Abstract(in English) | Putting genome data to practical use is drawing more attention as it becomes possible to analyze human genome data and apply its result recently. Large storages and computers are necessary to manage such a kind of big data, so outsourcing systems will be popular which receive some inquiries from users and execute calculations on cloud. However, cloud environment is not secure, because it is connected to the Internet and accessed by an indefinite number of people. Genome data is personal information, and in order to protect its privacy, we must encrypt these data. Although some secure search methods implemented with Fully Homomorphic Encryption (FHE), with which encrypted data can be calculable without decryption, was proposed, its calculation amount is still too large to put into practice. In this study, we applied decentralized processing to FHE calculation on the server side of the system proposed in a prior study by dividing and distributing database and discussed the future tasks for further acceleration. |
