Overview
- Rutgers-led researchers introduced VitalID, a software system that authenticates XR headset users by reading tiny skull vibrations from breathing and heartbeats.
- Headset motion sensors already built into popular devices capture these patterns, enabling continuous identity checks without adding new hardware.
- In trials with 52 participants over 10 months on two headsets, VitalID verified the correct wearer more than 95% of the time and rejected impostors more than 98% of the time.
- The team designed filters that remove normal head and body movements so the models analyze only vibrations caused by vital signs.
- Rutgers filed a provisional patent and is offering licenses, with the prototype not yet on the market and spoof-resistance claims still needing broader validation.
