Re: [v6ops] Google Alert - IPv6

I think that misses the point. If you identify yourself to the phone, it knows that you are holding it. You might then pass it to someone else, who uses it. The phone doesn't know who is holding it, only that you unlocked it.

But that's not the point. The point is that someone *else* observing your phone's traffic or location data makes the assumption that the phone is with or being used by you. You didn't present your fingerprint to them; they are observing after the fact and making inferences.

Now, as an investigative tool, that makes sense - in a high percentage of cases, the person using your phone is you. So they can use that as a working assumption in the conduct of an investigation. But the working assumption doesn't prove anything, it only gives hints that have to be further verified to turn into proof.
