Can data recovered during a forensic analysis be used as evidence in court?
Yes, provided that the analysis has been conducted according to recognized forensic standards. For digital evidence to be admissible in a Swiss or European court, several conditions must be met:
- Guaranteed data integrity — the original media has not been modified (use of a hardware write blocker during acquisition)
- Traceability of the chain of custody — documentation of each manipulation from seizure to analysis
- Cryptographic hashing — MD5 and SHA-256 hash calculated at acquisition to prove integrity
- Certified expert report — written by an expert who can testify to their methodology
Our forensic reports are written according to ISO/IEC 27037 standards (identification and collection of digital evidence) and can be presented before Swiss and French jurisdictions.
