Now if I were going to design a secure messaging system ...
I'd start with my encrypted message handwritten on a piece of paper flipped in front of a webcam amongst a load of random characters on other pages.
If you've got your tradecraft right, you can use a public webcam that's pointed at a city square or something.
With the killer punch that if there are people doing this today we'd never know, because all the spy agencies are obsessed with digital encryption.
On a similar note, does anyone here know what that postcards in newsagents windows in London *really* say ?
The more the spooks show they rely on using digital technology to "operate", the more ways I could dream up of frustrating them.
We already have an internet dead letter drop mechanism in Usenet and binary newsgroups. Good luck finding any secret communications there. Especially if they were encoded by photographing a handwritten notice (in Farsi) and posting the JPEG.
Biting the hand that feeds IT
