This invention is a system and method for a matching system that cross-references patients anonymously with doctors and pharmacies. The invention uses patient-unique biometrics, such as fingerprinting, retinal scanning, or another such unique identifier, for patient identification and verification without revealing a patient's name or other personal information. The system tracks patient prescriptions and produces alerts to indicate potential problems, such as drug interactions or possible fraudulent behavior. The system utilizes the biometric data of the prescribing physician as authorization of the prescription. The system can produce a traceable paper trail, for investigation or prosecution, and protects the medical industry, patients, and the public from the consequences of doctor shopping.
