Abstract: With the development of industrial big data technologies, manufacturing enterprises collect and analyse production data to obtain optimization methods of forecasting and diagnosis. However, manufacturing companies are constrained by technical bottlenecks such as modelling and computing power, which make it difficult to analyse data efficiently. Manufacturing enterprises need to bear the risk of information leakage, and it is also difficult to guarantee that model performance is lossless, when cooperating with other participants. For these scenario problems, a multi-lossless linear model learning method based on data privacy preserving is proposed. Firstly, a multi-party collaborative computing framework is built and the one-way data encryption algorithm is designed to protect the privacy of the data. Each collaborator trains the linear model separately based on the encrypted data. Secondly, the study analyses the association properties of the linear model with the dataset, proposing a lossless aggregation algorithm for linear models. Finally, the method is validated on the typical industrial scenario dataset. The experimental results show that the proposed framework can obtain global models with lossless performance and achieve privacy security for the data holders.
