Securing data is one of the key areas of interest in todays world. There are many algorithms for data encryption, and data hiding such as LSB Substitution etc., which are frequently used. All the above methods suffer from disadvantages of threats by hackers. A new method which transforms automatically a given large-volume secret image into a secret-fragment-visible mosaic image of the same size has been proposed. The mosaic image, which looks similar to an arbitrarily selected target image and may be used as a camouflage of the secret image, is yielded by dividing the secret image into fragments and transforming their color characteristics to be those of the corresponding blocks of the target image. This paper focusses on near lossless recovery of secret image which is embedded in another mosaic image. The experimental results show the superior performance of the proposed method.
