Introduction
This issue focuses on recent
project developments and the status of the FMS. We will look
at FMS development, its intended use as a law enforcement tool,
and our plan to take early delivery of the FMS in late 1997 to
support testing.
Project Developments
Central Segment Hardware
and Software Acquisition
Harris Corporation (Harris) subcontracted
with IBM for hardware and software for the NCIC 2000 Central
Segment. Harris awarded the subcontract to IBM following a competitive
procurement. IBM will provide its System 390 computer that uses
Complementary Metal Oxide Semiconductor (CMOS) technology, associated
peripheral equipment, and the system software required to operate
NCIC 2000 in a parallel processing environment. The FBI purchased
storage devices for the Central Segment from an existing FBI-wide
contract.
The Central Segment equipment
and software meet NCIC 2000 requirements for system availability,
reliability, scalability, and maintainability. IBM delivered
an initial system configuration in December 1996. In January
1998, IBM will deliver the remaining equipment and software needed
to support NCIC 2000 at initial operating capability (IOC) in
July 1999. This phased implementation allows the FBI to adjust
the system configuration based on the results of system testing.
The system is scalable and will be able to handle workloads beyond
current projections.
Criminal Justice Information
Services (CJIS) Advisory Policy Board (APB) Meeting in San Diego,
California
In December, the FBI briefed
the CJIS APB on the status of the NCIC 2000 project. The briefing
included updates on the system's software development, new NCIC
2000 files, project costs and funding, work on the FMS, workstation,
and mobile imaging unit (MIU), and other significant accomplishments.
Status of the FMS Development
Overview
NCIC 2000 fingerprint matching
will provide law enforcement officers with improved capability
to determine if they have encountered a wanted person. This capability
will improve identification of wanted persons and reduce the
time officers will be exposed to potentially dangerous situations.
The FMS is intended to provide an officer with information to
support detaining a person NCIC 2000 identifies as wanted, pending
a full ten print identification or other positive identification.
Fingerprint matching employs
both the FMS and user equipment. The FMS is a subsystem of the
NCIC 2000 Central Segment. The FMS provides a centralized matcher
capability, supporting a file of up to 250,000 unique right index
fingerprints. User equipment is located in the local office and
patrol car, and includes NCIC 2000 workstations, Mobile Imaging
Units (MIU), and communications equipment. This equipment is
used to acquire fingerprints, submit fingerprint searches, and
receive responses. Fingerprint images can be obtained using live
scan devices or from inked prints with document scanners. User
equipment converts the images to minutiae and topological data.
This data is used for storage and matching.
Law enforcement officials can
use the FMS to help verify the identity of a wanted person or
to perform searches against the FMS database. There are two types
of searches -- verification and cold search. A verification confirms
the identification of a subject by matching the subject's fingerprint
data against one specific fingerprint in the database. A cold
search checks the subject's fingerprint data against all prints
in the database. If a verification returns a match, the response
will provide a hit confirmation message. If a match is found
from a cold search, NCIC 2000 will provide a hit response, including
a mugshot if one is available.
An FMS inquiry will return only
a "hit" or "no hit" response. It will not
return a list of possible "candidates" for a match.
Note that the absence of a fingerprint record does not necessarily
mean that a wanted person record does not exist. Some wanted
person records may not have an associated fingerprint record.
Fingerprint queries sent to the
FMS are compared only against the NCIC 2000 fingerprint database.
They will not use or access the ten print fingerprint database
associated with the FBI's Integrated Automated Fingerprint Identification
System (IAFIS).
Federal, State, and local law
enforcement will enter FMS information following the same procedures
in which other information is entered into NCIC 2000. However,
the NCIC 2000 software for image processing is required on users'
computers to enter FMS data using the "enter image"
transaction. This extracts minutiae and topological fingerprint
data for entry into NCIC 2000. This software is included on all
NCIC 2000 workstations and MIUs, and will be provided to all
authorized NCIC 2000 users at no cost.
Previously captured fingerprints
can be used for FMS searches or to add a fingerprint to the FMS
database. The right index finger is used. The data retained for
a fingerprint in the FMS will include a black and white (not
gray scale) image of the fingerprint and a data representation
of the fingerprint's minutiae and topological features. While
users can request a printout of the black and white fingerprint
image for visual comparison, this must be used with caution.
The black and white visual representation is not a high quality
image, such as those associated with ten print fingerprint cards.
Update on FMS Development
and Early Delivery Plan
System development and testing
of the FMS are almost complete. Programming for the interface
between the FMS and the Central Segment's main processor is nearly
complete as well. Now, the FBI is working with Harris Corporation
to take early delivery of the FMS (as well as the workstation
and the MIU) in late 1997.
Taking early delivery of the
FMS will give the FBI operational and maintenance experience
and the ability to conduct testing. Harris will provide the FBI
with the FMS, user segment hardware and software, documentation,
and computer based training (CBT) software.
FMS Specifications
The main hardware supporting
the FMS is a VAX 810ft computer and 20 Printrak fingerprint matchers
in a search match processor array. FMS software is programmed
in C.
The FMS processes cold search
requests with a two-stage matching process. The first stage,
using Printrak matchers, compares the person's fingerprint minutiae
against the database and produces a list of candidates with similar
minutiae. This list of candidates is passed to the secondary
matcher, but is not returned to the user. The secondary matcher,
developed by East Shore Technologies, Inc., examines the topological
features of the candidates and decides if an exact match is present
or not. This "hit or no hit" response is then transmitted
to the main processor, where a response is prepared and sent
to the user.
Harris has provided the FBI with
working models of the desktop and hand held live scan devices.
The FBI has used these scanners to demonstrate how a user could
scan a person's fingerprint and receive a response from the FMS.
The demonstration system is on display in the CJIS Division's
Human Interface Technology Evaluation Center (HITEC), located
at FBI Headquarters. Law enforcement officials interested in
a demonstration of NCIC 2000 and IAFIS capabilities should contact
Alan Bozorth (202-324-1195 or 202-324-8750).
FBI Plans for FMS Testing
Step One:
The first step of FBI testing
of the FMS is to gain insight into how it will perform as part
of the larger NCIC 2000 system. This testing will provide data
on the FMS's performance in laboratory conditions designed to
simulate a real life environment. The FBI will perform the tests,
with Harris serving in a consulting role. The FMS will be loaded
with a test database of actual file prints. This testing will
provide benchmark levels of the system's accuracy, give FBI personnel
experience in operating and maintaining the system, gauge the
completeness and ease of use of system documentation, help the
FBI to estimate operations and maintenance costs, and provide
the platform to perform special studies.
The results of this testing will
help the FBI to become well versed in all aspects of the FMS.
The experience gained from identifying and solving problems that
occur during testing will be invaluable. The FBI will communicate
the results of this testing to the user community. We will use
the test data and lessons learned to plan for further testing
with interested States.
Step Two:
This testing will take place
once the FBI and participating States have developed an operational
environment for the tests. The user organizations will send FMS
transactions to the FBI in operational conditions. These test
transactions will provide valuable user feedback and information
about the FMS's concept of operations, user interface, and use
in the field. Problems found during the testing can be isolated,
analyzed, and corrected. This provides training, planning, and
documentation for those who will use, operate, and maintain the
FMS when NCIC 2000 comes on-line. The FBI will report the results
of these tests to the NCIC 2000 user community and will use the
testing information to prepare the FMS for IOC.
This testing will include selected
States. The FBI is looking for States interested in participating
in the testing. If interested, please contact Roy Weise on 304-625-2730.
