On sparse Audio Data Watermarking by Exploiting Haar Transform Structure

Abstract

In the past decade the world has seen a monumental growth in technology. At the same time the technology has lead the human kind to a threat as always there is an exploit of the invention. The current trend is posting all multimedia files on internet instantly without any security. This has lead to tremendous problem to the owners of multimedia file. Thus prevention of multimedia file has given higher priority in recent years. In this paper on sparse audio data watermarking by exploiting Haar transform structure is discussed. Experimental results are provided to analysis the proposed algorithm without degrading the quality of the audio.
