Relation decomposition as a method of preserving data privacy in distributed spatial data warehouse
Marcin Gorawski, Szymon Panfil · Studia Informatica System and information technology · 2007
The article presents an implementation of the relation decomposition as a method of preserving data confidentiality in a new distributed spatial data warehouse architecture that we proposed. Each node in this new architecture has its own privacy preserving module which is able to communicate with other modules. It enables parallel query processing through all privacy preserving modules and as a result it shortens the time of query implementation in DSDW.
