VCAP Console

Check a file

Choose a sealed photo or clip, a copy that kept only its invisible mark, or a .vcap proof file. This page checks the file with everything this platform holds for its capture — the evidence attached since it was sent, the anchor read from the chain, the key's status from our log — and opens the trace of the capture it came from.

The file never leaves this page.

It is read and checked by your browser. Nothing is uploaded and this platform never sees the file or its verdict: what leaves the page is the capture identifier the file itself carries, used to fetch the capture's complete proof and its key's status, which your browser checks against the keys this page ships with.

Every file that declares an invisible mark, or carries no proof at all, is read for the mark. The detector that reads it, about 34 MB, is fetched from here the first time and checked against its pinned digest; the verdict waits for it.

No file chosen yet.

The same open-source check runs without us: public verifier.
