Overview#
The Chain of Custody domain provides tamper-evident evidence tracking with cryptographic verification. It maintains a complete audit trail of all evidence handling actions including collection, transfer, analysis, and storage with hash-based integrity verification and digital signatures.
Key Features#
- Complete evidence lifecycle tracking with 10 action types (collected, transferred, stored, retrieved, analyzed, copied, returned, destroyed, sealed, unsealed)
- Cryptographic integrity verification with hash-before and hash-after state tracking
- Digital signature capture for non-repudiation of custody actions
- Independent verification system with third-party status tracking and dispute handling
- Chain linking for sequential verification across the evidence lifecycle
- Tamper detection alerting when integrity checks fail
- Export capability for legal documentation and court proceedings
- Chronological timeline view with entry counting
Use Cases#
- Tracking digital evidence from collection through forensic analysis to court presentation
- Verifying evidence integrity with independent third-party hash checks
- Documenting custody transfers with digital signatures for legal proceedings
- Generating court-admissible chain of custody reports for evidence items
Integration#
Integrates with evidence management, investigation, audit, digital asset, and forensics domains for end-to-end evidence lifecycle tracking.
