Health Data: Protecting Sensitive Information

Problem: The rise of wearable health devices (like fitness trackers) is generating vast amounts of sensitive health data. Traditional systems leave this data vulnerable to privacy breaches, as shown in the 2021 data leak affecting 61 million Fitbit and Apple Watch users.

Why Current Systems Fail:

  • Centralized storage makes health data vulnerable to breaches and unauthorized access.
  • Legal frameworks are often slow to adapt to emerging privacy needs, leaving individuals’ data exposed.

Solution: Verifiable Credentials for Health Data​

Using Verifiable Credentials (VCs), individuals can store and control their health data securely on their own devices, choosing who can access it and when.

How It Works​

  1. Issuance: A healthcare provider issues a VC containing health data to the individual (e.g., athlete, patient).
  2. Storage: The credential is stored in the individual’s digital wallet.
  3. Presentation: The individual decides what data to share and with whom (e.g., a doctor or coach), without exposing all of their personal health information.
  4. Verification: The recipient (e.g., a healthcare provider) verifies the authenticity of the data without accessing unnecessary personal details.

Benefits​

  • Enhanced Privacy: Individuals maintain control over their data, sharing only what’s necessary.
  • Data Integrity: VCs are tamper-proof, ensuring that health data cannot be altered.
  • Reduced Liability: Healthcare providers don’t need to store sensitive data, reducing risks and costs.
