Abstract
A method for secure distribution of data in an interchange network, comprises having a network in which data records stored on at least one computer; and including an authorization service, where the authorization service grants a contractor access to at least a portion of the data records; and a watermarking module that adds one or more artificial records to said portion. The artificial records cannot be distinguished from the data records by the contractor and are valid for processing in the same way as the data records.
