The FBI is pressing Internet service providers to record which Web sites
customers visit and retain those logs for two years, a requirement that law
enforcement believes could help it in investigations of child pornography
and other serious crimes.

FBI Director Robert Mueller supports storing Internet users' "origin and
destination information," a bureau attorney said at a federal task force
meeting on Thursday.

As far back as a 2006 speech, Mueller had
*called*<http://news.cnet.com/2100-7348_3-6126877.html>for data
retention on the part of Internet providers, and emphasized the
point two years later when *explicitly asking
Congress*<http://news.cnet.com/8301-13578_3-9926803-38.html>to enact a
law making it mandatory. But it had not been clear before that
the FBI was asking companies to begin to keep logs of what Web sites are
visited, which few if any currently do.

The FBI is not alone in renewing its push for data retention. As CNET *
reported* <http://news.cnet.com/8301-13578_3-10446503-38.html> earlier this
week, a survey of state computer crime investigators found them to be nearly
unanimous in supporting the idea. Matt Dunn, an Immigration and Customs
Enforcement agent in the Department of Homeland Security, also expressed
support for the idea during the task force meeting.

Greg Motta, the chief of the FBI's digital evidence section, said that the
bureau was trying to preserve its existing ability to conduct criminal
investigations. Federal regulations in place since at least 1986
*require*<http://law.justia.com/us/cfr/title47/47-3.0.1.1.1.0.2.7.html>phone
companies that offer toll service to "retain for a period of 18
months" records including "the name, address, and telephone number of the
caller, telephone number called, date, time and length of the call."

At Thursday's *meeting
(PDF)*<http://www.ntia.doc.gov/frnotices/2010/FR_OSTWGMtg_100111.pdf>of
the Online Safety and Technology Working Group, which was created by
Congress and organized by the U.S. Department of Commerce, Motta stressed
that the bureau was not asking that content data, such as the text of e-mail
messages, be retained.

"The question at least for the bureau has been about non-content
transactional data to be preserved: transmission records, non-content
records...addressing, routing, signaling of the communication," Motta said.
Director Mueller recognizes, he added "there's going to be a balance of what
industry can bear...He recommends origin and destination information for
non-content data."

Motta pointed to a 2006
*resolution*<http://www.politechbot.com/2006/10/23/data-retention-endorsed/>from
the International Association of Chiefs of Police, which called for
the
"retention of customer subscriber information, and source and destination
information for a minimum specified reasonable period of time so that it
will be available to the law enforcement community."

Recording what Web sites are visited, though, is likely to draw both
practical and privacy objections.

"We're not set up to keep URL information anywhere in the network," said
Drew Arena, Verizon's vice president and associate general counsel for law
enforcement compliance.

And, Arena added, "if you were do to deep packet inspection to see all the
URLs, you would arguably violate the Wiretap Act."

Another industry representative with knowledge of how Internet service
providers work was unaware of any company keeping logs of what Web sites its
customers visit.

If logs of Web sites visited began to be kept, they would be available only
to local, state, and federal police with legal authorization such as a
subpoena or search warrant.

What remains unclear are the details of what the FBI is proposing. The
possibilities include requiring an Internet provider to log the Internet
protocol (IP) address of a Web site visited, or the domain name such as
cnet.com, a host name such as news.cnet.com, or the actual URL such as *
http://reviews.cnet.com/Music/2001-6450_7-0.html*<http://reviews.cnet.com/mp3-players/>.


While the first three categories could be logged without doing deep packet
inspection, the fourth category would require it. That could run up against
opposition in Congress, which
*lambasted*<http://news.cnet.com/8301-13578_3-9993554-38.html>the
concept in a series of hearings in 2008, causing the demise of a
company, NebuAd, which pioneered it inside the United States.

The technical challenges also may be formidable. *John
Seiver*<http://www.dwt.com/people/JohnDSeiver>,
an attorney at Davis Wright Tremaine who represents cable providers, said
one of his clients had experience with a law enforcement request that
required the logging of outbound URLs.

"Eighteen million hits an hour would have to have been logged," a staggering
amount of data to sort through, Seiver said. The purpose of the FBI's
request was to identify visitors to two URLs, "to try to find out...who's
going to them."

A Justice Department representative said the department does not have an
official position on data retention.

Online Safety and Technology Working Group, though after the law enforcement
representatives spoke.*
