Proof Mode

It’s every Science Fiction writer’s dream to have successfully predicted the future.

I did that once. But there’s a wee caveat.

Schneier on Security had a post a few weeks ago about ‘Proof Mode’ for smartphones. This is a way of adding data to a photo to prove that it hasn’t been altered. I predicted image authentication cameras in the Amiga game Hired Guns when I wrote the manual in 1992.
