Abstract
Monitoring and limiting data distribution is accomplished when a request for transportation of distribution data is received. Upon receiving the request, an attempt is made to identify a data distributor (105-108). If the data distributor (105-108) is identified, the request is routed to the distributor, such that the distributor may route the requested data to a requesting unit (116). Each transportation of data to a user is monitored and compiled into data use information by a monitoring apparatus (103). This information is routed to a data owner (109), who, upon reviewing the information, may provide instructions for future data transmissions.
