With an independent processor on the CryptoCape, we can create some interesting applications. Since the ATmega cannot be flashed from the BeagleBone unless the physical jumpers are attached to the board, we can consider this to be a trusted processor. In this project, we'll implement a biometric authentication system with a fingerprint sensor and the CryptoCape. We'll use the ATmega to prevent access to the security ICs on the CryptoCape until you have authenticated yourself to the ATmega with your fingerprint.

A notable example of fingerprint biometrics in consumer devices is Apple's Touch ID technology on the iPhone 5s. The sensor used on the iPhone is much more sophisticated and expensive than the sensor ...
