A Fragile Watermarking Scheme Based on Hash Function for Web Pages

摘要

With the development of Internet, the integrity protection of web pages has become an important problem. A fragile watermarking scheme based on hash function for web pages is proposed in this paper. Watermarks are generated by using hash function and these watermarks are related to the web page's content. Then, the watermarks are embedded into the tags and embedding locations, which are randomly pointed. In the detection phase, regenerated watermarks and extracted watermarks are got from the watermarked web page. Finally, according to comparing the mentioned above two kind watermarks, we can judge whether the web page has been tampered or not. In addition, we can also identify the types of modification and locate the locations of modification.
