Yah. This same was mentioned on a digital watermarking forum I read. A great deal of my own research centers around attacking & finding weaknesses in such schemes, and as it's science I am obliged to write code to prove my hunches. This bill may make me a criminal! This struck a nerve at the time, because the fella who mentioned the bill was (a) an employee of a watermarking company and (b) mad as Hell at the rest of us for developing watermark attack software. If that law was on the books (and the guy was the CEO or such) at the time, I have no doubt a few of us would be in big legal trouble. Now, I should disclaim that that particular company is much more understanding than that one guy. I met a bunch of their employees (as did a couple other attack-makers) at a conference, and they were quite clueful about the importance of watermark robustness research. However, countless other watermarking startups exist. Many have the whole business bet on a potentially breakable scheme. Further, watermarking involves people from non-crypto disciplines, such as image processing, where folks are more likely to make security mistakes and less likely to appreciate the need for an adversarial research mode. This spell DANGER, boys and girls. Some company consisting of few people, lots of venture capital, little experience and lots of tunnel vision is IMHO likely to resort to this law when researchers find a big hole in their breadwinning technology. I should add that watermark attack tools like unZign and StirMark are now used as benchmarks by developers of new schemes. It's only been, what, half a year since StirMark was created? A gaggle of watermarking papers already cite it, and include it in a standard volley of tests. These are not evil warez from Hell here. -Xcott ==- Xcott Craver -- Caj@niu.edu -- http://www.math.niu.edu/~caj/ -== "Also note that elecronagnetic theory proves that if you microwave a bar of Ivory soap it turns into a REAL MARSHMALLOW THAT YOU CAN EAT." -James "Kibo" Parry
