Austin Airport Tracks Cell Phones To Measure Security Line Wait
jfruh writes If you get into the TSA security line at Austin-Bergstrom International Airport, you'll see monitors telling you how long your wait will be — and if you have a phone with Wi-Fi enabled, you're helping the airport come up with that number. A system implemented by Cisco tracks the MAC addresses of phones searching for Wi-Fi networks and sees how long it takes those phones to traverse the line, giving a sense of how quickly things are moving. While this is useful information to have, the privacy implications are a bit unsettling.
Its not like they don't already know where you are when you are entering airport security.

A bit????
No, the privacy implications of this are downright creepy. Because the most unsettling thing is governments and corporations feel they have a right to this information.
And, it's not like you can opt out .. unless you simply don't fly.
And, then what does Cisco et al do with this information? Oh, right, sell it for profit.
Assholes.

Modern IOS versions randomize the MAC used for passive wifi scans. I'd imagine android is also doing the same.
Don't use the FREE effing wifi, if you don't like it. If you're not paying for the product, you are the product.
Turn off wi-fi. Done.
You can be tracked anywhere anytime you're using a communication radio. Deal with it.

I'm a huge privacy advocate... but how far are we going to go with this?
You're in a public place.
You're connecting to their network at various points.
They're using that info to figure out how long it takes for you to get through the line.
How is this any different than them using your check ins with your boarding pass?
"I just dumped the entire contents of my luggage in the middle of food court. I appreciate the offer to help me pick it up bu how dare you invade my privacy!"
How's THAT for an opt out?
I wonder how that works now Apple randomise the MAC address when looking for networks.
Don't the new iOS randomly pick a MAC address when scanning for available networks now? If you don't want to be tracked, don't connect to the airport Wifi.
Magic doesn't work in my presence. My power of disbelief is too strong.
"While this is useful information to have, the privacy implications are a bit unsettling"
We're talking the TSA... which means the DHS... and the NSA... so, imagine, if you will, how much NSAware is being installed in your phone to increase "your" safety.
If you've got a recent iPhone, it's already randomizing the MAC used for background scans:
Of course, that doesn't work if you are using the phone to read Twitter while waiting in line, because seriously, what else are you expected to do while shuffling along?
While this is useful information to have, the privacy implications are a bit unsettling.
As best I can tell from the description, this sounds similar to what Disney and other themeparks use to track their wait times for rides, except the amusement parks occasionally hand out little RFID "things" to guests at the ride entrance and ask the guest to give it to the operator.
As far as I'm aware, any time you're polling for WiFi networks you're broadcasting your MAC; this just seems like a fairly benign way to get information about a process without getting actual data on an individual.
Granted, you can somewhat reliably tie together a MAC addy's travel path if you have the ability to see all the places that MAC has been, but that was true even without this particular software.
So, yeah, what is the concern about this software in particular? It seems like the complaint is more with how the scanning for networks works.
So all those alerts warning you about broadcasting your IP were right all along!
Anxiety over being late (for work, or for a plane) is a common concern.. this will help alleviate it.
On the freeways where I live are large signs that show transit times to various points-- those are very accurate and very nice to have.If you're concerned about privacy and tracking, don't wear a device that can track you.
But if you're in an airport, you can assume your name and travel details will be reported to the government. Even if your local coffee shop wants to know how many you stop in for a latte, who cares? If you care, wear a tinfoil hat or unplug.
Certainly I don't want them to know I have a cell phone, that would be an invasion of my privacy while I wait in line for my NAKED BODY SCAN, right after I hand them my government-issued ID. There are privacy invasions happening there, but they aren't wifi related.
I don't see the need for a tinfoil hat here. If my phone is actively searching for a network, and the airport is using that information in a way that doesn't identify me, doesn't make my phone think it should be sending any other data, and generally makes my experience better, I don't see a problem. They're even letting me know that they do it.
I love my privacy, but this use seems perfectly sane. Yes, they could hire a Walmart greeter to sit on a stool and watch the line, periodically holding up a chalk board with an estimated wait time. But then we'd be decrying the creepy guy who keeps staring at us in line.
How about we actually see how some innovations play out before deciding that the airport is going to stalk us?
Take it to the limit, everybody to the limit, come on, everybody fhqwhgads.
Erm... how do you think the traffic apps work on your satnav?
They ask you to "anonymously" contribute statistics, they talk home over 3G to service centres, who spot traffic moving slowly (given speed and position is easy on a satnav), mark those roads with appropriate average speeds and then transmit that out to everyone with traffic services.
Sure, they use roadside monitors and other things as well but the "HD" traffic you might get from any large satnav provider uses exactly the same technology.
The question is not whether this is worrying data to collect, but exactly what portion of the collected data needs to be collected? If they are hashing the MAC's really quickly and then discarding the original MAC data, and only keeping MAC-hash and position data, then there's nothing to worry about.
Or, you know, you could write an inflammatory article about a technology that every satnav, every shopping mall, and even festival organisers have been using for years.
Seriously, all they would need to support this is to collect the MAC's on the individual access points. Note the time the MAC first appears, and the time it leaves any individual access point. There would be no need to record any other information. This sort of information It's already visible in every access point ever made, so whats the big deal? Now if they wanted to do some data mining by associating your phone's MAC to your boarding pass that would be more along the lines that people are complaining about. But really, the government already knows your flying from the time you purchased your ticket.
While it certainly saves the average traveler from having to guess the queue length and service rate for themselves so they can estimate the wait via Little's Law ( http://en.wikipedia.org/wiki/L... )
It is hard to see how it manages to not be confused by people standing around the entrance and then walking away rather than in, or separate those speeding through the Priority or Pre-Check lines from the regular lines.
It would seem a simple electric eye counter or just giving the guy who sorts you into lines a clicker might do just as good a job. So while I don't like hopping into the tin foil hat explanations too quickly it is hard not to suspect that maybe this is just a cover story for the fact that they are indeed using it for surveillance purposes.
But then they already know everything I am doing in the airport tracking my phone doesn't personally make me any more under their eye than I already am. Not that I like them gathering all this data and lying about what they keep, I'm just not sure this actually adds to the degree I have already had my privacy compromised by the government.

No, the privacy implications of this are downright creepy. Because the most unsettling thing is governments and corporations feel they have a right to this information.
If you are in an airport your are IN PUBLIC. Your privacy rights are significantly reduced when you are in public. You have no legal expectation of privacy in public. There is nothing remotely creepy about this. In fact I actually think this is a fairly clever use of the technology which allows people to easily opt out if desired.
And, it's not like you can opt out .. unless you simply don't fly.
There is an incredibly easy solution. Turn off your Wifi. Tada! Problem solved. If you have Wifi turned on then you are quite literally broadcasting your presence to anyone who cares to listen. It's like shouting at the top of your lungs in the airport and then telling everyone you have no way to opt out. YOU are the one broadcasting. It is YOUR choice. If you don't want people to listen then turn off your radio.
in Massachusetts (and probably other places) use Bluetooth phone tracking: http://www.mass.gov/governor/pressoffice/pressreleases/2014/0411-governor-patrick-announces-go-time-expansion.html
"The GO Time real time traffic system measures travel times between two points by anonymously tracking the Bluetooth enabled devices carried by motorists and their vehicles. The system complies with new federal legislation that requires real time traffic information to be provided to the public."
Okay, so turn your WiFi off before you walk into the airport. Super secret line monitoring DEFEATED! The TSA will never know where you are in line! You'll be like the Spanish Inquisition.
That's our life, the big wheel of shit. - The Fat Man, Blue Tango Salvage
Before you even get in to the security line you have already given the airport your email, phone number, full name, payment info, and given them permission to look up more information on you for security reasons. You are about to have your belongings and person scanned and possibly searched.
Your MAC address is something you are broadcasting nearly all day. Anyone with the right software can grab it out of the air. The reason they don't is because its nearly useless on its own.
My point is, you have already given the airport a plethora of private information, are you seriously going to freak out that they now collect something that you broadcast publicly almost 24/7? Whats more is the solution is as simple as turning off your WiFi!
Cattle have had tags that help their handlers track them for decades. You people asked for this so you could feel safe, and you kept asking for it, by voting for the same corporate shills who are delighted that you've been so distracted by "teh terrorists" (and gay marriage, and abortions) that you're not paying attention to what's been happening. No move along, before we get out the prod.
At PDX and other places a TSA guy gives you a little colored card with a number on it.
At the other end of the line a TSA guy takes it from you.
They time of the line is measured by the transit time of the card.
Is this more or less creepy?
I should use this sig to advertise my book ISBN-13 : 978-1501515132.
Me thinks the transit time is the plausible excuse here. They really want to know who is going where so that if they nab you for some 'offense' then they have a history of all the places you were at and security footage as well. 'Free' wifi that really isn't free if you consider the implications.
Of course, there are other instances where Governments have been rather crass about it:
A few years ago I was transiting at Singapore's Changi Airport. They had free WiFi, but subject to me giving them the MAC address of all my devices, the flight I had arrived on and they wanted to record my Passport number as well. The girl behind the counter said, with a big smile and fluttering eyes, everyone gives us those details and the WiFi is really good.
To get to that point, one has to:
1.) buy airplane tickets, most likely by credit card (I'm sure there's some way to use cash to pay for airplane tickets, but I don't know a single person who's done that in a decade). These tickets give a very good probability as to where you are going to be, when. ...so now they're using the MACs of cell phones to figure out how long people are going to be in the queue, and we're worried about "privacy concerns"? You're in the wrong place if you're worried about privacy in the security line at an airport.
2.) check in - in other words, directly inform the airline that you are at the airport.
3.) get onto a line whose exit involves partial undress (shoes, belts, jackets), placing your personal effects on a conveyor belt to be searched, and an X-Ray of your body.
What?! Whoever wrote this (timothy) doesn't understand technology.
Counting unique MAC addresses means nothing.
It is literally just the same as watching the airport cameras and counting the passengers as they move through security.
Do you really honestly think there are no cameras at airports? Are you that clueless?
Your ignorance is a bit unsettling. Put away the tin foil.

There are many things I would complain about, but an airport tracking information that you are publicly broadcasting is not one of them. You have 100% control over this. Pretty much the same thing as a server admin logging what IP addresses connect to his servers.
I don't see a great privacy implication here. WiFi is, again, a broadcast medium. If you've got WiFi turned on, you already know your phone is broadcasting to access points and that those access points know you're inside their range (and with the way modern beam-forming tech works, they have a good idea exactly where you are). If I were interested in privacy, I'd have WiFi turned off so I wasn't broadcasting my presence constantly.
If you are in an airport your are IN PUBLIC. Your privacy rights are significantly reduced when you are in public. You have no legal expectation of privacy in public. There is nothing remotely creepy about this. In fact I actually think this is a fairly clever use of the technology which allows people to easily opt out if desired.
Excuse me... When I'm in a public place, I can see everyone who can see me. It's symmetrical. The other passengers can see me, I can see them.
When someone spies on me electronically, that spy doesn't actually know whether I'm in public or not. Airports have lots of rooms where I could be that are not public. I can't see any justification why the fact that people can see me would mean that people can electronically spy on me.
If it comes to worse, I guess you could also put the tin foil hat on your cellphone and ground the hat. If that helps.
Worrying about this does seem a bit silly, given that it's trivially avoided by turning off WiFi and that by flying you're already participating in one of the most surveilled activities anywhere on the planet. I mean, this is a field where for some reason a lot of people just accept behaviour like strip searches (of the virtual and/or physical variety) and/or pat downs that would get the patter classified as a sex offender under normal conditions and/or pretty much arbitrary confiscation and examination of any property they're carrying with them, not to mention all the pre-travel details you have to provide for checking against who-knows-what databases.
However, the argument that when you're out in public you don't deserve any privacy needs to die. The law in most places may not have kept up with technology and its implications, but this argument is about as sensible as "if you have nothing to hide then you have nothing to fear".
Arguing that the historical privacy situation (if you're out in public, someone you walk past can see you) is like today's privacy situation (you're monitored by numerous cameras and sensors, using unknown automated recognition technologies, connected to unknown databases for future reference by unknown parties for unknown purposes) is a bit like arguing that the historical situation with carrying weapons (if the other guy has a sword in a dodgy area, letting you carry one yourself as well is reasonable) is like today's (where if you replace "sword" with "dirty bomb" then the results are on a rather different scale when someone abuses the system).
If you disagree, post your argument. (-1, Overrated) isn't your personal censorship tool for views you don't like.
In Copenhagen Airport, passengers have been tracked using Bluetooth for some years. The visible difference for the customers is a display that shows the security waiting time in minutes.
When someone spies on me electronically, that spy doesn't actually know whether I'm in public or not.
Explain how the airport does not know you are in public when you are standing in a security line and broadcasting a radio signal.
Airports have lots of rooms where I could be that are not public.
You are confusing seclusion with the legal concept of privacy. They are not the same thing. The airport is not private property owned by you. Generally speaking you have no objective expectation of privacy anywhere on the airport grounds so long as your Fourth Amendment rights to unreasonable search and seizure are not violated. It does not matter if you are alone in a room or standing in a public area.
I can't see any justification why the fact that people can see me would mean that people can electronically spy on me.
Nobody is spying on you. You are BROADCASTING your presence. Get a clue. If it bothers you then turn your radio off and it won't be a problem for you.
There are probably security cameras watching the line already. Use them to count the people. Software for this is available from several suppliers.
Cameras at intersections already do this, as part of traffic signal control. The best systems report things like "3 cars waiting at signal, then a big gap, then more approaching cars". The controller can then let three cars through, then turn the light for that intersection face red and let the other direction go.
However, the argument that when you're out in public you don't deserve any privacy needs to die. The law in most places may not have kept up with technology and its implications
It's not that you have no privacy in public but rather that your expectations of privacy are (and should be) rather limited. You might be noticed or you might not be but you should have no objective legal expectation that your actions will go unnoticed by anyone. As a general practical matter is is basically impossible to provide you with the sort of privacy you might expect in your home when out in public. There are legitimate public safety concerns as well as practical considerations. Are we supposed to avert our eyes because you walked by so that you can pretend you went unnoticed?

There is an incredibly easy solution. Turn off your Wifi. Tada! Problem solved.
These days, it isn't easy being an electronic ninja. Don't forget to turn off Cell, Bluetooth and NFC, the radios in your glasses, watch, fitness monitor, Tesla fob, headphones, tablet and gameboy, and disable the RFID tags in your wallet, luggage, shoes and clothing.
I don't know what it is, but slashdot editors just LOVE the hell out of cell phone tracking. I mean, there has probably been a story or two on the subject before now:

There's one wait-time display for each line to go through security, so before they get in line, travelers can join the one with the shortest wait. In effect, they do their own load balancing, which can minimize the wait time for everyone.
Based on the airports I typically use I had assumed that all of them used a single line with TSA agents directing people to a particular lane. Wouldn't that be a simpler solution?
I believe some traffic system also use the bluetooth address advertised by cell phones to calculate the traffic speed.
Has been done in Halifax, Nova Scotia, Canada for some time now.
Many airports, shopping malls, and other areas with large migrations of people in busy areas, do this. The systems are optimized for analyzing passenger and customer flows in order to allocate resources like number of staff at security, gates, etc. The more data points (check-in, security control, duty free, boarding gate), the richer the data. The overhead of doing anything else, like trying to match a device I'd. to an actual person, presents no value but only s bottleneck for providing teal-time analytics. Also, they can get that sort of data more efficiently through things like shopping loyalty schemes: Heathrow Airport practically mandates that every retail outlet scans your boarding pass (probably illegal under EU data protection law) and that they hand over ALL data collected from passengers. Airport security is my least worry
How dare they provide me useful info like how long my wait time is in minutes? I hate when people measure anything about me because I'm a privacy obsessed nutcase moron! Also I hate when strangers LOOK AT ME in the airport line, that also gives them information about how fast I'm moving and who I am, which I hate to have strangers know! That's why I always wear an invisibility cloak when I go through the airport security line. People bump into me a lot but it's a small price to pay to get .0001% of my privacy back because THIS part is the MOST IMPORTANT PART of my privacy really.
