Chain of Custody Protocol

From Raw Leak to Defensible Scoop in Three Stages

How investigative reporters and fact-checking bureaus verify confidential source documents before publication.

Step 01Chain of Custody
Intake & Cryptographic Hashing

Intake & Cryptographic Hashing

Upload confidential PDF leaks, whistle-blower files, or scanned memos. The intake engine immediately logs an immutable SHA-256 cryptographic provenance hash upon receipt.

Step 02Pixel & Archival Scrutiny
Multi-Factor Forensic Examination

Multi-Factor Forensic Examination

Error Level Analysis (ELA) scans for pixel splicing and pasted signatures, font dictionaries detect typography alterations, and vector search cross-checks 45+ years of gazettes.

Step 03Pre-Publication Clearance
Defensible Evidence Dossier

Defensible Evidence Dossier

Receive an explainable 0–100% confidence report, visual tamper heatmaps, primary archival citations, and a verified audit certificate ready for editorial and legal review.
