    I don' think its a bad idea to have a watermark as long it can achieve the following:

    Integrity of source
    Playback on any system

    How the watermark can be useful is if it is treated like a serial number not a lockout device. Suppose I am a musician and I want to sell some MP3s. If I can uniquely mark all the songs I sell, I can track which user decided to violate fair use if I see that unique mark on a peer to peer network.

    but mp3's are just so entrenched it'll be tough to get the average user to convert.

    I'm not so sure I'd agree. Remember when GIFs were all the rage? I thought no one would ever convert to JPGs because GIFs were so popular. Now, you hardly ever see them. I know, JPGs are better at compression, so maybe that's the reason.

    Maybe a better comparison would be PNGs compared to GIFs or JPGs? I use PNGs all the time, but I don't have a feel for how popular they are in general.

    I guess my point is that if there's a compelling reason, people will switch file formats in a heartbeat. For that matter, I know people who switch MS Word formats every few years or so. Oh, wait...

    "You can't prove a negative." --Professor Rowe, on the first day of law school

    I have friends who work in the security industry and crack codes for a living. Every time a watermarking scheme is publically proposed, they laugh long and heartily. The simple fact of the matter is that a system designed to check for a watermark can easily be changed to invalidate the watermark. Watermarks are necessarily little bit-flipping programs that don't alter the outward appearance of the media they are attached to, so what makes record execs and PHBs so sure that they can't be removed?

    The only watermark that can't be removed is the watermark that can't be detected. And that doesn't help the digital rights management fascists one bit. So why do they bother?

    Well, they still think it's a "deterrent." Just like Macrovision is a "deterrent" when you can buy filters to block it for under $25 on eBay. Sooner or later, though, the world is going to have to learn that information wants to be free, that trying to restrict the flow of bits on the information superhighway is futile, and that selling simple numbers and calling it "property" is patently absurd. Mathematics is a part of nature, and nobody owns nature; the sooner our laws are brought into line with this simple truth, the better.

    Do you want to live in a world where there's Draconian DRM or a world where there's DRM that makes casual piracy hard?

    OK, there's the third, remote possibility that we'll end up in an another world in which "information wants to be free" rules, but the sorry, true fact is that whatever information wants, people want to own information and charge other people for it. Especially people with lots of money. And therefore power, and therefore clout to shape the world.

    There's a growing body of opinion that holds the best way to keep us from getting draconian DRM is NOT to shrilly scream about free information/content and drop into a frenzy of distribution violations, but rather, to show how a mild solution can give us the best of "fair use" and "new economy" rules while not totally threatening the status quo (just enough to keep 'em on their toes).

    Here is a possible scenario. Watermarking only works if everybody is using it and everybody is detecting it--otherwise, people will just end up using the non-watermarked codecs. The two companies will use patented technology for watermarking. They will then go the MPAA and RIAA and similar cartels and unite with them to pressure Congress to adopt their watermarking scheme. The end result is tidy for them: DivX and Fraunhofer get complete control over codecs, and copyright holders can completely control who does what with any content, whether it's their or independently created. And Microsoft will likely like it too, because they can afford to license such mandated technology and enforce its inclusion in their software.

    Excluded are open source software developers, researchers, and independent creators of content.

    Despite the amusing conspiracy angle you've taken, I don't quite buy it. I think it's more likely that as a company starts off a new service, they are much more lax on restrictions because the user base is small enough that such restrictions aren't really needed. However, as the user base grows and grows, doing certain things become infeasible if you still want the service to function for everyone. Hence, gradually more and more restrictions are put in place, in order to preserve the best possible experience for all users. This same pattern is true of almost every type of service that has ever had to "grow" a userbase.

    AOL isn't a very good example of this. AOL became popular because of marketing and ease of use--they still continue to attract new subscribers despite how hard it is for users to email warez to each other. Many web-based email sites better exemplify this scenario. One in particular started with no restrictions on inbox size or outgoing message size, for example. However as its userbase grew, restrictions were implemented so that a small few couldn't ruin the service for everyone.

    People, people, people. We should really all be supporting this technology. This really is the answer that we want.

    Let's make a few assumptions.

    1. Someone can make a non-trivially breakable watermark technology. One that stands up to peer review without threats of legal ramifications.

    2. Content providers can then use this watermarking technology on a reasonably fine scale - probably not individually watermarking every CD, but perhaps broken down into regions. Digital downloads could be individually watermarked, given enough CPUs.

    What would this do? It gives the content providers ammunition and evidence to go after the big time copyright violators. Those that are burning CD's and turning around and charging money. Granted, a lot of these folks are probably overseas...

    It allows us to use our digital media as we see fit. We can listen to it on our PCs. Download it to our Rios. It still allows us to swap digital media among friends. Content providers aren't going to go after the small fry, there's no return on investment.

    This allows us to say to our congressmen, "Yes we care about and value copyrights. But we also value fair use."

    This is a happy medium ground.

    And being the crazy optimist that I am, this is the way I see things eventually settling down. The question is will it settle down in 1-2 years, or 10-20?

    Yes, there are all sorts of immoral and possibly illegal things hardware manufacturers can do by automatically scanning for watermarks, but the watermark itself is pretty much morally neutral.

    I beg to differ. Given the purpose of electronic watermarking (locate illegal copies in the wild and be able to track it back to the specific customer who leaked it), imagine the consequences. The entertainment and software industries already calculate losses on a per-pirate-copy basis. A thousand illegal copies is a thousand lost sales and $price*1000 lost income.

    If you leak a watermarked product, you're pretty much done for economically if they prosecute (which they have no reason not to, since it's the entire idea of the watermarking to start with). Try to tell their minion of lawyers that your copy was stolen, for an exercise in futility.

    You'd damn better guard that watermarked product with your life, lock it in somewhere safe, never talk about it, cause you don't wanna deal with these guys if you "pirate" it by accident!
