Abstract
In a method for loading media data (M) into a memory of a portable data carrier (10) connected to an external operator device (24), the data carrier (10) receives a loading job, an encrypted data transfer channel (50) is set up between the data carrier (10) and a trustworthy, non-local server (30) on which the media data (M) are held, and the media data (M) are transferred in encrypted form via the data transfer channel (50) and written to the memory of the data carrier (10). A data carrier (10) and a computer program product have corresponding features. In addition, an operator device (24) and a computer program product are provided that are configured to provide a user interface for initiating the method for loading the media data (M). The invention provides a technique for loading media data (M) into a portable data carrier (10), which technique prevents unauthorized copying of the media data (M).
