will be developed because it means to design a
gigantic system from scratch.
In terms of the personal information necessary
for one-stop services, though temporally, portal
needs to acquire and possess all the information.
On the other hand, the citizen-centric model would
enable users to submit bare minimum of personal
information from their PCs to receive individual
service. On the other hand, the weak point is that
it is required for users to equip themselves with a
program that realizes one-stop services; hence it
is not suited for the systems that are less used by
general public. In general, portal model is suited for
simple services that are less often used by general
public. It is appropriate for the G2C services while
citizen-centric model is suited for complicated
services that are often used by specific users.
Therefore, it is appropriate for the G2B services
and in G services inside government offices.
possible to collaboratively edit and process image
data between remote locations using high-speed
network and From the experiment, the follow-
ing benefits of applying the XML Web Services
were proved:
Flexible cooperation and collaboration
through sharing the ICT resources
Flexibility in data exchange
Automatic execution of modules
Applicability to existing internet-based
technologies (vendor independent)
Effective utilization of existing programs
Low cost for implementation(Ohashi

In order to protect the security of the B to

results for the demonstration
experiment
The demonstration experiment proved that real-
time discussion with sharing data and resources
among the geographically-dispersed teams was
possible. Furthermore, we confirmed that it is
Authentication Roaming: When integrat-
ing different systems with the Web Service,
some systems require authentication of users.
Therefore, we implemented the authentica-
