Graduate Students Analyze, Crack, and Remove Under-Desk Surveillance Devices (vice.com) 86

"Graduate students at Northeastern University were able to organize and beat back an attempt at introducing invasive surveillance devices that were quietly placed under desks at their school," reports Motherboard: Early in October, Senior Vice Provost David Luzzi installed motion sensors under all the desks at the school's Interdisciplinary Science & Engineering Complex (ISEC), a facility used by graduate students and home to the "Cybersecurity and Privacy Institute" which studies surveillance. These sensors were installed at night — without student knowledge or consent — and when pressed for an explanation, students were told this was part of a study on "desk usage," according to a blog post by Max von Hippel, a Privacy Institute PhD candidate who wrote about the situation for the Tech Workers Coalition's newsletter....

Students began to raise concerns about the sensors, and an email was sent out by Luzzi attempting to address issues raised by students.... Luzzi wrote, the university had deployed "a Spaceti occupancy monitoring system" that would use heat sensors at groin level to "aggregate data by subzones to generate when a desk is occupied or not." Luzzi added that the data would be anonymized, aggregated to look at "themes" and not individual time at assigned desks, not be used in evaluations, and not shared with any supervisors of the students. Following that email, an impromptu listening session was held in the ISEC. At this first listening session, Luzzi asked that grad student attendees "trust the university since you trust them to give you a degree...."

After that, the students at the Privacy Institute, which specialize in studying surveillance and reversing its harm, started removing the sensors, hacking into them, and working on an open source guide so other students could do the same. Luzzi had claimed the devices were secure and the data encrypted, but Privacy Institute students learned they were relatively insecure and unencrypted.... After hacking the devices, students wrote an open letter to Luzzi and university president Joseph E. Aoun asking for the sensors to be removed because they were intimidating, part of a poorly conceived study, and deployed without IRB approval even though human subjects were at the center of the so-called study.

von Hippel notes that many members of the computer science department were also in a union, and thus networked together for a quick mass response. Motherboard writes that the controversy ultimately culminated with another listening session in which Luzzi "struggles to quell concerns that the study is invasive, poorly planned, costly, and likely unethical."

"Afterwards, von Hippel took to Twitter and shares what becomes a semi-viral thread documenting the entire timeline of events from the secret installation of the sensors to the listening session occurring that day. Hours later, the sensors are removed..."

      wads of chewing gum would be one way to cripple this system

    • . . . as long as it's supposedly "anonymized" (at first, anyway), what's the big deal?
      • I haven't read the study, but this type of thing can be done pretty easily with an ESP8266, and it is hard to believe they didn't do BLE beacons at the same time with the chip. It is also hard to believe that the sensors themselves anonymized data; it was likely anonymized (if at all) at the database level.

      • Allow me to pose you some questions. In the olden days, before social media, a small measure of personal privacy existed. The monetization of data hadn't been invented. Now, like this, someone has imagined a new way to gather data.. So..

        Is it wrong for a person to want privacy?

        Is it right, that just because I didn't explicitly say No, that the school has rights to gather any behavioral or biometric data they want?

        For women : does it matter that unknown actors know your menstrual cycle?

        Where are those lines
      • Groin?

        Is it possible that what they are actually looking for are illicit phones or other devices slipped in during exams?

      • If you use terms like supposedly and place anonymized between quotes, we don't have to talk about de-anonymization anymore. Which is trivial in a group so small and consistent as a school. Anonymization is an excuse, not a cure, for privacy invasion.

    • spying on students who give the university money

      Most graduate students don't give money to the university. They receive money from the university. They are employees, not customers.

        spying on students who give the university money

        Most graduate students don't give money to the university. They receive money from the university. They are employees, not customers.

        This is incorrect. Looking at federal loans [ed.gov], the average amount of debt for undergraduate and graduate loans is almost the same. Some graduate students at some schools get free tuition and some don't.

        then lying about it

        The proffered explanation, while stupid and unethical, is most likely true.

        The proffered explanation and the students' claims are not necessarily exclusive. Just because there was some thought given to an academic, anonymized study does not preclude misused of the data.

          Generally they pay less than minimum wage, dump loads of work on you, and then stipulate in your contract that you're not allowed to have another job.

        • by ceoyoyo ( 59147 )

          My grad school required that students be paid $6 an hour, assuming 40 hours a week 50 weeks a year (lol). Before taxes. And you were prohibited from having another job.

          The thing is, the OP is correct, you are an employee, but you're also a student, so they just call you "trainee" and consider you whichever is most convenient at the moment.

          • A gross negative and a net negative still mean that the University is giving money to the grad student instead of taking money from them?

            Alrighty then.

              You're going to have to be a little less cryptic I'm afraid. I know it ruins the clever biting nature of the quip.

              I definitely got money from my grad school, yes, net over what they took back in tuition. Just very, very little.

      • Most graduate students don't give money to the university. They receive money from the university. They are employees, not customers.

        I think this applies more to post-graduate (PhD) students than graduate (Masters) students.

          I think this applies more to post-graduate (PhD) students than graduate (Masters) students.

          It really depends more on the field. For example, law school, medical school, and business school almost always make the students pay. English and the hard sciences usually pay the students. It's just a matter of whether you're valuable to them as a teaching/research assistant. They save tons of money by paying graduate students a small "stipend" to do a job that requires a professional. These positions pay less than adjunct professor positions, which also pay less than minimum wage.

        • by ceoyoyo ( 59147 )

          The "graduate" that you're post of is graduation from an undergraduate degree. Both masters and PhD students are "graduate students." They're usually treated fairly similarly. In some places there aren't even separate programs, a Masters is just what you get if you don't fulfill the requirements for a PhD.

      It seems he was spying on the use of the tables, not the actual students.
      The sensor only sees heat but does not form an image.
      I don't really see how this is invading privacy or such things.

    • Oversight of many university executive positions is mostly non-existent. Unless they've done something outright illegal, you need to get, pretty much, the entire board of governors to agree to oust the president, which is usually almost impossible. There have been multiple instances of university presidents completely abusing their power, and, as they didn't violate their contract, absolutely nothing happened to them.

    At work many got into trouble because the used the work email, on company servers, to do personal stuff. Employees were using devices that were owned by the company, e-mail that was paid by the company, and got made because they did not have privacy of a personal account.

    Beyond the surveillance issues, he lied to the students, hasn't really explained why this measure was necessary (as opposed to less intrusive measures to monitor whether desks are in use), and when sunlight is shined on this, he folds which implies something skizzy.

    And unfortunately, as surveillance has become more pervasive, discussions don't work, laws regulating don't work, nor pointing the cameras back.

    Maybe people losing their jobs when they pull stunts like this might.

    • I'll play devil's advocate and propose that this is something a little bigger than it appears at first glance. This being done at an institution that is looking at privacy is too much of a coincidence and a slap in the face on top of that. Is this a study that's actually designed to look at how the students react, subvert, or otherwise respond? It's possible that it could be a bit sloppy, a modern Stanford prison experiment.

    looks like a pretty basic PIR sensor (I cant see a teardown or any actual details on why its not encrypted )

    assigning a desk and then counting if you used it... hmmm as they say the student had keycards so this was just a fluff "research" to back up if the companies devices worked or not...

    turning the students into lab rats is pretty common but normally there is a vote/opt in so what they did here is not follow process and since the students are paying for their education (this is america) its the wrong thing to be doing.

    anyone actually have teardown photo's and details on the firmware screw up ?

    These are actually pretty neat.

    Pointless in this context, and they create more radio noise (which seems to have hurt one real experiment), but nice battery life.

    One has to wonder what the real purpose was? Trying to justify eliminating space/moving to a hoteling model?

    This "study" WAS terrible, unethical, and a waste of money. In fact I'm doubtful there ever was a study at all and imho this was most likely either some kind of quid pro quo for the spyware company or an attempt at further normalizing orwellian surveillance state behavior.

Luzzi had claimed the devices were secure and the data encrypted, but Privacy Institute students learned they were relatively insecure and unencrypted....

    For goodness sake, these devices don't have cameras or microphones, it's a "person detector", it tracks when there is or is not a body at the desk. Why in the world would this need to be "encrypted"? What elaborate "security" is needed?

    If the devices are on a network, they have a unique ID (MAC address, for example), but beyond that, they are tracking a Binary phenomenon, either there is or is not a body at the desk. If you don't match the unique ID of each sensor to a particular desk, there's plenty of sec

      Please, explain the harm of an automated sensor that does exactly the same thing any person walking through the room would observe - detect if someone is at a particular desk.

      According to TFA, desks are assigned to individuals. So this is 24/7 monitoring if you at your workstation. When did you arrive? How many time did you step away from your desk? For how long?

      Sure, someone walking by could do a headcount, but they probably aren't writing it down, and certainly aren't there 24/7.

      "Please, explain the harm of an automated sensor that does exactly the same thing any person walking through the room would observe"

      You have the answer, right in your question.

      The big problem with automated monitoring, is *scope*. It's one thing to live across from a neighbour, it's another to know what people are doing 5000km away, and another thing further to write it down, track, it, and correlate it with other movements.

      This is no way, even closely, the same as someone seeing you sitting there.

      - When "Bob" sees you sitting at the desk, does he write it down, put it in a database, and that data is kept for decades?

      - Is that data now

    • by RazorSharp ( 1418697 ) on Sunday December 04, 2022 @09:16AM (#63101302)

      The problem is normalizing tracking. You can look at most forms of data collection and argue that it, by itself, is innocuous. But this stuff doesn't happen in a vacuum. As another poster pointed out, they have assigned seating and so that links the sensors to individual students.

      We're normalizing having all our movements tracked—both physically and digitally—and I don't think that's a good thing.

    These have been used for years at call centers and other offices to basically see if reps are stepping away too frequently for bathroom breaks. Weird it seems every single commenter thus far hasn't heard of them. They typically use PIR. Weird to call that "heat detectors", but I guess technically true? Unless a PIR is hacked in some extraordinary way (replacing the sensor?) you're not going to get a heat value out of it.

    Ugh. Just uuuggghhhhh. What university administrator thought this was a good idea? These people are supposed to understand grad students, but this shows serious disconnection from their job. Just a bad idea in soooo many ways.

    Grad students are a seriously weird, stressed-out bunch. They let nothing get in the way of their work. They will steal equipment, jimmy a door, filch supplies, and break any and all safety rules to keep their work going. They’re certainly not above putting the tip of a pen straight through a sensor that’s literally pointed at their genitals for no good reason. Omg hahaha I cant stop laughing.

    Another angle to this - grad students on GRA support are legally paid for 20 hours, but it’s universally accepted that 40-50 hours per week is required to make decent progress on a thesis project. Does the university really want to be taking hard data that proves their entire grad student structure is built on a foundation of flagrant violation of basically ALL the labor laws?

    So funny.

    You can not do these kind of studies in a university without IRB approval. I certainly hope for the researcher that they did get IRB approval, otherwise that is one of the few cases where you could get fired.

  • True grad school story: Faculty wanted graduate students to punch in every time they worked because they suspected students were goofing off. Students enthusiastically supported the proposal, because it would document how poorly they were actually paid per hour (since everybody worked a lot more than 40 hours a week). Faculty realized what was about to happen. Proposal died w/o as much as a peep - and never came up again.
