A new biometric using sclera vein recognition for human identification

Biometrics is a technique of identity verification that is based on the principle of measurable physiological characteristics like vein patterns from sclera region. Sclera vein is a new biometric recognition method for human identification. Sclera vessel pattern´s images are saturated and the arrangement of vessel patterns is multi layered and also it is quite complex to extract the features of vein from sclera. In order eliminate high frequency noise components present in sclera, low pass filter is used. To extract the features, a set of vessel segments combine to create Y shaped branches often belonging to same sclera layer. Mapping scheme is based on Y shaped structure in the sclera that is observed to be more stable feature and is used to efficiently eliminate the most unlikely matches. The observational result shows that the proposed method can dramatically provide more secure authentication without compromising the recognition accuracy.
