Abstract
Embodiments relate to a user authentication device configured to detect a face region in a target object image including at least part of a face of a target object, recognize masked or unmasked in the face region, extract target object characteristics data from the face region of the target object image, call reference data and authenticate if the target object is a registered device user based on the called reference data and the target object characteristics data. The reference data is generated from an unmasked image of the registered device user.
