Frequently asked questions

Common questions about textual signature watermarking and leak investigation.

What is LeakLocked?
LeakLocked embeds individualized textual signatures into emails and documents so each recipient gets a unique copy with imperceptible forensic marks. The approach is protected by U.S. patents.
How does LeakLocked identify the source of a leak?
We auto-detect signature opportunities, generate a unique version per recipient, then match leaked text or OCR'd images against every sent copy and rank suspects by confidence.
How is this different from spacing-based watermarks?
Spacing tricks break when text is copied or reformatted. LeakLocked's patented plain-text signatures survive screenshots, photos, and partial excerpts.
Does LeakLocked work on screenshots or printouts?
Yes. AI-powered OCR extracts text from images, then signature patterns are matched against your sent versions.
Which platforms does LeakLocked support?
Microsoft 365 and Google Workspace today, with an Outlook add-in, PDF watermarking, API access, and enterprise SMTP relay for broader rollout.
Is the technology patented?
Yes. LeakLocked's core forensic watermarking methods are protected by United States patents, including US 12,333,033 B2. View our Patents page.
