iPhone Forensic Timeline Reconstruction

Independent forensic reconstruction of iPhone activity — Messages, calls, location, KnowledgeC/Biome, Safari, application use, photos, and Unified Log — merged into a single second-by-second timeline suitable for depositions, trials, and settlement.

Quick Answer. iPhone timeline reconstruction merges every timestamped artifact into a single normalized dataset — Messages, calls, KnowledgeC /app/inFocus, Biome streams, Safari visits, photo capture, location visits, Wi-Fi and Bluetooth events, notifications, and lock/unlock — indexed to the second in UTC. The result is a defensible per-minute narrative that answers “what was the user doing at 14:22:17?” from many independent sources.

Source artifacts we merge

  • Messages — sms.db message table + WAL, message read/delivered/edit history
  • Calls — CallHistory.storedata + per-app VoIP logs
  • Location — routined Cache.sqlite, locationd Cache.sqlite, Photos EXIF, Maps history
  • App use — KnowledgeC /app/inFocus, Biome ApplicationActivity, applicationState.db
  • Browsing — Safari History.db, KnowledgeC /app/webUsage, downloads
  • Photos — Photos.sqlite ZASSET capture and edit timestamps
  • Lock/unlock — KnowledgeC /device/isLocked, /display/isBacklit
  • Wireless — Wi-Fi joins, Bluetooth pairings, AirDrop events
  • System — Unified Log entries from sysdiagnose bundles
  • Backups — Manifest.db events proving backup activity

Timezone normalization and DST

Every timestamp is converted to UTC and to the device’s local time as it existed at the moment of the event, using time-zone changes recorded in the Unified Log and com.apple.preferences.datetime.plist. This survives cross-examination about DST transitions, travel across time zones, and off-by-one arguments.

Detecting tampering and gaps

Merging independent artifacts exposes tampering. If sms.db shows a message at 14:22 but there is no matching KnowledgeC MobileSMS focus session, no unlock, no display-on, and no notification, the row deserves scrutiny — a forwarded/imported message or manual database edit is a candidate. Conversely, alignment of five or more independent artifacts makes the record almost impossible to fabricate.

Deliverables

  • Normalized CSV / SQL timeline of every event over the case window
  • Visual timeline (Gantt / Sankey / heat-map) for exhibits
  • Per-minute narrative report with citations to each source artifact
  • Written expert report suitable for FRE 702 admission

Frequently asked questions

How precise can the timeline be?

Sub-second for KnowledgeC and Unified Log entries; second-level for most SQLite artifacts; minute-level for external corroboration such as cell records.

What if the phone was off?

We show the exact power-off/on times from Unified Log and iBoot boot markers, and flag off-periods on the visual timeline.

Do you handle multiple devices in one timeline?

Yes — a common workflow is merging iPhone, iCloud, and Mac timelines onto one axis to answer cross-device questions.

How is the timeline authenticated?

Every entry is hash-linked to its source file/row so opposing experts can independently verify.
