Abstract :
Watermarking provides an efficient method for copyright protection.this paper discusses the digital watermark technology which is based on Arnold and wavelet transform..After the Arnold transform of embedded watermark information ,then embeds it into host gray images with discrete waelet transform. Emulational experiments are done in Matlab,Experimental results demonstrate that this watermarking algorithms have better effect : The watermark is invisible and robust against kinds of classical attacks.
