ENCODING AND DECODING HIDDEN MESSAGES IN IMAGES USING STEGANOGRAPHY

Abstract

Visual Cryptography is a technique to share secret code in the form of images. Steganography is usedto encrypt these images into hidden codes which in earlier times is used as a mode of communication in the time of war. These hidden codes have their way of decryption, sharing images multiple times can decrypt these images. The encryption in these images is done in pixels so that it won’t be visible to the naked eye. The small changes in these images can be only visible by superimposing. After superimposing we can not recoverthe original image because of contrast and expansion in pixels of the image. The visual form of steganography is the safest form that is present nowadays. In this paper, we will know how we can encrypt this image in hidden form using cipher text and steganography and prevent itfrom being disposed of by the naked eye
