This paper proposes a hand-shape biometric device with two sensors, respectively working in the visible and 1470-nm bands. The inclusion of the 1470-nm band sensor is to improve both security and performance. The security is improved by in- cluding a spoof detector and the performance by combining both bands.Thespoofdetectorcombinesthreeskindetectionindicesob- tained by comparing the reflectance of the hand image in the red, green, and blue bands with that from the 1470-nm band. The hand tissues reflect the visible radiation while absorbing the 1470-nm radiation. The band combination is carried out at a score level which reduces the error rate because different images were ob- tained under different physical principles (reflection and absorp- tion). The system performance ha sb een evaluated with ad atabase containing 10 acquisitions from each of a group of 100 users and 390 acquisitions from 62 imitated hands made of different mate- rials. The experimental results confirm both security and perfor- mance improvement.
