Figure 5

Color image encryption and decryption histogram. Image (a) is displayed as a color house image, image (b) is a histogram of (a), image (c) is an encrypted image of (a), and image (d) is a histogram of (c). Image (e) is displayed as a color monkey image, image (f) is a histogram of (e), image (g) is an encrypted image of (e), and image (h) is a histogram of (g). Image (i) is a color map image, image (j) is a histogram of (i), image (k) is an encrypted graph of (i), and image (l) is a histogram of (k).
