> But how do those apps know it's THE Tim Cook and not one of dozens of other guys named Tim Cook? Also, what if, and this is usually the case, most people don't have you as "Tim Cook" in their phonebooks, but as "Big Baws", "Honey Bunny" or "Timmeh 12 inches uncut"? If a lot of people have that same phone number in their contacts but only a handful have it as "Big Baws", "Honey Bunny" or "Timmeh 12 inches uncut" but do have as Tim Cook, or even have his job description, email address and other stuff attached to it too, it's safe to say it's a dead ringer to be Tim Cook, CEO of Apple, Inc.
