Abstract :
A digital watermarking algorithm based on wavelet transform and chaotic encryption is proposed in this paper. First, the watermark image is pre-processed by scrambling with Arnold transform, then the host image is decomposed by wavelet transformation combining with the characteristics of watermarking algorithm. Experimental results show that using this encryption algorithm has a good encryption effect, and have good robustness.
