corporal_clegg writes "According to this story on FoxNews, in March Delta Airlines will begin using a federal database that incorporates credit history and bank records in an effort to identify potential security threats. The federal system - CAPPS II (Computer Assisted Passenger Prescreening System) - will assign a "threat level" to passengers based upon information in the database and other criteria, such as whether the individual is on government watch lists. 'CAPPS II will collect data and rate each passenger's risk potential according to a three-color system: green, yellow, red. When travelers check in, their names will be punched into the system and the boarding passes encrypted with the ranking.' The scary thing is that no one really knows which databases the government will use or how long the records will remain. Slashdot covered this story in September 2002, and it now seems that the first airline is ready to give it a try. In addition to the links in the previous Slashdot article, a good background on CAPPS II can be found here."
Actually, the last story we did on passenger profiling
was just a week or two ago.
