It was difficult to be properly aware of the back, and due to this, healing and prevention activities were inevitably weak. In addition, as various medical information is distributed and stored by each medical institution, it is difficult to exchange and integrate information between information, and it is difficult to immediately provide medical information desired by patients in real time.

Medical information for a given patient is stored only at the medical institution visited by the patient, so when the patient visits another medical institution, it is easy for the medical institution to receive medical information about the patient stored in the previous medical institution. Did not do it.

In medical practice dealing with the patient's life, clinical diagnosis occupies a large part in treating patients, and the development of medical technology is helping a lot in accurate clinical diagnosis, and its dependence will increase in the future. Although medical imaging equipment such as Computer Tomograph (CT) and Magnetic Resonance Imagine MRI have become essential equipment in modern medicine, medical services have been used to detect abnormal areas of patients with medical imaging equipment. By taking a picture, printing it on a film, and passing it to the patient's doctor, a lot of time and manpower are invested until the final clinical diagnosis is made, so not only inefficient resource management, but also the hospital's finances are never helpful. I couldn't get the exact treatment.

Referring to FIG. 2, the user device 10 transmits raw data including at least one of medical information and genomic information to the mediation server 100 in step S110.

The intermediary server 100 receiving the raw data transmits the raw data with a request to store the raw data to the storage gateway 300 in step S120.

Then, the storage gateway 300 transmits the raw data to the data storage system 400 in step S130 to store the raw data. Accordingly, the data storage system 400 stores the raw data in a location allocated according to a preset rule, and generates location information indicating a location where the raw data is stored in the data storage system 400 in step S140, and then S150 The location information generated in step is transmitted to the storage gateway 300.

The storage gateway 300 receiving such location information transmits the location information to the mediation server 100 so that the mediation server 100 knows the location where the raw data is stored on the data storage system 400 in step S160.

When the mediation server 100 receives the location information, it generates index data in step S170. The index data includes at least location information indicating a location where raw data is stored on the data storage system 400. In addition, the index data may further include summary information generated by extracting at least some of the original raw data.

Then, the mediation server 100 extracts the location information of the raw data from the index data provided from the blockchain network 200 in step S240. Then, the mediation server 100 provides the location information extracted earlier in step S240 to the storage gateway 300 to request raw data corresponding to the location information.

When the storage gateway 300 receives a request for the raw data together with the location information from the intermediary server 100, the data storage system 400 detects the raw data based on the location information. That is, when the storage gateway 300 provides the location information to the data storage system 400 in step S250, the data storage system 400 detects the raw data corresponding to the location information in step S260, and detects the data in step S270. Raw data is provided to the storage gateway 300.

Accordingly, the storage gateway 300 may provide the raw data to the intermediary server 100 in step S280. Then, the mediation server 100 provides the raw data received from the storage gateway 300 to the user device 10 in step S290.
