  • product elements is used here to reference individual units of a product such as tablets, pills, capsules, candy, bars or others, of pharmaceutical, food or chemical products, or electronic chips or integrated circuits or any other product that usually undergoes, for example along a commercial chain from the supplier to the user/recipient, packaging procedures which normally provide for grouping the individual elements of a same product or of assorted products according to specific criteria into "packages” of any type, such as a box, a blister, a cluster or others, or of individual packages into bundles (groups of a given number of individual packages), bundles into cartons, cartons into pallets.
  • Packaging can affect even a single unit of product which constitutes the "product element" which is presented to the user/recipient as a single packaged part which can be divided or not, such as for example a tablet of food, chemical, medical, electronic or any other industrialized product.
  • Counterfeiting relates both to the products proper and to their packaging.
  • the two main elements of such a known traceability system are the identification element, which is the pharmaceutical stamp, and a central data bank, where all the data from the readout of the stamps along the route of the drug, from the manufacturer to the distributor to the individual pharmacies and to disposal, must be gathered.
  • the identification element is a smart label, in which the printed portion would show the normal pharmaceutical stamp but would contain inside it a tag for RFID reading.
  • An anti-counterfeiting method which can be applied in the field cannot therefore be based on particular types of substances or on printing methods which are not approved for drugs or on complex shapes which set limits to the shape of the dose of medicine.
  • the reading means captures the image, which is read by a decoding software which reorients the image in the succession of light and dark shapes.
  • the basic components known for these uses are generally bar code printers, media for, and provided with, the bar code, code verification systems, reader and external database provided on a suitable computer.
  • the printer generates the label-medium which contains the symbols that identify the object to which it is applied.
  • the printers used can be laser or thermal printers, suitable to transfer the code onto the "medium", understood here, for example, as a label or layer of paper or synthetic material which can be applied to an object, such as a means for packaging, or can be applied to a group of product elements, or even as a region of the object itself.
  • the information contained in the bar code supports both a primary data structure, which comprises the name of the manufacturer, the name of the product and the level of packaging, as well as a structure for secondary data, such as one or more among the batch number, registration number and expiration date of the product. These secondary data can be used to check the position of the product within the supply chain to the point of use and to check and manage the expiration date.
  • Known readers of different types decode the information contained in the bar code and convert it into a signal which can be processed by a computer connected to the reader.
  • the final component is constituted by a database provided with the necessary software supported on a computer to provide an adequate interface between the reader and the software for managing the decoded information.
  • the effectiveness of the known anti-counterfeiting function is therefore linked to the complexity and uniqueness of the marker and to the difficulty in determining the codes that can allow to acquire information needed to replicate products which can be indistinguishable from genuine ones even in terms of marking.
  • the aim of the present invention is to eliminate the drawbacks noted above in known types of systems for identifying product elements by devising a new system, method and marking for identifying and validating individual product elements in a group of product elements, which are capable of providing the highest degree of reliability and non- counterfeitability by potential counterfeiters.
  • an object of the invention is to provide a new system, method and marking for identifying and validating individual product elements within a group of product elements which use devices and components which are commercially available and whose complexity and costs are low.

  • Another object of the invention is to provide the flexible and coordinate use of coding/marking devices and marking decoding/recognition devices which are independent of each other, in order to forbid unauthorized access to the system.
