Secure identification of a product

摘要

In a method for marking a product first a product identification (12) is generated (S1) and applied (S5) onto the product (21). Subsequently the product identification (26) applied onto the product (21) is captured (S6) and stored (S8, S9) in a product database (11). Here in particular also an independent authentication feature (22) is designated (S3, S5) and applied (S6) together with the product identification (26) onto the product (21) and stored (S8, S9) in the product database (11).

主权项

1. A method for marking a manufactured product, the method comprising the steps:
generating a product identification corresponding to the product; performing an image transformation of the product identification based on a designated authentication feature to obtain a transformed product identification; performing an affine transformation of the transformed product identification to obtain a globally transformed product identification; applying the globally transformed product identification onto the product; capturing an image of at least a portion of the globally transformed product identification corresponding to the product to obtain captured product identification; and storing the captured product identification in a product database wherein the authentication feature is applied onto the product together with the product identification in such a fashion that the authentication feature cannot be derived from a copy of the applied product identification.
