Abstract

Steganography is technique to hide the secret data within a cover media such as digital images, sound files, video files in such a way that the existence of the message remains same. Audio stenography technique hides the secret data such as text or images in the audio signals. In this paper we proposed a technique for hiding the text message into audio signals using Improved LSB technique. In the proposed system the combination of Adaptive Huffman and LZW algorithm is used to compress the text message. Various test cases are performed on various inputs and results of the proposed system are evaluated on the basis of SNR and Compression Ratio, Time and MSE. Experiment results shows that the proposed system give better pe rformance than that of existing systems.
