1. Introduction
The task of setting an R&D agenda for the National Information
Infrastructure can be approached in several ways, which in turn can lead to
different views of the research agenda. The research and development
recommendations in this report were driven by the perceived needs in various
application areas. Thus, at the symposium from which the report was generated,
a plenary session involving presentations by experts in five major application
areas set the stage for the technology-oriented sessions that followed. It
should be emphasized that these five application areas are only representative
of a wide range of applications that will be available in a fully realized NII;
important benefits will be seen in other applications as well.
The five application areas represented in the plenary session were health care,
education, manufacturing, financial services, and government information and
services. Sections 2 though 6 below outline some of the stated needs and
requirements in each of the five areas. Section 7 then summarizes those
requirements for each of the topics that are addressed in the agenda
recommendations (Section C).
2. Health Care
There is much in the press about Health Care Reform. There are many different
ideas about the problems with the health care system and many proposed
solutions to these problems. One area of consensus is that reform is needed.
Issues in the forefront of health care delivery that require solutions include
the escalating cost of delivering high-quality health care, inadequate access
to primary and specialty care by segments of both rural and urban America, and
the duplication of expensive facilities due to the inability of the
infrastructure to enable the sharing of these facilities.
The NII can begin to address a number of the above issues. In particular, the
NII offers opportunities for outreach to geographically underserved regions and
for reducing costs of information-intensive aspects of health care, such as
access to patient records and automation of processes associated with record
keeping, test results, prescriptions, insurance and billing.
2.1 Outreach
Video-mediated face-to-face contact between individuals involved in the
delivery of health care services, i.e., between patients, medical technicians,
physicians' assistants and physicians, has been demonstrated. Physicians have
demonstrated that after an initial familiarization period, they can work well
together without the need to be in one another's presence. Patients have also
found remote consultations with physicians not to be overly intimidating, even
for individuals who have no familiarity with modern communications
technology.
The largest barriers to the use of the present satellite communication-based
systems are the high start-up costs and Earth station support, and the
inability to achieve timeliness. The technology presently allows only a few
facilities to be outfitted with appropriate equipment to support
telemedicine-based consultations, and hence these facilities must be scheduled
in advance.
For NII-based telemedicine to demonstrate its full merit, it must be as easy to
establish telemedicine consultations of all types, when and as needed, as it is
to place voice calls today with "plain old telephone service." This requirement
is complicated by the fact that physicians and other health care providers are
and must be mobile, not only within the hospital, but also in rural areas. The
medical services and applications available via the NII must be available to
all sectors within the medical community--from the rural clinics to the large
medical centers. That is, the communications services must be ubiquitously
available with very fine granularity. There must be the ability to
"dial-a-bandwidth" so that users can request the services and resources they
need, when they need them, and pay only for what they use.
2.2 Lower-Cost Medical Information Access and Management
Health care is extremely information intensive. Each year, Americans undergo 23
million surgical procedures and make approximately 636 million visits to
doctors' offices for ambulatory care.[1] Each of these
visits and procedures generates medical and financial data such as X-rays,
EKGs, patient bills, etc. Today the information is stored in paper files and/or
on computer disks at the sites that delivered the services. There is no easy
access to or sharing of information between physicians or laboratories unless
they are located within the same medical facility.
The concept of "smart cards" and on-line retrieval, which the NII could
provide, allows for the sharing of medical histories, test results, X-rays and
the like, independent of the location of the patients and their medical
records. The integration of handwritten physicians' notes, laboratory results,
X-rays, etc. into an electronic medical record will require addressing a number
of technology problems such as managing incompatible formats and heterogeneous
data repositories, search and retrieval, security, etc. Substantial legal and
social issues must also be addressed, but such issues are beyond the scope of
this report.
As the reliance on electronic data increases, the need for reliable, robust and
available systems becomes imperative. Access to patient information must be
transparent and independent of the patient's physical location. The patient
record should follow the patient around. The systems must be able to access
information from different repositories scattered across the entire country and
even the world. The NII-based applications must be as easy to use as placing a
telephone call using "plain old telephone service." User friendliness and
tolerance for human errors are a must. The engineering details must be hidden
from the health care provider.
The security of the patient data/information must be addressed within several
domains:
- Security of the data repositories; authentication and verification of who
can access data sets.
- Absolute privacy in the transmission of any data involving the patient.
Further technologies specifically needed for the health care industry include:
- Large flat-panel displays that are low cost and high resolution.
- Compression coding that does not produce unacceptable artifacts in image
and video clips.
- Reliability and 100 percent available networking services.
- Digital capture of radiographic film imagery.
- Tools and techniques to provide outcome analysis to quantify the impact of
the treatments provided to patients.
2.3 The Need for Proven Technologies
The health care industry cannot be on the leading edge of the NII technology
drivers. What are "production systems" to some applications may be considered
by the health care industry as prototypes. The trust and confidence of both the
patient and the physician must be built over time with particular concern for
privacy and reliability. The ongoing concern for malpractice suits may slow the
acceptance of NII-based technologies until the technologies are proven.
3. Education (K-12)
While a doctor from the 1890s would be at a loss in the operating room of the
1990s, a teacher from the 1890s would be totally at home in today's classroom.
The use of textbooks (with a six-year life cycle), a talking-heads (didactic)
delivery approach, blackboards and field trips still form the basis for the
classroom experience. Historically, classroom walls isolate both teachers and
students from other teachers and students. Within existing education systems,
the infrastructure that industry/business takes for granted is not in place.
Many schools have only one phone line into the building. Thus, teachers do not
have phone lines to their classrooms. Over the last several years, computers
have become more pervasive in the classroom. However, the computers that are in
place are often not linked, and if they are, it is usually only to share a
printer or file server. A large percentage of schools have cable installed in
the classrooms because cable companies have offered free connections in order
to win franchises in the community. However, cable connections currently
provide only video and one-way communication.
The NII will offer many exciting opportunities for elementary and secondary
education. For example, children move from school to school; having
applications and information follow the student will provide for continuity in
the child's learning process. Furthermore, access to student records that
include examples of work highlighting the child's progress and capabilities
will enable teachers to tailor their education programs. Other substantial
benefits will include transitioning from:
- Print media (e.g. paper textbooks) to electronic media.
- Static learning to learning via the use of real data, interactions with
experts in a given field such as science or art, and "field trips" to Europe,
museums, laboratories, etc.
- Isolation to collaborative teaching and learning.
- Talking heads and listeners to high levels of interaction.
- Distance learning from an educator participating concurrently in a local
and remote classroom to distance acquisition of knowledge from remote databases
through peer support.
The transition from the current infrastructure to NII technology in elementary
and secondary education must take into account (and in some cases use to
advantage) available resources, current educational reform efforts and the fact
that more than 16,000 school districts requiring access to the infrastructure
are in rural areas of the United States. Furthermore, security is a key issue.
This is most obvious in the case of student record confidentiality. Another
concern is that children are very creative and incredibly talented when it
comes to finding ways to explore places they are not supposed to be.
Specific technologies and requirements needed by the education (K-12)
application include:
- Interoperability with old equipment and the current infrastructure (cable,
computers, etc.).
- Authoring tools that allow efficient preparation of lectures or modules on
a given subject.
- Secure information systems.
- Copyright protection.
The NII will facilitate the re-engineering of the whole learning process. As
was observed by Connie Stout, the education panelist, "It's hard to know what
[new applications] people will want until they have the opportunity to
experience the technology in real applications." Experience over time will help
shape the needed applications and services. However, educational systems cannot
invest unless they share their investments. The education system should think
about the whole community; it can become a community resource by addressing
applications in areas such as lifelong learning, adult education and job
training.
4. Manufacturing
Traditionally, information infrastructures have supported corporate functions
by improving the efficiency of activities such as payroll and word processing.
Now the shift is toward improving business performance by increasing the
effectiveness of product development, delivery and support. The value of the
NII to manufacturing is in increasing manufacturing's ability to meet
customers' needs. One of the driving forces is reduced cycle time from concept
to delivery. Manufacturing must address its customers' needs for timely
availability of products. Another change is the evolution to on-line production
(lot sizes of one) to meet a customer order.
To remain competitive in this rapidly changing environment, manufacturing
(large, medium and small) must move to the concept of "virtual
corporations"--linking manufacturing directly with its customers, suppliers,
vendors and subcontractors. The integration of the entire
enterprise--development, engineering and manufacturing processes into the
manufacturing infrastructure--is the challenge.
The infrastructure should allow for design teams that are geographically
dispersed to work together and for expansion of the design team to include
customers independent of location. On-line design changes to address a
production problem, design alternatives, substitution of parts/material, etc.
can be done in "real time" with all of the parties involved.
The current infrastructure is meeting some needs. However, manufacturing
applications severely stretch the capabilities. To fulfill the requirements for
manufacturing, the infrastructure must be capable of supporting:
- Large amounts of data moving at very high speeds.
- Stringent reliability requirements.
- Visual representations.
- Speech recognition.
- Videoconferencing.
For the NII to be widely deployed within manufacturing, companies that
participate in the network must see economic value for their customers.
5. Financial Services
The heart of financial services is people receiving and spending money. When
one talks about financial services, one must include accounts and transactions,
deposits and withdrawals, commerce, loans and credit, billing and payment, and
money and other financial instruments. Today's approaches include credit cards,
cash, stocks and bonds, and prepaid cards. None of these work very well in an
NII context as currently implemented.
The NII will accelerate the velocity of money flow by realizing the concept of
a "virtual bank." The virtual bank will allow delivery of services over public
networks 24 hours a day, seven days a week, from any device, anywhere and with
any bandwidth. This will allow people to do their banking at their home, their
office, their car, wherever they are. It will be accessible--no waiting in
lines or busy signals. It will minimize paper and manual processing.
The NII will also allow customer service representatives and financial
specialists using interactive video lines to provide global assistance and
individual customization and personalization of products and services. Analyses
including realistic simulation and visualization of multiple futures can be
made readily available. In addition, transparent third-party real-time
financial services would also be available. These services will renew emphasis
on long-term relationships and provide the flexibility needed by the
customer.
NII financial services such as those outlined above will require the use of
"digital currency." Digital currency must provide anonymous transactions with
the same ease of use and flexibility as cash has today. The buyer requires
assurances of privacy, yet the seller must be assured that the payment is
valid. Thus, specific technologies and requirements needed by the financial
community to realize this vision include:
- Widespread encryption, authentication and digital signatures.
- Defensible audit trails.
- Tamper-proof, tamper-evident digital objects and copy protection for
documents, certificates, receipts and digital signatures.
- Very high-volume, distributed real-time transaction processing and
authorization.
- Real-time anomaly detection.
- Communication and coordination from software agent to software agent.
- Visual representation and modeling for financial information.
- Very high-speed multi-period simulation.
- Near-real-time programming.
- Digital cash/electronic checking/electronic credit.
6. Government Information and Services
Nearly everyone must interact with the government at one time or another. In
many cases, the interaction is complicated, difficult, slow and may require
dealing with a number of different agencies or departments.
The NII provides dramatic opportunities to improve the efficiency and ease of
use of government services. Electronic government overcomes the barriers of
time and distance to perform the business of government and give people public
information and services when and where they want them. It can swiftly transfer
funds, answer questions, collect and validate data, and keep information
flowing smoothly within and outside government. Integrated electronic benefits
transfer; a national law enforcement/ public safety network; intergovernmental
tax filing, reporting and payments processing; an international trade data
system; a national environmental data index; and governmentwide electronic mail
are only a few of the applications and services that will benefit from an NII.
The infrastructure will also allow the government to consolidate and modernize
its data processing centers and standardize some of government's basic
administrative functions, such as payroll, personnel record-keeping, management
information systems, and financial and general ledger accounting. NII's
implementation will thus provide substantial return on investment through
increases in productivity.
The movement toward an electronic government should focus on providing
effective services to the citizenry. As with industry, government should not
simply automate existing practices. Instead, public officials should view
information technology as the essential infrastructure for government in the
21st century--a modernization to give citizens broader, more-timely access to
information and services through efficient, customer-responsive processes.
The move to an electronic government will require overcoming a number of
barriers--some technology-related, some cultural, some regulatory and some
legislative. The government now provides services on an agency-by-agency basis
with little or no sharing of data/information across agencies. This must
change. Furthermore, an incredible volume of information and information
processing services must be converted to electronic form.
Government information and services must be available 24 hours a day. They must
be user friendly and support a combination of audio, video, text and graphics.
Behind the applications, there must be fast and efficient storage, searching
and indexing techniques for information retrieval. Expert systems or agents can
assist the user and will determine user eligibility for specific government
services.
The technical issues that must be addressed include:
- Storage and retrieval of vast amounts of information.
- A uniform interface to government services (one-stop shopping), rather
than one interface per agency.
- Interoperability among different networks.
- Biometrics--smart cards that identify the card to the customer, to the
terminal and to the application.
Success in implementing electronic government also depends on public
confidence. Electronic government must protect the information it processes and
ensure individual privacy. It also must protect national security interests,
permit legitimate law enforcement activities, enhance global competitiveness
and productivity for American business and industry, and ensure civil
liberties. The government must define uniform privacy protection practices and
generally accepted principles for information security. It also must adopt a
digital signature standard and promulgate encryption standards for sensitive
information.
7. Summary
The integration challenges of the NII are without precedent. We must create an
infrastructure that is ubiquitous and transparent. The base technology needs of
the five strategic application areas that must be addressed to move the NII
from a concept to a reality include:
- System components and communication capabilities: Manufacturing
processes require support for large amounts of data moving at very high speeds.
Financial services will include very high-volume, distributed real-time
transaction processing as well as very high-speed simulations of multiple
futures. In these and other application areas, users need to be able to request
the services and resources they need, when they need them, and pay for only
what they use. A given user may need a different bandwidth for each different
application or for the same application at different times. The ability to "mix
and match" is important to all of the five application areas.
- Support for dialogue and collaboration: Within education, health
care and manufacturing applications, two-way communications is an essential
ingredient. The ability for students to talk and interact with an expert
located across the country or the world provides an experience not available
today and will enhance the learning processes of the students. In the health
care domain, "face-to-face" contact between the patient and physician via the
network can offer the same specialized medical resources to all citizens
independent of location. In manufacturing, interactive capabilities will
support geographically dispersed design teams as well as on-line design changes
to address production problems. Financial specialists will also make use of
interactive capabilities to provide global assistance and individual
customization of products and services.
- Information access and multimedia support: Within all of the five
application areas, the ability to store (distributed), search, query and
retrieve data/information in an easy and timely manner is critical. The ability
to store more than text data (voice, video and text) will provide for a richer
representation of the information about an individual, process, product or
service. The federal government has huge amounts of information, distributed
across organizations, that must be accessible via the network. Patient records
including X-rays, EKGs, lab reports and doctors' orders must be stored and
retrieved independent of the location of the information and the patient.
Furthermore, the large amounts of data used by the applications will require
significant advancement in compression techniques for both data storage and
data transmission. In particular, the health care industry needs compression
coding that does not produce unacceptable artifacts in image and video clips.
- Infrastructure for applications development: An application
development environment is needed by each of the five application areas. These
environments must be independent of platform, have interoperability among
platforms and be easy to use. Education applications will benefit greatly from
the development of applications by third parties.
- Dependability: As dependency on the NII increases, reliability,
robustness and availability become imperative. What is now an inconvenience, in
the future could result in the loss of millions of dollars in the financial and
manufacturing arenas or be life threatening to a patient in need of critical
information.
- Manageability: The introduction and acceptance of applications and
services on the NII will grow over time, resulting in a continuing demand on
the network. As the number of users increases, there will be an increasing
demand on the applications, services and network. All components (applications,
service and networks) must be scalable to support the increase in users and
resources in a timely and reliable manner.
- Ease of use: The importance of user friendly, error-tolerant user
interfaces was highlighted by all of the application areas. From an end-user
perspective, the interface is the NII--the network, etc. The interface must be
easy to use for a student in a classroom, a physician in a clinic or a worker
on the shop floor.
- Interoperability: The ability to provide a seamless network is a
necessity for the five application areas. In all of the application areas,
there is a need to connect with existing infrastructures, equipment and
applications. Companies, schools, hospitals, banks, etc., all have made a
financial investment that must be preserved where possible. Users and
application providers should not have to worry about which infrastructure
configuration or version they connect to; this should be transparent to them,
regardless of whether cable, fiber, wireless, etc. is used.
- Security and privacy: Each application area emphasizes the need for
security and privacy. From the confidentiality of patient records to students'
grades, from company proprietary information to financial information to
individual tax information, all must be secure. One of the key factors for
acceptance of the NII in the marketplace will be the level of trust and
confidence that consumers and providers have in the privacy and security
guaranteed in the NII.
- Portability, mobility and ubiquity: Each of the five application
areas has needs for portable, mobile and/or ubiquitous access to the NII.
Health care providers must be mobile in the hospital as well as in rural areas,
and medical information and services must be available regardless of the
location of the information or the patient. Rural school districts require
access to the infrastructure. Manufacturing design teams need to interact with
customers regardless of where the customer is located. Financial services will
be available to people at their home, their office or their car. All citizens
must be provided with access to government services, and law enforcement
officers in particular will require mobile access to government information.
In addition, the application areas highlighted a number of policy and market
issues. A few policy issues include access that is independent of location
(rural or urban), intellectual property rights and interoperability. Market
issues such as low cost/affordability and the need for a global NII were
discussed. These are important issues that can benefit from technology
solutions such as technologies that reduce costs, technologies that allow for
implementation of the intellectual property policies/laws, and wireless and
satellite technologies that may address some of the global access issues.
Although the policy and market issues are important, they are being addressed
in several NII working groups and are outside the focus of this report.
