When you’re still a child, you might want to become some superheroes, such as Superman, Batman, Spiderman or even Inspector Gadget, isn’t it? For those of you that want to fulfill their childhood’s dream, then this Networked Biometric Authentication can turn your dream into real!
If you refer to the above figure, you might doubt with its function. The truth is, it more than you’re thinking here! For your information, this project produces an intelligent system, where it can capture a user’s fingerprint and authenticates it against a database via Ethernet communication. All of the authentication results are being displayed via two color LEDs!
The Networked Biometric Authentication is starting to have its own market, thanks to the increasing need for securing data field. Although this networked biometric authentication is much smaller than the ordinary types, but it’s more efficient than others, which it can be used to secure doorways throughout a complex.
In this project, you’ll need to use a fingerprint cards capacitance based fingerprint scanner as the capturing device. All the data is going to be captured by an ATMega32 microcontroller and stored safely on external SRAM. After that, the data is sending over the microcontrollers USART serial port into a serial to Ethernet converter and then, to a server computer.
Lastly, the computer will perform the filtering and authentication. It sends the results back through Ethernet to the microcontroller. The result will be displayed on the color LEDs instantly!
