Digital images can be easily copied or manipulated by irresponsible persons. The right
property needs to be secured and protected from illegal copies and piracy. Digital …

In this paper, a new robust digital image watermarking algorithm based on Joint DWT-DCT
Transformation is proposed. A binary watermarked logo is scrambled by Arnold cat map and …

Robust and undetectable watermarking scheme is important for copyright protection. This
paper proposes a DWT-DCT-SVD and LWT-DCT-SVD based image watermarking …

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

Despite the passage of more than 20 years of raising the issue of watermarking by Tirkel, the
researchers are still seeking to provide an approach more resistant than existing solutions …

The performance of differential evolution (DE) algorithm is significantly affected by its
parameters setting that are highly problem dependent. In this paper, an optimal discrete …

A combined DWT and DCT based watermarking technique with low frequency watermarking
with weighted correction is proposed. DWT has excellent spatial localization, frequency …

Sharing of copyright documents, images, audios, and videos on Internet has become easier
due to content authentication using digital watermarking. It also finds applications in the area …

Image watermarking technique is an alternative solution to protecting digital image
copyright. This paper proposed a new embedding technique based on different embedding …

With the rapid development of information technology and multimedia, the use of digital data
is increasing day by day. So it becomes very essential to protect multimedia information from …
