  1. Biometric Security System Capstone Project CDR Mat Merkow Tung Nguyen Dipesh Shakya

  2. Project Description • Interface for secure wireless communication • Capable of connecting many sensors and devices • secure data transmission and remote device operation • Our implementation is a wireless security device giving access to remote devices • personally identifiable information will ever leave clients possession

  3. Goals in Order of Importance • Finish boards and have secure communication between them • Serial communication • LCD • Keypad • Bluetooth communication • Operation Controlled Device • Fingerprint/Pulse Oximeter Authentication • Software

  4. System Overview

  5. Internal Communications

  6. Bus Drivers Micro controller Latch

  7. FLASH EPROM RAM (8Kx8 bits)

  8. CPLD • Chip Select • Interrupt handler • Some behavior logic

  9. Finger Chip ModuleAT77SM0101BCB02VKE • Standalone device with build-in CPU

  10. Hardware Schematic

  11. Pulse Oximeter • 34 mm by 24mm • Low power 29mW • RS-232 communication • Demonstration Software • All Cables • One free sensor • Cost: $300.00 + shipping

  12. Pulse Oximeter Data Format

  13. BlueTooth Communication User Interface Communication Module BlueTooth Tx/Rx TDK BISM • TDK Bluetooth Intelligence Serial Module • Stand alone module with integral antenna. • Frequency: 2.4 - 2.485 GHz. • Range: upto 100 meters. • Physical size: 84 x 69 x 5 mm. • Data transfer rate: upto 200 kbps. • Cost $106 Wireless Medium BlueTooth Tx/Rx Secondary Module Controlled Devices

  14. LCD INTERFACE ACM1604C Features: 16 Characters x 4 Lines. 5 x 7 Dot Matrix Character + Cursor. Built in LCD Controller/driver, equivalent to HD44780. LED Backlight version. Size : 87 x 60 x 13.5 mm. Display Area: 61.8 x 25.2 mm. Power Supply Voltage: 2.7V – 6.5 V. Power Supply Current: 0.5 – 1 mA LED Supply Voltage: 4.6 – 5 V LED Supply Current: 200 – 400 mA Cost: $30.04 + shipping.

  15. Progress • Wire-Wrap board has been completed and tested through EPROM, NOP loop runs our system. • Schematics have been created for HC11, Memory, and CPLD. • Vender for Pulse Oximeter has been researched and selected.

  16. Time Chart

  17. Contingency Plans • Unable to get Fingerprint module working • Use keypad for authentication • Unable to get Bluetooth working • Use wires to connect the devices • Unable to get PCB boards working • Build a second wire-wrap board
