Classification: CPC G | IPC G

Claim 19:
20. A method comprising:
forming a test pattern composed of at least one value by randomly or pseudo-randomly generating, for each of one or more storage parameters, a respective value of the at least one value, wherein the at least one value of the test pattern identifies a location of a subarea of a memory area of an electronic storage of at least one electronic storage;
based on the formed test pattern:
obtaining, at a first point in time, data stored, at the first point in time, in the location identified by the test pattern;
generating a reference test variable using the data obtained at the first point in time; and
storing, in the electronic storage or in a different one of the at least one electronic storage (a) the test pattern or an identification of the test pattern and (b) the reference test variable;

based on the stored test pattern or the identification of the test pattern, obtaining, at a second point in time, data stored, at the second point in time, in the location identified by the test pattern;
generating a current test variable using the data obtained at the second point in time; and
determining whether an electronic data manipulation has occurred by comparing the current test variable to the reference test variable.
