Abstract: Methods and systems for secure computation and communication are provided. The method includes transforming identifications of a first dataset using a first transforming scheme, and transforming attributes of the first dataset using a second transforming scheme. The method also includes dispatching the transformed first dataset, receiving a second dataset, transforming identifications of the received second dataset, dispatching the identifications of the transformed received second dataset, and receiving a set of identifications. The method further includes generating a first intersection of the received set of identifications and the transformed received second dataset, generating a first share based on the first intersection, receiving a second share, and constructing a result based on the first share and the second share.

Abstract: Methods and systems for evaluating privacy protection are provided. A method includes generating a first intersection of a first dataset and a second dataset. The method also includes determining a partition number based on the first dataset, the first intersection, and a number of iterations by: determining a privacy leakage for subsets of the first dataset based on the first dataset, the first intersection, and the number of iterations; and determining the partition number based on the privacy leakage for each of the subsets of the first dataset. The method further includes partitioning the first dataset into a first sub-dataset and a second sub-dataset using the partition number, and determining positive membership and negative membership for elements of the first sub-dataset in the second dataset and for elements of the second sub-dataset in the second dataset.
