METHOD, CARRIER, KEY AND SYSTEM TO SECURE AND READ SECURED DATA

摘要

A method of securing data on an information carrier in which a capacity of a total memory R of an information carrier, a data memory capacity for data to be secured on an information carrier, a capacity W of an unoccupied data memory part on an information carrier are determined; a verification key is determined, wherein such a key contains information concerning information carrier memory; data are saved on an information carrier. The information carrier containing the secured data, characterised in that it has a total capacity and an occupied memory part capacity of the information carrier, herein the total memory capacity R is a sum of the occupied memory part capacity D and the unoccupied memory part capacity W, wherein the data secured in the information carrier can be read with the help of the technical device serving to authorize access to the data and the verification key, wherein the verification key contains information on the memory of the information carrier.
