An Image Encryption Scheme of Logistic Modulation Using Computer-Generated Hologram and Chaotic Map

Figure 6

Test of robustness against noise attack and occlusion: (a) hologram without noise, (b) 1% Salt and Pepper noise on hologram, (c) 1.5% Salt and Pepper noise on hologram, (d) encrypted image, (e) 0.6% data loss on (d), and (f) 2.44% data loss on (d). The second row shows their corresponding decrypted images.
