If you mean this call numbers that are getting called by 0.5mio users per day). Simply compare who called number A during last year, and who also called number B during last year already reduces number of individuals to max 10. Then check which of those 10 individuals doesn't use her/his old IMEI anymore and here you are: old IMEI linked to new fake IMEI. With only 2 calls done from your new SIM and IMEI to your wife and your mother (or any other arbitrary two normal phone numbers you called before) then this doesn't relate to me, if I don't use calls/sms and I use only Internet. Then they need to filter who uses same Internet services as me. This case it's much harder to make sure that me is me, right? ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Nope, since your internet traffic is a way better richer fingerprint of you than the numbers you could call (or don't, according to your planned use) Logging in on a single forum or webmail-service or polling your mail via POP3 or registering with a VoIP registrar already suffices. Heck even a more or less arbitrary cookie left in your browser suffices. And as already explained a IMEI popping up out of nowhere is *always* highly suspicious and will usually already suffice to put you into the group of those 20 subjects that currently frequently use fake changing IMEIs. For the rest a rough geolocation will do to identify you as subject #8 of those 20 subjects. It's like you running the streets wearing a gorilla mask, and then changing your gorilla mask to a pig mask and then 100m further you swap that for a donkey mask. *Everybody* will look at you and there's not much doubt who you are, despite you never showing your real face. OOOH, I almost forgot: tell me which internet service you may use without a SIM you paid for. They will probably die from laughing about you when you constantly swap your IMEI without constantly swapping your SIM *and your geolocation* exactly same time. /j -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments (alas the above page got scrapped due to resignation(!!), so here some supplementary links:) http://www.georgedillon.com/web/html_email_is_evil.shtml http://www.nonhtmlmail.org/campaign.html http://www.georgedillon.com/web/html_email_is_evil_still.shtml http://www.gerstbach.at/2004/ascii/ (German) signature.asc Description: This is a digitally signed message part. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

No doubt, when doing IMEI change, many details should be considered. And no doubt, if mail/chat etc service providers cooperate with your local intelligence agency, then you are even more vulnerable. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
