发帖数: 34 | 1 Digital watermarking is the best way to protect intellectual property from
illicit copying.

Why is it so difficult to find a needle in a haystack? Because of the size of
the needle relative to the size of the haystack. Also, because once the
needle falls out of your hand, it is not predictable where it will land in
the haystack. Both principles -- inconspicuousness and randomness -- help
conceal information in digital watermarks to protect intellectual property of
multimedia documents. |
