Sandip Joardar, Amitava Chatterjee, Anjan Rakshit · IEEE Instrumentation & Measurement Magazine · 2016
With the advancement in biometric recognition techniques, Palm Dorsa Subcutaneous Vein Pattern (PDSVP) [1] has emerged as a reliable and promising physiological biometric feature. Consequently, PDSVP has been extensively used as a biometric feature in recent research works on biometrics. However, the procedure of automatic data acquisition and PDSVP extraction is quite challenging. This article shows how this problem can be addressed in practice where a real life biometric identification system has been developed utilising near infrared (NIR) imaging of PDSVP of humans, where no fixed setup is employed for data acquisition. We highlight, in this article, three key ideas: automatic data acquisition, PDSVP extraction and, subsequently, biometric person identification using sparse representation based classification. Finally, we highlight the research challenges associated with implementing a Biometric Identification System (BIS) using PDSVP as a physiological feature.
