On the Confirmation Method of the User's Record of the GakuNinMoodle

The GakuNinMoodle provides the teaching materials for information ethics called "The princess Rin-Rin" to the universities through the academic access federation in Japan named "GakuNin". In order to confirm user's record on the GakuNinMoodle, the administrator of university needs reidentificate anonymized user id saved on the GakuNinMoodle. We compare several methods to reidentificate anonymized user id. LTI is also included one of the method. We are developing the cyberethics grade confirmation system (CEGC) which is used by the university administrator to confirm user's record. In the present paper, we discuss how the confirmation of the user's record are implemented to CEGC. And based on the result of comparison between the confirmation methods and test result of the method, we describe the improved method for next version of CEGC.
