What is Biometrics?
Biometrics are automated methods of recognizing a person based on a physiological or behavioural characteristic. The word biometrics means Biological Measurements. Therefore in this way we can use computers to recognize persons.
Physiological characteristics means Fingerprints, Retinal and Iris Patterns, Hand and Finger Geometry, Facial recognition etc.
Behavioural characteristics means Voice Patterns, Signature etc.
There are different biometric solutions. Some of them are Finger Print Recognition, Iris Pattern recognition, Facial Recognition, Voice Pattern Recognition, Hand and Finger Geometry etc. In all these biometric solutions the details about the physiological/behavioural characteristics are entered into a database. When the user uses the sytem the characteristics required for the system are scanned and a template is formed. It is checked whether there exists a match for this template with any of the records already stored in the database. If a match is found, the user is allowed access. Otherwise the user is denied access.
Each biometric solution can be used in two different modes.
In Identification mode, where the biometric system identifies a person from the entire enrolled population by searching a database for a match.
In Verification mode, where the biometric system authenticates a person's claimed identity from his/her previously enrolled pattern.
Applications of Biometrics.
Improving airport security.
Strenghthening our national borders in travel documents, visas, passports etc.
In peventing ID theft.
