Abstract
A system replicates data stored in a source database to target databases of systems such as mobile devices. The source database stores data objects, for example, documents, media objects, and so on. The source system ensures that the data objects stored in a target database correspond to a set of data objects that can be accessed by the user associated with the target database as determined by an access control specification of the user. Accordingly, if the access control specification of the user changes, the source system performs data synchronization to modify the set of data objects stored on the target database. If the access control specification is modified to revoke the user's access to a set of data objects, the source system performs data synchronization to send information identifying the set of data objects with a request to remove the data objects from the target database.
