Abstract: A new impregnable image transmission technique is proposed here, which transforms automatically a huge-size of secret image into the secret-fragment-visible mosaic image of the same size. The mosaic image is looks similar to an arbitrarily selected target image. It can be obtained by fragmenting the secret image and transforming their color characteristics corresponding to the blocks of the target image. Here the dexterous techniques are designed to conduct the color transformation process then the secret image can be recover without any loss. The converted Pixels’ color values having overflows/ underflows can be handled by recording the color differences in the transformed color spaces is also proposed. The mosaic image is embedded by the information required to recover the secret image using a lossless data hiding scheme along with a key.
Keywords: Color transformation, data hiding, image encryption, mosaic image, secure image transmission.
