An Efficient Steganography Using Mosaic Image with Enhanced Security

Anisha S ^[29] | Neethu Maria John

Abstract: This paper presents an image hiding method using secret fragment visible mosaic image. In this method the confidential image is converted into secret fragment mosaic image of same or varied sizes. Mosaic image is created by composing small fragments of the secret image in to target image, resulting an effect of embedding the confidential image secretly in the resulting mosaic image. Color characteristics of the tile images are changed to make it similar as the target image. Further improvement on security is conducted by shuffling the mosaic image again and dividing the tile images in different sizes. Secret image is recovered from the mosaic image without any distortions.
