Authentication device, authentication method and non-transitory computer-readable recording medium

摘要

To prevent improper authentication, a authentication device includes a visual-line detecting unit configured to detect a visual line direction of a user, an authentication-permission visual-line direction setting unit configured to set an authentication permission visual-line direction, a biometric deciding unit configured to execute authentication by deciding whether a detected visual line direction is an authentication permission visual-line direction, and a display control unit configured to cause a display unit to display an image showing a type of a visual line direction in setting an authentication permission visual-line direction and configured to cause the display unit not to display the image in executing authentication.
