Digital Contact Tracing: Large-scale Geolocation Data as an Alternative to Bluetooth-based Apps' Failure

Introduction: Currently deployed mobile contact-tracking applications have failed as an effective solution in the context of the COVID-19 pandemic. None of them have succeeded in attracting the number of active users required for efficient operation. Objectives: expand the definition of digital contact tracing systems. Methodology: A protocol for contact tracking using location provider information has been proposed. The protocol has been implemented, and its performance has been measured. Results: the solution has been implemented, which in addition to being efficient guarantees the privacy of users. Conclusion: The presented solution would allow contact tracing, and with sufficient efficiency to scale correctly.
