Abstract
A method for producing, by means of a master mould, an optical registration carrier which is provided with at least one programme which comprises information stored in the form of variations in a physical parameter. A master mould is made by means of an encoder and a laser beam recorder, wherein the laser beam recorder is driven from the encoder for storing at least said programme on the master mould. Random verification positions are generated thereby, after which coordinates of the verification positions are encrypted into verification information. The verification information is stored in the programme and verification effects are stored at said verification positions.
