摘要
Aggregate statistics are securely determined on private data by first sampling independent first and second data at one or more clients to obtain sampled data, wherein a sampling parameter substantially smaller than a length of the data. The sampled data are encrypted to obtain encrypted data, which are then combined. The combined encrypted data are randomized to obtain randomized data. At an authorized third-party processor, a joint distribution of the first and second data is estimated from the randomized encrypted data, such that a differential privacy requirement of the first and second is satisfied.
