Claim 0:
1. A method for protecting membership and data in secure multi-party computation and communication, the method comprising:
generating a padding dataset, a size of the padding dataset being determined based on a data privacy configuration;
up-sampling a first dataset with the padding dataset by inserting elements of the padding dataset and random elements into the first dataset;
transforming the first dataset;
dispatching the first dataset;
performing an intersection operation based on the first dataset and a second dataset to generate a third dataset;
generating a first share based on the third dataset; and
constructing a result based on the first share and a second share,
wherein the first dataset includes a first identification field and a second identification field, the first identification field having a higher priority than the second identification field, and
wherein the second dataset includes a third identification field and a fourth identification field, the third identification field having a higher priority than the fourth identification field.
