The system will allow medics to receive medical information from patients who are unable to communicate it themselves.
As Cointelegraph informs, the American giant of retail Walmart has received the patent for the system intended for storage of medical data in a blockchain using the portable device.
According to the document, the system will allow medics to receive medical information from patients who are unable to communicate it themselves. The patient's medical data will be stored in blockchain and emergency services will be able to access them using RFID scanner.
As it described in the patent, the principle of the system is as follows: on a patient device his private and public keys are stored. In a case of an emergency, physicians scan the device, then decrypt the patient's private key using a biometric signature obtained by scanning the patient himself and gain the access to the patient's medical data using a combination of a private and public key.
Hospitals and other health facilities will be able to exchange by the received medical data that will allow the staff to obtain the necessary information before the patient arrives if he moves from one medical institution to another.
Walmart has repeatedly appeared in the news about getting the patents related to blockchain technologies. For example, in April it was reported that the company had filed the patent applications for the security technology of payment data based on blockchain and for the technology of using blockchain to encrypt information about payments.
