Timing-based active watermarking schemes are developed to trace back attackers through stepping stone connections or anonymizing networks. By slightly changing packet timing, thes...
Most of watermarking techniques are based on Wide Spread Spectrum (WSS). Security of such schemes is studied here in adopting a cryptanalysis point of view. The security is proport...
Buyer-seller watermarking protocols incorporate digital watermarking with cryptography, in order to protect digital copyrights and privacy rights for the seller and the buyer befo...
