With the development of the Internet, getting information through browsing Web pages has become a popular way. How to protect the integrity of a Web page is an urgent problem. As an effective method, a novel fragile watermarking scheme for tamper-proof of Web pages is proposed in this paper for solving the problem. In our scheme, the watermarks that are related to the content of the original Web page are generated based on the SHA-1 algorithm, and then they are embedded into the embedding locations controlled by two secret keys. In the detection procedure, whether a Web page has been tampered or not can be judged effectively only by comparing the generated watermarks with the extracted watermarks. The experiment shows that the proposed scheme has stronger abilities to locate the locations of modifications and to identify the types of modifications.
