PDF Ghost

PDF Ghost embeds an invisible, forensic‑grade fingerprint into each copy of a PDF that is distributed to a specific recipient. The fingerprint is hidden across metadata, content and structure, allowing it to survive typical modifications, format conversions and even screenshots. When a leaked document is uploaded, the system scans it for these hidden identifiers and produces an audit trail that links the file back to the original recipient.

The workflow consists of three steps: upload the confidential PDF and define the intended recipients, generate a uniquely fingerprinted version for each recipient, and distribute the files securely. If a copy later appears outside the authorized channel, the user can submit the suspect file for analysis and receive a report that pinpoints the source of the leak.

Targeted at legal firms, financial services, healthcare providers and corporate security teams, PDF Ghost is positioned as a tool for protecting confidential documents and meeting regulatory requirements such as GDPR and HIPAA. The platform offers encrypted processing and end‑to‑end security while providing forensic evidence for leak investigations.
