hand vein detection

Hand vein recognition is one of many biometric authentication methods based on the absorption of heat rays in venous blood.

The basis of palm vein recognition is the pattern of arteries and veins in a person's hand. The procedure involves irradiating the palm with near- infrared light from an infrared transmitter. The oxygen-reduced blood in the veins absorbs the infrared light, revealing the vein structure. The hand vein recognition method extracts the vein patterns from the camera images photographed by shining near-infrared light on the hand. One such vein pattern is captured from each authorized person and stored as a reference for identifying the person. Veins that are displayed fainter are extrapolated by algorithms.

Authentication of persons via palm vein recognition is used in room access control and for personal identification at ATMs. The palm vein recognition method is also available in combination with infrared technology and temperature measurement. It is one of the most reliable biometric methods with a low false acceptance rate.
