What is Chain of Custody?
Chain of custody is the documented record that tracks evidence from collection to courtroom. It includes:
- Who handled the evidence
- When they handled it
- What actions were taken with it
- Where it was transferred or accessed
Any break or gap in this chain can result in evidence being inadmissible in court.
Problems with Traditional Paper-Based Chain of Custody
Traditional evidence tracking systems have critical vulnerabilities:
- Human error: Officers forget to log actions or make documentation mistakes
- Missing records: Paper forms get lost, damaged, or misplaced
- Easy to tamper: Physical records can be altered or destroyed without detection
- Difficult to verify: No way to prove authenticity or detect changes
- Time-consuming: Manual documentation slows down investigations
- Incomplete trails: Actions may go unrecorded due to oversight
How DEMS Creates Tamper-Proof Audit Trails
Automatic Action Logging
DEMS automatically captures every interaction with digital evidence:
- User identity and credentials
- Precise timestamp (date and time)
- Specific action performed (view, download, copy, edit, transfer, share)
- IP address and device information
- System access details
Immutable Record Technology
DEMS uses advanced cryptographic security to prevent tampering:
- Each logged action is encrypted immediately upon recording
- Records are linked using hashing mechanisms
- Any attempt to alter or delete entries breaks the cryptographic chain
- Tampering attempts are immediately detectable and flagged
- Not even system administrators can modify historical records
Real-Time Documentation
- Every action creates an instant, permanent entry
- No manual input required from officers, attorneys or admin staff
- Zero gaps in documentation
- Continuous monitoring from evidence intake to final disposition
