Abstract
The present paper describes confusing attacks to two public key watermarking schemes: transformed-key scheme and eigenvector scheme. In the attacks, noises are constructed from the public information and embedded into watermarked signals so that the detectors report no watermark all the time. The simulation experiments demonstrate that the attacks are viable.
