Secured Digitally Embedded Audio Transmission Based On Discrete Transformation
Publication Date : 18/03/2016
All sorts of data today is getting digitized and internet among others is the easiest and a very effective source and host for sharing information. So, it becomes very important to track, protect and monitor the data and maintain its security, Secret, data integrity, authentication, robustness and ownership. And, techniques like steganography, watermarking and non repudiation of messages help us to do so. In steganography, information is hidden inside the data (like image, audio, video, text) and the data is kept secret maintained as only the sender and the receiver know how to retrace the information. Watermarking is used to hold the secret data. In this paper, a secure way of Audio- Watermarking is implemented using Distinct Wavelet Transform (Haar Wavelet) and Distinct Cosine Transform. It requires a cover file that can hide the message that is to be transmitted.
