1. A method for identifying a false representation of a human face, the method comprising: receiving one or more data streams captured by one or more sensors sensing a candidate face; sequentially detecting various spoofing attempts in a cascading plurality of stages to determine that one or more of the data streams corresponds to the false representation of the human face, wherein the cascading plurality of stages are arranged in a predetermined order of decreasing commonality of the spoofing attempts beginning with more common spoofing attempts and ending with less common spoofing attempts; and based at least in part on determining that the one or more data streams corresponds to the false representation of the human face, outputting an indication of the false representation of the human face.
