Cryptography is an important field in the area of data encryption. There are different cryptographic techniques available varying from the simplest to complex. Biometrics is the science of identification of humans by their characteristics. Fingerprints are the most widely used parameter for human identification amongst all biometrics. Fingerprint comprises a set of minutiae. The orientation of the minutiae uniquely identifies a fingerprint. This feature has been exploited to generate a unique code for an individual. The code is further modified to obtain a 56 bit key for use in the symmetric key encryption namely Data Encryption Standard (DES). DES is one of the mostly used symmetric key cryptography algorithm in the present day apart from the Advanced Encryption Standard (AES).
