Finger Knuckle Print Recognition Techniques-A Survey

-----------------------------------------------------------ABSTRACT----------------------------------------------------------Biometric traits are now highly explored by researchers to establish a system that can be used to accurately identify a person. Personal identification based on biometric features is becoming more popular these days because it is more reliable than traditional methods and has got numerous applications. The performance of such a system depends on the biometric characteristic that is utilized. Many traits like fingerprint face iris, palm vein, DNA and many others have been used for personal identification. One new biometric trait that has attracted researchers in the recent years is the finger knuckle print. The finger knuckle print refers to the inherent skin patterns that are formed at the joints in the finger back surface. Recently it has been found that the finger knuckle print is highly rich in textures and can be used to uniquely identify a person. Hand based biometrics have the advantage of higher user acceptability and this new trait has an added advantage of not getting easily damaged. This paper presents some of the methods used by the researchers for acquisition and techniques used for recognition systems based on finger knuckle print. Most of the researchers have made use of the database containing 7920 samples collected from 660 individuals that is publicly made available by the Hong Kong Polytechnic University. Performance comparison of the different techniques proposed in the literature is also presented.
