Abstract:
1. An authentication apparatus comprising: an image device that has a selectable function, the selectable function including at least one of a macro imaging function, an auto focusing function, and a zoom imaging function; an authentication device that authenticates a user based on a self imaging of the user, the self imaging being captured by the user with the image device; an authentication limiting device that automatically disables use of the selectable function when the user captures the self imaging of user authentication; and a distance measuring device that measures a distance between the image device and the user, wherein the authentication limiting device prohibits the image device from capturing the self imaging for user authentication when the distance measured by the distance measuring device is smaller than a predetermined value, wherein the user has a portable terminal and the authentication apparatus is used for user authentication of the portable terminal, wherein the authentication limiting device fixes a focal point of the image device within a predetermined range so that the image device must be positioned approximately within the predetermined range to properly capture the self imaging for user authentication.
