<P>PROBLEM TO BE SOLVED: To provide a technique capable of determining the identity between structured documents containing a plurality of document elements, without depending on differences in the order of arrangement of a group of document elements. <P>SOLUTION: A preprocessing part 11 obtains an old hash value from the SOAP header of an inputted SOAP envelope. A normalization subject specifying part 13 specifies a group of document elements to be processed within an SOAP body, and a document structure normalization process part 14 performs a process for rearranging the group of document elements according to predetermined standards. A hash value calculating part 15 calculates a hash value from the group of document elements rearranged. Thereafter, a hash value comparing part 16 compares the old hash value obtained from the SOAP header to the hash value calculated; if they match, a determination is made that a structured document has not been altered. <P>COPYRIGHT: (C)2008,JPO&INPIT |
