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.

Example embodiments relate to an apparatus for non-invasively estimating bio-information is provided. An apparatus for estimating bio-information may include a sensor part including a pixel array of pixels, each pixel having a light source and a detector; and a processor configured to, based on an object being in contact with the sensor part, drive the sensor part based on a first sensor configuration; obtain contact information of the object based on an amount of light received by each pixel according to the first sensor configuration; determine a second sensor configuration based on the contact information; drive the sensor part based on the second sensor configuration; and estimate the bio-information based on light signals obtained according to the second sensor configuration.

A fingerprint detection touch control display apparatus. The fingerprint detection touch control display apparatus includes a base substrate; a plurality of touch sensors on the base substrate; and a counter substrate facing the base substrate. Each of the plurality of touch sensors includes an invisible tight emitting element; a driving circuit configured to driving light emission of tire divisible light emitting element; an invisible light sensor; and a light shield. The invisible light emitting element is configured to emit light toward the counter substrate, at least a portion of the light being reflected by a touch object on the counter substrate into the invisible light sensor through a via extending through the light shield. The invisible light sensor is configured to detect tire portion of the light, thereby detecting a fingerprint information.

A fingerprint sensor includes a substrate, a light blocking layer that is on a first surface of the substrate and includes openings in a light blocking mask, and a sensor layer that is on a second surface of the substrate and includes photo sensors. A fingerprint sensing method of the fingerprint sensor includes: storing a calibration image; generating an original image, based on sensing signals from the photo sensors; performing calibration on the original image by utilizing the calibration image; and detecting a fingerprint, based on the calibrated image. The calibration image is generated by synthetizing valid regions extracted from an original calibration image corresponding to the original image.

Provided are a display screen, a display module, and a terminal. The display screen includes a display layer. The display layer has a fingerprint recognition area. The fingerprint recognition area is provided with an array of transparent thin film transistors and a transparent medium among the transparent thin film transistors. The terminal includes the display screen described above, and further includes an optical fingerprint module and a frame. The display screen and the optical fingerprint module are fixed on the frame. The optical fingerprint module is on one side of the display screen away from a user of the display screen for display and located in a position corresponding to the fingerprint recognition area, so as to allow lights transmitted and received to pass through the fingerprint recognition area.

A biometric identification apparatus, an unlocking method of biometric identification, and a terminal device are provided. The biometric identification apparatus includes: a fingerprint receiving module, configured to sense approaching of a finger to generate a triggering instruction and collect a fingerprint pattern of a user based on the triggering instruction; and a pulse receiving module, coupled with the fingerprint receiving module and configured to receive the triggering instruction and collect pulse information of the user based on the triggering instruction.

A fingerprint identification device and a fingerprint identification method are provided. The fingerprint identification device includes a self-emitting display panel, a fingerprint sensor and a processor. The self-emitting display panel displays at least one light pattern in a sensing region. The fingerprint sensor senses a finger object located above the sensing region of the self-emitting display panel to generate a first fingerprint image and a second fingerprint image corresponding to the at least one light pattern. The processor is coupled to the fingerprint sensor. The processor determines whether the first fingerprint image and the second fingerprint image have opposite tones to identify the finger object is a real finger or a fake finger.

A biometric authentication device with infection preventive function to prevent infection of pathogens such as virus, bacteria and the like is described. The biometric authentication device with infection preventive function includes: an image acquisition unit configured to take an image of a finger of a person to be authenticated; an authentication processing unit configured to performs an authentication process by the use of biometric information contained in the taken image; and a contact prevention unit configured to prevent the finger of the person to be authenticated from coming in contact with the biometric authentication device by leading the finger of the person to be authenticated to a predetermined position in relation to the biometric authentication device by the tactile sensation.

Systems and methods described herein relate to fingerprint-on-display recognition. In particular, the systems and methods described herein may recognize a fingerprint when a finger of a user is placed on a display and authenticate the user based on the recognized fingerprint. Further, the embodiments described herein may utilize multiple colors and/or secondary factors to reduce erroneous authentications of the user. The approaches may improve the accuracy of fingerprint authentication by using the multiple colors and/or secondary factors.

A fake finger in which a transparent thin film is attached to a finger surface is discriminated. A fake-finger determination device includes: an imaging unit 10 that captures an authentication object as a fingerprint authentication object; a classifying unit 31 that classifies an image captured by the imaging unit 10 into a plurality of regions including at least a skin region and a background region using colors of pixels included in the image; and a determining unit 32 that determines whether or not a foreign substance is present in the periphery of a finger based on a feature of a region classified as neither the skin region nor the background region out of the regions classified by the classifying unit 31.
