Queries that use differential privacy
Queries that use differential privacy allow analysts and data scientists to retrieve aggregated information from a dataset while ensuring that the privacy of individual data points is protected. These queries are designed to add a controlled amount of noise to the query results, making it difficult to discern the contribution of any particular individual in the dataset.
Various types of queries can be performed using differential privacy. Some commonly used ones include the following:
- Count queries: These queries aim to determine the number of records that satisfy certain conditions in a dataset while preserving privacy. The query result is perturbed by adding noise to the true count, ensuring that individual contributions cannot be accurately determined.
- Sum queries: Sum queries involve calculating the sum of specific values in a dataset while maintaining privacy – for example, computing the total income of a group of individuals...
