New Solution for Password Key Transferring in Steganography Methods

One of the methods introduced for establishing hidden communication is steganography. One of the problems in these methods is the security of transferring password key used for steganography between sender and receiver of secure data. In this paper a new method is proposed for solving this problem using CAPTCHA method. In this method the password key is drawing in the image and the data are hidden in the image by this password key. So the human receiver can recognize the password from the image and extract the data from the image using this password, but a computer program cannot do above operation. By this method the user does not need to memorize any password for extracting the data.
