The high-tech system would use thousands of "intelligent" cameras and computer processors that can recognize people's faces and retinas and then compare the facial information with databases such as terrorist watch lists, sources told the New York Post in a story published Monday.
Security measures at the 16-acre site, scheduled to be completed next year, include the cameras, along with infrared and heat sensors that can be modified to include explosive and radiation detection, the officials said.
The Port Authority also is authorizing the use of "artificial intelligence" computers that can track the behavior of people to determine how to spot "unusual movements" that can be flagged, the Post said.
Behavioral Recognition Systems will set up most of the system, estimated to cost tens of millions of dollars.
While not speaking specifically about the World Trade Center system, John Frazzini, president of the Houston-based Defense Department contractor, said the system doesn't retain personal information and no security monitors are installed in private areas such as restrooms.
The Twin Towers of the old World Trade Center were destroyed in the Sept. 11, 2001, terror attacks.
