Method and system for providing privacy-preserving data analysis

A computing system for privacy-preserving data analysis, comprising:

• a communication module;
• a memory;
• and
• at least one processor connected to the memory and configured to execute one or more computer-readable programs included in the memory, wherein
• the at least one program further includes instructions for:
• receiving a data analysis request including data-to-be-analyzed from a client;
• homomorphically encrypting the data-to-be-analyzed using an encryption engine;
• uploading the homomorphically encrypted data-to-be-analyzed to a target path of a blockchain;
• decrypting an analysis result of the homomorphically encrypted data stored in a designated path of the blockchain by using the encryption engine;
• and
• providing decrypted analysis result to the client, wherein the analysis result of the homomorphically encrypted data is data analyzed by a worker linked to the blockchain, and stored in a designated path in association with the target path of the blockchain.
