fprint is a basic library which does all the dirty work like talking to all the different fingerprint readers and providing an abstracted interface.

Installation

Kernel

Generally speaking, fingerprint readers on ThinkPad computers are connected to the USB bus. Simply verify that USB support has been enabled in the kernel

USE flags

USE flags for sys-auth/fprintd D-Bus service to access fingerprint readers

doc Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally global
pam Add support for PAM (Pluggable Authentication Modules) - DANGEROUS to arbitrarily flip global
static-libs Build static versions of dynamic libraries as well global

Emerge

root #emerge --ask sys-auth/fprintd

Additional software

sys-auth/pam_fprint
A PAM module that uses sys-auth/libfprint's functionality for authentication.
sys-auth/fprint_demo
Provides a GTK+ user interface to the fprint tools (helpful for debugging/testing).
