N2 - When a teacher gathers the students’ assignment ectronically, one big problem is plagiarism of report from documents in a Web site or other learner’s report. This paper proposes a framework using data hiding technology to suppress plagiarism. In this framework, a teacher embeds ID of a student into a template file and sends the template file to the student. The student writes a report using the template file and submits it. The teacher extracts the ID from the report file to validate the file’s originality. The Open Office XML (OOXML) format was chosen as the format of the template file because of its popularity. In the experiment, two methods were examined. The first method inserts small images with the ID into the template file. The second method embeds the ID into the fonts of the heading. According to the results of the experiments, the method using images was fragile against format conversion into PDF, and the method of font switching was more robust while the amount of embedded information was small.
