E-Commerce or Electronic commerce is the buying and selling of goods and services in which any commercial transactions through wireless electronic devices such as hand-held computers (tablets), mobile phones or laptops is conducted anytime & anywhere via Internet technology. But, E-Commerce transactions or services are suffered by many attacks such as Man in the Middle attack, eavesdropping attacks, and etc. due to the lack of secured security infrastructure. Here, data security is one of the ways to keep the confidential information secure through E-Commerce transactions. In this connection, we have proposed an optimal and efficient data security with the combination of Elgamal cryptosystem and LSB image steganography technique for E-Commerce. In our proposed work, at the merchant side, Elgamal encryption technique is used to protect sensitive information during E-Commerce transactions from intruders and LSB image steganography process is also applied to hide generated Elgamal encrypted data and produce a stego-image (steganography image). Then, DCT (Discrete Cosine Transform) technique through autoencoder is imposed on stego-image to make an optimal image to increase the throughput of the work. After that, the produced optimal image with cipher text is sent to the customer end. At the customer end, first, stego-image is extracted from the optimal image using LSB retrieval process. Then, Elgamal decryption process is used to retrieve the original data and secure the E-Commerce transactions in efficiently. Based on the experiment, we have plotted the performance metrics such as MSE, PSNR and SSIM on the work and entropy of the optimal image is also calculated with respect to the sample image. Thereby, a high level performance metrics is obtained in our proposed work.

This work presents a new asymmetric data hiding technique that hides a variable number of secret message bits in the discrete cosine transform (DCT) coefficients of a cover image using a modular distance technique. Prior to data hiding, the proposed framework transforms a cover image from a spatial domain to various frequency coefficients using DCT. The DCT coefficients are arranged in two groups: one with low-frequency coefficient, and the other with the medium and high-frequency coefficients. The medium and higher frequency coefficients are processed for variable data hiding asymmetrically. The proposed technique hides variable sets of secret information bits in different coefficients. The variation in hidden secret information is maintained using a key developed based on the modulo of distance of a coefficient from the reference point. The same key is also used to retrieve the confidential information at the receiver ends. The results reveal that the presented framework does not create any visually significant distortion, and thus the hidden information does not attract the human visual system (HVS). The technique also results in high data hiding efficiency.

“…Plain text is the text which has the original message or data which is not encrypted and the ciphertext is the text which is ready to be used after the encryption of the message. A key is required for both the encryption and decryption of the data or message [15][16][17][18][19][20].…”

Steganography is the science and art of secret communication between two sides that attempt to hide the content of the message. It is the science of embedding information into the cover image without causing a loss in the cover image after embedding.Steganography is the art and technology of writing hidden messages in such a manner that no person, apart from the sender and supposed recipient, suspects the lifestyles of the message. It is gaining huge attention these days as it does now not attract attention to its information's existence. In this paper, a comparison of two different techniques is given. The first technique used Least Significant Bit (LSB) with no encryption and no compression. In the second technique, the secret message is encrypted first then LSB technique is applied. Moreover, Discrete Cosine Transform (DCT) is used to transform the image into the frequency domain. The LSB algorithm is implemented in spatial domain in which the payload bits are inserted into the least significant bits of cover image to develop the stego-image while DCT algorithm is implemented in frequency domain in which the stego-image is transformed from spatial domain to the frequency domain and the payload bits are inserted into the frequency components of the cover image.The performance of these two techniques is evaluated on the basis of the parameters MSE and PSNR.
