A Novel Fingerprint Protection Approach based on SoPC Chaotic Encryption

In this paper, a new design approach based on chaotic encryption technique and System on Programmable Chip SoPC to protect fingerprint templates against some attacks is presented. This approach is based on the co-design methodology hardware/software (HW/SW) performed by using Xilinx FPGA platform. The proposed stream cipher algorithm is based on chaotic sequences of the Lorenz system. Simulation and experimental results clearly demonstrate that the proposed approach for protecting biometric authentication system provide a good trade-off between security and performance requirements in terms of efficiency and cost. This system could therefore be integrated into a real time secure access control system.
