A Steganography Algorithm and Cryptography Techniques for Hiding Image

Zanbaq Hekmet Thanon

Abstract: Steganography can be defined as the procedure of hiding a type of communication medium (i. e. text, audio or image) inside another type of medium. This paper will be discussing (Proposed system, utilizedforhiding and extracting the information. The Proposed system embeds a text within an image. Each of the sender and the receiver dont need exchanging any information prior to using the system, therefore, it can also be said that the system is purely steganographic. This paper discusses producing a stego-image so that the embedded message cannot be perceived by a random observer but can be noticed easily by the intended receiverthatknowsthe way of extracting the message. Proposed system has the goal of preventing the detection of a secret message. It is a technique to embed a text inside harmless cover-image (we used GIF, JPG and BMP image formats), and produce the stego-image (BMP image format) without making any visible changes to it. We can check the histogram for each of the cover and stego-images to verify if there is any different between them. The implementation results via MATLAB ver.8.1 package
