We have implemented a robust image watermarking technique for the copyright protection
based on 3-level discrete wavelet transform (DWT). In this technique a multi-bit watermark is …

The improvements in internet technologies and growing demands on online multimedia
businesses have made digital copyrighting as a major challenge for businesses that are …

Recently, by means of technological innovation in communication networks and information,
it has assisted healthcare experts across the world to seek high-quality diagnosis as well as …

In this paper we propose a blind and highly robust watermarking method consisting of two
embedding stages. In the first stage, the odd description of image is divided into non …

This paper introduces a robust image watermarking technique for the copyright protection.
The proposed method is based on 3-level discrete wavelet transform (DWT). Encoded secret …

Information hiding or data hiding, also known as watermarking, has become a part and
parcel of covert communication and copyright protection. Maximizing watermark payload is a …

This book describes the need of copyright protection for multimedia objects and develops an
invisible image watermarking scheme to serve the purpose of copyright protection. Here …
