Third-party applications leave location artifacts in places one may not expect. While each application is different, a good example is the Day One application. This application is essentially a multimedia journal application that enables the user to post journal entries with attached photos and videos. I downloaded the application, created two journal entries, and attached a photo. The first journal entry included the text “first tomatoes from my garden.” I took a photo of the tomatoes in the application and was prompted to include my location in the photo. I selected to NOT save the location. Do you think the application respected my wishes?

When we examine the EXIF associated with the application, we will NOT see coordinates containing location information. But what happens when your phone thinks? When your phone suggests something or uses its brain, that data must be stored somewhere.
