A review on vein biometric recognition using geometric pattern matching techniques

Due to increasing security issues, biometrics has gained attraction during past years in both academic and commercial domains. They range from physical traits such as retina, face, iris, fingerprint, etc. to behavioral traits such as signatures, gait, etc. Techniques in non-visible spectrum are based on infrared imagery namely near infrared, short wave infrared, mid wave infrared and long wave infrared. Among physical traits vein pattern prove to be more secured as blood vessels are underneath the skin and partially visible to naked human eyes, hence, it becomes hard for intruders to forge. Due to unique physiology of vasculature network, they are fit to be used for biometric authentication. A detailed description of vein recognition technology, arrangement, infrared imaging is presented. A well defined classification has also been provided for vein pattern extraction strategies. This paper is an approach to introduce interested researchers to the scope and methods in this field with detailed classification.
