Energy efficient resource optimized digital watermarking scheme for mobile devices

Abstract

The augmenting attractiveness and convenience of digital manipulation is leading towards mischievous tampering and unlawful reproduction of multimedia content which has become difficult to detect. Digital Rights Management (DRM) has been a functional domain of research for the past few decades, aiming to stop pilferage and tampering in digital media content.

The study reveals that communication has primarily been dominated by the usage of images in any context, furthermore, the use of digital media for images and video have some severe repercussions for the copyright control issues. This problem has further been intensified by the use of Internet and now the intensity is at peak with the use of smart mobile phones. Current trends are about posting and sharing the captured images almost instantly, it has raised the amount of data repository in web-servers saved in the form of images, photos and videos. Across the globe it has been observed a trend of exponential growth in the generation of images and video due to the provision of handy mobile devices with a built-in camera. The current way of distributing data, is leading towards unauthorized distribution in terms of copying the digital content. This technology offers advantage intelligently as compared to the old analog counterpart. Some of these advantages are data transmission, easy data editing of digital content, improved capability of lossless copying of the digital content. The main problem with the Internet enabled mobile device is the lack of control over sharing of the content – both for images and video data. The captured images and video can be used again in ways not envisioned by the owner of the material.
