The method includes measuring by at least one biometric sensor at least one biometric parameter of the screening subject. The method also includes scoring by a biometric analysis engine coupled to the biometric sensor the at least one biometric parameter measured of the screening subject. The method also includes generating by the biometric analysis engine biometric parameter feedback in such a way that a security screening agent either terminates or escalates the security screening of the screening subject based on the generated biometric parameter feedback. ## Claims ### Claim 1 A method for security screening a screening subject, comprising: measuring by at least one biometric sensor at least one biometric parameter of the screening subject; scoring by a biometric analysis engine coupled to the biometric sensor the at least one biometric parameter measured of the screening subject; and generating by the biometric analysis engine biometric parameter feedback in such a way that a security screening agent either terminates or escalates the security screening of the screening subject based on the generated biometric parameter feedback. ### Claim 2 (depends on 1) The method as recited in claim 1, wherein the at least one biometric parameter includes at least one of a heart/pulse rate, an eye movement, a facial temperature and a voice pitch variation of the screening subject. ### Claim 3 (depends on 1) The method as recited in claim 1, wherein measuring the at least one biometric parameter of the screening subject includes measuring the rate of change of at least one biometric parameter of the screening subject over a plurality of points in time. ### Claim 4 (depends on 1) The method as recited in claim 1, wherein scoring the at least one biometric parameter includes scoring the at least one biometric parameter using a graphical representation scoring scheme. ### Claim 5 (depends on 1) The method as recited in claim 1, wherein scoring the at least one biometric parameter includes scoring the at least one biometric parameter using an exceptions counting scoring scheme. ### Claim 6 (depends on 1) The method as recited in claim 1, wherein scoring the at least one biometric parameter includes scoring the at least one biometric parameter using a numerical value scoring scheme. ### Claim 7 (depends on 1) The method as recited in claim 1, wherein at least one of the biometric sensors is a passive sensor that does not makes physical contact with the screening subject when measuring the at least one biometric parameter of the screening subject. ### Claim 8 (depends on 1) The method as recited in claim 1, wherein measuring the at least one biometric parameter of the screening subject includes measuring the at least one biometric parameter of the screening subject in response to a stimulus to the screening subject. ### Claim 9 (depends on 1) The method as recited in claim 1, wherein generating biometric parameter feedback includes providing by at least one of visual and aural feedback. ### Claim 10 A system for security screening a screening subject, comprising: at least one biometric sensor that measures at least one biometric parameter of the screening subject; a biometric analysis engine coupled to the biometric sensor for scoring the biometric parameter of the screening subject measured by the biometric sensor, wherein the biometric analysis engine generates biometric parameter feedback in such a way that a security screening agent either terminates or escalates the security screening of the screening subject based on the generated biometric parameter feedback. ### Claim 11 (depends on 10) The system as recited in claim 10, wherein the at least one biometric sensor measures at least one of a heart/pulse rate, an eye movement, a facial temperature and a voice pitch variation of the screening subject. ### Claim 12 (depends on 10) The system as recited in claim 10, wherein the at least one biometric sensor measures the rate of change of at least one biometric parameter of the screening subject over a plurality of points in time. ### Claim 13 (depends on 10) The system as recited in claim 10, wherein the biometric analysis engine scores the at least one biometric parameter using a graphical representation scoring scheme. ### Claim 14 (depends on 10) The system as recited in claim 10, wherein the biometric analysis engine scores the at least one biometric parameter using at least one of an exceptions counting scoring scheme and a numerical value scoring scheme. ### Claim 15 (depends on 10) The system as recited in claim 10, wherein at least one of the biometric sensors is a passive sensor that does not makes physical contact with the screening subject when measuring the at least one biometric parameter of the screening subject. ### Claim 16 (depends on 10) The system as recited in claim 10, wherein the at least one biometric sensor measures the at least one biometric parameter of the screening subject in response to a stimulus to the screening subject. ### Claim 17 (depends on 10) The system as recited in claim 10, further comprising at least one of a visual and aural feedback component coupled to the engine for displaying biometric parameter feedback. ### Claim 18 A non-transitory computer readable medium having instructions stored thereon which, when executed by a processor, carry out a method for security screening a screening subject, the instructions comprising: instructions to measure at least one biometric parameter of the screening subject; instructions to score the at least one biometric parameter measured of the screening subject; and instructions to generate biometric parameter feedback in such a way that a security screening agent either terminates or escalates the security screening of the screening subject based on the generated biometric parameter feedback. ### Claim 19 (depends on 18) The non-transitory computer readable medium as recited in claim 18, wherein instructions to measure at least one biometric parameter of the screening subject include instructions to measure at least one a heart/pulse rate, an eye movement, a facial temperature and a voice pitch variation of the screening subject. ### Claim 20 (depends on 18) The non-transitory computer readable medium as recited in claim 18, wherein instructions to score the at least one biometric parameter measured of the screening subject include instructions to score the at least one biometric parameter measured of the screening subject to measure using at least one of a graphical representation scoring scheme, an exceptions counting scoring scheme and a numerical value scoring scheme.
