1. A system for determining liveness and person-corresponding identification of a biometrically evaluated human, such system comprising: at least one secure clock arrangement configured to enable:
recording secure time stamps for (a) an emission event comprising emission of an electromagnetic signal set using an emitter arrangement, wherein such emission paints at least one human body position, and (b) a sensing event, using a sensor arrangement, of at least a portion of such emitted electromagnetic signal set's interaction with such at least one human body position, and measuring elapsed time between such emission event and a corresponding sensing event to establish a roundtrip time; and
a computing arrangement including at least one processor and associated memory, wherein such computing arrangement is configured to enable:
determining from such recorded secure time stamps, whether a roundtrip time timing anomaly event has occurred, wherein such elapsed time demonstrates whether a biometric presence spoofing event has occurred;
acquiring, using a biometric signal sensing and signal information processing arrangement for a biometric identification information registration process set, person-identifying pattern information from a biometrically evaluated human body feature arrangement;
measuring, using the at least one secure clock arrangement and the biometric signal sensing and signal information processing arrangement for the biometric identification information registration process set, timing of at least a dynamic biological process set occurring at a first position on a registering human's body and timing of one or more corresponding dynamic biological process sets occurring at one or more other positions on such registering human's body;
determining, from registration timing of such dynamic biological process sets, timing-relationship information of such one or more corresponding biological process sets occurring at such first position and one or more other positions on such registering human's body, wherein such timing-relationship information is configured for subsequent use during an authentication process set to determine whether a tangible object that is presented for biometric evaluation represents a living, physically present identified human;
deriving, at least in part, a (a) liveness-informing information set, and (b) person-identifying pattern information set, using information-set-respective measurement processes performed on the same or overlapping one or more body feature sets;
securely binding, for an authentication information process set regarding the tangible object presented as the human body feature arrangement, (a) such liveness-informing information and/or information from which it is derived, and (b) position-corresponding, person-identifying pattern information;
comparing similarity of (a) such liveness-informing information, and/or information from which it is derived, acquired for such biometric identification information registration process set to corresponding liveness-informing information acquired for such authentication process set, and such at least in part separate (b) person-identifying pattern information acquired for such biometric identification information registration process set to corresponding pattern information acquired for such authentication process set;
determining whether such authentication process set of a presented tangible object produces information that similarity matches information acquired from a registered living human-body-feature-arrangement by complying with required similarity matching one or more thresholds for such (a) liveness-informing information, and (b) person-identifying pattern information; and
securely governing a person identification related process set based on such authentication determination.
