Multispectral Imaging for Biometrics – A Review

Abstract

Multispectral imaging has been used in many biometrics modalities including fingerprint, whole hand, iris and vein recognition. It not only increases the effectiveness of the biometrics recognition but facilitates detection of breaching and spoofing. There are already many commercial biometrics systems based on multispectral imaging available in the industry. However, one type of biometrics is still not 100% strong enough for full proof biometrics system. Multimodal biometrics have been proposed and also in use for more effectiveness. There is still much scope of use and improvement in multispectral imaging based biometrics systems and therefore many researches are going on in this direction.
