Such schemes likely exist, but you would be hard pressed to find any system that wouldn’t also be burdensome for real humans to deal with. This is basically the same thing as CAPTCHA.

For the former, I suspect copyright laws will eventually come around that afford some protection. But as for having something summarize your work, I sense that no copyright laws would be made for that.
