“…Chaotic maps are highly sensitive to the initial values and parameters, which makes them difficult to predict without knowledge of the correct value of the initial value and parameter. Researchers have proposed optical image encryption algorithms using Logistic, Cosine, Rational, 2-D Lorenz, Baker, Arnold cat, Chen chaotic, Exponential, Umbrella, Tinkerbell, Gauss, Henon map, 3-cell CNN system, Mixed memristive chaotic circuit, Edge map and other chaotic maps [34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49]. For example, to generate the Tinkerbell map, the following equations can be used:…”

In the modern era, the secure transmission and storage of information are among the utmost priorities. Optical security protocols have demonstrated significant advantages over digital counterparts, i.e., a high speed, a complex degree of freedom, physical parameters as keys (i.e., phase, wavelength, polarization, quantum properties of photons, multiplexing, etc.) and multi-dimension processing capabilities. This paper provides a comprehensive overview of optical cryptosystems developed over the years. We have also analyzed the trend in the growth of optical image encryption methods since their inception in 1995 based on the data collected from various literature libraries such as Google Scholar, IEEE Library and Science Direct Database. The security algorithms developed in the literature are focused on two major aspects, i.e., symmetric and asymmetric cryptosystems. A summary of state-of-the-art works is described based on these two aspects. Current challenges and future perspectives of the field are also discussed.

This study presents a novel approach for encoding and decoding colour imagesby combining the Arnold Transform, Discrete Wavelet Transform (DWT),Singular Value Decomposition (SVD), and the fast walk Hadamard transform(FWHT) process. The encoding process involves using clusters of Arnold keysand wavelets, along with singular values of wavelet subbands. The specific calculationsof all wavelet subbands determine the number of Arnold keys and theparameters of the fast wavelet Hadamard transform. To evaluate the effectivenessand robustness of the proposed technique, the average squared deviationand the ratio of the peak signal power to the power of the noise are used. Theresults show that energy is conserved when employing fast Walsh Hadamardtransforms, and the encrypted image can be compressed effectively. Thus, thismethod offers a secure and efficient approach for transmitting colour imagesover both secure and unreliable communication channels.
