Abstract:
A method and apparatus for proving an integrity status of an outer packaging. The outer packaging covers an item and includes a modification of a foil provided for the outer packaging. A picture of a section of the outer packaging is recorded and a reference to a feature of the modification of the foil is analyzed. The integrity status of the original outer packaging is proved by storing the reference with respect to the original outer packaging for further use, wherein the outer packaging is uniquely identifiable by using the reference. The integrity status of suspect outer packaging is determined by comparing the reference of the suspect outer packaging with the reference of the original outer packaging. This allows using the outer packaging itself to be used for determining its integrity and may, thus, support avoiding a willful tampering or manipulation of the outer packaging.

CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This is a continuation of application no. PCT/EP2015/066755 filed Jul. 22, 2015 which claims priority from EP 14178938.8 filed Jul. 29, 2014, the disclosures of both of which are incorporated herein by reference. 
     
    
     BACKGROUND 
     1. Technical Field 
       [0002]    The present disclosure relates to a method and an apparatus for proving an integrity status of an outer packaging as well as for determining the integrity status of a suspect outer packaging. The disclosure further relates to a computer program for performing the mentioned methods as well as to a data carrier having a data structure stored thereon, which, after loading into a computer or a computer network, is capable of executing the methods. 
       2. Description of the Related Art 
       [0003]    The determination of the integrity status of a packaging is a technology known from the cigarette industry, such as in EP 0 330 495 A2, EP 0 902 275 A1, EP 1 420 381 A1, DE 10 2008 062 370 A1, WO 2001/024141 A1, WO 2001/030654 A1, or WO 2001/079092 A1, where it is, generally, used for determining defects during manufacture of an outer packaging for cigarettes comprising a transparent folded wrapper, but may also be employed in other areas, in particular in the food, medical, pharmaceutical, and/or cosmetic industry as, for example, in U.S. Pat. No. 3,899,295, U.S. Pat. No. 5,515,159, US 2012/013734 A1, or U.S. Pat. No. 7,142,707 B2. 
         [0004]    For this purpose, U.S. Pat. No. 5,515,159 discloses an on-line inspection of opaque, translucent and transparent elastomer sealed flexible and semi-rigid packaging seals, wherein, in case of highly reflective opaque seals of various elastomers and colors, low incident angle structured side lighting is used to locate and define the seal and highlight defects within the sealed area. For transparent, i.e. highly light transmissive seals, back lighting of the packaging is further provided in order to locate and classify defects within the seal boundaries. The images generated are used to determine whether the outer packaging is accepted, possibly accepted, or rejected based upon the quality of the seal area and the presence of any defects in the seal boundaries. 
         [0005]    U.S. Pat. No. 7,142,707 B2 describes an apparatus comprising a computer component which receives at least one image of a packaging material, wherein the computer component employs an analysis of the image to determine a packaging integrity of the packaging materials by comparing optical features, such as transmittance, absorption, fluorescence excitation, or deformation of the packaging or of graphics, or by an identification of bright regions within the outer packaging, in particular by using low-angle incidence of radiation. 
         [0006]    WO 2001/030654 A1 proposes to use at least one label, wherein the label comprises, in an encoded form, at least one characteristic feature of a packed article, in particular of a packed group of cigarettes, wherein the label will be destroyed when opening the outer packaging, such as for taking a cigarette, wherein the encoded form is compared with the characteristic feature in order to reveal falsifications by deviations or recurring identical matches. Alternatively, WO 2001/024141 A1 describes providing individual articles, such as each item in a group of cigarette, with characteristic, externally detectable markings, wherein the markings are encoded and applied to the outer packaging, in particular in form of a label, wherein a comparison between the externally detectable markings and the encoded form on the outer packaging allows determining its integrity. 
         [0007]    EP 0 330 495 A2 discloses a packet inspection system being capable of high speed sensing and evaluation of packaging integrity. The system is capable of measuring predetermined parameters of an outer packaging, e.g. cigarette packages, comparing the measured parameters with predetermined values, evaluating from the measured parameters the integrity of the outer packaging and determining whether such an outer packaging is acceptable or, alternatively, should be rejected. Herein, the measured packaging is compared to a reference packaging to achieve a qualitative evaluation of the packaging structure with respect to wrapper centering alignment, wrapper placement skew, closure stamp alignment, closure stamp skew, flap closure, wrapper foil condition, and packaging shape. A similar inspection system is disclosed in EP 0 902 275 A1. 
         [0008]    However, the known state of the art, on one hand, requires an additional piece, such as a seal, which may itself be subject to manipulation in order to demonstrate integrity of the outer packaging and/or, on the other hand does not allow pursuing the respective good over the whole supply chain. 
       SUMMARY 
       [0009]    The present disclosure provides a method and an apparatus for proving an integrity status of an outer packaging as well as for determining the integrity status of a suspect outer packaging, which at least partially overcome the problems and shortcomings of such methods and devices known from the state of the art. 
         [0010]    The present disclosure also provides a method and an apparatus for determining the integrity status of the packaging which allows pursuing the respective items covered within the outer packaging over the whole supply chain without any requirement to apply a separate piece for demonstrating its integrity, such as a seal, to the outer packaging in order to be able to detect a manipulation of the outer packaging. 
         [0011]    Disclosed herein is a method and an apparatus for proving an integrity status of an outer packaging, a method and an apparatus for determining the integrity status of a suspect outer packaging, a computer program for performing one or more of the methods according to the present disclosure and by a data carrier having a data structure stored thereon, which, after loading into a computer or computer network, is capable of executing one or more of the methods according to the present disclosure. Preferred embodiments, which might be realized in an isolated fashion or in any arbitrary combination thereof, are described herein. 
         [0012]    As used herein, the terms “have”, “comprise” or “include” or any arbitrary grammatical variations thereof are used in a non-exclusive way. Thus, these terms may both refer to a situation in which, besides the feature introduced by these terms, no further features are present in the entity described in this context and to a situation in which one or more further features are present. As an example, the expressions “A has B”, “A comprises B” and “A includes B” may both refer to a situation in which, besides B, no other element is present in A (i.e. a situation in which A solely and exclusively consists of B) and to a situation in which, besides B, one or more further elements are present in entity A, such as element C, elements C and D or even further elements. 
         [0013]    Further, it should be understood that various terms used throughout this disclosure and claims should not receive a singular interpretation unless it is made explicit herein. By way of non-limiting example, the terms “item,” “modification,” “foil,” to name just a few, should be interpreted when appearing in this disclosure and claims to mean “one or more” or “at least one.” All other terms used herein should be similarly interpreted unless it is made explicit that a singular interpretation is intended. 
         [0014]    Further, as used herein, the terms “preferably”, “more preferably”, “particularly”, “more particularly” or similar terms are used in conjunction with optional features, without restricting alternative possibilities. Thus, features introduced by these terms are optional features and are not intended to restrict the scope of the invention in any way. The invention may, as the skilled person will recognize, be performed by using alternative features. Similarly, features introduced by “in an embodiment” or similar expressions are intended to be optional features, without any restriction regarding alternative embodiments of the invention, without any restrictions regarding the scope of the invention and without any restriction regarding the feasibility of combining the features introduced in such way with other optional or non-optional features of the invention. 
         [0015]    Generally speaking, the present methods and apparatuses are suitable for proving and determining an integrity status of an outer packaging. As further used herein, the term “outer packaging” refers to an enclosure which may at least partially, preferably completely, cover an item, such as a good or a product, in particular for storage, distribution, and sale. In particular contrast to other packages, such as an inner packaging, the outer packaging may be accessible and, especially, visible from the outside around the respective outer packaging. In this respect it may be mentioned that, particularly depending on the specific field in which the outer packaging is employed, the outer packaging may also be denoted by other terms which are commonly used for such kinds of objects, such as “package”, “packing”, “wrap”, “wrapper”, “wrapping”, “bundle”, sealing“, or “vacuumization”. Applying an outer packaging may be performed due to a number of different purposes, including but not limited to providing a protection for at least one item comprised within the outer packaging, such as a protection from mechanical, physical, chemical, biological or environmental interference, such as from shock, vibration, electrostatic discharge, radiation, dust, vapor, atmospheres, or contamination, or from interference with other substances, for improving transport properties, such as improved convenience, portion control, containment, or agglomeration of individual items, for providing a suitable substrate for a transmission of information, in particular by attaching respective labels to the outer packaging, as well as for improving security and marketing performances. 
         [0016]    With particular regard to the present disclosure, the outer packaging may be considered as an original outer packaging as long as the outer packaging may be genuine and not tampered. In contrast hereto, a suspect outer packaging may be considered as an outer packaging which may or which may not be identical with the original outer packaging but which may have been tampered with for any reason, such as to remove at least one item from the outer packaging or to replace at least one of the original items by a counterfeit item which may allegedly create an impression as being identical to the original item. A willful tampering or manipulation may particularly occur in a case in which the at least one item comprised in the outer packaging may be of some esthetic or monetary value, such as with jewelry, watches, pieces of art, rare artifacts, microprocessors, or pharmaceuticals. In some cases it may be easy to identify a suspect outer packaging since the suspect outer packaging might differ with respect to any property from the original outer packaging, such as in a case where traces may be present which may be indicative of a breaking and a subsequent reclosing of the respective outer packaging. On the other hand, the tampering of the outer packaging may have been accomplished in a quality that the suspect outer packaging may not show any evidence, whether obvious or difficult to access, which would make it distinguishable from the original outer packaging in this way. Consequently, a suspect outer packaging might be one of a group consisting of the original outer packaging and of the tampered outer packaging. 
         [0017]    As further used herein, the “item” may be any physical object which may at least partially, preferentially completely, covered by an outer packaging as described above and/or below. Hereby, it is of no particular relevance whether the item itself may be of any value or whether the item, such as a document or an inner packaging, refers to or comprises another item which may be of some value, either in a commercial view, a personal view, or any other view. In a number of cases the inner packaging of any kind may comprise at least one item. First, the item itself may be of a consistence, such as a gel, a liquid, a gas, or of any other form which may not exhibit a steady solid form, that a particular kind of inner packaging may be required for storing, transporting, trading, and any other action referring to the item. Second, the item may be furnished with any kind of inner packaging, for example, for any commercial or trading reason, such as for improving storability, durability, stability, or keeping properties of the item, for equipping the item with an inner packaging which comprises a specific style or design, particularly for transport or storage reasons, or for improving the optical appearance of the item such as for esthetic or trading reasons. Third, there may also be legal or statutory reasons which may require the item to be furnished with an inner packaging, such as for medical drugs. Particularly within the pharmaceutical industry, but not limited thereto, each substance which may comprise, within a first respect, a solid body, such as a powder, a pill, a tablet, or a preparation, within a second respect, a liquid, such as a liquid formulation, an emulsion, or a serum, or, within a third respect, a gas, such as an aerosol, are comprised in at least in one inner packaging, which may further be comprised itself in at least one additional packaging, which is usually referred to as the outer packaging as described elsewhere. Thus, the item may refer to the physical object itself, to a label, a document, or any other article which may accompany the physical object, or to at least the one inner packaging which may comprise the physical object. Consequently, the item may not only be selected from the physical object itself but also from an accompanying article or from any other object which may be employed as the inner packaging in form of a primary packaging for the physical object, such as a bottle, a syringe, a vial, an ampoule, a carpule, a blister, and/or in form of a secondary packaging such as a cardboard box, a folding box, or a hangtag. In this regard, it is of no relevance whether the inner packaging completely or only partially encloses the object. 
         [0018]    With regard to the present disclosure, the at least one item may preferably also be arranged on at least one pallet. As used herein, the term “pallet” may refer to a primarily flat structure comprising at least one deckboard which is supported by at least two, but usually three or four, stringers, wherein the structure is configured for supporting at least one item, preferably a number of items which can be treated together as a so-called “bundle”, in particular for the purpose of providing a stable substrate whereon the item or the bundle of items may be located, stored or moved, such as by using a forklift or a pallet jack. In general, the pallet may comprise a mechanical stable material, in particular wood, metal, or a suitable plastic, cardboard or paper. In this preferred embodiment, wherein the at least one item is placed on the at least one pallet, the outer packaging may not only cover the at least one item but, additionally, may cover the at least one pallet at least partially, such as the top of the pallet adjoining to then location where the at least one item is placed. This kind of arrangement might be useful for further protecting and securing the at least one item. However, it is emphasized here that the present disclosure is equally applicable to items, such for food, medicals, pharmaceuticals, and/or cosmetics, which may be covered by the outer packaging without first being placed on at least one pallet. 
         [0019]    In further accordance with the present disclosure, at least one foil is provided for manufacturing the outer packaging. As used herein, the term “foil”, which may also be denoted as a “film”, relates to a quasi-two dimensional body, wherein the quasi-two dimensional body may particularly exhibit a considerable extension in two dimensions, which are usually known as “length” and “width” of the foil, whereas the third dimension of the body, usually referred to as a “thickness” of the foil, exhibits an extension being much smaller than the considerable extension with respect to the other two dimensions. As a typical example, the thickness of a specific foil may, thus, be in the range from 1 μm to 100 μm, whereas the width may be in a range from 10 cm to 2.5 m while the length may range from 1 m to 100 m, in some cases practically only depending on the size of a so-called “endless tape” or “continuous tape”, which constitutes a foil being rolled-up for further use by unrolling the required portion. In order to be able to provide the foil as endless or continuous tape, the thickness of the foil may usually be required to stay below an experimentally determined value; otherwise it may not be possible to roll up the foil. Generally, the foil is selected from one or more of: a plastic foil, which might predominantly exhibit clear, lucent, or (semi-)transparent properties; a metal foil, preferably an aluminum foil, which might particularly show highly reflecting properties; a sheet of paper. However, other choices may be appropriate under specific circumstances. 
         [0020]    Thus, the outer packaging is formed by using the at least one foil in order to at least partially, in particular completely, enclose the at least one item and, if applicable, also at least the top of the pallet on which the at least one item is placed. In some cases it might be advantageous to employ more than one foil to cover the respective item, such as in a case where the width of the foil turns out to be too small or where the thickness of a single foil may not be sufficient for providing enough stability of the outer packaging. In order to accomplish an optimal quality as possible of the outer packaging, in particular to further improve the stability of the complete packaging and, thus, to avoid an early opening, the at least one item, especially for larger items, may additionally be secured with at least one strapping which could be further affixed around the complete packaging comprising the at least one item and the corresponding outer packaging. 
         [0021]    By forming the outer packaging through applying the at least one foil to the at least one item, at least one modification is introduced into the at least one foil. As used herein, the term “modification” of the at least one foil refers to a development of at least one feature within the foil which was not present in the foil prior to the modification. In a particular preferred embodiment, the at least one modification of the foil is introduced into the foil by at least one of wrapping, stretching, shrinking, or otherwise putting the foil around the at least one item and, if applicable, around at least the top of the pallet on which the at least one item is placed. Herein, the foil which may be used for covering the at least one item may be taken from a roll of foil, but the foil may equally be provided in the form of a pouch or sleeve. However, other kinds of foil may be feasible for specific purposes. 
         [0022]    As used herein, the term “wrapping” refers to covering at least a part of the at least one item with a foil which is designated at least as a part of the outer packaging. 
         [0023]    As further used herein, the term “stretching” or “stretch wrapping” refers to covering the at least one foil, in particular where the foil comprises a plastic foil, around the at least one item, wherein an inherent elastic recovery of the foil allows keeping the at least one item tight within the boundaries of the foil. For this purpose, the foil may comprise a linear low-density polyethylene, usually abbreviated to “LLDPE”, since LLDPE usually exhibits high adhesive properties together with a considerable tensile strength. However, other types of polyethylene (PE) or polyvinylchloride (PVC) may also be employed. In a particular preferred embodiment, a so-called “palletizer” may be used, i.e. an apparatus which provides automatic means, such as robotics, for placing the at least one item onto a pallet and, subsequently, covering the at least one item and, if applicable, at least the top of the pallet with the foil in form of a stretch wrap in order to provide the desired outer packaging. 
         [0024]    In contrast hereto, the term “shrinking” or “shrink wrapping” refers to applying at least one foil, which particularly comprises a plastic foil, rather loosely around the at least one item and, subsequently, curing the plastic film with heat in order to accomplish a shrinking of the foil in a manner that it, preferentially tightly, covers the at least one item at least partially, in particular completely. For this purpose, heat may be applied with a heat gun, such as a hand-held gas or electric heat gun. Especially for a mass production, the at least one item at least partially covered with the film may be provided on a conveyor belt for passing through an appropriate heat tunnel. The plastic foil which may be used as shrink wrap usually comprises a polyolefin, but other polymers, such as PVC, PE, or polypropylene (PP), may also be employed. In particular for food, a coextrusion and a lamination which may comprise a number of different layers are preferably used as shrink wraps. The packaging may, thus, comprise a thin plastic film which may be used for covering items, such as food, for keeping them fresh over a longer period of time, in particular by using a shrink wrap. For covering food items, these kinds of packaging may also be denoted as “plastic wrap”, “food wrap”, “cling film”, or “cling wrap”. 
         [0025]    As mentioned above, at least one label may be attached to the outer packaging. As used herein, a “label” refers to a substrate which is attached on the outer packaging and which may present data in alphanumeric, graphic or electronic form that is used for providing information which is related to the at least one item as comprised within the packaging and/or the outer packaging itself. The information as presented on the at least one label may include one or more of addresses, such as at least one sending and/or at least one receiving party, codes, such bar codes, data matrix codes QR codes, Electronic Data Interchange (EDI), identification codes or other product codes, such as a universal product code, a Serial Shipping Container Code (SSCC), Radio-Frequency Identification (RFID) labels, country of origin labels, registration marks, trademarks, symbols for product certifications, proof of purchase marks, notes providing conformance to a regulation, such as to a weight and measures accuracy regulation, e.g. a CE marking, environmental and/or recycling symbols, such as a recycling code, a resin identification code and/or a “Green Dot”, special information symbols for hazardous or dangerous goods, food contact material symbols, such as an oval-shaped EC identification mark, health marks for food safety, quality insurance signs, calibration and/or troubleshooting cues. As will be described below in more detail, at least one label attached to the outer packaging may equally be employed for storing at least one reference with regard to the original outer packaging for further use in a method for determining the integrity status of a suspect outer packaging. 
         [0026]    The substrate of the label may preferably be shaped as an adhesive tag or sticker, as such comprising a thin sheet of paper or plastic affixed to a double-sided adhesive layer, which may be attached to the packaging by using a manual, a semi-automatic or, preferably, an automatic label dispenser. Preferably, the label may exhibit an optical contrast with regard to the packaging to which it is attached to, in particular by employing a thin sheet of a preferably white or bright substrate exhibiting the advantageous optical contrast to the material of the packaging which, in case of a plastic foil, might predominantly show clear, lucent, or (semi-)transparent properties, or in case of metal foil, preferably an aluminum foil, might particularly exhibit highly reflecting properties. 
         [0027]    As already mentioned above, by a modification process comprising the forming the outer packaging through applying the at least one foil to the at least one item, the foil itself undergoes at least one modification. As a result of the modification process, the foil comprises at least one feature which is related to the modification as introduced by the modification process into the foil. According to a continuous observation of the modification process and its results as well as being particularly suited for being used in the methods according to the present disclosure, the at least one feature of the modification of the foil is preferably selected from one or more of:
       at least one fold, i.e. an undulating shape, over at least one specific section of the outer packaging being introduced into the foil as a result of the modification; and/or   at least one variation of a transparency and/or of a color of the at least one foil with regard to the respective property of the foil prior to the modification;   at least one property of at least one edge, wherein the edge may be comprised within the outer packaging due to a respective wrapping of the foil around the at least one item;   at least one stain which may, in general unintentionally, be introduced into at least one location on the foil by the modification;   at least one variation of the features over at least one specific section of the outer packaging, in particular, if at least two features are present, at least one variation of the at least two features.       
 
         [0033]    As used herein, the term “section” may actually refer to a part of the outer packaging, but, depending on the selected perspective, may also relate to one, two, or three partial or whole sides of the outer packaging as being recorded in a single picture. 
         [0034]    With particular regard to the present disclosure, the term “fold” may refer to an undulated shape which might have developed in a part of the outer packaging, in particular after stretching or shrinking the foil which may, particular tightly, cover the at least one item as comprised by the outer packaging. Herein, the undulated shape may exhibit a sinusoidal, a wavelike or a rippled form particularly perpendicular with respect to a surface of the foil in a portion of the outer packaging. The ripples within the undulated shape may, in some case over a considerable area, form a regular sinusoidal variation of the at least one plastic film comprised within the packaging. However, overtones which might comprise a sequence of sine waves of different amplitudes as well as irregular patterns may also be observable within the areas where the undulation has developed. 
         [0035]    Alternatively or in addition, the at least one foil used as the outer packaging may exhibit a variation with regard to the transparency and/or color of the foil when compared with the respective property of the foil before it underwent the modification. In particular due to a stretching and/or shrinking of the foil and depending on its inherent material properties during the modification process, the thickness of the foil may be slightly reduced within at least one specific area which may lead to a change of the optical properties of the foil within the specific area. Alternatively or in addition, the foil may be folded, pleated, creased, wrinkled, dragged or pushed together during the modification process which may result in a further change of the transparency and/or color of the foil. These kinds of changes are particularly obvious for a plastic foil but comparable features may also be observed in foils comprising a metal or a paper. Consequently, the transparency and/or the color of the foil which might be altered as a result of the modification may, thus, be observable as one of the features which particularly are suitable for the purpose of the present disclosure. However, further optical features, such as an observation of a phase and/or a polarization shift might as well be employed. 
         [0036]    Alternatively or in addition, the at least one foil used as the outer packaging may exhibit at least one edge comprised within the outer packaging due to a respective wrapping of the quasi-two dimensional foil around the at least one three-dimensional item. With regard to the present disclosure, a location, a form, or a reflectivity of the edge may be suitable to be employed as the at least one feature of the modification. However, other properties of the edge may also be applicable for this purpose. 
         [0037]    Alternatively or in addition, the at least one foil may exhibit at least one stain which may, in general unintentionally, be introduced into at least one location on the foil by touching and modifying the foil during manufacturing the outer packaging covering the at least one item. The outer packaging may, thus, exhibit at least one location where an amount of dirt, sweat, color residues, or a fingerprint, such as of a human fingertip or of a robot being employed within a palletizer, may be placed. With particular regard to the present disclosure, a location, a form, or a reflectivity of the stain may, further, suitably be employed as the at least one feature resulting from the modification. However, the stain may exhibit other properties which may also be applicable for this purpose. 
         [0038]    Alternatively or in addition, the at least one variation of the features, whether previously mentioned or not, may be observable over at least one specific section of the outer packaging. This selection might preferably be applicable to distinguish contents of different sections of the outer packaging, such as sections in which a considerable number of various features may be observed, and other sections in which a only very few or no features may be present. As will be explained below in more detail, a density of features within a specific section may also be evaluated by applying respective evaluation methods to the respective section. 
         [0039]    In a first aspect, the present disclosure relates to a method for proving an integrity status of an original outer packaging. As used herein, the term “proving” relates to acquiring and storing technical features which characterize the respective outer packaging in a manner that the outer packaging may, subsequently, be uniquely identifiable by using the stored characteristic technical features which relate to the outer packaging. 
         [0040]    As further used herein, the “integrity status” of an outer packaging provides a value which defines whether a suspect outer packaging may be considered as the original outer packaging whose integrity is under question or not, i.e. an original or a tampered outer packaging. As further used herein, the outer packaging may be considered as the original outer packaging as long as the outer packaging itself may not be altered. Consequently, the method for determining the integrity status may, within a first respect, comprise a method for determining a verification of a suspect outer packaging or, within a second respect, comprise a method for determining a falsification of a suspect outer packaging, depending on the purpose and/or circumstances under which the method may be performed. In other words, the present method may be performed in a case in which it is desired to confirm the integrity of the suspect outer packaging. On the other hand, the present method may also be applied in a case in which the integrity of the suspect outer packaging may be discarded for any reason. Furthermore, the method may also be used under circumstances in which it may be desired to find an answer to an open question whether the outer packaging under investigation may be the true original outer packaging to be verified or whether the suspect outer packaging may be a tampered outer packaging pretending to be the original outer packaging. 
         [0041]    In this regard, the present method may deliver a Boolean value which may be designated by TRUE or FALSE, by 1 or 0, or by any other designation and which may comprise the integrity status of the outer packaging determined by application of the present methods. Alternatively, the present method may deliver an absolute value or, more particular, a relative value, such as a percentage of accordance between two pictures under comparison, which may comprise an indication about the integrity status of the outer packaging determined by application of the present methods. For this purpose, it may be preferable to define a threshold, above which the integrity may be assumed and below which the integrity may be denied, or vice-versa. In addition, therefrom a result, for example, in form of a Boolean value as described above may be acquired. This value, whether Boolean or not, may further be employed by a user of the present methods for any purpose, e.g. as an entry into a specific database which may comprise such kind of values, for producing an optical signal or an audio signal or a signal of any other kind upon determining the suspect outer packaging to be a tampered outer packaging, or for separating an object which comprises the suspect outer packaging which may have been falsified by the method from an inspection line. However, the present method may be applied under various other circumstances and for any other purpose, which may particularly be based upon any specific need of the user. 
         [0042]    According to the present disclosure, the method comprises the following steps step a) to c). Herein, the steps a) to c) are preferably performed in the given order, commencing with step a) and finishing with step c), still, other orders may be feasible. Further, it may be possible to perform two or more of the steps simultaneously or in an overlapping fashion. Further, it may also be feasible to perform one, two or more of the steps repeatedly, not depending on the fact whether other steps may be equally repeated. Further, additional steps may be comprised, irrespective whether the additional steps may or may not be mentioned in the following. 
         [0043]    According to step a) of the present method for proving the integrity status of an original outer packaging, at least one picture of at least one section of the outer packaging is recorded. As further used herein, the “picture” may comprise an optical image of a section of the outer packaging which is recorded by using an optical system. Hereby, the picture may describe a one- or a two-dimensional representation comprising a number of pixels in each dimension which together form the picture of the respective section of the outer packaging, thus, constituting a basis for a further evaluation of the picture in order to analyze at least one reference to the at least one feature of the at least one modification of the at the least one foil with regard to the outer packaging comprising the at least one item. 
         [0044]    In this regard, the proving and/or determining of the integrity may require a picture of the section of the outer packaging which may exhibit a reasonable quality and a sufficient resolution, which may be of particular importance for a further comparison of two distinct pictures, such as in step d) as described below, a comparison between a picture of the respective section of the suspect outer packaging and a hereto distinct picture of the supposed or alleged corresponding original outer packaging. Since in case of a poor quality and/or a low resolution of the picture of the section of the outer packaging, the present method may provide distorted results, such that a tampered outer packaging may be mistaken for the original outer packaging, it may, therefore, be necessary to ensure, before analyzing a recorded picture of the respective section of the outer packaging, that the picture may comprise a reasonable quality and resolution. 
         [0045]    In particular for this purpose, it may be preferred to perform a transformation of the at least one picture as recorded for at least one section of the outer packaging. Herein, the term “transformation” may refer to at least one alteration of at least one element of the picture, such as a pixel or a further constituent of the picture, or the complete picture after the recording of the picture. In a particularly preferred embodiment, the transformation may comprise one or more of the following transformation processes:
       adjusting the picture, in particular in a manner that the at least one recorded section of the outer packaging actually comprises at least one feature of interest of the at least one modification of the at the least one foil;   rearranging a spatial orientation of the picture, in particular by aligning the picture in a manner that the at least one recorded section of the outer packaging comprising the at least one feature of interest constitutes a preferably rectangular shape, preferably as by spatially orienting the picture with respect to at least one recurring element, preferably by cropping at least one side of the picture, in particular, if applicable, by removing a part of the picture which shows the at least one pallet or a part thereof;   removing a spatial distortion within the picture, in particular with respect to a perspective geometry, preferably as by employing known methods for eliminating distortions;   performing a binary alteration of the picture, in particular by employing local binary patterns (LBP);   performing a color classification transition in the picture, in particular by a transition from one color space to a further color space, such as from an RGB (red, green, blue) color space to an HSV (hue, saturation, value) color space.       
 
         [0051]    In a preferred embodiment, a spatial orientation of the picture may be performed during the transformation process with particular regard to one or more of the following recurring elements: one or more edges of the outer packaging, which may, preferably, further be highlighted by respective marks, such as by a black, a white, or a color mark; a particular arrangement of at least one label, preferably of more than one label, on the surface of the outer packaging; one or more gaps between the at least two, but usually three or four, stringers which are adapted to support the at least one deckboard of the pallet. In this regard it may be preferable to rely on known features and, in addition, to employ a neural network which may be capable of both machine learning and pattern recognition. 
         [0052]    By employing at least one of the mentioned transformation processes, a good comparability of at least two distinct pictures may, thus, be achieved. In addition, further mechanisms may be applied to ensure a good readability of the features comprised within the image, in particularly with regard to the contrast of the image. In the field of image processing various methods exist which may be applied to determine the quality of a given optical image, such as a detection of a blur of the image or a frequency analysis of the image. 
         [0053]    In a preferred embodiment, the optical system employed for performing a method according to the present disclosure may comprise at least one element which may be selected from the group comprising: a camera, a flatbed scanner, a bar code hand-scanning device, a cell or a cellular phone, a laptop webcam, a smartphone, a tablet computer. However, any other optical system comprising a resolution which may be sufficient to resolve the characteristic features within the outer packaging may also be used. 
         [0054]    According to step b), at least one reference to at least one feature of the at least one modification of the foil is analyzed in the picture. In this regard, the at least one feature may, preferably, be selected from one or more of: at least one fold within the outer packaging; at least one variation of a transparency and/or a color of the outer packaging; at least one property of at least one edge within the outer packaging; at least one stain as comprised within the outer packaging; at least one variation of the features over at least one specific section of the outer packaging. 
         [0055]    According to the present disclosure, the at least one reference may be selected from one or more of: the at least one picture of the at least one section of the outer packaging, wherein the at least one section comprises the at least one feature; at least one quantity acquired for the at least one feature as comprised in the at least one picture of the at least one section of the outer packaging. Thus, the at least one reference may comprise the at least one picture in a form as recorded of the at least one section of the outer packaging, wherein the at least one feature of interest may be comprised. In a particular preferred embodiment, the at least one reference may, particularly, refer to the at least one picture after having performed a transformation of the at least one picture, wherein the transformation may comprise one or more of the transformation processes as described above, particularly in order to provide a good comparability of at least two distinct pictures, such as during the subsequent step d). 
         [0056]    Alternatively or in addition, the at least one reference may, preferably, be derived from a quantity which may be related to the at least one feature developed in the outer packaging as a result of the at least one modification of the foil as described above and/or below in more detail. For this purpose, a numerical value for this quantity related to one or more features as developed in the outer packaging due to the modification of the foil may be employed, wherein the quantity may also be denoted as “individual imperfection profile” of the outer packaging. However, other denominations are possible. 
         [0057]    In a preferred embodiment, the at least one quantity as acquired for the at least one feature is obtained from the picture of the at least one section of the outer packaging by using one or more of:
       a threshold, in particular a limit below which respective characteristics, such as a color, in the picture may be disregarded;   a feature extraction technique, in particular a Hough Transformation and/or a Watershed Filter, wherein the term “feature extraction technique” may generally relate to a method for reducing an acquired set of information into a reduced set of information in a manner that the reduced set comprises the desired feature;   an edge detection operator, in particular a Canny Transformation or a filter according to Sobel, Prewitt, Roberts, Marr-Hildreth and/or Haralick, wherein the term “edge detection operator” may generally refer to a method for identifying at least one location in an image where a brightness or an intensity may change sharply and, thus, exhibits discontinuities;   a texture classification technique, in particular applying local binary patterns (LBP), wherein the term “texture classification technique” may generally concern a method for extracting a shape, such as a mark or a stain, from a textured image;   a process for approximating periodic features, in particular a Fourier analysis, more particular a Fast Fourier Transformation (FFT), wherein the periodic features may particularly be represented or approximated by a sum of at least one trigonometric function.       
 
         [0063]    In this regard, it may be advantageous to select a specific section within the outer packaging which may exhibit a variation which might be above or below an average variation to be observable over at least one side of the outer packaging. Further, it might be especially useful to count the number of folds within the selected section and to identify its corresponding properties in more detail by employing the Canny Transformation and/or one or more of the above-mentioned filters. A similar procedure may be applicable to stains within the at least one selected section. Alternatively or in addition, at least two selected sections may be compared, in particular with regard to their corresponding transparency and/or color within the selected section which may be indicative of the respective thickness of the modified foil within the selected section. Alternatively or in addition, at least two selected sections may be compared, in particular with regard to a variation and/or density of features within the at least one selected section which may be indicative of a perturbation or a disturbance within the selected section. However, other kinds of deriving a numerical value for the quantity related to one or more features developed in the outer packaging as a consequence of the modification of the foil may be suitable. 
         [0064]    As a result, the at least one reference to at least one feature of the at least one modification of the foil with respect to the original outer packaging has, thus, been acquired during step b). The at least one reference with respect to the original outer packaging is, during subsequent step c), stored as the integrity status of the original outer packaging for further use, in particular at some time in the future, in order to be employed to determine on this basis the integrity status of a suspect outer packaging. 
         [0065]    In a particular preferred embodiment, the at least one reference with regard to the original outer packaging may be stored for further use by one or more of:
       applying the at least one reference to the outer packaging, such as in a form of a code, e.g. a bar code, a data matrix code, a QR code, as applied to a label attached to the outer packaging as described above in more detail;   generating a database record for the corresponding outer packaging, wherein the database record may at least comprise the at least one reference with regard to the original outer packaging and might, further, comprise a further reference to the original outer packaging, such as the SSCC code;   if applicable, storing the at least one reference in a separate storage device, such as an RFID chip, a USB chip, or a magnetic stripe, wherein the separate storage device may be attached to the at least one pallet.       
 
         [0069]    In a further preferred embodiment, the database record as generated during step c) may be transmitted to a database via one or more channels selected from: a wireless data transmission, a wire bound data transmission, a transmission via a computer network. Hereby, the exact details and manners of the transmission are of little relevance as long as the generated database record may be inserted into the database for further use during step d) of the method for determining the integrity status of the suspect outer packaging. In addition, by storing the further reference to the outer packaging, such as the SSCC code, too, it may, thus, be possible to easier identify the corresponding reference to the respective suspect outer packaging. 
         [0070]    In a particularly preferred embodiment, the method for proving the integrity status of an outer packaging may be part of a packaging process for packaging the at least one item, irrespective whether being placed on a pallet or not, into an outer packaging. This kind of performance may particularly ensure that data which may later be required for a determination of the integrity status of the suspect outer packaging may be stored within the database with little or no time delay, preferably directly within the packaging line. Such an approach may particularly be useful for decreasing the manipulation of an outer packaging. 
         [0071]    In a further aspect, the present disclosure relates to a method for determining the integrity status of a suspect outer packaging. The method according to the present disclosure comprises steps a), b) and d). These steps are preferably performed in the given order, commencing with step a) and finishing with step d), still, other orders may be feasible. Further, it may be possible to perform two or more of the steps simultaneously or in an overlapping fashion. Further, one or more steps may be performed repeatedly, depending or not whether other steps are equally repeated. The method may further comprise one or more additional steps, whether mentioned herein or not. 
         [0072]    For further details to the method for determining the integrity of a suspect outer packaging, reference may be made to the disclosure of the method for proving the integrity of an original outer packaging, as disclosed above and/or below. In particular, both step a) related to recording a picture of a section of the outer packaging and b) related analyzing a reference to a feature of a modification of a foil in the picture have already been disclosed there. Accordingly, the at least one reference with respect to the suspect outer packaging is, thus, acquired. However, in contrast to the method for proving the integrity of an original outer packaging, the corresponding result of step b) may, during subsequent step d), be employed to determine the integrity status of the suspect outer packaging on this basis. With regard to the at least one reference, the disclosure of the method for proving the integrity of the original outer packaging, as disclosed above and/or below, may also be taken into account. 
         [0073]    According to step d), the at least one reference with respect to the suspect outer packaging is compared with the at least one reference with respect to the original outer packaging as obtained during step b) within a comparing step. Hereby, a comparison of the at least one reference with respect to the suspect outer packaging with the at least one reference with respect to the original outer packaging allows determining the integrity status of the suspect outer packaging. As further used herein, “comparing” includes making a comparison between the at least one reference with respect to the suspect outer packaging with the at least one reference with respect to the original outer packaging with regard to their identity but also taking into account a tolerance level within which the integrity of the suspect outer packaging may be still assumed. Introducing a tolerance level may particularly allow taking into account inevitable adverse effects, such as deterioration, ageing, dirt, color residues or wear, which may affect the outer packaging during storage and/or transport. 
         [0074]    As already described above in more detail, the at least one reference may be selected from one or more of: the at least one picture of the at least one section of the outer packaging, wherein the at least one section comprises the at least one feature; at least one quantity acquired for the at least one feature as comprised in the at least one picture of the at least one section of the outer packaging. Thus, the comparing according to step d) may comprise comparing the at least one picture of the at least one section of the suspect outer packaging with the at least one picture of the at least one section of the original outer packaging either in a form as recorded, or, in particularly preferred, after a transformation which comprises one or more of the transformation processes as described above has been applied to the respective pictures, particularly in order to provide a good comparability between the at least two distinct pictures. Alternatively or in addition, the comparing according to step d) may comprise comparing at least one quantity related to the at least one feature in the suspect outer packaging, such as the individual imperfection profile of the suspect outer packaging, with at least one quantity related to the at least one feature in the original outer packaging, such as the individual imperfection profile of the original outer packaging. 
         [0075]    Since a further modification of the foil as comprised within the outer packaging may, thus, further modify the foil with regard to at least one reference and may, consequently, alter the at least one reference with respect to the outer packaging, a comparison according to step d) may indicate a tampering of the outer packaging in a time interval between the at least two distinct pictures which may be recorded for the same section of the corresponding outer packaging. 
         [0076]    The present method for determining the integrity status of the suspect outer packaging may, further, comprise a transmission step by which, preferably after one or more of the method steps step a) or step b), data may be transferred to a data processing unit via a computer network in such a manner that the further steps, after the transmission, may be performed by the data processing unit, wherein the integrity status of the suspect outer packaging may be returned by the data processing unit. This transmitting step may particularly be performed by at least one control unit which may be adapted to perform or to have performed at least method step a) as well the data transmission. The control unit may comprise a computer or a micro-computer, wherein the micro-computer may be part of the optical system, of a system which may control the optical system, or of a system which may be in connection with the optical system. Which kinds of data are transmitted by the control unit to the data processing unit may particularly depend at which stage during the performance of the present method the actual data transmission takes place. As an example, after step a) the at least one picture of the at least one section of the outer packaging as recorded by the optical system may be transferred to the data processing unit on which the further steps b) and d) may be performed until the integrity status of the suspect outer packaging may be determined and returned to the at least one control unit. As a further example, steps a) and b) may be performed locally until the control unit may transmit the at least one reference determined for the suspect outer packaging to the data processing unit where only the remaining comparison step d) may be performed until the integrity status of the suspect outer packaging may be determined and returned to the at least one control unit. In this particular embodiment it might be advantageous that the database may be one or more of comprised within the processing unit or operationally connected to the data processing unit. 
         [0077]    In a further aspect of the present disclosure, a proving apparatus for proving the integrity of an original outer packaging is disclosed.

Hereby, the database record may comprise the at least one reference with respect to the original outer packaging as well as further reference to the outer packaging, such as an SSCC code. In a particularly preferred embodiment, the proving apparatus is configured to perform the method for proving the integrity of the original item as described above and/or below. For further details of the proving apparatus, reference may be made to the method for proving the integrity status of an original outer packaging as described elsewhere. 
         [0079]    In a preferred embodiment, the proving apparatus may be part of a packaging apparatus for furnishing the at least one item with an outer packaging. This kind of embodiment may be particularly useful for strictly combining the packaging of the at least one item with the apparatus which generates the database record being related to the item. This arrangement may particularly allow ensuring that the at least one reference as stored on the item, in the database record and/or, if applicable, with the pallet may actually be related to the respective original outer packaging. Such a strong physical relationship of the mentioned devices may be particularly intended to reduce the risk of disappearing with relation to items of some value as comprised within the outer packaging. 
         [0080]    In a further aspect of the present disclosure, a determining apparatus for determining the integrity status of a suspect outer packaging is disclosed. In this regard, reference may be made to the description above and/or below referring to the corresponding method as well as to the proving apparatus. According to the present disclosure, the determining apparatus at least comprises at least parts A), B) and D), which may be assembled in any suitable fashion.

         [0081]    As described above for the proving apparatus, Part A) of the determining apparatus comprises a recording device being configured for recording at least one picture of at least one section of the outer packaging, whereas part B) comprises an analysis device configured for analyzing in the picture at least one reference to at least one feature of the at least one modification of the at the least one foil. However, in contrast to the proving apparatus, part D) of the determining apparatus comprises a comparing device configured for comparing the at least one reference with respect to the suspect outer packaging with the at least one reference with respect to the original outer packaging as stored as the integrity status of the original outer packaging for further use in a storing device according to part C) as described elsewhere in this description. By this comparison, the integrity status as defined above of the suspect outer packaging is determined. In a particularly preferred embodiment, the determining apparatus may be configured to perform the method for determining the integrity status of the suspect outer packaging as described above and/or below. For further details of the determining apparatus, reference may be made to the proving apparatus as well as to the method for determining the integrity status of a suspect outer packaging as described elsewhere. 
         [0082]    In a particularly preferred embodiment, the determining apparatus may be further adapted to control the transmission of data to a data processing unit. In this regard, the transmission of the data may be performed via one or more transmission means selected from a wireless data transmission, a wire bound data transmission, and/or a transmission via a computer network. Further details concerning the data transmission, the data and the data processing unit may be found elsewhere in this description. 
         [0083]    The present application further discloses and proposes a computer program, including computer executable instructions for performing both the method for proving the integrity of the original outer packaging and the hereto related method for determining the integrity status of the suspect outer packaging, when the program is executed on a computer or a computer network. Preferentially, the computer program may be stored on a computer readable data carrier. In this regard, the disclosure further describes a data carrier having a data structure stored thereon, wherein the data structure, after loading into a computer or a computer network, is capable of executing any or all methods as disclosed herein. As further used herein, a computer may comprise any device which may be capable of storing data and/or performing calculating steps and/or instructing steps. By way of example, this definition may not only include work stations and notebooks but also application-specified integrated circuits (ASICs) and field-programmable gate arrays (FPGAs). 
         [0084]    Preferably, referring to the computer-implemented aspects of the present disclosure, one or more of the method steps or even all of the method steps of any or all methods disclosed herein may be performed by using a computer or a computer network. Thus, generally, any of the method steps including provision and/or manipulation of data may be performed by using a computer or a computer network. Generally, these method steps may include any of the method steps. 
         [0085]    The disclosure further describes and proposes a computer program including computer-executable instructions for performing any or all methods according to the present disclosure in one or more of the embodiments enclosed herein when the program is executed on a computer or computer network. Preferentially, the computer program may be stored on a computer-readable data carrier. Thus, preferably, one, more than one or even all of method steps as indicated above may be performed by using a computer or a computer network, preferably by using a computer program. 
         [0086]    The disclosure further describes and proposes a computer program product having program code means, in order to perform any or all methods according to the present disclosure in one or more of the embodiments enclosed herein when the program is executed on a computer or computer network.

         [0089]    Finally, the disclosure proposes and describes a modulated data signal which contains instructions readable by a computer system or computer network, for performing any or all methods according to one or more of the embodiments disclosed herein. 
         [0090]    Preferably, referring to the computer-implemented aspects of the disclosure, one or more of the method steps or even all of the method steps of any or all methods according to one or more of the embodiments disclosed herein may be performed by using a computer or computer network.

         [0091]    The methods and devices according to the present disclosure are considerably distinguished from known methods and devices according to the state of the art and, thus, provide a number of advantages with regard to the state of the art. In addition to the well-known advantages of unit loads, particularly those which employ stretch wraps around palletized items, which are usually considered to be improved stability of products, more efficient handling and storage, some degree of dust and moisture protection, and some degree of tamper resistance and resistance to packaging pilferage, the present disclosure allows that the outer packaging itself may be used for determining the integrity of the outer packaging. 
         [0092]    This further purpose may equally be employed for one or more items which may be covered in a plastic foil, such as cellophane, without being placed on a pallet. 
         [0093]    In this regard, the present methods for proving and determining the integrity status of an outer packaging may, respectively, be employed for a fast and still reliable investigating of a plurality of outer packaging along the supply chain with respect to their integrity status and may, thus, help avoiding a willful tampering or manipulation in a case wherein the at least one item comprised in the outer packaging may be of some esthetic or monetary value, such as with jewelry, watches, pieces of art, rare artifacts, microprocessors, or pharmaceuticals. In contrast to the state of the art, the present methods for proving and determining the integrity status of an outer packaging may, respectively, are based on the observation that the outer packaging itself may comprise tamper-evident features which may be employed to help indicate tampering. Thus, in addition to other known measures which are commonly used for improved tamper resistance in order to deter the tampering of an outer packaging, the modifications introduced into the foil which, according to the present disclosure, constitute the outer packaging may advantageously be employed to help reducing risks of pilferage as well as theft and resale of items comprised in the corresponding outer packaging. 
         [0094]    Summarizing the findings of the present disclosure, the following embodiments are preferred:

       [0161]    Corresponding reference characters indicate corresponding parts or functionally comparable elements throughout the several views. Although the exemplification set out herein illustrates embodiments of the invention, the embodiments disclosed below are not intended to be exhaustive or to be construed as limiting the scope of the invention to the precise forms disclosed. 
       DETAILED DESCRIPTION 
       [0162]      FIG. 1  schematically depicts a well-known process for furnishing a number of items  110  which are placed on a pallet  112  by employing a foil  114  in order to provide an outer packaging  116  which, in this preferred example, covers both the items  110  and at least the top part  120  of the pallet  112 . However, it is emphasized here that the present disclosure is equally applicable when the number of items  110 , such as food, medicals, pharmaceuticals, and/or cosmetics, may only be covered by the foil  114  in order to provide the outer packaging  116  without any requirement to be placed on the pallet  112 . 
         [0163]    In this particular example, the foil  114  which is being used for providing the outer packaging  116  is a transparent plastic foil  118  which is, preferentially, taken from a roll  122  of so-called endless or continuous tape by unrolling a required portion of the foil  114 . According to the present disclosure, however, other kinds of foil, such as a metal foil, preferably an aluminum foil, or a sheet of paper, are equally applicable. By forming the outer packaging  116  through applying the foil  114  in order to cover at least the items  110 , at least one modification  124  is introduced into the foil  114 , wherein the modification  124  of the foil  114  causes a development of one or more features  126  within the foil  114  which were not present in the foil  114  prior to the modification  124 . 
         [0164]    Further, in this particular example, the modification  124  of the foil  114  is introduced here into the foil  114  by one or more of wrapping, stretching, or shrinking the foil  114  around the items  110  and the top  120  of the pallet  112  on which the items  110  are placed. In this regard, the plastic foil  114 ,  118  is preferably first wrapped around the items  110  as well as the top  120  of the pallet  112  by covering the items  110  and the top  120  of the pallet  112  with the foil  114  and, subsequently, stretched by employing an inherent elastic recovery of the plastic foil  114 ,  118  which allows keeping the items  110  as well as the top  120  of the pallet  112  tight within the boundaries of the plastic foil  114 ,  118 . Especially for a mass production, a palletizer, i.e. an apparatus providing automatic means, such as robotics, for placing the items  110  onto the pallet  112  and, subsequently, covering the item  110  and the top  120  of the pallet  112  with the plastic foil  114  may be employed for providing the desired outer packaging  116 . 
         [0165]    Alternatively, the plastic foil  114 ,  118  may rather loosely applied around the items  110  and the top  120  of the pallet  112  and, subsequently, cured with an application of heat in order to accomplish a shrinking of the plastic foil  114 ,  118  in a manner that it completely, preferentially tightly, covers the items  110  and the top  120  of the pallet  112 . Especially in mass production, the items  110  and the pallet  112  on which the items  110  are placed may be provided for achieving this purpose on a conveyor belt for passing through an appropriate heat tunnel. 
         [0166]    As already mentioned above and irrespective of the actual process as applied for performing the modification  124 , the modification  124  of the foil  114  causes a development of one or more features  126  within the foil  114  which were not present in the foil  114  prior to the modification  124  and which will be explained with regard to  FIG. 2  in more detail. 
         [0167]    In addition, one or more labels  128  may be attached to the outer packaging  116 , wherein the labels  128  provide an optical contrast with regard to the outer packaging  116 . For this purpose, the labels  128  are attached onto the outer packaging  116  for presenting data in alphanumeric, graphic or electronic form for providing information generally being related to the items  110  as comprised within the outer packaging  116 . Herein, the information may include addresses, bar codes, identification codes or other product codes, in particular an SSCC code, RFID labels, country of origin labels, registration marks, trademarks, symbols for product certifications, proof of purchase marks, notes providing conformance to a regulation, information symbols for hazardous or dangerous goods, food contact material symbols, quality insurance signs, calibration and/or troubleshooting cues, and others. 
         [0168]      FIG. 2  presents a more detailed schematic overview over the various features  126  as comprised within one side  129  of the outer packaging  116  which may, preferably, be used in the methods according to the present disclosure. As a result of the modification  124  of the plastic foil  114 ,  118 , the plastic foil  114 ,  118 , which constitutes the outer packaging  116  comprises in this particular example, a number of folds  130  are introduced into the plastic foil  114 ,  118  in an undulating shape over at least one specific section of the outer packaging  116 . Further, the plastic foil  114 ,  118 , which here constitutes the outer packaging  116 , comprises in this particular example a variation  132  of a transparency and color of within at least one specific section of the outer packaging  116  with regard to the respective property of the plastic foil  114 ,  118  prior to the modification  124 . Furthermore, edges  134  have been formed within the outer packaging  116  in this particular example mainly due to the wrapping of the plastic foil  114 ,  118  around the items  110  and the top  120  of the pallet  112 . Moreover, stains  136  in the form of a fingerprint  138  have, unintentionally, been applied in this particular example onto at least one location on the plastic foil  114 ,  118  which constitutes the outer packaging  116  after the modification  124 . However, other kinds of features  126 , such as stains  138  arising from sweat or from color residues, such as from unintentionally touching a human being or a colored object, respectively, may result from the modification  124 , too. 
         [0169]      FIG. 3  schematically displays a preferred embodiment of a proving apparatus  140  which is particularly configured for performing the method for proving the integrity status  142  of an original outer packaging  116 . Herein, the proving apparatus  140  comprises a camera  144  as an example of an optical system which is employed as a recording device  146  being configured for recording one or more pictures  148  of one or more sections  150  at one or more sides  129  of the outer packaging  116 . In this respect, it may particularly be useful to record a picture of four sides  129  of the outer packaging  116  which are perpendicular to the pallet  112 . Alternatively, it may be sufficient to record only a picture of a single side  129  of the outer packaging  116  which comprises the majority of the features  126 . 
         [0170]    Further, the proving apparatus  140  comprises an analysis device  152  which is configured for analyzing the pictures  148  of the sections  150  for retrieving at least one reference to one or more features  126  as introduced during the modification  124  of the plastic foil  114 ,  118  which constitutes the outer packaging  116 . For this purpose, the pictures  148  of the sections  150  are transferred from the recoding device  146  to the analysis device  152  by a transmission line  154  which may be wire-bound, wire-less or within a computer network. Accordingly, at least one of the pictures  148  of the sections  150  may be used as the at least one reference. Herein, a transformation of the pictures  148  may be performed, wherein the transformation may comprise one or more of the following transformation processes: adjusting the picture of the at least one section of the outer packaging; rearranging a spatial orientation of the picture; removing a spatial distortion within the picture; performing a binary alteration of the picture; performing a color classification transition in the picture. 
         [0171]    Alternatively or in addition, from a quantity which is related to the features  126  as developed in the outer packaging  116  as a result of the modification  124  of the plastic foil  114 ,  118 , an individual packaging profile  156  of the outer packaging  116  may be derived as a corresponding numerical value which may constitute or contribute to the at least one reference. 
         [0172]    In a preferred embodiment as employed in this example, the individual imperfection profile  156  of the outer packaging  116  is acquired by employing a process for approximating periodic features, such as the number of folds  130  as introduced into the plastic foil  114 ,  118  in an undulating shape over at least one specific section of the outer packaging  116 , in particular by employing a Canny Transformation or a filter according to Sobel, Prewitt, Roberts, Marr-Hildreth and/or Haralick. For this purpose, it may be advantageous to select the sections  150  within the outer packaging  116  in a manner that they exhibit a variation being above or below an average variation observable over one or more sides  129  of the outer packaging  116 . 
         [0173]    As a preferred example, the number  158  of the folds  130  within the selected section  150  of the outer packaging  116  may be counted. In addition, further corresponding properties of the folds  130 , such as a frequency of the undulating shape, may be identified in more detail by applying a Fourier Transformation, more particular a Fast Fourier Transformation (FFT), of the respective sections  150  Similarly, a number of the stains  136 , such as the number of the fingerprints  138 , within the selected section  150  of the outer packaging  116  may be counted. 
         [0174]    As a further example, two or more sections  150  on the outer packaging  116  may be compared with each other with regard to their corresponding transparency and/or color within the sections  150  in order to record the respective variation  132  which may be indicative of the corresponding thickness of the plastic foil  114 ,  118  within the sections  150  after the modification  124 . 
         [0175]    As mentioned above in more detail, other kinds of deriving the individual imperfection profile  156  from the respective features  126  in the outer packaging  116  may be applied, such employing one or more variation of the features  126  over one or more sections  150  in the picture  148  of the outer packaging  116 . 
         [0176]    Further, the proving apparatus  140  comprises a storing device  160  for storing the at least one reference, in particular a transformation of at least one of the pictures  148  and/or the individual imperfection profile  156 , for further use. 
         [0177]    In a first example (not depicted here), the storing device  160  may comprise a label  128  which is attached to the outer packaging  116  and which is configured for carrying the respective information. 
         [0178]    However, in the example as shown here, the individual imperfection profile  156  is transferred to the storing device  160  by means of a further transmission line  162 , which may be wire-bound, wire-less or within a computer network, wherein the storing device  160  is adapted for generating a database record  164  in a database  166 , wherein the database record  164  is related to the outer packaging  116  under investigation. In this particular example, each database record  164  comprises at least an identifier as a further reference  168  and the individual imperfection profile  156 , wherein both the further reference  168 , which may comprise an identification number of the outer packaging  116 , and the individual imperfection profile  156  are related to the outer packaging  116  in a manner that they allow uniquely identifying both the outer packaging  116  and its integrity status  142  over the complete supply chain. 
         [0179]    In further first example (also not depicted here), the storing device  160  may comprise a physically separate storage device, preferably an RFID chip, a USB chip, or a magnetic stripe, which may be attached to the at least one pallet  112 , wherein the at least one reference may be stored in the storing device  160  for further use. 
         [0180]      FIG. 4  schematically depicts a preferred determining apparatus  170  which is particularly configured for performing the method for determining the integrity status  142  of a suspect outer packaging  116 . In this particular example, the determining apparatus  170  also comprises the camera  144  as the recording device  146  being adapted for recording one or more pictures  148  of one or more sections  150  at one or more sides  129  of the outer packaging  116 . 
         [0181]    Further, the determining apparatus  170  again comprises the analysis device  152  being configured for analyzing the pictures  148  of the sections  150  for retrieving at least one reference to one or more features  126  as introduced during the modification  124  of the plastic foil  114 ,  118  constituting the outer packaging  116 . Also here, the pictures  148  of the sections  150  are transferred from the recoding device  146  to the analysis device  152  by the transmission line  154 . Accordingly, at least one of the pictures  148  of the sections  150  may be used as the at least one reference. Herein, a transformation of the pictures  148  may be performed, wherein the transformation may comprise one of the transformation processes as described above in more detail. Alternatively or in addition, from a quantity which is related to the features  126  as developed in the outer packaging  116  as a result of the modification  124  of the plastic foil  114 ,  118 , an individual packaging profile  156  of the outer packaging  116  may be derived as a corresponding numerical value which may constitute or contribute to the at least one reference. 
         [0182]    In contrast to the proving apparatus  140 , the determining apparatus  170  further comprises a comparing device  172  which is configured for comparing the at least one reference with respect to the suspect outer packaging  116 , in particular the at least one transformation of the pictures  148  and/or the least the individual packaging profile  156 , with the at least one reference with respect to the original outer packaging  116 , in particular the at least one transformation of the pictures  148  and/or the individual packaging profile  156  of the original outer packaging  116 , which have been stored for further use in the storing device  160  as described above. As already mentioned above, the comparison is preferably performed in a manner that it takes into account any tolerance levels within which the integrity of the suspect outer packaging may be still assumed, wherein the tolerance levels consider inevitable adverse effects, such as deterioration, ageing, dirt, color residues, or wear, which may affect the outer packaging  116  during its storage and/or transport. 
         [0183]    By this comparison the integrity status  142  of the suspect outer packaging  116  is finally determined. Since a further modification of the plastic foil  114 ,  118  which constitutes the outer packaging  116  usually further modifies the plastic foil  114 ,  118  with respect to the features  126  comprised within the at least one reference with respect to of the outer packaging  116 , in particular in the at least one transformation of the pictures  148  and/or in the least the individual packaging profile  156 . Thus, the pictures  148  and the individual imperfection profile  156  of the outer packaging  116  are very likely to be altered so that, consequently, a the comparing device  172  may provide a result being indicative of a tampering of the outer packaging  116  in the time interval between the two or more distinct pictures  148  which have been recorded for the same section  150  of the corresponding outer packaging  116 .
