- Abstract
Aimed at the insecurity of the digital produces, a DWT and DCT domain digital image blind robust watermarking algorithm based on independent component analysis (ICA) is proposed in this paper. The image is decomposed by DWT first, and low frequency sub-bands are performed by DCT again. Then, scrambled watermark is embedded in middle-frequency of DCT area. In the extraction procedure, ICA is applied to obtain the embedding watermark signal, without requiring the original image and any information about watermark. Then correlation analysis and restore scrambling are applied to get the watermark. Experimental results show thaa the algorithm is very robust to common attack operations such as adding noise, JPEG compression, filter and so on and has good performance.
