Witness — Anti-Deepfake Camera
A proof-of-concept for tamper-secure video capture: a Raspberry Pi and supplementary sensors wired together so that footage can be trusted after the fact, not just at the moment it’s shot.
- Cryptographic signing of captured footage, aimed at making after-the-fact tampering detectable rather than just discouraged.
- Sensor integration and data integrity checks at the hardware level, so the security guarantees don’t rely on software alone.
- GPS and data transfer pipeline to get signed footage off the device reliably.
