So technologies such as XML Web services have
been helpful in improving business processes from
server to server, but till now, they have not been
connected directly to information workers at their
desktops. This has meant that information workers
have not had a way to interact with XML Web
Services directly to access and use the enterprise
information that they need. Therefore, it is essential
to develop a user-friendly application that enables
information workers at their desktops to use XML
Web Services to access and use enterprise infor-
mation in order to explore the full potential of the
XML Web Services that streamlines the process
of gathering information and makes it easier to
reuse information throughout the organization.
In this paper, we discuss the potentialities and
expansibility of application of the XML Web
Services technology to improve the quality of the
Japanese medical services.
The purpose of this study is to confirm the valid-
ity of the Web Service we developed. Through the
experiment conducted in the B to C environment,
we aim to demonstrate the effectiveness of the
Web Service which incorporates various social
infrastructures being developed by enterprises
in the private sector, and to proclaim that this is
the new business model requiring less time and
cost. For the experiment in our study, we selected
three widely diffused social infrastructures: con-
venience stores, Internet connection, and mobile
phones. Furthermore, we intend to prove that the
services utilizing the Web Service contributes to
the building of the safe and convenient social
system.
Another purpose of this study is to prove the
effectiveness of the new roaming technology
which shares authentication results among existing
systems, as well as between different certificate
authorities (CAs). In our experiment, the server
of a convenience store and a mobile phone work
together through a one-stop authentication process
via the Internet connection. Our authentication
roaming technology enables users to enjoy differ-

Our goal is to explore patient's oriented medical
system, that is to say, to develop a user-friendly
application that enables information workers at
their desktops to use XML Web Services to access
and use enterprise information in order to explore
the full potential of the XML Web Services that
streamlines the process of gathering information
and makes it easier to reuse information through-
out the organization. For proof of the concept,
we introduce and review some useful health care
systems which utilize the medical information
services and develop solutions to meet the needs of
patients and medical institutions in this study. Most
healthcare organizations have almost hundreds
of applications running in the enterprise. There
is much information in silos across organization
because these applications often do not “talk
to” each other. Then clinicians find it extremely
frustrating when they search information they
required. In addition, every application has an
extremely different user interface and work-flow.
This may be especially troublesome for clinicians
who travel from one hospital to another. Every
hospital may have a different clinical informa-
tion system that the clinician is expected to use.
Therefore, it is very tiresome and too difficult for
clinicians to learn how to use all these different
systems with their unique user-interfaces and work
flow interpretations.
Today, many key decision makers are often
unable to make informed decisions because the
information they need is trapped within documents
or databases in another part of the organization.
