Abstract
Methods and systems for protecting membership privacy in multi-identification secure computation and communication are provided. The method includes providing a dataset having a first set of membership identifications and a second set of membership identifications, determining a number N based on a data privacy configuration, generating and shuffling a first padding dataset, and up-sampling the first set of membership identifications with a first N elements of the shuffled first padding dataset. The method also includes inserting a first N random membership-identification elements to the second set of membership identifications, generating and shuffling a second padding dataset, up-sampling the inserted second set of membership identifications with a first N elements of the shuffled second padding dataset. The method further includes performing an intersection operation based on the up-sampled dataset and a received dataset.
