Walmart Patents System for Accessing Medical Records Stored on a Blockchain
Big-box retailer Walmart has been awarded a patent for a system that is designed to store a patient’s vital medical records in a blockchain database.
The information can then be retrieved at the scene of an emergency when a patient is unresponsive and can’t communicate with first responders. To protect privacy the only medical information that is stored on the blockchain database is emergency-specific.
The system described in the Walmart patent titled “Obtaining a Medical Record Stored on a Blockchain from a Wearable Device” is comprised of three critical devices.
One of them is a wearable device which serves as the local storage medium for the blockchain database. Then there is a biometric scanner which is used to obtain the patient’s biometric signature and a Radio-Frequency Identification (RFID) scanner whose purpose is scanning the wearable device. In the patent, the retail giant proposes that the wearable device ideally be a bracelet.
According to the patent, the system will allow medical care personnel to be fully briefed on a patient’s vital medical records as well as medical information before the patient arrives at a particular facility. This will not only prove time-saving but also potentially life-saving.
