Abstract(in English) In this paper, we study a privacy-preserving logistic regression. We consider the situation that two users have different data. They want to calculate an L1 regularized estimator without showing their data each other. The protocol was proposed for such a situation. However, in each iteration, this protocol has to send information between two users until estimator has been converged. Furthermore, when we consider the case of logistic regression, we have to use iterative method to determine information to send and need much calculation time. We propose a protocol which guarantees equal security to existing protocol and reduces the number of times to send information and reduces calculation time.
