Abstract

Biometric system is widely used for identification or verification of a human based on their physical or behavioral characteristics has gained more importance in today’s society where security of information is essential. Biometric systems based on hand geometry are gaining important in low to medium security applications. Hand geometry based identification systems utilize the geometric features of the hand like length and width of the fingers, diameter or perimeter of the palm also the shape of hand. The proposed system is an identification system which uses hand geometry features for user authentication. The hand shape is used which consists of only those features that cannot vary with small variation of palm position. Users can place their hands freely without the need for pegs to fix the hand placement. Most of the hand geometry systems need pegs for fixing the placement of the palm on the scanner so that hand image will capture in same pattern. The proposed system is capable to allow the user to vary the positioning of the hand on the scanner or in front of digital camera. Hence the proposed has no restriction about identification. It is capable for correct identification of human under the limited training samples.
