I am using Ubuntu 12.04 64-bit.

I am looking for a facial recognition program that I could use to log in to my account. I have heard of Pam Face Recognition, but there does not appear to be a package for Ubuntu 12.04, and the PPA has been inactive for a while now.

Are there any alternatives that I could use?

If you get this working test to see if a photo can be used to bypass it. – Tom Brossman Jun 24 '12 at 6:37
Possible duplicate ? – pl1nk Jun 24 '12 at 12:46
I wouldn't count it as a duplicate since (as the OP notes) the solution to that post points to an inactive PPA, plus the solution only works for GDM not LightDM. – jackweirdy Jun 24 '12 at 17:30
You can try if your system is compatible or not. Goto: – Lucio Jun 24 '12 at 23:15
Why would you want that? A printed facebook profile picture of you would be the key to your computer... – Stephan Schielke Jul 1 '12 at 22:42


The proprietary software Cara claims to be able to perform face recognition. This software is non-free but at present they have a free version for personal usage.

The application offers multi-platform support including Linux, and ther is a programming API for C, C++, PHP, Java and C#.

Download and installing requires registration so I was unable to test it's functionality.
