Information security is turning out to be progressively essential in the modern networked age. Secure image transmission has the potential of being adopted for mass communication of sensitive data under the scrutiny of an adverse censoring authority. Several steganography techniques for transmitting information without raising suspicion are found in Literature. However, secret-fragment-visible mosaic images permit the user to securely transmit an image under the cover of another image of same size. This effectively accomplishes an embedding capacity of eight bit per pixel. In recent years, data hiding has been proposed as a likely technique for the motive of information privacy, authentication, fingerprint, protection, data mining, and copyright protection and etc. In this paper, a technique for secure image transmission is done by transforming a secret image into mosaic fragment visible images with the size almost the same and similar to the target image. Since the target image is selected randomly, Mosaic image should look similar to the target image, which will be used to hide the secret image. In this proposed paper, secret fragment visible mosaic image method is used, which is automatically created by composing small fragments of a given image and the target image, in order to achieve effect of embedding the given image visibly but secretly in the resulting mosaic image. For the resulting mosaic image, reversible color transmission is performed in order to reduce the distortion and also to recover the secret image exactly from the cover/input image. Good experimental results illustrate the feasibility and effectiveness of the proposed method.
