Biometric is used for identifying the person based on their traits. Fingerprint is one of the most important and most used biometric trait for person authentication. Fingerprint database must be stored in efficient way and in most secure way so that it is unable to hack by the hacker and it will be able to recognize the person fast in large database. In this paper, we proposed an efficient way of storing the fingerprint data for fast recognition. We are using LT codes for storing the x coordinates of minutiae points and fingerprint images is stored in encrypted form with the coordinates. We are using on-the-y gaussian algorithm for decoding the x coordinates and calculate the value for finding similarity in between two fingerprints.

In this paper, the literature survey of different algorithms for generating encryption keys using fingerprints is presented. The focus is on fingerprint features called minutiae points where fingerprint ridges end or bifurcate. Minutiae points require less memory and are processed faster than other fingerprint features. In addition, presented is the proposed efficient method for cryptographic key generation using finger-codes. The results show that the length of the key, computing time and the memory it requires is efficient for use as a biometric key or even as a password during verification and authentication.
