摘要: Systems and methods for biometrically authenticating a user are disclosed. In one implementation, a biometric authentication system may include a finger scanner for capturing biometric data from a plurality of sections of a finger of a user. The finger may include a distal section, a medial section, and a proximal section. The biometric authentication system may further include one or more processors configured to cause the finger scanner to capture the biometric data from the plurality of sections of the finger of the user. The biometric data may include authentication data and liveness data. The processors may be further configured to access registered authentication data associated with the user, determine whether the captured authentication data matches the authentication biometric data, and determining, using the captured liveness data, whether the finger is a live finger. Additionally, the processors may be configured to authenticate the user after the captured authentication data is determined to match the registered authentication data and after the finger is determined to be a live finger.

摘要: An optical identification method, includes: projecting light on a finger to generate reflected light from the finger; receiving the reflected light by a pixel sensing array to obtain a plurality of finger images; and determining whether the finger images present a liveness characteristic, according to a required exposure time or average brightness of the finger images obtained by the pixel sensing array. When the finger images present the liveness characteristic, the optical identification method further includes: determining identification information according to the finger images; or when the finger images do not present the liveness characteristic, the optical identification method further includes: not determining identification information according to the finger images, and optionally, stopping the pixel sensing array from obtaining a subsequent finger image.

摘要: Disclosed are a system and method for performing spoof detection. The method includes: receiving, by a processor from a biometric sensor, an input image of a biometric; extracting, by the processor, one or more anti-spoof metrics from the input image; receiving, by the processor, an anti-spoof template corresponding to the biometric; for a first anti-spoof metric, computing, by the processor, a differential value between a value of the first anti-spoof metric extracted from the input image and a value of the first anti-spoof metric in the anti-spoof template; and determining, by the processor, whether the input image is a replica of the biometric based on the differential value.

摘要: The present disclosure relates to the field of biometric identification of a user, in particular, to a system and method of identifying a user. The method of identifying a user includes: detecting a portion of a user's finger in contact with a touch-sensitive region of a device; and collecting data relating to a fingerprint of the user from the user's finger for a period of time and obtaining a plurality of frames from the data. The method further includes determining whether the user is an authorized user of the device, based on a ridge pattern, a sweat gland pattern, and dynamics of blood circulation in the user's finger as indicated by the data. The method provides an enhanced security system that can be integrated in a user's mobile device to protect against fake biometric characteristics in access control systems.

摘要: Various examples of systems, methods, and programs embodied in computer-readable mediums are provided for fingerprint liveness detection. Fingerprint liveness may be determined by evaluating pixels of a fingerprint image to identify pores along a ridge segment of the fingerprint image. A circular derivative operator can be used to identify the pores. Liveness of the fingerprint can be determined based upon features of the identified pores.

摘要: An apparatus may include an ultrasonic sensor array, a light source system and a control system. Some implementations may include an ultrasonic transmitter. The control system may be operatively configured to control the light source system to emit light that induces acoustic wave emissions inside a target object. The control system may be operatively configured to select a first acquisition time delay for the reception of acoustic wave emissions primarily from a first depth inside the target object. The control system may be operatively configured to acquire first ultrasonic image data from the acoustic wave emissions received by the ultrasonic sensor array during a first acquisition time window. The first acquisition time window may be initiated at an end time of the first acquisition time delay.

摘要: Provided are an electric field type fingerprint identification apparatus and a state control method and a prosthesis identification method. The electric field type fingerprint identification apparatus includes a signal acquisition module and a signal processing module. In a case that a measuring state signal processing unit is electrically connected to a signal acquisition unit, a to-be-measured state signal processing unit is at least electrically connected to at least one signal acquisition unit peripheral to the signal acquisition unit in a measuring state. Charging and discharging processes of sensing capacitors electrically connected to the measuring state signal processing unit and the to-be-measured state signal processing unit are coordinated to restrain charging and discharging quantities of a parasitic capacitor between the signal acquisition unit in the measuring state and the signal acquisition unit in a to-be-measured state.
