Abstract

This paper introduces a new kind of mosaic image called secret-fragment-visible mosaic image, which is automatically create a target image in a mosaic form by composing small fragments of a given image. Secret image is embedded with the target image secretly in the resulting mosaic image. This information hiding is useful for secure communication. To create a mosaic image we transform a 3-D color secret image into 1-D color space, which is useful for finding similarity target image for secret image. A fast greedy search algorithm is created to find a similar tile image in the secret image to fit into each block in the target image. Lossless least significant bit replacement scheme is used to create a secret key. We cannot recover the secret image without secret key. The proposed method designed for dealing a color image is extended to create grayscale mosaic image, which is useful for hiding text type document image.
