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 …

In this paper, a novel image watermarking method is proposed which is based on discrete
wave transformation (DWT), Hessenberg decomposition (HD), and singular value …

Image watermarking can provide ownership identification as well as tamper protection.
Transform domain based image watermarking has been proven to be more robust than the …

Existing techniques of watermarking make use of transform domain to have better
robustness towards attacks. Here, we propose a novel learning based auto-encoder …

This paper proposes a new algorithm of blind color image watermarking based on LU
decomposition. Because of the first column the second row element and the first column the …

Deep learning-based methods have been popular in multimedia analysis tasks, including
classification, detection, segmentation, and so on. In addition to conventional applications …

Digital watermarking is a method to provide authenticity and copyright ownership to digital
content by embedding any presume content like audio, text, data or video into the original …

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 …

To keep a better trade-off between robustness and imperceptibility is difficult for traditional
digital watermarks. Therefore, an adaptive image watermarking method combining singular …

Issues such as content identification, document and image security, audience measurement,
ownership and copyright among others can be settled by the use of digital watermarking …
