Digital image watermarking provides security, copyright protection, and authenticity to
multimedia content by embedding digital content like text, image, and video. In the modern …

Maintaining secured patient credentials in telemedicine is becoming a critical task. Image
watermarking is one of the solutions to this problem. It is extensively used to protect and …

This study systematically investigated the use of singular value decomposition (SVD) for the
blind watermarking of color images. The proposed algorithm overcomes most of the …

This paper proposes an encryption-based image watermarking scheme using a combination
of second-level discrete wavelet transform (2DWT) and discrete cosine transform (DCT) with …

Firefly algorithm (FA) is one of the newly developed nature inspired optimisation algorithm,
inspired by the flashing behaviour of fireflies that a firefly tends to be attracted towards other …

Desynchronization attacks that cause displacement between embedding and detection are
usually difficult for watermark to survive. It is a challenging work to design a robust image …

Imperceptibility, robustness, and reliability are essential characteristics of image
watermarking. In this paper, two image watermarking schemes, first Lifting wavelet transform …

The widely used watermarking technique is to hide the watermark information through
adding process, which means the watermark is added with the host image to realize …

In this paper, a robust semi-blind watermarking scheme for color images, based on multiple
decompositions is proposed to preserve the copyrights of the owner. Using multiple …

In this paper the merits of block-based blind watermarking in a composite DWT-DCT domain
are explored. To improve the performance in robustness and imperceptibility, the …
