System and method for identification of false statements

Abstract

A method of detecting lie detection including the steps of first conditioning the subject to produce an involuntary physiological response triggered when the subject provides false statements; and secondly asking the subject to state whether each of series of statements presented to the subject are true. As the subject answers, the subject is monitored for the conditioned involuntary response. Detecting whether the subject is providing false statements is based on whether the involuntary response is observed during these answers. A system ( 19 ) for lie detection includes a computing device ( 21 ), a controlled ( 40 ), and at least one conditioning interface ( 42, 44 ).

1 .- 19 . (canceled)  
   
   
       20 . A system for detecting false statements made by a subject, the system comprising: 
 (a) a programmed computing device, the programmed computing device including a software module operative to; 
 (i) condition a subject to produce an involuntary physiological response pattern which is not a naturally occurring physiological response, when the subject states a false statement, and an opposite response pattern to a true statement; and to 
 A. present the subject with a plurality of questions, the answer to some of which are known in advance;  
 B. record the subject's answers to the plurality of questions while contemporaneously recording data related to the involuntary physiological responses; and  
 
 (ii) analyze the recorded data to determine whether the subject is providing false statements by comparing conditioned responses to the statements to the distribution of conditioned responses shown to known true and known false statements;  
   (b) an output device configured to receive data from the programmed computing device;    (c) a controller configured to be operated by the programmed computing device;    (d) at least one conditioning interface controllably operated by the controller, each conditioning interface further comprising: 
 i. an attachment structure for attaching the conditioning interface to a selected body part of the subject; and  
 ii. a physiological measurement device.  
   
   
   
       21 . A method of detecting false statements made by a subject comprising the steps of: 
 (a) conditioning the subject to produce an involuntary physiological response when the subject provides false statements;    (b) asking the subject to state whether a series of statements presented to the subject are true and monitoring for the involuntary response during the subject's answers; and    (c) detecting whether the subject is providing false statements based on whether the involuntary response is observed during the subject's answers.
