Patent ID: 8218871

Claim:
A computer implemented method for detecting behavioral deviations in members of a cohort group, the computer implemented method comprising: identifying a member of the cohort group, wherein each member of the cohort group shares a common characteristic, and wherein the member is described using identification data, and further wherein the identification data includes: action data regarding the member's use of a web page, and device data regarding a computing device having a user interface and used by the member to interact with a data processing system associated with a transportation facility; retrieving respiratory metadata in real-time as the respiratory metadata is generated, wherein the respiratory metadata is associated with the member of the cohort group, wherein the respiratory metadata describes respiration associated with the member of the cohort group; identify patterns of respiratory changes using the respiratory metadata, wherein the respiratory metadata is analyzed to identify the patterns of respiratory changes; responsive to the patterns of respiratory changes indicating behavioral deviations in the member of the cohort group, identifying the member of the cohort group as a person of interest; analyzing audio data to identify human voices and phonetics of human speech to identify a voice print of the member of the cohort group, wherein the audio data describes non-respiratory characteristics of the member of the cohort group; comparing the voice print of the member of the cohort group to each voice print included in a group of known voice prints to locate one of the voice prints included in the group of known voice prints that matches the voice print of the member of the cohort group; and using the one of the voice prints included in the group of known voice prints that matches the voice print of the member of the cohort group to identify the member of the coherent group, wherein the action data includes page hits, sequence of hits, duration of page views, response to advertisements, and transactions made.
