Bio-Authentication based Secure Transmission System using Steganography

— Biometrics deals with identity verification of an individual by using certain physiological or behavioral features associated with a person. Biometric identification systems using fingerprints patterns are called AFIS (Automatic Fingerprint Identification System). In this paper a composite method for Fingerprint recognition is considered using a combination of Fast Fourier Transform (FFT) and Sobel Filters for improvement of a poor quality fingerprint image. Steganography hides messages inside other messages in such a way that an " adversary " would not even know a secret me ss ag e w ere present. The objective of our paper is to make a bio-secure system. In this paper bio–authentication has been implemented in terms of finger print recognition and the second part of the paper is an interactive steganographic system hides the user's data by two options-creating a songs list or hiding the data in an image.
