Third-party apps are everywhere.
It is rare that you will come across a mobile device that
does not have third-party applications installed.
Most of them are associated with browser, social media,
and chat.
Location is another one.
So people will use them for weather,
to get directions, mapping applications.
But think behind the scenes on things
that you could actually get here.
So when we think of health, most people
don't think of health and location,
unless you're paying attention during this course,
and you read a lot of the things in the news.
Then, you may think, OK, the fact that the person has
their phone in their pocket when they
go on a walk, that's going to also get me location artifacts,
and it will.
But what about things like Uber?
What about searching for Airbnb or searching for restaurants?
All of those things know where you are
and where you want to search for.
So it could show intentions of getting to a location.
What about other exercise apps, not just iOS Health, or Samsung
Health, or anything like that?
Runkeeper, Nike Health-- all of these apps
that are helping you track progress in exercise
also know where you are.
I had some examples, I think, in Section 3,
at the end when I showed you the photo adjustments.
If you look closely at some of those screenshots in there,
you can see that I was using Slopes.
Slopes knows everywhere I've skied,
all the places I've been.
It detects all of these things for you.
So we want to see what these apps are actually
doing in the background that can assist us
with our forensic investigation.
