An efficient web page watermarking scheme

Nowadays, the security of Web pages becomes very important. Zhao and Lu had proposed a PCA-based watermarking scheme for Web pages; their scheme is an effective tool for tamper-proof of Web pages. However, the PCA algorithm is time-consuming, especially when the size of Web page is too large. Chia-Chi Wu et al. proposed a Web page watermarking scheme base on hash functions, claiming that their scheme is faster than the PCA algorithm. In this paper, we proposed a new Web page watermarking scheme. Experimental results show out that the proposed scheme is much faster than the PCA algorithm and hash functions, and, at the same time, our scheme makes some improvements on Zhao and Lu's scheme.
