MOBILE FORENSICS

Mobile artefacts – calendars in IT forensics

Calendars are among the most important organisational tools on modern smartphones. They contain appointments, reminders, meetings and often also details of locations or participants. In IT forensics, calendar data provides valuable clues for reconstructing chronological sequences and can either support or refute statements made by those involved.

OUR APPROACH

This is how your examination will be carried out

A transparent process – from the initial enquiry to the handover of the report.

1
We analyse calendar databases, synchronisation information and timestamps, and cross-reference these with location data, communication records, photographs and other digital traces. This enables us to reconstruct a clear chronological sequence of events.

TYPICAL QUESTIONS

When is this analysis required?

  • ✔Which appointments were stored on the device?
  • ✔Has an appointment been changed or cancelled at a later date?
  • ✔Were there any memories or recurring events?
  • ✔Do the calendar entries match the location or contact details?
  • ✔Have appointments been synchronised with cloud services?

LIMITATIONS & CONCLUSION

What you should know

Calendar data may be stored locally or on cloud services. Changes resulting from synchronisation or the use of multiple devices can make evaluation more difficult. Furthermore, data structures differ between Apple, Google, Microsoft and other calendar services.

Calendar artefacts often provide valuable clues about planned or actual events. They are most useful as evidence when analysed in conjunction with other artefacts from a mobile IT forensic investigation.

Are cloud-based calendars also relevant?
Yes. Synchronised calendars may contain additional information or previous versions.
Can changes to appointments be tracked?
Depending on the data available, indications of changes or synchronisation processes can be identified.
Why are calendar dates compared with other artefacts?
Correlating the data with location information, messages or photos enhances the significance of the analysis.
