“…The results show that medical images still maintained a good image quality at a fixed embedding rate. Table 3 compares the proposed method with the 2D matrix methods of Chang et al [15], [16], Kurup et al [17], Lee and Wang [19] and Lee et al [20], and Xia et al [22]. The embedding rate of the proposed method is 2.25 bpp.…”

“…The proposed method also achieved an embedding capacity of 2.25 bpp and an average PSNR of 43 to 44 dB for nine standard test images. Moreover, the proposed method showcased better imperceptibility than methods [23] and [24] and the ER exceeded than methods [17], [19], [20], and [22] by more than 0.25 bpp. Therefore, the proposed method has more advantages compared to the previous methods.…”

Medical records are extremely sensitive information and may cause a violation of patients' rights if the data is captured or altered. Such data requires uncompromising security during transmission or when the data is stored in medical datacenters. The most commonly used procedure is to hide sensitive information inside a cover medium without incurring any increase in data size or computational overhead. Even though many steganography techniques have been proposed in recent years, only a few have addressed issues related to protecting medical data. In this paper, we proposed a data hiding method based on magic cube generated using magic matrix. In the proposed method, 9 bits of secret data were embedded in each group of 4 pixels using secret keys that scattered values in the square template to make it more unpredictable. Experimental results showed that the proposed method achieved an embedding capacity of 2.25 bpp and an average PSNR of 44 dB outperforming previous methods.

“…It achieved a payload of 1.5 bpp with a high visual quality of the stego-image (about 49.42 dB). Kurup et al proposed a data hiding scheme based on an octagon-shaped shell to embed four secret bits in the cover pixel pairs and achieved a payload of 2 bpp [15]. Subsequently, Leng improved the scheme of Kurup et al by using a regular octagon-shaped shell to embed five secret bits in the cover pixel pairs and realized a payload of 2.5 bpp [16].…”

The exploiting modification direction scheme is a well-known data hiding method because of its high payload and low distortion. Its most criticized drawback is that the secret data must be converted to a non-binary numeral system before the embedding procedure. To overcome this drawback, one study proposed a turtle shell-based scheme for data hiding, in which a reference matrix was constructed based on a hexagon-shaped shell to embed three secret bits into each pixel group of a pair of pixels of the cover image. In a subsequent work, the embedding capacity was increased by using an octagon-shaped shell instead of a hexagon-shaped shell in the reference matrix. The above scheme was extended by utilizing a regular octagon-shaped shell in the reference matrix to reduce the distortion of the worst case. In another approach, the payload of the octagon-shaped-shell-based data hiding scheme was maximized by searching for the appropriate width and height of the octagon. In this study, we generalize the data hiding scheme based on an octagon-shaped shell so that the above-mentioned four schemes can be regarded as specific cases of the proposed method.
