Security Management Services Based on Authentication Roaming between Different Certificate Authorities - Enterprise Information Systems Design, Implementation and Management: Organizational Applications - page 82

AcknoWLedgMent nology and different CAs is truly innovative and

meets the urgent need in the Ubiquitous Society.
In the future, with this technology, we expect the
service to expand so as to enable printing of more
official documents such as drivers' licenses. The
high speed Internet connections as well as Internet
services have become less expensive, and they are
widely accessible for the greater part of organiza-
tions. The mobile phones, at the same time, have
been equipped with multi-functions and become
so advanced that they can identify the individu-
als with biometric authentication technologies.
Convenience stores are so essential to people's
everyday lives with their easy accessibility at any
time of the day and in any part of the cities. In our
study, we utilized the multi-copying machine at the
Seven-Eleven in a way that it prevents prohibited
duplication of the document while it prints out the
document and retains its authenticity.
Furthermore, what is highly remarkable is
that we provided a secure and protected service
by incorporating existing technologies and social
infrastructures. User can utilize a various services
by registering his or her personal information to the
Website with one-stop authentication. Moreover,
by utilizing this model, corporations that digitalize
their documents for storing and operation purposes
can use the convenience stores as document is-
suance terminals for those corporations. As the
service identifies the authenticity of individuals,
it can also be incorporated with the Time-Stamp
technology to exchange the documents requiring
authenticity.
Our study proved the effectiveness of the
Authentication Roaming Technology to combine
different social infrastructures to create a new
service. Though there are still issues to cope
with outside of the realm of technology including
accountability of each participants and the level
of the service, we expect this service to be soon
available in the real world.
