摘要

The big revolution from analog to digital makes digital documents extremely used due to many advantages such as cheapness and speed diffusion. Nonetheless, this crossing to digital forms is accompanied with a less controllable distribution. As a consequence, the intellectual copyright is no more protected which may cause some economic losses. In this paper, we intend to present a possible solution to solve copyright ownership problem and to verify the originality of content. In this context, we propose to embed a robust watermark at the Wireless JPEG2000 (JPWL) encoder by using Turbo Trellis-Coded Quantization (turbo-TCQ) technique. In particular, Special attention will be given to joint quantification and watermark embedding, simultaneously, during compression. The extraction of the marque is performed during decompression. The experimental results showed that the proposed joint scheme successfully survives lossy compression attacks generated by the encoder JPWL itself with insignificant alteration of the image quality even at high ratio.
