Forensic analysis of significant locations – Properly categorising significant locations on macOS
macOS can use Location Services to recognise places that are significant to the user. Apple describes Significant Locations as a feature that enables a Mac to identify such places and use them to provide context-sensitive information in apps such as Maps, Calendar and Reminders. Apple also points out that Significant Locations are encrypted and cannot be read by Apple.
For forensic analysis, this feature may be relevant as a potential location context. However, the actual availability of analysable data depends on the macOS version, device configuration, Apple ID synchronisation, encryption and the condition of the backed-up data. It should not be assumed that a complete or permanently preserved location history is available.
Why LanCologne?
Since its foundation, LanCologne has specialised in professional IT forensics. Our staff have decades of experience in the field of information technology and assist companies, solicitors, private individuals and, on a regular basis, the courts in the technical investigation of complex digital matters.
The examination is, as a matter of principle, carried out exclusively on a forensic copy, a forensic image or a data source captured in a technically equivalent manner that preserves the integrity of the evidence. The original evidence remains unchanged and is stored in a manner that preserves its integrity.
Our services
We check whether the data source, which has been recorded in a manner that ensures the integrity of the evidence, contains technically usable information on Significant Locations or associated location services. Where available, time and location data are cross-referenced with other data from Maps, Calendar, Reminders, Location Services and other case-specific data sources.
Any missing or inaccessible data is explicitly documented as a limitation. No locations are derived from configuration entries alone or from the general functional description.
Typical areas of application
This is how the forensic investigation is carried out
Once the evidence has been securely preserved, the first step is to determine which Location Services and Significant Locations-related information is present and accessible on the specific macOS system. Usable entries are then organised according to source, time stamp and location information.
The results are correlated with independent data sources. In doing so, we take into account that Apple allows users to delete their Significant Locations history and that location-based information may be encrypted or synchronised on a device- or account-specific basis.
Why is this area of investigation relevant to forensics?
In appropriate cases, ‘Significant Locations’ can provide additional context for the spatial contextualisation of digital events. However, this feature should not be equated with a guaranteed, complete GPS history.
Particularly in legal matters, it is crucial to distinguish between a stored location reference, a „significant“ location identified by the system, and conclusive proof of a specific person’s presence. The latter typically requires additional evidence.
