OpenTrace (BlueTrace)
An open-source protocol for privacy-preserving cross-border contact tracing.
Overview
BlueTrace is an open-source protocol, and OpenTrace is its open-source reference implementation, developed by the Singaporean Government for the TraceTogether app. It is not a standalone software tool but a protocol that allows mobile phones to log close contacts using Bluetooth in a decentralized and privacy-preserving manner. Public health authorities can adopt and build their own contact tracing applications on top of this protocol.
✨ Key Features
- Privacy-preserving design
- Decentralized contact logging on-device
- Use of Bluetooth for proximity detection
- Open-source protocol and implementation
- Cross-border interoperability
🎯 Key Differentiators
- Centralized model where encrypted contact logs are uploaded to a health authority for analysis
- Allows health authorities to reconstruct contact graphs
- Open-source and developed by a government
Unique Value: Provides a free, open-source, and privacy-conscious blueprint for building national-scale digital contact tracing applications.
🎯 Use Cases (2)
✅ Best For
- Singapore's TraceTogether app
- Australia's COVIDSafe app
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Organizations needing a complete case management system
- Manual, interview-based contact tracing
🏆 Alternatives
Differs from the GAEN API by allowing a central health authority to decrypt and analyze contact data, potentially providing more detailed insights than a fully decentralized model.
