Objective :
Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity.
In this software we can hide information in an image
file. The information is carefully encrypted and hidden so you cannot easily find it.
Methodology :
For each bit in the message,this program picks a random pixel in the image and a random red, green, or blue component in that pixel. It then sets the least significant bit in that component to the bit value it is encoding.These changes are so small they are almost impossible to detect. In a photographic image, you will not be able to tell the difference just by looking.The program uses a password to initialize the random number generator Rnd. When you decode the message, the program initializes the random number generator using the same seed so it produces the same series of pseudo-random numbers.
Outcome:
This program will hide a message in an image ,so only the sender and receiver know it's there.While everyone may see the public data, they won't know the secret message is present.Data will be Secured.
