In these situations, an authentication model using the IDpasswordpair is generally used. However, this authentication model cannot prevent “identitytheft” effectively. We propose a new authentication method that solves this problem by usingcellular phones as an authentication token. The authentication accuracy is expected to beimproved by combining the ID-password pair with the subscriber ID of cellular phones. Werealized a prototype system and prepared a questionnaire in order to validate the effectiveness ofour proposed method, and as a result, we demonstrated the effectiveness and realizability of ourmethod.
