Making a Child Locating System 1092

celtic_hackr writes "Well, I never thought I'd be an advocate for placing GPS devices on people. However, since it took less than three days for my local school district to misplace my daughter, I have decided that something needs to be done. By the school district's own admission it has a recurring problem of placing children on the wrong buses. Fortunately, my daughter was located, with no thanks to the local school district. Therefore, I would like input on a way to be able to keep track of my child. I know there are personal tracking devices out there. I have nothing against these systems. But I want more than this. My specification are: 1) a small unobtrusive device I can place on my daughter, 2) an application to pull up on any computer, a map with a dot indicating the real-time position of my child, 3) a handheld device with the equivalent information, 4) [optional] a secure web application/plug-in I can install on my own domain allowing me to track her from anyplace in the world, 5) a means of turning it all off, 6) a Linux based solution of the above. I believe all the pieces for making such a system are out there. Has anyone built anything like this? Is there an open source solution? How would I go about building my own? Has anyone hacked any of these personal trackers before, to serve their own purposes? How does a tinfoil hat wearer engineer such a device to make sure Big-Brother isn't watching too? Can these devices be locked down so only certain devices can pick up the GPS location of an individual locator? What other recommendations do you have?"

      This isn't mean to be a flame, because as a fellow parent (of toddlers, no less) I understand that it can be an extremely stressful and fear-inducing thing to lose track of your child. But I agree with the parent: get some perspective on things by waiting for a bit before subjecting your daughter to Big-Brother-like monitoring.

      Not only do I think you are overreacting, you are sending the wrong message to your school-age daughter. She doesn't need 24-7 tracking, she needs lessons in dealing with unexpected situations. Instead of jumping directly to an electronic device, teach her what to do if she gets lost... the same strategy that's been used successfully by parents for many, many years: find a "safe" adult (police officer, female adult with kids) and tell them that she's lost. If she's old enough to attend school, she's old enough to learn her phone number and address.

      Besides, if she's anything like most kids, anything you "attach" to her (short of a steel shackle) she is going to remove and leave behind or lose. :-)

      Again, I understand your reaction (on one level) but I think you're overreacting.

Also, to the posters who are bashing this person, and asking him/her to take the issue up with his/her school system, I think you're all overestimating the ability of many school employees as well as the efficiency with which requests get accommodated in many school systems. In my area, the public schools are completely overrun, mismanaged, and underfunded....badly. Now, I'm not advocating that the person asking for suggestions should try to exert some influence over the school system, but to act as though "fixing" the school's "problems" is easy doesn't really help.

          Besides, is it really that crazy of an idea for the kid to carry a cell phone (with or without GPS)? Nowhere in the post does it say how old the child is. I think some of the people jumping on this "overprotective parent" bandwagon are thinking this kid is some 12-13 year old kid. They might change their tune if (as the parent post points out) it's a 4 yr old girl/boy.

            My four year old boy got separated from us in the local supermarket. Due to some strange quirk of the mind (who can fathom the mind of a four year old boy?) he decided we must have left without him, rather than, say, we were in the next aisle (which we were). So he headed out of the main doors and wandered around for a bit looking for us. When he was picked up by the local Community Support Officers, despite being in a state of some distress, he was able to tell them his parents names and where he had been when we got separated, so that they could help him find us. Which they did.

            Children, even small, wooly-headed children, are much more capable than they are often given credit for. Teaching your child how to behave in an unexpected situation and crediting them with the intelligence and capability to look after themselves is the best way to ensure they make it through life safely. It's not the only way, but its far and away the most effective.

I walked to school every day, it was only a few blocks away, and I imagine if your kid went to one of the "city" schools, they all could have walked too.

        Recently in Austin, Texas, a man in a white van stopped abruptly on the side of a busy street 500 ft from where a school was letting out. He attempted to grab a 10 year old boy and throw him in the van. Luckily, the boy escaped and was able to run another 200 feet to a group of other children accompanied by an adult who called the cops. This was in broad daylight with other adults present (and no one managed to get a license plate number). If this man had gotten a better grip on the boy's back pack, he would have successfully kidnapped that boy. What police officer or safe adult can the child contact now? This is the worst case scenario and it happens more than people without children realize.

        The bus mix up was a simple miscommunication and an opportunity to learn, but that doesn't mean that worse can't happen. On the flip side, as a parent, you really don't want to completely shatter your child's innocence and put them in a constant state of fear. In my mind, an unobtrusive tracking device for young children who live in a large, impersonal urban environment isn't overreacting, it's responsible parenting. "Extremely stressful and fear-inducing" is an understatement when it comes to losing your child.

      " I would like input on a way to be able to keep track of my child."

      no one uses google now days....

      First, your child doesn't need GPS, she needs a cellphone. Why? Because even if you had this magical GPS tracking/locating system you want, there would still be some kind of data communication needed between the child and the laptop. That requires data usage or cellphone usage, so either way you're paying a monthly fee.

      Google child cellphone [google.com] and the very first result is Best cell phone for kids [msn.com]. In it, it says:
      "Migo is made to use Verizon's optional Chaperon service that lets parents track the phone in real time on their handset or PC. For an additional charge, parents can set up boundaries for where the child can go. If the phone leaves the designated area, a text message alert will be sent to the parent's phone. (Only certain adult handsets are capable of using this service.)"

      So you have the GPS tracking you wanted, plus your child has a cellphone so you can reach them if they're indoors and GPS isn't working so hot, AND you have the added feature you didn't even know you wanted: a text message the instant your child leaves a designated area. Not only that but it all works through your cellphone, so anytime you can't find your kid forget about going "Gee, I forgot to bring the GPS locator handheld with me". It's already setup on your cellphone.

      Oh and sure, all this will cost you a few bucks, but I'm sure it won't cost more than a custom handheld locater and a small unobtrusive device to attach to your daughter and and creating a secure website on your own.

      I have another cell phone idea. Rig up the pre-paid cell phone to shoot emergency flares when the number is dialed. The wiring should be similar to the IED designs the insurgency has been using in Iraq but you'll want to substitute the bomb bit for a emergency flare. I really can't stress enough how important that last part is. Now, affix the device on some sturdy head ware. You'll probably want to base this hat on a steel wok and just add a chin strap and remove any handles. Now all you need to do is mount the device on top of the inverted wok/hat and you're all set.

      If your kid goes missing just dial the number and even if you don't see the flares I'm pretty sure someone will contact you shortly after flaming rockets erupt from your child's hat. Wrong numbers might be an issue but it's a small price to pay for safety.

    However, since it took less than three days for my local school district to misplace my daughter, I have decided that something needs to be done. By the school district's own admission it is a recurring problem of placing children on the wrong buses. Fortunately, my daughter was located, with no thanks to the local school district.

    The problem isn't that you don't have a tracking device for your daughter. The problem is that your local school district isn't doing its job correctly and regularly putting kids on the wrong bus. Instead of posting on Slashdot for a technical solution, a far better solution would be a call to your local news organizations about how the school district is getting kids lost on their bus system and admits to doing that regularly. Raise a stink at school board meetings, PTA meetings, and so forth. Get other parents involved. You're talking about a school district's incompetence endangering not only your own child but all the children in the district.

    Pretend, for instance, that you get a perfect tracking device for your daughter. That sorta solves your problem, in that you can go and pick up your daughter from wherever she was left, but doesn't solve your neighbor's problem, and doesn't solve the problem of what happens to your daughter when she's standing around in a strange neighborhood.

    If this question came up a generation ago, before GPS trackers and similar devices were available, you would be looking for ways to better plan school events and to hold the schoolteachers and other school staff accountable for these kinds of mishaps. I think that's the right way to deal with this, though it's not the easy band-aid solution that installing a tracking device would be. In other words, the technological development of a wrong solution doesn't change what the right solution was all along.

    I just don't believe in this widespread approach of dealing only with the symptoms of problems. I might consider it (though wouldn't like it one bit) if it were a material object, but the fact that this is a human being should be all the more reason to address the actual problem. The irresponsibility of the school system and the fact that it has taken its obligations lightly is the actual core problem here. A tracking device only provides an incentive for letting them off the hook when they should have to answer for their failures. Yes, that would be much harder to arrange and would probably require political pressure from other like-minded parents, but it would be so much more worthwhile in the end.

      Well, I have and will continue to voice my concerns about the school and it's lack of good planning. I will be bringing it before the town council, and doing what I can to prevent it from happening. However, I don't have a great deal of confidence in the district anymore. I feel for the other parents too, but my prime concern is to keep my daughter safe. I have the ability to do this and thus don't mind the expense.

      I have to go pick up my daughter now.

    All you need to do is devise a complex computer with some decision making abilities and program it with information with destination coordinates in case it gets lost.

    Program it to recognize a local authority figure like a policeman or teacher and provide them with the destination information so that they can help it find home.

    I suspect the most effective hardware platform for such an application is some sort of fairly high-functioning biological organism.

    How would your device help your kid after she got on the wrong bus? Will you intercept it in your Batmobile? Worst case she spends an hour sitting on a bus till it gets back to the terminal and she gets the right one, or you pick her up. Doesn't warrant surgical implantation. School bus drivers do know how to handle kids who get the wrong bus.

    Your kid will hate you for this should you ever try to do it. And I wouldn't be surprised if you had to do a lot of explaining to child welfare agencies.

    You're like someone installing a firewall when an unpatched service allows arbitrary connections, instead of patching the service.

    Your school places your daughter on the wrong bus, that's the problem. Not that you can't track her. Solve the underlying problem instead. Either storm the principal's office and fire up a storm, get the PTA (if existant) to do something about the problem (since it's a "recurring problem" you're certainly not the only parent in that situation, get in touch with the other parents) and if everything fails, get another school to teach your kids (which is probably a sensible idea anyway, if they're not able to get your daughter in the right bus and didn't manage to teach her to choose the right one, it's likely they don't manage to teach her anything else either).

    You're looking for the solution for the wrong problem. The problem isn't that you can't find your daughter. The problem is that she isn't where she should be in the first place. Don't cure the symptom, cure the sickness!

    This happened to me when I was a kid. The school thought that I had signed up for Hockey, but hadn't. They sent me across town to hockey practice.
    Instead of freaking out, I got there and started playing hockey. Then I called my mom and told her to come and pick me up.
    Why? Because I didn't have psychotic over-reacting parents. I was smart enough to go "there is a problem here, I should fix it."
    And I did.

    How about you just teach your child what bus to get on. Or pick your child up from school. In 20 years are you going to want your child to think it is ok to track a person? Will your child be one of the ones that says "Well my parents tracked me as a child and I was fine, so lets let the government track us". The buses have numbers written on them just teach your child what number theirs. Once you advocate tracking people as a valid solution to a problem everyone is doing it.

    First off, write a letter explaining what has happened and send it to your school board, city council, and local newspaper-who-might-give-a-crap-about-this-kind-of-thing. Talk with your daughter's teachers, the school principal, and whoever else you need to to get some assurances that they're not going to do this again.

    Then, if you're still worried about your children being sent to the off-world colonies while you're not looking, talk with your daughter about what happened and how she can make sure she gets home on the right bus. If you really want a technological solution then buy her a mobile phone, maybe something like one of these beasties [fireflymobile.com] which can be locked down to only calling a handful of numbers (not a product endorsement, just giving an example), and make sure she knows how to call you at home if she has trouble again. Keep it charged and have her stash it in her jacket or backpack where she's unlikely to lose it. There's no need to weld it onto a metal cuff around her ankle, just let her use it to call you when she needs to.

    Hopefully you can both feel better about her security that way. You need to know that she is safe, and she needs to know that you trust her and that you are able to help her out if she has troubles. Strapping a prisoner restraint collar around her neck and monitoring her every move isn't going to do that.

    Have her repeatedly commit crimes (theft?) and local law will install an ankle bracelet. With this she should be either placed under house arrest andr hopefully be allowed to go to school. If she ever deviates from either location, law enforcement will contact you and let you know soon to be followed by them escorting her home safely.

    Just think of when your kid gets old enough to realize you're tracking her every move. Do you think that's going to go over well with her? What if you want to keep it on her to make sure she's not going to any "unacceptable" parties? There's a BIG consequence in doing something like this, in the parent/child relationship.

    I'd go w/everyone else and say "Get her a cell phone". There are plenty out there for kids that lock down so they can't call foreign countries and text 1000s of times to her friends. Simple. If she's in trouble or lost, she can call you. No need to go CIA on her.

    My daughter started carrying a cell phone in 6th grade for precisely this reason. It's paid off three times: Twice she got on the wrong school bus, and once we lost her in the press of the crowd during a parade. (That was really scary.)

    Before GPS became common, I had to rely on her description of where she was. Once (the parade incident) she had to go into a store and ask the attendant for the address. (I discourage her from asking strangers on the street, and she's afraid of the police, due to an incident a few years earlier, so we compromised on convenience store attendants. It wasn't a perfect solution.)

    Now, none of that is necessary. She carries a Blackberry Curve and I can check her location via Google Latitude on my own Blackberry. She knows that this is not because I don't trust her, but because I don't trust everyone else. Besides, she can also see my location, which forestalls "Daddy, when are you going to get here?"

    There are other tracking services, but Latitude was good enough for our purpose, and free.

    Hope this helps.

      I discourage her from asking strangers on the street

      Unrealistic threat assessment. The odds of a random person she approaches being evil are almost infinitely lower than the odds of someone whom approaches her being evil. Or, given the ratio of male to female predators, just tell her to ask a female, any female.

      she's afraid of the police

      Sadly, a realistic threat assessment for people of any age, not just kids.

      compromised on convenience store attendants. It wasn't a perfect solution

      Why? I think that's perfect. The odds of a random store clerk being evil are very low. In any transaction of evil, everyone knows she's on the surveillance camera, so thats kind of a downer for that plan. Most service clerks would love to help, hoping you'll say or write something nice to the boss or the newspapers. Its easy for you to find the store, gas stations are not exactly hidden from the street, and you've probably been there before so you know exactly where it is. Short of a donut store or a police station, I can't think of a more likely place to find a cop, hopefully a good one. Tell the kid, walk in the store, stand in front of the camera, and don't leave until you arrive. Away from the unfamiliar street means low odds of car accident. Most convenience stores are basically the same around the world, so no matter how lost she is, she'll be in semi-familiar surroundings, reducing panic and the bad decisions resulting in panic. Very hard to do better....

    As a parent in a city with 36 different schools and countless buses I know what you mean. But there is no reason to tag your little girl. All buses look alike, big yellow with numbers on the side. To make things easy and to avoid duplicate numbers from different bus providers they put a picture in the bus window on colored paper. So your kid might ride bus "Blue Hammer", So obviously the sign is on blue paper with a big picture of a hammer. If your kid manages to get on the wrong bus with that system, either they are not paying attention or they might need that "special" bus.

    You're upset that your daughter was lost, and everybody understands that. But you must consider what it means to have what you ask for become a trend, and to have the infrastructure built to make it easy to do.

    Perhaps when your child is 6 nobody will claim she has any rights, and you are free to lojack her. But then we will have to ask the question, when does she gain some dignity and rights, at what age does it become a bad idea for you to do this? At what age should it actually be illegal for you to do this? We have not had to ask that question until you do it.

    Location services all beg the question of what to do when one person is in power over another and can demand location data. You can over your young child, and more debatably over your older child. Can employers ask it of employees? On their breaks? Can husbands ask it of wives? Not demand it, you understand, but ask, as in, "Honey, what's wrong with me knowing where you are? Think how handy it would be. Don't you trust me? Don't you love me?"

    This is the world you will help build. But it gets worse. You see, there will be flaws in the system. Not just hackable security issues, but mistakes. After a custody battle, somebody will forget to turn off the non-custodial parent's access to the location data on the child. This will assist in many kidnappings. (As you may not know, the vast, vast, vast majority of kidnappings are by relatives. The random stranger that everybody is afraid of barely exists.) Perhaps not in your case, but in many people's in this world you are creating.

    A better idea? Teach your child, if lost, to approach a suitable adult, and hand them a card or show them her bracelet, which has your cell phone numbers on it. We tell children not to talk to strangers, but we forget to mention that means not to talk to strangers who approach *you*. It is perfectly fine to talk to strangers the child selects for help, more than fine, it's the right thing for her to do. Or sew the number in the lining of her coat, or shoes, or lunchbox or whatever. If you really think it's bad for her to approach strangers, teach her to identify police, teachers, people in uniform etc, but tell her that if she can't find one of those to approach any nicely dressed person.

    She'll be fine.

    I thank God I grew up before cell phones and this 24/7 parental obsession. My son has several friends in those last few years of parental control and it's driving me nutz. We can't even get together and watch a movie uninterrupted.

    One friend, his parents will call to tell him they're leaving his dinner in the fridge. Then call to tell him that the potatoes were over cooked, then call again to ask about next weeks soccer game. And it's literally every 10-20 minutes. If he doesn't answer, they call, call again and again... We'll stop the movie while he takes the call only to find out it's his mom wanting to tell him that next Saturday he has to go to Grandmas or something just as meaningless. If he complains "I'm in the middle of a movie!" She'll bark back "Too bad!, that's why we pay for unlimited cell usage, blah, blah, blah... so we can get a hold of you when we have too. Emphasis on "when we have too" is mine as it's apparently very subjective.

    It's absurd. And, yes, I'm a father.

    If I can't go a night not knowing where my son is, I didn't do my job as a parent. The world is not that scary nor dangerous. My son has a cell and knows how and when to dial 911 if he needs too. And I can certainly go a night not following a red dot on some tracking web page. I am sorry sir, but your fear is way over the top. Of course, as with anything else, that's just my opinion. Is is however a fear that you do share with a lot of other parents. Fear of what I wouldn't know as I don't share it.

    Even in this case of a younger female home late from elementary school because she got on the wrong bus. I still don't see the need for this level of panic or overreaction. But, that's just me. I suspect my son appreciates the levelheadedness of the home he grows up in. I expect his friends do as it's here they all congregate.
