Inverse problem : Can you find a few message bytes in gigabytes of files going back and forth between everyone on the web, or even on an ISP, in order to find a target ?

Much higher probability. And, say, porn to Pakistan will appear in a new light. I would submit that Carnivore from what I have seen deals with the easier forward problem.

Yes, and neither of you have yet been to www.ofoto.com have you? One of my clients is yet another photo sharing site. In two years, customer photos took up over 3 TeraBytes worth of RAID space. Snapshots are 1) original content, 2) very large, 3) numerous as hell, 4) not porn, and 5) there are LOTS of innocent people doing it. Also, when folks upload photos, they don't do just one. They do half a roll, or more, so you don't have to embed a message in every one of them. In addition, one could encrypt the message prior to embedding it. Since it is original content there is no other picture to compare it to, in order to detect alteration. No one else has access to the original, but you. You can further, destroy all non-steg enhanced originals. For a news site that publishes original content, the arguments are the same. What are you going to compare the photos to? It's the original that's been "doctored". If you have support of the local government, there are no "Secret Police" issues, and your "photos" get sent to every web-browser that takes a peek. If you don't keep visit logs then no one knows who has seen the pretty pictures and decoded their content. After having read the article (thanks), I think that Bruce was being improperly dismissive. He applied special case arguments (a specific context) to the general case. The cutter had a dull knife that day ... it happens. The true operational model is quite different from the one that Bruce envisioned in his argument. This is a more complete reason why I suggested that we all start observing the proscription lists, from US State. A site like www.lybia.com or www.taliban.com, operated with such intention, and hosted in a US colo facility, and fed through an SSH tunnel, can otherwise operate with impunity. We would never even know otherwise. We have no such "Secret Police" and I'd really rather not have them. KGB was sufficient trouble in the USSR. We don't need FBI thinking/acting like them. CALEA is bad enough, thank you. Understandibly, I have personal reasons for wanting to see that photo sharing sites remain unmolested and none of the ones, I have mentioned here, are on my client list. Yes, there are counter-measure that those sites could take. They aren't taking them right now. Equally, there are ways around those counter-measures. 'nuff said.

I can actually see lots of applications for steganography; Stealth porn on a public web-site, for example. But for purposes of clandestine communications with and far-flung org, use a news content site that has pictures and imbed messages in the news content pictures. A site like www.Kavkaz.org, for an example, could be used to transmit messages in such a way. Another method is to take advantage of a photo album sharing site like www.ofoto.com. Whom is to know that a mega-pixel image isn't just an image of the family dog? Photos are just the easiest thing, there are other multi-media content vehicles. However, most folks aren't sufficiently talented to be able to post original music. I imagine that the terrorist population has no larger percentage of musical composers than the general populous. Whereas, people generally take snapshots like crazy. I am reasonably sure that Casper the friendly ghost has either thought of, or used, most of them, at one time or another. I can't think that your average terrorist scum-bag has any less of an imagination. So, Bruce Schneier, when posing that problem, must have had his imagination disengaged. There is more than adequate cover story for passing huge JPGs around.

The only way this works is that you route to someone, that has a VPN pipe to somewhere else.... nah, even that won't work. You can encrypt the packets but you can't do it anonymously, unless you are at a public access point. Even so, they can identify the MAC addr. That, plus the time-stamp, and you're nailed. All they need is the motivation. However, given mil-grade VPNs these days, there is no way they can read what you sent. They can only tell that you sent something. However, I just discovered the Steganography stuff in my SuSE Linux distribution, hmmmmm. But, they still know where it came from and where it went. The problem is that, it's looking for a camoflaged needle in a camoflaged needle stack, all of which are capable of changing patterns, like a chameleon. First you have to find it and then figure out what it is. That processing capability doesn't yet exist. Certainly not under WinNT and the typical hardware it runs on. All that they can tell is that encrypted traffic went from point A to point B.
