News Summary

• UK startup Lightmark claims it has developed a new approach to video authentication.
• It embeds a fingerprint of light into footage when it’s recorded, instead of trying to figure out a way of verifying authenticity afterwards.
• The system works by tweaking film set lighting in ways so small that the human eye can’t pick up – but crucially, cameras can.
• A UK patent application for the technology covering 15 core claims has already been filed, and the startup is looking to raise £1.5 million to move from prototype to early commercial deployments as soon as 2027.
