Discrete fractionalwatermark technique
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 robustwatermark method in the protection of the copyright of hardware, images, and other electronic files.
