The Road Ahead

Market estimates put the total hardware sales for the industry at US$6.6
million in 1990 and nearly US$400 million in 2000 and over a billion in
2005.
Whether the next decade will result in a similar 2500% increase will depend
upon user demand for positive identification biometrics.

Standalone device with built-in CPU
CMOS sensor (complementary metal
oxide semiconductor)
Resolution: 500dpi
Power Supply 5VDC ±5%
Current Consumption < 75mA
Standby Power Consumption 40mA
(TYP)
Verification Time < 1sec
Image Capture Error Rate < 0.1%
Dimensions 21(W) x 32 (L) x 62(H)
Life Time Typically 40,000Hrs
Pulse Oximetry



Blood oxygenation is measured by
shining a beam of light from an
LED through a tissue bed
(typically, the finger)
Extremely common for use on
patients under anesthesia during
surgery
Biometric system uses Pulse
Oximetry to verify that the client
being authenticated is alive

Smart Card Technology
Store Private Information
Data Encryption
Some Commercial Products

Palmprint
Identification System
(Hong Kong
Polytechnic University)
Comparison

Unlike hand geometry, which measures a
hand-size and finger-length, Palmprint
focuses on the inner surface of a hand, its
pattern of lines and the shape of its
surface.
Application of these products


Left: a fingerprint verification system manufactured by Digital
Persona Inc. is used for computer and network login.
Right: A fingerprint-based point of sale (POS) terminal
manufactured by Indivos Inc., that verifies the customers before
charging their credit cards to speed up payment in retail shops.
Application of these products


Left: A fingerprint-based door lock manufactured by BioThentica Corp.
used to restrict access to premises is shown.
Right: The Immigration and Naturalization Service Accelerated Service
System (INSPASS), which is installed at major airports in the U.S., is based
on hand geometry verification technology developed by Recognition
Systems, Inc.
Application of these products


Left: shows a border passage system using iris recognition at
London's Heathrow airport.
Right: Ben Gurion airport in Tel Aviv (Israel) uses Express Card
entry kiosks fitted with hand geometry systems for security and
immigration.
Application of these products


Left: The FacePass system from Viisage is used in POS verification
applications like ATMs, therefore, obviating the need for PINs.
Right: The Identix TouchClock fingerprint system is used in time
and attendance applications.
