This paper gives an overview of the research and implementation challenges we encountered in building an endto-end natural language processing based watermarking system. With natural language watermarking, we mean embedding the watermark into a text document, using the natural language components as the carrier, in such a way that the modifications are imperceptible to the readers and the embed...

Digital watermarking and image processing is a rapidly evolving area of research and development. One key challenge in the research problem is that we are still facing today is the development of truly robust, secure and transparent watermarking technique for different digital media including video, documentary text, graphics, images, and audio. In digital image processing, detection and extrac...

Steganography is the ability to hide secret information in a cover-media such as sound, pictures and text. A new approach is proposed to hide a secret into Arabic text cover media using "Kashida", an Arabic extension character. The proposed approach is an attempt to maximize the use of "Kashida" to hide more information in Arabic text cover-media. To approach this, some algorithms have been des...

Digital Watermarking is a technology used for the copyright protection and authentication of digital application. The commercial activity on the internet and media require protection to enhance security. We proposed a new invisible non-blind video watermarking in Quick Response (QR) code technique. In one video frame we embed text message into QR Code image and further embed logo into QR-Code i...

The increasing number of problems related to the ownership protection of the multimedia content & its authentication due to digital revolution had lead to evolution of digital watermarking techniques. Digital watermarking provides a viable solution in minimizing this problem and boosting the confidence among multimedia content i.e. text, image, video, audio providers to make available there con...

As a solution to copyright protection of the digital media, digital watermarking techniques have been developed for embedding specific information to identify the owner in the host data imperceptibly. Nowadays, most watermarking methods mainly focused on digital media such as images, video, audio, and text, and very few watermarking methods have been presented for 3D models relatively. In the p...

With the rapid evolution of processing multimedia technologies (text, audio, image and video) and its internet application (wide and easy transmission of digital multimedia contents), the copyright protection has been receiving an increasing attention. Among the existing strategies to protect multimedia online, digital watermarking provides a promising way of protecting data online from illegal...
