Abstract
Steganography is the art of hiding a digital media with another digital media, it is very important to transmit a secret data from place to another because if any one intercept the data during the transmission he can't know if there is a data a data or not. This paper shows a new method to hide a secret data in an image without any bit change of the stego image that means the PSNR value between the original image and stego image equal to Infinity. The size of the secret message that can be hidden in the image is infinity or unlimited. This method based on generating a dynamic symmetric key between the sender and the receiver, it is used for encoding and decoding process and it is derived from the image and the secret message together.
Keywords
