Description

Verify image and video content provenance. Recovers the watermark locally and checks the creator's signature. Mysterion Verify checks whether images and videos on any web page carry a valid Mysterion cryptographic signature. Right-click any image or video and choose Verify with Mysterion. The extension recovers the embedded steganographic watermark locally in your browser using WebAssembly, then confirms the creator's post-quantum signature and RFC 3161 timestamp against the Mysterion platform. A badge shows the verdict: verified, transformed, altered, or unsigned. Content you did not create verifies exactly as content you did. Your files never leave your device. Only a cryptographic hash is sent for lookup.
