Google patents method to create fake data that protects privacy

Google describes a system that creates synthetic, or fake, datasets that mimic the statistical traits of real data without exposing individual records. The process involves identifying patterns in the original data, selecting a specific subset of those patterns, and using them to generate new data that preserves overall trends while hiding personal details.

Why it mattersThis could help companies share useful data for analysis without risking the privacy of the people in that data.

In the filing’s own words

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating synthetic datasets. In one aspect, a method includes receiving, from a data consumer, a dataset and one or more patterns. Each pattern defines statistical information characterizing at least a portion of data in the dataset. A search space that includes a set of candidate patterns is identified based on the dataset. A selection is made, using the dataset and the one or more patterns, from the set of candidate patterns, a proper subset of the candidate patterns to be used in generating a synthetic dataset. A differentially private synthetic dataset is generated based on the subset of patterns.

What exactly they claim (claim 1)

1. A method performed by one or more computers, the method comprising: receiving, from a data consumer, a dataset and one or more patterns, wherein each pattern defines statistical information characterizing at least a portion of data in the dataset; identifying, based on the dataset, a search space comprising a set of candidate patterns; selecting, using the dataset and the one or more patterns, from the set of candidate patterns, a proper subset of the candidate patterns to be used in generating a synthetic dataset; and generating a differentially private synthetic dataset based on the subset of patterns.
