Introduction: why Behaviour Detection?

The concept of behaviour detection, or Behaviour Risk Assessment, as a method of detecting suspicious individuals continues to occupy the headlines. As a recognized layer of security screening that has been successfully deployed in Israel and other countries, it is part of considerable efforts worldwide focusing on reforming the existing legacy approach to security into a more risk-based system (read about Focus on Intent).

In recent years, two international bodies, IATA and ICAO, have been leading the way by advocating a transition from the current “one-size-fits-all model” of security to a model where passengers are screened based on established or perceived levels of risk. As part of a risk-based model, all passengers would be divided into Low, High, Unknown groups according to information available about them to security personnel in advance (e.g. Passenger Name Record) and identification of any suspicious indicators in real time. Various countries, such as the US, Canada, UK, France and Australia have been studying the subject very closely including in pilot projects and research studies to determine best practices and/or validate the approach.

A feature article in the September 2013 issue of "Passenger Terminal World" is dedicated to the coverage of Behaviour Detection as one of the risk-based screening methods applied in modern mass transit (e.g. airports) settings.

CHI Security's Michael Berk was interviewed by this leading industry magazine to provide insights into this highly specialized trade. Read the feature article here on-line or in the digital format here 
(see page 18).

Note: the authors have incorrectly associated the Passenger Behaviour Observation pilot program with Transport Canada, as oppose to the Canadian Air Transport Security Authority. We asked them to update this (as well as the full name of our company) but the issue went to print already... 

Today's news are filled with articles citing another GAO report issued yesterday and entitled "TSA Could Strengthen Oversight of Allegations of Employee Misconduct". 

Apparently the rate of complaints against TSA screening officers have increased by 26% in the past three years. The report said 3,408 misconduct allegations were filed against TSA workers last year, up from 2,691 in 2010.  Many of the charges for screening and security-related incidents pertain to violating standard operating procedures, including not conducting security or equipment checks, and allowing patrons or baggage to bypass screening. 

While the increase in allegations (if they're based on true foundations) is lamentable, with over 1.6 million of screened passengers per day and over 56,000 Transportation Security Officers involved, the numbers cited must be taken in a proper context. 

Just came across an article in LA Times entitled "Randomizers' could ward off airport profiling accusations" stating that one of the reasons for deploying them "is so TSA officers can't be accused of profiling passengers when they direct some fliers to a line for regular screening and others to a line for a faster, less-intrusive search". This is peculiar, I thought.
