Signed chain of custody with sha256 hashes.
Legal
Authenticate documents and digital evidence
Submit PDFs, emails, images, or ZIPs and receive a technical assessment with evidence citations and chain of custody.
Chat scenario
I received a PDF as evidence. I need to know if it was manipulated before using it in the file.
I calculate hashes, inspect metadata, PDF structure, OCR content, and editing signals without altering the original asset.
CAUTION
Evidence triage
- !Metadata conflicts with the declared date.
- !PDF objects were modified after initial creation.
I want the forensic dossier.
Dossier unlocked. The PDF includes NIST/ISO methodology, chain of custody, and calibrated conclusions.
Outcomes
Defensible dossier for legal discussion and court.
