Do you happen to know whether the individual watermarking thing works? By which I mean, do these typically end up on torrent sites?

- dylan604 5y agoWhen I was first introduced to the forensic watermarking software, I was very skeptical. I, along with fellow curious coworkers, took it upon ourselves to see if we could circumvent it. We did all of the things their marketing people claimed it could do (inverting, flipping, scaling, skewing, combos of these, etc), and at the end of each of these tests, the ID could be read back. There were of course a few things we could do to make the ID unreadable, however it resulted in an unwatchable bit of video that would no longer be meaningful. The system does work. Every screener season I was involved, people were caught. They didn't always make the news because not everyone released to torrent sites. There are other screener "crimes" that don't involve the police but perhaps loose future screener privilages. There are other forensic techniques for feature films screened in theaters to catch camcorders. Modified versions of the content could be sent to different regions of the globe. When a pirated copy was found, they could look for these modified portions of content to narrow down what region was copied. These are innocuous things like changing the color of something in the background that oridinary people wouldn't even notice if it was changed from shot to shot. You'd also have to see the content from multiple regions to even possibly know that it was done. This is just one example.
