Abstract
The long term signature (LTS) is composed of an electronic signature and timestamp and it may be an effective technology for protecting intellectual property. This study describes a method of applying LTSs to files generated by office applications. The targeted files are in Open Office XML (OOXML) and are opened by MS Office 2007. XML LTS is described in XAdES format. Two types of LTS, that is, standard LTS and expanded LTS, can be used to apply XAdES to OOXML. The standard format involves a LTS description in a XML signature file that is defined by OOXML. The expanded format separates the LTS description from the XML signature file. Both formats satisfy the OOXML and XAdES specifications. As a result of reading two XAdES signature word processing files by using Office 2007, the file with the expanded LTS was recognized as a valid file with an XML signature, whereas the file with the standard LTS was not.
