Apple Probably Knows What You Did Last Summer

Tuesday, June 5th, 2018

“Significant Locations” are an important part of the evidence logged on iPhones. Forensic experts doing the acquisition will try accessing Significant Locations. At the same time, many iPhone users are completely unaware of the existence of this feature. What are Significant Locations, where are they stored, and how to extract them, and what value do they serve in investigations?

Privacy Issues

iOS 11 and iOS 12 after it supposedly come with a slew of privacy enhancements. When it comes to Significant Locations, what we see is quite the opposite. There is an unresolved privacy issue instead.

Speaking strictly of “significant locations”, iOS 10 and older versions used to retain this data no longer than 45 days. Older records would be purged from the device. In iOS 11.4, the current release, location data is kept for at least 120 days (or 4 months). Apple does not provide ANY information about how or when it collects your location data; moreover, there is no official statement about how this data is being used. The only article that we were able to discover is “Location Services & Privacy“. Have a look at the following quote:

Significant Locations – Your iPhone will keep track of places you have recently been, as well as how often and when you visited them, in order to learn places that are significant to you. This data is transmitted end-to-end encrypted between your iCloud connected devices and will not be shared without your consent. It will be used to provide you with personalized services, such as predictive traffic routing, and to build better Photos Memories.
