The optical structure includes a prism configured to comprise an input surface to which light is irradiated, a contact surface formed horizontally to be in contact with a finger, and an output surface through which the light that has been irradiated to the input surface and reflected from the finger in contact with the contact surface passes; a lighting unit configured to emit a beam to the input surface of the prism; a reflector unit configured to reflect a fingerprint image passing through the output surface of the prism; a lens unit configured to comprise two or more lenses, each being configured to receive the fingerprint image reflected from the reflector unit; and an image sensor on which the fingerprint image passing through the lens unit is formed. | 06-14-2012 |
20120300927 | METHOD OF REGISTERING SMART PHONE WHEN ACCESSING SECURITY AUTHENTICATION DEVICE AND METHOD OF GRANTING ACCESS PERMISSION TO REGISTERED SMART PHONE - A method for registering a Smartphone when accessing security authentication device and a method for access authentication of a registered Smartphone are provided. When a Smartphone based application searches for a device and attempts an access to the found device, the search and access for the device is limited according to a result of authentication using an activation code. | 11-29-2012 |
20130223681 | APPARATUS AND METHOD FOR IDENTIFYING FAKE FACE - An apparatus for identifying a fake face is provided. A first eye image acquirer acquires a first eye image by taking a picture of a subject while radiating a first ray having a first wavelength. A second eye image acquirer acquires a second eye image by taking a picture of the subject while radiating a second ray having a second wavelength that is shorter than the first wavelength. A controller extracts a first area and a second area having brighter lightness than the first area from each of the first and second eye images, calculates a lightness of the first area and a lightness of the second area in the first eye image, and a lightness of the first area and a lightness of the second area in the second eye image, and determines whether the subject uses a fake face based on the calculated lightness. | 08-29-2013 |
20140254891 | METHOD AND APPARATUS FOR REGISTERING FACE IMAGES, AND APPARATUS FOR INDUCING POSE CHANGE, AND APPARATUS FOR RECOGNIZING FACES - A face image registration apparatus comprising: a face video image acquiring unit configured to acquire a front face image and at least one or more moving video images corresponding to predefined face pose changes; a similarity measurement unit configured to measure a similarity of the acquired front face image and each of the acquired at least one or more moving video images; an image selection unit configured to select at least images from the at least one or more moving video images based on the measured similarities; | 09-11-2014 |
20140254892 | FACE RECOGNITION APPARATUS, SYSTEM AND METHOD FOR MANAGING USERS BASED ON USER GROUPING - A face recognition apparatus comprising: a database that stores face information mapped to each corresponding user; a face recognition unit configured to recognize the face information of a user; a user management unit configured to classify the face information into groups of the users of which the face information is not similar one another so that the users having the similar face information does not fall within the same groups to store the classified face information in the database. | 09-11-2014 |
20140286548 | METHOD AND APPARATUS FOR IDENTIFYING FAKE FINGERPRINT - An apparatus for identifying a fake fingerprint, the apparatus comprising: a prism having a fingerprint contact surface with which a fingerprint comes in contacted; an internal light source configured to irradiate light from the inside of the prism; an external light source configured to irradiate light from the outside of the prism; an image sensor configured to acquire diffused light image by the internal light source and transmitted light image by the external light source; and a controller configured to compare the diffused light image and the transmitted light image acquired by the image sensor to determine whether the fingerprint is a fake fingerprint or not. | 09-25-2014 |
20140301599 | METHOD FOR FACE RECOGNITION - A method for a face recognition by a face recognition service server, includes receiving a face image that is photographed from a face registration terminal or a face recognition terminal; detecting a face area of the received face image; and quantifying at least one quality factor for the detected face area in order to determine whether the received face image is suitable as sample image required for face recognition. 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 |
