Security & Hacking: DEFCON 20 "Can You Track Me Now?"
DEFCON 20: Can You Track Me Now? Government And Corporate Surveillance Of Mobile Geo-Location Data
This was posted on Youtube November 22, 2012, so was well before Snowden release of information in May of 2013.
Main emphasis of this talk was tracking of cell phones.
But Christopher Soghoian briefly covers, at 31:05, that both Android (Google) & iOS (Apple) device encryption can be defeated by Google & Apple respectively.
This is a service they provide for Law Enforcement & other Government agencies.
Google can force a password reset for Android device, they don't require physical access.
Apple appears to use what Soghoian calls a "Master Skeleton key," they require departments to provide actual device (ie physical access). They then provide unencrypted data on a CD, while device remains encrypted.
I wonder if they might actually need device to decrypt data with way devices since iPhone 4S & iPad 2 have been designed (they have hardware based encryption).
Entire video is worth watching, though it is rather long, they joke about having 3 different audience during the course of the talk.
