Claim 5:
6. The three-dimensional authentication device according to claim 1, further comprising an authentication processing unit that determines and outputs a three-dimensional authentication result of the authentication target based on the image authentication result and the distance authentication result,
wherein the registration information storing unit stores a plurality of the registration image data and a plurality of the registration distance data;
the registration image data is stored in the registration information storing unit in correspondence to identification information on the authentication target of the registration image data;
the registration distance data is stored in the registration information storing unit in correspondence to identification information on the authentication target of the registration distance data;
the image authentication unit verifies the authentication image data against the plurality of the registration image data respectively, and when there is the registration image data having a predetermined image authentication threshold or more, in the registration image data, determines the identification information stored in correspondence to registration image data at a highest degree of match as an image authentication result;
the distance authentication unit verifies the authentication distance data against the plurality of the registration distance data respectively, and when there is the registration distance data having a predetermined distance authentication threshold or more, in the registration distance data, determines the identification information stored in correspondence to registration distance data at a highest degree of match as a distance authentication result; and
when the image authentication result matches the distance authentication result, the authentication processing unit determines that verification is successful.
