E-Maalkhana

Digital chain-of-custody for physical evidence — replacing decaying paper ledgers with a strict state-machine and cryptographic proof of integrity.

Police Maalkhanas operated as disorganized warehouses linked to decaying paper ledgers spanning 15+ years. Searching for specific evidence could take hours. Evidence degradation, loss, and tampering were systemic. Collapsed court prosecutions resulted when judges asked for custody documentation and officers produced only tattered registers with illegible entries.

Accountability

Every item tracked via QR/RFID-bound identity from seizure through disposal. Each transition requires digital authorization — no gap where an item exists without a documented custodian.

Efficiency

Officers locate items by case number, FIR reference, or date range in seconds. Bulk queries like 'all items pending forensic return for Thursday's hearing' are routine.

Security

Role-based authorization at every transition. A constable cannot authorize destruction; a forensic lab cannot mark items returned without receiving officer confirmation.

Judicial Integrity

Courts receive cryptographic proof that no record was altered. Chain-of-custody becomes a procedural guarantee, not a paper formality.

Search time dropped from hours to milliseconds. Judges access cryptographic chain-of-custody records for every evidence item. Prosecutions that collapsed on procedural grounds now proceed on digitally guaranteed evidentiary integrity.
