An individual identification apparatus comprising:
- vein pattern identification means for reading finger vein patterns to perform identity verification based on the finger vein patterns;
- and
- facial identification means for imaging a face with a camera to perform identity verification based on facial information,
- the individual identification apparatus determining that a person is a principal when the person is identified by both the vein pattern identification means and the facial identification means,
- the individual identification apparatus being configured such that a reading unit for reading the finger vein patterns and the camera for imaging the face are disposed adjacent to each other, and such that when a finger of the person is placed on the reading unit, the camera images the face of the person,
- the vein pattern identification means including:
- the reading unit irradiating the finger with light to read the finger vein patterns, and images light passing through the finger;
- and
- a vein identification unit having a database in which identification data on the finger vein patterns is recorded in advance,
- the vein identification unit being configured to be capable of receiving imaging information from the reading unit, and
- when receiving the imaging information from the reading unit,
- extracting vein patterns from the imaging information,
- retrieving identification data corresponding to the extracted vein patterns, and
- achieving identity verification when there is identification data with an agreement rate between the extracted vein patterns and the identification data on vein patterns, being equal to or more than a threshold value set lower than a threshold normally set in the vein pattern identification means,
- the facial identification means including:
- the camera for imaging the face;
- and
- a facial identification unit having a database in which facial identification data is recorded in advance,
- the facial identification unit being configured to be capable of receiving imaging information from the camera, and
- when receiving the imaging information from the camera,
- extracting facial information from the imaging information,
- retrieving identification data corresponding to the extracted facial information, and
- achieving identity verification when there is identification data with an agreement rate between the extracted facial information and the identification data on the face, being equal to or more than a threshold value set lower than a threshold normally set in the facial identification means,
- wherein the extracted vein patterns and the extracted facial information are additionally accumulated in the database when identity verification is achieved by both of the vein pattern identification means and the facial identification means, and
- wherein a setting value of a threshold at a time of identification is changed based on an agreement rate between the data additionally accumulated in the database and the identification data to perform identity verification using the changed threshold.
