back to article Mobiles help UK malls track shoppers' every move

Mobile phone tracking technology is being put to good use watching how punters migrate around a shopping centre, thanks to gear from Portsmouth-based Path Technologies. By installing receivers around a shopping centre the company can pick up communication between handsets and base stations, enabling them to track shoppers to …

    Cue.... (queue? que? Let's not start that again...)

    me turning my phone off and on repeatedly whilst waiting for the gf to decide which pair of shoes she actually wants. If they want to know where I'm going and what I'm doing, they can ask me.

    (And I'll say no, of course, but it's only polite for them to ask, rather than assuming that I want them to track me.)

    Any details which malls are involved in this?

    I don't see how this will work a Mall

    As once you are logged on to your network and no calls or SMSs are received, a message is only sent from the phone to the tower every 90 minutes or so, unless the signal is lost or the mobile requests to change cells. So the only way this could be implemented in a Mall is to put in some kind of mobile jammer at shop entrances that will block the signal temporarily and cause the phone to re-log on to the network.

    You can prove the phone doesn't send regular data by either leaving your next to a radio so you can hear the interference when the phone broadcasts, and if you are in a strong signal area this will not happen often.

    Or if you remove the battery from your phone (to simulate going out of coverage and so it does not send any shutdown messages), then phone it. There will be a 10-15 second delay before going to voicemail.

    If you turn it off via the off button and then phone the mobile you will be instantly sent to voicemail as when the phone shutdown it tells the network this is occurring.

    So if the network was expecting to receive data from the phone every few seconds, the delay to voicemail wouldn't occur if it wasn't shutdown gracefully.

    However this system would work for tracking across towns are when moving the phone will be often changing between cells.

    Slipper slope

    And no doubt some dick will demand that data be logged, for erm, anti terrorism purposes. That way they can map the existing log of the phone to the local log to locate the corresponding CCTV image which is also recorded.

    The EU has already accepted Blairs argument that it's perfectly OK to put people under surveillance and store that data away for a couple of years, JUST IN CASE they go onto to commit a crime, instead of actually have cause first, then warrant then surveillance....

    Once you do away with the old fashioned idea of privacy rights, this is only a tiny step away from that.

    Then other things become possible too, the German interior minister wants all transactions (email/internet/phone/atm everything) logged and continuously data mined for evidence of crimes. Having already accepted the principle of monitoring innocent people not under suspicion this too is only a small step away.

    And UK wants to record all transactions to outside UK, because non UK citizens don't vote presumably, it make it easier to justify. Having accepted that you can monitor innocent people without particular suspicion of crime, all things become possible. So they'd monitor the web to go arrest anyone looking at dirty prono sites no doubt, or reading up on 'lethal' cannbis plant sites.

    Why you could even demand the right to turn on their webcams and remotely record their own homes, hey they might go on to commit a crime.... think how much easier it is to arrest people if you can pull up their data at the flick on a switch.

    All things become possible when you remove the right of privacy. The ECJ should strike down that data retention directive, since it's that directive that accepted the principle of preemptive surveillance of innocent people, and it's from that, that all this creepy stuff is made possible.

    Bluetooth analysis is probably a lot more effective and legally less of a problem - if you leave Bluetooth on and discoverable (most people seem to do so) you are giving permission to be discovered.

    If this tracks people in and out of the shops, just think your average property company would be bound to latch on to the idea of:

    A. Raising your rent because of the number of people visiting you shop.

    B. Kicking you out because you aren't attracting enough business.

    C. Raising the rent of the coffee shop net door because there's more passing trade available.

    D. Raising the rent because of the average amount of time customers spend in the shop.

  18. Tom Wood


    Most shopping centres like this have CCTV which covers the entire mall. What's to stop them using this to track individuals' movements? (Though may be a rather manual time-consuming process until image processing techology gets to this level of sophistication).

    Is there really any difference (other than scale) if they track your movements by phone signal? In terms of privacy, assuming you've agreed to being filmed by CCTV (which you have by walking past the signs at the mall entrances), they can theoretically track you. The fact that they can do this by a different technology now (GSM signals) doesn't change the privacy issue.

    (If technology doesn't work, they could always send a spy to follow you at a safe distance...)

    Wireless Telegraphy Act ?

    I thought it was illegal to intercept transmissions that were not intended for you. This being under the Wireless Telegraphy Act of the 1950s.

    GSM / Timing Advance 101

    GSM uses a cyclical system whereby customers calls are all digitally sampled in turn. customer 1, then 2, then 3 etc... then back to customer 1 again. this all happens in a blink of an eye, so that customers can't detect the 'break' between each time their call is actually using a 'timeslot'.

    GSM then gets clever... imagine you are standing by the BTS (phone mast) with your mate, talking to them on the phone (as you do), but then they dash off to Maccy D's 1km away.

    You started off both covered by the same 'cell', and the BTS will use something called timing advance, whereby your mates signal is progressively broadcast fractions of a second sooner, to compensate far how far they are moving away from the BTS - this ensures that the above mentioned cyclical system remains intact, with customer 1 remaining as customer 1 within the cycle, and your mate say as customer 4... in a nutshell, timing advance tops your mates timeslot from running into customer 5's allocated timeslot.

    As timing advance technology is based on the speed of radio waves through air, it can be used to find how far you are from the BTS. the frequency of this distance checking signal is such that GSM Timing advance maps you into one of several 500m 'distance zones' - so for your mate 1km away, their signal would have been broadcast one to two timing advance periods earlier than it would have been if they were still stood by you.

    still awake?

    So - you then get B-A listing where your phone maps out ALL it's surrounding BTS's, and figures out how far away it is from each. it's clever brain translates this into a trigonometric map showing roughly where you are.

    HOWEVER the big no-no with this 'precision' shopping centre system is that the timeslot advance and B-A listing can only overlay several 500m zones over each other to build a probability map of which location you're actually in. You would need loads and loads of 'listening' equipment installed probably all the way out to 2km away from the shopping centre to get enough overlaid 500m zones to properly judge what individual phones are doing, This would require wayleaves and third party clauses with so many landlords etc for the install of 'black chopper kit' upon their rooftops that it would become unfeasible for a shopping centre to fund.

    so - my conclusion? it's not using GSM timing to figure out where you are

  29. DM

    @ Tom Wood

    There are clearly defined DPA issues with recording CCTV, hence the signs will have a legal declaration about what they are collecting data for, usually something along the lines of "for the detection and prevention of crime" . I've yet to see one that says "To collect and sell information about where you've been"

    That's the fundamental difference!

    Maybe it uses it's own proprietary system and just listens for the timing advance responses from individual phones without using the GSM carrier as a reference..... but itself uses much faster clocking to count how many cycles between each incoming signal. This would achieve a much more granular detection system (100 times faster detection cycle/frequency than the native GSM network would give a 5m distance zone.....)

    So just a few of these would be needed in the shopping centre to track you anonymously, and it's completely non invasive, being a listening only network of little black boxes

    ok - so it's not GSM but exploits the fact that radio's are uniquley identifiable radio transmitters....

    hang on - stick a bit of carrier wave amplitude modulation caused from power surges when you're actually talking down the microphone (inducing a current in the phone, therefore stronger radio output, intentional or not) and you have a way of bugging mobile phones whilst on your premises!

    could just use simple trigonometry

    It does not have to be rocket science, just clever use of trigonometry. While three active directional and active receivers would do for tracking if for pragmatic reasons any company implementing this might choose say eight receivers to cover a volume (mall) between them. It is not difficult to trace any sending technology with extreme precision. Also it would be possible to have software which did not get very confused by resets of the mobile phones. This could be sorted by error correction and probability algoritms. Yes it would not be 100% correct all the time, but it would certainly be working most of the time - how many mobile phones do you reset at the same time within any small volume of space? So if you only reset one phone - how likely do you think that the software would be able to correctly assume that 'the new' which all of a sudden appeared in the middle of the mall is the same as the one which just 'disappeared'? In fact you could even ignore the identifier in the signal completely and develop a reasonably reliable survaillance system by just having a signal to listen to.

    The Wireless Telegraphy Act would cover this the TMSI would be classed as information that is not intended for the reception of the shopping centre! If the TMSI is encapsulated with other data, but recieved and separated, surely that is an offence just in the recieving part of it!

    The TMSI's purpose is for handsets to be identified on the network, therefore the only people who would have a use for this is the handset and the phone network. Clearly not the third party (Shopping Centre) !

    It doesn't work.....

    ..... reliably unless you have Bluetooth on!

    After reading the patent application


    The equipment has a a plurality of receivers capable of receiving all mobile transmissions including but not limited to GSM, CDMA, Bluetooth and WiFi.

    The system searches for a unique identifier in the monitored transmission, this unique identifier in GSM could be the mobile device's IMSI, TIMSI or IMEI. For Bluetooth or WiFi, the unique identifier could be the mobile device's MAC address


    So unless you have an active call on your mobile the only GSM transmissions that an idle phone will make is a periodic update which is around every 2-3 hours or more on most networks, or a paging boundary change which is unlikely (but not impossible) within a shopping centre.

    By not emphasising that bluetooth is the main means of tracking you are left in a quandary about whether you should switch your mobile off and be uncontactable , but you would certainly switch off bluetooth if that was the main method of a passive system tracking you against your wishes.

    They will get very limited information from you walking round with a mobile with Bluetooth switched off . I would estimate most of the data from GSM transmissions alone would be worthless compared to a beaconing Bluetooth mobile.

    - It sounds like it's in breach of the Wireless Telegraphy act; can anyone suggest a loophole that they might be using?

    - These people say the data is anonymous, but the Data Protection act's definition of personal data includes "data which relate to a living individual who can be identified from those data and other information which is in the possession of, or is likely to come into the possession, of the data controller"; since this data could be correlated by the shopping centre's management with their CCTV records, or by a store with their card payment records, I think it's clear that it is personal data.

    - It probably doesn't work properly anyway since the phone to base-station messages when inactive are only every hour or so.

    Already done.

    In Reading, we trialed, and still have, the 5 point facial recognition software. All the cameras are linked to a central control room, including the ones in the Oracle shopping center and other shops. Many of these are also linked to the tills, so everywhere you go, and everything you buy is stored with an "anonymous" code generated from the ratios and angles of the five points. This is the reason why some shopping centers banned hoods and caps a while back, as they interfered with the system.

    If the police want to investigate you, all they have to do is feed the system a photo of you, which can then be matched with the stored logs, and they can bring up all this information. Many of the traffic cameras also now use ANPR, so they know what car you drive to the shops, where you go and what you buy.

    They're soon going to be trialing (or possibly have already started) extra sofware that automatically alerts security if you are "acting suspiciously". (quite likely considering how suspicious the police are)

    So act a bit shifty in Reading, and be assured that some plod is browsing over your every move in the town for god knows how long. Since the data is "anonymous" I'm not even sure they have to delete the data after a certain amount of time.

    Unsuprisingly this phone thingy doesn't really worry me. The technology behind it seems flaky at best, and you can turn your phone off, unlike your face.

    "What happens when people stop buying? I would love to find out."

    This has been tried by various groups in America and has spread around the world. They stopped buying anything new except essentials for a year, some are making it a way of life. The only detail I can remember is that other members of their communities branded them communists and un-american, apparently shopping is a form of patriotism.

    Search for "the compact" or freegans, the latter seems to be a PC word for tramp, or try this.

    Re. "Maybe..."

    "hang on - stick a bit of carrier wave amplitude modulation caused from power surges when you're actually talking down the microphone (inducing a current in the phone, therefore stronger radio output, intentional or not) and you have a way of bugging mobile phones whilst on your premises!"

    Have you got any idea how weak the signal from a microphone is compared to almost any other signal inside a mobile phone?

    The impact these percentages of a microWatt of power has on transmission strength is several orders of magnitude below the noise floor generated by all the other components (like the display).

    If yelling into the phone could give a measurable impact on transmission power, you should consider patenting a sound-driven phone charger.

    Further ramifications

    If the mobile phone provider keeps a record of what temporary ID was assigned to which phone/subscriber at any given time, then it's a trivial matter for the data to be un-anonymised.

    So *there*'s a nice little earner for the operators of this tracking software: "Hey, Orange, want to buy some data on your customers?"

    We can see you, hear you, read your eMail, track you - we OWN you...

    'Most of the GSM connection is encrypted, so there's little chance of an individual customer being identified.'

    Of course - but just think how much more valuable the information would be if it were tied to your real ID?

    Still, no one would be working on that - would they?

    This really has gone far enough. Phorm, the Government's proposed database of ALL telecoms data, and now being tracked via our mobile phones!

    What we need is legislation that makes collecting information of any sort about ANYONE, by ANYONE, without a court order granted by a court sitting in open session, without the individuals consent a serious criminal offence.

    The alternative is: Wait for the current incompetent Stalinist incumbent to be evicted from Downing street, give the replacement a couple of years - on the off chance he's remotely capable - then move out to the country with the most effective privacy laws you can find and would be happier living in.

    @ Respondents to "I don't understand".

    Thanks for your replies, but I still don't get it. How can you have concerns over your privacy when you are in a public place?

    Yes this technology makes it a lot easier to track you, but it's nothing the shopping centre couldn't have done anyway had they wanted to.

    We apologise for the late arrival of this apocalyptic scenario, which was due to a signal failure at Charing Cross and smarm on the line at Downing Street.

    Nothing has been mention in the local Portsmouth news about this scheme, or as far as I am aware to the local retailers in Gunwharf. Saying that, it might just be where I used to work the manager had his head in the sand/up his ar$e and didn't understand what it was about so didn't pass the info on...

  79. nutellajunkie


    I dont mind anyway.. But it would be nice to be able to see this tracking data and be able to access it from home. Just for the amusement of watching your own bread crumb trail.

    Still, the old battery may not like the constant /ping.

    Has anyone tried using their mobile in a shop in Gunwharf at Portsmouth? Good luck, as soon as you get inside a building the signal will drop or completely disappear.

    I worked there for two years and trying to send texts on the shop floor/back areas was a nightmare. So does this mean you will be reconnecting to the masts regularly, therefore getting a new TMSI, therefore meaning most of the info they collect will be rubbish?

    Depends if they're backless, strappy or Doc Martens.

    I think you'll be safe 'cos only ladies look at red shoes (unless you have a shoe fetish or something).

    Anonymous coward wrote "What's not very clear in that picture are the four stub antennas on top, maybe one for each GSM network?"

    I suspect that the 4 aerials are so that the receivers can determine the direction of the signal by using the phase difference between the aerials - a common DF method for VHF & above. Direction info from 3 or more receivers can then triangulate the position of the transmitter with pretty good precision, as per the patent brief posted earlier.

    What I do not understand is how they get all the phones to transmit often enough to track movements effectively. Bluetooth cannot be the answer because it does not have the range (power) to be received over an area as large as a shopping centre.

    If phones are being made to transmit frequently enough to track shop visits, then as others have pointed out, it will very seriously run down the phone's battery.

    @Richard Bragg

    Oh kindred soul! I too have a mobile, "only for emergencies" (ie. lift home when the trains are up the spout!) and on-call work, all other times it's off, usually due a flat battery much to the annoyance of my better half!

    I was thinking of putting an organisation together of people who still manage to live without mobiles, but I can't quite figure out how we would be able to all meet in one place yet?!!

    I have no mobile at all. Why don't we meet at gunwharf?
