“…In VRAE methods, the remote server generates embedding room by modified some pixel values of the encrypted image directly. VRAE methods can be further grouped into three categories, i.e., data extraction in plaintext domain [19]- [23], data extraction in the cipher domain [24]- [30], and data extraction in both domains [31]- [34]. These VRAE methods achieve decent performances of RDH in encrypted image.…”

Typical reversible data hiding in encrypted image (RDH-EI) methods merely embed data in the encrypted domain, ignoring the requirement of the image owner for data embedding. To address this issue, this paper proposes a novel RDH-EI method with dual data embedding based on generalized integer transformation (GIT). The image owner first vacates embedding room, and performs data embedding before image encryption. After data encryption, the remote server utilizes the vacated room to further embed additional data into the encrypted image. The embedded data by the image owner and remote server can be extracted exactly, and the original image can be recovered losslessly. The experimental results prove the effectiveness of the proposed method. INDEX TERMS Reversible data hiding, encrypted image, generalized integer transformation, dual data embedding.

“…Data hiding is then performed with the use of a labelling strategy. It achieves a higher embedding capacity than most existing methods [22]- [27], [37], [38]. 2) We propose another RDHECI scheme based on modified AMBTC compression codes, M-AMBTC, where the parities of quantization levels are modified to be in homomorphism.…”

Recently, reversible data hiding in encrypted compressed images (RDHECI) has attracted more attention due to privacy information protection concerns. Meanwhile, AMBTC as one technique of lossy image compression that has lower storage costs and the simplicity in computation and is extensively used in many applications. Hence, this paper proposes an RDHECI scheme based on AMBTC, named O-AMBTC, to address privacy concerns. First, the original image is scrambled in a block-wise manner to generate the scrambled image which then is compressed by an AMBTC compression technique. Subsequently, the derived AMBTC compression codes are encrypted by using the methods of value modulation and stream cipher while the correlations between two quantization levels of AMBTC compression codes are retained and exploited to vacate redundant room to embed secret messages. Data hiding is then performed with the use of PBTL labeling strategy. In addition, another modified AMBTC compression code based RDHECI scheme, called M-AMBTC, is suggested to increase the ability to carry secret messages. In our dual approach, both the AMBTC-compressed image and the secret messages can be correctly recovered. Experimental results show that two proposed schemes are able to achieve average embedding rates as large as 0.6 bpp and 0.8 bpp when the block size is set to 2 × 2, respectively.

Importances of reversible data hiding practices are always higher in contrast to any conventional data hiding schemes owing to its capability to generate distortion free cover media. Review of existing approaches on reversible data hiding approaches shows variable scheme mainly focussing on the embedding mechanism; however, such schemes could be furthermore improved using encoding scheme for optimal embedding performance. Therefore, the proposed manuscript discusses about a cost-effective scheme where a novel encoding scheme has been used with larger block sizes which reduces the dependencies over larger number of blocks. Further a gradient-based image registration technique is applied to ensure higher quality of the reconstructed signal over the decoding end. The study outcome shows that proposed data hiding technique is proven better than existing data hiding scheme with good balance between security and restored signal quality upon extraction of data.
