Fingerprint Readers

Summary

The goal of the project is making fingerprint readers as easy as possible to use for authentication (primary or secondary).

Owner

  • Name: JosePlans, BastienNocera

Current status

  • Targeted release: Fedora 10
  • Last updated: 2008-06-01
  • Percentage of completion: 25% (planning)

The fprint package was added to Fedora CVS (and built ). It is now available for Fedora 7, Fedora 8 and later.

The pam_fprint package has been added to Fedora CVS (and built ). It is now available for Fedora 7, Fedora 8 and later.

The fprint_demo has been added to Fedora CVS (and built ). It is now available for Fedora 7, Fedora 8 and later.

More details on the current status (as of writing, 2008-06-01) are available in Daniel Drake's project report .

Most of the applications of fprint would need fprintd, which requires: libusb-1.0 (async design, not compatible with 0.1), and the async branch of libfprint.

Detailed Description

Currently, using Fingerprint readers is a bit of a pain, and installing/using fprint and its pam module take more time than should ever be necessary.

Benefit to Fedora

Better Out-of-the-box experience for systems with fingerprint readers.

Scope

Better integration would mean

  • Having a D-Bus service that's a HAL singleton for handling reading/using the fingerprint reader. Potential API (BastienNocera, API needs loads of work). (snipped)
  • Most of the API is already implemented in fprintd, the D-Bus daemon. It uses service activation instead of being a HAL singleton. Identification parts of the API are missing.
  • The PAM module would use the Verify method provided over D-Bus to authenticate users, and will be added to the default configuration.
  • gnome-about-me would use the Acquire method to write a new fingerprint data file for the specified user.
  • gnome-screensaver would be able to use finger scans to unlock the desktop
  • Any other dialog presented to the user for authentication would be able to use finger scans
  • The create-user dialog in firstboot or its replacement could offer to enroll the new user

Test Plan

  • Person installs a laptop/desktop system with a fingerprint-reader that's supported by fprint
  • Person sets their fingerprint in gnome-about-me or in the user creation firstboot module
  • Person can log in using their fingerprint

Documentation

Dependencies

  • Changed backend library from thinkfinger to fprint , after discussion with the maintainers of those two modules.
  • libusb 1.0 (async design, not libusb 0.1 already available in the distribution)
  • async support in libfprint (see above)

Contingency Plan

Not installing the packages by default.
