Abstract

The method involves the use of an auxiliary arrangement, whereby read access to the confidential information is not possible without a special auxiliary arrangement. A first area essentially printed uniformly black with a pattern has a first line structure that has undergone a change in the areas to be read and that form a character or similar that can be read by superimposing a second line structure. Independent claims are also included for the following: an arrangement and a computer program for implementing the inventive method.
