This chapter presents a robust and secure framework for multimedia security using digital watermarking. In the proposed scheme, a cover image is transformed into frequency domain based on all phase discrete bi-orthogonal transform (APDBT) followed by singular value decomposition. A gray-scale watermark is then embedded by modifying the singular values. For watermark extraction, a new procedure based on dynamic stochastic resonance (DSR) is employed. The proposed DSR based extraction effectively utilizes the noise introduced during the attacks to enhance the robustness and authenticity of the watermark. A detailed experimental analysis is finally conducted to demonstrate the robustness and efficiency of the proposed scheme against a variety of attacks.read more
