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 i...

In this work, we consider the ISS (improved spread spectrum) watermarking [1] framework, and propose a generalized version of it, termed “Generalized Improved Spread Spectrum”...

We present a set of watermarking techniques for effective covert communication over an audio signal carrier. Watermark robustness is enabled using: (i) redundant spread-spectrum fo...
