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.

1. An authentication device configured to execute authentication based on an image, the authentication device comprising:
a processing unit configured to control the authentication device to operate as:
a visual-line detecting unit configured to detect a visual line direction of a subject photographed in the image;an authentication-permission visual-line direction setting unit configured to set a visual line direction for permitting authentication;an authentication executing unit configured to execute authentication by deciding whether a visual line direction detected by the visual-line detecting unit is an authentication permission visual-line direction set by the authentication-permission visual-line direction setting unit; anda 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 by the authentication-permission visual-line direction setting unit and display an image that does not suggest a type of the visual line direction in executing authentication by the authentication executing unit, the display control unit being further configured to cause the display unit not to display the image in executing authentication by the authentication executing unit.
