Abstract

While the transmission technology of data is increases rapidly, the technology to protect these from unauthorized users need to be enhanced. There are several technologies have used such as cryptography, but this technology don’t provide efficient solution. Digital watermarking technology can provide efficient solution to the above crucial problem. Digital watermarking is applied in several media such as image, audio, video, text. As we know, in most of the applications of digital watermarking, the watermark is used to protect the copyright of digital product. In the other word, the product(cover) is important. According to this fact, we presented a new watermarking concept called intelligent watermarking. We took vector map of GIS (Geographic Information System), as case study. Briefly, the scheme depends on the feature of the cover. The embedding of the watermark can be done in several steps. First extracting some features from the original digital vector map. Second combining these features with external watermark in order to get the intelligent watermark. Third embedding the intelligent watermark in the vector map to get the watermarked vector map. The extracting of the watermark can be done in several steps. First, extract the intelligent watermark from the watermarked digital vector map. Second decomposing the intelligent watermark into features and external watermark. Third reversing the extracted features to features of watermarked vector map. So, if the watermarked vector map is attacked, this watermarked vector map will be distorted, otherwise will not be distorted. Our proposed scheme can be applied in all the other media.
