Steganography is a technique where, the secret message is embedded into an image called cover image, and then sent to the receiver. A data hiding scheme by improved LSB substitution is proposed. In simple LSB technique only single LSB bit is used from cover image to hide data bit. But in improved LSB technique, in proposed system, three bits from a color pixel used to hide data bits. Before embedding data bits into color image first encrypt the image and then compress encrypted image for additional space. At the receiver end when content owner receives this stego image they can extract the hidden data bits and recover the image.
