An outside review panel is recommending that the Obama administration make wide-ranging changes to the government's surveillance programs.
The report, which has 46 specific recommendations, was released to the public Wednesday after President Barack Obama met with the panel members.
White House officials say the president and his national security team will study the document and decide which recommendations should be implemented.
The report calls for limits on the collection of American telephone and Internet metadata, as well as reforms to the National Security Agency (NSA).
Public disclosure of the NSA spying programs this year by exiled former NSA contractor Edward Snowden sparked an outcry over the government's intelligence programs.
One of the panel's recommendations is that President Obama appoint a civilian NSA director when the current director, General Keith Alexander, steps down next year. The panel also said the position should be one that requires Senate confirmation.
There has never been a civilian head of the NSA.
