What Happens When Surveillance Cameras Can Connect With Your Smartphone?

My wife still thinks it's creepy that her own phone knows where she is, so I think the public will generally be uncomfortable with this.

Also, I'm curious how they "blur" the behavior tracking/matching data. I suppose they could hash the data out so that you're either a match or not, but either that would make it difficult to match someone due to slight differences in the new data vs the record, or they'd account for that by having lower "resolution" of the data points collected, resulting in a higher number of successful matches but also false positives.
