Project Summary
The fprint project works to bring turnkey support for consumer fingerprint reader devices and biometric authentication options to Linux. The goal for libfprint is to change that by providing a central system to support all the fingerprint readers as it's possible to place in the development team's hands.
libfprint is the hub of a wheel representing several efforts to realize this functionality. This component does the often dirty, low-level job of negotiating the communication parameters with fingerprint readers over USB and processing any raw data received back into a usable image of a fingerprint. To do all this it depends on the new libusb which performs asynchronous callbacks, allowing fprint to perform non-blocking device tasks.
