BioLogin works on Linux machines using the PAM authentication module. This tool can be actually used on all computers where the Debian version is installed. BioLogin is not compatible with LightDM login manager (Ubuntu and Kubuntu v1.1 and followings), but it is compatible with GDM. Before installation, it is necessary that GDM is set as default display manager. Once installed, BioLogin can be run from the dashboard, by clicking on “amilab-biologin-ConfigureGUI”.
BioLogin takes the control of the webcam and detect the user’s face. Please be sure that other applications using the webcam have been closed before this operation. By pressing on the button “Registra un volto” (“Enrol face”), the user’s faces is acquired and associated to the user’s account. It is possible to acquire more than one image of the user’s face, which we suggest if BioLogin must work for protecting the access on a workstation.
After logout, BioLogin is operating and the next authentication will exploit the user’s face instead of the related password, which will be requested anyway in case of recognition failure. The access to the system will be granted only if the face will be evaluated sufficiently near to the one released during the user’s enrolment.
In order to reset the system’s configuration, the tool must be re-run and the “rest” button must be pushed: all store profiles will be completely removed.
BioLogin offers also some “Advanced” settings. For example, the user can alterate the “threshold” value in order to increase or decrease the degree of similarity among faces required by the system during the authentication step. We suggest the use of the “Verification” mode can be useful for setting the correct threshold value. It is also possible to activate the “block screen” modality. After a certain time slot, the access to the system will be blocked until the user will be re-authenticated again by his/her face recognition.
