Image Steganography: A Review

Abstract: In the recent years, the security related to data over the internet has become a major issue. In order to solve the problem, two main techniques are used, first is cryptography and second is Steganography. Both are used for data security purpose. Cryptography changes the form of the data and Steganography completely Conceals its presence from the users, except the intended receiver. In this paper, a technique is used which combines these two methods to provide a more efficient and effective result. Therefore different cryptographic algorithms are compared on the basis of Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR)

Keywords: Steganography, Visual Cryptography, Steganography Techniques, Stego Image.
