The homepage serves the exact marked PNG exported by the Ariadne Mark 0.7.2a1 image engine. It is an AI-generated fictional scene, not an authentic photograph of a historical event.
Try it yourself
- Download the exact marked PNG.
- Open the image playground and choose Verify hero image, or upload the downloaded PNG in Verify.
- The detector should recover
014d666b6aefef54. Its public example message identifies it as the Ariadne hero sample.
Verification performs watermark decoding on the uploaded pixels before looking up the recovered identifier. A filename, URL parameter or image hash is not used as a substitute for detection.

The source image was submitted to the real Mark endpoint on our Ariadne server. Mark serialized its PNG, decoded that exact output and only then returned it. A separate Verify request recovered the same ID and message. A negative check of the unmarked source recovered no ID. The build checks the published PNG hash against its sample metadata.

What this demonstrates
This is a watermark-only example. No C2PA signature is attached to this PNG. The full SDK provides the separate signed-provenance workflow, described in the quickstart and complete SDK samples.
The maintained public sample record is separate from visitor-created messages, which expire after seven days. Its text is a published example statement, not a cryptographic proof of who generated the image. One successful read-back is not a durability benchmark, a legal approval or proof that arbitrary edits preserve the mark.
