dryriver writes: The BBC reports: 'The UK branch of an American company — SAS Software — has developed a hi-tech software programme it believes can help detect and prevent potentially dangerous passengers and cargo entering the UK using the technique known as "risk profiling". So, what exactly is risk profiling and can it really reduce the risk of international terrorism? Risk profiling is a controversial topic. It means identifying a person or group of people who are more likely to act in a certain way than the rest of the population, based on an analysis of their background and past behaviour — which of course requires the collection of certain data on people's background and behaviour to begin with. When it comes to airline security, some believe this makes perfect sense. Others, though, say this smacks of prejudice and would inevitably lead to unacceptable racial or religious profiling — singling out someone because, say, they happen to be Muslim, or born in Yemen. The company making the Risk-Profiling Software in question, of course, strongly denies that the software would single people out using factors like race, religion or country of origin. It says that the programme works by feeding in data about passengers or cargo, including the Advanced Passenger Information (API) that airlines heading to Britain are obliged to send to the UK Border Agency (UKBA) at "wheels up" — the exact moment the aircraft lifts off from the airport of departure. Additional information could include a combination of factors, like whether the passenger paid for their ticket in cash, or if they have ever been on a watch list or have recently spent time in a country with a known security problem. The data is then analysed to produce a schematic read-out for immigration officials that shows the risk profile for every single passenger on an incoming flight, seat by seat, high risk to low risk.'
