  • Patent number: 11436774
    Abstract: A system, method, and computer program product for efficiently mapping a pattern, such as a fingerprint, from a set of multiple impressions of portions of that pattern. The system may evaluate images of patterns taken from a series of multiple impressions and map the pattern from the image portions while providing the operator with realtime feedback of a status of the set of images. As each new image portion is evaluated, a display graphic or other indicator provides feedback when a new image portion is added to the reconstructed image, or when a new image portion is not added (such as it representing a duplicate). Other status indications may be provided, and when the indication is visual, a degraded resolution of the pattern map may be provided on the display graphic to improve security.

    Abstract: A list of possible mated minutiae in a reference fingerprint and a search fingerprint is identified. The list of possible mated minutiae is divided into different groups of mated minutiae using pose grouping based on rigid transformation parameters. For each group, the possible mated minutiae are filtered to get a set of consistent mated minutiae pairs having similar rigid transformation. The topological consistency between groups is determined. If any two groups are topologically consistent to each other, they are merged to form a (virtual) larger group. A non-linear transformation parameters are estimated from the mated minutiae in the merged group. The overall similarity of mated and non-mated minutiae in the overlapping area is determined after non-linear alignment of the two fingerprints, and the maximum similarity is output as the final similarity score between two fingerprints.

  • Patent number: 10826897
    Abstract: A method and an apparatus for authenticating user using biometric information. The apparatus authenticates the user by performing: generating a first feature vector from first biometric information of the user obtained by the biometric sensor and multiplying the first feature vector by a plurality of pseudo-random number (PRN) matrices, respectively; generating a query template based on an index of an element having a maximum value among elements of a result vector of the multiplication between the first feature vector and the plurality of PRN matrices; and performing authentication for the user by comparing the query template with a pre-stored reference template of a subscribed user.

  • Patent number: 10803289
    Abstract: A fingerprint reader includes a display screen composed of an array of energy emitting pixels covered by a transparent cover, at least one sensor coupled along an edge of the display screen, a display driver directing the array of energy emitting pixels of the display screen to illuminate in a predetermined sequence, and a microprocessor in communication with the display driver and the at least one sensor. The microprocessor knows the location of the energy emitting pixel being illuminated and the specific time at which the illumination occurs. In use, and when at least one finger is placed on the transparent cover and the display driver is activated, energy from each energy emitting pixel sequentially illuminated is reflected off the fingerprint to the at least one sensor. The energy received at the at least one sensor is at different intensity levels depending upon the ridges and valleys of the at least one fingerprint.

  • Patent number: 10764054
    Abstract: A device, method, and computer readable storage medium generate a biometric public key for an individual based on both the individual's biometric data and a secret, in a manner that verifiably characterizes both while tending to prevent recovery of either by anyone other than the individual. The biometric public key may be later used to authenticate a subject purporting to be the individual, using a computing facility that need not rely on a hardware root of trust. Such biometric public keys may be distributed without compromising the individual's biometric data, and may be used to provide authentication in addition to, or in lieu of, passwords or cryptographic tokens. Various use cases are disclosed, including: enrollment, authentication, establishing and using a secure communications channel, and cryptographically signing a message.

  • Patent number: 10755067
    Abstract: In a method for operating a fingerprint sensor including a plurality of ultrasonic transducers, receiving a plurality of images corresponding to different subsets of the ultrasonic transducers of the fingerprint sensor are received, wherein the plurality of images are non-adjacent. For each image of the plurality of images, it is determined whether the image of the plurality of images is indicative of a fingerprint. Provided a number of images of the plurality of images that are indicative of a fingerprint satisfies a threshold, it is determined whether the images of the plurality of images that are indicative of a fingerprint are collectively indicative of a fingerprint. Provided the plurality of images are collectively indicative of a fingerprint, it is determined that the plurality of images include a fingerprint.
