Yaping Lin · Dianzi xuebao · 2008
Robustness is the key problem in digital watermarking.A robust watermarking method based on JADE algorithm is proposed.In the algorithm,watermark is embedded by iterative blending,which guarantees that the watermark has better invisibility and robustness,then regards mixed image as one observed signal,watermark information as the other observed signal.Finally,blind source separation JADE algorithm is adopted to detect the watermark without precise location.The theoretical analysis and simulation results show that it has stronger robustness.
