Increasingly, smartphones come embedded with more and more advanced biometric
recognition systems. The high quality embedded sensors capture the biometric data which
helps to get higher biometric recognition accuracy and security. On the other hand, these
sensors increase the cost in terms of battery usage, take up extra physical space also some
hardware cost. This paper investigates the reliability and effectiveness of fingerphoto ver-
ification system developed using a smartphone. Consequently, biometric samples can be
collected without the need for dedicated hardware, thus providing a cost-effective and re-
liable way to do biometric authentication. The focus of this paper is to study various
baselines to evaluate the readiness of the technology. To this extent, we present a com-
parison between three non-commercial baseline systems with one commercial system. The
commercial off-the-shelf (COTS) system shows the best performance of an equal error rate
of 6.08%.
