An Efficient Fragile Watermarking for Web Pages Tamper-Proof

The Internet is the most popular and convenient mode of communication for people. An incredible amount of information and many services are provided through the Internet. However, many famous websites often suffer from tampering. Therefore, website security has become an important issue. Recently, Zhao and Lu proposed a PCA-based watermark scheme for web pages, claiming that their process would make web pages tamper-proof and more efficient. However, the PCA algorithm is time-consuming in processing the features of the web page. Therefore, we design a fast fragile watermark for web pages based on hash functions, because hash functions can generate rapidly a digest for the web page. According to our experimental results, our scheme is up to 100 times faster than the PCA algorithm, and, at the same time, our scheme improves case insensitivity and the malfunctions of HTML tags that are drawbacks of Zhao and Lu’s scheme.
