- Abstract
Aiming at the problem of effectively protecting user privacy data, we proposed a privacy-preserving logistic regression training scheme based on two-party secure computation to complete the joint modeling work of multiple data parties. Firstly, the scheme optimized the generation process of the multiplicative triplet to reduce the time required in the offline phase. Secondly, we replaced the activation functions that were difficult to calculate in secure multi-party computation with approximate functions. Finally, we vectorized the proposed protocols and accelerated the local matrix computation by using CUDA (compute unified device architecture). The experimental results of using different datasets to test the privacy-preserving logistic regression performance in both local and wide area networks show that the scheme can enable the model to converge in a short time and increase the possibility of solving privacy-preserving machine learning related problems in real world.
