| The system uses two-tier, client-server
architecture for ease of use and fault-tolerant reliability. An integrated,
centralized Operator's Console provides remote video monitoring, annunciation,
video/audio recording and remote manual intervention Client
The client in this two-tier system is tied to the door/access point and
provides biometric authentication, access control, and enrollment services.
Each client/access point can be configured independently to use different
combinations of authentication factors (card, face, finger, PIN). Biometric
templates are cached locally so that verification can occur without a
live connection to the Server.
Users can be enrolled and re-enrolled locally at the client/access point,
even if the client is not currently connected to the server. Data is automatically
synchronized with the server upon re-connection. As soon as the enrollment
images have been captured, authentication of other users at the access
point can continue. As each user is authenticated, new images are captured
to update the user's biometric template. Images are automatically filtered
for maximal variance to provide a more uniform sampling upon which to
build and revise the user's template.
The client can run on Windows® 2000, XP, and CE, and supports the
following peripheral input/output:
 |
- Video capture input
- Audio input and output
- Wiegand input (via RS232 port)
- Wiegand output (via RS232 port)
- Fingerprint input (via RS232 port or USB)
- Keypad input (via RS232 port
- Relay output (via RS232 port)
- Standard keyboard input and VGA output ports
|
The client system is highly user friendly and interactive. Initial user
enrollment is completely automated and the system directs the user where
to stand and in which direction to look. The interactive enrollment procedure
is based on preset heuristic scripting. |
