DATA CARRIER

摘要

The invention relates to a data carrier comprising a non-volatile electronic memory (2) for receiving large amounts of data and a microcontroller (3) which is suitable for carrying out cryptographic operations, whereby access to the memory (2) is only possible via the microcontroller (3). Said inventive data carrier is characterised in that an authentication of the user with respect to a data source takes place before data is stored in the memory (2) using said microcontroller (3).
