| 20110013812 | ENTRANCE CONTROL SYSTEM HAVING A CAMERA AND CONTROL METHOD THEREOF - An entrance control system having a camera, and a method thereof of controlling entrance are provided. The entrance control system not only controls entrances through a use of an authentication tool based on biometric recognition, but also photographs a person attempting an entry through the camera, maps the information into authentication history and manages the history data. Accordingly, the entrance control system is capable of rejecting an unauthorized person who has forged biometric information such as a forged fingerprint. In order to ensure a reliability of image record of the person, the system processes a facial recognition algorithm to determine if a frontal face of the person is captured, and controls so that an error message is provided to the person if there is an error, and authentication based on biometric recognition is processed only when the face of the person is captured within an image range. | 01-20-2011 |
| 20100303311 | FINGERPRINT RECOGNITION APPARATUS AND METHOD THEREOF OF ACQUIRING FINGERPRINT DATA - A fingerprint recognition apparatus and a method thereof of acquiring fingerprint data are provided. The fingerprint recognition apparatus acquires a user's fingerprint image through a fingerprint sensor, extracts information regarding a fingerprint size, a fingerprint position, a degree of fingerprint contact and a condition of minutiae points, and displays a corresponding error message and guide information through a display unit to encourage a reinput of fingerprint, if determining that the extracted information is not within a predetermined range. As a result, the user is encouraged to input a best quality fingerprint to allow extraction of good print data for either fingerprint enrollment or authentication. The information provided to the user may practically include detailed error and guide information regarding the fingerprint size, a degree with which a fingerprint is pushed to a certain side, a degree of contact or humidity of a fingerprint. | 12-02-2010 |
| 20100098302 | APPARATUS FOR DISTINGUISHING FORGED FINGERPRINT AND METHOD THEREOF - An apparatus for distinguishing forged fingerprint and a method thereof are disclosed. A different threshold angle for total reflection is applied when forged fingerprint is touched on a fingerprint input surface of a prism, and the forged fingerprint distinguishing apparatus and method use the above fact. Accordingly, using a separate light source, from which a ray of light is emitted with a light axis at a predetermined range of incident angle, acquired fingerprint image is compared and it is determined whether the fingerprint image corresponds to authentic fingerprint or forged one. | 04-22-2010 |
| 20100008552 | APPARATUS FOR DISTINGUISHING LIVING BODY FINGERPRINT AND METHOD THEREOF - An apparatus for distinguishing living body fingerprint from artificial fingerprint and a method thereof are provided. A living body recognition unit determines whether fingerprint in question is living body fingerprint or not, based on the unique color of the living body fingerprint and a change of the fingerprint color which is caused due to a change of contact pressure when the living body fingerprint is contacted with the fingerprint input window. A fingerprint recognition apparatus computes color information from the fingerprint image acquired by the color image sensor, and color change information based on the change of contact pressure, and determines whether the fingerprint in question is the living body fingerprint by determining whether or not the computed color information meets a reference color range and/or if the color change information meets a reference condition. | 01-14-2010 |
