A Proposal of Steganography Algorithm by Random Image Transformation

Abstract

The rapid developments in communications systems and the Internet have led to propose a new hiding algorithm to transfer the image, text, or voice over the Internet and network. The image is considered a cover to hide the massage by using a secret random key. The secret key is 9×9 matrix and then random elements are selected to make inverse matrix. The inverse matrix is multiplied by one–dimensional matrix, resulting in hidden images. This algorithm keeps the images secret during transmission through network. Such a process is known as random image transformation and is regarded as a reliable means of concealment.The results obtained from the proposed algorithm depend on the cover image. The secret key is generated so that it can restore the original image after receiving without losing of any hidden information by recipient in the network.
