An improved attack analysis on a public-key spread spectrum watermarking

We analyze the fingerprinting method in [1] and suggest attacks that are better than the ones presented therein. To do this, we observe and use some extra information available in the system. Selection of different attack channel distortion constraints are also discussed. See [2] for various recently proposed attacks on spread spectrum fingerprinting systems for private watermarking.
