One of the consequences of all this deep fake software may be the rise in body art. Hidden tattoos that become a kind of personal copyright to your own body image. Much the same way that manufacturers protect their products with registered trade marks and logos. "See its not real, it doesn't have my copyright tattoo on the left shoulder".
I am not advocating people do this but it may become the only way a person will be able to deny any deep-fake image. A sad indictment of civilisation that we will have to voluntarily brand our selves to prove ownership of our own bodies. It may even give rise to a development of holographic tattoos that can't be replicated. Certainly it will be no good having just a small heart with Mom under it as your tag. Everyone is going to have to invent their own special private mark added somewhere private and unseen to ensure they can maintain ownership of their own body image.
A frightening prospect but a sad possibility.
