When a document leaks, know who leaked it.
Give every copy you share an invisible, unique fingerprint. When a page shows up where it should not, trace it back to the exact recipient, even from a printout or a photo.
How it works
Protect before you share
Each recipient gets their own invisibly fingerprinted copy.
Share like you always do
No workflow change. The fingerprint survives print, photo, and copy-paste.
Trace any leak
Upload the leaked fragment and get the recipient, session, and timestamp.
From leak to name
Shared copy
Each copy you send carries an invisible fingerprint unique to its recipient.
Leaked photo
A page turns up in a screenshot, a printout, or a photo of a screen.
Matched to recipient
Upload the fragment and get back the recipient, session, and timestamp.
Where this fits
Security and data handling
Your keys, your control
Signing keys are tied to your organization. Bring-your-own-key (BYOK) is available, so key custody can stay with your team.
Standards-based cryptography
Each protected copy carries a C2PA manifest signed with X.509 certificates, not a proprietary format. Anyone can verify the document without trusting us.
Audit trail on every operation
Every protect, share, and trace action is logged and exportable for your own records and reviews.
Evidence you can hand to counsel
Trace results export as evidence packages with timestamps and recipient mapping, ready for an internal investigation.
