What are the problems with existing padlocks? Forgotten / Lost / Stolen password key combination / code
What is a biometric? A biometric is a unique, measurable characteristic or trait of a human being for automatically recognizing or verifying identity.
Why the fingerprint biometric ? Fingerprints are very unique. “… statistically it is likely that 50 people on Earth share a fingerprint.” http://biometricaccess.com Easily collected Many commercial sensors available non-intrusive (Accepted by the public)
How can implementing a biometric improve these problems? No password to remember No key to carry with you Fingerprint is not easily stolen Nearly impossible to forget a finger at home
Biometric PadlockDimensions and Weight Size: 6” x 2” x 5” L x W x H Weight: Less than 5 lbs
Veridicom Fingerprint Sensor Small size Low power consumption Finger sensing software
PC104 SBC Identical Architecture to the PC 104 Pins
Why the PC104? • Compatible with the standard PC • The PC104 is the standard for embedded applications • Meets requirements for reading from the sensor • Meets requirements for running our software • Small dimensions
PC104 Advantages Has nearly every function of a PC Develop software on PC Easily run DOS executables Can use any Processor Portable because of size
PC104 Processor Intel 80386 CPU Cheapest Available Processor Will run matching software efficiently
PC104 Memory 8MB memory chip sufficient memory for OS, template, and software
PC104 Interfacing Parallel ports used for: input from sensor buttons LCD display
PC104 Specifications +5V (low power consumption) 0.6lbs (lightweight) (3.5” X 3.7” X 0.6”) (compact)
Battery Selection The following is a list batteries that are available to our design application: NiCd (Nickel Cadmium) NiMH (Nickel Metal Hydride) Li-ion (Lithium Ion) SLA (Sealed Lead Acid)
Battery Selection Battery research has led to two selections currently being considered by the design team. 1) Nickel Cadmium (NiCd) 2) Lithium Ion (Li-ion)
BatterySelection Nickel Cadmium Pros Fast/Simple charge High Number of charge/discharge cycles Economically Priced Cons Subject to memory Has a high discharge rate
Battery Selection Lithium Ion Pros Better manufacturing techniques will reduce price by 50% after the year 2000. Very low self discharge High Number of charge/discharge cycles Cons Expensive
