Abstract
During manufacture and packaging of items whose authenticity is to be verified, the items are marked with individual item characteristics, and placed in a package.

A first package authentication code is generated, and the package is marked with the first package authentication code. During item authentication in the field, an image of the package and the marked items is captured, a second package authentication code and the individual item characteristics are extracted from the captured image, the extracted individual item characteristics are processed to generate a second item authentication code, and the authenticity of the marked items is verified by matching the first and second package authentication codes and by matching the first and second item authentication codes.
