Abstract:
Implementations of this specification provide methods and apparatuses for oblivious data transfer between computing devices. An example method includes receiving, by a second computing device, an oblivious transfer from a first computing device. The first computing device splits feature data in a feature dataset into a plurality of sub-data and uses the plurality of sub-data as input, and the second computing device uses label data in a label dataset as input. The second computing device selects target sub-data from the plurality of sub-data input by the first computing device, and determines a first summation result of the selected target sub-data. The second computing device receives from the first computing device a second summation result of the one or more splitting parameters in the splitting parameter set, and calculates a statistical indicator based on the first summation result and the second summation result.
