Subscriber Information
- SIM cards allow users to retain subscriber information when switching devices, offering convenience.
Evidence Cloning
- Cloning a SIM card preserves subscriber data for forensic purposes similarly to data imaging.
Data Recovery Limitations
- Deleted items like emails, texts, and photos cannot always be recovered from mobile devices.
Chain of Evidence
- The chain of evidence details the sequence of events and related evidence throughout a crime.
Temporal Evidence
- Temporal chains of evidence illustrate the chronological order of events in a crime scenario.
Causal Evidence
- Causal chains analyze events by establishing relationships of cause and effect among them.
Hybrid Crime Assessment
- Hybrid assessments consolidate crime elements into a single location and timeline to create a comprehensive view.
Synchronization and Accuracy
- Mobile devices are accurate time indicators, often synchronized with a network clock.
Connectivity Features
- Mobile devices can detect and connect to available Wi-Fi networks in proximity.
