The mark, in detail.

Every delivery carries two things: a visible signature the buyer can see, and a separate hidden forensic layer they can't. The hidden layer is embedded in the frequency components of the file itself - not in metadata, and not as a visible label alone. That distinction matters: metadata gets stripped by almost anything - a screenshot, a re-upload, a platform re-encode - while a signal carried in the content's own pixel and frequency data tends to survive ordinary handling much better.

• Two layers, not oneA visible signature so the buyer knows the copy is theirs, and a hidden layer they can't see or strip out with a metadata tool.
• One mark per deliveryNot per creator, not per batch - per single sale. Two buyers of the same file get two differently marked copies.
• Not a file tagThe signal lives in the content signal itself. Stripping tags or remuxing the container doesn't touch it.

A delivery only unlocks once payment is confirmed, and the copy is marked at that moment - before it ever reaches the buyer. Any delivery can be revoked, and the link stops working immediately. What was already downloaded is out of everyone's hands at that point, which is exactly why the mark goes on before the file goes out, rather than being something we try to add after the fact.

Ordinary handling: a platform re-compressing the file, a straightforward re-save, a resize, a typical screen recording. Video marking spreads the signal across frames or segments, so a short repost - not just the whole file - can still carry enough to work with.

• Re-compression & re-saveThe kind of processing a platform or messaging app applies automatically on upload.
• Screen recordingA recording of a marked copy normally still carries the mark, so it still points back to the delivery it was played from.
• Partial clipsThe signal isn't concentrated in one spot - it's spread across the file, so a short excerpt isn't automatically unmarked.

Aggressive cropping, heavy blurring, or a copy re-rendered from scratch can degrade or remove the signal. A capture filmed off a second screen can lose it entirely.

sixx.me runs an ongoing automated check against known sources for the delivery token embedded in your content. You can also report a copy yourself - through the report form or your dashboard - if you spot one first. Either way, we check the copy for a decoded mark and compare it against delivery records. A strong match combines the decoded signal with context: which delivery it lines up with, timing, and where it was found.

This is forensic attribution - a review process producing evidence and a confidence level, not an automatic legal finding. What you get is an incident package you can hand to a platform, a takedown service, or your own lawyer. We're not a law firm and we don't file anything on your behalf.

sixx.me's own check is narrow and mechanical: it looks for the specific delivery token embedded in your content against known sources, not your name, your handle, or your reputation generally. That broader, continuous identity and handle monitoring across public sources is a separate capability under our sister product, Sentixx monitoring. If you want your name and handles watched across the wider internet - not just a token match on a specific delivery - that's what Sentixx monitoring is for.

The goal is a protected copy that looks the same as your source to the eye, while carrying a recoverable signal underneath. Your uploaded master is never the file that ships - every delivery is a freshly marked copy, so the same master can be reused across future sales. How well the signal survives afterward depends on the file itself: format, existing compression, and length for video.
