Swiss Intelligence Oversight Body Cites Problems with Database
The GPDel expressed concern about the overall quality of the data held in the database. Based on its inspection of various sample entries, the GPDel found instances where the individuals or incidents entered into the database were not serious enough to warrant inclusion as well as instances where data had expired but had not been deleted. The GPDel also opined that the database suffered from the systematic entry of incorrect data due to a flaw in internal entry guidelines. Additionally, it suspected that many of the 80,000 third person entries did not meet the legal requirements that warranted entry in the database.
According to an article in the Neue Zürcher Zeitung, only about 5% of the entries concern Swiss citizens and only 12.2% are Swiss residents. These facts have perhaps prompted the Federal Commission for Migration Issues to inquire whether the database has had any bearing on the issuance of resident permits, as reported by the NZZ (citing an interview on Swiss Radio DRS).
The report is available in French here and in German here.

News: US Government Accountability Office on the Cost of Full Body Scanners
The audit agency said TSA estimates each unit costs about $170,000, meaning it would cost about $300 million to buy 1,800 units, enough to cover about 60 percent of screening checkpoint lanes at the highest-priority commercial airports. Each scanner requires three people to operate. Based on the administration's request for $219 million to hire 3,550 TSA staffers next year alone, GAO estimates it will cost $2.4 billion overall to staff the machines over eight years.
They also have raised the issue of effectiveness, noting in particular that the operation of such machines on the 25 of December would not have stopped Umar Farouk Abdulmutallab. The House Homeland Security Committee is due to have a hearing on the proposed use of the machines this afternoon.
Detecter partner Mathias Vermeulen has a piece summarising the growing opposition to full body scanners over at the Lift.

Focus on Full-Body Scanners
Operation
There are full-body scanners that have been developed that use x-rays (generally referred to as “backscatter” scanners), but the scanners that have attracted so much attention in the media lately are millimeter wave scanners. These units rely on waves that lie somewhere between microwaves and infrared light on the frequency spectrum. According to this article from the Austrian newspaper, Der Standard, human bodies naturally emit millimeter waves. In order to produce a clear image, however, millimeter wave scanners using the so-called “active method” bombard the body with additional millimeter waves. These waves are able to pass through clothing, paper, and thin plastics but not through human bodies. Thus, the reception of these waves as they bounce back from the body can be used to construct a picture of the outer surface of the body and reveal unusual objects hidden beneath clothing. Apparently, “passive method” scanners, which merely read naturally occurring millimeter wave emissions, have been developed and used in some airports (See e.g., this article from heise online (in German)). However, I can imagine that these scanners may not produce images of the same clarity and/or may require longer screening times.
Are the “active method” machines safe?
The jury is still out. The German Federal Office for Radiation Protection indicated in an article in the sueddeutsche that existing wave research has tended to concentrate on testing the health risks of waves used in mobile devices such as mobile phones. Therefore, there isn’t a great deal of research available on the health impact of these millimeter wave frequencies. What scientists seem to agree on is that the waves won’t ionize atoms within the body like X-rays and thus won’t damage cells the way ionizing radiation does. Millimeter waves will, however, warm the tissues that they strike. What tissues they strike depends on the wavelength of the wave. These waves encompass a range of frequencies beginning somewhere around 10 gigahertz and ending somewhere around 10 terahertz. According to the article in the sueddeutsche, waves at the lower end of that spectrum could penetrate a few millimeters into the skin. I don’t know whether current models of scanners tend to use waves around one specific frequency, whether they always send out waves at various frequencies, or whether they have frequency settings which may be adjusted by the operator. This article on the German Wikipedia, however, indicates that different frequencies may be useful for detecting different materials. For one official of the German Federal Office for Radiation Protection, the “big question” is whether the waves could cause other biological effects in addition to warming—such as bringing components of skin cells into oscillation or causing changes within the blood as it flows through surface capillaries. He adds, however, that these questions are “pure speculation.” For me, the question that always arises with radiation exposure is whether more frequent exposure will pose risks that don’t present themselves in simple, short-term testing. It’s not inconceivable that frequent flyers may have to pass through such scanners 2-3 times within a 10 hour period on several occasions within a single month.
Privacy issues
There are obvious privacy issues connected with a scanner that produces images of the naked body. But apart from revealing intimate parts of the anatomy and physical anomalies that an individual might not want to bare, the scanners might also reveal details such as that the person has had a colostomy, has incontinence problems, or is menstruating. Cognizant of the privacy issues, developers of these scanners aimed to develop solutions that would address them. Initially, the idea was to place the person reviewing the images from the scanner in a separate location than where the actual scanning takes place. Thus, the person viewing the image would be unable to see “in the flesh” the individual with whom that image was associated. Additionally, algorithms were introduced to automatically blur faces (an example of an image with facial blurring can be seen here). In this way, the image reviewer would be unable to link the image to an actual person. Of course, the problem is that colostomy pouches, feminine hygiene pads, devices that deliver medications or insulin, and the like still might prompt an embarrassing or uncomfortable confrontation with security personnel at the screening location.
Scan Tech: The Next Generation?
What if we could remove the image reviewer? Could we design software to do the reviewing for us and indicate where suspicious things crop up? One project led by Loughborough University that we heard about at the first DETECTER meeting in Birmingham was aiming to develop just such a program—one that could distinguish a bottle from a handgun carried in the hand of an individual captured in video recordings. We also heard from one of the manufacturers of a millimeter wave scanner who indicated that they were working to develop that kind of technology, but that it hadn’t yet matured to where it could be implemented.
But news reports today suggest that this “second generation” technology is now available and pictures have emerged from Amsterdam’s Schiphol airport which feature just the kind of generic, impersonal gingerbread-man-like graphic that we had talked about in Birmingham (an example is available here with a close-up here). Areas of the body that hold suspicious objects are then highlighted on the graphic, so that security personnel can conduct a search of that area. Unlike the original setup, the system in Amsterdam displays the computer-generated “results” directly to the personnel manning the scanner.
There are a few things to point out about this second generation of scanning. First of all, just because pictures in the media show displays with the gingerbread man figure doesn’t necessarily mean that the viewing of the “raw” image—so to speak—has been eliminated altogether. Secondly, I’m a bit skeptical as to how well this software will perform as compared with a human viewer. It seems like getting the optimal set of algorithms would take countless test runs and tweaking, and I imagine that there would still be things that the software would miss but that a human reviewer would pick up on, as well as things that the software would catch that a human reviewer would miss or identify as harmless (like colostomy pouches). Which brings us to the third point—that the software-based solution might result in more uncomfortable confrontations with security than with the human reviewer. Lastly, the software would rely on raw data from the scanner, and it would still be theoretically possible for someone to “reconstruct” the image if that someone had access to the raw data.
Access and Data Storage
The Electronic Privacy Information Center (EPIC) has obtained documents from the US Transportation Security Administration pertaining to the procurement of full-body scanners (For links, see this post on the LIFT). The procurement specifications indicate that the TSA has put significant thought and planning into the implementation of these systems, including privacy safeguards. Nonetheless, EPIC points out that, despite TSA’s public assurances that scan images could not be saved, the documents reveal that the systems would be able to store images when in “test mode.” Granted, TSA foresees different levels of access to these systems. In this case, only TSA headquarters, maintenance technicians, and so-called “super users” would be able to put a scanner system into test mode, and image storage would be disabled during normal operation, according to the TSA’s procurement specifications (see pp. 4, C-1). A note in Appendix C of these specifications indicates that super user access for a particular system would be disabled once the system was installed, suggesting that these super users would be representatives of the equipment vendor responsible for the initial setup of the system. Thus, for normal operation on passengers, that would officially leave just TSA headquarters and technicians who would be able to place the system in test mode in which images would be stored.
Nonetheless, this news does indicate that the systems have storage capacity. The question is how much. By limiting the storage capacity to only a few images, the risk of negative privacy impact could be minimized. Of course, the flip-side of not saving images is that it rules out the possibility of performing ex post re-evaluations. Suppose another incident like that on Christmas Day occurs, but the attempted bomber had gone through a full-body scanner. Would security specialists want to take another look at that person’s scan image (supposing they can identify it) to see if they can learn something from the mistake?
Open or Closed Network(s)?
Related to the issue of access is the question of whether the system represents a closed system or is linked or exposed to broader communication networks such as the internet. At first glance, I don’t see too many reasons why these systems would need to be connected to the internet. The image reviewer would not need to read e-mail or access websites to do his or her work. One advantage of allowing internet communication is that it would permit quick, uniform updating of changes to user accounts from a central office. Thus, if an image reviewer left his or her position with the TSA, that former employee’s access could be lifted for all scanner systems throughout the country more or less simultaneously. It might also be desirable to have uniform access at all airports so that image reviewers could be shifted around according to need. On the other hand, these same objectives might be achieved through other systems, such as physical access controls—using an employee ID card or the like—that would prevent unauthorized personnel from entering image viewing facilities. However, the ability to access remotely every system’s system log would allow auditing to take place on a more efficient basis. Thus, this point would speak in favor of network access. But I’m not convinced that the burden of conducting audits on the local level would necessarily outweigh the benefit of the added security. Alternatively to local audits, audit data (which does not include image data) could be exported using flash drives or a temporary network connection.
There are indications that the TSA is opting for the fully linked system. The TSA’s procurement specifications for a “Whole Body Imager” state that the system should support a minimum user database of 10,000 accounts (p. 17). That’s an extremely high number for any single airport. Additionally, the TSA’s operational requirements call for the system to have an “802.11X compatible” network interface (p. 11). IEEE 802.11 denotes a set of wireless network protocols. Thus, the inclusion of this functionality within the operation requirements indicates that the TSA would like to ensure that these systems are capable of sending and receiving wireless communications. The operational requirements also call for the network interface to be “configurable with an IP address” (Ibid.). This requirement suggests that there would be internet access. Lastly, the documentation requires that the system be able to interface with “STIP” (Security Technology Integrated Program) (Ibid.), which appears to be the TSA’s enterprise architecture for allowing communication between detection technology instruments in the field and central headquarters (See this entry on the US government’s “IT Dashboard”).
Summing Up
In sum, health-related risks are probably minimal, but currently unknown. In light of this fact, why not simply use passive systems that rely on the human body’s own millimeter wave emissions to eliminate any possible health risk? In terms of privacy protections, replacing the human reviewer with software algorithms may reduce the privacy impact for many but increase it for others. Eliminating network access would also substantially lower the risk that scan images end up distributed where they don’t need to be but could hamper other aspects of operations. All of these considerations come on top of the questions concerning the scanners’ effectiveness and necessity (See the last full paragraph of this earlier post and this from the LIFT).

Comment: Christmas Day Plot, Part I (Update)
The article also features an interesting quote from a “senior Homeland Security official” who indicated that “in-depth vetting only begins once the flight manifest has been generated, a few hours before takeoff.” This statement suggests that passenger name records are not submitted on a rolling basis as reservations are made but only once the list of passengers on any one flight has been relatively solidified.

Comment: Christmas Day Plot, Part I
As news of the attempted attack began to unfold, reports began to roll in that the individual behind the attempt, Umar Farouk Abdulmutallab, had raised a number of red flags which should have resulted in enhanced screening, potentially his detention for further investigation, or--as some have suggested--the denial of an entry visa for the US. First it was revealed that Abdulmutallab had been included in the National Counterterrorism Center’s TIDE (Terrorist Identitites Datamart Environment) database (more on TIDE in Part II) (See this story from CBS). Then, it came to light that Abdulmutallab’s father had approached US State Department officials in Nigeria with concerns that his son had “fallen under the influence of ‘religious extremists’ in Yemen” (See this story from CBS). According to a report from CBS News, this information was forwarded to officials in Washington (In fact, it may have been the basis for Abdulmutallab being entered in TIDE). Apparently, however, no flags were attached to Abdulmutallab’s US visa, and the CBS report suggests that US officials who had received information relating the father’s concerns did not realize that the individual in question had been issued a multiple-entry visa by the US Embassy in London that was valid from June 16, 2008 to June 12, 2010. Lastly, it has been reported that the NSA had identified communications among Al Qaeda members in Yemen concerning a plot involving a Nigerian (See articles here and here).
The Obama administration called for two reviews: one quick review of flight screening procedures and technologies, the other a more in-depth review of the terrorist watch list system in use in the US. President Obama has promised that the results of the reviews will be revealed in public reports in the near future. It will be interesting to see to what extent the details of what happened at each stage of Abdulmutallab’s journey will be released. For me, the following questions come up: 1) Were any personal data pertaining to Abdulmutallab submitted to the TSA before he boarded the flight from Nigeria? 2) What security procedures did Abdulmutallab undergo in Lagos (or Ghana)? 3) Was Abdulmutallab subjected to security procedures at Schiphol? It would be particularly interesting to know whether he underwent a full-body scan (such scanners are evidently in common use at Schiphol) (more on full-body scanning below)?
In this case, it isn’t clear to what extent fault can be found with US authorities. Clearly mistakes were made, but even if all the information on Abdulmutallab had come together and resulted in an operational decision, measures stemming from that decision would have to have been taken in Nigeria or the Netherlands in order to have been effective. The incident may primarily reflect the lack of uniform and coordinated procedures at the international level. The US has expressed the desire to receive passenger name records for all passengers who have booked flights to the US. Yet, the question arises as to how many airlines indulge that desire and with what level of accuracy. This requirement has been particularly contentious within the EU. However, given the fact that Abdulmutallab had booked passage with a US-based air carrier for the final leg of his journey, it seems likely that the US carrier submitted passenger record data on Abdulmutallab to the TSA. But again, even if the TSA had singled out Abdulmutallab for enhanced screening or identified him as being on the no-fly list, how does it ensure that Dutch or Nigerian airport security take appropriate action? If a Dutch or Nigerian equivalent of the TSA have special requests with respect to a particular passenger departing from the US en route to the Netherlands or Nigeria, would the TSA automatically comply in reciprocal fashion? Note that according to an editorial in the New York Times, the TSA can still request a US-bound flight to return to its point of departure if there is a suspicious passenger on board, but for long distance flights, this option may become unfeasible if the request is not received until later stages of the flight.
Suggestions for changes already began to be voiced soon after the incident. Among the calls for improvements to security that have emerged in public discourse, the notion of making more use of body scanners, such as millimeter wave scanners, has been particularly prominent--notably former US Department of Homeland Security Secretary, Michael Chertoff, has been among those advocating this move (see here) (although it later came to light that Chertoff’s company, the Chertoff Group, has a manufacturer of such machines as a client). Some commentators, however, have argued that such full-body scanners would have failed to detect the explosive device in this case. The Telegraph has cited two former US officials from counter-terrorism agencies for having long argued that swabbing for explosive substances and other chemicals is “cheaper, easier and more effective” than full-body scanners. In that article, Larry Johnson, former deputy director of Counter Terrorism at the US State Department was quoted as saying “[s]wabbing everyone is not hard and it’s just about the only way, short of making passengers fly naked and without luggage, of being reasonably sure they aren’t carrying a bomb.” Although swabbing would entail making bodily contact with the swabs, for some--if not most--it may raise fewer privacy concerns than the full-body scanners. The Telegraph article suggests that the swab tests would not need to be taken from the same part of the body or baggage where explosives were located. That means that contact with sensitive areas of the body could be avoided.
In Part II, I’ll discuss databases and watch lists.

News: US SWIFT Access Granted
The Register quotes an EU official as saying that "The truth is that we in Europe don’t have the technical ability to interpret this stuff," and that this is the reason why "We rely on the Americans to process it and pass it on as intelligence." Many European intelligence agencies end up as beneficiaries in the arrangement as they are not permitted by their home countries to gather such information themselves. In the event, delegates were apparantly put under huge pressure from US representatives to pass the deal:
The pressure from the Americans was "massive," say diplomats in Brussels. U.S. Secretary of State Hillary Clinton apparently told her European counterparts that the fate of the West hung in the balance. And in the capital cities of Europe, American ambassadors stormed governments like door-to-door salespeople. As one EU foreign minister put it, "they pulled out all the moral and political stops."

News: SWIFT Update
The draft plan is significantly different from the resolution issued by the European Parliament on the issue. 'Terrorism' is left undefined, requirements for judicial oversight are nowhere to be seen and the restriction of access to the specific issue of 'terrorism financing' is loosened to "prevention, investigation, detection, or prosecution of terrorism or terrorist financing". Ralf Bendrath has a round up of all these issues and many more.
If a decision is not reached by November 30th, then, as the Lisbon Treaty kicks in on December the 1st, the European Parliament may have much more say in the process (and it is likely to take another 6 months). Germany and Austria are reported to be under pressure to drop their opposition.

Brigadier James Cowan, the new commander of British forces in Afghanistan, gave an interview to the Sunday Times in which he emphasised the importance of reassuring the local population of UK and US ability to provide security.
For the brigadier it is all about challenging the Taliban’s rule of fear: “What you have to do is create communities where people wish to be separate from the enemy because they have the confidence to be separate from them.”
Cowan’s staff have embarked on a huge exercise known as “human terrain mapping”. It involves not only delineating tribal boundaries, but also family networks, land ownership and all the possible grievances that can be exploited by the Taliban.

Inadequate Information Sharing Again Cited as Key Problem
Wednesday, October 28, 2009
How to Use Surveillance
Officials say FBI agents in Denver and New York had been tracking Zazi for some time — and experts analyzing the case say the way law enforcement gathered evidence against Zazi and possible co-conspirators may be a textbook case of how to conduct a terrorism investigation. The FBI used a blend of wiretaps and subpoenas, search warrants and local police, among other things, to build its case.
"I think what's striking about the Zazi case is not so much that new tools were being used, but that old tools were being used in a comprehensive fashion," says Sam Rascoff, who used to work terrorism cases for the New York Police Department's intelligence unit. "And that they were being stitched together in a thoughtful, strategic way, so that one tool naturally gave way to another."

EU Funding New Database to be used to Identify 'Abnormal Behaviour'
A number of interest groups have criticised the program:
Stephen Booth, an Open Europe analyst who has helped compile a dossier on the
European justice agenda, said these developments and projects such as Indect
sounded "Orwellian" and raised serious questions about individual liberty.
"This is all pretty scary stuff in my book. These projects would involve a huge invasion of privacy and citizens need to ask themselves whether the EU should be spending their taxes on them," he said. "The EU lacks sufficient checks and balances and there is no evidence that anyone has ever asked 'is this actually in the best interests of our citizens?'"[Liberty's Shami Chakrabarti commented] "Profiling whole populations instead of monitoring individual suspects is a sinister step in any society. "It's dangerous enough at national level, but on a Europe-wide scale the idea becomes positively
chilling."
