A secret image hiding scheme is proposed with new security features. This scheme utilizes the mosaic images, which is created from the secret and target images. A mosaic image is similar to that of the target image. The secret image fragments are hidden in the target image by performing appropriate color transformations. The inverse color transformation is performed for the lossless recovery of secret image. The color transformation is controlled by the proper overflow /underflow methods. The relevant information for recovering the secret image is embedded in the mosaic image by a lossless data hiding with the help of a key. Only with the proper key, the secret image is retrieved from the mosaic image

Key Words:  Image hiding, Mosaic images, Color transformation, Data hiding, Image encryption
