Imagine a scenario where multiple healthcare providers need to share information about potential contacts of a COVID-19 patient.With the Baseline Protocol, they can do so securely without revealing the patient's identity or other sensitive information directly.The protocol ensures that only the necessary data is shared, and that it is done in a way that protects individual privacy.

How Baseline Developers Propose DTL-Based Contact Tracing

Developers working on the Baseline Protocol have proposed a specific implementation for COVID-19 contact tracing.This implementation leverages the protocol's core capabilities to address the limitations of traditional and even some digital contact tracing methods.Here’s a breakdown of their approach:

Data anonymization: Personal information is anonymized and stored securely on a DLT.
Proximity detection: IoT devices or smartphones detect when individuals are in close proximity to each other.
Contact event recording: When a contact event occurs, a record is created on the DLT, linking the anonymized identities of the individuals involved.
Infection notification: If an individual tests positive for COVID-19, their contacts are notified without revealing their identity.
Data access control: Access to the data is strictly controlled and limited to authorized personnel.

This approach offers several advantages over traditional methods.The automation provided by IoT devices and DLT significantly reduces the time and effort required for contact tracing.The anonymization and data access control measures protect individual privacy.The DLT ensures the integrity and transparency of the data.Specifically, leading ConsenSys developer, John Wolpert, has highlighted security concerns with the approaches of Apple and Google, which the Baseline protocol aims to mitigate.The Baseline proposal emphasizes data minimization and cryptographic techniques to enhance privacy and security.

Addressing Security Flaws in Existing Proposals

The Baseline Protocol-based approach directly addresses several security flaws identified in other contact tracing proposals, such as those from Apple and Google.These flaws include:

Centralized data storage: Centralized storage creates a single point of failure and increases the risk of data breaches.The Baseline Protocol uses a decentralized DLT to distribute the data and reduce this risk.
Lack of transparency: Some proposals lack transparency, making it difficult to verify the security and privacy of the system.The open-source nature of the Baseline Protocol allows for transparency and accountability.
Insufficient data protection: Some proposals do not adequately protect the privacy of individuals' personal information.The Baseline Protocol uses anonymization and data access control measures to enhance privacy.

The Baseline Protocol aims to provide a more robust and secure foundation for digital contact tracing by addressing these vulnerabilities.It leverages the inherent security and privacy features of DLT to create a system that is both effective and trustworthy.
