To overcome such problems or to provide maximum security, a technology that exists from 14th century, namely, Biometrics can be a solution. Biometrics is defined as automated methods of verifying or recognizing the identity of a living person based on a physiological or behavioral characteristic. Each of the methods to identify an individual is unique and can realistically provide a value that is technically viable and feasible to prove the bonafides of the individual concerned. However, these technologies need to be perfected without creating an unnecessary hype on the technology front and provide the necessary information to the security issues that are the need of the hour. The methods explained are the basics of biometric subjects and the details require to be addressed based on the applications that will be critical to the end user.
Fingerprint is the oldest of the biometric technologies in use.
It is estimated that the chance of two people, including twins, having the same print is less than one in a billion. Many devices on the market analyze the position of tiny points called minutize, the end points and junctions of print ridges. For fingerprint recognition products, several tests exist, such as dusting for latent prints on the device, lifting them with tape, and reapplying them to the reader. In all cases, the devices were proved fool proof. This is a reflection of the relative maturity of fingerprint recognition technology, which has been in use in a number of environments for decades.
