Congress is considering putting restrictions on the Transportation Security Administration's (TSA) new, high-priority system for reviewing background information on airline passengers. But TSA chief James Loy says he welcomes the oversight.

TSA is replacing the Computer Assisted Passenger Prescreening System (CAPPS) that airlines now use with a more sophisticated second-generation model, known as CAPPS II, that will be government owned and operated.

When passengers make reservations, they will be asked for their name, address, date of birth and phone number. That information will be used to search private databases to determine if a passenger is a "rooted member of the community."

Each passenger will be assigned a score representing how likely the person is to pose a security threat.
