J3M
Crowdsource with Confidence
J3M is an open video standard that uses smartphone sensors to tag footage with context and evidence of its authenticity. WITNESS and The Guardian Project received a 2013 Knight News Challenge award to develop the J3M standard and bring context and reliability to mobile video.
Citizens Become Sources
J3M-enhanced videos tell you:
- Who (every device has a unique signature)
- What (no frame of the video can be altered without changing its fingerprint)
- Where (data from GPS and cell tower sensors)
- When (you're notified as soon as the video is shot)
- How (what device)
- Why (that's where you come in!)
Noise Becomes Context
- Use J3M data to turn a deluge of videos into a story, map or visualization
- Create dynamic content that changes depending on when and where your audience is
- Easily discover and cross-reference footage of a news event, in real time or years later
