Abstract |
A new secure image transmission technique is projected, which transforms automatically a given large-volume secret image interested in a so-called secret-fragment-visible mosaic image of the identical size. The mosaic image, which looks analogous to a randomly particular target image and may be used as a disguise of the top secret image, is yielded by sorting out the secret image into fragments and transforming their color characteristics to be individuals of the corresponding blocks of the target image. skilled techniques are planned to conduct the color transformation method so so as to the secret image may be improved nearly lossless. A system of handling the overflows/underflows in the transformed pixels’ color values by recording the color differences in the unreconstructed color space is also planned. The information requisite for recovering the secret image is embedded into the formed mosaic image by a lossless data hiding scheme with a key. |
