BIOMETRICS
Biometrics is the latest buzz in the
field of data security. Biometrics uses the physiological or the behavioural
characteristics of human being. In biometrics these characteristics is
recognized automatically to provide access to the data. As few of the
characteristics of human being is so unique. We are going to use such
characteristics to provide the security for data. So we have no other way other than using the
Physiological or behavioral characteristics of human being to provide the
security. The below picture clear shows the definition of biometrics Biometrics is of two
kinds: one deals with the physical traits of the user (Retinal scanning,
Fingerprint scanning, DNA testing etc.,) and the other deals with the
behavioral traits of the user (Voice recognition, Keystroke dynamics, etc.).
If
someone is going to use the biometrics for the first time, the person is called
as enrollment. In this stage, information of that person is stored in the
device. One should make sure that information given in the device should be
secure.
When the same person uses the device for the
next time, the information stored in the biometric system during the enrollment
is compared with input provided by the user. If the information matches, the
person will be allowed to use the device. One should make sure that storage as
well as retrieval of the information is done in a secure manner.
