Abstract: Biometric based cryptography system provides an efficient and secure data transmission as compare to the traditional encryption system. However, it is a computationally challenge task to solve the issues to incorporate biometric and cryptography. In connection with our previous works, this paper reveals a robust cryptosystem using iris biometric pattern as a crypto-key to resolve the issues in the encryption. An error correction engine based on hetro-correlators has been used to evoke the partially tarnished data fashioned by the decryption process. This process determines the non-repudiation and key management problems. The experimental results show that the suggestion algorithm can implement in the real-life cryptosystem.
