Document security

Protect intellectual property at the source

Product development, M&A, and legal review all demand fluid information-sharing. LeakLocked individualizes every document copy with patented embedded textual signatures — so leaks are traceable without locking down access.

Trade secrets kept secret

Protection without disrupting your workflow

Unlike access controls that lock down sharing or spacing-based watermarks that break on copy-paste, LeakLocked embeds individualized textual signatures directly into PDFs and files — discreet, robust, and invisible to readers.

Plain-text signatures

Meaning preserved, identity embedded

LeakLocked varies interchangeable phrases and list orderings to create unique document copies per recipient. The content reads the same; the forensic signature profile does not.

Effortless remediation

Trace leaks in minutes, not months

Upload a leaked fragment — even a photo of a screen or a partial page — and LeakLocked matches it against every individualized copy you shared. Multi-layer signatures survive partial leaks.

Share confidently

Accountability without restrictive controls

Teams in product, legal, M&A, and executive communications can share sensitive documents cohesively. Optional visible footers reinforce that each copy is traceable.

Prevent, remediate, and build trust

Individualized textual signatures support the full lifecycle of sensitive document sharing — from deterrence through forensic investigation.

Prevent
Individualized marks on documents signal that the information is private and traceable — deterring careless sharing before it happens.
Remediate
When even a portion of watermarked content leaks via email, printout, or photo, LeakLocked identifies the source using multi-layer signature matching.
Increase trust
When sensitive files are marked and attributable, information flows more freely to those who need it — with accountability built in.

Trace leaks across every channel

Textual signatures survive format changes that defeat traditional access controls and spacing-based watermarks.

PDF leaks
Recipient-specific watermarks embedded at send time, matched during investigation.
Image leaks
Screenshots and exports analyzed with OCR, then matched against marked copies.
Photo leaks
Mobile photos of screens or printouts — text extracted and signature patterns compared.
Print leaks
Printed copies photographed and traced back through surviving textual signatures.

Forensic reports you can act on

Upload a leaked PDF fragment, screenshot, or photo and receive ranked match results against every individualized copy you shared — with transparent scoring for legal and security teams. Multi-layer signatures improve accuracy on partial leaks.
