Definitions

  • the invention relates to a system for checking the authenticity and / or completeness of goods as well as a method for product security of goods.
  • Another way of securing the product is to secure the packaging, not the product itself.
  • tear threads for packaging with luminescent substances EP 0 901 970 A2
  • tax stamps as are customary, for example, in the case of cigarettes or alcohols, with holograms.
  • this type of protection has the disadvantage that it can be determined whether the packaging is authentic, but it is not possible to say with certainty whether the products contained in the packaging are actually authentic.
  • the invention is therefore based on the object of developing a product assurance system and a method for product assurance with which products can be labeled in a cost-effective and economical manner and which at the same time makes it possible to determine whether these products are of authentic origin.
  • the system for checking the authenticity and / or completeness of goods consists of at least one product and an associated packaging, the product bearing a first identification and the packaging a second identification.
  • the first and second labeling are in a predetermined relationship to one another, so that by checking the first and second labeling, conclusions can be drawn as to whether they belong together and, if necessary, the authenticity of the product and packaging.
  • the system consists of at least a first product and a second product, the first product carrying a first label and the second product a second label.
  • the first and second identification have a predetermined relationship to one another, so that by checking the first and second identification, conclusions can be drawn as to whether the two products belong together and, if appropriate, are genuine.
  • the system consists of a product which is composed of different individual parts, the individual parts each bearing the same or different, in particular individual, first identification and at least one of these individual parts additionally or exclusively bearing a second identification.
  • first or first markings and the second markings are in a predetermined relationship to one another, so that by checking the first and second markings, conclusions can be drawn about the togetherness and, if appropriate, the authenticity of the product.
  • the system can also consist of several products or a product of several individual parts and a data carrier assigned to these products, the products or the individual parts of the one product each being provided with a first identification and the data carrier bearing a second identification.
  • the first and second identification have a predetermined relationship to one another, so that by checking the first and second identification, conclusions can be drawn about the belonging together and, if appropriate, the authenticity of the products or individual parts.
  • the product security system according to the invention has the advantage that very simple, inexpensive methods can be used for the production of the first and second labeling, since the security aspect lies in the correlation between the two labels. The given relationship should therefore be as difficult to understand as possible and not recognizable to counterfeiters.
  • the second identification is therefore preferably calculated using cryptographic methods from the first identification or parts of the first identification.
  • the security of the Systems can be further enhanced by using cryptographic techniques that use secret keys that are not known to the general public. Additional information can also be taken into account when calculating the second identification.
  • date information and / or information relating to the manufacturing site of the product in question can be taken into account when calculating the second identification. In this way, the age and / or the origin of the product can be safely monitored at the same time during the completeness check. Taking this additional information into account also increases the security against counterfeiting.
  • the expiry date or the date information can also directly represent the first label.
  • the type or method with which the marking is generated can contribute to the security of the system. Because the more inconspicuous the labeling, ie the more difficult it is to identify the labeling as such, the less there is a risk that a potential counterfeiter will try to imitate the labeling.
  • the first label therefore forms an individual parameter inherent in the product. This means that a special, characteristic parameter of the product itself, such as a specific pressure tolerance, a specific dimension or a specific physical, chemical or optical property, is determined and used as the first identifier for the calculation of the second identifier. If the product is, for example, a paper product, the cloudiness of the paper can be evaluated at a specific point and used as an individual parameter. The evaluation of angular relationships between Print images or markers positioned at random to one another are possible.
  • the second identification can be applied to the packaging in such a way that it is not visually recognizable, e.g. by printing it on using a visually invisible luminescent substance or recording it in a storage medium provided on or in the packaging.
  • first and second labeling are described below.
  • the type of labeling that is sensibly used in an individual case depends on the goods to be secured and the desired security standard.
  • the first marking does not consist of an individual parameter of the product and is additionally applied to the product, it can be provided as plain text information or in the form of a coding, such as a binary coding, a one- or two-dimensional bar code or another, under certain circumstances random geometric pattern. It can represent a serial number, the date of manufacture or expiry of a product, a random number, pseudo-random number or other information.
  • the label can also be defined at a specific point on the product or, possibly under several circumstances, distributed randomly on the product. The application of a magnetic strip is also conceivable.
  • the first identification can be printed using any printing method, with certain printing methods having a higher level of counterfeiting offer security, such as intaglio printing, which creates a tangible, relief-like print image.
  • printing inks also influences the degree of protection against forgery of the marking.
  • feature substances with at least one special visual and / or machine-checkable physical property can be added to a printing ink.
  • These can be, for example, electrically conductive, magnetic, luminescent or optically variable properties such as those shown by liquid crystal pigments or interference layer pigments.
  • These can be luminescent substances that are both excitable and emit in the invisible spectral range.
  • the luminescent label In order to ensure that the luminescent label is as easy to read as possible, it may also be useful to underlay the background in the area of the label with a luminescent substance and to label the label itself with e.g. black, non-luminescent printing ink.
  • a luminescent substance e.g. black, non-luminescent printing ink.
  • the entire area is illuminated with excitation radiation. Since only the luminescent background that is not covered by the marking emits radiation, the marking emerges as dark information that strongly contrasts with the luminescent environment.
  • the marking can be created by punching, embossing or material removal.
  • the material can be removed by means of a laser, for example.
  • one or more layers of color can be arranged one above the other, which can be removed in a targeted manner, so that a single-color or multi-color identification that contrasts with the surroundings is created.
  • the laser can also be used to create hole coding or perforation.
  • the marking can be embedded in a perforated environment by varying the hole diameter and / or spacing as visually recognizable information.
  • the marking can also be shown by varying the hole shape or phase shift of two rows of holes.
  • a regular perforation can also be provided so that no visually recognizable information is created.
  • a certain parameter of the perforation e.g. the hole diameter and / or hole spacing.
  • the laser can also be used directly for labeling the product.
  • a laser for example a CO2 or Nd: Y AG laser
  • the laser beam is controlled electronically using suitable software.
  • the laser radiation creates an irreversible color change in the product.
  • the material usually blackens. If the product itself cannot be labeled or can only be inadequately inscribed with a laser, the product can be printed with at least in the area of the marking with a varnish which contains laser radiation absorbing additives which ensure that the varnish in the area of a blackening occurs. With a correspondingly high laser intensity, the product material is also blackened, so that a manipulation attempt in the area of the paint or a scratching off of the paint can be easily recognized.
  • the marking can also be generated by means of optical diffraction structures.
  • special diffraction gratings or groups of diffraction gratings can serve as identification.
  • Certain parameters of a diffraction structure on the product, such as the grating spacing, can also serve as the first identifier.
  • the first label can also be composed of several individual labels which have been produced using various of the methods described above. In addition, other methods for generating identifications, which are not mentioned here, can also be used.
  • the second identification can also be generated according to one of the methods explained above in connection with the first identification.
  • the packaging material can be provided with a storage medium in which the second identification is stored. This can be, for example, a chip, a magnetic memory or an optical memory.
  • the first and second identification can also be applied to a label which is applied to the respective product and / or the respective packaging. It is also possible to prepare the first and second labeling on a transfer material. In this case, the labels are transferred from the carrier tape of the transfer material to the product or packaging. This procedure is Particularly useful if diffractive structures are used to generate the markings or parts of the markings.
  • the step of generating the first label is preferably integrated into the manufacturing process of the product.
  • a manufacturing stage is preferably selected in which a fixed assignment between the goods and the packaging is already possible, so that it is not necessary to read the first identification again later. This presupposes that the first identification can be called up in a corresponding data memory and stored in correlation to the product.
  • the packaging can also be provided with the second label before the final merging of goods and packaging, once it is clear which products are assigned to it.
  • the first labels must be read from the products and encrypted shortly before or already in the packaging.
  • the second label is then generated on the packaging.
  • the first label on the product is read.
  • a verification code is then calculated from the first identification using the same encryption method that was used to calculate the second identification, and this verification code code compared with the second identification that was also read. If the test code and the second identification match, it can be concluded from this that the correct number of authentic products is contained in the packaging.
  • the second label is decrypted and the test label obtained from it is compared with the associated first label on the respective products.
  • This procedure is used if a public key procedure is used to encrypt the first identifier. This is because a secret key known only to the issuing body is used for the process of encrypting the first identifier. A publicly known key can be used for the decryption. In this way, the secret key does not have to be communicated to the corresponding test centers.
  • an authenticity check of the product and the packaging can take place before or after the completeness check. If, for example, both the first and the second identification are shown by means of a luminescent substance, it can be determined in a first test step whether the product and the packaging show luminescence in the correct wavelength range. If not, the test can already be stopped at this point because the product or the packaging is a counterfeit. However, if the product and packaging show the correct luminescence, the information content of the first and second identification is determined and the corresponding relationship between the first and second identification is checked.
