The device includes at least one optoelectronic detection device that detects the at least one print image and creates a representation that includes a multiplicity of pixels. The device further includes a unit that evaluates brightness intensities of the pixels, that segments the representation into multiple fields that each are composed of pixels of the representation, and that provides each of these fields with a piece of position information. The unit also ascertains, in each of these fields of adjoining pixels, a difference in their respective brightness intensities, and displays the differences as a frequency distribution. A display device further displays the digital identifier of the respective copy of the relevant printed product in the form of a graphical and/or alphanumerical display."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Smartphone or tablet comprising a device for generating a digital identifier of a copy, including at least one print image of a printed product produced in a production system, and method for using this device","description":"In some examples, a smartphone or tablet includes a device able to generate a digital identifier of a copy that includes at least one print image.
