An optimized fingerprinting system for tamper proof and copy control of XML documents

Today, with the fast development of Extensible Markup Language (XML) and increasing amount of data that is published in the form of XML, copyright protection of these data is becoming an important requirement for numerous applications. This study is proposing a system that uses fingerprinting to trace illegal copies and detect any modification made to an XML data. However, the flexible construction of XML data poses a number of challenges to fingerprinting, such as reorganization and alteration. To overcome these challenges, the proposed system has to be based on the winnowing theory, which selects fingerprints from hashes of XML elements. This system is effective to make less distortion to the original data and to preserve usability constraints. Experimental results show that the probability of missing fingerprint detection is very low and the chance to locate changes in the XML data is very high.
