Methods for detecting truth utilizing biologic data
First Claim
1. A method for determining whether an action performed by a subject is true comprising the steps of:
- (i) fitting a subject with equipment to monitor Electroencephalographic data, the Electroencephalographic data including a plurality of frequencies in a frequency range, adjacent frequencies in said frequency range being separated by approximately one hertz;
(ii) presenting a stimulus to said subject, said stimulus designed to evoke the action performed by said subject, the action including providing an answer to a question, said stimulus being any one of a plurality of different questions;
(iii) recording said action;
(iv) recording, via a computing device, a first change of each of the plurality of frequencies between a first epoch and a second epoch as first change data, said first epoch occurring during presentation of said stimulus, and said second epoch occurring subsequent to presentation of said stimulus;
(v) recording, via said computing device, a second change of each of the plurality of frequencies between said second epoch and a third epoch as second change data, said third epoch occurring subsequent to said action;
(vi) repeating steps (ii) through (v) until a predetermined quantity of said stimulus of any one of the plurality of different questions have been presented to said subject and the actions performed by said subject in response to said predetermined quantity of said stimulus of any one of the plurality of different questions have been recorded, wherein a truth of a first set of said actions is known prior to performing step (iii) of the method and a truth of a second set of said actions is unknown prior to performing step (iii) of the method;
(vii) selecting an analysis frequency range;
(viii) for each action in said first set of said actions, determining a baseline value for each frequency of said plurality of frequencies in the analysis frequency range, said baseline value determined from said first change data;
(ix) for each of said action in said first set of said actions and said second set of said actions, creating a plurality of pair sets for each of said frequency of said plurality of frequencies in the analysis frequency range, each pair set of the plurality of pair sets includes a pair of first and second values, the first value of each pair is associated with the frequency of said plurality of frequencies, and the second value of each pair is associated with each other frequency for all other frequencies of the analysis frequency range other than the frequency of said plurality of frequencies associated with said pair set, said first value associated with said second change data for the frequency of said plurality of frequencies associated with said pair set, said second value associated with said second change data for each other frequency for all other frequencies of the analysis frequency range other than the frequency of said plurality of frequencies associated with said pair set;
(x) scoring each of said pair of each of said pair set of each of said action with a pair score;
(xi) assigning a match value to each of said pair of each of said pair set of each of said action based on a comparison of the pair score of said pair and said baseline value of the frequency of said plurality of frequencies associated with the pair set;
(xii) for each of said pair set of each of said action summing the match values of each of said pair of said pair set to create a total match value;
(xiii) for each of said action summing the total match values of each of said pair set of said action to generate a combined match value; and
(xiv) comparing the combined match value of each of said actions of said second set of actions to the combined match value of each of said actions of said first set of actions to determine whether each of the actions of said second set of actions performed by the subject is true.

Abstract
Systems and methods for detecting truth utilizing biologic data observed during various time periods occurring prior and subsequent to the presentation of a stimulus to a subject and/or prior and subsequent to a volitional action performed by the subject in response to the stimulus. A method for creating a truth or lie scale involving: presenting a stimulus designed to evoke an action to a subject; monitoring a first change in biologic data between a first epoch and a second epoch, the first epoch occurring during presentation of the stimulus, and the second epoch occurring subsequent to presentation of the stimulus; monitoring a second change in biologic data between a second epoch and a third epoch, the third epoch occurring subsequent to the action performed by the subject; and analyzing the monitored data to create the truth or lie scale.
