In the past three NIP conferences, the author have presented novel techniques for embedding security information into the Variable Data Printing (VDP) for labels, documents and packaging. Recently, one have discovered that fundamental assumptions in other fields - Error Correcting Code (ECC), classification and the use of color, for three examples - are not necessarily valid when functional security is the goal of the printing. It will be shown herein that the assumptions behind default ECC do not hold for 2D or color 2D barcodes with mobile image capture. Alternatives to ECC are suggested. When security-related tasks are the end goals of the printing and imaging, the deployment optimization for image classification is fundamentally altered.
