Legoland Introduces Wi-Fi Tracking for Kids
mindless4210 writes "Lego announced today the successful deployment of a full-scale child-tracking system within Legoland Billund in Europe. The tracking system, deployed by Bluesoft, Inc and KidSpotter, allows park visitors keep track of their children using one of the world's largest Wi-Fi tracking networks. The children must wear a wrist band with a Wi-Fi tag on it, and if they become separated, parents simply send a text message from their mobile phone, and receive an automated response giving them the accurate location of their child."
The AeroScout Location System can locate the tags which I believe is in use with Lego's Kidspotter Wi-Fi tracking watch. The tag itself seems to be very small. Privacy concerns, anybody?
That'll come next :)
If you mod me down, I *will* introduce you to my sister!
No, I didn't RTFA.
I hope these things have some sort of security mechanism. You wouldn't want just anything being able to instantly locate your kids would you?
Given the history of these types of deployments it wouldn't surprise me if there were more than a few holes in any security (if any) they have.
A leash.
Oh great. We're now giving kids IP addresses so their parents can ping them. What it going on now?
Excuse me while I compile IPv6 on my systems. We need it now.

Wow, this sound like a great idea. The peace of mind for parents is great. Not to mention not having to use one of those horrible Child Leashes that make it look like you are taking your child for a walk.

...put this in my local mall! Nothing worse than seeing those terrified parents, or bawling kids looking for mommy.
[this is reasonably political - feel free to ignore]
Whereas this is bound to be a 'good thing' (the cry 'child in trouble' is just about the most instinct-driven response any adult has), the signature is somethinng to be wary of.
Consider that analysis of people-in-crowds is pretty easy these days. Consider that tracking (after positive analysis) is again reasonably simple (I was doing it 15 years ago - the key is to track in feature-space (region features: circularity, RGB, connectivity, 1st- and 2nd-order parameters) rather than just using image intensity. Using relations between features gives you context and thus more contextual information).
Consider that if you can track individuals within crowds, and given a covert surveillance system (eg: London, UK) you can track indivduals from locality to locality. You can start to (automatically) build circles-of-trust where individuals who meet regularly are automatically associated.
Consider that biometric information is now being put forward (eg: fingerprints, DNA samples, Iris scans, head ratios (eye:nose:chin parameters) and other observable information) and encoded within a compulsory identity card
Consider the amalgamation of this automatic identification, automatic relation of associates, and automatic recognition of individuals. Consider the implications. And yet a "Labour" government (the "People's" party!) is putting this forward in the UK.
I am fortunate. I am planning to emigrate this year to the US from the UK - previously I thought the UK (despite the lack of consitution) had a reality more responsive to the people and their ideals than the US. No more. I am one of the lucky ones that Joseph "Blunkett" Stalin will have no hold over. I feel deeply for my erstwhile compatriots. Freedom, after all, is a state of mind, and mind control is a tool of (this UK) government.

I've been trying to come up with a way to track my child slave labor, and this seems perfect.
Well, it's about time for kids to start wearing tinfoil hats.
The IT section color scheme sucks.
Johnny's location is: Wedged in the swing.
Its a nice step up from the Leash that some mothers seem to employ upon thier crying 5 year olds.
I wonder how they'll get a wifi tracker out of a kids stomach?
Thats where some of my sisters lego ended up.
But it kept breaking every time I moved.
The key difference between a Programmer and a Senior Programmer is that one of them is Mexican.
It shouldn't just give the location of the child. For a lot of people, that's totally useless. Most people couldn't tell you the difference between latitude/longitude and UTM coordinates. Instead, it should guide them to their child... let the parents page through instructions. Not only would this be more useful for them, they could get charged by the page, so our corporate overlords should be pleased as well (afterall, reuniting a parent and child isn't satisfying enough).
Secondly, what ever happened to Darwinism? The lost children should starve and/or form their own feral societies. Only the best would survive to re-enter society, hopefully as very productive, since they'll have lots of useful skills.
Lastly, where the hell are all the wolves? Aren't they supposed to take care of the lost children?
First post? I doubt it...
Down with Saudi Arabia!!!
"Asset Management" at its best :)

Show me on the doll where his noodly appendage touched you.
Better yet, you could port-scan their kid's IP and see if there are any "vulnerable security holes" :-)

We plop kids in front of TVs and now we let them run around amusement parks alone? Yes, I understand that this is probably intended for kids who get away from their parents, but you know some parent is going to sit somewhere with a laptop tracking their kid and not actually keeping an eye on them. I'm horrified.

Penguin Trivia #46: Animals who are not penguins can only wish they were. -- Chicago Reader 10/15/82
I'm normally opposed to this sort of thing, but in a place like a theme park this sounds great. Assuming that the tag could be hired from the theme park, you need only use it while you are there.
When you are in a place which the parent or the kid knows reasonably well, you can easily arrange a good meeting place if you get seperated, and the kid has a reasonable chance of finding it. OTOH, most people only go to a theme park occasionally: even if you do decide on a meeting place, you could easily get lost en route to it.
It could also help if the child is with the other (custodial) parent: the first parent can quickly check whether other parent is still queueing for a ride, or has gone onto designated meeting spot. Dh and I have tried using mobiles, but as dh's mobile is his work phone he is too likely to get work related calls for it to be particularly useful on his day off.
Does this mean we can ping our kids now?
Of course a dedicated enough geek pedophile could find a way of spoofing the signal to lead the parents on a wild goose chase I'm sure.
Or there's a good low tech alternative. Just take off the bracelet.
maybe they can put a camara on those thing, so the parrent can sit down in the pub, look at his phone, and nows his kid has a nice day.
Legoland earns more monney and the parrents don't have to walk trough those boring places...
Thus this is a nice way to get parents to consent to having their motions tracked as they move throughout Legoland, under the guise of helping "the children."
Imagine it... If you had a giant database of people's movements as they go through the park, you can more strategically position the food vending carts, move the rides and displays around in order to maximize the "candy aisle effect," etc.
...can you nmap it?
for kids!
I take it you haven't been in a place like that with 4 kids.
Gutless AC.
So instead of raising your head to look for your child you stare down at your mobile phone, haplessly unware that they just walked by. Come one people, this is just a waste of resources. ~ Nick
I hope his pants get caught and a bloodbath ensues.
What is with you today ?
I don't wish the kid harm, but his mother should suffer that horrific ordeal...
So she'll learn how to manage her child !
Sort of a harsh lesson.
Man, there's not a year goes by...
That I don't read about some escalator accident involving some bastard kid...
That could've been easily avoided had some parent-- I don't care which one--
But some parent conditioned him to fear and respect that escalator !
Though these WiFi Trackers do sound like a good idea, maybe if the parents kept a good eye on their children, the need for these trackers could be avoided.
amusement park for kids.
Which may be precisely the problem. "Peace of mind" causing parents to be inattentive, incautious, and careless. And when the systems goes down, as it inevitably will? Will there be civil liability, or will the parents have to sign a waiver of liability when they rent the wrist band for their child?
When the system goes down, will a child be lost, kidnapped, hurt, etc. that otherwise would not have been because his parents relied on the system instead of knowing that they, and only they were responsible for keeping track of their child?
Perhaps the analogy is a bad one, but this reminds me a bit of the problem national parks are having with people who *rely* on GPS and/or their cell phones to keep them out of trouble. No wilderness or outdoor skills, no ability to use a compass or read a map, and half of the time no jacket. But they figure as long as they have their cell phones, they'll be ok. And when they can't get reception, the battery goes dead, or they drop it.....

Why'd you have more kids than you can handle?
>"...giving them the accurate location of their child."
Actually, it will give them the location of the wristband.
The biggest problem I see is that this service is subject to a perfectly legal denial of service if anybody were to flood the place with any other WiFi signal...
That's the advantage that licensed frequencies have, they'd could be jammed, but then the jammer would be transmitting without a license and in trouble. Here the DOS wouldn't quite be covered by that.

/. all day on their employers dime, I'm horrified. People might surf kiddie porn, that's terrible. Whoever thought this internet thing was a good idea!?!
So lets drag out some end condition that some minute percentage of users might abuse the technology. Hell, why are you even using the internet itself if all you care about is to focus on the minority that might abuse technology? People might sit around on
The parent smells faintly trollish, but I will take it seriously for a moment.
"hey Ted"
"yeah Mark"
"I want to skip chemistry, can you take my locator with you to class?"
"sure no problem"
Unless you plan on implanting or clamping them on in some permanant fashion, this will not work. My opinion has always been that if a person can pass your class with out going to it, it is your fault not theirs
I'd gnaw off the wrist band and flush it down the toilet. The ensuing search in the sewer system by rescue teams should prove amusing...
"There is no spoon." - The Matrix
The "minorities" are not in the minority within the prison system. White people are bagged first kid. Anyone that has even spent a month in county knows this. I did it just for pointing a fake gun at a bitch on the freeway. I got convicted of a felony fool.
Of course it will happen, but I don't think there are many parent's who are going to forgo supervision simply because they know the can get the location of their child. Every parent knows that a child can get into plenty of trouble and danger in any location. The degree of which increases without supervision. So do we ditch the technology because people might abuse it ??? See my sig for your answer.

Bring on the tin-foil gloves!
I worked for Openwave, you know, the Software.com and Phone.com merger baby...
We worked with MMO2 in Britan, and they had a nicname for Fridays...SMS Fridays...
They would send SMS (Text) messages during the week, and the lost ones (which there were a lot of) would get delivered on Friday, when they system went through housecleaning.
So, send a text message looking for you kid at the park and MAYBE you will find out the location by Friday.
Have you checked my pants?
duh, an uncomfortable pokey lego themed (ever tried on one of those lego watches?) wrist band, yeah, the kids'll wanna wear that...
"Sic Semper Tyrannosaurus Rex."
I wonder how hard the wristbands would be to remove?
What's to stop kids from switching their wristbands?
I can't imagine being unable to find my kid, tracking him down, and finding some other kid instead.
Unless little Wally realises they are lost and has been reduced to tears, knowing where they are this instant will be useful for only a few seconds. I'm sure the mobile phone company is gleefully aware of this.
Why not fit the rugrats with something like those electric dog collars? If their squeals exceed X decibels or they move more than Y metres from their parent, they receive a little reminder from the collar... >:-)
My first thought was, "What, a CF card on each kid with a little microcontroller where you have to cha[r|n]ge the batteries every day?"
Then I looked at the website for the tags - 5 years worth of service, regular MAC address, only transmits occasionally, never receives.
Way geeky, I think. I'd like to know what kind of 802.11 packet they're transmitting!
Then I read the comments. Are all you guys privacy geeks, or what? What happened to all the "Cool technology! How'd they do that? etc" comments, consequences be darned (as in fixing holes in socks)
Ah well. So much for *real* geeks.

... I was more concerned with acurately tracking all of my lego pieces!

A friend and I came up with a similar idea, only we wanted to do it in, er, trailer parks.
Who would have guessed our idea could be extended across Europe.
Anyone know a good IP lawyer?
Sorry. Lost track of time. I'll have her home by 8:00 PM.
Considering that children don't usually wander far away from their parents,
What, you're saying that in an amusement park with a million distractions that it is not usual for a kid to get sidetracked? What planet do you go to amusment parks on?
Imagine it... If you had a giant database of people's movements as they go through the park, you can more strategically position the food vending carts, move the rides and displays around in order to maximize the "candy aisle effect," etc.
The sheer evilness of this is only balanced by the sheer genius. Let's see, lets plan our park by the meanderings of a stray 4 year old.
owh, yucky image. But, well, perhaps possible. I think I would point Nessus at the little buggers.
OK, having actually taken a child (my nephew) back in 1999 to Legoland (California) I can comment on why I think this might be a good thing.
Legoland has a number of "playground romper room" style attractions, which are very much kid-sized for kids. While they centralize the exits so you can watch who's coming and going from them, I was constantly pacing along the edge of it, trying to keep him in sight as he climbed around in the tunnels and bridges and such (some of these things were very large) and watching the exits as well...
While I doubt something like this would have kept me from trying to eagle eye him all the time while he played in there, it would have helped MY peace of mind for the 5 minute periods where I wasn't sure exactly where he was...
As another example, but going back farther to when I was the little kid. Many years ago, I was at Six Flags Magic Mountain (I think, its hazy, it could have been Knotts) when some of my family wanted to ride a roller coaster that I could not (probably would not, being the wimp that I was) go on. So my aunt and I waited at the exit for my sister and the rest of my family to get off the ride. I was impatient, so I ran to the exit ahead of my aunt, where I got swept by a crowd of people coming off and got confused (hey, I was maybe 5) and ended up following a group into a gift shop across the way. Of course, both my aunt who had tried to keep up with me and my parents when they got off the ride got fairly frantic in searching for me, but they found me fairly quickly (not before I had gotten scared and bawling of course. I told you I was a wimp.)... Having something like the finder wristband would have been great for them.
Inevitably, if you have a kid, they are going to get lost at a department store, park, amusement park, etc, even if you are the most attentive of parents, unless you're all about the smothering. While I don't think its a good idea to use this stuff as a substitute for paying attention to your kids (and contrary to the likely childless respondants here, I don't think that really would be how they're used most often), I do think the option of having it is a good thing.

What the fuck? How fucking stupid do you think we are??? Of course it gives the location of the wristband you dumbass.. and of course we know it could be taken off... but the chances of kids doing that is rather remote.
Jesus F. Christ, you "deep thinkers" here are really annoying because you think your deep, but your just dumb.
I was at a waterpark in Colorado a few years back that had a somewhat similar system, but cooler (imho). All the family members wore wristbands, parents and kids. Then you could go to a kiosk and scan your wristband, and it would tell you where every other member of the family was. That way you could let kids do their thing (like, wait in line 5 times in a row for the big slide), and the parents could do their thing, and anybody can find anybody else.
I believe also, the gates would sense the wristbands and the guards could stop any kid with a wristband that tried to leave. So you couldn't kidnap a kid with a wristband, and they couldn't wander off either.

Don't piss off The Angry Economist
Now if they could just integrate these with those electroshocking dog collars we'd have a complete solution. What use is there in being a obssesive-compulsive remote-control parent if I can't also punish my kids from a quarter mile.
zzzzzt. little shit.
I got lost at that exact park 18 years ago and my parents didn't find it amusing.
Keeping track of 3-4 children isn't as easy as it sounds. I didn't wander off by accident, I saw something shiny and got lost in the crowd really quick. I was around 4-5 years old and didn't speak danish at the time. Not easy for me to find my way to "lost and found". Luckily they managed to find me looking at some planet models. Geek in the making I guess.
Would it be possible to stream the data into a mobile phone game? I'm thinking something along the lines of Pacman or Donkey Kong where you chase your children.
The paedophiles could be the bad monsters in it. It would make the experience a bit more fun while you children were being abducted.
Si tacuisses philosophus mansisses. If you had kept quiet, you would have remained a philosopher.
Just think, some of these kids will taking such a likely to these things, that they'll eventually trade in the Legoland wristbands for house-arrest devices provided by their criminal system.

Mod parent up!
You talking about enclosed playgrounds inside the park made it clear how helpful this is. But it could even be better if we can turn it around:
SMS the park your kid is staying here (a particular play section) until SMSed off by you and you can sit at the border of the playground drinking your drink and waving whenever your kid shouts to tell you they achieved a new goal. If the kid gets distracted and wonders off you get an SMS ('subject has left through orange gate') and you can shout the kid back for walking away without permission before the kid is out of sight.

In my experiences with backcountry search and rescue, the major cause of disaster is delilberate, repeated, acts of stupidity. It is almost never just one thing that leads to grief. Reliance on a battery opperated electronic gadget just adds one more thing to a long list.

Obviously you learned your lesson. Jackass.
But wasn't one of the greatest things to do in a park was to wander around on your own, and play hide and go seek with your parents...
Maybe this could be used to discorage the child trafficing handoffs that occur at amusement parks.
Not to troll or anything, but what does it say when your child has been taken away from the complex? "Owned"?
there are bound to be hotspots outside the park, all a pedophile stalker has to do is crack into the system from the outside, or even from the inside using a PDA, and then get a ticket, or just find the kid if already inside, rip off the bracelette and take off with the kid.
looking at how pedophiles will go to get what they want, (remember the guy foubnd pantsless in his car searching for hotspots to download child porn?) this system could be abused, and hell, the pedophile could even work in the damn park, and could use the official system to keep tracks on lost kids himself.
Congratulations. You cluttered this world with your dumb brood. Were we supposed to care? Keep your smelly children close if you care so much about them.
Do we know if they will be using the tracking to evaluate park use? Compiling that information? I think we need to evaluate each new technology to see if the balance of our loss in privacy is outweighed by the benefit. In this case, I think as a parent of a child who may have wandered off before that I'd opt in, but
Years before I made my first tinfoil hat, someone showed me an article about a tracking device for pets.
It was placed under the skin and if the pet was ever lost it could be located. I was so naive, I never once thought anything like this would ever be used to find human beings.
So now here we are, just over a decade later and people think it's a good idea to track their kids using computers.
If your kids aren't big enough to understand the words "check in" and "meet up area" they shouldn't be away from you in the first place.
I'm certain that Lego will take security into strong consideration with this system. I am certain they will ensure that preditors of children will not be able to hijack the system and locate your kids as effectively as you can. Afterall, strong cryptographic authentication will be used and identifications will be universally unique, or some other such mechanisms will be in place... right?

After you rent the tag, the company knows:
I'm not saying all of the above happens, after all carnivals are know for honest people. It's not like they are run by Gypsies who steal children is it? Caveat emptor and consider what price you pay for the gadget and what it does for you.
All you are going to gain from the bands is a false sense of security. As others have pointed out, this only tells you where the wristband is and it is not a substitute for responsible parenting. The low tech way of doing this was to lead the lost child to a help desk and page the parents over an intercom. If the park uses the tags to not hire as many people to watch the park, actual security will decrease and you might want to keep a sharper lookout than ever.
Friends don't help friends install M$ junk.
for a kid to get freedom from his/her parents to go explore legoland by themselves. False or not, it gives the parents a sense of security that is likely to loosen their hold on the kid so they can really go have fun. I remember going to parks and lands like this but being unable to do what I really wanted to because of paranoid parents over my shoulder at every turn.
There are no real privacy issues here, except I suppose the old slippery slope argument that we are being slowly conditioned to accept radio tracking tags. As it stands though, this development seems pretty harmless.
Anyone catch the NPR piece on piracy today?
Seems to me like this, or a similar technology would be just the ticket to stop pirates from nabbing ships and their cargo.
I've been thinking that an rf transmitter tag with gps interface would work well.
I've built one based on a gps receiver, 2 meter ham radio, and the TinyTrack II Works great in my car, and with the ham radio APRS infrastructure... now how to convert to a ship in the ocean.
It would be great for cattle. Not bad for kids either, but I don't want to raise goats.
Oh wait, you want to treat you CHILD like livestock. I see. Damn the consequences, let me put my daughter in a commune, I mean daycare, with an ear tag and all so she does not get lost. They might even have a surveillance system so I can see her in her cage while I'm penned up in my cubicle. That's good training, it makes them pliable, errr, sociable.
Friends don't help friends install M$ junk.
Hmm the post says that the child must wear the band, which makes me think it is required. Well it is not, it's an optional rental. So this turns from a tinfoil hat article to some semi-interesting application of existing technology. yay.
Now parents don't need to even TRY and be vigilant over their kids. They can just cop the lax attitude that Hey, if my kid gets lost I can easily find him with this doo-dad.
Way to go technology. What we really need is less stupid parents. Anyone have an invention for that?
How about the parents get off the damn cell phone and spend time with your kids, if you are with your kids you don't need to know where they are.
This will not prevent child abductions at all. In fact, it may even make it more likely that the abduction is successful.
Consider that the device only works within the park -- and that many parents will consider this device as absolute protection. So when Joe Pedophile decides to kidnap a kid, he just has to make sure to get him out of range before anyone has a chance to query the device -- or simply cut off the wrist band. He also has more prey to choose from since more parents will be relying on the device to keep their kid safe.
False sense of security anyone?
... and I can see a high-tech ransom outfit using this data to know where one certain child would be for quicker in-and-out kidnapping. Or knowing when that child might have been separated from it's protecive older siblings.
Or how bout this: 5-year-old son of European royalty is playing at legoland, taken out by a sniper from a huge distance based on his location from an SMS query to their wristband system...
OK, I'm being dystopian, and hopefully the crypto on those wristbands is bulletproof, but if the potential is there it will be abused and to think otherwise is naive.
They will never stop until somebody makes the
Outside of Denver, there is a pretty big water park (that's actually run by the municipality) called "Water World". A few years back, Water World introduced a similar system. Users had a watch-style band (waterproof, of course) with a barcode and a radio transmitter. They could go to any one of many kiosks around the park (which each had a barcode reader and a plasma display) and scan their band. Each member of their party was displayed on the plasma screen.
Unfortunately, the system was torn out after it failed to generate any revenue.
Hmmm. I don't think the risk of being kidnapped is that big in Legoland, Denmark (being from Denmark I can tell you that the max. 5 child kidnappings we have here every year makes big headlines every time). However Legoland in Billund has a lot of very big playgrounds with a lot of exits, tunnels and stuff, so it is virtually impossible to keep an eye on your kid all the time - especially if you (as I do) have more than one. I for one will rent one of these when I go this summer - not to rely on it solely, but last time my son actually *did* slip by, and was quite hard to find again.
-._''_.-
I don't know about your kids, but the kids I know wouldn't stay put long enough to get a bead on them.
So you text something and by the time you get a response the kid is 50m from it -- and by the time you get there, you need to text again to figure out where they are.
I think it would be better if the band alerted park security and then injected a fast-acting, minimal tranquilizer into the child to keep him at the location reported by the device.

These products could certainly compete with the RFID tagging industry if cost and size were appropriate for the application. RFID tags have problems with near-field RF effects and antenna polarity. These devices would seem to be more effective since they are communicating over spread spectrum, then IP packets and not directly over narrow band carrier waves

I'm thinking about it, therefore I might be.
The one I got for my dog was subdermal, roughly between the shoulder blades. It couldn't be used to track the little guy, but if he ever went lost and showed up at a veterinarian or an animal shelter, they're supposed to scan each animal that comes in and verify or find ownership in the database. It would have never helped us get him back if someone took him and then never took him to a vet.

NB: YMMV. IANAL. Take the above with a grain of salt.
I think this system is quite good to purpose mentioned in the article but it can't be the only one to guarantee the children's safety.
On the other hand I would like to know more about this technology, for example, I would know how the wristband sender and the receiver work. There are RFID systems runs on without power own, in other words the system gets the power from reader unit, what's about these units used in the park? If some of these wristbands were very close or they were in fading zones, could be their signs incorrect?
Could somebody tell me where I can find more information about this kind of locate systems?

There are RFID systems runs on without power own, in other words the system gets the power from reader unit, what's about these units used in the park? If some of these wristbands were very close or they were in fading zones, could be their signs incorrect?
Could somebody tell me where I can find more information about this kind of locate systems?.
