“…The decoder side by further exploiting the spatial correlation using a dissimilar estimation equation and side match technique. For both methods in [10] and [11], decrypting image and extracting data must be jointly executed. Recently, Zhou et al [12] proposed a novel RDH-EI method for joint decryption and extraction, in which the correlation of plaintexts is further exploited by distinguishing the encrypted and non-encrypted pixel blocks with a twoclass SVM classifier.…”

Abstract:The following paper proposes a novel scheme of data hiding in encrypted images based on lossless compression of encrypted data. In encryption phase, the original content is encrypted into images. As majority of the encrypted data is kept unchanged, the quality of the decrypted image is satisfactory. In the receiver phase, the data is successfully extracted from the image with the help of a public key. The receiver can further recover the original plaintext image without any error.

“…The proposed method is separable for data extraction and image recovery, the same as the methods [11] and [12]. Errors may happen in the recovered image depending on the block size when using the methods [9] and [10], while the proposed method can perfectly recover the original image on the receiver side. Another important feature in Table 2 is whether the RDH method needs pre-processing for reserving embedding room for data hiding in encrypted image.…”

“…In [9], Zhang divides the encrypted image into blocks, and embeds one bit into each block by flipping 3 LSBs of the half of the pixels in the block. Hong et al [10] provided an improved version of Zhang's method, by exploiting the correlation of the border of neighboring blocks, and using the side-match scheme to achieve a lower error rate. These two methods can be realized because of the spatial correlation in the decrypted image.…”

Abstract. This work proposes a novel scheme of separable reversible data hiding for encrypted image using histogram modification. After the original image is encrypted by the sender, the data-hider embeds the secret message into the encrypted image by a histogram modification and n-nary data hiding scheme. On the receiver side, the secret message can be extracted by the embedding key, and the original image can be totally recovered using both the embedding key and the encryption key. If the embedding key is unavailable for the receiver, the original image can still be approximately recovered using the encryption-key. This separable method does not require the sender to reserve embedding room by himself, and can perfectly recover the original image. Compared to the existing reversible data hiding methods for encrypted images, the proposed method largely improves the embedding capacity.Keywords: Reversible data hiding. Information hiding. Image recovery IntroductionReversible data hiding (RDH) is a technique that embeds secret data into the cover, like military or medical images, by slightly modifying the data of the cover; and on the receiver side, the original image can be losslessly recovered [1,2]. Many RDH methods have been proposed for digital images, such as the general RDH framework by redundancy compression [3], the difference expansion (DE) method [4], the histogram shifting (HS) method [5], and so on [6][7][8]. Traditionally, these methods are useful for embedding data into the images that are open to the data-hider. However, in some scenarios, the owner of the cover is unwilling to show the information of the original image to the data-hider. For example, to protect the patient's privacy, content of the medical image might be unavailable for the technician who embeds the information into the medical image. These applica-1 Z. Qian ()
