Digital watermarking is a technique for resolving copyright law in E-Commerce. In this article
a combined watermarking method based on Discrete Wavelet Transform (DWT) and …

To protect the copyright of digital image, this paper proposed a combined Discrete Wavelet
Transform (DWT) and Discrete Cosine Transform (DCT) based watermarking scheme. To …

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 …

Image watermarking technique aims at high imperceptibility of the embedded watermark
with minimal distortion in the watermarked images. In frequency-domain, block-based …

Digital watermarking is a technique to secure privacy of digital information and it's an
important research area. There is a high risk in piracy with technology developments …

In this paper, a digital watermarking algorithm for copyright protection based on the concept
of embed digital watermark and modifying frequency coefficients in discrete wavelet …

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 …

A hybrid and robust digital image watermarking is suggested by using advantages of both
frequency domain and wavelet domain. In this method, the most suitable color component of …

In this paper, a digital image watermarking algorithm based on DCT transformation is
proposed. The imperceptibility and robustness is provided against different attacks. A binary …

Digital watermarking techniques have been developed to protect the copyright of multimedia
objects such as text, audio, video, etc. In this paper, we propose a new digital watermarking …
