Textual signatures that survive the real world
LeakLocked embeds plain-text digital signatures directly into confidential content — patented methods for interchangeable phrases, reordered lists, and multi-layer marks that preserve meaning while surviving copy-paste, reformatting, screenshots, and partial leaks.
Investigate
Here's how it works
When a leak happens, getting to the source should take minutes — not months. LeakLocked compares the leaked artifact against every marked copy you sent.
Step 1
Upload the leaked artifact
Paste leaked text, upload a screenshot, or provide an image of a printed or photographed document. LeakLocked extracts content with AI-powered OCR when needed.
Step 2
Match against sent versions
Point LeakLocked to the original message or document. We already have every individualized copy on file — each with its own unique textual signature profile.
Step 3
Get a ranked forensic report
LeakLocked scores each recipient's version by matched signature options — including partial leaks — and ranks suspects by confidence so your team can act on evidence.
The problem
Leaks are common — and getting easier
From Fortune 500 boardrooms to government agencies, internal emails and documents are leaked to social media, journalists, and competitors every day. A single photo of a screen can expose strategy, layoffs, or classified material.
