A Novel Image Steganography Algorithm based on Digital Signature Security by LSB

The digital signature authentication scheme is a kind of sender-receiver protocol; the sender generates the signature and inserts it into the original image as a stego-image. The receiver extracts the signature and decode received image at the same time. If the signature and the stego-image match, the received image is thought to be authentic.
