Perceptual watermarking of non i.i.d. signals based on wide spread spectrum using side information
The theoretical foundations of data hiding have been revealed by formulating the problem as message communication over a noisy channel, i.e. the host document. In light of this de...

Robust Covert Communication over a Public Audio Channel Using 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...
