? If we use biometrics based encryption in electronic transmission then we can ensure most safe transmission of data, especially in commercial tractions. Let us understand the biometrics and area which must use it. In any application having electronic communication has some most common security requirements are Authentication, Privacy/confidentiality, Integrity and Non-repudiation. The Cryptography not only protects data from alteration or theft, but it can also be used for user authentication.
