I made a tool that allows anyone to confirm if a video I am in is authentic or not. https://videoverify.stevej.ca/stevejones

The basic idea is that I read out a token when the video is recorded and then anyone can verify it by checking online. It's obviously redundant if I am sharing a video through my own channel but I think it could be interesting for celebrities and politicians that are often recorded by other people.
