Biometrics

Biometrics is the automated identification of human identity through the measurement of repeatable physiological or behavioral characteristics”.
In simple terms identification means the search of a biometric sample against a database of other samples in order to confirm whether the donor is already present in, or new to the database.
Verification refers to the one to one comparison between a sample and another to ask the question, are you who you say you are. The majority of access control applications utilize verification techniques, rather than attempting searches of databases, which could compromise accuracy and raise costs.
