文摘The fractional logistic map holds rich dynamics and is adopted to generate chaotic series.A watermark image is then encrypted and inserted into the original images.Since the encryption image takes the fractional order within[0,1],it increases the key space and becomes difficult to attack.This study provides a robust watermark method in the protection of the copyright of hardware,images,and other electronic files.
