User Profiling bei den Airlines


-.-. --.- -.-. --.- -.-. --.- -.-. --.- -.-. --.- -.-. --.-

Jetzt geht es systematisch los mit dem Data-Mining in den vielen Einträgen,
die bei den Airlines von uns gespeichert sind. Ab nun kann man darauf
gefasst sein, dass am Gate plötzlich ganz spezifische Fragen gestellt
werden.

Federal aviation authorities and technology companies will soon begin testing
a vast air security screening system designed to instantly pull together every
passenger's travel history and living arrangements, plus a wealth of other
personal and demographic information.

The government's plan is to establish a computer network linking every
reservation system in the United States to private and government
databases. The network would use data-mining and predictive software to
profile passenger activity and intuit obscure clues about potential threats,
even before the scheduled day of flight.

It might find, for instance, that one man used a debit card to buy tickets for
four other men who sit in separate parts of the same plane -- four men who
have shared addresses in the past. Or it might discern an array of unusual
links and travel habits among passengers on different flights.

Those sorts of details -- along with many other far more subtle patterns
identified by computer programs -- would contribute to a threat index or score
for every passenger. Passengers with higher scores would be singled out for
additional screening by authorities.

As described by developers, the system would be an unobtrusive network
enabling authorities to target potential threats far more effectively while
reducing lines at security checkpoints for most passengers. Critics say it
would be one of the largest monitoring systems ever created by the
government and a huge intrusion on privacy.

Although such a system would rely on existing software and technology, it
could be years before it is fully in place, given that enormous amounts of data
would need to be integrated and a structure would need to be established for
monitoring passenger profiles.

At least one carrier, Delta Air Lines, has been working with several
companies on a prototype. Northwest Airlines has acknowledged that it is
talking with other airlines about a similar screening system. Federal
authorities hope to test at least two prototypes in coming months or possibly
sooner, according to government and industry sources familiar with the effort.
