Face-controlled liveness verification

A non-transitory computer readable medium having stored thereon program code executable by a processor of a computing device, the program code embodying a method comprising:

• receiving, from a user, an indication that the user wishes to access a secured resource on the computing device;
• attempting to authenticate the user based on first biometric data presented by the user to a biometric-based authentication system of the computing device;
• and
• if the attempting to authenticate the user is successful:
• presenting, in a graphical user interface (GUI), a first visual target in a sequence of visual targets, the first visual target being presented at a random location in the GUI;
• determining whether the user has directed his or her gaze at the first visual target for a predetermined period of time;
• if the user has directed his or her gaze at the first visual target for the predetermined period of time:
• changing a color of the first visual target in the GUI;
• attempting to re-authenticate the user based on second biometric data presented by the user to the biometric-based authentication system of the computing device;
• and
• if the attempting to re-authenticate the user is successful, repeating the presenting and the determining steps for a next visual target in the sequence of visual targets.

A computing device comprising:

• a camera;
• a display;
• a biometric-based authentication subsystem;
• a processor;
• and
• a memory having stored thereon program code which, when executed by the processor, causes the processor to:
• receive, from a user, an indication that the user wishes to access a secured resource on the computing device;
• attempt to authenticate the user based on first biometric data presented by the user to the biometric-based authentication subsystem;
• and
• if the attempting to authenticate the user is successful:
• present, via the display, a first visual target in a sequence of visual targets, the first visual target being presented at a random location in the display;
• determine, using the camera, whether the user has directed his or her gaze at the first visual target for a predetermined period of time;
• if the user has directed his or her gaze at the first visual target for the predetermined period of time:
• change a color of the first visual target in the GUI;
• attempt to re-authenticate the user based on second biometric data presented by the user to the biometric-based authentication subsystem;
• and
• if the attempting to re-authenticate the user is successful, repeat the presenting and the determining steps for a next visual target in the sequence of visual targets.
