Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to an identification feature composite structure. Background Art

[0002] The production of composite paper materials requires special manufacturing equipment, processes and materials. Some products made of composite paper materials will also have a high manufacturing cost, and it is difficult or too costly to make copies of these products. Based on this characteristic of composite paper materials and their printed products, some commodities with paper packaging can be packaged using this material product; or, some important information can be carried by composite paper material products to distinguish them from other ordinary items. However, with the rapid development of science and technology, the technology of materials and manufacturing processes has also developed rapidly. A single technical means can also produce composite paper materials with relatively simple structures and identification features. Manufacturing composite paper materials and their products is no longer a very difficult or costly operation. The demand for composite paper material products will become more and more widespread and common, making general composite paper material products no longer have the expected degree of differentiation. Therefore, the technical problem that needs to be solved by those skilled in the art is to design a product structure with higher differentiation and difficult to make copies of. Summary of the invention

[0003] In order to solve the above technical problem or at least partially solve the above technical problem, the present invention provides an identification feature composite structure.

[0004] In a first aspect, a composite structure of identification features is provided, comprising a substrate layer, a second identification feature body, a graphic area, and a password information area. The substrate layer contains a plurality of first identification feature carriers and forms a disordered pattern on the surface of the substrate layer; the second identification feature body has a predetermined width, and at least a portion of the second identification feature body is embedded in the substrate layer; the graphic area is arranged on the surface of the second identification feature body, and the graphic area includes a graphic combination of recorded data symbol information arranged according to a predetermined rule, and the graphic combination can be read and recognized by an image input device or an optoelectronic scanning device; the password information area is provided with password information.

[0005] In a first possible implementation manner, the password information area is arranged on the surface of the second identification feature body and is adjacent to the graphic area.

[0006] In combination with the above possible implementation manners, in a second possible implementation manner, there are multiple graphic areas and multiple password information areas, and the two areas are arranged at intervals from each other.

[0007] In combination with the above possible implementations, in a third possible implementation, a graphic area and an adjacent password information area are defined as an identification unit, and when a partial segment of the second identification feature body is embedded in the base layer, at least one identification unit is exposed outside the second identification feature body.

[0008] In combination with the above possible implementations, in a fourth possible implementation, when the second identification feature is completely embedded in the base layer, the structural portion of the base layer covering the second identification feature is configured to be non-adhesive to the surface of the second identification feature and to be separable from the base layer along a preset trajectory.

[0009] In combination with the above possible implementations, in a fifth possible implementation, a plurality of first identification feature carriers are randomly distributed in the base layer.

[0010] In combination with the foregoing possible implementations, in a sixth possible implementation, the first identification feature carrier is a sheet-like structure.

[0011] In combination with the foregoing possible implementations, in a seventh possible implementation, a plurality of first identification feature carriers are randomly arranged in a thickness direction of the base layer.

[0012] In combination with the foregoing possible implementations, in an eighth possible implementation, surfaces of some of the plurality of first identification feature carriers are exposed outside the base layer.

[0013] In combination with the above possible implementations, in a ninth possible implementation, the graphic combination in the graphic area is a two-dimensional code graphic, a barcode, or an encrypted number.

[0014] In combination with the foregoing possible implementations, in a tenth possible implementation, the second identification feature body is a strip-shaped thin sheet.

[0015] In combination with the foregoing possible implementations, in an eleventh possible implementation, the second identification feature body contains a magnetic material, a metal material, a thermosensitive material, a fluorescent material, a diffraction image surface or a holographic image surface.

[0016] The above technical solution provided by the embodiment of the present application has the following advantages over the prior art: the multiple first identification feature carriers in the base layer can form a disordered pattern with a unique arrangement relationship on the surface of the base layer, and the first identification feature carrier can also be separated from the base layer, so it is impossible to make a copy with the above structure. Moreover, the second identification feature body with a larger width embedded in the base layer is combined to further increase the difficulty of the manufacturing process. The setting of the graphic area and the password information area can also facilitate the user to obtain the verification information corresponding to the above identification features through general equipment or special equipment.

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

[0027] The identification feature composite structure provided by the present invention comprises a base layer containing a first identification feature carrier, a second identification feature body, a graphic area and a password information area. The first identification feature carrier forms a disordered pattern on the surface of the base layer; the second identification feature body has a predetermined length, width and thickness, and at least a part of the second identification feature body is embedded in the base layer; the graphic area is arranged on the surface of the second identification feature body, and the graphic area includes a graphic combination of recorded data symbol information arranged according to a predetermined rule, and the graphic combination can be read and recognized by an image input device or an optoelectronic scanning device; the password information area contains password information.

[0028] The graphic combination in the graphic area can be read by a general or special device, and the data symbol information recorded by the graphic combination can be obtained, which can be a channel for further obtaining the required information. After obtaining the password information recorded in the password information area, the password information can be input through the aforementioned channel to obtain the unique identification feature information corresponding to the password information. The unique identification feature information can be the image information of the disordered pattern formed on the surface of the substrate layer obtained and stored in advance, so that it is possible to visually compare the disordered pattern on the surface of the identification feature composite structure with the unique identification feature information to see if it is consistent.

[0029] refer to Figures 1 to 3 , Figure 1 is a schematic diagram of a composite structure of identification features in one embodiment of the present invention, Figure 2 for Figure 1 A schematic diagram of the first identification feature carrier 10, Figure 3 It is a schematic diagram of the distribution of the first identification feature carrier 10 in the base layer 100.

[0030] In this embodiment, the identification feature composite structure includes a base layer 100, a second identification feature body 200, a graphic area 300, a first password information area 410 and a second password information area 420, and the base layer 100 contains a plurality of first identification feature carriers 10. The base layer 100 is a paper base, which can be produced by a papermaking device, and has a certain thickness and strength. The first identification feature carrier 10 is a hexagonal sheet structure, which is randomly scattered in the base layer 100 and is integrated with the base layer 100. In the production process of the base layer 100, the first identification feature carrier 10 is added to the raw material and shaped and dried to obtain the base layer 100 containing the first identification feature carrier 10. The second identification feature body 200 is a strip-shaped thin sheet, which is also fixed inside the base layer 100 during the production process of the base layer 100 and exposes one surface to the outside of the base layer 100. A plurality of first password information areas 410 and second password information areas 420 are arranged on the surface of the second identification feature 200, and both are also exposed outside the base layer 100. The above structure will be further explained below.

[0031] The base layer 100 is a paper product with a fiber structure and can be made of pulp. The pulp flows continuously onto a round screen or a fourdrinier through a sizing device, and the pulp is gradually dehydrated on the screen to form a wet web, which is then dehydrated by a roller press. Only part of the moisture on the paper web can be removed by mechanical pressure, and it needs to be dried by a drying cylinder later. The base layer 100 can be a single-layer structure or a multi-layer structure. When the base layer 100 is a multi-layer structure, the fiber length or arrangement of each layer may be different.

[0032] During the manufacturing process of the base layer 100, the first identification feature carrier 10 can be mixed into the raw material pulp in advance, and a plurality of first identification feature carriers 10 can be randomly distributed in the finally formed base layer 100. Figure 2 , Figure 2 for Figure 1 Schematic diagram of the first identification feature carrier 10. The first identification feature carrier 10 is a hexagonal sheet structure, having an upper surface 11 and a lower surface 12. The base layer 100 itself has a certain degree of perspective, and the first identification feature carriers 10 distributed in the base layer 100 can be observed / photographed more or less.

[0033] Since the first identification feature carrier 10 is randomly distributed in the base layer 100, each first identification feature carrier 10 has a unique orientation in the base layer 100, and the positional relationship between any two first identification feature carriers 10 is also different, thereby forming a unique pattern that can be visually observed and photographed. In addition, the first identification feature carrier 10 is an object independent of the base layer 100 and can be separated from the base layer 100. The unique pattern can be copied by photocopying, but the area representing the first identification feature carrier 10 cannot be separated from the copied pattern. The manufacturing material of the first identification feature carrier 10 can be paper, plastic, metal or composite material with a fiber structure, and the first identification feature carrier 10 can have a completely consistent shape and thickness, or have certain differences.

[0034] refer to Figure 3 , Figure 3Schematic diagram of the distribution of the first identification feature carrier in the base layer 100. The base layer 100 includes a plurality of first identification feature carriers, and the directional positional relationship between the plurality of first identification feature carriers and the surface of the base layer 100 is different. The first identification feature carrier 10a is completely inside the base layer 100, and the upper surface of the first identification feature carrier 10a and the surface of the base layer 100 have an angle of about 15 degrees. The first identification feature carrier 10b is parallel to the upper surface of the base layer 100 and one of its surfaces is flush with the upper surface of the base layer 100. The first identification feature carrier 10c is also completely inside the base layer 100, but it is farther from the upper surface of the base layer 100 than the first identification feature carrier 10a. Due to the above reasons, the first identification feature carriers 10a, 10b and 10c can present different visual effects on the surface of the base layer 100, with different color depth, transparency and visibility, and can form complex and more random and unique patterns. The first representation characteristic carrier may be arranged in a disordered manner across the width direction of the base layer, or may be arranged in a disordered manner within a predetermined width and a predetermined position range.

[0035] The second identification feature 200 is in the shape of a strip, with a thickness of less than 0.02 mm and a width of more than 5 mm. In this embodiment, the width of the second identification feature 200 is 6 mm and the thickness is 0.01 mm. The numerical values ​​here are used for illustration, not limitation. The length of the second identification feature 200 is equal to the width of the base layer 100, and the segments at both ends of the second identification feature 200 are completely below the surface of the base layer 100, and the middle segment is not covered by the tissue of the base layer 100. Figure 1 The portion indicated by the dotted line on the second identification feature 200 is the portion hidden in the base layer 100 .

[0036] In this embodiment, the second identification feature 200 is a thin strip made of a metal material, which has a certain strength and surface gloss. The second identification feature 200 is added by a special process during the manufacturing process of the base layer 100, and part of its band segment is completely located inside the base layer 100, and one surface of the other part of the band segment is exposed on the surface of the base layer 100. In some optional embodiments, the structure of the second identification feature 200 may also include a magnetic material, a thermosensitive material, a fluorescent material, a diffraction image surface or a holographic image surface.

[0037] The graphic area 300 is a rectangular area printed on the surface of the second identification feature body 200. The graphic combination of the recorded data symbol information arranged according to a predetermined rule is arranged in the graphic area. In this embodiment, the graphic combination is a two-dimensional bar code such as a Quick Response Code. The two-dimensional code can be a graphic obtained by encoding according to the two-dimensional code grid matrix code standard (SJ / T 11349-2006) or the international standard (ISO / IEC 18004: 2000 "Automatic Identification and Data Collection Technology - Bar Code Symbol Technical Specification - QR Code").

[0038] The graphic combination can be read and the data symbol information can be recognized by an image input device or an optoelectronic scanning device, such as using the scan function in WeChat on a mobile phone to scan the graphic area 300. Of course, the scan function in Alipay software or other general dedicated applications can also be used to scan the graphic area 300.

[0039] The data symbol information recorded in the graphic area 300 can be recognized by the application program and output predefined information, such as jumping to a predetermined website. In some optional embodiments, the data symbol information recorded in the graphic area 300 can also be time-sensitive information, or can be information that can only be read a limited number of times. In some optional embodiments, the combination set in the graphic area 300 can also be a barcode, encrypted number, personalized graphic, pattern, text, number, letter, etc.

[0040] The first password information area 410 and the second password information area 420 are also arranged on the surface of the second identification feature body 200 and are adjacent to the graphic area 300. The first password information area 410 contains password information, which can be a key for extracting predetermined information. For example, after scanning the graphic area 300, the website jumped to can be entered on the website, and the character string recorded in the first password information area 410 can be entered on the website to obtain the predetermined information from the website. Specifically, the predetermined information can be an electronic picture of the pattern formed by the first identification feature carrier 10 on the substrate layer 100. After obtaining the electronic picture, the picture can be compared with the pattern on the surface of the substrate layer 100 to determine whether they are consistent. The second password information area 420 can be printed with instructions for use or prompt information, or when multiple verifications are required on the website, the second password information area 420 is set with a second key.

[0041] In some optional embodiments, after scanning the graphic area 300 using an application, a user may be redirected to a set website, where a query bar is provided. After the password information recorded in the first password information area 410 is input into the query bar on the website, the preset verification information corresponding to the password information may be extracted. If the same password information is input into the query bar for another query, the preset verification information may be extracted, and a prompt message may be output, such as "This key 851a9_3m8 is the second query."

[0042] In some optional embodiments, only the first password information area 410 may be provided, and the second password information area 420 may not be provided.

[0043] like Figure 1 As shown, the length of the second identification feature 200 is equal to the width of the base layer 100, and the second identification feature 200 includes two identification units formed by the combination of a graphic area and a password information area, one identification unit is the graphic area 300, the first password information area 410 and the second password information area 420, and the other identification unit is the graphic area 300a, the first password information area 410a and the second password information area 420a. The graphic area 300a, the first password information area 410a and the second password information area 420a are located inside the base layer 100.

[0044] In this embodiment, the identification feature composite structure shown in the figure is a local structure obtained after cutting.

[0045] In some optional embodiments, the base layer 100 may have a larger width, and the second identification feature 200 may also be provided with more identification units. There are multiple identification units on the second identification feature 200 exposed on the surface of the base layer 100, and the exposed identification units may be adjacent identification units or may be spaced. For example, when the first identification unit is exposed, the second identification unit is hidden, the third identification unit is exposed, the fourth identification unit is hidden... and so on. Alternatively, the length of the area on the base layer 100 where the identification unit can be exposed is the length occupied by the two identification units, so that the two adjacent identification units can be exposed outside the base layer 100. For example, the area on the base layer exposed for the exposed part of the identification unit is 20 mm, and the area contained in the paper is 5 mm. The size of the identification unit can be of various types, so one or more identification units may be exposed in the 20 mm exposed part area. In addition, the cumulative length error of the second identification feature 200 caused by stretching during the production process will also cause different exposed parts on the base layer. Therefore, the pattern of the exposed identification elements on the base layer is not necessarily the same.

[0046] In other optional embodiments, the second identification feature 200 is completely embedded in the base layer 100, and the structural portion of the base layer 100 covering the surface of the second identification feature 200 is configured to be non-adhesive to the surface of the second identification feature 200 and can be separated from the base layer along a preset trajectory. In other words, the surface of the second identification feature 200 is covered with a layer of easily torn structure, and the structure is a part of the base layer 100, and is integrally formed with the base layer 100, rather than being attached to the base layer 100 by means of bonding or the like.

[0047] In some optional embodiments, the password information area is not disposed on the surface of the second identification feature 200, but is printed on the surface of the base layer 100 and is adjacent to the graphic area 300. Compared with the structure in which the password information area is disposed on the second identification feature 200, the process difficulty of directly disposing the password information area on the surface of the base layer 100 is lower.

[0048] In some optional embodiments, the arrangement of multiple first identification feature carriers 10 can also be set according to predefined rules, and the arrangement form of the first identification feature carriers 10 set according to the rules will not be repeated, and the graphic combination formed by the multiple first identification feature carriers 10 on the surface of the base layer 100 is also unique.

[0049] In some optional embodiments, the first identification feature carrier 10 can also be in other shapes, such as rectangle, triangle, square, rectangle and other polygons, circle, fiber, micro-dot, etc. The base layer 100 can be provided with a carrier of one shape, or a plurality of carriers of multiple shapes, such as only a quadrilateral carrier, or a mixture of triangles and quadrilaterals. In other optional embodiments, the first identification feature carrier 10 can also be irregular fiber, circle, triangle, quadrilateral or pentagon and other polygons, or powder, particles, sphere, cube or other irregular cube, or irregular styles such as "S", "Y", "W". The material of the first identification feature 10 can be 30-40 grams of thin paper, or 8-30μm PET film.

[0050] In the above structure, the first identification feature carrier 10 randomly distributed or distributed according to a predetermined rule can form a unique pattern on the surface of the base layer 100, and a copy of the pattern can only be obtained by copying. In addition, since the first identification feature carrier 10 is embedded in the base layer 100 and is tightly combined with the base layer 100 and can also be separated from the base layer 100, the copied pattern cannot be separated. Therefore, once manufactured, the identification feature composite structure cannot obtain an identical copy. The process of embedding the second identification feature 200 in the base layer 100 is also very difficult and has a high manufacturing threshold. The process of making a second identification feature 200 with a larger width and setting a graphic area 300 on its surface is also complicated. The structure combining the above identification features is difficult to manufacture and cannot be copied.

[0051] refer to Figures 4 to 6 , showing Figure 4 FIG. 2 is a front view of a second identification feature 200b in another embodiment of the present invention. Figure 5 for Figure 4 A perspective view of the second identification feature 200b, Figure 6 To contain Figure 4 Schematic diagram of the identification feature composite structure 500b of the second identification feature body 200b.

[0052] The second identification feature body 200b is a strip-shaped sheet of PET material, with a width range of 3 to 15 mm, preferably 5.5 to 9 mm; a thickness of 8 to 30 μm, preferably 10 to 20 μm; and a material of a transparent or opaque PET film or a PET film containing a laser hologram. A two-dimensional code is printed on the graphic area 300b on the surface of the PET film, and a password is printed on the first password information area 410b. Part of the second identification feature body 200b is embedded in the substrate layer, such as the area in the dotted box in the figure; part of the second identification feature body 200b is exposed to the outside, such as the hidden area 500b on both sides of the dotted box in the figure. On one side of the second identification feature body 200b, a first identification feature carrier 10d is also provided, which is added by directional application. Identification feature carriers of various shapes form a strip area and form an information combination with the two-dimensional code. During production, a fixed collection area is printed or marked according to the position of the printed matter. During the detection stage, the first feature identifier within the fixed collection area is photographed, stored and assigned a value. During use, the image information within the fixed area of ​​the first feature is retrieved and compared by collecting the QR code or random pattern of the second feature.

[0053] Image acquisition technology and auxiliary hardware equipment can identify QR codes and take pictures of images within the variable area, and automatically establish a correspondence between the QR code and the first identification feature carrier through the Internet software system. All captured QR codes and images of the first identification feature carrier are stored in the database, or a corresponding relationship is established in the form of a computer algorithm without setting up a database. When querying, different query content and results can be obtained using social general software and customized special software. Social general software such as WeChat is mainly used for consumer queries. Special software should be able to be used in factories in various stages of printed production, such as paper mills, printing plants, processing plants, etc., to manage industrial production through such content.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
