SYSTEM FOR PROTECTING A DATA PROCESSING DEVICE FROM UNAUTHORISED ACCESS

摘要

In a system for protecting a data processing device from unauthorised access, the user has a transponder designed as a data carrier with authorisation data. A reader associated with the transponder and connected to the station of the data processing device contactlessly polls data from the transponder when the transponder is within range of the reader. The reader is integrated into the operating device, the station itself or any peripheral equipment associated with the station. Both the authorisation data stored in the transponder and additional, user-specific identification data are evaluated before access is authorised. The station is only released for use when both the authorisation and identification data match comparison data stored in the data processing device.
