Abstract

Systems and methods for controlling data usage in a distributed environment among multiple entity domains. A method include steps of: receiving, in a local entity domain, a data consuming application comprising or identifying at least a first analytics task, wherein the first analytics task processes data inputs to produce first output data; determining availability of the data inputs; interpreting data usage policies, or data control policies, to determine atomic actions to be executed, wherein at least one of the data usage policies indicates that one of the data inputs for the first analytics task must remain in a remote entity domain; and executing the atomic actions, wherein the atomic actions include dispatching the first analytics task to the remote entity domain for remote execution of the first analytics task and receiving the first output data of the first analytics task from the remote entity domain.
