In today's communication era, social media and sharing data through the world wide web plays a substantial role. As per a recent survey, 80% of communication these days is carried out through the Internet. Moreover, the explosive growth of technology has transformed mobile devices into indispensable tools in the computing world. In short, the significant progress of technology has made accessing and modifying data quick and more straightforward. However, the ease of usage of multimedia over the net has opened a door for many attacks and piracy acts, where security and authentication play a vital role. This paper presents a novel video watermarking approach using hybrid discrete cosine transforms for copyright protection and authentication. The main objective of this method is to develop robust and efficient watermarking techniques for videos on mobile devices. Mobile devices function within the limitation of restricted storage and battery life. Therefore, there is heightened emphasis on the analysis of power consumption and execution time during the design of mobile applications. Our preliminary work draws a clear conclusion on the efficient video watermarking approach required for mobile devices concerning power consumption and execution time. In addition, we have illustrated a comparative analysis of existing works on multimedia security and authentication with the proposed watermarking technique on video. [ABSTRACT FROM AUTHOR] |
