Abstract: Actions are authorized by computing a confidence score that exceeds a threshold. The confidence score is based on a match between metadata about requests and fields in corresponding database records. The confidences score weights matches by the dependability of the metadata for authentication. The confidence score is further based on the closeness of a sample of speech audio to a stored voiceprint. Additional identification may be required for authorization. The confidence score requirement may be relaxed based on identification in a buffer of recent action requests.
