The research of double-biometric identification technology based on finger geometry & palm print

Common system of single biometric identification is based on single technology, such as fingerprints identification, face identification and iris identification. They have unicity and limitations. So multi-biometric identification technology is valued extensively and becomes the focus of studies. This article, which bases on the features of singular creasure, puts forward multi-biometric identification technology based on finger shape and palm print. It employs different methods of feature collection in view of different areas and designs a hierarchical matcher from coarse to fine so that a multi-biometric identification system is realized with high recognition accuracy and good extendibility. The experimental results demonstrate that this multi-biometric identification technology has not only greatly increased the efficiency of identifying but also ensured the accuracy and security of identification.
