  • Patent number: 10572719
    Abstract: In real biometric systems, false match rates and false non-match rates of 0% do not exist. There is always some probability that a purported match is false, and that a genuine match is not identified. The performance of biometric systems is often expressed in part in terms of their false match rate and false non-match rate, with the equal error rate being when the two are equal. There is a tradeoff between the FMR and FNMR in biometric systems which can be adjusted by changing a matching threshold. This matching threshold can be automatically, dynamically and/or user adjusted so that a biometric system of interest can achieve a desired FMR and FNMR.

  • Patent number: 8661516
    Abstract: A biometric authentication device includes: a matching data generating unit which generates matching data from at least one biometric image representing a plurality of pieces of biometric information of a user; a mutual biometric information feature amount extraction unit which extracts a mutual biometric information feature amount representing the degree of similarity between two pieces of biometric information of the plurality of pieces of biometric information; a selection unit, which, for each of the first predetermined number of the registered users, computes a first selecting score based on the mutual biometric information feature amounts of the user and the registered users and selects the second predetermined number of registered users in order of decreasing the level of similarity based on the first selecting score of each registered users; and a matching unit which matches the matching data of the selected registered users with the matching data of the user.

  • Patent number: 8638994
    Abstract: An electronic device may include a finger sensor, a display, and a controller coupled to the finger sensor and the display. The controller may be configured to collect finger data from multiple portions of a user's finger as the user's finger is moved around on the finger sensor along a finger travel path. The controller may also be configured to generate on the display a finger movement trace corresponding to the finger movement travel path.

  • Publication number: 20140023249
    Abstract: The present invention is an authentication apparatus comprising: a prism of an approximately quadrangle-frustum shape, the prism of the approximately quadrangle-frustum shape is arranged so that a bottom side, out of two parallel surfaces of the prism of approximately quadrangle-frustum shape, is a placing surface side for a finger; a first imaging means is arranged below a top surface parallel to the bottom surface, the first imaging means that images an image of the finger transmitted through the top surface; a light source that radiates light to at least one side surface of a first set of side surfaces, out of two sets of side surfaces of the approximately quadrangle-frustum shape that face each other; and a second imaging means that images the image of the finger transmitted through a second set of side surfaces, out of the two sets of side surfaces.

  • Patent number: 8588484
    Abstract: Exemplary embodiments of method and apparatus for processing the images of fingerprints can be provided. For example, aligned images can be subjected to a tessellation process, whereas each image can be partitioned into a number of regions. Within each region at least one parameter associated with the ridges can be measured and stored. Such exemplary parameter can include, e.g., the prevailing ridge orientation, the average ridge separation and the phase of the ridges. The data can be projected and stored in a multidimensional coordinate system, whereas the representations of any two data can be separated by an amount corresponding to the dissimilarity of these data.

  • Patent number: 8520911
    Abstract: The present invention provides a large format fingerprint capture apparatus, system and method that is low power, compact, and lightweight and has a platen area greater than 3.0 square inches. The present system is typically powered, controlled, and exchanges data over a single data/control/power connection to a host PC, e.g., a desk top computer, PDA, or laptop computer although the system can also be used in a wireless fashion with a power subsystem so no physical connections are required. In a preferred embodiment the large format fingerprint device is directly connected to a completely disconnected portable PC, such as a laptop having only a battery power source. The primary system components of the present invention combine to minimize power, size and weight and, thus, enhance portability and battery life. The system typically includes a light source, a prism, a camera (including the lens), and a case.

  • Patent number: 8515124
    Abstract: An apparatus for determining a fake image includes an image-acquiring block for acquiring an image captured by and input from a camera; and a background-learning block for learning a background of the image to create a learning background. Further, the apparatus for determining the fake image includes a face extracting-block for extracting a face region of a person to be authenticated when an input image for authentication is transmitted from the camera; and an inter-background comparing block for comparing a present background of an input image with the learning background. Furthermore, the apparatus for determining the fake image includes a motion information-comparing block for extracting motion information in the face region and the present background to compare the same with each other; and a fake image-determining block for determining whether the input image is faked using the compared results of the motion information and the backgrounds.

  • Patent number: 8477012
    Abstract: An apparatus acquires information on a user's finger veins for personal authentication and includes: guides which form a space to put the user's finger in and block external light to come into the space sideways; a door assembly which closes when the user's finger is not in place and opens downward by a pushing force of the user's finger when the user's finger is in place, and blocks external light from above the space; a light source section disposed on a surface of the door assembly surface for irradiating the user's finger with light; a filter located at a space bottom and having a reflective surface for reflecting external light coming into the space or light from the light source section; and an imaging unit located under the filter for taking an image of veins of the user's finger exposed to the light emitted from the light source section.

  • Patent number: 8463003
    Abstract: A biometric information acquisition apparatus includes: a light guide that guides a light beam through a plurality of light reflective surfaces; and an image pickup unit that receives the light beam output from the light guide and captures a subject image. The light guide includes an input surface that receives the subject image and is provided at a front surface side; a first light reflective surface that is opposed to the input surface and is provided at a back surface side; and a second light reflective surface that extends in a thickness direction of the light guide. A subject image can be acquired within a desired range by employing the light guide, while suppressing an increase in size of the biometric information acquisition apparatus.
