On the Secrecy of Timing-Based Active Watermarking Trace-Back Techniques
Timing-based active watermarking schemes are developed to trace back attackers through stepping stone connections or anonymizing networks. By slightly changing packet timing, thes...

Image quality monitoring using spread spectrum watermarking
An improved blind image quality assessment scheme that is based on the Watson's just noticeable difference (JND) modulated spread spectrum watermarking, is proposed. For the ...

An SVD-based audio watermarking technique
We present a non-oblivious, extremely robust watermarking scheme for audio signals. The watermarking algorithm is based on the SVD of the spectrogram of the signal. The SVD of the...
