A method to create optically machine-readable identifiers on packaging films that cannot be easily copied or manipulated. The method involves generating an identifier by focusing a light beam onto a photosensitive layer on the film. This absorbs the light and causes a color change in the layer. The identifier can be read using a camera. A second layer is added that contains an optically detectable image. The user is asked to scan this image after scanning the identifier. The scanned images are compared and if they match, it indicates the packaging has not been tampered with.
