Biometric modalities are being used for person recognition for over 40 years. Face has been extensively analyzed as a biometric modality. Palm vein is a permanent and difficult to spoof, modality. For person authentication, palm vein performs better than face. Fusion of both the modalities yield recognition rates that are higher than those obtained individually. This paper presents a survey of various techniques used for authentication of a person, based on face, palm vein and fusion techniques involving both modalities. It discusses some iconic techniques, their limitations and how those were overcome in different ways in new techniques. It concludes with major problems to be analyzed in future and open areas of research.
