The way back to normal starts here
We all want to get out of the house. To reopen the economy. To feel secure again. Safe Paths builds tools that help communities flatten the curve of COVID-19 — together. CovidSafePaths.org
3. Digital contact tracing
Safe Places
• Notify if you have crossed paths
• Send alert that provides location of
where contact may have occurred
• Use phones to look for GPS and
Bluetooth based proximity
Safe Paths
9. COVID SafePaths App
• Log Personal Trails in Diary
• Compare with Public Infection Cases Datav1
• Compare with redacted trails of Infection
Cases from Public Health Deptv2
• Reducing burden on health officials
using Self-Report, Authenticate,
Computational methods
v3
11. Safe Places Web Tool
1. Patient 28 day trail with
health officials
2. The health official redacts PII
3. Anon/Aggr/Encrypted Trails
Faster and more accurate than
a traditional patient interview

15. Factor to Consider: Public Health IT Decisions
• Privacy-first
• Open Source
• Interoperable
• Multiple Language Support
• Support non-smartphone users/ Equity
• Ecosystem for Public Health
• Dashboard for hotspots/spread
• Modularity/ Ease of Use/ Integration
16. Google-Apple Proximity API: How it works
• Phones exchange keys by
whispering over Bluetooth
• Infected phone uploads keys to
beamed to server
• Health phone downloads
‘infected keys’ and find a match
with heard keys
18. 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
