US Patent 11675921 Device and method for secure private data aggregation

A computing system for enabling the analysis of multiple raw data sets whilst protecting the privacy of information within the raw data sets, the system comprising a plurality of synthetic data generators and a data hub. Each synthetic data generator is configured to: access a corresponding raw data set stored in a corresponding one of a plurality of raw data stores; produce, based on the corresponding raw data set, a synthetic data generator model configured to generate a synthetic data set representative of the corresponding raw data set; and push synthetic information including at least one of the corresponding synthetic data set and the synthetic data generator model to the data hub. The data hub is configured to store the synthetic information received from the synthetic data generators for access by one or more clients for analysis. The system is configured such that the data hub cannot directly access the raw data sets and such that the synthetic data information can only be pushed from the synthetic data generators to the data hub.
