Data Security Using Image Steganography And Weighing Its Techniques

Abstract Steganography is the art of covering secret and confidential information within a carrier which could be an image file video file or audio file. It is a technique which provides invisible communication since an image file which has the secret information embedded within it is delivered to the receiver instead of the secret information itself. The focus of this paper is to provide immense understanding of the Image Steganography technique - its history advantages over cryptography process model and comparison of its techniques.
