600 Billion Data Points Per Day? It’s Time to Restore the Fourth Amendment
Jeff Jonas has published an important post: “Your Movements Speak for Themselves: Space-Time Travel Data is Analytic Super-Food!”
More than you probably realize, your mobile device is a digital sensor, creating records of your whereabouts and movements:
Mobile devices in America are generating something like 600 billion geo-spatially tagged transactions per day. Every call, text message, email and data transfer handled by your mobile device creates a transaction with your space-time coordinate (to roughly 60 meters accuracy if there are three cell towers in range), whether you have GPS or not. Got a Blackberry? Every few minutes, it sends a heartbeat, creating a transaction whether you are using the phone or not. If the device is GPS-enabled and you’re using a location-based service your location is accurate to somewhere between 10 and 30 meters. Using Wi-Fi? It is accurate below 10 meters.
The process of deploying this data to markedly improve our lives is underway. A friend of Jonas’ says that space-time travel data used to reveal traffic tie-ups shaves two to four hours off his commute each week. When it is put to full use, “the world we live in will fundamentally change. Organizations and citizens alike will operate with substantially more efficiency. There will be less carbon emissions, increased longevity, and fewer deaths.”
This progress is not without cost:

Would PASS ID Really Save States Money?
The proposed PASS ID Act is a national ID just like REAL ID, and it threatens privacy just as much. Some argue that a national ID under PASS ID should be palatable, though, because it reduces costs to states.
But savings to states under PASS ID are not at all clear. Let’s take a look at the costs of creating a U.S. national ID.
The REAL ID Act, passed in May 2005, required states to begin implementing a national ID system within three years. In regulations it proposed in March 2007, the Department of Homeland Security extended that draconian deadline. States would have five years, starting in May 2008, to move all driver’s license and ID card holders into REAL ID-compliant cards.
The Department of Homeland Security estimated the costs for this project at $17.2 billion dollars (net present value, 7% discount). Costs to individuals came it at nearly $6 billion – mostly in wasted time. Americans would spend more than 250 million hours filling out forms, finding birth certificates and Social Security cards, and waiting in line at the DMV.
The bulk of the costs fell on state governments, though: nearly $11 billion dollars. The top three expenditures were $5.25 billion for customer service at DMVs, $4 billion for card production, and $1.1 billion for data systems and IT. Getting hundreds of millions of people through DMVs and issuing them new cards in such a short time was the bulk of the cost.
To drive down the cost estimate, DHS pushed the implementation schedule way back. In its final rule of January 2008, it allowed states a deadline extension to December 31, 2009 just for the asking, and a second extension to May 2011 for meeting certain milestones. Then states would have until the end of 2017 to replace all cards with the national ID card. That’s just under ten years.
Then the DHS decided to assume that only 75% of people would actually get the national ID. (Never mind that whatever benefits from having a national ID drop to near zero if it is not actually “national.”)
The result was a total cost estimate of about $6.85 billion (net present value, 7% discount). Individual citizens would still spend $5.2 billion worth of their time (in undiscounted dollars) on paperwork and waiting at the DMV. But states would spend just $1.5 billion on data and interconnectivity systems; $970 million on customer service; and $953 million on card production and issuance—a total of about $2.4 billion. (All undiscounted—DHS didn’t publish estimates for the final rule the same way it published their estimates for the proposed rule.)
Maybe these cost estimates were still too high. Maybe they weren’t believable. Or maybe Americans’ love of privacy and hatred of a national ID explains it. But the lower cost estimate did not slow the “REAL ID Rebellion.” Given the costs, the complexity, the privacy consequences, and the dubious benefits, states rejected REAL ID.
Enter PASS ID, which supposedly alleviates the costs to states of REAL ID. But would it?
At a Senate hearing last week, not one, but two representatives of the National Governors Association testified in favor of PASS ID, citing their internal estimate that implementing PASS ID would cost states just $2 billion.
But there is reason to doubt that figure. PASS ID is a lot more like REAL ID – the original REAL ID – in the way that most affects costs: the implementation schedule.
Review of the Big REAL ID Hearing
The Senate Homeland Security and Governmental Affairs Committee held a hearing yesterday on the REAL ID Act and the REAL ID revival bill, known as PASS ID. I attended and want to share with you some highlights.
Good News!
Little good came from the hearing, as it was primarily focused on how to get the states and people to accept a national ID. But there is some good news.
First, Department of Homeland Security Secretary Janet Napolitano declared REAL ID dead (much as I did in my testimony two-plus years ago). “DOA” is how she referred to it.
She also said that no state will be in compliance with REAL ID by the current December 31, 2009 deadline. This is important because a lot of people think that states doing anything about the security of drivers’ licenses and ID cards are complying with REAL ID.
Another highlight was the commentary of Senator Roland Burris (D-IL). He is a beleaguered outsider to the Senate and evidently wasn’t coached on the talking points around REAL ID and PASS ID. So he flat out asked why we shouldn’t just have “a national ID.”
Senator Susan Collins’ (R-ME) nervous smile was particularly noticeable when Burris asked why the emperor had no clothes. No one was supposed to talk about national IDs at this hearing! But that’s what PASS ID is.
REAL ID and PASS ID are two versions of the same national ID system, and nobody is denying it. That’s good news because the effort to rebrand REAL ID through PASS ID has failed.
Does the PASS ID Act Protect Privacy?
I’ve written about PASS ID here a couple of times before – first on whether or not it’s a national ID and, second, on the politics of this REAL ID revival bill. Now I’ll take a look at whether it fixes the privacy issues with REAL ID. Privacy is complicated. Buckle up.
The day the bill was introduced, the Center for Democracy and Technology issued a press release giving it a privacy stamp of approval.
“The PASS ID Act addresses most of the major privacy and security concerns with REAL ID,” said Ari Schwartz, Vice-President of CDT. The release cited four ways that PASS ID was an improvement over the bill it’s modeled on, REAL ID.
Interstate Data Sharing?
First, CDT said, PASS ID “[r]emoves the requirement that states ‘provide electronic access’ allowing every other state to search their motor vehicles records.” It’s technically true: The language from REAL ID directly requiring states to share information among themselves came out of PASS ID. But the requirements of the law will cause that information sharing to happen all the same.
Like REAL ID did, PASS ID would require states to confirm that “a person submitting an application for a driver’s license or identification card is terminating or has terminated any driver’s license or identification card” issued by another state.
How do you do that? You check the driver license databases of every other state. Maybe you do this by directly accessing other states’ databases; maybe you do this indirectly, through a “pointer system” or “hub.” But to confirm that you’re talking about the right person, you don’t just compare names. You compare names, addresses, pictures, and other biometrics.
Some Thinking on “Cyber”
Last week, I had the opportunity to testify before the House Science Committee‘s Subcommittee on Technology and Innovation on the topic of “cybersecurity.” I have been reluctant to opine on it because of its complexity, but I did issue a short piece a few months ago arguing against government-run cybersecurity. That piece was cited prominently in the White House’s “Cyberspace Policy Review” and — blamo! — I’m a cybersecurity expert.
Not really — but I have been forming some opinions at a high level of generality that are worth making available. They can be found in my testimony, but I’ll summarize them briefly here.
What Is “De-Identified”?
On a post at the TechLiberationFront blog, I discuss the fluidity of important concepts in information policy — and catch a friendly organization disagreeing with itself.
The upshot? “Until more intellectual groundwork is laid, information policy arguments before regulators, lawmakers, and courts will not rest on solid footing.”
E-Verify: The Surveillance Solution
The federal government will keep data about every person submitted to the “E-Verify” background check system for 10 years.
At least that’s my read of the slightly unclear notice describing the “United States Citizenship Immigration Services 009 Compliance Tracking and Monitoring System” in today’s Federal Register. (A second notice exempts this data from many protections of the Privacy Act.)
To make sure that people aren’t abusing E-Verify, the United States Citizenship and Immigration Services Verification Division, Monitoring and Compliance Branch will watch how the system is used. It will look for misuse, such as when a single Social Security Number is submitted to the system many times, which suggests that it is being used fraudulently.
How do you look for this kind of misuse (and others, more clever)? You collect all the data that goes into the system and mine it for patterns consistent with misuse.
The notice purports to limit the range of people whose data will be held in the system, listing “Individuals who are the subject of E-Verify or SAVE verifications and whose employer is subject to compliance activities.” But if the Monitoring Compliance Branch is going to find what it’s looking for, it’s going to look at data about all individuals submitted to E-Verify. “Employer subject to compliance activities” is not a limitation because all employers will be subject to “compliance activities” simply for using the system.
In my paper on electronic employment eligibility verification systems like E-Verify, I wrote how such systems “would add to the data stores throughout the federal government that continually amass information about the lives, livelihoods, activities, and interests of everyone—especially law-abiding citizens.”
It’s in the DNA of E-Verify to facilitate surveillance of every American worker. Today’s Federal Register notice is confirmation of that.
Computers Freedom & Privacy 2009
The Computers Freedom & Privacy conference is consistently one of the most interesting and forward-looking privacy conferences. This year, it’s at George Washington University in Washington, D.C. June 1-4.
I helped organize it this time, though by no means does the event skew libertarian. What it does is bring together people of all ideologies to discuss common concerns about the present and future state of privacy.
I’ll be speaking on a panel called “The Future of Security vs. Privacy” on Tuesday, June 2nd. Here’s the program page. And here’s the registration page if any of this whets your appetite.
