Inside IBM's Patent Applications For Airport Security

Technology has potential to apply profiling of passengers, alerting officials to potential terminal and tarmac threats

Let's look at the patents in more detail. The profiling, off of sensor input, is described in patent application number 20090204695, filed last September. It's entitled "Unique Cohort Discovery From Multimodal Sensory Devices."

This patent application describes the use of a large number of sensors of all types -- chemical, biometric, etc -- around the airport perimeter, so data can be fed into a computer for analysis to detect threats.

Here's the relevant wording from the patent application:

"[Data processing parses the data to form attributes.] Attributes may include an individual's age, make and/or model of a vehicle, color of a hat, breed of a dog, sound of an engine, a medical diagnosis, a date of birth, a color, item of clothing, walking, talking, running, a type of food eaten, an identification of an item purchased.

An attribute that is an event may include eating, smoking, walking, jogging, walking a dog, carrying bags, carrying a baby, riding a bicycle, an engine running, a baby crying, or any other event.

Sensory data processing categorizes the events. . . For example, a type of event may include a pace of walking, a companion of the cohort, a time of day a cohort eats a meal, a brand of soda purchased by the cohort, a pet purchased by the cohort, a type of medication taken by the cohort, or any other event."

In terms of the sensors themselves, the system uses lots of diverse data-gatherers. From the patent application:

"Multimodal sensors comprises at least one of a set of global positioning satellite receivers, a set of infrared sensors, a set of microphones, a set of motion detectors, a set of chemical sensors, a set of biometric sensors, a set of pressure sensors, a set of temperature sensors, a set of metal detectors, a set of radar detectors, a set of photosensors, a set of seismographs, and a set of anemometers."

Angell told me that the system can even use olfactory sensors, which means they'll smell the environment. The patent application also variously mentions license plate recognition technology, face recognition software, and retina scanners. Data captured from video streams from airport cameras is also analyzed.

How does one computer process all this data fast enough to deliver a threat assessment quickly enough to airport security officials? Remember, the idea is to do the analysis in real time, as passengers are streaming through the terminal to board their flights. For a single box, this would be a processing challenge. However, the inventors envision using a small grid of computers connected over a network. This'd deliver ample power to do the real-time data crunching.

"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.
