Digital copy prot3ction
I can hardly believe that any of these schemes are undefeatable. As soon as the CPU starts talking to a video and sound board, this whole thing becomes easily breakable. All one needs to do is to capture the signals that go to these boards and re-record them. Right? ====================================================================== Thursday February 19, 3:58 am Eastern Time Firms said to agree on digital anti-piracy system LOS ANGELES, Feb 19 (Reuters) - Five giants of the computer and electronics industries have agreed on technology designed to protect Hollywood's most valuable products from being illegally copied, a newspaper reported on Thursday. The Los Angeles Times said Sony Corp (NYSE:SNE - news; 6758.T), Intel Corp(INTC - news), Matsushita Electric Industrial Co (MSES.KL), Toshiba Corp (6502.T) and Hitachi Ltd (NYSE:HIT - news; 6501.T) were expected to announce later on Thursday a proposal to deploy encryption technology that will prevent people from making illicit copies of copyright digital content. The deal could be a breakthrough for the entertainment industry, which has been wary of the ease with which digitally distributed material can be endlessly copied without any degradation in quality, the newspaper said. ``If somebody tries to violate a copyright, it won't work,'' the newspaper quoted Mike Aymar, vice president of consumer products at Intel, as saying. ``The goal is that you'll see products on the marketplace that support this by the end of the year,'' Aymar said. The proposed technology would have no effect on televisions, video cassette recorders or computers already in use, the paper said. It said the agreement was presented on Wednesday in Burbank, California, to the Copy Protection Technical Working Group, a committee that is led by major movie studios and includes representatives of the music, computer, software and electronics industries.

In general, there's no way of building a secure system that prevents copying of information, but permits its consumption. The two are too closely related. The best you could do is a tamper-resistant hardware key on the audio/video card. (This locks you into a design where the content is decoded on the card, which may be suboptimal.) And anyone who can crack the crypto chip can get unprotected digital copies and distribute them. This is probably doable by the same kind of people who set up pirate CD factories. I'm sure Intel knows this. I doubt the content companies do. It's not Intel's goal to create an undefeatable protection system; it's Intel's goal to convince the content companies that it has done so. This seems to have been achieved.

Right?
Of course. Such schemes usually increase the amount of piracy in the long-term, because it encourages people to convert the material into a more easily copied form. If you've ever followed any of the warez scenes, what you find is generally about 1% of the population acutally obtain and convert the material, and the other 99% just trade copies around. (Consider, for example, the number of people who actually know how to dump the contents of an eprom chip versus the number of sites where you can download copies of nintendo/sega/etc games.)
