Two Efficient Fragile Web Page Watermarking Schemes
Peng Sun, Hongtao Lu · 2009
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. In this paper, we proposed two novel fragile Web page watermarking schemes, in which simple principal component analysis and random projections are used to generate watermarks of the Web page. Experimental results show out that the proposed scheme is much faster than the PCA algorithm, and, at the same time, our schemes make some improvements on Zhao and Lupsilas scheme.
