This paper presents a thorough literature review of robust digital image watermarking
applied in diverse applications. Researchers have already done lots of noteworthy work in …

Digital image authentication is an extremely significant concern for the digital revolution, as it
is easy to tamper with any image. In the last few decades, it has been an urgent concern for …

While formal definitions and security proofs are well established in some fields like
cryptography and steganography, they are not as evident in digital watermarking research. A …

Since the early 90s a number of papers on'robust'digital watermarking systems have been
presented but none of them uses the same robustness criteria. This is not practical at all for …

Digital media is the need of a people now a day as the alternate of paper media. As the
technology grown up digital media required protection while transferring through internet or …

In this paper, we present two watermarking approaches that are robust to geometric
distortions. The first approach is based on image normalization, in which both watermark …

Digital watermarking is one of the most widely used techniques for protection of ownership
rights of digital audio, images and video. Its commercial applications range from copyright …

A robust digital image watermarking scheme that combines image feature extraction and
image normalization is proposed. The goal is to resist both geometric distortion and signal …

Research in digital watermarking has progressed along two paths. While new watermarking
technologies are being developed, some researchers are also investigating different ways of …
