A Novel Web Page Watermark Scheme for HTML Security

The tamper-proof of web pages schemes mainly includes two aspects, one is the generation algorithm on pre-embedded watermarking, and the other is the program on the watermarking embedded. In this paper, a novel web page watermark scheme is proposed for detecting and locating tampered web-page. Proposed scheme realize the location of the target HTML page tampered. PCA digital watermarking and ULC (Upper-Lower Coding) embedding are separately executed for each column and each row of the original HTML page source code through comparing the calculation results of web page source code row and column with extracted authentication information, to locate the range of the target HTML page tampered. Experiments show that tampered web-page can be detected and the range of tampered web page can be located well using proposed scheme.
