Abstract

In this paper, to improve the security, sensitivity and efficiency, we propose two novel fragile watermarking schemes for tamperproof web pages, in which a message authentication method and a sparse coding method are used to generate the watermarks for a web page, respectively. The former ensures high security and good sensitivity of the watermarking scheme. The latter attaches more importance to satisfy all the requirements of security, sensitivity and efficiency well. The generated watermarks are then embedded into the web page through the upper and lower cases of letters in HTML tags. The properties of the schemes are illustrated with several experiments, and the results show that the proposed schemes can be good practical tools for the tamperproof of web pages.
