Further, the method includes selecting the received face image as the sample image required for the face recognition when the quality factor satisfies a predetermined quality criterion. | 10-09-2014 |
20140325641 | METHOD AND APPARATUS FOR FACE RECOGNITION - An apparatus for a face recognition, includes an ID assigning unit configured to assign one ID to a user when registering the user so that the ID is mapped to the user; and a sub-ID assigning unit configured to respectively assign sub-IDs to face images of the user which are different from each other so that the sub-IDS are respectively mapped to the face images when the face images are registered. Further, the apparatus includes a mapping table creation unit configured to create a mapping table in which pairs of the ID and the respective sub-IDs are mapped; and an authentication unit configured to search the mapping table to authenticate the user to provide an authentication result, upon receipt of a request of a user authentication. | 10-30-2014 |
20150022648 | OPTICAL FINGERPRINT RECOGNITION APPARATUS - In accordance with an embodiment, the prism is made slimly to correct the distortion of the fingerprint image such as trapezoidal distortion or the like. Therefore, it is possible to manufacture the optical fingerprint recognition apparatus of a compact size. Further, the imaging lens is arranged to have a de-centering amount and/or a tilt angle with respect to the optical axis, which leads to an effect to implement resolution approaching the diffraction limit. | 01-22-2015 |
20150026479 | CREATION AND AUTHENTICATION OF BIOMETRIC INFORMATION - In accordance with the embodiments of the present invention, the biometric information created for biometric authentication is available for a predetermined time after it was acquired. In addition, the authentication processing is performed on the biometric information useful for a predetermined time after the biometric information was acquired when authenticating it. Therefore, the authentication processing can be normally performed on only the biometric information that is acquired immediately when it is necessary for the user to do the financial transaction or individual authentication. | 01-22-2015 |
