Data processing method and system operatig in an environment where interplanetary file system is applied

A data processing method for a data processing system operating in an environment utilizing a decentralized distributed storage file system (InterPlanetary File System;

• IPFS), wherein the data processing system includes a user terminal, IPFS nodes interconnected and synchronized via a network, and a processing server, the method comprising:
• dividing at least one of personalized data into a plurality of fragment files and distributing and storing the at least one of personalized data, including the plurality of fragment files, across the IPFS nodes, each of the plurality of fragment files having CID information allocated based on the personalized data before division;
• receiving query information for a processing request regarding data generation referencing the at least one of personalized data through a generative artificial intelligence model;
• and
• generating response data corresponding to the query information by referencing the at least one of personalized data from an IPFS node that is physically adjacent to the processing server on which the generative artificial intelligence model operates, among the IPFS nodes.
