GenoPPML – a framework for genomic privacy-preserving machine learning

Abstract

We present a framework GenoPPML for privacy-preserving machine learning in the context of sensitive genomic data processing. The technology combines secure multiparty computation techniques based on the recently proposed Manticore secure multiparty computation framework for model training and fully homomorphic encryption based on TFHE for model inference. The framework was successfully used to solve breast cancer prediction problems on gene expression datasets coming from distinct private sources while preserving their privacy - the solution winning 1st place for both Tracks I and III of the genomic privacy competition iDASH'2020. Extensive benchmarks and comparisons to existing works are performed. Our 2-party logistic regression computation is $11\times$ faster than the one in De Cock et al. on the same dataset and it uses only a single CPU core.
