How does DEMS improve chain of custody?

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
