A method for supplying a feature specification of at least one authentication feature connected with a product, wherein a central device deposits in a database of the central device the feature specification and a reference code linked with the feature specification and uniquely marks the product. Within the framework of a request of a checking device, the central device receives a comparison code of the product from the checking device and ascertains the requested feature specification in the database by identifying the reference code corresponding with the comparison code. The ascertained feature specification is transferred at least partly to the checking device. In a subsequent method for checking the authenticity of the product, the checking device verifies one or several of the authentication features of the product on the basis of the received feature specification.
