Due to the large number of students, lectures in the auditorium are likely to be limited to delivering one-sided lecture and conducting final exam. However, it is apparently desirable for students to have opportunities to check their own progress or understanding level through frequent check-up. Some have tried to build information systems for online-test or taking attendance. However, paper could not be replaced by online system due to the inevitable trouble of students' laptop PC or computer network. For this reason, we developed an educational system where the merit of paper and electronic media were merged. The system automatically recognizes student's ID and check marks written in paper. The scanner reads each student's report annotated by the lecturer and creates PDF, and sends it back to each student via e-mail. For the personal information protection, the created PDF is entirely or partially encrypted through the public-key cryptography.
