摘要： A method for verifying the identity of a user is provided that includes generating, by a computing device, a parameter for each processed frame in a video of biometric data captured from a user. The parameter results from movement of the computing device during capture of the biometric data. Moreover, the method includes generating a signal for the parameter and calculating a confidence score based on the generated signal and a classification model specific to the user. The classification model is generated from other signals generated for the parameter. Furthermore, the method includes verifying the identity of the user as true when the confidence score is at least equal to a threshold score.

摘要： A method for detecting user liveness is provided that includes selecting first and second images from a sequence of images. The first and second images are captured under different illumination conditions. The method further includes locating feature calculation windows in corresponding positions on the first and second images. Each window includes a first area and a second area. Moreover, the method includes calculating, by a computing device, a feature value for each window position based on pixels, within the windows located at the position, from the first and second images. Furthermore, the method includes calculating a feature vector from the feature values, calculating a confidence score from the feature vector, and determining the sequence of images includes images of a live user when the confidence score is equal to or greater than the threshold score.

摘要： A method identifying a client computer system is provided that includes requesting over a network, by a client computer system, to access a server computer system operating an online service. The client computer system includes an input device. Moreover, the method includes granting access, by the server computer system, to the client computer system, and capturing input data from the client computer system, by the server computer system. The input data is generated by activity of the input device. Furthermore, the method includes calculating temporal differences from the captured input data, a distribution from the temporal differences, and a clustering tendency and a clustering period for the distribution from the captured input data. Additionally, the method includes identifying, by the server computer system, the client computer system when the calculated clustering tendency and clustering period match corresponding data for a client computer system stored in the server computer system.

摘要： A method for capturing biometric data is provided that includes capturing a user biometric characteristic positioned freely in space in a video with a mobile device while moving the user biometric characteristic in response to at least one instruction. The video includes frames that each includes a user biometric characteristic image. Moreover, the method includes obtaining frames from the video and determining obtained video frames that include an optimally positioned user biometric characteristic image. The optimally positioned user biometric characteristic image is user biometric data usable for generating accurate authentication transaction results to authenticate the user. The method also includes storing the optimally positioned user biometric characteristic image included in a determined video frame in the mobile device.

摘要： A method of capturing biometric data is provided that includes activating a security application in a device. The security application is activated by an operator of the device and is configured to cause the device to display an outline image. Moreover, the method includes displaying the outline image in a stationary position on a display of the device, positioning desired biometric data proximate the device such that the desired biometric data appears as a biometric image on the device display, and monitoring the outline and biometric images shown on the device display. Furthermore, the method includes positioning the device and the desired biometric data to better align the outline and biometric images when the outline and biometric images do not align and capturing the desired biometric data from an individual after approximately aligning the outline image with the biometric image.

摘要： A method for splitting a digital signal using prosodic features included in the signal is provided that includes calculating onset value locations in the signal. The onset values correspond to stress accents in the signal. Moreover, the method includes splitting, using a processor, the signal into a prosodic unit candidate sequence by superimposing the stress accent locations on the signal, and processing the sequence to include only true prosodic units.

摘要： A method of text-based authentication that accounts for positional variability of biometric features between captured biometric data samples includes capturing biometric data for a desired biometric type from an individual, and processing the captured biometric data to generate a biometric image and a biometric feature template. A selected conversion algorithm is executed by superimposing a positional relationship medium on the biometric image. The positional relationship medium includes a plurality of cells textually describable with words derivable from the positional relationship medium. The positions of biometric features are permitted to vary in overlapping border regions within the positional relationship medium. The method also includes identifying the position of at least one biometric feature within the overlapping border regions and generating a plurality of words for the at least one biometric feature.
