An open-source protocol for privacy-preserving cross-border contact tracing.

Visit Website →

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)

Powering national digital contact tracing applications Anonymous exposure notification systems

✅ 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

Google/Apple Exposure Notification (GAEN) API

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.
