Subject: Re: [IP] AT&T's 1.9-Trillion-Call Database
The database may go back decades but it's hardly comprehensive going
forward, lacking multiple other long-distance carriers, cellular
(including anonymous prepaid) calling, VoIP calling, computer-to-
computer connections like Google Talk, and cheap/anonymous calling
cards. I use a Costco calling card that costs $0.029/minute and isn't
the cheapest available. If I pay cash for it and don't recharge it,
it's not directly linked to me. (Hm, well, unless they track it from
my Costco membership number! But such cards are available for cash at
non-membership stores.) If I don't ever use it from a phone linked to
me, it remains anonymous.
All in all, calls are recorded in many disjoint databases. And people
seeking to be anonymous, or simply using technology or services which
by default anonymize, won't be tracked.
He was alluding to databases maintained at an AT&T data center in
Kansas, which now contain electronic records of 1.92 trillion
telephone
calls, going back decades.
