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