PROJECT TITLE :

A New Secure Image Transmission Technique via Secret Fragment Visible Mosaic Images by Nearly Reversible Color Transformations - 2014

ABSTRACT:

A brand new secure image transmission technique is proposed, that transforms automatically a given large-volume secret image into a thus-referred to as secret-fragment-visible mosaic image of the identical size. The mosaic image, which looks like an arbitrarily selected target image and might be used as a camouflage of the key image, is yielded by dividing the key image into fragments and reworking their color characteristics to be those of the corresponding blocks of the target image. Skillful techniques are designed to conduct the color transformation method so that the key image could be recovered nearly losslessly. A scheme of handling the overflows/underflows within the converted pixels' color values by recording the color variations in the untransformed color house is additionally proposed. The information required for recovering the key image is embedded into the created mosaic image by a lossless information hiding theme using a key. Smart experimental results show the feasibility of the proposed technique.
