Semi-Fragile Image Watermarking Method Based on SVD and Block DCT
With the certification of the integrity of the multimedia content, the solutions are mainly concentrated on fragile digital watermarking technology. This paper present a semi-fragile watermarking algorithm based on SVD and sub-block DCT. The watermarking signals are embedded into the second biggest singular values of the image. Watson model is used to control the robustness of embedding. Experiments demonstrate that the algorithm meets the basic goals of semi-fragile watermarking: imperceptible, blind detection, distinguishing legitimate distortions from illegitimate ones, and the algorithm has some practical use.
