The Road Ahead n 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.
Fingerprint devices Fingerprint sensors can be embedded in a variety of devices for user recognition purposes
A fingerprint identification system
Hardware Assembly n n n Authentication Module User Interface (LCD) Brain (FPGA board) Communication (Bluetooth) Secondary Module
Authentication Module §Subsystems §Fingerprint authentication §Vital Sign Verification
Fingerprint Module: FDA 01 M n n n n n Standalone device with built-in CPU CMOS sensor (complementary metal oxide semiconductor) Resolution: 500 dpi Power Supply 5 VDC ± 5% Current Consumption < 75 m. A Standby Power Consumption 40 m. A (TYP) Verification Time < 1 sec Image Capture Error Rate < 0. 1% Dimensions 21(W) x 32 (L) x 62(H) Life Time Typically 40, 000 Hrs
Pulse Oximetry n n n 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
LCD Interface
LCD – User Interface n n n n 4 x 20 Serial LCD with Keypad Interface Communication: RS 232 or I 2 C Speed: RS 232 mode 1200 bps to 19. 2 Kbps Fully buffered - no delays in transmission Supply Voltage: +4. 75 to +5. 25 Vdc Supply Current: 10 m. A typical Backlight Supply Current: 90 m. A typical
Secondary Device n n n Receives signal from primary device and activates the controlled device Uses a switch to enable/disable power to the controlled device Sends signals if necessary to activate the controlled device

Some Commercial Products n Palmprint Identification System (Hong Kong Polytechnic University)
Comparison n 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 n n 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 n n Left: A fingerprint-based door lock manufactured by Bio. Thentica 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 n n 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 n n Left: The Face. Pass system from Viisage is used in POS verification applications like ATMs, therefore, obviating the need for PINs. Right: The Identix Touch. Clock fingerprint system is used in time and attendance applications.
