“…To further improve the embedding rate, the PSNR will be reduced and more secret bits will be embedded using VE. Compared with other related methods including Wu et al [31], Shiu et al [29], and Chen et al [28], the proposed method has a better performance in terms of the embedding rate and PSNR.…”

“…After that, the data hider embeds secret bits into the encrypted signals by the additive homomorphism. To reduce data expansion, Shiu et al [29] adopted a difference expansion method to embed the message. Zhang et al [30] proposed a lossless, a reversible, and a combined data hiding scheme for ciphertext images, respectively, which were encrypted by a public key cryptosystem with homomorphic properties.…”

Compared to the encrypted-image-based reversible data hiding (EIRDH) method, the encrypted-signals-based reversible data hiding (ESRDH) technique is a novel way to achieve a greater embedding rate and better quality of the decrypted signals. Motivated by ESRDH using signal energy transfer, we propose an improved ESRDH method using code division multiplexing and value expansion. At the beginning, each pixel of the original image is divided into several parts containing a little signal and multiple equal signals. Next, all signals are encrypted by Paillier encryption. And then a large number of secret bits are embedded into the encrypted signals using code division multiplexing and value expansion. Since the sum of elements in any spreading sequence is equal to 0, lossless quality of directly decrypted signals can be achieved using code division multiplexing on the encrypted equal signals. Although the visual quality is reduced, high-capacity data hiding can be accomplished by conducting value expansion on the encrypted little signal. The experimental results show that our method is better than other methods in terms of the embedding rate and average PSNR.

“…In recent years, some RDH methods for encrypted images have been proposed. In general, these methods can be divided into three categories, that is, methods by vacating room after encryption (VRAE) [18][19][20][21][22][23][24], methods by reserving room before encryption (RRBE) [25][26][27][28], and methods based on homomorphic encryption [29][30][31][32][33][34]. In VRAE framework, the original signal is encrypted directly by the content owner, and the data hider embeds the additional bits by modifying some bits of the encrypted data.…”

An efficient method of completely separable reversible data hiding in encrypted images is proposed. The cover image is first partitioned into nonoverlapping blocks and specific encryption is applied to obtain the encrypted image. Then, image difference in the encrypted domain can be calculated based on the homomorphic property of the cryptosystem. The data hider, who does not know the original image content, may reversibly embed secret data into image difference based on two-dimensional difference histogram modification. Data extraction is completely separable from image decryption; that is, data extraction can be done either in the encrypted domain or in the decrypted domain, so that it can be applied to different application scenarios. In addition, data extraction and image recovery are free of any error. Experimental results demonstrate the feasibility and efficiency of the proposed scheme.

“…The basics of the proposed technique are to preprocess an image with the quality of various expansions before encryption of an image. This technique gives good payload and improves quality of image [11]. In the data transmission, security is the most significant and important issue over network.…”

Cryptography is necessary for the security of the data which may in the form of text, audio and video. In general Symmetric and Asymmetric cryptographical methods are used for the above purpose. In which all types of data is converted into the binary number system. Due to non availability of the cryptographical system, hackers may have hack the data. For the strong security, various researcher have used RSA cryptosystem which is widely used in the digital signature. In the present paper, an extension of RSA cryptography is well explained for the three variables. An implementation of the proposed RSA system for three variables is demonstrated through the implementation of the Wiener"s extension. Various theorems with proof are given in the paper and implementation is given on the Aadhaar card based ATM system.
