MATCH — Pfizer
Clinical Trial Matching

How can patients share medical records without sacrificing privacy?

MATCH empowers individual patients to interact directly with institutions in the clinical trials they need. The Bitmark Protocol enables matching, at low transaction costs, while securing data privacy in clinical trials.

Pfizer turned to Bitmark to streamline the enrollment of candidates in clinical trials while protecting individuals' privacy. Bitmark built a blockchain-based trial matching system that uses metadata generated from health records to match individuals with clinical trials. In this process, neither Bitmark nor Pfizer stored individuals' health records or personally identifiable information, greatly reducing personal risk from data breaches.

This system uses the Bitmark Protocol to secure data provenance by creating a digital fingerprint of the individual's health records and designating control to the individual through a public key. The public key, in essence, is a randomized identifier that has no relationship to the individual or their personal information. However, the individual can easily verify their ownership of the key.

How It Works

  1. A sponsor publishes a recruitment call for a clinical trial.
  2. Patients signal their willingness to participate in the trial.
  3. The Bitmark Protocol generates metadata from the patient's health records for use in trial matching.
  4. Trial matching services process the metadata and recommend study participants that are likely to meet the enrollment criteria of recruiting clinical trials.

Benefits and Future Possibilities

  1. Standards for seamlessly interoperating with personal medical data sources, such as clinics, research facilities, personal accelerometers, and health monitoring, as well as research data consumers.
  2. The ability to inform individuals of research interests that could benefit from their data and allow data consumers to promote their research proposals.
  3. Creation of a variety of incentives for individuals from micropayments to awareness of how their data is used and the impact of research to which individuals have contributed their data.
  4. A security model that bolsters candidate confidence by reducing the risk of unintended data exposure and conforming to applicable law.

This simulated health data exchange is a step towards fulfilling Bitmark’s vision of a future where individuals can access health services and economic opportunities through their data without risk of privacy loss.
