Securing biometric authentication using DNA sequence and Naccache Stern Knapsack cryptosystem

Naccache Stern knapsack (NSK) cryptosystem is a public key cryptosystem which overcomes the drawbacks in the existing RSA system. The proposed system is capable of factoring large integers. The proposed biometric is deoxyribonucleic nucleic acid (DNA) which helps in secure transmission of huge amount of data. It has a structure capable of saving enormous amount of data and also has a unique feature among individuals. DNA provides high security level, long term stability, user acceptance and is intrusive. Combining Naccache Stern knapsack and DNA sequence, a novel biometric authentication scheme is proposed.
