Authentication method, and program and apparatus therefor
First Claim
1. An authentication method using living body information, comprising:
- the image input step of continuously inputting section images of a human body part by relative movement with respect to a read unit;
the character area selection step of selecting a living body section image which includes a character shape from an input section image group;
the image connection step of, when living body section images which include the character shapes which are chronologically continuous are selected, connecting both the living body section images to each other to generate a connected living body image; and
the collation step of collating the connected living body image including the character shapes and living body section images which include character shapes which are not connected to each other with a corresponding portion in reference information of a human body part which is registered in advance to authenticate an identical person.

Abstract
Section images of a human body part are continuously input by relative movement with respect to a read unit in an image input step, a living body section image including a character shape from an input section image group in a character area section step, and, when living body section images which include character shapes which are chronologically continuous are selected, the living body section images are connected to each other to generate a connected living body image in an image connection step. In the collation step, the connected living body image including the character shapes and living body section images which include character shapes which are not connected to each other are collated with a corresponding portion in reference information of a human body part which is registered in advance to authenticate an identical person.
