Title: METHOD AND APPARATUS FOR PROVING AN AUTHENTICATION OF AN ORIGINAL ITEM AND METHOD AND APPARATUS FOR DETERMINING AN AUTHENTICATION STATUS OF A SUSPECT ITEM
Abstract:
The present invention relates to a method, an apparatus and a use of an apparatus for proving an authentication of an original item (180) as well as to a hereto related method and apparatus (176) for determining an authentication status (172) of a suspect item (180), wherein a code is assigned to the item (180) according to a set of rules, wherein the code comprises a plurality of modules (118) arranged in an ideal image (150), wherein at least one barcode content of the item (180) is encoded within the plurality of modules (118), wherein at least one picture (1 10) of the printed version of the code is printed onto the item (180) with an original printing device. According to the methods, at least one picture (110) of the printed version of the code printed onto the item (180) is recorded with a low resolution camera at high speed during the production process, from which the barcode content (194) is decoded. Furthermore, irregularities in the picture (1 10) are analyzed by identifying at least one deviation (132, 134, 136, 138, 140, 142, 144) in the picture (110) with respect to the ideal image (150) and calculating a numerical value describing an individual imperfection profile (196) of the original printing device, wherein the calculating of the numerical value of the individual imperfection profile (196) depends on at least one unique feature inherently related to the original printing device, wherein the at least one unique feature is selected from at least one of a printing technology and a setting of the printing device. In the method for proving the authentication of the original item (180), the individual imperfection profile (196) is printed onto the item (180) and/or a database record (192) for the item (180) is generated. In the method for determining the authentication status of the suspect item (180), it is checked whether the code on the suspect item (180) has been printed with the original printing device by comparing the individual imperfection (196) profile of the suspect item (180) with the individual imperfection profile (196) of the original item (180), by which comparison the authentication status (172) of the suspect item (180) is determined. The method and apparatus (176) for determining the authentication status of the suspect item (180) are configured to be employed within industrial facilities for a fast and reliable authenticating of a plurality of suspect items (180). Moreover, the method and apparatus (176) may make use of existing recording devices (178) already used for recording print images with speeds and resolutions usually employed within industrial facilities.
