Abstract

If we release digital video into the public domain, we may wish to create the video in such a way that it is impossible for anyone to alter it. Recent advances in video manipulation technology have been used to create systems that can remove or distort objects or people within each frame. In order to detect such attempts at tampering, the system described below embeds the video display information fields inside the video itself and removes the information from the normal (header) locations within the file. Any attempt to alter the video would result in corruption of the information stored within the frame. This would mean that when an attempt to view the video was made, there would be very noticeable visual effects.
