SECURE DATA REPLICATION SYSTEMS AND METHODS

One method embodiment includes receiving input creating a data distribution restriction implemented to restrict distribution of data by publisher nodes located in at least one geographic or political area to subscriber nodes outside of the at least one geographic or political area. The method then queries a subscription repository storing data defining subscriptions to publisher node data events on publisher nodes located in the at least one geographic or political area to identify existing subscriptions to data events about the particular data by subscriber nodes located outside of the at least one geographic or political area. The method may then output the query results identifying existing subscriber node subscriptions contrary to the new or newly modified data distribution restriction. The received input may then be stored in a database such that subsequent changes are conditionally limited by the new or newly modified data distribution restriction.
