Evidence Journey
The complete technical flow from crime scene to courtroom
Security & Integrity Layer
Every action is protected by multiple security layers
SHA-256
Cryptographic hashing creates a unique digital fingerprint for every piece of evidence
IPFS
Decentralized storage ensures evidence is distributed and cannot be lost or altered
Polygon Blockchain
Immutable ledger records every transaction with timestamp and validator confirmation
Audit Trail
Every action is logged with user identity, timestamp, and cryptographic signature
Chain of Custody
Complete traceability of evidence movement with handover verification at each step
Role Based Access
Granular permissions ensure users can only access what their role authorizes
Public Transparency
The Public Viewer role allows journalists, oversight committees, and the public to verify evidence integrity without accessing sensitive case details.
Confirm that evidence has been registered on the blockchain with a valid hash
Access case metadata without sensitive content or personal identifiers
Review the complete evidence movement log to ensure proper handling
Read-only access ensures the public cannot alter or interfere with evidence
“No single user can create, modify, approve, and hide evidence.”
Integrity
Evidence cannot be tampered with once recorded on the blockchain
Accountability
Every action is cryptographically signed and permanently logged
Transparency
Public verifiability without compromising sensitive case data
Court Readiness
All evidence is formatted and verified for admissibility in court
