Cell phone searches are a common law enforcement tool, but up until now, the public has largely been in the dark regarding how much sensitive information the government can get with this invasive surveillance technique. A document submitted to court in connection with a drug investigation, which we recently discovered, provides a rare inventory of the types of data that federal agents are able to obtain from a seized iPhone using advanced forensic analysis tools. The list, available here, starkly demonstrates just how invasive cell phone searches are—and why law enforcement should be required to obtain a warrant before conducting them.

Justice Department documents released today by the ACLU reveal that federal law enforcement agencies are increasingly monitoring Americans’ electronic communications, and doing so without warrants, sufficient oversight, or meaningful accountability.

The documents, handed over by the government only after months of litigation, are the attorney general’s 2010 and 2011 reports on the use of “pen register” and “trap and trace” surveillance powers. The reports show a dramatic increase in the use of these surveillance tools, which are used to gather information about telephone, email, and other Internet communications. The revelations underscore the importance of regulating and overseeing the government’s surveillance power.  (Our original Freedom of Information Act request and our legal complaint are online.)

A Justice Department chart released to the ACLU through a public records act request reveals the location data retention policies of the major mobile carriers. What's your carrier's policy?

We’ve been doing a fair amount of thinking about the implications of consumer wearable cameras like Google Glass, and I’m sure we’ll have more to say in this space on the subject. But meanwhile, we’re pleasantly surprised to report a very trenchant analysis of the technology’s implications for our privacy by none other than Michael Chertoff. Writing on CNN’s web page, the former DHS chief writes,

So, who owns and what happens to the user's [video] data? Can the entire database be mined and analyzed for commercial purposes? What rules will apply when law enforcement seeks access to the data for a criminal or national security investigation? For how long will the data be retained? ….

Even those who might be willing to forgo some degree of privacy to enhance national security should be concerned about a corporate America that will have an unrestricted continuous video record of millions.

What is to prevent a corporation from targeting a particular individual, using face recognition technology to assemble all uploaded videos in which he appears, and effectively constructing a surveillance record that can be used to analyze his life?

Chertoff says he’s inclined to think that government regulation may be needed. I haven’t seen Chertoff say anything about the threat of pervasive government surveillance, which would make him a kind of anti-libertarian on privacy—in favor of restricting corporations, but not the government. For the average, relatively powerless person trying to live their life, the threat comes from both directions.
