Fibonacci Transformation and Its Applications in Digital Image Watermark

A digital image scrambling method based on Fibonacci transformation is proposed. By considering its favorable property of uniformity, this paper tries to present a definition of the image scrambling effects and to compare the scrambling effects of Fibonacci transformation with those of the Arnold transformation. The experimental results show that Fibonacci transformation is better than Arnold transformation. The application of Fibonacci transformation in image watermark is also considered. The watermarking embedding algorithm is robust to some anti_attack tests.
