- Research project on Apple's Find My and Google's Find Hub networks.
- Find My network uses a billion Apple devices for geolocation via Bluetooth and ultra-wideband.
- Google's Find Hub network similarly crowdsources Android device locations.
- Investigation into how location is reported for disconnected devices.
- Exploration of potential for arbitrary Bluetooth devices to use these networks for free geolocation.
- Development of a custom protocol for unidirectional, secure data transmission over these networks.
- Analysis of privacy and security measures in both networks, including stalking alerts.
- Demonstration of data transmission capabilities, including text and images.
- Support for multiple hardware platforms (ESP32, Linux, nRF52 DK, TI microcontrollers).
- Integration of Reed-Solomon erasure correction for robust message reconstruction.
- Comparison of Apple's and Google's network protocols and their vulnerabilities.
- Potential deployment scenarios for the developed communication channel.
