Thomas 0 Posted September 1, 2008 We cannot give legal advice in anyway, but all I can say is that if you have a watermark, the footage you have will be able to be held up in court. There is not way video with a watermark can be tampered with. This is why court system still accept VHS tapes. Um....so...no. Watermarks are pretty trivial to work around. Most are just variations on hashing functions and working it backwards is pretty trivial. Once you know what the hashing function is, then you take the edited video, get it's hash and embed it in the right spot in the video file. Share this post Link to post Share on other sites
