A Novel Approach for Data Transmission Technique Through Secret Fragment Visible Mosaic Image

Abstract

A new method is created secret fragment visible mosaic image for secure data communication. This mosaic image is created by composing small fragments of a given secret image and selected cover image. The cover image is arbitrarily selected and uses of this image to hiding of the secret image. Secret image and cover image is split into tiny fragments called tile image and target block respectively. Color variation process is used to hiding a tile image in a similar target block. Color transform algorithm is used for transforming color characteristic of each tile image to corresponding target blocks. The extraction of the secret image may be retrieved nearly lossless. If variable size of the secret image and cover image, then resizing the cover image. Customized metafile (CMF) is created to store the required information for retrieving the secret image. Hash value should be calculated to providing integrity of secret message. The implemented method is possible for big volume and different size of the secret image and cover image. The proposed method is feasible for secure and nearly lossless data embedding technique.
