Abstract:
A liveness detection system comprises a controller, a video input, a feature recognition module, and a liveness detection module. The controller is configured to control an output device to provide randomized outputs to an entity over an interval of time. The video input is configured to receive a moving image of the entity captured by a camera over the interval of time. The feature recognition module is configured to process the moving image to detect at least one human feature of the entity. The liveness detection module is configured to compare with the randomized outputs a behaviour exhibited by the detected human feature over the interval of time to determine whether the behaviour is an expected reaction to the randomized outputs, thereby determining whether the entity is a living being.

Claim (Index 14):
A liveness detection system for regulating access to a computer system, the liveness detection system comprising:\n computer storage configured to store executable instructions; and one or more processors coupled to the computer storage for executing the instructions, the instructions being configured, when executed on the one or more processors, to implement the following:\n receiving from a user device a request for access to the computer system; \n receiving a moving image of a user's face captured with an image capture device of the user device, the moving image being captured as the user's face and the image capture device exhibit motion relative to each other; \n processing the moving image to determine an orientation of the user's face in the moving image, or to identify at least one forward reference point on the user's face and at least one rearward reference point on the user's face; \n receiving sensor data generated by a motion sensor coupled to the image capture device whilst capturing the moving image; and \n determining whether to grant the request for access based on a detected change in the orientation of the user's face or a detected movement of the forward reference point relative to the reward reference point in the moving image, wherein the request is granted only if the sensor data indicates the detected change in the orientation of the face or the detected movement of the references points correspond to motion of the image capture device.
