FIELD: information technology.
SUBSTANCE: present invention relates to devices for limiting access to digital data stored on a data carrier. The technical outcome is achieved due to that permission for access to data is checked using a separate device, fitted on the controller board of the data carrier. Change in device parametres, which are program-accessible, can only be done using special software, which is part of the system for limiting access to data. For this purpose in the device there is an extra unit for analysing commands, which verifies authenticity of commands given by the software.
EFFECT: provision for limited access to sectors of a data carrier, distinguished by special attributes, and prevention of unauthorised altering of the attributes themselves.
