Security Management Services Based on Authentication Roaming between Different Certificate Authorities - Enterprise Information Systems Design, Implementation and Management: Organizational Applications - page 75

ent Internet services by having different certificate
authorities share their ID information. n this sec-
tion we introduce the text format specifications.

4) The efficiency of collaboratively developing
educational materials, reducing the process
dynamics before making it available to
classes, and reducing the cost of security
by examining the issues in operating with
modified server applications to make them
more suitable and useable within the iDC.
The operationalization of the dynamic image
archives.
5) The validity of the data structuralization,
retrieval, extraction, supply, and utilization
with XML in the knowledge management
systems being developed in the platform.

eMpiricAL Method And resuLts

We examined the possibility of collaboration
among corporations, universities, and research
institutions by building an information sharing
environment prior to applying the XML Web
Services into the data management system which
utilizes the information stored within the iDC.
Second, we examined the effectiveness of the data
storage system and evaluated whether the external
applications are capable of high-level utilization
such as its proficiency of producing knowledge
out of information, presenting data effectively,
and storing know-how (Ohashi.edi,2003b). The
following criteria were examined by the demon-
stration experiment utilizing the collaborative
work test bed:

Especially, the capability of prompting the
collaborative work while protecting the data
privacy by allowing users to switch the collabora-
tive workplaces according to their object where
access is controlled by each organization so that
only permitted group members have the authority
to share data. One-stop services is the original
goal for promoting the Health Care System. As a
means to realize one-stop services that integrates
variety of services, portal has been reviewed and
implemented from the beginning of the stage by
government and with collaboration between public
and private sectors. Implementing Web Services
into the interface between servers and clients,
and implementing not on the portal (server) but
on clients (users) would bring about a new way to
realize one-stop services (Figure1)(Web Services
Initiative,2005). There are two main advantages
of citizen-centric one-stop services:

1). The possibility of collaboratively creating
digital visual image contents in the distrib-
uted environment. All the materials in the
visual library were stored, managed, and
safely backed-up in an integrated fashion
without making duplications at organizations
within in the distributed environment.
2) The potentialities of connecting different
organizations through the iDC with high-
speed network and of building a system with
which users can exchange large amount of
data on-line and on-time. Its effectiveness
of arousing an academic curiosity for the
further development of high-speed, large
capacity data and information exchange and
sharing.
3) The capability of the iDC and the proxy
servers to operate interactive control func-
tions even when clients and their servers are
located in an IP unreachable area.

1) No need of the portal systems that could be
a major burden to construct
2) No need for portal to posses personal
information.

Building of a portal system is very difficult.
From the point of authentication and organizing
interfaces, it is difficult to develop a portal after
each service has been developed. Additionally, it
is also difficult to build a portal before any service
