Looks like he has written tons of very creative bots. They are all very interesting ideas (e.g. http://randomshopper.tumblr.com)

Re: Reverse OCR
#52What (if anything) is this saying about the quality of the OCR process? Especially since none of these seem human readable.
Only a reminder that the OCR process looks nothing like what humans do.

Several of them did seem readable to me.

And? It still has key sizes, the enemy still knows the system.
Disclaimer: [1] From what I understand, ideally stego would be used in conjunction with encryption. First, you would encrypt your message, then you would use stego to hide it. If the stego is good, it would be a computationally intractable problem[2] for your adversary to determine whether there was indeed a message hidden within the data they were analyzing, with greater than 50% accuracy. That said, I'm not sure ho…
But the message as is right now looks like random lines they could be disguised as something like scratchs on the surface of a cellphone case from keys, or on the paint on the inside of a toolbox and just look like regular ware and tear. If you wanted to be really clever it could probably be hidden in the grain artificial wood textures.

#57Could this be used in a pseudo reverse CAPTCHA by showing a series of words, and asking the user to say which is not human readable?

Steganography is solidly a "security through obscurity" thing. Sure, we comp-sci people don't care about that, but spies do. There was that Russian Spy who was transmitting data for years on her Facebook account through steganography pictures on her Facebook account. http://www.technologyreview.com/view/419833/russian-spies-us... The FBI didn't know about it until after she was caught. So believe it or not, Steganogr…
> Steganography is solidly a "security through obscurity" thing. I never really understood why is it so. Encrypted data must be indistinguishible from random, thus, if you replace any random projection of a file with your data, the result should be completely unrecognizable. It shouldn't really matter if your algorithms are public. Is the problem that it's hard to get random projections from modern data? If so, why n…
People don't typically exchange randomised versions of their data.
