Generate an Encryption Key by using Biometric Cryptosystems to secure transferring of Data over a Network

Abstract

Our modern day era faces an inevitable problem of securing our most integrated data and messages. The chief problem is to protect our data in a unique way that could only be worked upon by the sender and the recipient. Most of the traditional techniques probably in-use today, emphasizes on keys that are generated by generic function, algorithms or in random key generators. But question remains whether this key is unique and authentic in nature. Moreover how can these keys be unique to one and one person only? The answer to this would be Biometric Cryptosystems. Biometric Cryptosystems are the newest members in the field of security. The very basis of this Biometric Cryptosystem lies on the very fact that some features of human body are significantly unique to each and every human in the world, such as fingerprint, DNA sequence, Iris, etc. Using those biometric we can generate an exclusive key that will be unique for each and every individual. Now having generated these keys we can use them for encrypting our message. And as because these keys are uniquely generated for individual persons there’s no chance of there will be a matching keys. Moreover as we use RSA algorithm based encryption technique so the encryption lies on two basic sets of keys to decrypt the message. Hence, eavesdropper or third unwanted parties have to acquire two set of keys which adds up to security level of the encryption and hence protect the message from unwanted third parties from acquiring our secret message.
