“…The presented technique for security of color image data are compared with existing techniques of Liu et al (Liu et al, 2015), Prasad et al (Prasad, Kumar, & Choudhary, 2012), Singh et al (Singh, Kumar, & Singh, 2009), and Guo et al (Guo, Liu, & Liu, 2010). Liu et al (Liu et al, 2015) proposed color image security by using phase-only encoding in Fresnel domains, which provides security of color images in the optical domain only; the experimental results of the technique (Liu et al, 2015) are given in Figure 10 and Figure 11.…”

“…Liu et al (Liu et al, 2015) proposed color image security by using phase-only encoding in Fresnel domains, which provides security of color images in the optical domain only; the experimental results of the technique (Liu et al, 2015) are given in Figure 10 and Figure 11. The experimental results of this cryptosystem (Liu et al, 2015) indicate that the security of color image data depends on keys only in the optical domain. Prasad et al (Prasad et al, 2012) give color image encoding using a fractional Fourier transform associated with a wavelet transform, which provides security of color image data in the frequency domain only.…”

“…Meanwhile, various optical transforms such as fractional Fourier transform, Fresnel transform, gyrator transform, and other means have been applied, where additional parameters can be considered the secret keys to enhance the level of security [16][17][18][19][20][21][22][23][24][25][26][27][28]. Due to its novel physical characteristics such as the complexity of its optical parameters, the ghost imaging technique can provide a promising alternative for the optical cryptosystem [29][30][31][32][33].…”

“…[19], Sui et al modified the multiple-image encryption scheme using the chaotic technique, in which the security is considerably enhanced. In addition, as a special case of multiple-image encryption, color image encryption has also developed rapidly [20,21]. However, Peng et al [22,23] claimed that traditional linear cryptosystems could be vulnerable when confronted with potential attacks.…”
