Definitions

  • the present invention relates to a security system for securing an article against manipulation, comprising a sealing label having at least an adhesive layer and a cover layer, wherein the sealing label is attachable to an object to be secured by means of the adhesive layer and has at least one securing means for signaling a manipulative engagement.
  • the present invention further relates to a housing assembly having a housing as a particularly preferred object to be secured and a corresponding security system and a method for producing a corresponding security system.
  • a seal can make the authenticity comprehensible and make forgery of the document difficult or even impossible.
  • it is customary to affix a seal on a collision edge of adjacent housing parts to safety-critical parts in order to prevent unnoticed opening.
  • the seal must be applied and how to handle it.
  • the SMGW installer has to check the integrity of the seal according to the Technical Guideline BSI TR 03109-1, chapter 6.2, if the seal is in an invisible area after installation of the SMGW (lines 2590 to 2592 of version 1.0 of Technical Guideline of 18 March 2013).
  • the Applicant has developed a housing in which the label seal is attached to a front side of the housing and remains visible even when mounted in front of a sealed Berstoffschutzabdeckung a control box.
  • a single seal label identifies any unauthorized opening of the housing.
  • Such a housing is in the Fig. 1 and 2 is shown and is in the DE 10 2014 220 169 A1 described in detail.
  • Seal etiquettes include various counterfeit security features that can not be reproduced by common means such as a color printer. These include, for example, UV or heat-reactive materials, fine structures or holograms, resulting in a different appearance of the seal depending on the viewing angle, the lighting and / or the temperature. Tamper evident features may be formed, for example, by a remaining residue, a change in the label background, a disintegration into individual parts or a deformation of the seal label during manipulation attempts.
  • Seal labels usually consist of at least two layers: an adhesive layer and a cover layer with tamper-proof contents.
  • a manipulation attempt is to activate manipulation security features by, for example, detaching the at least two layers from one another.
  • the total thickness of such seal etiquette is usually in the range between 0.01 mm and 0.04 mm.
  • the layer thicknesses are designed to ensure a non-destructive release of the seal label from the carrier film during application, and influence the severity of the protectable manipulation.
  • the thinner the seal label the more difficult manipulation attempts become, since it tears, for example, with little mechanical stress during attempted detachment.
  • thicker seal labels are easier to handle because the risk of damage during application decreases with increasing thickness. Therefore, the design of the overall thickness of the seal label is a compromise between handling during application and the degree of protection to be achieved.
  • One of the main attempts at manipulation is by heat, for example by means of a hot air blower.
  • heat for example by means of a hot air blower.
  • it is attempted to make the adhesive layer sufficiently soft, so that a removal of the seal label and subsequent reattachment is possible. Due to the process, a higher adhesion between the label layers is to be expected than to the device substrate.
  • manipulative heat input it is with thicker labels, e.g. 0.04 mm, easier than thin labels, e.g. 0.01 mm, undamaged by an object to solve.
  • thin labels the introduction of heat often leads to a deformation of the film layer, so that the label is destroyed. Therefore, it is useful for a safeguard against manipulation under heat to use thinner label.
  • thicker labels are much easier to apply in an automated production process on the object to be protected.
  • Machine application of thin labels is currently extremely difficult or impossible to realize. Therefore, when attaching to a machine, thicker labels must be used. If thin labels are to be used, only a manual application remains. For large quantities (for example, 100,000 pieces per year and more), however, it is a major cost factor to have manual work in the manufacturing process. Thin labels can only be used for small batches.
  • the present invention has for its object to design a safety system of the type mentioned and further, that a reliable securing an object against manipulation and / or forgery is possible, the backup system should be produced in an automatic process.
  • a corresponding housing arrangement and a method for producing the security system should be specified.
  • the above object is solved by the features of claim 1.
  • the security system in question is characterized by a securing structure that partially covers the seal label and is at least partially connected to the seal label, wherein the seal label and the securing structure form an irregular overall structure, so that in a manipulative intervention triggering one or more of at least a securing means and / or destroying the securing structure is favored.
  • the above object is achieved by the features of claim 13.
  • the features of claim 15 solve the above problem.
  • an improvement in the protection against tampering can be achieved by additionally applying a securing structure to the sealing label.
  • This securing structure covers the seal label partially and is connected at least in some areas with the seal label.
  • the security structure significantly changes the overall properties of the security system consisting of the seal label and the security structure, resulting in an irregular overall structure, thus providing additional protection for the seal label.
  • the security system will behave significantly differently than in areas where no portions of the security structure are on the seal label. In this case, it is sufficient if the securing structure has a thickness in the order of magnitude of the sealing label.
  • a rather thin securing structure is already sufficient to effectively prevent manipulation, for example via heating of the adhesive of the adhesive layer.
  • the irregular overall structure of the sealing label and the securing structure results in the fact that, in the case of a manipulative intervention, one or more of the at least one securing means of the sealing label is triggered and / or the securing structure is destroyed by the manipulative intervention. In both cases, the manipulative intervention is very clear.
  • the security structure can easily be produced in an automated production process on the seal label.
  • the security structure can be produced by means of a printing process, by means of extrusion or by spraying a UV-curing material.
  • a printing method for example, the PrintoLUX method can be used, in which a water-soluble ink is printed and then cured in an oven. A description of such a method is in DE 10 2008 034 839 A1 disclosed.
  • An extrusion job is similar to 3D printing where material is applied three-dimensionally to a surface and fused to the surface.
  • a UV-curable material that could be sprayed on as a fuse structure may be formed by a UV-curing adhesive. Corresponding methods and materials are well known in the art.
  • the security structure provides additional assurance of the seal label, a thicker, machine-applicable seal label can be used. Since the securing structure can also be designed to be able to be applied by a machine, a security system is created which can be attached to an object to be secured in an automatic production process and at the same time offers effective and high protection against tampering. This avoids the need for manual labor in the manufacturing process.
  • the security system is also suitable for securing against counterfeiting, if one of the security devices additionally offers protection against counterfeiting. Since manipulation can be prevented or at least made considerably more difficult by the securing structure, an anti-counterfeiting feature indicates a high probability that the secured object is not forged.
  • the at least one securing means which has the sealing label for signaling a manipulative intervention, can be formed in various ways.
  • the securing means is formed by a predetermined breaking point, deformation upon introduction of heat, change of the label background in case of attempted lowering of the label, disintegration into individual parts, a recognizable residue after removal of the sealing label or the like.
  • Corresponding manipulation security features are well known in practice. The present invention does not impose any appreciable limitations on the usable securing means.
  • the label seal may include anti-counterfeiting features such as UV or heat reactive materials, fine structures, holograms or metallized surfaces.
  • the present invention does not have any essential requirements. It is important that the seal label is sufficiently thin so that in a manipulative procedure, the seal label tears or another securing means is activated or triggered. All the total thicknesses that meet these requirements can thus be used in principle in connection with the teaching of the invention. Preferably, however, the total thickness of the seal label is in the range of 30 microns to 50 microns, with a most preferred total thickness is about 40 microns.
  • the object to be secured may be formed by a document, an area of a housing assembly, a complete device, a vehicle, a container or the like. It is only essential that the surface of the object to be secured is suitable for sufficient adhesion of the seal label to the object to be secured. This is for example given when the surface is sufficiently smooth and the adhesive layer adheres well to the material of the object to be secured. However, this requirement is sufficiently simple to meet. In a very particularly preferred embodiment, however, the object to be secured is formed by a housing in which the electronics of a SmartMeter gateway is very particularly preferably arranged.
  • the sealing label can in principle be formed by a conventional, known from the prior art seal label, which consists of at least two layers, in particular an adhesive layer and a cover layer. It is in principle irrelevant from which materials the cover layer and the adhesive layer and whether more layers are present.
  • seal labels with a cover layer made of a plastic film, of metal, such as aluminum, or of paper, for example would be conceivable.
  • a security structure can be partially overlapping on the seal label attached and a connection between the seal label and the securing structure can be produced. However, this requirement is very easy to meet if the material of the security structure is suitably adapted to the selected sealing label.
  • the mechanical properties of the sealing label and the securing structure differ from each other.
  • the various mechanical properties can be different. It is conceivable, for example, a different coefficient of thermal expansion, whereby at a heat input, for example by means of Schu Kunststoffgebläse, the securing structure undergoes a greater thermal expansion than the sealing label, so that the securing structure tears the underlying seal label. It is also conceivable that the sealing label is formed bendable while the securing structure is brittle. In this way, for example, in the case of an underlayment by means of a razor blade, the securing structure can jump, as a result of which, for example, the optical properties of the securing structure are changed.
  • the sealing label and the securing structure have a different bending stiffness from each other.
  • the sealing label can be made relatively flexible, while the securing structure is formed of a rigid material.
  • an underlapping of the seal label for example by means of a razor blade, causes parts with safety structure raised differently than parts without safety structure. This results in an even stronger mechanical stress of the seal label, whereby this tears more reliably in the manipulation attempt, for example, at punched edges.
  • the securing structure is formed from an at least partially transparent material.
  • This embodiment offers the advantage that any counterfeit security features that may be present in a seal label are not covered by the security structure.
  • information may be printed on the seal label, which remain visible despite a security structure due to a transparent design.
  • a securing structure made of a transparent and additionally brittle material it can be achieved that, in the case of a manipulative intervention, the securing structure loses its transparency and, for example, becomes opaque. In this way, a further securing means is created by the securing structure, by means of which a manipulation attempt is recognizable.
  • the material of the securing structure may also be designed such that it changes permanently when exposed to temperature, for example via a hot air blower. This material then undergoes a so-called thermal break.
  • One of the most common changes in heat influence is a change in color. In this way, would be recognized by the securing structure when a manipulative heat input has been made.
  • the thickness of the securing structure varies. This creates a three-dimensionally structured surface for the security structure. This in turn can be used to provide another securing means, since replicating the three-dimensionally structured surface after a manipulation attempt can represent a significant hurdle.
  • the same can be structured with regard to its material properties. It is conceivable that one part of the securing structure is relatively flexible, while another area is brittle. In this or another structuring of the security structure via its material properties, partial areas with different material properties encounter each other. As a result, when the seal label is raised by means of a razor blade, the behavior of the security system becomes virtually unpredictable. The probability that the seal label is destroyed in such a manipulation attempt, thereby increases considerably.
  • a structuring of the security structure can take place such that an information is encoded in the structure. This information may be read out by scanning or otherwise, and compared to a setpoint of the security structure of the subject to be secured. For this purpose, for example, by means of a database, a serial number of the object to be protected can be compared with the information read out and, if the information and serial number match, it can be concluded that the object is an incorrect one. In this way, an optical machine-readable evaluation for verification of the security structure is possible. This increases counterfeit security as well as manipulation security.
  • the security structure can be structured in several subregions.
  • the subregions may be spaced apart from each other or, in particular in a further structuring of the securing structure, also touch.
  • Spaced subregions can be formed, for example, by parallel lines, for example sine curves, triangular curves, saw teeth or arbitrarily shaped line trains.
  • the lines can have a constant width, but can also vary in width.
  • the sections may also have a cut in the form of rectangles, triangles, hexagons or other regular ones or irregular surfaces.
  • the boundaries of the subareas may be parallel or skewed. By the type of subdivision into subareas, in turn, a readable information can be coded.
  • connection can be formed by means of adhesion.
  • adhesion means that the interface layers of the seal label or the security structure by mechanical interaction undergo a mechanical cohesion.
  • a compound can be achieved for example by an adhesive which cures by means of UV light or heat.
  • a connection between the seal label and the security structure could also be achieved by at least partial merging.
  • the material of the sealing label merges with the material of the securing structure, when both are constructed on the basis of plastic.
  • Such a connection can be achieved, for example, during extrusion of the securing structure on the sealing label. It would also be conceivable for the securing structure to partially diffuse into the cover layer of the sealing label.
  • a mechanical connection between the seal label and the securing structure is formed. That the securing structure extends into at least one place in the seal label. In a particularly preferred embodiment, this can be achieved in that the sealing label has at least one opening and that the securing structure extends through this at least one opening and is thus arranged at least partially on both sides of the sealing label. In this way, a security structure is created in which a part forms a kind of anchor through the opening in the seal label. It is irrelevant in which way this anchor structure is constructed.
  • the anchor may be formed by a cuboid, a truncated cone, a cylinder, a truncated pyramid or another geometric shape.
  • the security system may have a protective layer.
  • the protective layer could be applied to the seal label and the securing structure. This ensures that the Security system is protected from moisture and other potentially unfavorable influences. This can reduce the risk of unintentional damage to the security system. In addition, this protective layer can also complicate a manipulation on. If, for example, the securing structure is formed of a transparent material, the protective layer would make the course of the securing structure or its subareas more difficult to recognize. This reduces the chances for an attacker to react to the course of the backup structure.
  • the security system could include pockets filled with a liquid. These pockets could be designed so that in a manipulative operation, the bag is destroyed and the liquid pours in the direction seal label. If the liquid is colored or otherwise capable of producing a visible change in the seal label and / or the securing structure, a further recognizability of an attempted manipulation can be created in this way.
  • the fluid-filled pockets could be made, for example, during an injection process of the securing structure.
  • the security system according to the invention can be used to secure a wide variety of objects. Documents made of paper or other materials can also be secured against manipulation and / or counterfeiting, such as housing assemblies or devices.
  • a very particularly preferred use of the security system according to the invention is the use in securing a housing.
  • a wide variety of electrical components could be arranged in the housing.
  • this housing is configured to receive a communication unit, most preferably a SmartMeter gateway.
  • the arrangement according to the invention then consists of a housing - the object to be protected - and a security system according to the invention.
  • the housing consists of at least two housing parts, which are joined together on at least one abutting edge.
  • the seal label and securing structure are arranged at least partially over the abutting edge.
  • the housing can be designed in various ways. It is important that the seal label and the securing structure can be attached to the housing in such a way that unauthorized opening of the housing can be recognized.
  • a housing, which is particularly well suited for this, is in the DE 10 2014 220 169 A1 described.
  • the security structure not only covers only a portion of the seal label, but also extends beyond the edge of the seal label.
  • the securing structure could additionally be connected at least in regions to the housing. In this way, a supplementary recognizability of a manipulative intervention is achieved. Because even if an attacker should succeed in unknowingly detaching the securing structure together with the sealing label from the housing and attaching it to another housing, the part of the securing structure that was connected to the housing will not be transferable to the "new" housing. This makes it evident when such a manipulation attempt has been carried out.
  • Fig. 1 shows a plan view of a known top hat rail housing with a view of the front. An oblique view of the housing is in Fig. 2 shown. A detailed description of the functioning and the individual elements of this housing can be found in the DE 10 2014 220 169 A1 are taken, the contents of which are hereby incorporated by reference.
  • the housing 1 comprises a first housing half 2 and a second housing half 3. In the housing halves 2, 3, a plurality of openings are formed, are accessible through the connections of an electrical assembly within the housing 1.

  • Fig. 3C shows a manipulated seal label, in which a securing means is triggered. Layers of the sealing label have separated from each other, so that the seal background has changed, whereby a manipulation attempt is recognizable.
  • Fig. 3D a remaining residue on the object to be secured is recognizable. In the in Fig. 3D this case is a lettering with the abbreviation of the Applicant.

  • the securing structure 10 is formed by a plurality of line-shaped partial areas, which are formed as irregular lines.
  • Two line-shaped first partial regions 11 are arranged parallel to one another and in a direction essentially parallel to the abutting edge 8.
  • Four second line-shaped subregions 12 are likewise arranged parallel to one another and in a direction substantially perpendicular to the abutting edge 8.

  • a sealing label 7 is arranged over a abutting edge 8 between a first housing half 2 and a second housing half 3.
  • the sealing label 7 consists of an adhesive layer 13 and a cover layer 14, wherein the adhesive layer 13 is mounted on the housing 1 to be secured and thus adheres to the housing halves 2, 3.
  • the securing structure 10 partially covers the seal label 7 and extends beyond the edge of the seal label.
  • the securing structure 10 is connected to the covering layer 12 of the sealing label 7 and thus to the sealing label 7 itself.
  • the part of the securing structure 10 which extends beyond the sealing label 7 is likewise at least partially in contact with the housing or the housing halves 2, 3 connected.
  • the securing structure 10 has a structured surface and thus forms a 3D structure. Furthermore, it can be seen that securing structure 10 conforms to the edge of the sealing label. As a result, insertion of a razor blade or another sharp object between adhesive layer 11 and housing part 2, 3 is significantly more difficult. Even if you succeed in inserting a razor blade, the irregular structure caused by the securing structure will cause the razor blade to lift the security system very differently. In areas without a security structure, the seal label will only be raised in a small area in front of the razor blade. On the other hand, an area with a securing structure will be stiffer and will be stressed with forces by the insertion of the razor blade in a larger area in front of the razor blade. In this way, significantly different stresses of the seal label arise when inserting the razor blade. Thus, the security structure favors the tearing of the seal label and thus the triggering of a securing means in this manipulation attempt.

Should it have been learned by manipulation of another device, how and where the different structures are positioned, this does not necessarily result in the position on the object to be attacked. This can be further enhanced if the structures are varied in different security systems.
  • Another training can prevent a reduction or a deduction.
  • Label thickness and background texture significantly determines the degree of severity of severity by tools (e.g., razors).
  • the layer thickness plays a crucial role in an attack scenario with heat.
  • the removal of the cover layer including adhesive layer can be made difficult in addition to the choice of a thin layer thickness by using an additional layer with different material properties compared to the substrate and film and glued to the substrate. This prevents a Unterhebung.
  • This effect can be reinforced by the fact that the seal label is arranged in housings in a recess or a pocket. A round border is not always advisable, as this creates a "frame" that can hold the film in shape. Unless a solid mass / frame is inserted between a bag with a roof that covers the seal. In the attempted trigger, tear points allow the seal to be destroyed.
