We make digital content provably authentic at the hardware level.
AI-generated media is indistinguishable from reality. Software detection doesn’t work. At mutual, we’re building cryptographic signing directly into camera hardware, so content is authenticated the moment it’s captured.
Corporate introduction: Introducing mutual
The Role #
We need someone to own the firmware stack: Linux bring-up to TrustZone secure world code to camera pipeline integration.
