Covid Safe Paths
The document discusses the COVID Safe Paths initiative aimed at developing privacy-aware contact tracing solutions to promote public health while avoiding surveillance. It details various tools like the COVID SafePaths app and SafePlaces web tool, which utilize GPS and Bluetooth to enhance contact tracing and reduce the burden on health officials. The project emphasizes privacy, interoperability, and accessibility to support a resilient society as economies reopen.

GPS vs Bluetooth Tech •Needs multimodal (GPS + BT + WiFi) • BT requires large adoption (12% adoption = 1.44% encounters) • GPS scales linearly (12% adoption = 12% of sites on SafePlaces) • Inclusivity: Users who do not have smartphone can lean encounters over TV/SMS • False positives: person from neighboring office • False negatives: phones left behind risky behavior Not proximity but tracing • User: Context for belief, Where? (wearing mask? Shook hands?) • Public health needs: heat maps, spread analysis Beyond Tracing • Public health needs: Quarantine verification, Health verification, Immunity passport
