Re: A new approach to Re: Itch3: Anti-lost/theft protection
The thing has bluetooth so it should be able to connect to the Wiimote. Using one instead of an internal accelerometer makes sense, because when you move your phone around, it's hard to keep looking at the screen.

This has actually been dealt with so we have examples like the Debian repositories which verify (gpg signatures, etc) packages so you know that the thing you are installing actually came from a place/person you trust. The other problem is just as present on regular PC-s, as you have trojans which, when run, change your dialup settings so you dial a high-price number on the other side the globe instead of your regular ISP. The second aspect is protection from malware. There are several solutions on this - proper user rights, virtualization, and filtering on the API level of the phone itself, best to combine all of these, since kernel logging won't help much if the trojan has root access and hides/works in the kernel as a module, for example. ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Image the suggestion in a previous message in this context: overtaxed calling number (for the profit of the victim). If someone sells you a phone with that enabled _on purpose_, so he would get both the price of the phone AND some money frauded from the unsuspecting buyer (and claim later that he either did not get any money or that the theft alarm was not on on purpose). If he does this on a small scale, he could even get away unnoticed for months or years sipping a few $ per month from the real victim which is in that case the new owner of the phone. That's one of the main reasons why proactive theft reactions, especially financial, are NOT really an option. > In this case, when you buy on ebay, you do have to receive the prove > that the phone is not stolen, in other case (even if I'm not a lower), > the buyer is too in fault... Since in our case it is already a second hand item proof of purchase is not readily available on most of the ebay items in that category - not many customers keep the papers, or even boxes that came with the phone. Sure, you can say that it is unwise or even illegal, but many of the used items on ebay have absolutely no 'proof of ownership' (do you ask proof of ownership on a garage sale or a flea market ?). ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: A new approach to Re: Itch3: Anti-lost/theft protection
Caveat emptor. Possession of stolen property is still a crime where I live, even if you didn't do the actual stealing. That said, I agree that attempting to rack up a large bill will not prevent theft nor lead to the return of the phone. Any anti-theft mechanisms should focus on locating the phone. We could maybe have the option of disabling the phone. But the only way to disable this open-source phone would be with some hardware lock. I don't particularly like the idea that my phone could be locked. Even if it should only happen to a thief, if it has the capability, it could be abused. We're treading too closely to the blasphemous idea of "trusted computing". -Steven On 2/28/07, Attila Csipa <[EMAIL PROTECTED]> wrote: A lot of ideas have been written on anti theft protection, but much of it from a geek/user's standpoint, and almost completely forgetting the possible ramifications of the suggested techniques.
