Methods and systems for determining user liveness

摘要

A method determining user liveness is provided that includes calculating, by a device, eye openness measures for a frame included in captured authentication data, and storing the eye openness measures in a buffer of the device. Moreover the method includes calculating confidence scores from the eye openness measures stored in the buffer, and detecting an eye blink when a maximum confidence score is greater than a threshold score.

1. A method for determining user liveness comprising:
calculating, by a data capture device, eye openness measures for a frame included in captured authentication data and storing the eye openness measures in a buffer of the device, the buffer being configured to store eye openness measures calculated for frames included in the captured authentication data; calculating confidence scores from the eye openness measures stored in the buffer; determining, from the confidence scores, a maximum confidence score; and detecting an eye blink when the maximum confidence score is greater than a threshold score.
