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.eninfo:eu-repo/semantics/closedAccessDiscrete Fractional CalculusImage EncryptionWatermarkLetter21688088310.1631/FITEE.2000133
