See how your documents are protected

Explore interactive examples of our fingerprinting technology. Each document receives unique, invisible marks that are impossible to remove.

Interactive Demo

Choose a protection level

Select a level and see how fingerprint layers are applied to your document in real time.

In real documents, the fingerprints are completely invisible to the naked eye. Here they are exaggerated for demonstration.

Simplified simulation — actual fingerprints are invisible in the final document.

Technologies

17 fingerprinting techniques

Each technique adds an independent layer of protection. Combined, they create an unforgeable digital identity for each recipient.

Micro QR Code

Unique QR code per recipient, embedded at minimal size in strategic positions.

Nearly invisible (< 0.5cm)

Micro-Text

Text at 1-2pt with the recipient identifier, distributed along margins and between paragraphs.

Invisible without magnification

Micro-Dots

Sub-pixel dots in strategic positions encoding the unique fingerprint of each copy.

Invisible to the naked eye

PDF Metadata

Hidden information in the document structure, internal headers and XMP properties.

Hidden in document properties

Distributed Fingerprint

Fingerprint fragmented across multiple pages with redundancy for tamper resistance.

Distributed and redundant

Moiré Pattern

Interference pattern in the document background that encodes unique data per copy.

Invisible on screen, detectable on scan

…plus 11 more techniques including color channel steganography, content stream reorder, serial codes and more.

Shuffled copy

Same look, unique binary per recipient

TraceDocuments reorders the PDF's internal structure (xref shuffling) on every copy. The visible content is identical, but the MD5 hash changes — making it impossible to identify the leak source from the file alone.

Shuffled copy for another recipient

Same text, same layout, same page count. But the PDF internal objects were reordered, producing a completely different MD5. If this copy leaks, we know exactly who received it.

What changes in your document?

100% Invisible

Fingerprints do not alter the visual appearance or readability of the document.

Unique per recipient

Each downloaded copy has a unique combination of fingerprints.

Fully traceable

If a copy leaks, we identify the exact recipient who received it.

Tamper resistant

Multiple layers survive print, scan, screenshot and PDF conversion.

Before — Unprotected document

⚠ No protection — impossible to trace leaks

After — Protected with Trace DocumentsProtected

✓ 17 fingerprint layers — full traceability
