A civil liberties group that previously had criticized the administration said the latest changes show a strong commitment to protecting privacy. Still, the Electronic Frontier Foundation said there's room for improvement. Administration officials said they are open to that.

"We think that this is a great first step (and) would be thrilled to see more organizations, both public and private, follow their lead."
