Combined Watermarking Solution for XML Documents
There is a rapid increase in exchange of data over the internet via XML documents. Due to this immense growth in use of XML format, there are certain issues that need to be addressed. Among them two important are copyrights protection and integrity verification of data, exchanged through XML documents. In previous works, solutions for either one or the other are proposed. In this paper, the authors propose a scheme which addresses these two issues at a time using watermarking technologies. Two watermarks are embedded in host XML document; one robust and the other fragile. The robust watermark provides ownership verification solution and the fragile watermark gives the tamper detection mechanism.
