  • Patent number: 10377235
    Abstract: The present invention relates to a vehicle safe starting device which controls the starting of a vehicle according to a driver's state. One embodiment analyzes blood alcohol concentration by projecting infrared rays into the driver's skin and receiving a reflected signal, and thereafter controls so that the vehicle is not stared if the blood alcohol concentration is larger than a reference value. Since a general breathalyzer using a driver's exhalation is not used, but infrared rays and a method of skin contact touch using a finger, etc. are used, it is possible to accurately measure the blood alcohol level without giving a driver inconvenience, and it is possible to preempt vehicle accidents by blocking driving in an inappropriate state.

  • Patent number: 10255477
    Abstract: In one aspect, methods that use a novel representation, referred to as an octant feature vector (OFV), are used for matching distorted fingerprints. For instance, a feature-based matcher for distorted fingerprint matching may use a two-step local and global matching scheme to compare a set of feature vectors that are derived from minutiae of a reference fingerprint and a search fingerprint. The relative geometric relationships between the reference minutia and nearest minutiae may be derived and encoded into a feature vector based on orientation difference. The OFV is invariant to the rigid transformations and is insensitive to nonlinear distortions since the relative geometric relationships are independent from the rigid transformation.

  • Patent number: 9773147
    Abstract: A fingerprint enrollment method and a fingerprint enrollment apparatus are provided. A minutiae feature and a pore feature of a first fingerprint image are extracted to obtain a first template. A minutiae feature and a pore feature of a second fingerprint image are extracted to obtain a second template. A minutiae matching score between the minutiae features of the first template and the minutiae features of the second template is calculated. When the minutiae matching score is between the first threshold and a second threshold, stitching, mosaicking or synthesis of the first template and the second template are performed by utilizing a matching relation between the pore features of the first template and the pore features of the second template and utilizing the matching relation between the minutiae feature of the first template and the minutiae feature of the second template.

  • Patent number: 9734379
    Abstract: Fingerprint enrollment is described. An initial procedure in which the appropriate area of the finger is determined from the size of a user's finger, followed by a guidance procedure where guidance information is provided in a pseudo random manner and further fingerprint data is obtained during the pseudo random guidance. When the appropriate area of the finger has been covered, fingerprint data is used in a calculation of fingerprint enrollment data that can be used in subsequent steps in the enrollment procedure.

  • Patent number: 9710691
    Abstract: In order to authenticate a user of an electronic device, an image of the user's fingerprint is captured. Before feature information is extracted, the fingerprint image is enhanced via localized normalization thereby increasing contrast within the fingerprint image. Thereafter, feature information, such as key point data, is extracted from the image and compared to a predefined template to determine whether the feature information matches the template. If so, the user is authenticated. By enhancing the quality of the fingerprint image through localized normalization and other techniques, the reliability of the matching operation is significantly enhanced. In addition, using key point comparisons for assessing similarity between the feature information and the template helps to address inconsistencies relating to finger rotation, scale, and translation during capture.

  • Patent number: 9690973
    Abstract: In one aspect, methods that use a novel representation, referred to as an octant feature vector (OFV), are used for matching distorted fingerprints. For instance, a feature-based matcher for distorted fingerprint matching may use a two-step local and global matching scheme to compare a set of feature vectors that are derived from minutiae of a reference fingerprint and a search fingerprint. The relative geometric relationships between the reference minutia and nearest minutiae may be derived and encoded into a feature vector based on orientation difference. The OFV is invariant to the rigid transformations and is insensitive to nonlinear distortions since the relative geometric relationships are independent from the rigid transformation.

  • Patent number: 9594940
    Abstract: A method and device for compressing a fingerprint template is provided. The fingerprint template is derived from fingerprint image data captured from a sensor. The compressing process initially surveys the fingerprint template to determine one or more starting points for encoding. Subsequently, the compression process selects a starting point from the one or more starting points and proceeds to encode that starting point. After encoding the starting point, the compression process encodes all contours extending from the selected starting point. The above process is repeated until all starting points and their associated contours have been encoded.
