System and method for implementing medical data exchange and medical claim settlement

A system for implementing medical data exchange and medical claim settlement via a Fast Healthcare Interoperability Resources (FHIR) standard data, communicatively connected to a server having a plurality of raw medical data of a first format stored thereon, the system comprises:

• a data exchange module configured to receive the plurality of raw medical data from the server and convert them into a plurality of FHIR authorized data in response to a mapping instruction via a converter built therein;
• a blockchain database communicatively connected to the data exchange module and configured to store the plurality of FHIR authorized data;
• a service-provider server communicatively connected to the data exchange module and the blockchain database, and is configured to provide a claim settlement based on the plurality of FHIR authorized data;
• and
• an authority management module communicatively connected to the data exchange module and the service-provider server, and is programmed with instructions to execute a method for managing each of the FHIR authorized data transmitted among the data exchange module, the blockchain database, and the service-provider server, wherein the method comprises,
• (a) receiving a first public key and a first private key from the server, and a second public key and a second private key from the service-provider server, respectively;
• (b) combining the first private key and the second public key of step (a) to produce a key;
• (c) encrypting each of the FHIR authorized data with the key produced in step (b) to produce a ciphered FHIR authorized data;
• (d) providing a signature to the ciphered FHIR authorized data of step (c) by use of the first private key, thereby producing a signed FHIR authorized data;
• (e) verifying the signed FHIR authorized data of step (d) by use of the first public key to validate and rescind the signature, thereby restoring the ciphered FHIR authorized data of step (c);
• and
• (f) decrypting the ciphered FHIR authorized data of step (e) with the key of step (b) to obtain the FHIR authorized data that has been decrypted, wherein the key is produced by combining the second private key and the first public key of step (a);
• wherein the FHIR standard data has a second format that differs from the first format of the plurality of raw medical data.
