WASHINGTON (AP) — White House counselor John Podesta says a review of how the government and private sector use large sets of data has found that such information could be used to discriminate against people on issues such as housing and employment.

The review is expected to be released within the next week, and Podesta discussed it with The Associated Press.

"Big data" is everywhere.

It allows mapping apps to ping cellphones anonymously and determine in real time what roads are the most congested. But it also can be used to target economically vulnerable people.

President Barack Obama asked for this review in January. That's when he called for changes to some of the National Security Agency's surveillance programs that amass large amounts of data belonging to Americans and foreigners.
