An Efficient Fragile Web Pages Watermarking for Integrity Protection of XML Documents

摘要

This paper presents a novel web pages watermarking scheme for XML document named DSQC (Double Single Quotes Code). The watermark generated by PCA or hash function are embedded into XML original source code by making use of the XML attribute values feature which must be quoted either double or single. Experimental results demonstrate that the DSQC is a kind of semi-blind watermarking and sensitive for tamper, although the embedded watermark's amount is less than the ULC method. By comparing the time cost and sensitivity with experiment, the hash function is more effective than PCA.
