| Abstract(in English) | Uploading commercial data to third-party cloud services is popular in general. To further promote the active utilization of big data, outsourcing data mining systems that can execute statistical calculations using the uploaded data have been proposed. In this case, personal and sensitive data are required to be encrypted for privacy protection. In previous research, data protection using fully homomorphic encryption(FHE) was proposed for a client/server secret data mining system using the Apriori algorithm. However, this system requires much time because of the computational complexity of FHE calculations. Additionally, although frequent database updates occurred in the practical use of the system, the Apriori algorithm needs recalculation of the whole database at each update. In this study, to solve these two problems, we proposed the implementation of a master/worker distributed system using the FUP algorithm, which generates candidate item sets efficiently while updating the database. We improved execution time of the secure data mining system and made it suitable for practical use. |
