Walmart Awarded with a Patent for Blockchain-Based Medical Records System

According to a patent published by the U.S. Patent and Trademark Office, Walmart which is one of the U.S retail giants has been awarded a patent for a system which can store medical records on a blockchain from a wearable device.

The document says the system will allow the medical professional to retrieve medical data from a patient which is not approved for the communication. The patient’s medical records will be stored on a blockchain and accessible by a device that is used by the patient that first responders could access with an RFID scanner. The patent further describes the principles of the system’s operation.

The Patent says:

“….receiving, by a processor of a computing system, an encrypted private key and a public key associated with the patient stored on a wearable device of the patient, in response to a scanning of the wearable device of the patient at a scene of an emergency, wherein the encrypted private key is decrypted by a biometric signature of the patient; obtaining, by the processor, the biometric signature of the patient by scanning a bodily feature of the patient; decrypting, by the processor, the encrypted private key using the biometric signature of the patient to determine a private key associated with the patient; and accessing, by the processor, the medical records of the patient, using a combination of the public key and the private key associated with the patient, to access a local storage medium of the wearable device.”

Moreover, the acquired medical information might be shared with hospitals and other healthcare entities, suggesting that if the patient is moved from one medical care organization to another, their data will be available for medical care personnel before the patient’s arrival.

Fortune reported that Walmart is thinking to buy health insurer Humana, a company where the retailers have an established relationship. The partnership with Humana would provide an essential data depository.
