Abstract
In order to protect and secure a video, watermark is added within data of video, to avoid conceal
the watermark in fixed location or in the background of the frames of video, this paper indicates
watermark concealing algorithm based on selecting two specific objects that are characterized with
activity in their motion over the frames of video file. In this paper the watermark is concealed in
objects of video based on host and reference objects, with the variation number of concealed bits in
any pixel of object according to the proposed hiding schema that is explained in this paper instead of
hiding the same number of bits from watermark. Also, in this work we illustrate the algorithm of
watermark hiding in one frame, and we can extend this work by applying this algorithm in each frame
based on the host and reference objects.
