The Privacy and Civil Liberties Oversight Board is almost done conducting a review on the National Security Agency's investigation of unauthorized call records, FCW reported Monday.
The review tackles the technical problems that have caused NSA's Call Detail Records program to collect an excessive amount of data.
Ben Huebner, chief civil liberties and privacy officer under the Office of the Director of National Intelligence, said the review is now going through the final approval processes.
NSA collects communication records in accordance with the 2015 USA Freedom Act for surveillance purposes. Huebner said the program has been collecting too much information due to data inaccuracies.
"[NSA] was only authorized to receive the two-hop information, but if there was an error with that first hop, all of those additional records that came in on that second hop would be overcollection and certainly a compliance incident," he said at the Cato Institute conference.
