Forensic analysis of the Android calendar

Calendar entries record appointments, meetings and reminders. As part of an IT forensic investigation, calendar artefacts can provide important clues regarding chronological sequences, planning and communication links.

TECHNICAL BACKGROUND

Technical Fundamentals

Android stores calendar information locally and – depending on the configuration – in synchronised accounts.

Forensically relevant artefacts include, amongst others:

  • •Calendar databases (e.g. calendar.db)
  • •Dates and events
  • •Recurring events
  • •Memories
  • •Participants and invitations
  • •Synchronisation information
  • •Timestamps and revision details
  • •SQLite databases
  • •Manufacturer- and app-specific calendar artefacts

The availability and structure of the data vary depending on the Android version, the manufacturer and the account service used.

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
Following a suitable forensic data backup, calendar databases, synchronisation information and metadata are analysed using recognised IT forensic tools and manual analysis. Calendar data is correlated with timestamps, contacts and other artefacts. All stages of the investigation are documented in a reproducible manner.
2
LanCologne produces expert reports for private individuals, as well as for companies and solicitors. Our reports have already been used in court proceedings. In some cases, we have been directly commissioned to produce IT forensic reports. Upon request, we can provide anonymised or redacted sample reports or extracts.

TYPICAL QUESTIONS

When is this analysis required?

  • ✔Which appointments were saved?
  • ✔Which accounts have been synchronised?
  • ✔Which memories and participants are documented?
  • ✔Can changes or deletions be traced?
  • ✔How significant are the existing artefacts?

LIMITATIONS & CONCLUSION

What you should know

Deleted appointments, disabled synchronisation or device-specific differences may limit the available data set. Individual calendar entries are always assessed within the overall technical context.

Calendar artefacts often provide valuable insights into chronological sequences and organisational structures. Only when combined with other technical data sources is it possible to carry out a reliable IT forensic assessment.
