Abstract:

Here we implement a secure data transmission technique using an advanced version of Steganography known as the Mosaic Image Steganography (MIS). The technique is implemented using two images as inputs, a cover image in which the secret information is hidden and a target image. Both the images are fragmented and a mosaic image is generated from them. The mosaic image looks similar to the pre-selected target image. The target image is chosen arbitrarily without using any image database. The cover image recovery information is embedded into the mosaic image after encrypting it with a key. The key is generated by the sender and the receiver using the Diffie-Hellman key exchange technique. Since the same key is generated by both parties using this technique, it need not be transmitted by the sender to the receiver. Hence the security issues raised during key transmission can be avoided. After embedding the recovery informations into the mosaic image, it is sent to the receiver. At the receiver side, the image recovery informations are extracted first. Using the informations, the cover image is obtained and hence the data. The technique is found to give good results and is feasible.
