FINGERPRINT

FINGERPRINT - a close look

The flow pattern of ridges in a fingerprint is unique to the person in that no two people with same fingerprints have yet been found.

Uses of fingerprints for person identification are due to the following three qualities that a fingerprint,
v Uniqueness
v Permanence
v Recurrence

Uniqueness:

The quality is very clear from the heading itself, that is no fingerprint is the same
Unless they are taken from same finger of the same person.

Permanence:

This is obvious; the fingerprint doesn’t change through out the life period that is from birth to death.
