So here are some common ones, but I really
want you to think outside the box.
So obviously, Uber, mapping, we talked about Waze.
Social media-- I talked about this several times
during this course.
Do not rely on any tagging or checking in on social media
unless you validate it.
What's really interesting on Facebook,
if you check in on Facebook on an iPhone,
there is a keylist file for every check-in that's
going to tell you how many miles or feet you
were from that location.
So for example, right now, if I check myself
in at some pub in London, if you look at that,
Facebook's going to honor it and say, Heather's
at a pub in London.
Really, I'm in California.
If you looked at the plist, it would show you
how far I am away from that check-in point
because when you go to check in, it scans nearby ones for you
that it knows of.
You can enter anything you want, and Facebook will show that.
But the truth is in the keylist.
If someone else tags you in something,
remember what I talked about.
You need to prove additional pieces of the puzzle
or find these artifacts that say, this is legitimate.
The person was actually at these.
Weather is amazing.
I talked about Zillow.
Yelp-- if you're looking for reviews
on things, an amazing artifact to find where someone was.
And then don't overlook health and fitness.
It's awesome.
Health and fitness knows the weather,
where you commonly exercise, who you exercise with.
All of these things are going to be trackable.
