| Abstract(in English) | For promoting utilization of big data, outsourcing systems have been proposed in which transaction data such as purchase history of each company are stored and analyzed. In the system, third parties receive the data and execute calculations for data mining. From the viewpoint of privacy protection, the data will need to be concealed by an encryption. Therefore, in recent years, studies of the secure outsourcing systems utilizing fully homomorphic encryption (FHE) have increased. Since FHE is a cipher method that supports both the addition and multiplication operations of ciphertexts, it can make the system to calculate statistics in keeping the data encrypted. In previous research, a client/server system was proposed for data mining using FHE. The authors also improved the query and calculation algorithms for preparation to take more advanced statistics in the future. However, since the computational complexity of operations using FHE is high, an extremely long run time on the server side needs to be shortened. In this study, we proposed the decentralized system to divide tasks on the server side by item sets for the calculation of the Apriori algorithm and discussed the future tasks for further acceleration. |
