Abstract: |
A digital watermarking algorithm by dual scrambling with Arnold transform and chaotic encryption in Wavelet Transform Domain was proposed. Firstly, the digital watermarking was scrambled randomly by Arnold transform, and then encrypted by logistic mapping. The encrypted watermarking was embedded into low frequency band. The process of watermarking extracted is the inversion of the process of watermarking embedded. Finally, the watermarking extracted was obtained after the anti-Arnold transformation. The experiments indicate that the algorithm not only enables the watermarking to have very good invisibility, but also makes the watermarking has very good robustness to the general image attacks, such as scaling, rotation, cropping, noise, filter, JPEG compression and so on.
