Abstract

With the revolution of information technology and Wide Area Networking, data has become less and less private where the access of media as well as the attempts to change and manipulate the contents of media data has become a common a common case. Digital Watermarking is an important issue in the field of multimedia security protection. The digitization of the world has expanded the concept of watermarking in order to be used in authenticating ownership claims and protecting proprietary interests. . It is essential to have techniques for authentication of the content. This paper aims to use the Discrete Wavelet Transformation as watermarking technique and showing the results after applying Haar wavelet, Biorthogonal wavelet and Discrete Meyer Transformation. The results presented here shows that Biorthogonal wavelet is more robust than other two other wavelet transformations.
