In this Hi-Tech era, there is a great demand to identify and authenticate the individuals. Till now we are totally dependent upon Passwords and Pin Numbers for identification. How secure are passwords? With the numerous passwords that an individual has to remember, they are often forgotten, misplaced, or stolen. Think of how many different passwords you have to remember: computer passwords, internet site logons and passwords, PIN numbers for the ATM and for credit cards, the list goes on. We are arriving at a conclusion that these technologies are not sufficient for the security of an individual as these are hard to remember, easily transferable, easily stolen and there are many weaknesses. Due to these weaknesses biometrics came into existence.
Biometrics is that study of science that deals with personal human behavioral and physiological characteristics and such as fingerprints, handprints, iris scanning, voice scanning, face recognition and signature recognition. These technologies are far more promising than that which are used currently to identify an individual. This paper highlights some of the benefits and the few limitations of using biometrics for authentication .With biometrics it doesn’t matter if we forget your password or lose your smart card.
The term "biometrics" is derived from the Greek words bio means “life” and metric means “to measure”.
BIOMETRICS refers to the automatic identification of a person based on his physiological / behavioral characteristics. This method of identification is preferred for various reasons; the person to be identified is required to be physically present at the point of identification; identification based on biometric techniques obviates the need to remember a password or carry a token.
A biometric is a unique, measurable characteristic or trait for automatically recognizing or verifying the identity of a human being. Biometrics is a powerful combination of science and technology that can be used to protect and secure our most valuable information and property.
With the increased use of computers or vehicles of information technology, it is necessary to restrict access to sensitive or personal data. By replacing PINs, biometric techniques can potentially prevent unauthorized access to fraudulent use of ATMs, cellular phones, smart cards, desktop PCs, workstations, and computer networks. PINs and passwords may be forgotten, and token based methods of identification like passports and driver’s licenses may be forged, stolen, or lost .Thus biometric systems of identification are enjoying a renewed interest.
