“…At the same embedding rate, the PSNR of our scheme is higher than that of the literatures [22], [24]- [26]. When the embedding rate is small, the PSNR in [28] is higher than our paper. This is because the absolute difference in [28] is sorted so that the pixels near the peak value are embedded first.…”

“…In the following experiments, we use experimental results under T = 3 to compare embedding distortion with other state-of-the-art works. The proposed scheme is compared with the other state-of-the-art works of Shiu et al [22], Zhang et al [24], Xiang et al [25], [26] and Xiong et al [28] using four test images (in Fig. 5).…”

“…Each additional data is embedded into two pixels in [26] and [27] so that the maximum embedding rate is only 0.5 bpp. In [28], Xiong et al proposed two additional data are embedded into groups of three pixels, which means the embedding rate can increase to 0.67 bpp in the best case. Considering above algorithm with VRAE, this paper proposes a separable reversible data hiding scheme in homomorphic encrypted domain by using NTRU instead of Paillier or DGHV (Dijk, Gentry, Halevi and Vaikuntanathan) and so on, which are the following reasons.…”

“…3) Each additional data is embedded into two pixels in [26] and [27] so that the maximum embedding rate is only 0.5 bpp. Two additional data are embedded into groups of three pixels in [28], which means the embedding rate can increase to 0.67 bpp at most. Generally speaking, T additional data are embedded into groups of a reference pixel and T adjacent pixels, which the embedding rate can be calculated as T /(T + 1), T ∈ {1, 2, 3, 4}.…”

Data Hiding in Encrypted Domain Based on Encryption Process''. Through excavation and effective use of redundancy in the encryption process, we compromise the information hiding technology and encryption technology, construct the theoretical model of the fusion of cryptography and information hiding technology, and design secure and efficient reversible information hiding methods. ABSTRACT NTRU (Number Theory Research Unit) has the characteristics of resistance to quantum computing attacks, fast encryption and decryption, and high security. It is very suitable for wireless confidential data networks and authentication systems. Combined with reversible data hiding technology, a separable reversible data hiding scheme in homomorphic encrypted domain based on NTRU is proposed. The image owner directly divides the cover-image into groups of a reference pixel and T adjacent pixels. Then, the grouped image is encrypted by NTRU. Finally, the encrypted image is uploaded to the data hider. The encrypted image is divided into groups by the same grouping method as the image owner. After that, the data hider calculates T absolute differences of adjacent pixels in each group to obtain histogram of the absolute differences. The additional data can be embedded into the encrypted image by shifting histogram of the absolute differences. After receiving the encrypted image with hidden data, the receiver can either use the data hiding key to directly extract the additional data from encrypted domain to obtain the encrypted image, or use the private key and data hiding key to extract the additional data from plaintext domain to get the cover-image. Experimental results show that our scheme has higher security and better embedding performance comparing with other state-of-the-art works. INDEX TERMS Reversible data hiding, encrypted domain, public key cryptosystem, homomorphic property, number theory research unit (NTRU).

“…Adoption of binary tree with discrete labeling approach was also proven to improve the performance of reversible data hiding approach [16]. Homomorphic encryption is also claimed of offering better encryption performance over multimedia data [17]. Jiang et al, [18] have used encryption of the bitstreams using least significant bits over a mesh model for performing reversible data hiding.…”

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.
