Abstract
This paper presents a watermarking algorithm based on the Angular point detection in the wavelet domain. Vector graphics through the corners on the analysis of characteristics to obtain the outline of the image area. The host image by four wavelet transform to obtain frequency sub-image at all levels of the coefficient matrix. It treated the original watermarking signals using a periodic Arnold scrambling, then the scrambled signals no longer had the periodicity during the recovery. Scrambled watermark encrypted by a chaos sequence generated by Lorenz chaotic system, embedded into the host image. The experiments show that this paper presented algorithm in various attacks against the image has good robustness.
