High Performance and Energy Efficient Image Watermarking for Video Using a Mobile Device

Abstract

This article describes the basic information hiding technique that is most commonly used nowadays. As evolution in the communication media has made information access much easier but has also increased the risks of invading privacy and ownership. To overcome such threats, watermarking is one of the most suitable methods used for hiding information. It is the process of inserting audio, video, image or text for owner verification. A study on spatial and temporal domain watermarking is conducted. An experiment is carried out for the analysis of power and time consumption while inserting and extraction of the watermarks. For better understanding of the concept, embedding of an image on a video was performed using a computer and a mobile with similar logic. This concluded that the watermarking process can be implemented by both computer and mobile phones. Extraction of image was done with PSNR value that was inserted on a video. Only limitation found in this process was tracing back to the source of content theft and that is covered by forensic watermarking.
