Bioscrypt Inc. 5000 Van Nuys Blvd., Suite 300Sherman Oaks, CA U.S.A. 91403 Contact: Christopher Crump Bioscrypt TM We would like to give a special thanks to Bioscrypt™ for donating the Software Development Kit (SDK), OEM support, and other meaningful advice.
Lock and Key System is archaic New technologies, either incorporating memory or biometrics, can help security move beyond the antiquated system of lock and key. Memorization adds security But passwords can be forgotten, shared, or observed Abstract • Most effective security is Biometrics • Biometric technology is a way to achieve fast and user-friendly authentication with a high level of accuracy
What is Biometrics? • Biometrics is an automated method of recognizing a person based on a physiological or behavioral characteristic. • It can be used to uniquely identify one person from another. • Includes fingerprints, speech, face, retina, iris, handwritten signature, hand geometry, and wrist veins • By using an attribute of the body, security is improved because there is no room for human error • Using Biometrics security will increase system effectiveness.
Design Objectives • The Digital Door Assistant will: • Provide a convenient, reliable, and secure alternative to archaic key-entry door systems • Utilize accurate fingerprint identification in order to allow access for authorized users • Perform as an embedded system geared for residential use

Choice of Fingerprint Device • The MV1200 fingerprint scanner: • Unlike many other scanners, is made for embedded devices • Is capable of interfacing with a microcontroller • Contains an accurate identification algorithm onboard • Allows for administration over templates (addition and deletion)
Design with MV1200 MV1200 Fingerprint Scanner Biometric Device Control Doorbell
Choice of Microcontroller • Most simple microcontrollers, like the MC68HC11A8, will have the functionality we need for our design • Documentation from Bioscrypt will finalize microcontroller decision
Design with MV1200 and Microcontroller MC68HC11A8 MV1200 Fingerprint Scanner Biometric Device Control Doorbell
MC68HC11A8 Microcontroller • Available Ports • 5 needed • A-E available • Available Memory • 8k ROM • 256 bytes RAM • 512 bytes EEPROM
MV1200 Fingerprint Scanner • Power: • Data Communication:
Other Devices • Doorbell/Lock • Activates based on output from microcontroller • Buffered data prevents feedback Insert Diagram here…..
Project Flowchart Wait Is Person Enrolled? Delay 5 Seconds Unlock Door Yes No Ring Doorbell Lock Door
Limitations • Power Failure • A backup system is needed • Extensive testing is required • Weather conditions such as rain • Physical modification to packaging
Target Customer • Suburban families • Include as a package in new home constructions • 1,200,000 new homes in 2000 • Direct mailing to electrical contractors • Trade show product promotion
Cost Estimation • Initial 5% of market share • Estimated peak of 25% of market share in year 6
Product Cost/Price • Material, fixed and variable costs • DDA sale price
Conclusion • This project will be completed successfully by April 2002 • Additional functionality will be added if time permits • Possible mechanical design changes
