Classification: CPC G | IPC G

Claim 6:
7. A differential privacy composition determination system in secure computation and communication of a dataset, the system comprising:
a memory to store the dataset; and
a processor to:
determine a differential privacy configuration that includes a first privacy parameter and a second privacy parameter;
determine a privacy loss distribution;
provide a number of composition operations K;
perform a K-fold convolution operation of the privacy loss distribution by:
performing a two-fold convolution operation of the privacy loss distribution using a hash map based on the privacy loss distribution, and
performing a two-fold convolution operation of an intermediate convolution result using the hash map when K is greater than two;

determine a third privacy parameter and a fourth privacy parameter for a differential privacy composition based on the differential privacy configuration, the privacy loss distribution, the number of composition operations, and a result of the K-fold convolution operation; and
control the dataset based on at least one of the third privacy parameter and the fourth privacy parameter to limit access to the dataset.
