“…Generally, the histogram of a natural image is unevenly distributed which makes it easily detected by attackers during transmission. In contrast, the histogram of any secured image is uniformly distributed which makes it hard to detect by attackers during transmission [28,29]. Our simulations were conducted for three images and figure 11 shows that the histograms of the output images by the proposed compression-encryption method are uniform.…”

Traditional Compressive Sensing (CS) achieves both compression and encryption of digital data. However, most existing compressive sensing methods present some shortcomings, including weak resistance to chosen-plaintext attacks and heavy key management burden. To overcome these shortcomings, this work presents a new combination of CS with optical transformation for digital image compression and encryption. The proposed compression-encryption scheme utilizes the interesting properties of CS and permutation-diffusion techniques to reduce the image size and encrypt the image data. A novel Duffing Oscillator (NDO) is proposed, its dynamics is deeply analyzed, and its sequences are exploited to build a hardware-friendly measurement matrix for the CS process. This also contributes to reducing the total size of secret key sent to the receiving end. In addition, the final image compression-encryption output is obtained by applying one of the most significant optical encryption methods, namely Double Random Phase Encoding (DRPE). This contributes to further strengthen the security of the proposed scheme. Eventually, the experimental results imply that our scheme is effective in improving the resistance against various attacks, while guaranteeing good imperceptibility and reconstruction performance. It can then be employed in the information security communication field. Keywords: Privacy data protection, duffing oscillator, compressive sensing, double random phase encoding, security analysis.

“…Although the specific details of the key steps are not explicitly provided, it is presumed that the technique involves modifying the existing vision transformer framework to seamlessly integrate the secret key during image and model processing. By doing so, the proposed method intends to enhance the overall protection of sensitive data during transformations.In order to [10]meet the requirements of future photonic devices, it is necessary to have certain desirable properties such as low power consumption, high performance, and low threshold currents. Current modulation-based vertical cavity surfaceemitting lasers (CM-VCSELs) possess these characteristics and hold significant potential for optical secured communications in the next generation.…”

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.

Traditional visually meaningful image encryption (VMIE) works by embedding a secret image (SI) into a visually meaningful carrier image (CAI), thus achieving the dual protection of both data information and appearance features. However, the current VMIE algorithm still suffers from problems of reconstruction quality and transmission efficiency. To address these issues, this paper proposes an innovative VMIE algorithm that utilizes a newly designed two-dimensional hyperchaotic map, multi-parameter fractal matrix (MPFM) theory and compressive sensing. The proposed algorithm achieves dual protection of both the semantic information and appearance image data. First, a newly designed 2D infinite triangle folding map (2D-ITFM) is presented to generate a binary key-controlled measurement matrix to measure and compress a plain image (PI) to generate measured image (MI) and decrease the amount of transmission information. Next, based on the hyperchaotic map 2D-ITFM and MPFM, we present the inter-block scrambling (IBS) algorithm and intra-block synchronous sorting diffusion (IBSSD) algorithm, which are used to process the MI and generate SI. Then, the matrix encoding embedding (MEE) technique is utilized to hide the SI into the CAI to produce a visually secure cipher image (CII). Finally, the experimental results demonstrate that our scheme is effective in improving the anti-attack ability while guaranteeing good imperceptibility and reconstruction performance. This scheme can be employed in the field of information security communication.
