A Fragile Watermarking Scheme for Tamper-Proof of Web Pages
With the development of the Internet, getting informationthrough browsing web pages has become a popularway. How to protect the integrity of a web page is anurgent problem. As an effective method, a novel fragilewatermarking scheme for tamper-proof of web pages isproposed in this paper for solving the problem. In ourscheme, the watermarks that are related to the content ofthe original web page are generated based on the SHA-1algorithm, and then they are embedded into the embeddinglocations controlled by two secret keys. In the detectionprocedure, whether a web page has been tampered or notcan be judged effectively only by comparing the generatedwatermarks with the extracted watermarks. The experimentshows that the proposed scheme has stronger abilities tolocate the locations of modifications and to identify the typesof modifications.
