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 ... [More] 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. [Less]

fprint aims to plug a gap in the open source desktop, by providing support for consumer fingerprint scanners as standard.
