Abstract

A biometrics authentication system that performs individual authentication in use of biometrics information facilitates authentication operation and reduces authentication errors. A storage unit stores therein the shape of the body part of the user, of which is captured at the time of registration of biometrics data, and a display unit displays the body part shape from the time of registration when authenticating the user for directly identifying the state of image capture of the body part at the time of registration and for guiding into a state of image capture of the body part similar to the state at the time of registration. The body part can be guided effectively such that the circumstances of body part image capture at the time of authentication and at the time of registration are in agreement, for improved verification efficiency.

Claims18

Dependent claims

A biometrics system, which verifies characteristic data of a body part registered in a storage unit against characteristic data of the body part obtained through image capture to perform individual authentication, comprising:

an image capture device which captures images of a hand of a user to be authenticated in a contact-free manner;
the storage unit which stores characteristic data and outline shape data of the hand obtained in image capture of the image capture device at the registration;
a control device which extracts the characteristic data and outline shape data of the hand from the captured image of the image capture device, reads, at the time of the individual biometric authentication, the outline shape data and the characteristic data of the hand from the storage unit corresponding to inputted identification number of the user and verifies the extracts the characteristic data against the characteristic data which are read from the storage unit to perform the individual authentication;
and
a display device having a display screen, which, at the time of individual authentication, displays both the outline shape of said hand which is read from the storage unit and the outline shape of the hand at the time of verification, obtained from the image capture device in parallel, adjacent and non-overlapping positions on the display screen.

2 more elements

A biometrics method for verifying body part characteristic data registered in a storage unit against body part characteristic data obtained by image capture to perform individual authentication, comprising:

an image capture step of capturing an image, in a contact-free manner, of a hand by an image capture device;
a step of extracting characteristic data and outline shape data of the hand from the captured image of the hand;
a step of storing in the storage unit, at the time of registration, the outline shape data and the characteristic data of the hand obtained in the extracting step;
an input step of inputting an identification number, in order to retrieve, from the storage unit, the outline shape data of a user for whom the individual authentication is to be performed;
a step of reading, at the time of the biometric authentication, the outline shape data of the hand and the characteristic data of the hand from the storage unit corresponding to the inputted identification number of the user;
an authentication step of verifying the extracted characteristic data of the hand against the characteristic data which are read from the storage unit;
and
a display step, at the time of individual authentication, of displaying on a display device having a display screen both the outline shape of the hand which is read from the storage unit and the outline shape of the hand obtained in image capture by the image capture device at the time of verification, in parallel, adjacent and non-overlapping positions on the display screen.
