System and method for access control for data of heterogeneous origin
Systems and methods are provided for controlling access to data of heterogeneous origin. A system creates combined access rights from access rights and other access rights for combined data that includes data and other data. The system receives a request to access data that is part of the combined data. The system determines whether to provide access to at least part of the data based on access rights that are part of the combined access rights. The system provides access to at least part of the data in response to a determination to provide access to at least part of the data based on the access rights that are part of the combined access rights.
