Fingerprint identification

Fingerprint identification is based on two basic premises:
(i)persistence: the basic characteristics of fingerprints do no change with time; and (ii) individuality: the fingerprint is unique to an individual.
Since biometric identifiers cannot be easily misplaced, forged, or shared, they are considered more reliable for personal identification than traditional token or knowledge based methods. Table 1 summarizes typical applications of biometrics for positive person identification.
