At present, there has been much focus on information hiding because it acts as an alternative to secure communication. Secret content is embodied in an image using various image embodiment techniques, with the least significant bit (LSB) substitution being one of the preferred strategies. Asserting the originality and quality of the content embodiment is equally challenging. A scrambling mechanism using a Sudoku scheme is applied on all red, green, and blue layer blocks of the image. The image layers are devised into blocks, and over the blocks unique scrambling procedures are applied to acquire the scrambled image. The scrambled image is then exposed to the confidential stream embodiment using the traditional LSB substitution scheme by following the chess game-based queen tour traversal pattern for locating the pixels. After the embedding process, the scrambled image is fragmented into blocks, and the exact descrambling of the blocks is performed to get back the image, which visually resembles the original image called the stego image. The stego image gets split into blocks at the receiver end to apply exact scrambling on the corresponding blocks, and using the queen tour pattern, the secret stream is to be extracted. As a result of the experiments, it is found that the projected approach is unlikely to be very predictable and unique in its patterns.

Stochastic computing is a relatively new approach to computing that has gained interest in recent years due to its potential for low-power and high-noise environments. It is a method of computing that uses probability to represent and manipulate data, therefore it has applications in areas such as signal processing, machine learning, and cryptography. Stochastic steganography involves hiding a message within a cover image using a statistical model. Unlike traditional steganography techniques that use deterministic algorithms to embed the message, stochastic steganography uses a probabilistic approach to hide the message in a way that makes it difficult for an adversary to detect. Due to this error robustness and large bit streams stochastic computing, they are well suited for high capacity and secure image steganography. In this paper, as per the authors’ best knowledge, image steganography using stochastic computing based on linear feedback shift register (LFSR) is proposed for the first time. In the proposed technique, the cover image is converted to stochastic representation instead of the binary one, and then a secret image is embedded in it. The resulting stego image has a high PSNR value transmitted with no visual trace of the hidden image. The final results are stego image with PSNR starting from 30 dB and a maximum payload up to 40 bits per pixel (bpp) with an effective payload up to 28 bpp. The proposed method achieves high security and high capability of the number of stored bits in each pixel. Thus, the proposed method can prove a vital solution for high capacity and secure image steganography, which can then be extended to other types of steganography.
