Definitions

  • the present invention relates to a genuineness marking set comprising a plurality of authenticity markers, the use of the genuineness marking set for authenticating goods of any kind, a method for authenticating a product and a test method for checking the authenticity of the product.
  • the present invention is particularly applicable to the marking of bulk goods, i. H. Branded goods of any kind that the manufacturer wants to protect against imitation or whose imitation should be at least recognizable. Particularly suitable is the present invention for the identification of goods of any kind, which are due to the product only very briefly on the market, such as consumer goods with short shelf life.
  • counterfeiters are not only looking for value documents, but in general "branded goods", ie products for which a high price can be achieved if they come from a particular manufacturer.
  • the price can be justified by a particularly high quality, and the manufacturer suffers considerable damage if its products are mimicked by other providers in poor quality, not only by lost profits, but also by image loss, as the customer may not be aware that he has acquired a fake, but believes that the branded article is actually of inferior quality.
  • the object of the present invention is to provide a mark of authenticity for such goods, which provides an efficient counterfeit protection, but can do without the not freely obtainable "high-level” feature substances.
  • the labeling should also be as simple and easy be cheap.
  • the existing or missing authenticity should be able to be determined by common test methods.
  • the object is achieved by the authenticity marking set according to claim 1, the method for authenticating a product according to claim 8 and the test method for checking the authenticity of a product according to claim 12.
  • Embodiments of the invention are specified in the respective dependent claims.
  • the low-level features can be relatively easily identified by a counterfeiter, purchased on the market and used for counterfeiting.
  • the factor "time" is used for authenticity assurance.
  • the invention consists in using freely available feature substances in changing combinations which are unforeseeable for a counterfeiter, the changes occurring in a relatively rapid but chaotic and unforeseeable sequence for a counterfeiter.
  • a counterfeiter who sets out to analyze and imitate a mark has to reckon with the fact that his work is in vain at any time, since the imitated mark can be copied at the time he can imitate it. is outdated.
  • Such prospects have a dampening effect on forgery.
  • Two things are essential for the functioning of the type of authenticity marking according to the invention: Firstly, the manufacturer of the marked product or a designated labeling provider or authenticator must know which authenticity marking was made for this product in which period of time and must be able to identify a product at what time the marking was made. This is the only way he can determine whether the product bears the marking appropriate for the time of marking. This problem is solved according to the invention by some form of time indication on the product.
  • fluorescent substances and phosphors which are excitable in the UV range and fluoresce or phosphoresce in the visible range
  • fluorescent substances and phosphors which are excitable in the IR range and emit in the visible range or in the UV range
  • practically any combinations of excitation wavelength range and emission wavelength range are the UV-vis fluorescers which are excitable in the UV range and in the visible range fluorescences in different colors (typically red, orange, yellow, green).
  • Preference is given to inorganic luminescent substances with narrow emission lines. For example, a narrow emission line has europium.
  • UV-vis phosphors preferably inorganic phosphors, which are available with phosphorescence in several colors.
  • the phosphors are easily distinguishable from the fluorescers by their decay time after the excitation illumination is turned off.
  • luminescent substances are the so-called upconversion substances, which are likewise obtainable with luminescence in several colors (red, orange, yellow, green). They can be distinguished from the feature substance class of the UV-vis fluorescent substances and the UV-vis phosphors in that they can be excited by IR lasers for luminescence in the visible range.
  • Examples of the feature class of magnetic feature substances are hard ferrites such as barium and strontium ferrite, hard ferrites of the AlNiCo group, metal oxides, as used for magnetic information storage used, such as cobalt-containing iron (III) oxide, chromium dioxide or pure iron particles called. To distinguish magnetic material from each other, for example, remanence and coercive coercive force can be used.
  • thermochromatic dyes examples include the thermochromic mercury compounds Ag 2 HgJ 4 , Cu 2 HgJ 4 and Ti 2 HgJ 4 and thermochromatic sulfides and borates. The compounds change color when heated.
  • the greatest variation is offered by the luminescent substances.
  • the excitation spectra, the presence of double resonance, etc. can be checked here as distinguishing criteria.
  • a certain number of such feature substances are used to prepare a pool of fastness markers.
  • the authenticity markers are obtained by combining the feature substances with each other.
  • the pool is the larger, the more feature substances are used and in more diverse ways the feature substances may be combined. If, for example, three representatives each are used from the feature substance classes of the UV-vis fluorescers, the UV-vis phosphors, the upconversion substances and the magnetic pigments, this results in a total of 12 feature substances.
  • a pool of authenticity markers is prepared by combining three feature substances into one authenticity label, 220 different authenticity markers are obtained. Become additional Combinations of only two feature substances permitted, one receives in addition further 66 authenticity marking materials. If individual feature substances are also included in the pool, this will be increased by a further 12 authenticity labeling substances.
  • the pool becomes correspondingly smaller if the production criteria of the authenticity marking substances are made more restrictive: for example, combining three feature substances from the above 12 feature substances into one authenticity marking substance containing only one feature substance from each feature substance class yields a pool with 81 authenticity markers. Likewise, 81 authenticity markers are obtained by combining 4 feature substances from the same 12 feature substances, one representative from each feature class. From the pool of all conceivable combinations, a certain number of authenticity markers are selected and put together to form a mark of authenticity labeling that can be used to authenticate different products.
  • Feature substances within the meaning of the present invention are substances having a property suitable for labeling purposes, ie a property by means of which they can be clearly detected and identified. At least five different feature substances are preferably used, more preferably at least eight, even more preferably at least 12 different feature substances.
  • the feature substances may belong to the same or different classes of feature substances.
  • a feature class of substances is a group of substances that can be identified by the same detection method (UV-vis fluorescers for example by excitation in the UV range and emission in the visible range with a short decay time of the emission).
  • the authenticity marking substances used for the authenticity marking are formed.
  • the authenticity markers are usually a mixture of two or more different feature substances, preferably a mixture of two or three feature substances. However, it is also possible to use a single feature substance as an authenticity marking substance, or to mix more than three feature substances to form complex fastness identification substances.
  • the feature substances of a fastness marking substance may belong to the same or different classes of feature substances. As a rule, it is favorable if the feature substances belong to at least two different classes of feature substances.
  • a fastness marking set should contain at least three different fastness markers, preferably at least five different fastness markers.
  • the selection of the authenticity markers of a set from the pool of conceivable authenticity markers can be random. In general, however, you will at least make a certain pre-selection, d. H. one will be careful to have only authenticity markers in a set that are well identifiable.
  • Combinations of feature substances that are not well detectable side by side should not be included in the same fastness marker. Such combinations could, for example, be fluorescent materials which have strongly overlapping emission bands, or fluorescent substances and phosphors emitting in similar wavebands whose decay times are not very different.
  • An additional possibility of variation of the authenticity markers is to use not only the presence of a certain feature substance but also its concentration as a feature substance property. This makes counterfeiting even more difficult, but also makes identification more complex. In this case, mechanical testing methods for authentication are required, while in some cases, visual inspection may be sufficient, for example, in the case of combining UV-vis fluorescent with UV-vis phosphors.
  • the authenticity markers of a kit may be provided in different forms. Exemplary forms of provision are the Pure substances of the authenticity markers; Printing inks or printing inks containing the authenticity markers; Support materials to which the authenticity markers are applied or incorporated; or application-ready security elements.
  • the same set can be made in several forms of delivery to meet the possible applications as much as possible.
  • printing inks with different binders, suitable for printing on various substrates can be produced, or the authenticity markers can be applied to substrates made of paper, plastic or textile.
  • security elements can be produced in ready-to-use form, for example labels, tear-open threads for packaging, transfer elements, patches for textiles, etc.
  • the authenticity marking materials can be located on or in an adhesive.
  • each manufacturer who wants to secure his products in the manner according to the invention is able to compile their own authenticity labeling sets.
  • the manufacturers concerned it is more advantageous and simpler for the manufacturers concerned to transfer the product assurance to a professional labeling provider or authenticator.
  • the customer ie the manufacturer of the product to be secured, receives the authenticity marking materials in the form desired by the customer, for example as pure substances or in ready-to-use form as a label or the like.
  • Several customers can use the same authenticity labeling set. It is in no way disturbing when a large number of different products from different manufacturers or even the same manufacturer using the same authenticity labeling set is characterized.
  • Authentication takes place through a combination of three criteria: product - authenticity marking feature - period of application of the authenticity marking feature.
  • product is assigned a specific type of authenticity marking set, that the authenticity designating materials of a set are successively used in a specific order to identify the product, and that each authenticity marking substance is only used for a certain period of use. It is essential that for a counterfeiter neither the order of use of the individual authenticity marking materials, nor the beginning and end of their application periods are foreseeable in any way.
  • the basis of the security concept according to the invention is therefore the chaotic change between different labeling substances and the duration of their application periods.
  • the order in which the authenticity markers of a kit are used for product assurance and the beginning and end of the period of application of a mark of authenticity can be determined intentionally or randomly (by random generator). In case of a random definition, certain specifications can or must be made. Thus, no authenticity marking substance should be used twice in succession, and the periods of use of successive authenticity marking materials must be consecutive. It is also convenient to set guidelines for the duration of the application periods to exclude extremely short and extremely long application periods. Meaningful periods are, depending on the product, in the range of days or weeks, in exceptional cases u. U. also in the range of months.
  • the authenticity marking according to the invention preferably takes place in such a way that a marking provider produces authenticity marking sets, and at the request of a customer for a genuineness marking set to be supplied, determine an order of use and associated application periods of the genuineness marking materials of the set.
  • an identification table is created, which correlates the product with the used authenticity markers and their respective application periods.
  • the setpoint values of the feature substance properties of the individual authenticity marking materials which are to be expected in the case of an authenticity check for a genuine product are preferably also recorded in the table.
  • the authenticating marking set is delivered to the customer, together with a precise instruction as to when to use which authenticity marking material.
  • the authenticity labeling materials in the required amount can also be delivered in each case only when a change of the authenticity labeling materials is imminent. In this way, mistakes of the customer can be largely avoided.
  • Sensible overall use periods of a kit may vary widely, depending on the product, the number of authenticating markers of the kit, the length of application of the authentication markers, and the desired level of safety. Typical periods are from a few weeks to a few years.
  • Every authenticity marking only makes sense if the authenticity can also be checked beyond doubt.
  • verifiability requires, first and foremost, that it be possible to establish beyond doubt which authenticity marking substance must be present on the product concerned, provided that it is genuine. Therefore, not only the authenticity marking substance itself is affixed to the product, but also a time indication indicating the date of the marking, or indicating the date of the marking or allowing conclusions to be drawn for a specific period of time. For example, a date of manufacture of the product or an expiration date of the product may be printed. If it is known at the same time that the marking takes place on the day of manufacture, or that the shelf life is, for example, seven days, this clearly identifies the identification date.
  • the date may be attached to the product in invisible or encrypted form.
  • thermochromic dyes which are colorless at room temperature but become visible on heating or colorless
  • electrically conductive polymers such as, for example, polyethylene dioxythiophene / polystyrene sulfonate (PEDT / PSS) are recommended for an invisible attachment.
  • PET / PSS polyethylene dioxythiophene / polystyrene sulfonate
  • each application period could be assigned a longer sequence of numbers, which varies from article to article but is generated according to specific criteria.
  • a criterion could be, for example, that at any point in the sequence of digits, the digits 5 and 8 occur in succession and the next following third digit is a 1.
  • a counterfeiter does not know the criterion according to which the digit sequence is generated. If he recognizes the connection between authenticity marking and number sequence, he must therefore at least each product that he equips with the identified authenticity mark with the identical Digit sequence that has the analyzed real product equip. If a dealer finds several products with the same number of digits, this indicates a counterfeit.
  • Another alternative way of attaching the date in a form that is not associated with a date is to use an individual serial number with fixed correlation to the date instead of a date.
  • the authenticity mark can be affixed to the product itself or to its packaging.
  • the type of attachment is largely arbitrary, as long as it is compatible with the labeled materials. The same applies to the authenticity marking materials used. It should be understood that fluorescent materials excited by X-radiation should not be used in labels for adhering to film cartridges, or that magnetic particles are less suitable for marking electronic recording media.
  • the feature substances of a fastness marking substance are not applied in a mixed form, that is, forcibly at the same location of a product or its packaging, but provided at various locations.
  • This is a good way to increase the security level of the authenticity marking, especially for larger articles or packaging.
  • authenticity labeling features in the form of fluorescent substances could be applied in a clearly visible manner at one point of the packaging, while at another location, for example on the inside of the packaging, an additional authenticity marking in the form of magnetic pigments is present.
  • goods such as designer clothes, which typically carry multiple patches or patches, they can be used to apply a mark of authenticity at different locations.
  • the authentication of a counterfeit product may be performed by the person who owns the identification table for the corresponding product. This may be the manufacturer of the product, but it will preferably be the label provider who has assembled the authentication tag set.
  • the identification table is highly secrecy-sensitive, because whoever owns this table is also able to tag fake products with real labels. Therefore it is safer if identification tables are not in reach the relatively insecure area of manufacturers, but remain in the well-secured area of a authenticity labeling provider. This ensures that authenticity labeling materials stolen from a manufacturer can not be used.
  • Authenticity testing is performed in the following manner: Counterfeit products are sent to the marketer, or, less preferably, authenticated by the manufacturer. For each product, the identification table prepared in advance for the corresponding product, which is advantageously stored electronically, is retrieved. The date of labeling is determined on the product. This can be done simply by reading the appropriate date. In the case of a covert or coded date, the identification table is consulted to determine where, and in what form, the date for the corresponding product. If the product to be tested does not carry a date or if the date is not encoded in the correct form, the product is already exposed as a counterfeit. Otherwise, the identification table is taken as to which authenticity label was used on the relevant date for the product to be tested.
  • the marking is irradiated with UV radiation and the emission wavelength and decay time of the emitted radiation are measured.
  • the measured values are compared with the nominal values to be expected according to the identification table. If there are deviations between the measured actual values and the expected target values, the product is forged. In the case of a match, however, it can be assumed that it is a genuine product.
  • the authentication is typically a machine test. In the case of very simple authenticity labeling sets u. Also, a visual inspection may be made, for example, when in each case a UV-vis fluorescent substance and an upconversion substance, which is also emitted in the visible range but is excited by IR light, are combined. The test criterion is then whether the visible emission color matches the expected color.
  • a machine test can be performed much more accurately. It also allows the use of a much larger number of feature substances, namely feature substances with properties that are inaccessible to visual inspection, such as magnetism, electrical conductivity, emission in wavelength ranges other than visible light.
  • concentration of the feature substances in the authenticity markers can be used as an additional criterion, ie. H. a mark of authenticity can u. U. contain authenticity markers that are composed of the same feature substances, but the proportions of the individual feature substances are different on the relevant authenticity markers.
  • the authenticity marking set (EK set) shown is based on four feature substances (MS1, MS2, MS3, MS4).
  • MS1 is, for example, a UV-vis fluorescent substance, MS2 an upconversion substance, MS3 a soft magnetic feature substance and MS4 a hard magnetic feature substance.
  • the feature substances are combined in different ways into authenticity markers (EKS).
  • EKS authenticity markers
  • the "X" respectively designate the feature substances present in a fastness marker, ie EKS1 contains MS1, MS2 and MS3.
  • the authenticity markers of the set in the case shown by way of example five authenticity markers, are now used in the procedure according to the invention for authenticating various products.
  • a crucial safety aspect of the present invention resides in the chaotic and unpredictable changeover between substances used for authenticity labeling.
  • Fig. 2 is given for five products (P1, P2, P3, P4, P5) as their authenticity labeling varies over time.
  • the product P1 is first marked with the authenticity marking substance EKS1 for a certain period of time, followed by EKS4, EKS3 and EKS2.
  • EKS2 is used comparatively the longest. It follows very short application periods of EKS1 and EKS3, then again a slightly longer period of EKS4 and finally a period in which is marked with EKS3.
  • a new application cycle of the same set may follow (naturally varying the order of the authentication markers and the duration of their application periods), or a completely different set can be used for labeling.
  • the set used first may also be varied slightly, for example, by combining the feature substances into authenticity markers in another way or by adding an additional feature substance or replacing one of the previous feature substances with another feature substance. It is obvious that even with few feature substances as starting substances numerous possibilities of variation arise.
  • Fig. 2 also shows other products P2 to P5 or the order in which the products with the various authenticity markers of the in Fig. 1 and for what period they are each marked with each authenticity marking material.
  • P1 and P4 much more frequent changes occur between the various authenticity markers than, for example, with the products P3 and P5.
  • the type of product to be labeled was taken into account.
  • P1 and P4 could be designer clothing and a CD, that is, products that have been on the market for at least several months in their unaltered form and without a sell-by date. At the same time a concealed or encrypted date is recommended.
  • P2 could be a perfume, P3 a cosmetic, and P5 and a food.
  • Products with a short shelf-life, such as food, are particularly suitable for the authenticity marking according to the invention.
  • the type of authenticity marking according to the invention can therefore be adapted in an ideal manner to the product to be marked and the desired level of security.
