Paper Abstract
Cellular communications constitute a significant portion of the global telecommunications market. Therefore, the
need for secured communication over a mobile platform has increased exponentially. Steganography is an art of hiding
critical data into an innocuous signal, which provide answers to the above needs. The JPEG is one of commonly used
format for storing and transmitting images on the web. In addition, the pictures captured using mobile cameras are in
mostly in JPEG format.
In this article, we introduce a switching theory based steganographic system for JPEG images which is applicable
for mobile and computer platforms. The proposed algorithm uses the fact that energy distribution among the quantized
AC coefficients varies from block to block and coefficient to coefficient. Existing approaches are effective with a part
of these coefficients but when employed over all the coefficients they show there ineffectiveness. Therefore, we propose
an approach that works each set of AC coefficients with different frame work thus enhancing the performance of the
approach. The proposed system offers a high capacity and embedding efficiency simultaneously withstanding to simple
statistical attacks. In addition, the embedded information could be retrieved without prior knowledge of the cover
image. Based on simulation results, the proposed method demonstrates an improved embedding capacity over existing
algorithms while maintaining a high embedding efficiency and preserving the statistics of the JPEG image after hiding
information.
