METHOD FOR ENFORCING DATA PRIVACY IN CLOUD COMPUTING SYSTEM

摘要

PURPOSE: A method for reinforcing data privacy in a cloud computing system is provided to protect privacy by disabling connection of attributes in a relational database(DB) based on fragmentation and encoding. CONSTITUTION: A confidential-restricting condition is set. The fragmentation of attributes is implemented about data generated in a cloud computing system according to the set confidential-restricting condition. The fragmented data is divided into a plurality of conversion pieces using a cipher block chaining mode. One conversion piece is stored in one DB, and remaining conversion pieces are stored in other DB to encode the conversion pieces.
