libfprint is an open source software library designed to make it easy for application developers to add support for consumer fingerprint readers to their software.
Features
- Written in C
Licensed as LGPL-2.1
- Depends on libusb for USB communication and glib
- Primarily developed for linux, but should be fairly portable
Offers a single API to application developers to access the entire range of supported devices
- Supports imaging - downloading live fingerprint scans from the device
- Includes image processing/matching code
- Supports enrollment/verification - enrolling a print from a known user, and then later comparing a live scan to the enrolled print
