摘要： Secure communications are provided between a user computing device and a server computing device. An enrollment request is received from a user computing device that is configured via a distributed client software application and is processed. The enrollment request is usable to enroll the user computing device in a network and includes an encrypted partial initial biometric vector associated with a user. An authentication request is processed that is subsequently received that includes an encrypted partial second biometric vector and that is associated with a user of the user computing device. A comparison of the encrypted partial initial biometric vector and the encrypted partial second biometric vector is performed, and a value representing the comparison is generated and transmitted to the user computing device. The user computing device is authenticated where the value is above a minimum threshold.

摘要： Technologies are presented herein in support of a system and method for performing iris identification and verification using mobile devices. Embodiments of the present invention concern a method for authenticating a user with a mobile device that includes steps for capturing imagery of a user's face, analyzing the imagery to identify the portion of the image depicting the user's eyes and segmenting the eye image to isolate the iris image data and encoding the iris image data in iris template. The present disclosure further describes authenticating the user based on the encoded iris template and 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 eyes and analyzing the captured images for indications of liveness based on reflection characteristics depicted in the imagery.

摘要： Technologies are presented herein in support of system and methods for user recognition using motion sensor data. Embodiments of the present invention concern a system and method for capturing motion sensor data using motion sensors of a mobile device and characterizing the motion sensor data into features for user recognition. The motion sensor data of a user is collected by the motion sensors of a mobile device in the form of a motion signal. One or more sets of features are extracted from the motion signal and a subset of discriminative features are then selected. The subset of features is analyzed, and a classification score is generated to classify the user as a genuine user or an imposter user.

摘要： Methods and systems for disentangling discriminative features of a user of a device from motion signals and authenticating a user on a mobile device are provided. In at least one aspect of the methods and systems, each captured motion signal is divided into segments. The segments are then converted into translated segments using one or more trained translation algorithms. The segments and translated segments are then provided to a machine learning system. Discriminative features of the user are then extracted from the segments and translated segments with the processor using the machine learning system that applies one or more feature extraction algorithms.

摘要： Technologies are presented herein in support of system and methods for user recognition using motion sensor data. Embodiments of the present invention concern a system and method for partitioning a captured motion signal of a user into segments. One or more sets of features are extracted from the segmented motion signal by applying a plurality of feature extraction algorithms to the segments, where the feature extraction algorithms include Convolutional Vision Transformers (CVT) and convolutional gated recurrent units (convGRU) model algorithms. A subset of discriminative features are selected from the sets of extracted features. The subset of features is then analyzed, and a classification score is generated to classify the user as a genuine user or an imposter user.

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.
