Efficient and Secure Online Transaction Using Steganography

Abstract

The online transactions can be made secured by using stegnography. Steganographic application includes covert communications between two parties whose existence is unknown to a possible attacker and whose success depends on detecting the existence of this communication. In general, the host medium used in stegnography includes meaningful digital media such as digital image, text, audio, video, 3D model. A large number of image stegnographic algorithms have been investigated with the increasing popularity and use of digital images. We weave the texture synthesis process into Steganography to conceal secret messages. In contrast to using an existing cover image to hide messages, our algorithm conceals the source texture image and embeds secret messages through the process of texture synthesis. This allows us to extract secret messages and the source texture from a stegno synthetic texture. Embedding capacity that is proportional to the size of the stegno texture image, a steganalytic algorithm is not likely to defeat our steganographic approach and the reversible capability inherited and provides functionality which allows recovery of the source texture. verified that it can provide various numbers, produce a visually plausible texture images, and recover the sourcetexture.
