Authenticity Lens Smart Story Labs

New assessment

Check one video across technical, aesthetic and narrative markers, then record your decision. The file is analysed in this browser and is not uploaded.

Drop a video file to start

MP4, MOV and AVI files are checked for content credentials. WebM and MKV get metadata and measurement checks only.

No video to hand? Run a sample:

What happens to the file

  1. Fingerprint and content credentialsA SHA-256 fingerprint ties the record to this exact file. Any C2PA credential is read and its signer checked against the C2PA Trust List.
  2. Metadata and measurementsCapture device, encoding software, dates and encoding, plus measured shot changes and sound levels.
  3. Markers that applyYou say what the video claims to be; the aesthetic and narrative markers that apply are selected, each with its reason and the file's evidence.
  4. Your decision and the recordYou record the decision and your reasoning, and export it as JSON or PDF.

Nothing leaves this browser unless you export the record, search a claim on Google Fact Check Explorer, or consent to the optional AI-generation check for a file.

Authenticity Lens was selected for the Global Trust Challenge prototyping phase in June 2026 by the IEEE Standards Association, AI Commons and OECD.AI, in the AI Literacy and Civic Education cluster. It is a judgement-support tool, not authentication infrastructure: it builds people's capacity to assess synthetic video and does not certify content at source.

Three marker layers are checked in the order people weigh credibility: technical, then aesthetic, then narrative. Automated findings are one layer of evidence. The person makes the call.

Working in this prototype

  • Your own video, analysed entirely in the browser
  • C2PA content-credential reading and validation
  • Container metadata and encoding analysis
  • A SHA-256 fingerprint of the exact file assessed
  • Shot-change and sound-level measurement
  • Relevant aesthetic and narrative markers selected for each video, with reasons for those that don't apply
  • Timestamped flags and measured shot changes on the clip's timeline
  • A provenance inventory, a decision record and JSON, PDF or signed export
  • An optional AI-generation check, sent only with consent for each file, when connected on the server

Not in this prototype

  • Analysis from a pasted link (download the file first)
  • Trained forensic detection models (MSCA phase)
  • Invisible-watermark detection (MSCA phase, access-dependent)
  • Cross-cultural aesthetic and narrative models (MSCA phase)
  • Institutional storage of assessments (MSCA phase)

Everything else in Authenticity Lens runs in your browser. This check is different: it sends the video file to an outside service.

The result is one data point from a third-party model. It is never a verdict and doesn't change which markers apply.
