Abstract: Current multimedia communication systems seek to transmit images supporting contents by the data stream, which requires specific effort for their bandwidth optimization. In this scenario, security of data and information that is being transmitted is highly relevant. A new concept has been recently used in the field of secure image transmission, known as secret-fragment-visible mosaic image. In this case, a mosaic image is created and used as a camouflage for a secret image. The mosaic image is similar to a target image freely chosen. We propose here a technique based on a statistical simplification approach to reduce the number of required bits for recovering the secret image from the mosaic image. We benchmarked the performance of the method and the quality of the recovered image. Experimental results showed that the number of bits with the proposed method was dramatically reduced (close to 3 to 1), and quality metrics were about Root Mean Squared Error of 32 and Mean Structural Simi larity of 0.7 for the created mosaic image. Our proposal paves the way towards improved procedures that are suitable for multimedia systems like digital terrestrial television and similar applications. (More)
