Abstract

There are several image transmission techniques implemented in the recent world. But there are many compromises in them. Steganography and cryptography are the two main areas of secure data and multimedia transmissions. Here, a secure image transmission technique is introduced using the concept of Mosaic Image Steganography. In this technique we have two images, one being the secret image and the other being the target image. On the sender side the secret image is converted into a mosaic image. The mosaic image generated looks exactly like the pre-selected target image. This image is used as a camouflage of the secret image. It is generated by dividing the secret image and target image into fragments where each fragment of a secret image is called tile image and each fragment of a target image is called target block. Then we transform the color characteristics of the tile to those of the corresponding target block. Next, we embed the recovery information which is a bit steam into the created mosaic image using an improved LSB substitution technique with integer transformation. Before performing this step, we encrypt the recovery information with a secret key. The receiver uses the same key for decryption. To enhance security we encrypt the recovery information with an advanced AES algorithm using chaotic maps. The receiver first extracts the recovery information from the mosaic image using this key and then recovers the secret image using the recovery information.
