Fingerprint Reader

Many Laptops come with an integrated fingerprint reader which can be used for authentication instead of a password. The fprint project is the most advanced approach to provide a solution for integrating fingerprint readers in Linux - other solutions such as thinkfinger are mostly outdated and don't provide such a general approach as fprint does.

fprint consists of several components:
 * libfprint : The basic library which does all the dirty work like talking to all the different fingerprint readers, providing an abstracted interface etc.
 * fprintd : A daemon which provides access to fprint functionality through D-Bus to applications, such as login managers (GDM, KDM, ...), screen locking mechanisms etc.
 * pam_fprint : A PAM module for fprint.
