With the explosion of data generation, getting optimal solutions to data driven problems is
increasingly becoming a challenge, if not impossible. It is increasingly being recognised that …

Swarm intelligence (SI), an integral part in the field of artificial intelligence, is gradually
gaining prominence, as more and more high complexity problems require solutions which …

One of the main methods used to provide security for medical records when exchanging
these records through open networks is digital watermarking. In order to preserve the …

In this paper, a blind dual watermarking scheme for color images is proposed by embedding
an invisible robust watermark to protect copyright, as well as a fragile watermark is …

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 …

Recently, piracy and copyright violations of digital content have become major concerns as
computer science has advanced. In order to prevent unauthorized usage of content, digital …

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

In recent years, we face an increasing interest in protecting multimedia data and copyrights
due to the high exchange of information. Attackers are trying to get confidential information …

Watermarking is an important technique for protecting sensitive e-multimedia data and
intellectual property. Watermarking techniques are used for many applications such as …

The existing watermarking algorithms invariant wavelet domain are weak at resisting
geometric attacks and have small embedding capacities. In this paper, a robust double …
