Abstract: Health records are one of the most critical aspects of providing effective medical treatment. They include details about a patient’s past illnesses, checkups, prescriptions, lab results, and treatments. Unfortunately, in many cases, these records are still kept on paper or stored in separate hospital databases. This creates several problems — records can be lost, damaged, or hard to share between different healthcare providers. This makes diagnosis slower, increases the chances of repeated tests, and can sometimes lead to improper treatment. To overcome these challenges, we propose a Blockchain and QR Code–based Health Record System. This system securely stores every patient’s health history on a blockchain, which is a decentralized, tamper-proof ledger. Blockchain technology ensures that once a
medical record is stored, it cannot be altered or deleted without proper authorization. This guarantees the accuracy, reliability, and permanence of medical data.Each patient in this system is assigned a unique QR code, which acts like a digital key to their medical history. This QR code can be printed or stored on the patient’s phone. When the patient visits a doctor, the doctor simply scans the QR code using a secure application. The scan instantly retrieves the patient’s complete health record from the blockchain — including previous diagnoses, lab results, prescriptions, and checkup history without the need for paperwork or manual data requests.
