    摘要： Registering a biometric template with a computing device includes receiving a first scan of a biometric feature from a biometric sensor. The first scan includes first biometric data. The computing device extracts two or more distinct elements of the biometric feature and writes a biometric template to a memory. The first characterization data for each of the two or more distinct elements is recorded in the biometric template. After recording the first characterization data in the biometric template, the computing device receives an additional scan of the biometric feature from the biometric sensor. The additional scan includes second biometric data. The computing device validates the biometric template against the second biometric data. After validating the biometric template, the biometric template is updated with second characterization data. The second characterization data is associated with two or more additional distinct elements of the biometric feature contained in the second biometric data.

    摘要： Disclosed is a biometric information acquisition system and a processing method thereof. The biometric information acquisition system comprises a transparent substrate; a light source; a photoelectric conversion device, which is located at one side of the transparent substrate with the light source, receives light reflected by the transparent substrate and generates electrical signals; a processing device for obtaining biometric information based on the electrical signals. At least a portion of the transparent substrate is made of flexible material, and fits a predetermined portion of an organism on the other side of the transparent substrate based on a curved interface, therefore, ambient light incident to the photoelectric conversion device is reduced, an interference caused by the ambient light is reduced, accuracy of acquiring biometric characteristic information is improved. Because fitting with the curved interface can increase contact area, more biometric characteristic information of the predetermined portion can be obtained.

    摘要： A multi-segment pixel matrix, a sensor or device, a system, and a method, for biometric sensing, are provided. Such a device or system includes a sensor comprising a pixel matrix having two or more pixel arrays as separate segments logically divided in the pixel matrix. The pixel matrix may include both thermal sensing pixels and capacitive sensing nodes. The device or system may include a plurality of application-specific intergrade circuits (ASICs) coupled to the sensor. Each ASIC is configured to capture image data of a biometric pattern measured by at least one pixel array. Each pixel array is independently driven and scanned by one or more of the plurality of the ASICs. The device or system further includes a microcontroller unit coupled to the plurality of ASICs and are used to process the image data and/or control operation of the system. Such a sensor can be a fingerprint sensor.
