 project  proj ect name: IMAGE STEGANOGRAPHY:

INTRODUCTION ; Steganography is the idea of hiding private or sensitive data or information within a image that appears to be normal and no one can find the difference between normal and encrypted image. Popularity of steganography has grown in recent year because of  the ability to more easily placing steganography data within images, audio files, etc. This project's goal is to investigate steganography by creating a system to write steganography data into image files and then send this image through secure and reliable network. I want to do this project by client server mechanism in which first a client encrypt some secret data into an image file and then sent it to the server through a secure channel. Then server will run an algorithm to decrypt hidden data and separate this data from original image.

MOTO:

The message encrypted in an image or any other file can be transmitted easily through internet. I want to write a java code to transmit encrypted message in an image file from sender I want to do this project by client server mechanism in which first a client encrypt some secret data into an image file and then sent it to the server through a secure channel. Then server will run an algorithm to decrypt hidden data and separate this data from original image.

TOOLS AND METHODS : I have searched about this project that what programming language should I used to do this !nd I find out python is the best choice for this. "ecause python is light weighted and very powerful language. !nd by using python implementing server client model is very easy and efficient.so I will use python as primary language for coding. The main problems in the Steganography fallow as# $ The si%e of data hidden $ &uality of image $ evel of data protecting $ The level of suspecting The problem in the hiding information is the si%e of data that user want to embed inside the image file. I will use east Significant "it (S") method for selenography.  ! pi*el consist on + bits for each the three -" color values (red, green, and blue).the change in last bit of each color is undetectable and if we change the last bit of each -" values then we will get bits free to put our secret data in it. Suppose we have + bits representing each of the three -" color values (red, green, and blue) at each pi*el. If we consider just the blue there will be  + different values of blue. The difference between //////// and ///////0 in the value for blue intensity is likely to be undetectable by the human eye. Therefore, the least significant bit can be altered (more or less undetectably).and same with the red and green will provide 1 bits of empty space to put data.
