Abstract
We propose the use of random wavelet packet decompositions as a way to increase the security of watermarking systems against unauthorized removal attacks. Experimental attacks based on coefficient quantization show that using a secret key-dependent subband structure to hide the watermarking domain significantly increases the watermark correlation under an attack as compared to a classical pyramidal wavelet watermark.
