摘要： A method for controlling unlocking includes the following operations. A finger of a user is scanned by a fingerprint recognition module of a mobile terminal to acquire a reference feature-point set of the finger when a touch operation on the fingerprint recognition module is detected. Match the reference feature-point set with M pre-stored template feature-point subsets. Unlock the mobile terminal when detecting that a current template feature-point set matches with the reference feature-point set.

摘要： Systems and methods for image alignment are disclosed. A method includes: determining a first set of patches for a first image and a second set of patches for a second image, wherein each patch in the first and second sets of patches comprises a portion of the first and second image, respectively; determining a set of possible match pairings of a patch from the first set and a patch from the second set; for each match pairing in the set of possible match pairings, computing a transformation operation to align the patch from the first set of patches and the patch from the second set of patches in the match pairing; grouping the match pairings into clusters based on parameters of the transformation operations of the match pairings; and, performing the transformation operation corresponding to at least one cluster to align the first image to the second image.

摘要： A ridge flow based fingerprint image quality determination can be achieved independent of image resolution, can be processed in real-time and includes segmentation, such as fingertip segmentation, therefore providing image quality assessment for individual fingertips within a four finger flat, dual thumb, or whole hand image. A fingerprint quality module receives from one or more scan devices ridge-flow—containing imagery which can then be assessed for one or more of quality, handedness, historical information analysis and the assignment of bounding boxes.

摘要： A portable terminal includes a hardware processor, a storage, a communication interface that communicates with an external device, and a sensor that detects a subject's biometric information. The external device includes an authentication device that executes an authentication process using the biometric information to authenticate the subject. The external device transmits information based on the authentication process to the terminal authentication to obtain a permission to operate an apparatus. The hardware processor transmits the detected biometric information to the authentication device, receives the authentication information from the authentication device, stores the received authentication information in the storage, sets the storage to a state where the authentication information is readable when a predetermined condition is satisfied, and sets the storage to a state where the authentication information is unreadable when the predetermined condition is not satisfied.

摘要： Technologies are presented herein in support of a system and method for performing fingerprint recognition. Embodiments of the present invention concern a system and method for capturing a user's biometric features and generating an identifier characterizing the user's biometric features using a mobile device such as a smartphone. The biometric identifier is generated using imagery captured of a plurality of fingers of a user for the purposes of authenticating/identifying the user according to the captured biometrics and determining the user's liveness. The present disclosure also describes additional techniques for preventing erroneous authentication caused by spoofing. In some examples, the anti-spoofing techniques may include capturing one or more images of a user's fingers and analyzing the captured images for indications of liveness.

摘要： A processor estimates a shape of a subject on the basis of an image of the subject, and a memory stores the shape of the subject. The processor generates a quadratic surface connecting a plurality of points on the subject on the basis of the shape of the subject, and develops each of the plurality of points to a planar surface contacting the quadratic surface. Thereafter the processor corrects the image of the subject on the basis of a position of each of the plurality of points developed to the planar surface.

摘要： The present invention relates to a method for determining a finger movement event on a fingerprint sensor. The method comprises to acquire signals indicative of the portion of finger detecting structures that may be touched by a finger. Based on the ratio between the signals and a total signal level, the position of the finger on the fingerprint sensing device can be determined at two different time instances. Based on the positions which may be the same, a finger movement event may be determined. The invention also relates to a corresponding fingerprint sensing device.
