02 Watermark

Ten starting points

Each preset sets the badge skin, placement, overlay and fingerprint together. Change anything afterwards — the preset is a starting point, not a lock.

The overlay is pointer-events safe — clicks pass straight through to the page.

Payload

Density

Each insertion is a framed block, so a decoder can recover the payload from a single copied paragraph. Brand + ID at full density adds real weight to the file — check the size counter.

Console signatureBranded line in the browser developer console

Copy attributionAppends a source line whenever text is copied Lock image draggingStops images being dragged out of the page Block right-click on imagesDeters casual saving. Off by default — it also frustrates real readers.

02 Removal

Strips every ATF mark from the file

Badge, tiled overlay, print marks, watermark CSS and scripts, JSON-LD publisher block, branded meta tags, the signed comment banner, root fingerprint attributes and any zero-width characters. Everything else in the document is left untouched.

Useful for handing a clean copy to a client, re-stamping under a different brand, or checking what a file was carrying. The Report tab lists exactly what came out.

03 Content signature

Sign with HMAC-SHA256Proves the content is yours and unchanged — a stamp nobody can forge without your key

Secret key

Remember key on this deviceStores it in this browser. Leave off on shared machines.

The key never enters the file — only the resulting digest does. Signing covers the page title, visible text, link targets and media sources; scripts and styling are excluded so reformatting does not break the signature. Lose the key and existing signatures can no longer be checked.

02 Provenance check

Reads the file, changes nothing

Scores a document against eleven independent markers and pulls out whatever identity data it finds: stamp ID, brand, source URL, author, the date it was signed, and the decoded zero-width fingerprint. The preview shows the file exactly as delivered.

Enter the same secret key above to check the content signature. Without it the signature is reported as present but unverified.

A high score with a missing badge is the interesting case — it means the visible mark was stripped while the embedded provenance survived. That combination is flagged as tampering.
