Robust Watermark Hiding Against Frame Dropping and Swapping Attacks

Israa Hadi Ali and Safa S. AL-Murieb    

Abstract: As a result of the evolution of the means of communication and to protect the transmission of data over the internet and communication channels, the data of the media such as a video needs for protection and security. To provide that, a watermark will be added throughout the video but it is better to be hided in different location in the frames not in fixed places nor in the background of frames. In this study a blind watermark embedding scheme was explained, by concealing different data in frames instead of embedding the same data. By embedding in most active object, another object was used as guiding to knows the bits that were hidden at each pixel of that object. Instead of hiding the same number of bits from watermark at every pixel of an active object, variation number of bits were concealed according to a homogeneity of a pixel with its neighbors. Also this study indicates how the proposed technique resists frame dropping and swapping attack, although of splitting the watermark into blocks and concealing each block in a frame.
