Steganography (Encoding text and Hiding it within image)

Abstract

The simple abstract we can talk about in this project is about the idea of information security has became very important thing in our life, so we can not depend only on data or information encryption but hiding it too which is called (Steganography).So it is a method in which we hide an information inside an other so the real information or data can not be seen. The information we want to hide in this project is a text message to be hidden in a picture which is a BMP (Bit Map) format which is simple. We will use the programming language (Visual Basic) to do this job, Hiding a text message in a picture needs on the other hand getting the image back from the picture so the program will contain this operation too.The data of the BMP picture will be replaced by the hidden text message so it may cause distortion in that place therefore the message must be distributed all over the picture so the distortion would be reduced. In the future we can hide another type of data inside another type of carrier (out world data) such as hiding text inside a voice file.
