Apparatus, method, and program for personal identification
First Claim
1. An apparatus for personal identification comprising:
- a storage unit for storing an image of a wrist blood vessel pattern of a certain person as a registered image;
an image pickup section for picking up an image of a wrist blood vessel pattern of a human body;
an identification section for computing a degree of similarity according to a data difference between the image of the wrist blood vessel pattern picked up by the image pickup section and the registered image to carry out identification according to the relationship between the degree of similarity and a predetermined threshold;
a positioning section enabling positioning of a wrist thereon; and
a recessed section formed in a recessed shape on a top surface of the positioning section, wherein the image pickup section is located on a bottom surface of the recessed section, such that the wrist blood vessel pattern is not distorted at the location of the image pickup station when the wrist is positioned in contact with the positioning section.

Abstract
An apparatus and a method for personal identification include an image pickup section for picking up an image of a blood vessel pattern of a wrist, a storage unit for storing in advance an image of a blood vessel pattern of a certain person as a registered image, and a control section (CPU) for the computation of degrees of similarity according to data differences between the image of the blood vessel pattern picked up by the image pickup section and the registered image to determine identification according to the relationship between the computed degrees of similarity and a threshold, thereby eliminating the need to carry out processing by a characteristic extraction section or the like.

4. A method for personal identification comprising the steps of:
-
storing, in advance, as a registered image, an image formed by extracting spatial frequency components within a predetermined range from an image of a wrist blood vessel pattern of a certain person; picking up an image of a wrist blood vessel pattern of a person to be identified; and forming an identification image by extracting spatial frequency components within the predetermined range from the picked up image of the wrist blood vessel pattern to determine whether the person to be identified and the certain person are the same, according to a degree of similarity between the identification image and the registered image; wherein picking up the image of the wrist blood vessel pattern is performed by prompting the positioning of a wrist in contact with a positioning section having a recessed section formed in a recessed shape on a top surface of the positioning section, wherein the image pickup section is located on a bottom surface of the recessed section, such that the wrist blood vessel pattern is not distorted at the location of the image pickup station when the wrist is in contact with the positioning section. - View Dependent Claims (5, 6, 11)

7. A computer program product, for personal identification, the computer program product stored on a computer readable medium and adapted to perform operations comprising:
-
storing, in advance, as a registered image, an image formed by extracting spatial frequency components within a predetermined range from an image of a wrist blood vessel pattern of a certain person; picking up an image of a wrist blood vessel pattern of a person to be identified; and forming an identification image by extracting spatial frequency components within the predetermined range from the picked up image of the wrist blood vessel pattern to determine whether the person to be identified and the certain person are the same, according to a degree of similarity between the identification image and the registered image; wherein picking up the image of the wrist blood vessel pattern is performed by prompting the positioning of a wrist in contact with a positioning section having a recessed section formed in a recessed shape on a top surface of the positioning section, wherein the image pickup section is located on a bottom surface of the recessed section, such that the wrist blood vessel pattern is not distorted at the location of the image pickup station when the wrist is in contact with the positioning section. - View Dependent Claims (8, 9, 12)
