A Review on Palm Print Recognition Techniques

Abstract

Biometrics helps to identify individuals based on their physiological and behavioural characteristics, which can be used for their personal identifications. Various physical characteristics like retina patterns, iris patterns, fingerprint patterns, palmprint patterns, facial features etc. are utilized for such purposes. Palmprint recognition involves identifying an individual by matching the various principal lines, wrinkles and creases on the surface of the palm of the hand. The basis for using palmprint lies in the fact that since palmprint patterns are generated by random orientations of tissues and muscles of the hand during birth, no two individuals have exactly the same palmprint pattern. Advantages of using palmprint include the fact that such patterns remain more or less stable during one‘s lifetime and also that reliable images of the palm can be obtained quite easily using standard digital imaging techniques. Palmprint recognition uses the person’s palm as a bio-metric for identifying or verifying person’s identity. Palmprint patterns are a very reliable biometric and require minimum cooperation from the user for extraction. Palmprint is distinctive, easily captured by low resolution devices as well as contains additional features such as principal lines, wrinkles and ridges. Therefore it is suitable for everyone and it does not require any personal information of the user.
