Reliable Authentication Method by Using Cellular Phones in WBT
H. Takamizawa, Kenji Kaijiri · 2006
Institutions of higher education that give the credits by distance learning using WBT have increased recently. In these situations, the authentication model by (ID, password) pair is general. However, this authentication model cannot prevent "Identity theft" effectively. In this paper, we propose a new authentication model to solve this problem by using cellular phones.
