(CNN) - Angry Birds is one of the most popular game applications, with more than 1 billion downloads. But according to the New York Times, it may be used by the NSA to track the people playing it.
The Times reported a classified program focuses on "so-called leaky apps that spew everything from users' smartphone identification codes to where they have been that day." The NSA is trying to collect and store that data, the report stated.
"If you want to track what people do on the internet you have to move to apps; I think that's what is driving the NSA to track apps," said James Lewis of the Center for Strategic and International Studies.
In response to the story, the NSA stated any implication that foreign intelligence collection was focused on smartphone or social media communications of everyday Americans was not true.
The White House also responded.
"We are not interested in the communications of people who are not valid foreign intelligence targets," said White House Press Secretary Jay Carney.
The report was based on documents said to be leaked by former NSA contractor Edward Snowden. In one document, which could not be verified by CNN, the effort is described as a golden nugget.
Information that could be collected included location of users, networks they connect to, websites visited, buddy lists and downloaded documents.
"This would need really tight controls to make sure they weren't taking advantage of it," Lewis said.
