Actually this would be weird. Suppose digital cameras had to be fitted with a watermark detection system. Suddenly, we have lost a much more fundamental fair use right -- the right to include copyright material as an incidental part of a photograph. If I took a photograph of a street scene, there would be huge amounts of copyright material in it. The design of people's clothes would be copyright, the architects would have rights in the design of the buildings, billboard images would be copyright, and so on. I can't think how you could embed a watermark in the design of a building, but in theory it could be possible to do so with a billboard image. What happens then, will the camera refuse to take the photograph? -- Pete --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
