Authentication Feature In A Barcode
Patent No. EP3311336 (titled "Authentication Feature In A Barcode") was filed by Hicof on Jun 15, 2016. The application was issued on Feb 1, 2023.
Patent Summary
A method for product serialization introduces an authentication feature into a barcode via printing modifications. A central database provides print batch data comprising sequential serial codes and individual security rationales. This data is transmitted to a variable-data printing device to produce a modified barcode using a specific serial code and its assigned security rationale. The barcode is printed at a resolution preventing identical pixel counts per module, utilizing at least two module types with different pixel assignments. The distribution of these modules is determined by the combination of the serial code and security rationale, covering position information for specific modules, columns, or rows. Additionally, this combination is adapted to alter at least one padding code word within the modified barcode.
