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. This paper presents a comparison between the basic LSB technique which involves replacement of least significant bits in order to hide the colored message image behind the colored cover image, with the other technique for increased capacity of hiding information using an advanced LSB methodology wherein the bit replacement takes place in accordance to range specified for the color images. There have been many techniques for hiding messages in images in such a manner that the alterations made to the images are perpetually indiscernible. This paper proves experimentally that the technique for increased capacity of information hiding in LSB‘s method gives better performance in all the parameters and is a safe technique for embedding secret messages.
