RE: Someone stole my Neo Freerunner... :(
-Message d'origine- Very interesting. Openstreetmap already has a webserver that looks up locations by URL, such as: http://openstreetmap.org/?lat=63.41283lon=10.4888zoom=15lay ers=B000FTF Would such an URL work on a MMS-capable phone? This URL is javascript, but a few simple calculations can yield a link directly to a tile png file instead. Helge Hafting The URL won't work as an sms, because it has to be wap, not http, and you can only query your provider mms server, not just any URL. But the same principle could be applied as with the script which sends back the position of your FR upon receiving a given SMS. You'll 'only' have to browse the url and extract the image part. It would be faster to implement than a 'real' mms browser i guess.. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Re: Someone stole my Neo Freerunner... :(
Sorry for you, hope you will be over it soon and up and running with a new one. For any ideas regarding this issue, please document them in the Wiki: http://wiki.openmoko.org/wiki/Anti-Theft_Mode I think that someone who has stolen a FR will not be willing to use it as a phone and perhaps not even has the knowledge to make something useful with it. Therefor I would insert a small offer in the case of the FR saying Call me at phone X and I will pay you Y on device return. I do this as well with my FreeBSD based laptops. matthias I'd prefer to lose my FR rather than paying my robbers for something that is mine, and thus giving them an incentive to keep robbing. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

At least the thief can't use it that way, but he'll just throw it away. If you want it back, consider software that does this: 1. Sends a sms with gps location now and then. But not so often as to use up the battery quickly. 2. Replace the usual ringtone with Help, this phone is stolen! 3. Replace the window manager with a single window that reads: - This phone belong to: name address any other contact info, phone, email,... Please return it for a $nn refund. - There should be no user interface here, no buttons to press and no way out. (If you get it back - reflash or log in with ssh to get it out of stolen mode. You should have a nice long root password.) Some thieves might go for the refund, when they find that the phone cannot be used at all. Others might throw it away. Someone else might find it and go for the refund, or you might be able to find it at the reported gps location. Still, if you want to brick the phone badly - overwrite the gsm modem firmware. No more calls! Then overwrite both nand flash and nor flash - nor more boot. Or maybe the boot message could show the stolen message above, and shut down again after a minute to conserve battery. After this, a debug board will be necessary. Helge Hafting ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Locked WinMo devices optionally display a message (e.g. for contact/reward details), in addition to the keypad for unlocking the phone, when switched on or woken up. This would allow return of the phone whether it was stolen or simply lost. Bricking the phone won't get it back, but having the above, plus having the phone report its location regularly, would seem to maximise chances of recovery. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Add a location pointer, and send it as a MMS image? Most phones can display an image, and you won't need to look up the coordinates manually anywhere. The most useful tile would be one that doesn't have the position too close to the edge, and maximally zoomed in. (Depends on what tiles there are.)

Just one little consideration: how best to turn off stolen-mode when I get it back? Sending an SMS won't do (way too easy to spoof), it needs to be something that can only be done by SSH or the like I think. Enter the 20-letter password that only you know about - or reflash. The thief also has the option of reflashing - but most of them don't know how. If they did - they'd likely be able to earn better working with electronics/computers. If you really hate thieves, fill all free space inside the case with explosive. Send the stolen phone a sms containing the key for self-destruct mode. In this mode it explodes a few seconds after accepting a call - the maximum damage moment when you get both the hand and the head. I would not recommend this though. It'd be illegal most places, and you'd have to be really confident about programming the trigger. (And then there is static electricity...) A safer self-destruct mode would be to erase all the flashes, including the one in the gsm modem. No boot or usb-based reflash after that, and thieves will not likely bother trying a debug board to see if it can be fixed. If they are that good, they probably make a decent living unlocking/servicing other brands of phone already. Such a self-destruct might be useful when the phone is stolen on a trip and you don't want to follow the thief into a dubious and unknown district. And you probably don't have all the tracking equipment (extra gps phone) with you either.

i'm assuming we don't want to brick it, because the thief is not very likely to return the phone if it doesn't work, nor can we track it if it isn't charged.

Just out of curiosity, can the telco really do all that passive triangulation (or more importantly, can I) they talk about in the movies? :P They have to do some of that anyway, just to make mobile roaming work at all. A phone that is on but not in use, still talk to the towers regularly. This so they know what tower to use, _if_ a call suddenly comes in. Let the phone rest atop a bad FM radio, and you will hear this in the form on radio noise now and then. You will also hear noise immediately before a call or sms comes in. When the phone is heard by one or more towers, the telco knows that it is in an area near all those towers. The more towers that hear the phone, the smaller the area because towers are spread and their range overlap only partially. Some towers are directional. Some towers gets a better connection to the phone than others - the phone is likely closer to those. This information alone gives you a good idea of where it is, especially in cities where towers are packed densely. I seem to recall that the gsm protocol lets the telco adjust a phone's signal strength. They generally go as low as possible, so it won't cause unnecessary interference elsewhere. They can tell the phone to vary the strength in order to measure from several towers. If they have sufficiently precise timers, then they can measure the distance from several towers too. This takes advantage of the fact that radio waves move at the speed of light, and so they arrive at different towers at a different time. 3 or more towers can then pinpoint the phone location with great precision, using exactly the same sort of calculation as a GPS unit uses when finding its position based on timing differences between 3 or more satellites. A third option is highly directional antennas. I don't think telcos bother with that though. Expensive installations and not needed for normal operation. I don't know if they use precision timers, but they can definitely see how the thief roam around. When he goes home, the police may have an idea about who has a criminal record in that area. There is a program around that is supposed to look for a special keyword in a sms, and send a gps reading back. It didn't work when I tried it, but this appraoch can be developed into something more robust. Another other security idea: Send an SMS to put the phone in stolen modus. (Do that quickly, before they change the sim card.) Stolen mode: * Send gps coordinates regularly, by SMS to a configured number. * Send a copy of every sms sent and received to the same place. * Send the phone log whenever a call is made * Send details about any new SIM card inserted. * If there is enough disk space, record conversations and play them back to a configured number when the thief isn't using the phone. Could be interesting. Also, a stolen phone could wait for a special message. If you give it up because the telco and police won't bother - have the phone brick itself by wiping out its flash memory. Or better, change the boot to display This phone is stolen from . . . The thief throws it away - with luck, someone else finds and returns it.

Another idea of the like: The phone is about to be stolen by muggers, the owner uses some button combo (both buttons for 3 sec?) to enable a special lock mimicking a broken screen - displaying some colorful strips, changing when the phone is being tilted (that's about what it looks like when the connector strip is damaged). This should not go away with a reboot - random text scrolling through the screen may even help with the illusion of the phone being broken.

Re: Someone stole my Neo Freerunner... :(
Hi, sorry for you all that lost your phone, stolen or lost anyhow by being careless. I also had lost a phone, but not my FR :-) I read the thread, and think about my contract. I have no gprs as of my old phone didn't let me opening web or wap pages. I have some questions and ideas that are in my brain :-) Is there any way to use analog modem connections ? I don't know how much CPU power is needed but when possible a phone could send more data to a dedicated number we could provide for that. If a real modem connection couldn't be used, what about creating a tone modulation for the data to be send as a 'spoken' message to be send back to a number as a voice recorder. The voice recorder then (a Linux PC :-) could decode the data and store the data. All the data could be collected on a web service to probably get the bad guys behind to give that information to the police. The web service also could provide information about stolen devices, thus when a phone gets any wlan connection, it could check for stolen state. This is not that spoof able I think, because the web sevice may be as usual password protected. But the server could provide sms, mms or phone gateways for fallback options. More gateways could be provided by us. The new gateway information could be uploaded by interacting with the user (software updates :-) If a phone didn't have gprs, sms, mms, or wlan, sending prepared 'data voices' would be an option. It didn't need to send much at first to get an answer about the stolen state in that way. I think the recorded data could be decoded in both directions, you don't need much cpu power, because it will be unidirectional, or let the 'protocol' enough time between packed sent and anser packets for decoding. Doing an active voice call may save us the cost of callbacks or sending back sms. With a proper longtime protocol with long pauses or a better solution a lot could be done. Usually you could activate this when the sim card get's changed without any notice to the user. He should still use the phone a while to collect information. We then could start a preinstalled application to authenticate the sim card change. If not options are many. The PIN entry of the normal card could be replaced by the PIN you provide. The user then wouldn't realize it, but claims to enter the correct, we simply accept, but start the timer for the above actions. Or we leave the user in claim that the documentation of it's sim card provider doesn't seem to be correct and he/she must issue a call with the service provider. At that point, the service provider couldn't help for that special phone. The new 'user' HAS to contact the manufacturer and so on you probably get your phone back, because the manufacturer should request for sending back the phone. Getting the state of stolen, the phone could anyway send a message to a police station near the user with spd-say, after the 'anti-theft' server has located the next police station's telephone number with any of the above options sent back to the phone.

Re: Someone stole my Neo Freerunner... :(
This is an excellent idea. I've been wondering about this. If I had GPRS, I would SSH in (possible? Getting the IP would be tricky) and pull GPS coordinates. But I don't have GPRS. I think it would be good to implement some kind of SIM-based security, along with a way to send some kind of panic SMS. Both would activate some kind of daemon that pulls coords from GPS whenever possible and sends them back to you. Maybe have it call you at home and a TTS engine gives them to you if you can't get SMS without your phone. Just some ideas. Would be AWESOME to have a phone that works to return to its owner though.

Problem with gps is that its slow to get a fix, sometimes very slow, and the phone may (probably?) be indoors or a car much of the time - so waiting for a fix is going to be a problem. Trigger with an unknown SIM card. Send a first panic, I've been stolen! sms message with as much detail as possible pulled from the SIM card, network settings (iwlist eth0 scan - and at your end try and locate on the wifi location database) - say forward their SIM phonebook to yourself (maybe one sms per contact to burn up their credit :) Then background and wait for a gps fix ...

Re: Someone stole my Neo Freerunner... :(
Apparently yes: here in Oz you can go to your telco and get the phone disabled if its been stolen - (tahts the phone itself, not the SIM is prevented from connecting - via IMIE I think). The cops can get location info, thoughs it is apparently more like somewhere about there in accuracy. Thats why I suggested wifi location like Skyhook - I think gps is a really flakey solution (going by experience with the FR) - the likely hood of a flat battery before you get a fix in most scenarios is very high, and what if the user notices it - unless you start working like a rootkit and hiding the app, which is starting to get very sophisticated! So I think gps, while be good, but shouldnt be relied on. BillK On Sun, 2009-01-25 at 20:10 -0600, The Digital Pioneer wrote: Indeed, GPS fixes are tough to get, but they can be done.

I've already thought about something like that when I bought the device, primarily because street robberies are still very common in Russia, especially in Russia itself, i.e. outside Moscow. However, there is one serious problem with this: the device can be easily reflashed. And robbers usually do not use stolen phones themselves, but sell them to second-hand phone resellers, who usually have staff with educated engineers. And even if we had some protection for flashing, like password in u-boot, there is not much we can do about people who have access to JTAG and other sophisticated debugging hardware, and used to cracking (reflashing, unlocking, messing with IMEI, ...) proprietary phones with no documentation at all, like open wiki with step-by-step instructions. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
