OBD, Edge AI & Mobile Sensing
SafetyCoin turns an ordinary vehicle and phone into an edge safety sensor — capturing data, running analytics on-device, and protecting privacy by design.
Low-cost, edge-first data acquisition
SafetyCoin avoids expensive specialized hardware by combining the OBD-II port with a capable mobile device.
OBD-II Speed & Vehicle Data
Reads accurate speed and diagnostics directly from the vehicle's OBD-II port as ground-truth input.
Phone as Edge Processor
The mobile phone fuses GPS and motion sensors with vehicle data and runs analytics on-device.
Camera-Based Concepts
Distraction, seatbelt, and red-light awareness concepts using the device camera.
Harsh Event Detection
Detects harsh braking and acceleration events that indicate elevated trip risk.
From port and phone to safety signals
The OBD-II adapter streams vehicle speed and diagnostics, while the mobile phone contributes GPS and motion sensing. The phone acts as the edge processor: it fuses these inputs, detects harsh braking and acceleration events, and — where enabled — applies camera-based safety concepts such as distraction and seatbelt awareness.
Because analysis happens at the edge, only meaningful safety scores and events need to leave the device — keeping bandwidth low and privacy high.
- Process sensitive data on-device wherever possible
- Share scores and events, not raw camera feeds, by default
- Driver-aware data handling and clear consent
- Minimize and aggregate data sent to the cloud
