The dual-image information hiding method has received considerable research attention on account of its high hiding capacity and favorable stego-image quality. The dual-image hiding technology encodes secret data across two images, requiring both stego-images to recover the correct secret data. Many factors affect the embedding capacity and image quality of the dual-image hiding method, including the nature of the hidden data, the block size, and the method by which pixels are modified. This study analyzes and encodes secret data, while controlling the degree of pixel distortion using two parameters-NC and MXD to improve the image quality. The NC parameter controls how many codes are used to re-encode a secret symbol, which is used to control the number of code combinations. MXD specifies the maximum distortion of each code combination and is used to limit image distortion. To improve the effectiveness of the encoding, a pair of digital combinations was assigned according to the frequency of the secret numeric messages. A highly uniform secret message was encoded using a small distortion code. Subsequently, the code was concealed within the cover image, generating two stego-images. The experimental results indicate that the proposed method achieved not only a better embedding rate but also a greater image quality compared with previous methods. In particular, with regard to the smooth image, the image quality of the stego-image was higher than 64.27dB when the proposed scheme was applied. Furthermore, this study utilized many steganalytic technologies to validate the security of the proposed scheme.

In recent years, the reversible data hiding (RDH) based on dual stego cover is developing rapidly because of its high capacity and low distortion. For image case, however, two consecutive images of the same image will draw the attention of adversaries during transmission. In this paper, we propose a high-capacity RDH scheme using dual-channel audio, by exploiting the natural dual-channel property of the stereo audio. Specifically, we first convert secret message into novenary digits, which could increase the embedding capacity. Then, the magic matrix is used to embed the secret digit into a single-channel audio to generate two single-channel stego-audio. Finally, the two single-channel stego-audio is combined as a convention dual-channel audio. Extensive experiments have demonstrated that our proposed method could significantly boost the stego quality (the SNR is improved by 16% on average), when comparing with the state-of-the-art methods.

“…To enhance the hiding capacity, Lu et al [20] proposed a center folding strategy that can embed a set of K secret bits into a pair of pixels. In addition, the strategy can The current methods in the spatial domain can be classified mainly into five types, i.e., the compression method [4], difference expansion [5], prediction [6][7][8][9][10][11], histogram [12][13][14], and dual-image [15][16][17][18][19][20][21][22][23]. In 2002, Celik et al [4] proposed a compression-based hiding method that quantified the pixels in the image and recorded the values of remainders, which were used as recovery information.…”

Abstract:Compared with traditional hiding methods, dual-image reversible data hiding methods have a higher embedding rate and a better quality stego image. Also, this is a special case of secret sharing, because secret data cannot be extracted from any stego image. In the literature, the frequencies of occurrence of secret data were used as reference information for data encoding, in which most digits were transformed into smaller ones. The encoding strategy can effectively decrease the modification level of the pixel. However, only limited literature has analyzed the relationship between the adjacent secret data. In this paper, we proposed an exclusive-or (XOR)-based encoding method to convert the neighboring values, thereby reducing the distortion. Since there are significant similarities between the two stego images and the original image, the first stego image is stored on an unmanned aerial vehicle (UAV) to avoid a hacker's interception attack. The second stego image on the UAV is sent to the command station. After completion of the UAV mission, the proposed method extracts the secret data from the two stego images to identify whether the second stego image has been tampered with.
