Abstract :
Data hiding is one of the effective solutions for the exchange of confidential messages in un-secure communication channels such as Internet. In this paper, we propose a new and effective steganography method for robust hiding of information in images with JPEG format. The data is hidden in DCT coefficients of JPEG conversion of a bitmap image using a low quantization rate (for instance, 75% quantization rate) and then convert back to bitmap format. The new bitmap image is converted to JPEG format again, but with a higher quantization rate (90%, for instance). This resulted JPEG image, which carries the hidden data, is robust against the known attacks such as compatibility, F5, outguess and POV attacks. The experimental results show that although the available data capacity using the proposed algorithm is reduced and limited compare to the other similar methods, but it has a more effective robustness under the these attacks.
