Biometric Identification

Biometric identification methods may be clustered based on the chief physical characteristic which provides itself to biometric identification:

* Hand Geometry – is the comparison and measurement of the various bodily features of the hand. Even though hand geometry does not possess the same level of individuality or permanence as with some other features, it remains a popular method of biometric identification.

The veins inside the palm of the person are read as black lines. The palm vein authentication possesses a high degree of validation accuracy because of the intricacy of the palm’s vein patterns. Since the palm’s vein patterns are inside the body, the authentication system would a hard one to fake. The system does not also need contact. Thus, it is hygienic for utility in public places.

* Retina scan – offers an examination of the capillary blood vessels that are found in the rear of the eye. This pattern stays the same all through life. Retina scans use a low intensity light in order to take a picture of the pattern that is created by blood vessels. This technology was first recommended in the 1930s.
