"Later in discussing proposals for national information sharing, Harman said, "We already have in a sense a private sector based information sharing system -- credit card companies run it. And the good news is, they're capable of collecting a lot of information and popping out things using state-of-the art technology.'' She used the example that the credit card companies come to know a pattern of a customer's charges so well that they can identify when the card is being used fraudulently and query the customers. "That's a private based system that works well. There's also a private based system that's abused," she said. She did not elaborate on abuses." |
