<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Hi,</div><div><br class="webkit-block-placeholder"></div><div>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 :-)</div><div><br class="webkit-block-placeholder"></div><div>I read the thread, and think about my contract. I have no gprs as of my old phone didn't let me opening</div><div>web or wap pages.</div><div><br></div><div>I have some questions and ideas that are in my brain :-)</div><div><br class="webkit-block-placeholder"></div><div>Is there any way to use analog modem connections ?</div><div><br class="webkit-block-placeholder"></div><div>I don't know how much CPU power is needed but when possible a phone could send more data to a dedicated</div><div>number we could provide for that.</div><div><br class="webkit-block-placeholder"></div><div>If a real modem connection couldn't be used, what about creating a tone modulation for the data to be send</div><div>as a 'spoken' message to be send back to a number as a voice recorder.</div><div><br></div><div>The voice recorder then (a Linux PC :-) could decode the data and store the data.</div><div><br class="webkit-block-placeholder"></div><div><div>All the data could be collected on a web service to probably get the bad guys behind to give that information to</div></div><div>the police.</div><div><br class="webkit-block-placeholder"></div><div>The web service also could provide information about stolen devices, thus when a phone gets any wlan connection, </div><div>it could check for stolen state. This is not that spoof able I think, because the web sevice may be as usual password protected.</div><div>But the server could provide sms, mms or phone gateways for fallback options. More gateways could be provided by us.</div><div><br class="webkit-block-placeholder"></div><div>The new gateway information could be uploaded by interacting with the user (software updates :-)</div><div><br class="webkit-block-placeholder"></div><div><div>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</div></div><div>an answer about the stolen state in that way. I think the recorded data could be decoded in both directions, you don't need</div><div>much cpu power, because it will be unidirectional, or let the 'protocol' enough time between packed sent and anser packets</div><div>for decoding. </div><div><br class="webkit-block-placeholder"></div><div>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 </div><div>better solution a lot could be done.</div><div><br class="webkit-block-placeholder"></div><div>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</div><div>to collect information. We then could start a preinstalled application to authenticate the sim card change. If not options are many.</div><div><br class="webkit-block-placeholder"></div><div>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</div><div>the correct, we simply accept, but start the timer for the above actions.</div><div><br class="webkit-block-placeholder"></div><div>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</div><div>a call with the service provider.</div><div><br class="webkit-block-placeholder"></div><div>At that point, the service provider couldn't help for that special phone. The new 'user' HAS to contact the manufacturer and so on</div><div>you probably get your phone back, because the manufacturer should request for sending back the phone.</div><div><br class="webkit-block-placeholder"></div><div>Getting the state of stolen, the phone could anyway send a message to a police station near the user with spd-say, after</div><div>the 'anti-theft' server has located the next police station's telephone number with any of the above options sent back to the</div><div>phone. (Maybe with manual data entry of the phone numbers by us users with POI collection, hehe tangoGPS :-)</div><div><br class="webkit-block-placeholder"></div><div>That way the phone could help actively. Not only 'data voices' could be sent.</div><div><br class="webkit-block-placeholder"></div><div>Also the collected wlan, phone towers, GPS, voice, phone numbers and what else could help to locate the guys behind,</div><div>as the phones will walk up to the key guys before it would reselled. (Where they all are located would be very nice POI data) </div><div><br class="webkit-block-placeholder"></div><div>With that data, we could help the police.</div><div><br class="webkit-block-placeholder"></div><div>A note about the attack to people currently having your phone: They may not know, that they have a stolen phone, thus</div><div>you get to be a 'criminal' and beware, you may also get reatacked by the person :-)</div><div><br class="webkit-block-placeholder"></div><div>Giving the police the collected data, would propably help much more.</div><div><br class="webkit-block-placeholder"></div><div>What about all my stupid brain stuff ?</div><div><br class="webkit-block-placeholder"></div><div>Discuss about the possibilities - even stupid ideas as the old 'acustic coupler'. You don't really need all the modern GPRS stuff :-)</div><div>If that is possible also the cost of operation is not very high I think - even you change your card (you know to start a separate unlocker)</div><div><br></div><div>Lothar</div><div><br class="webkit-block-placeholder"></div><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate;
