In the humanistic society today, the design for daily
product or various systems must be designed under the
consideration of human habits and convenience as well as
daily product. The motivation of this paper is the first to
propose a QR-code based one-time password
authentication protocol, which not only eliminates the
usage of the password verification table, but also is a cost
effective solution since most internet users already have
mobile phones. From the user’s vision, our approach
could be more convenient, because the burden of carrying
a separate hardware token or extra charges from the Short
Message Service can be removed. Thus, the contribution
is therefore obviously.
