Abstract: The present invention provides methods and apparatus that implement techniques for detecting modifications of a form template. The techniques feature receiving a document containing a template definition, and receiving one or more modifications to the document. The techniques further feature identifying one or more data bind nodes within the template definition. The techniques also feature finding any corresponding predetermined hash associated with the document for each of the identified data bind nodes. The techniques additionally feature calculating a hash for each identified data bind node, and comparing the calculated hash for each identified data bind node with the corresponding predetermined hash. The techniques further feature flagging the document if either the calculated hash for each data bind node does not match up with the corresponding predetermined hash or if no corresponding predetermined hash exists for one or more of the data bind nodes.
