Congress asks more questions about TSA blacklists

The “No-Fly” and “Selectee” lists managed by Federal agencies through the joint Watch List Advisory Council (WLAC) aren’t the only blacklists and watchlists that are used to determine who is given US government permission to board an airline flight, and how they are treated when they fly.

Senior members of relevant House and Senate Committees are asking overdue questions about the blacklists created and used by the Transportation Security Administration (TSA) to target selected travelers for special scrutiny, surveillance, and searches when they fly.

The TSA’s Secure Flight program is used to determine, on the basis of identifying and itinerary information from ID documents and airline reservations, what Boarding Pass Printing Result (BPPR) to send to the airline for each would-be passenger. The ruleset included in the Secure Flight algorithm includes list-based and profile-based Quiet Skies rules created by the TSA itself, independent of the interagency No-Fly and Selectee travel blacklists.

These Quiet Skies rules are used to flag certain airline passengers as “Selectees” to be searched more intrusively at TSA checkpoints (even if they aren’t on the interagency Selectee list), and to assign Federal Air Marshals (FAMs) to follow, watch, and file reports on their activities in airports and on flights. A secret alert is sent to FAMs, based on airline reservations, 72 hours before each planned flight by a person on the Quiet Skies list.

The Quiet Skies program was implemented secretly in 2012. “In March 2018,” according to a later report on the Quiet Skies program by the DHS Office of Inspector General (OIG), “in addition to enhanced checkpoint screening, TSA began surveillance (observation and collection of data) of Quiet Skies passengers beyond security checkpoints, as part of its Federal Air Marshal Service’s (FAMS) Special Mission Coverage flights.

The No-Fly list and profile-based no-fly rules are used in the Secure Flight travel control  and surveillance algorithm to determine who is allowed to fly. The Selectee and Quiet Skies lists and rules are used to  determine who to search and surveil when they fly.

The Quiet Skies program came to light later in 2018 when FAM whistleblowers went to the Boston Globe with their complaints that the wrong travelers were being targeted, mis-prioritizing which flights FAMs were being assigned to. These FAM whistleblowers complained, that, for example, anyone identitied from airline reservations as having traveled to Turkey was put on the Quiet Skies list and had a FAM assigned to each US flight they took for the next several months, including domestic flights. Travelers’ reports of being followed through airports (presumably by FAMs) and subjected to more intusive searches at TSA checkpoints after trips to Turkey supported these allegations.

The TSA initially declined to confirm the existence of the Quiet Skies program. But in response to questions from Congress and follow-up reprting by the Globe, the TSA released a belated Privacy Impact Assessement (PIA) for Quiet Skies in 2019. However, that PIA specified none of the Quiet Skies rules and gave no demographic or other information about who those rules had targeted.

Additional descriptions of the program, including the flowchart above, but still not including any of the Quiet Skies rules, were included in a critical DHS OIG report on the program in 2020.

Since January 6, 2021, there has been a new round of complaints by travelers and disgruntled FAMs that participants in the activities that day at the US Capital have been put on the No-Fly, Selectee, and/or Quiet Skies lists.

This month a redacted version was made public of a formal complaint to the DHS OIG by a FAM who says his wife was put on the Quiet Skies list and “targeted for FAMS ‘Special Mission Coverage’ simply because she attended President Trump’s January 6, 2021 speech at the ellipse in Washington, D.C.” FAMs also said that former US Representative and Presidential candidate Tulsi Gabbard has been put on the Quiet Skies list because of her role in the January 6, 2021 events. When she read those reports, Gabbard said that, “The whistleblowers’ account matches my experience” of disprate treatment at TSA checkpoints.

We’ve been unable to confirm or disprove these reports. But we find them plausible and — whether or not they are true — indicative of fundamental problems in these arbitrary, secret, extrajudicial schemes for making decisions about the exercise of our right to travel by common carrier and to be free from unreasonable searches and seizures.

Canada copies US “Secure Flight” air travel controls

While we were watching US election returns, our neighbors to the north were adopting new travel regulations that incorporate some of the worst aspects of the US system of surveillance and control of air travel, and in some respects go even further in the wrong direction.

Canadian authorities don’t generally want to be seen as imitating the US or capitulating to US pressure. There was no mention in the official analysis of the latest amendments to the Canadian regulations of the US models on which they are based. But according to the press release this week from Public Safety Canada, the latest version of the Canadian Secure Air Travel Regulations  which came into force this week for domestic flights within Canada as well as international flights to or from Canada include the following elements, each of which appears to be based on the US Secure Flight system:

  1. All air travelers will be required to show government-issued photo ID. The Canadian ID requirement to fly is now explicit, unlike the de facto ID requirement that the US Department of Homeland Security is attempting to impose and already wrongly enforcing, in some cases, without statutory or regulatory authority. The Canadian rules appear to reflect the authority to deny passage to air travelers without ID that the DHS has sought, but has not yet been granted, in the US.
  2. Fly/no-fly decision-making will be transferred from airlines (making binary fly/no-fly decisions on the basis of a no-fly list provided by the government) to a government agency. After receiving information about each passenger from the airline, Public Safety Canada will transmit a permission messages to the airline with respect to each would-be passenger on each flight,  with a default of “not permitted to board” if no message is received by the airline from the government. Exactly this change was made in the US through the Secure Flight regulations promulgated in 2008. This change serves two purposes for the government: (A) it provides a basis for building positive real-time government control over boarding pass issuance into airline IT infrastructure, converting every airline check-in kiosk or boarding-pass app into a virtual government checkpoint that can be used to control movement on any basis and for any reason that the government later chooses, and (B) it enables the switch from blacklist-based no-fly decision-making to more complex and opaque real-time algorithmic pre-crime profiling  based on a  larger number of factors.
  3. Air travelers in Canada will be required to provide the airline  with their full name, gender, and date of birth, as listed on government-issued ID, and airlines will be required to enter this data in each reservation and transmit it to the government 72 hours before the flight or as soon as the reservation is made, whichever comes first. All of this is exactly as has bene required for flights within the US since the coming into force of the DHS Secure Flight regulations. This additional information about each passenger enables the government to match passengers’ identities, in advance, to other commercial and government databases, and thus to incorporate a much wider range of surveillance and data mining into its profiling algorithms.
  4. Travelers will be able to apply to the government for a “Canadian Travel Number” which, if issued, they can enter in their reservations to distinguish themselves as whitelisted people from blacklisted people with similar names and/or other similar personal data.  This Canadian Travel Number is obviously modeled on the “redress number” incorporated in the US Secure Flight system. The goal of this “whitelist number” is to reduce the complaints and political embarrassment of the recurring incidents of innocent people with similar names, including  children, being mistakenly identified as blacklisted people, and denied boarding on Canadian flights. The problem, of course, is that this does nothing to help the innocent people who are correctly identified as having been blacklisted by the government, but who were wrongly blacklisted in the first place.

As our Canadian friends at the  International Civil Liberities Monitoring Group put it in a statement this week:

These regulations do not address the central, foundational problems that plague Canada’s No Fly List system and will continue to result in the undermining of individuals’ rights as they travel….

The Canadian government had a solution from the beginning, and they still do: abolish the No Fly List. If someone is a threat to airline travel or to those in the region they are traveling to, charge them under the criminal code and take them to court where they can defend themselves, in public.

It’s time to be done with secret security lists once and for all.

What China calls “social credit”, the US calls “risk assessment”

A viral video of an announcement on a Chinese high-speed train and a series of reports (here and here) on NPR have prompted a surge of interest this week in China’s “social credit” system:

Dear passengers: People who travel without a ticket, behave disorderly, or smoke in public areas will be punished according to regulations, and the behavior will be recorded in individual credit information system. To avoid a negative record of personal credit, please follow the relevant regulations and help with the orders on the train and at the station.

Despite unwarranted comparisons to US financial credit scores, “social credit” scoring in China is used by the government and para-statal entities, not just private companies, and not just for financial decision-making.

One of the NPR stories as well as a report last month by the Australian Broadcasting Co. include interviews with people who discovered they were barred by the Chinese government from travel on high-speed trains as a result of “social credit” scores, regardless of their ability to pay for tickets.

Dystopian? Yes.

Unjust? Yes?

“It can’t happen here?” No.

It already happens here, every day, to everyone who travels by airline or engages in bank or credit card transactions.

You may not realize it until you are mysteriously unable to obtain a boarding pass or complete a financial transaction, but each of these activities is already subject to secret, permission-based, extrajudicial prior restraint by the US government.

The default is “no”.  Since a little over 10 years ago, US Federal regulations have forbidden any airline from issuing a boarding pass unless and until it has sent the would-be traveler’s itinerary and identifying information to the DHS and has received back an individualized, per-passenger, per-flight, permission-to-travel message from the DHS. The DHS generates a secret “risk score” for each passenger, which determines how closely they are searched and questioned, whether the airline is instructed to call the police when they try to check in, and other aspects of how they are treated.

Even before airlines or banks get to the point of consulting the government, “carrier sanctions” and similar sanctions against financial institutions give them a financial incentive to err on the side of saying “no”, not “yes”.

You don’t have to be on a government blacklist for your air travel or financial transactions to be blocked by the US government or by airlines or banks acting at the government’s behest. There are multiple air travel blacklists (euphemistically and inaccurately called “watchlists”), but no-fly and transaction-processing decisions are also made in real time, on the basis of algorithmic “pre-crime” predictions (euphemistically and misleadingly called “risk assessments”, despite the lack of any evidence of a correlation between these scores and actual “risk”).

What China calls “social credit scoring”, the US calls “risk-based screening”.

Government blacklists and real-time pre-crime policing are being applied to control a growing range of activities of daily life. But air travel and financial transactions are the areas where the US government already has a fully deployed and operational real-time “social credit” system in which private service providers are seamlessly integrated with government agencies to surveil and control our everyday activities.

The question isn’t whether the US should have a “social credit” system — it already does — but whether it should be expanded to more aspects of our lives, or rolled back.

It can happen here. It is happening here. It will continue to happen here until we stop it.

China’s social credit system provides a useful object lesson in the three essential preconditions for a system of ID-based surveillance and control. We can block or impede the expansion of such schemes by undermining any of these three legs of the tripod:

  1. ID requirements to travel or engage in other transactions or activities — If you travel, pay, or act anonymously,  your individualized “score” can’t be used to control you. China’s “social credit” system is enabled by requirements to show government-issued ID to open a bank or mobile payment account or purchase a SIM card.  You can only rent a shared bicycle in China through an app, not by cash, and you can’t use the app without an ID-linked mobile phone and ID-linked payment account. So even if you travel around a Chinese city by shared bicycle, you can be tracked. Travel anonymously, and use cash or other anonymous forms of payment.
  2. Collection of ID-linked transaction and position data  — Chinese “social credit” scores and US “risk assessments” are based on travel, movement, and transaction histories. Some of this data is collected through biometric identification, primarily automated  facial recognition. Other data is “ingested” by the government from commercial databases such as travel reservations and financial transactions. Private companies can and should resist requests for this data, but can’t be counted on to do so. No airline, for example, has ever challenged government demands for warrantless access to the entirety of their reservation database, including free-text derogatory internal comments by front-line reservation and customer-service staff that are imported directly into permanent DHS files used for “risk” scoring. Once personally identified or identifiable data is collected, it’s almost impossible to resist demands for government access made in the name of “security”.  Any data that is collected about you can and will be used against you. The only real way to oppose this mass surveillance is #DoNotCollect. Just say no to requests for information, for consent to search, or for sharing of data with the government.
  3. Government control of movement, activity, and transactions — A key step in the implementation of the “social credit” system for air travel was the installation (at a cost to the airline industry of at least US$2 billion) of the control lines that transformed a reporting (i.e. surveillance) system into a “pre-crime” control system. It’s critical to defend against having our Constitutional and human rights redefined as privileges to be exercised only by prior permission of the government —  as the right to travel by common carrier has already been. Demand that restrictions on the exercise of rights be based on evidence-based court orders, not pre-crime fantasies.

As for the specific Chinese examples of travel by high-speed train, Amtrak, like the operators of Chinese trains, is a para-statal government-charterted corporation. In 2014, we made a FOIA request to Amtrak for records of Amtrak’s sharing of passenger data with the DHS and other law enforcement agencies. Amtrak has been releasing a trickle of responsive records, as we’ve been reporting. But Amtrak’s response remains incomplete, and this is now the oldest pending unanswered request in Amtrak’s FOIA queue.

How many air travel blacklists does the US have?

[Click image for full-sized version.]

Heavily redacted records released by the Transportation Security Administration (TSA) last month, more than six years after they were requested by the Electronic Privacy Information Center (EPIC), give fragmentary clues to the answer to an important question: Just how many air travel blacklists does the US government have?

Is the TSA checking domestic airline passengers for warrants?

[Entities and data flows involved in decision-making (“vetting”) about travelers. Larger image, PDF with legend.]

The latest annual report on data-mining by the Department of Homeland Security contains a disturbing hint that the TSA may have gotten the ability to include checks for warrants and police “wants” in its “vetting” of passengers on domestic airline flights.

This would turn airline check-in counters and kiosks and TSA checkpoints for domestic air travel into dragnet suspicionless warrant checkpoints.

According to page 16 (page 19 of the PDF) of the newly-released 2016 DHS Data Mining Report, “An annex to this report containing Sensitive Security Information (SSI) about Secure Flight’s use of ATS-P is being provided separately to the Congress.”

What data from ATS, to which the TSA didn’t already have independent access,  is being used by the TSA as part of Secure Flight? For what purpose?

In the diagram above (larger image, PDF with legend), the solid green line shows the transfer of data from the FBI’s “National Criminal Information System” (NCIC) criminal history database to CBP’s “Automated Targeting System” (ATS) for use in “vetting” international airline passengers. The dashed green line shows the newly-disclosed transfer of ATS data to the “Secure Flight” system used by the TSA to “vet” domestic airline passengers. This could allow the TSA to check all domestic airline passengers for warrants and “wants” listed in NCIC, as CBP already has the ability to dos for all international airline passengers on flights to or from the US.

There is no explicit mention in the public portion of the DHS report of TSA use of NCIC data for decision-making (“vetting”) about domestic air travelers. But as the diagram above shows, almost all of the other data contained in ATS is already available directly to the TSA for use in Secure Flight. It’s not clear what data from ATS, other than criminal history data imported to ATS from NCIC, the TSA doesn’t already obtain directly without needing to get it from ATS.

Records of arrest warrants in NCIC are often inaccurate, as we have noted before. It’s especially common for the issuance of a warrant to be reported to the FBI for inclusion in NCIC, but for the later cancellation of that warrant not to be reported to NCIC. NCIC contains hundreds of thousands, perhaps millions, of listings for warrants that are no longer valid. Using TSA “vetting” of domestic airline passengers as a suspicionless dragnet for “wanted” individuals would inevitably result in the detention and arrest of many innocent people at TSA checkpoints on the basis of inaccurate NCIC data.

Normally, warrant checks are permissible only on the basis of reasonable articulable suspicion that a person has committed a crime. The current CBP checks of international travelers for warrants, police “wants”, and investigative “lookouts” have been permitted only as part of a judicially-created border exception to the 4th Amendment to the US Constitution. There is no comparable “airport exception” to the 4th Amendment that would allow suspicionless dragnet warrant checks on domestic travelers by the TSA. Travel is not an inherently suspicious activity. It’s the exercise of a Constitutional and human right, and cannot in itself be the basis for warrant checks.

Members of Congress should look closely at the secret annex to the 2016 DHS Data Mining Report, and question the DHS and TSA as to whether they are using, or intend to use, data obtained from NCIC (directly or indirectly through ATS or otherwise) to conduct warrant checks on domestic air travelers.

If any of our readers has information about someone being identified for arrest on an outstanding warrant (valid or invalid) on the basis of TSA “screening”, rather than on the basis of an independent police warrant check based on reasonable suspicion, please let us know.

What does Donald Trump’s election mean for our work?

We endorsed neither Hillary Clinton, Donald Trump, nor any other candidate for elected office. So what does the presumptive election of Donald Trump as President of the U.S. — when the electors cast their ballots on December 19, 2016, and the votes are counted on January 6, 2017 — mean for the work of the Identity Project?

First and foremost, it means that our work, and the need for it, will continue — as it has under previous administrations, both Democratic and Republican.

Human and Constitutional rights are, by definition, no more dependent on the party affiliation of the President, if any, than on our own. Freedom is universal. Our defense of the right of the people to move freely in and out of the U.S. and within the country, and to go about our business, without having our movements tracked and our activities logged or having to show our papers or explain ourselves to government agents, has been and will remain entirely nonpartisan.

We will continue to criticize those who restrict our freedoms and infringe our rights, regardless of their party, just as we have criticized the actions of both the Obama and Bush administrations and of members of Congress and other officials of both parties, many of whom remain in power despite the changes at the top.

Attacks on our liberty have been, and remain, just as bipartisan as our resistance to them. This is especially true of the imperial power which the Presidency has been allowed to accrue, and which is exercised through Presidential proclamations, executive orders, and the secret law (or, to be more accurate, lawlessness) of Federal agency “discretion”. Those who acquiesced in the expansion of Presidential power and executive privilege because they thought that it would be used to their benefit by a President of their own party have only themselves to blame if that power is later used against them by a new President of a different party, or without allegiance to a traditional party hierarchy.

Many of the most imminent ID-related threats are those that arise from existing laws or extrajudicial administrative practices, the limits of which — in the absence of legislative or judicial oversight and checks and balances — are set solely by executive order. Where President Trump can make changes to ratchet up repression, to register and track both U.S. and foreign citizens, and to monitor and control our movements within the country and across borders, with the stroke of a pen, we don’t expect that he will hesitate to wield the power he has inherited to govern by issuing public decrees or by giving secret orders to his minions.

In some of these cases, Federal officials and the homeland-security industrial complex of contractors, confident that the incoming occupant of the White House will bless their efforts to anticipate has desires, may take action even before they are ordered to do so. This seems especially likely, in our area of concern, with respect to (1) the DHS implementation schedule and requirements for the REAL-ID Act,  (2) the TSA’s longstanding desire to enforce and eliminate exceptions to a de facto ID requirement for air travel that lacks any basis in statute and contravenes the U.S. Constitution and international law, and (3) expanded use of ID and surveillance-based pre-crime profiling (President-to-be Trump calls it “extreme vetting”) as the basis for control of movement, especially across borders.

We will be watching closely and reporting on signs of activity on all these fronts, some of which are already visible.

Now more than ever, we need your support — not just helping us to defend your rights, but asserting your rights and taking direct action to defend them yourselves. “The limits of tyrants are prescribed by the endurance of those whom they oppress.”

We invite you to join us in our continued resistance to all lawless attacks from any and all sides on our Constitution, our freedom, and our human rights.

Proposed laws would expand travel controls from airlines to passenger railroads

Legislation has been introduced in both the USA and Belgium to subject rail travelers to the same sorts of travel surveillance schemes that are already being used to monitor and control air travelers.

If these proposals are enacted into law, passenger railroads would be required to collect and enter additional information such as passport or ID numbers and dates of birth (not currently required or routinely included in US or European train reservations) in Passenger Name Records (PNRs), and transmit rail travel itineraries and identifying information about passengers to the government, in advance.

As is already the case for all airline travel in the USA, including domestic travel, railroads would be forbidden to allow any passenger to board unless and until the railroad receives an explicit, affirmative, individualized, per-passenger, per-flight permission-to-board message (“Boarding Pass Printing Result”) from the government.

In both the USA and Belgium, the proposed legislation would create legal conflicts with civil liberties and human rights, and practical conflicts with railroad business processes and IT capabilities.

“CAPPS IV”: TSA expands profiling of domestic US airline passengers

Under color of a vestigial provision of Federal law related to an airline passenger profiling program that was discontinued more than four years ago, and applying the name of that program (and attempting to apply the same legal mandate) to an entirely new scheme, the TSA is adding a new, additional layer of passenger profiling to its pre-crime system for domestic airline flights within the United States.

The existence and TSA-mandated implementation of the new so-called “Computer-Assisted Passenger Prescreening System (CAPPS)” was first disclosed publicly in an obscure posting this Monday on the DHS website and an equally obscure notice published the same day in the Federal Register.   According to both documents, the new CAPPS scheme has been under development since at least 2013, in secret collaboration between the TSA, the inter-departmental National Counterterrorism Center (NCTC), airlines, and private contractors.

What was the old CAPPS? What is the new CAPPS? And what does this mean for the rights of travelers?

Answering these simple-seeming questions requires understanding the history of government-mandated airline passenger profiling in the US and the shell game of labels that the government has applied to profiling schemes, as well as careful parsing of this week’s abstruse and uninformative (to the uninitiated) official notices.

“Travelers, say bon voyage to privacy”

We talked at length with Watchdog investigative reporter Dave Lieber for his column in today’s Dallas Morning News: Travelers, say bon voyage to privacy.

Lieber hits the nail on the head by calling out how few travelers realize that the U.S. government is keeping a permanent file of complete mirror copies of their reservations:

Did you know that when you buy an airline ticket and make other travel reservations, the government keeps a record of the details?

If airlines don’t comply, they can’t fly in the U.S., explains Ed Hasbrouck, a privacy expert with the Identity Project who has studied the records for years and is considered the nation’s top expert.

Before each trip, the system creates a travel score for you…. Before an airline can issue you a boarding pass, the system must approve your passage, Hasbrouck explains….

The idea behind extensive use of PNRs [Passenger Name Records], he says, is not necessarily to watch known suspects but to find new ones.

Want to appeal? “It’s a secret administrative process based on the score you don’t know, based on files you haven’t seen,” Hasbrouck says….

Hasbrouck says: “You can’t keep files on everybody in case you want some dirt on them. That’s what J. Edgar Hoover did. We’ve been through this before in this country. Think of all the ways those files targeted innocent people and were misused. People’s lives were destroyed on the basis of unfounded allegations.

“Do we want to go back to that?”

For those whose curiosity has been piqued, here are links to more about this issue:

The FAQ, What’s in a Passenger Name Record (PNR)?, includes links to examples of PNR data, templates to request your travel history and PNR files from DHS, and information about our lawsuit against DHS to try to find out what files it has about us and how it has used and “shared” them.

Requirements for airlines to send passenger data to the government, and receive individualized (per-passenger, per-flight) permission from the government before issuing a boarding pass, are contained in two separate sets of DHS regulations: Secure Flight for domestic flights and the Advance Passenger Information System (APIS) for international flights. (More about the APIS regulations.)

The system of “pre-crime” profiling and assigning scores to all air travelers was discussed in recent government audit reports and at a Congressional hearing last month, and in a front-page story in the New York Times, in which we were quoted, last year.

There’s a good overview of the government’s travel surveillance and control process in a talk by Edward Hasbrouck of the Identity Project that was broadcast on C-SPAN</a> last year. The slides from that talk include diagrams of the system and examples of PNR data and other government files about travelers.

What happens if you fit the DHS profile even though you aren’t a threat?

In a self-assessment published this week by the DHS on the integration of DHS programs for surveillance, profiling, and control of airline passengers (the TSA’s Secure Flight for domestic flights and the CBP’s Automated Targeting System for international flights), the DHS says it is reducing to 15 years the length of time for which DHS will retain logs of people who were singled out for special treatment as “matches” on the basis of (secret) DHS profiling algorithms, but who were “ultimately determined not to be a threat.”

The DHS will still keep its TECS log entries for the trip itself, and will be able to retrieve a new copy of your PNR (airline reservation record) from the airline or CRS (database hosting company) at any time, even if DHS has deleted its previous mirror copy or copies.  But the DHS will purge its record of having wrongly flagged you as a suspect if you’ve stayed out of trouble for the subsequent 15 years:

Records created about an individual associated with a confirmed or possible match to a watchlist that require additional analysis in the ATS case management module ATS-Targeting Framework (TF) will be retained for 15 and seven years respectively in ATS if the individual is ultimately determined not to be a threat. However, COP information maintained only in ATS that is linked to a specific case or investigation will remain accessible for the life of the law enforcement matter to support that activity and other enforcement activities that may become related. In addition, CBP may include information in TECS on individuals who may need additional scrutiny.

The DHS privacy impact self-assessment confirms that the DHS has shifted from blacklist/whitelist matching to real-time profiling and scoring as its methodology for making fly/no-fly and “intrusiveness of search” decisions.  The self-assessment also makes explicit that the reason for long-term retention by DHS of mirror copies of the commercial airline records is to enable subsequent pre-crime data mining:

It is over the course of time and multiple visits that a potential risk becomes clear. Travel records (including historical records), are essential to assist CBP officers with their risk-based assessments of travel indicators and identifying potential links between known and previously unidentified terrorist facilitators. Analyzing these records for these purposes allows CBP to effectively identify suspect travel patterns and irregularities.
