Abstract (en)
[origin: DE10020050A1] The local system [10] has a coding unit [22] for embedding protected data in another document. This operates with a processing unit [26] to control extraction of the data. Data is stored in a main memory [16] and is transmitted via an external network [12] to a host computer [30].
