We propose a content based watermarking technique using the MPEG-7 texture descriptor. In the proposed technique, content description technique of MPEG-7 is adopted to watermarking technique. Using multimedia features described by MPEG-7 standard, we propose a watermarking technique where MPEG-7 texture descriptors are regarded as perceptually significant portions. In this paper, the MPEG-7 texture descriptor is utilized to find perceptually significant portion of data for the watermarking. The positions where the watermark is inserting are chosen according to the texture descriptor in DFT domain. In the detection, the texture descriptor is also utilized so that some frequency regions are weighted in the detection procedure. Experimental results show that the proposed method outperforms the conventional transformed watermarking techniques.
