Secure Data Transmission Using Audio Steganography
K. Sakthi Sudhan · i-manager’s Journal on Electronics Engineering · 2012
Finding a message should only be possible with knowledge of the key that is required to uncover it. So, this method will be more effective when compared to the cryptographic methods. In case of pervasive hacking by rapid selection one cannot be able to retrieve it exact message format as the inbuilt. Cryptography serves for this valuable purpose. Thus, a method called dual steganography serves well for the digital communication fields. The name 'dual' itself retrieves its cause such that two methods both combinations of cryptography and steganography is used. In this paper, a secret message from an audio file or a text file is first encrypted and then it is embedded into a carrier audio file. The researchers assumptions are the audio files are strictly in .wav format and the carrier audio file should be eight times greater than the secret audio message file. The paper is organized as follows: In section 2 the existing audio steganography methods are discussed. Section 3 deals with the overall system model with the proposed audio steganography technique. In section 4 and 5, the experimental results and conclusion are discussed.
