Individual identification device
First Claim
1. An individual identification device which uses an image of blood vessels of a hand to perform individual identification, comprising:
- an imaging device which can image blood vessels of a hand without coming into contact with the hand, comprising;
a position/direction/shape instructing unit for instructing a user to hold up his hand;
one or more irradiating units for irradiating the hand with near infrared radiation; and
one or more imaging units for producing an image by the near infrared radiation;
a blood-vessel image extraction unit for extracting a blood-vessel image from the produced image by said one or more imaging units;
a blood-vessel image storage unit for storing the registered hand blood-vessel image of each user; and
an identification unit for identifying the user by comparing the extracted blood-vessel image with the registered blood-vessel image.

Abstract
In order to provide an individual identification device for enabling good blood-vessel imaging even in a noncontact way and using an identifying method suitable for noncontact imaging, the device comprises an imaging device for imaging blood vessels of a hand of the user in a noncontact way including a position/direction/shape instructing unit for instructing the user to hold up his hand, one or more irradiating units for irradiating the hand with near infrared radiation, and one or more imaging units for producing an image by near infrared radiation; a blood-vessel image extracting unit for extracting the blood-vessel image from the produced image; a blood-vessel image storage unit for storing the hand blood-vessel image of each user; and an identifying unit for identifying the user by comparing the extracted blood-vessel image with the registered blood-vessel image.

18. An individual identification device, wherein the device which performs individual identification by detecting an image of blood vessels of a hand, comprising:
-
an imaging device which can image blood vessels of a hand without coming into contact with the hand by holding a compact and portable pen type imaging device, and which has one or more irradiating units for irradiating the hand with near infrared radiation, and one or more imaging units for producing an image by near infrared radiation;
a blood-vessel image extraction unit for extracting a blood-vessel image from an image produced by one or more imaging devices;
a blood-vessel image storage unit for storing a registered blood-vessel image of each user; and
an identification unit for comparing the registered blood-vessel image with the extracted blood-vessel image to perform individual identification.

19. A computer readable portable type storage medium which is used by a computer which performs individual identification by detecting an image of blood vessels of a hand stores a program which directs the computer to execute:
-
a step for instructing the user how to hold his hand;
a step for receiving the input of the user'"'"'s hand blood-vessel image by near infrared radiation;
a step for extracting the user'"'"'s hand blood-vessel image;
a step for detecting the position and/or direction of the hand;
a step for correcting the blood-vessel image according to the detected-position and/or direction of the hand;
a step for comparing the registered blood-vessel image with the corrected blood-vessel image to perform individual identification.
