FPGA-Based Embedded System Implementation of Finger Vein Biometrics
The biometric authentication method provides high reliability and security for the purpose of personal authentication. But so far, a real time embedded system for implementing the same has not been built. In this article, a FPGA-based embedded
system is designed for the purpose of personal verification using infrared finger vein biometric authentication is presented. It is a challenging problem because the creation of the biometric authentication system in the resource constrained embedded system is very difficult. The major modules used in this system are:
- image acquisition
-image pre-processing,
-feature extraction
-matching

The minutiae extracted from the vein pattern image is used for the purpose of feature extraction. The biometric matching uses the method called Modified Hausdorff Distance. The system is implemented on the Altera Stratix II FPGA hardware board with Nios2-Linux Real Time Operating System.
