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.
- the present invention is particularly suitable 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 more generally "branded goods", ie products for which a high price can be obtained, provided that they come from a particular manufacturer.
- the price can be justified by a particularly high quality, and the Producers suffer significant damage if their products are mimicked by other suppliers of inferior quality, not only by lost profits, but also by image loss, since the customer may not be aware that he has acquired a fake, but is of the opinion 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 offers an efficient counterfeit protection, but can do without the not freely obtainable "high-level" feature substances 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 use of the authenticity labeling set according to claim 16, the method for authenticating a product according to claim 18 and the test method for checking the authenticity of a product according to claim 25.
- Embodiments of the invention are disclosed in the respective dependent claims.
- feature substances which are freely available on the market so-called “low-level” feature substances, are preferably used for the authenticity marking
- the high-level feature substances used for authenticating value documents can also be used, but this is not necessary.
- 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 in the authenticity assurance according to the invention
- the invention consists in using freely available feature substances in changing combinations which are unforeseeable for a counterfeiter, the changes being relatively faster but more chaotic and
- Such prospects have a dampening effect on forgery.
- the fact that the type of authenticity marking according to the invention functions is preceded by two things.
- the manufacturer of the marked product or one of his designated marketer or authenticator has to know which authenticity mark has been used for this product in which period of time, and he has to work on a product determine when the labeling took place. 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.
- typically freely available and available substances are used for authenticity labeling.
- substances from the classes of feature substances of fluorescent substances, phosphors, hard magnetic and soft magnetic feature substances, electrically conductive metallic and nonmetallic materials, thermochromic feature substances, upconversion substances, etc. can be used.
- the luminescent substances can be subdivided further according to the Wavelength ranges in which they are excitable, or in which they emit.
- fluorescent substances and phosphors which are excitable in the UV range and fluoresce or phosphoresce in the visible range fluorescers and phosphors which are excitable in the IR range and emit in the visible range or in the UV range, and others, virtually any combination of excitation wavelength range and emission wavelength range.
- UV-vis fluorescers which are excitable in the UV range and in the visible range fluorescences in different colors (typically red, orange, yellow, green).
- 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 substance class of the 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.
- 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.
- cobalt-containing iron (III) oxide such as cobalt-containing iron (III) oxide, chromium dioxide or pure iron particles called.
- remanence magnetization and coercive force can be used.
- thermochromatic dyes are the thermochromic mercury compounds Ag2Hgj4, Cu2Hgj4 and Ti2Hgj4 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 combinations of the feature substances.
- 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 fluorescent substances, the UV-vis phosphors, the upconversion substances and the magnetic pigments, this results in a total of 12 feature substances. If a pool of authenticity markers is prepared in such a way that three feature substances are combined to form a fastness marker, 220 different authenticity markers are obtained. If additional Lich combinations of only two feature substances approved, one obtains an additional 66 authenticity markers. If individual feature substances are 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 markers are made more restrictive: for example, combining three feature substances from the above 12 feature substances into a fastness marker containing only one feature substance from each feature class gives a pool with 81 fastness 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 marking substances are selected and put together to form an authenticity labeling set which 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 substance class is a group of substances that can be identified by the same detection method (UV vis- Fluorescent substances, for example by excitation in the UV range and emission in the visible range with a short decay time of the emission).
- the feature substances preferably belong to at least two different classes of detergent, more preferably at least three different classes of ingredients, and in general it is all the more preferable the more different classes of feature substances are included. However, under certain conditions, for example when particularly simple authenticity markers are desired, it may also be advantageous to use only one or two classes of feature classes.
- the authenticity marking substances 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 authenticity coding substance, or to mix more than three feature substances into complex authenticity labeling 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.
- each authenticity marking substance consists of three different feature substances 7 of which at least one is a UV-vis fluorescent substance, or
- each authenticity marking substance consists of two or three different feature substances, at least one of which is a UV-vis fluorescent substance, and at least one is a UV-vis phosphor, or
- each authenticity label consists of one, two or three feature substances, the feature substances (in the case of more than one feature substance) belonging to different classes of feature classes, or
- Each authenticity marking substance consists of at least three different feature substances, or ...
- a fastness marking set should contain at least three different authenticity markers, preferably at least five different authenticity markers.
- the selection of the authenticity labeling substances of a set from the pool of the conceivable authenticity marking substance e 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.
- 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.
- the authenticity is ensured by a combination of three criteria: product ⁇ authenticity identification feature ⁇ period of application of the authenticity marking feature.
- product is assigned a specific type of authenticity label, that the authenticity labels of a kit are used successively in a specific order to identify the product, and that each authenticity label 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 substance e, 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 fastness 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 manufactures authenticity labeling sets. and, at the request of a customer for a genuineness identifier set to be supplied, establish an application order and associated application timeframes of the kit's authentication markers. At the same time, an identification table is created, which correlates the product with the authenticity markers used 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. Then, the authentication kit is delivered to the customer, together with a precise instruction as to when to use which authentication marking substance. Alternatively, 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.
- 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.
- a date of manufacture of the product or an expiry 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. Such an obvious date is only recommended for products with a short shelf-life. With a simultaneous rapid and chaotic change of the authenticity markers, it is not detrimental if a counterfeiter succeeds in recognizing the relationship between the date and the authenticity marking substance and also identifying the authenticity marking substance.
- 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 / polystyrenesulfonate (PEDT / PSS)
- PET / PSS polyethylene dioxythiophene / polystyrenesulfonate
- 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 the authenticity marking and the number sequence, he must therefore at least identify each product which he equips with the identified authenticity mark with the identical equip the sequence of digits that the analyzed genuine product has. 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 not related to 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.
- 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 labeling electronic recording media.
- the feature substances of a fastness marking substance are not applied in mixed form, that is to say compulsorily at the same point of a product or its packaging, but are provided at different 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, there is additionally an authenticity marking in the form of magnetic pigments.
- authenticity markings in the form of magnetic pigments For 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 preferably it will be the marketer who has assembled the mark of authenticity designation.
- 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 rather, they remain in the well-secured area of an authenticity labeling provider ⁇ This ensures that even authenticity labeling materials developed for 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, visual inspection may be performed, for example, when each UV-vis fluorescent and upconversion material that is also emitted in the visible range but is excited by IR light is 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 labeling substances can be used as an additional criterion.
- H. a certificate of authenticity can be u.
- U. contain authenticity markers which are composed of the same feature substances, but the proportions by volume of the individual feature substances are different on the relevant authenticity markers.
- FIG. 1 shows an inventive authenticity marking set
- 2 shows the time course of the authenticity marking according to the invention of various products with the authenticity marking set according to FIG. 1.
- the authenticity marking set (EK set) shown in FIG. 1 is based on four feature substances (MS1, MS2, MS3, MS4).
- MSl 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 labeling substances (EKS). In the present case, the requirement for the combination is that an ECS must be a subset of one or two or three feature substances out of the total of four feature substances, with no restrictions on the class of feature substances.
- EKS1 contains MS1, MS2, and MS3.
- kit's authentication markers five authenticity markers in the exemplary case, are now used in the inventive method of 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 (Pl, P2, P3, P4, P5), as their authenticity marking varies over time.
- the product P1 is first marked with the authenticity label 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 EKSl and EKS3, then again a slightly longer period of EKS4 and finally a period in which EKS3 is identified;
- a new application cycle of the same set may follow (naturally varying the order of the authenticity markers and the duration of their application periods), or a completely different set can be used for identification drawing.
- 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 and the order in which the products are labeled with the various fastness markers of the set shown in Fig. 1 and for what period of time they are each labeled with each fastness marker.
- Pl 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.
- Pl 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 product and P5 and a food product with a short shelf life, such as food, are particularly suitable for the authenticity marking of the invention.
- one and the same authenticity marking set can be used for a wide variety of products, even from different manufacturers.
- the achievable level of security can be adapted to a certain extent to the needs of the customer.
- the degree of recoverable security against counterfeiting is determined by
- Feature-related criteria the more complex a genuineness labeling set, ie. H. the more authenticity markers it contains, the greater the number of starting feature substances, the more "exotic" the individual feature substances, and the more feature substances each make up a mark of authenticity, the more certain is the labeling;
- Time-related criteria The shorter the periods of application of the respective authenticity marking materials and the more chaotic the change takes place, the safer the marking;
- the present invention is particularly suitable for products which are only on the market for a short time due to the product, for example consumer goods with a short shelf-life.
- a short shelf life in combination with a chaotic change between authenticity markers and short application times of the authenticity markers guarantee a high level of safety.
- Very simple authenticity labeling sets can be used here;
- Time-related Criteria The present invention necessarily requires some form of date indication on the product or its packaging in order for a unique product-authenticity-label-application period designation to be made. Hidden, invisible or encrypted time information increases security.
- 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.
