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.
