METHOD FOR PROVIDING DATA ANALYSIS SERVICE BY A SERVICE PROVIDER TO DATA OWNER AND RELATED DATA TRANSFORMATION METHOD FOR PRESERVING BUSINESS CONFIDENTIAL INFORMATION OF THE DATA OWNER

摘要

Methods for providing data analysis service by a service provider to a data owner are described. The data owner transmits training data to the data analysis service provider, and the latter computes a model from the training data. In one method, the service provider transmits the model back to the data owner, which uses the model to generate predictions from prediction input. In another method, the data owner further transmits prediction input to the service provider, and the latter uses the computed model and the prediction input to generate predictions and then transmits the predictions back to the data owner. Prior to transmitting the training data and the prediction input, the data owner performs variable name anonymization and a variable transformation on the training data and prediction data point to obscure the meaning of the variables in the data. This prevents possible misuse of the data owner's data by unauthorized parties.

主权项

1. A method implemented in a first server operated by a data owner and a second server operated by a data analysis service provider, comprising:
(a) the first server transmitting training data to the second server; (b) the second server analyzing the training data received from the first server using machine learning to develop a model; (c) the first server transmitting a prediction input to the second server; (d) the second server computing a prediction using the model developed in step (b) and the prediction input received from the first server; and (e) the second server transmitting the prediction to the first server.
