Facial recognition login for Ubuntu

Now you can log into your Ubuntu with your webcam using this facial recognition login .. :)


Installation

Open a terminal (Applications > Accessories > Terminal) and enter in the following two lines carefully.

sudo add-apt-repository ppa:antonio.chiurazzi/ppa

sudo apt-get update && sudo apt-get install pam-face-authentication

Now run the ‘Face Trainer’ application from the Applications > Other menu.

Now to add the face authentication module to GDM, Ubuntu’s default login-manager:

sudo sed -i '1i auth sufficient pam_face_authentication.so enableX' /etc/pam.d/gdm

sudo sed -i '1i auth sufficient pam_face_authentication.so enableX' /etc/pam.d/gnome-screensaver

Depending on your webcam model/make you may need to install and add libv4l to preload:

• Create the file /etc/ld.so.preload
• Paste in the path to the v411compat.so file commonly found in /usr/lib/libv4l (create it if not found)

Now everything is done,  just restart or logoff your system and have fun.. :)

Uninstall

In case you want to uninstall this service, just follow these steps-

edit /etc/pam.d/gdm and remove this line: 

auth sufficient pam_face_authentication.so enableX

then, edit /etc/pam.d/gnome-screensaver and remove this line: 

auth sufficient pam_face_authentication.so enableX

then, run this code in your terminal and wait for the system to get restart:

sudo /etc/init.d/gdm restart 

The service has already been discontinued, but you need to remove the useless support files from your system, so when the system resumes,  just remove the FACE TRAINER application

then, run the following code in your terminal:

sudo rm /etc/ld.so.preload

then, edit v411compat.so file commonly found in /usr/lib/libv4l, and remove the path:

/etc/ld.so.preload

Now you are done, The face recognition has been completely removed from your system..
