Abstract
An example method of controlling access to data stored in a plurality of autonomous data sources includes receiving a federated query including a plurality of source queries. The method also includes receiving a request to submit a source query to a target data source. The method further includes determining whether the request matches at least one rule stored in a rules database. A rule that includes a given query matches a request that includes the given query. The method also includes when it is determined that the request does not match a rule stored in the rules database, sending a communication to cause (i) the source query to be submitted to the data source, and (ii) an initial result of the source query to be masked. The initial result of the source query has the same structure as the masked result of the source query.
