Abstract: A system and method is described for correlating user data across a data border between regions. A method includes obtaining access to a first database of user data stored by a first data manager in a first region and obtaining access to a second database of user data stored by a second data manager in a second region. At least one event is identified that is triggered by a user or a data manager in the first or second region. The second database of user data is then analysed to identify a subset of user data for one or more users correlated with the event. The identified subset of user data is then compared with user data in the first database to obtain a matching subset of user data from the first database. The matching subset of user data is then reported from the first database to the first data manager.
