A Decentralized System of Genome Secret Search Implemented with Fully Homomorphic Encryption
Yuri Yamamoto, Masato Oguchi · 2017
An outsourcing system for calculating the statistics of genome data has been proposed as a method for utilizing genomic data in bioinformatics research. Individual genome data need to be encrypted from the viewpoint of privacy protection. In previous research, a client/server system was proposed for the string search of genome sequences using fully homomorphic encryption. The authors also improved the query and calculation algorithms for taking more advanced statistics of the genomic data for use in the future. However, calculations using fully homomorphic encryption are highly complex. In this study, we proposed the implementation of a master/worker decentralized system on the server side of a string search system for the genome using fully homomorphic encryption. We propose a decentralized system that is operated in a cloud computing environment.
