A Biometric Solution To Cryptographic Key Management Problem Using Iris Based Fuzzy Vault

Abstract

Reliable information security mechanisms are required in the today"s era of cyber theft. Traditional Cryptography is a powerful mechanism to achieve information security. Current cryptographic algorithms (e.g., Advanced Encryption Standard (AES), Data Encryption Standard (DES), RSA) have a very high proven security but they suffer from the key management problem. Human identification is also a challenging field. That is why if we can make a blend of cryptography and biometric then it becomes a upcoming security tool. Using unique biometric identity of a person the keys for cryptosystem can be made secure. Iris is one of the proven and accurate means to identify person and it does not change throughout life of a person. This paper presents a biometric solution to cryptographic key management problem using iris based fuzzy vault.
