The encryption and decryption results: (a) encrypted color image for the first group of test images, (b) decryption of “Lena,” (c) decryption of “Liftingbody,” and (d) decryption of “Barbara”; (e) encrypted color image for the second group of test images, (f) decryption of “Cameraman,” (g) decryption of “Rice,” and (h) decryption of “Text”; and (i) encrypted color image for the third group of test images, (j) decryption of “Onion,” (k) decryption of “Peppers,” and (l) decryption of “Toyobjects.”
