Information Processing Method, Information Processing System, and Computer Readable Medium

An information processing method for distribution medical data, comprising:

• accepting, by a first device of a patient, agreement operation on providing of medical data relevant to a medical examination of the patient to a storage opened by any device;
• accepting, by the first device, verification data for authenticity of the medical data;
• transmitting the medical data for which the agreement and the verification can be accepted to a second device that is used in a medical institute of a diagnosis destination of the patient, with a measurement result by a measurement device measuring vitals of the patient, identification data of the measurement device, and reliability data indicating a degree of reliability of the measurement result;
• storing, by the second device, the medical data for which the agreement and the verification can be accepted in the storage;
• minting, by a smart contract of a blockchain system, a plurality of non-fungible tokens (NFTs) including an address for accessing the stored medical data for a blockchain account of the patient in the blockchain system, within a predetermined number of times of minting;
• accepting, by the smart contract, a purchase of the NFT from a third device of another person, and
• allowing, by the smart contract, an access to the medical data from a device of an NFT owner of the NFT if the device if it is successfully authenticated as being the device of the NFT owner.

The information processing system for distribution medical data, comprising:

• a first device of a patient;
• a second device that is used in a medical institute of a diagnosis destination of the patient;
• and
• a blockchain system in which each of the patient and the medical institute has a blockchain account,
• wherein
• the first device accepts agreement operation on providing of medical data relevant to a medical examination of the patient to a storage opened by any device;
• the first device accepts verification data for authenticity of the medical data;
• the first device transmits the medical data for which the agreement and the verification can be accepted to a second device that is used in a medical institute of a diagnosis destination of the patient, with a measurement result by a measurement device measuring vitals of the patient, identification data of the measurement device, and reliability data indicating a degree of reliability of the measurement result;
• the second device executes a process of storing the medical data for which the agreement and the verification can be accepted in the storage;
• a smart contract of the blockchain system mints a plurality of non-fungible tokens (NFTs) including an address for accessing the stored medical data for a blockchain account of the patient in the blockchain system, within a predetermined number of times of minting;
• the smart contract accepts a purchase of the NFT from a third device of another person, and
• the smart contract allows an access to the medical data from a device of an NFT owner if the device if it is successfully authenticated as being the device of the NFT owner.

A non-transitory computer readable medium storing a program that cases a computer which is a node in a blockchain system, as a smart contract, to execute processing of:

• the smart contract being called when an addition request for storing medical data relevant to a medical examination of a patient in a storage is broadcast,
• minting a plurality of NFTs including an address for accessing the medical data on the storage including a measurement result by a measurement device measuring vitals of the patient, identification data of the measurement device, and reliability data indicating a degree of reliability of the measurement result to a blockchain account of the patient, within a predetermined number of times of minting;
• accepting a purchase of the NFT from a third device of another person;
• and
• allowing an access to the medical data from a device of an NFT owner.
