FIELD: physics, computer engineering.
SUBSTANCE: invention relates to means of authenticating geometric codes on storage media. The method provides authentication of a code with geometric areas whose shapes and/or colours vary according to a message by creating variable geometric areas according to the message. A digital authentication code is generated to provide numeric values. An image of the geometric code areas is then formed, including a part of the digital authentication code in at least some of its geometric areas and/or in at least one space between geometric areas. Disruption of the digital authentication code is also generated.
EFFECT: improved copy protection of information on storage media.
