“…The receiver employs the same local pixel-swapping process to recover the 2-bit information hidden in each block of the image E . Each block will be transformed into four different versions by using the four local pixel-swapping operations as referred to in Equation (9). Let us consider a marked block V from E .…”

Reversible data hiding (RDH), a promising data-hiding technique, is widely examined in domains such as medical image transmission, satellite image transmission, crime investigation, cloud computing, etc. None of the existing RDH schemes addresses a solution from a real-time aspect. A good compromise between the information embedding rate and computational time makes the scheme suitable for real-time applications. As a solution, we propose a novel RDH scheme that recovers the original image by retaining its quality and extracting the hidden data. Here, the cover image gets encrypted using a stream cipher and is partitioned into non-overlapping blocks. Secret information is inserted into the encrypted blocks of the cover image via a controlled local pixel-swapping approach to achieve a comparatively good payload. The new scheme MPSA allows the data hider to hide two bits in every encrypted block. The existing reversible data-hiding schemes modify the encrypted image pixels leading to a compromise in image security. However, the proposed work complements the support of encrypted image security by maintaining the same entropy of the encrypted image in spite of hiding the data. Experimental results illustrate the competency of the proposed work accounting for various parameters, including embedding rate and computational time.

“…In this technique, the data are embedded in mediums such as an image, videos, or audio. Apart from this, a hologram is another example of the cover medium used in RDH [ 9 , 10 ]. The crust of RDH is in extracting the embedded data and recovering the actual cover medium, both in a lossless manner [ 11 , 12 , 13 ].…”

In this paper, we propose an optical image watermarking scheme based on orbital angular momentum (OAM) holography. Multiple topological charges (TCs, l) of OAM, as multiple cryptographic sub-keys, are embedded into the host image along with the watermark information. Moreover, the Arnold transformation is employed to further enhance the security and the scrambling time (m) is also served as another cryptographic key. The watermark image is embedded into the host image by using the discrete wavelet transformation (DWT) and singular value decomposition (SVD) methods. Importantly, the interference image is utilized to further enhance security. The imperceptibility of our proposed method is analyzed by using the Peak Signalto-Noise Ratio (PSNR) and the histogram of the watermarked host image. To demonstrate robustness, a series of attack tests, including Gaussian noise, Poisson noise, salt-and-pepper noise, JPEG compression, Gaussian low-pass filtering, cropping, and rotation, are conducted. The experimental results show that our proposed method has advanced security, imperceptibility, and robustness, making it a promising option for optical image watermarking applications.
