Biometric Image Recognition For Secure Authentication Based on FPGA: A survey

Field Programmable Gate Arrays (FPGA) based biometric image recognition is one of the highly secure authentication technologies. It bases on personal unique features of each person. The employment of FPGA provides specific reprogrammable hardware solution that can be properly exploited to obtain a reconfigurable recognition system. This paper presents a survey of biometric image recognition that relies on FPGAs. These biometric recognition approaches include face recognition and iris recognition. This paper is a brief review of the concept and structure of biometric recognition systems. Furthermore, several recognition algorithms are also surveyed in this work. In addition, a summary of the state of the art of each recognition type is also provided as a background for findings in biometric recognition systems.
