10 Claims

1. An electronic device comprising:

a camera;

a memory storing face authentication information and authentication pattern of a user; and

a controller configured to:

recognize a face in an image obtained through the camera,

perform first authentication for determining whether the recognized face is identical with the face authentication information,

track a movement of a gaze of the recognized face when the first authentication is completed, and

perform second authentication for determining whether a movement of the gaze is identical with the authentication pattern,

wherein the authentication pattern includes a pattern to sequentially connect selected corners among corners of the electronic device, and

wherein the second authentication is determined based on whether the movement of the gaze is sequentially performed along the selected corners based on the authentication pattern.
