Biometrics are best defined as measurable and/or behavioral characteristics that can be employed to verify the identity of a person. They include fingerprints, retinal and iris scanning, hand-writing and geometry, voiceprints, facial recognition, DNA codes, and other techniques and features.
Earlier they were used for high security applications but now they are being deployed for more ppublic faced applications such as ration cards, passports, ID cards etc.
A character to be considered for biometric examination must have the following characteristics:
-Universality
-Distinctiveness
-Permanence
-Collectability
-Acceptability
-Circumvention
Biometric systems
A biometric system is essentially a pattern recognition system that operates by acquiring biometric
data from an individual, obtaining a feature set from the acquired data, and comparing this feature
set against the template set in the database.
A biometric system may operate in the verification mode or identification mode
Verification mode:In the verification mode, the system validates a person s identity by comparing the captured biometric data with her own biometric template(s) stored system database.
Identification mode:
the system recognizes an individual by searching the templates of all the users in the database for a match.
Biometric system contains the following modules:
1. Sensor module
2.Feature extraction module
3.Matcher module
4.System database module
