The Obama administration on Monday launched a formal review of its electronic intelligence gathering that has come under widespread criticism since leaks by a former spy agency contractor.
The Review Group on Intelligence and Communications Technologies will examine the technical and policy issues that arise from rapid advances in global telecommunications, the White House said in a statement.
The group will assess whether U.S. data collection "optimally protects our national security and advances our foreign policy while appropriately accounting for other policy considerations, such as the risk of unauthorized disclosure and our need to maintain the public trust," the statement said.
The high-level group of outside experts has 60 days to deliver its interim findings. A final report and recommendations are due on December 15.
A separate statement by Director of National Intelligence James Clapper confirmed the review. Neither the White House nor Clapper released details on the size or composition of the panel.
In a news conference at the White House on Friday, President Barack Obama vowed to improve oversight of surveillance and restore public trust in the government's programs.
The formal review is one of four measures unveiled by Obama, who said he had ordered a review of the surveillance programs before ex-National Security Agency contractor Edward Snowden leaked secret documents to The Guardian and The Washington Post.
Obama's other measures include plans to work with Congress to pursue reforms of Section 215 of the anti-terrorism Patriot Act that governs the collection of so-called "metadata" such as phone records, and reform of the secretive Foreign Intelligence Surveillance Court, which considers requests from law enforcement authorities on intelligence-gathering targets.
Obama also vowed to provide more details about the NSA programs to try to restore any public trust damaged by the Snowden disclosures.
Civil liberty groups demanded more details on Obama's plans, but WikiLeaks founder Julian Assange has called the announcement "a victory of sorts for Edward Snowden and his many supporters.
The Obama administration has vigorously pursued Snowden to bring him back to the United States to face espionage charges for leaking details of U.S. surveillance programs to the media. Snowden is now in Russia, where he has been granted a year's asylum.
