Abstract

XML document is a very popular way to transfer data between databases because of its simplicity of structure and text based data storage. In some typical implementation scenarios where XML document is used to transfer data as XML database, it is necessary to check the consistency of the data at destination. If users are responsible for storing and transferring the document, there is a possibility of data manipulation. In this paper, we propose to apply data verification techniques including checksum and hash algorithms for data verification of XML document. As an advantage, we show that we not only can check the document's authenticity, but also we can identify the specific modified portions of the document. We discuss many popular checksum techniques and secured hash algorithms applied to XML document and compare their efficiency on data verification in the scenarios of the XML data transfer.
