Enhanced Text and Image Security Using Combination of DCT Steganography, XOR Embedding and Arnold Transform

Abstract

In this paper present the enhanced text and image security using the combination of hybrid enhanced model using the DCT Steganography, XOR embedding and Arnold transform techniques. In this first hide the text data into the secret image using the DCT Steganography technique and get the stego image. After getting the stego image embedded Stego image with cover image using the XOR embedding technique and get the embedded image. Now after getting the embedded image calculate the MSE and PSNR values. For better hiding low MSE and high PSNR value is required. In proposed work get the low MSE and high PSNR value then previous work done. After getting the MSE and PSNR value apply the Arnold transform on the embedded image and get the encrypted image that is totally differ than all the images. After getting the embedded image calculate the entropy of the proposed technique. Using proposed technique multiple layer of security provides to the text data and secret image and also provide the security of the cover image using the Arnold transform.
