Image transfer through the network is an important issue in the present time scenario. In this system combination of small cells of secret data to form a target in mosaic sense here Secret-fragment visible mosaic image is proposed. In this method through the image from far appears to be original and made of different pixels but actually the image will be done using fragments. When generation of mosaic image is started original image is sub divided into many tiles images. Before image is getting split, check the host image and the secret image is of same size. Find the best tile image for embedding in the targeted image cells. Placing data of the tile image fitting sequence in the target which is an image is placed into unevenly selected pixel informed mosaic image. Information which is enclosed will be made as a text key file. Image fitting sequences will be present in a key file. Receiver can’t retrieve the embedded data without this key.

Keywords : mosaic image, data hiding, and secret communication.
