Biometrics uses a persons biological characters to identify him such as fingerprint scanning, retinal scanning , DNA fingerprinting etc.Biometrics equipped Automatic Teller Machines (ATMs) to provide a number of social services including identity verification and disbursement of social security, unemployment, welfare and pension benefits to a la rge segment of the population.
Biometric Access Control System
The goal of this project is to design and assemble a biometric access control system that uses fingerprint scanning and recognition to authenticate the user. Upon successful authentication, the user will be allowed to access the safe. On the
other hand, if the access is denied, it will be reported to the center administrative console for audit purposes. The fingerprint scanning device utilizes serial communication. This device will be connected to our microprocessor using the UART ports. The system will consist of an Atmel Atmega32 microprocessor, LCD display, fingerprint sensor, electronic door strike, and MCU to USB PC interfacing. Software will be written for the PC that allows the owner to register and delete fingerprints and monitor door entry. LCDâ„¢s and LEDâ„¢s will be used to display whether or not access was granted or denied.
The biggest challenge that will be faced is figuring out how to interface the Atmega32 with a PC via USB and writing software that allows the owner to manage fingerprint access. If time permits a cell module will be used to alert the owner of a possible break-in attempt.
