Palantir, a data-mining company created by Peter Thiel, is aiding government agencies by tracking American citizens using the War on Terror, Bloomberg reports. From the report:
The company's engineers and products don't do any spying themselves; they're more like a spy's brain, collecting and analyzing information that's fed in from the hands, eyes, nose, and ears. The software combs through disparate data sources -- financial documents, airline reservations, cellphone records, social media postings -- and searches for connections that human analysts might miss. It then presents the linkages in colorful, easy-to-interpret graphics that look like spider webs.
The U.S. Department of Health and Human Services uses Palantir to detect Medicare fraud. The FBI uses it in criminal probes. The Department of Homeland Security deploys it to screen air travelers and keep tabs on immigrants. Police and sheriff's departments in New York, New Orleans, Chicago, and Los Angeles have also used it, frequently ensnaring in the digital dragnet people who aren't suspected of committing any crime.
