"Computers aren't fast enough to do real-time modeling unless the paradigm shifts," Angell told me. "That's why this inference engine is a pretty big deal."
That shift is embedded in how inference engine is formulated. It uses rule sets, designed by Angell, Friedlander, and Kraemer, which enable it to fairly efficiently query 5 million or 10 million data cohorts, in a very short period of time.
Analyzing Eye Movements
There is another patent application in the group which takes the analysis of potential passenger threats to a whole 'nother level. It's entitled "Detecting Behavioral Deviations By Measuring Eye Movements." (Patent application number 2009232357, filed September 2009.) (Friedlander is not involved in this patent; it's Angell and Kraemer only.) From the filing:
"The ocular metadata [patterns of eye movement] is analyzed. . .In response to the patterns of ocular movements indicating behavioral deviations in the member of the cohort group, the member of the cohort group is identified as a person of interest."
Specifically, eye movement characteristics which are monitored and analyzed include: change in pupil size (dilation); direction of gaze; visual line of gaze (where someone is looking); and rate of blinking; and furtive glances.
Profiling is specifically addressed in this patent application, as follows:
"The profiled past comprises data that may be used, in whole or in part, for identifying the person, determining whether to monitor the person, and/or determining whether the person is a person of interest. Global profile data may be retrieved from a file, database, data warehouse, or any other data storage device. Multiple storage devices and software may also be used to store identification data 506. Some or all of the data may be retrieved from the point of contact device, as well. The profiled past may comprise an imposed profile, global profile, individual profile, and demographic profile. The profiles may be combined or layered to define the customer for specific promotions and marketing offers."
However, analysis of eye movements aren't the final word in indentifying passengers with potential ill intent. Patent application targets "Detecting Behavioral Deviations by Measuring Respiratory Patterns in Cohort Groups."
