Institutions of higher education that offer credits through distance learning using web basedtraining (WBT) have increased recently. In these situations, an authentication model usingthe ID-password pair is generally used. However, this authentication model cannot prevent“identity theft” effectively. We propose a new authentication method that solves thisproblem by using cellular phones as an authentication token. The authentication accuracy isexpected to be improved by combining the ID-password pair with the subscriber ID ofcellular phones. We realized a prototype system and prepared a questionnaire in order tovalidate the effectiveness of our proposed method, and as a result, we demonstrated theeffectiveness and realizability of our method.
