Description

Hinge for security items with improved security and durability and method for detecting counterfeiting using the same

[0001] The present invention relates to a hinge for a security product with improved security and durability and a method for detecting counterfeiting using the same.

[0002] A passport is an official document issued by the government to a person wishing to travel abroad, certifying the traveler's nationality and identity and requesting the other country to protect that person. Typically, when traveling or traveling to another country for business, a passport is issued, authorizing departure. Upon arrival or departure, the passport holder undergoes a required verification process to verify their identity. These passports contain personal information about the holder, including their name, address, nationality, and photograph, as well as other security information.

[0003] Recently, electronic passports that store the aforementioned security information as data have been primarily used. The International Civil Aviation Organization (ICAO) recommends the use of contactless electronic chips (RFID chips) to facilitate the storage and reading of biometric information. However, as issues surrounding the duplication and forgery of security information contained in e-passports have surfaced, illicit duplication of e-passports has become virtually impossible, and various methods for verifying the authenticity of illegally copied e-passports have been studied.

[0004] Examples of security elements include holograms with complex and sophisticated designs, encryption patterns, and laser marking technology that records a unique number or pattern using a laser and then compares it with a database to verify authenticity.

[0005] However, these security elements are typically exposed to the human body for easy identification and readability. Therefore, they are frequently subject to physical and chemical damage from the external environment, and are susceptible to intentional tampering. Furthermore, there is a risk of adverse health effects on passport holders due to the presence of potentially harmful security materials.

[0006] Meanwhile, the data page containing the e-passport holder's identity information is made of plastic with an embedded electronic chip. This plastic material has low flexibility, making it susceptible to damage even from the slightest movement—such as repeatedly folding and unfolding a booklet-style e-passport—which makes the identity information and security elements stored on the data page unidentifiable.

[0007] Accordingly, there is a need for research on a hinge with high durability and excellent security that can minimize contact with the human body while simultaneously providing high security and significantly reduce damage and breakage even when performing repeated folding and unfolding movements.

[0008] The purpose of the present invention is to solve the problems of the above-mentioned prior art, and to provide a hinge for a security product that simultaneously improves durability and security.

[0009] Another object of the present invention is to significantly reduce the area of ​​contact between a security material that has a negative effect on the human body and the user's body.

[0010] Another object of the present invention is to prevent chemical and physical damage and artificial destruction of security elements due to external environments.

[0011] A hinge for a security article according to the present invention comprises a fabric woven with a plurality of weft yarns and a plurality of warp yarns; and a security element containing a fluorescent substance having an emission wavelength when irradiated with excitation light; wherein at least a portion of the fabric comprises a special yarn, and the security element comprises a first security element comprising a security yarn included in at least a portion of the plurality of weft yarns and warp yarns; a second security element comprising a security pattern positioned on the fabric; or a combination thereof.

[0012] In one example, the fluorescent substance may include two or more types of fluorescent substances that emit light by excitation light of different wavelength bands.

[0013] In one example, the fluorescent material may include at least one selected from the group consisting of a first fluorescent material having an emission wavelength by excitation light in the ultraviolet wavelength range; a second fluorescent material having an emission wavelength by excitation light in the infrared wavelength range; and a third fluorescent material having an emission wavelength by excitation light in the visible wavelength range.

[0014] In one example, the fluorescent material may have an emission wavelength in the invisible band.

[0015] In one example, the above-described warp and weft yarns may be woven with security yarns containing different types of fluorescent materials.

[0016] In one example, the weft and warp may comprise different types of fluorescent materials, wherein the weft may comprise a first fluorescent material, a third fluorescent material, or a combination thereof, and the warp may comprise a first fluorescent material, a second fluorescent material, or a combination thereof.

[0017] In one example, the first security element may include 0.05 to 10 parts by weight of a fluorescent material based on 100 parts by weight of the security material.

[0018] In one example, the fluorescent material included in the first security element and the second security element may emit light by excitation light of different wavelength bands.

[0019] In one example, the security pattern can be formed by printing security ink containing a fluorescent substance on a fabric.

[0020] In one example, the special agent may include a high-strength fiber, a reinforcing fiber, or a combination thereof.

[0021] In one example, the high-strength fiber may have a draw ratio of 4 to 10.

[0022] In one example, the reinforcing fiber may include one or more selected from the group consisting of aramid fiber, carbon fiber, and ultra-high molecular weight polyethylene fiber.

[0023] The present invention includes a security article including the hinge for the security article described above.

[0024] A security article according to the present invention comprises a fabric woven with a plurality of weft yarns and a plurality of warp yarns; and a security element containing a fluorescent substance having an emission wavelength when irradiated with excitation light; wherein at least a portion of the fabric comprises a special yarn, and the security element comprises a first security element comprising a security yarn included in at least a portion of the plurality of weft yarns and warp yarns; a second security element comprising a security pattern positioned on the fabric; or a combination thereof.

[0025] In one example, the security item may be an electronic passport.

[0026] The present invention includes a counterfeit detection method and a counterfeit detection device using the above-described hinge for security items.

[0027] The method for detecting counterfeiting according to the present invention comprises the steps of (S10) irradiating the hinge for a security item with excitation light of a first wavelength; (S20) detecting the emission light of a second wavelength emitted from the hinge for the security item; and (S30) determining the authenticity of the security item from the received emission light data.

[0028] In one example, the step (S30) may be to determine authenticity by comparing the emission light data received in the step (S20) with preset reference data.

[0029] In one example, the step (S20) may include: (S21) receiving light emitted from the hinge for the security item; and (S22) detecting light of a second wavelength among the light emitted.

[0030] A counterfeit detection device according to the present invention comprises: a light emitting unit that irradiates the hinge for a security item with excitation light of a first wavelength; a detection unit that detects emission light of a second wavelength emitted from the hinge for a security item; and a determination unit that determines authenticity based on emission light data obtained from the detection unit.

[0031] In one example, the method may further include a display module that displays the result of the determination of authenticity received from the determination unit.

[0032] In one example, the detection unit may include a filter that separates light of a second wavelength from the emitted light.

[0033] The hinge for a security item according to the present invention can simultaneously improve durability and security.

[0034] It can also prevent chemical and physical damage and artificial destruction of security elements due to external environments.

[0035] Furthermore, the area of ​​contact between the user's body and security materials that have a negative effect on the human body can be significantly reduced.

[0043] The present invention provides a detailed description of a hinge for security items with enhanced security and durability, and a method for detecting counterfeiting using the hinge. The terminology used in this specification has been selected from widely used terms, taking into account the functions of the present invention. However, this may vary depending on the intentions of engineers working in the relevant fields, precedents, the emergence of new technologies, etc. Unless otherwise defined, the technical and scientific terms used may have the meaning commonly understood by those of ordinary skill in the technical field to which this invention pertains.

[0044] As used herein and in the appended claims, the singular expression "singular" includes the plural expression unless the context clearly dictates otherwise. Furthermore, the plural expression "singular" includes the singular expression unless the context clearly dictates otherwise.

[0045] In this specification and the appended claims, the terms “include” or “have” mean that a feature or component described in the specification is present, and unless specifically limited, does not preclude the possibility that one or more other features or components may be added.

[0046] In this specification and the appended claims, the terms first, second, etc. are not used in a limiting sense but are used to distinguish one component from another.

[0047] Additionally, the numerical ranges used herein include lower and upper limits and all values ​​within that range, increments logically derived from the shape and width of the defined range, all doubly defined values, and all possible combinations of upper and lower limits of numerical ranges defined in different shapes. Unless otherwise specifically defined in the specification of the present invention, values ​​outside the numerical range that may arise due to experimental error or rounding of values ​​are also included in the defined numerical range.

[0048] The term "about" or the like used in this specification and the appended claims is used to encompass the tolerance when an tolerance exists.

[0049] A hinge for a security article according to the present invention comprises a fabric woven with a plurality of weft yarns and a plurality of warp yarns and a security element containing a fluorescent substance having an emission wavelength when irradiated with excitation light, wherein at least a portion of the fabric comprises a special yarn, and the security element comprises a first security element comprising a security yarn included in at least a portion of the plurality of weft yarns and warp yarns; a second security element comprising a security pattern positioned on the fabric; or a combination thereof.

[0050] Since the hinge of the present invention includes a security element including a security thread containing a fluorescent substance, a security pattern, or a combination thereof, the security is excellent, and at the same time, since the fabric includes a special thread having high elongation and / or high strength properties, the durability is improved, so that the hinge may not be damaged even when folding and unfolding operations are repeated.

[0051] The phosphor may include two or more types of phosphors that emit light when excited by light of different wavelength bands. For example, the phosphor may include two or more types selected from the group consisting of a first phosphor having an emission wavelength when excited by light of an ultraviolet wavelength band; a second phosphor having an emission wavelength when excited by light of an infrared wavelength band; and a third phosphor having an emission wavelength when excited by light of a visible wavelength band. Depending on the type of phosphor, the security element may form a more complex pattern to enhance security.

[0052] The above fluorescent substance is a fluorescent pigment having an emission wavelength in the invisible band when irradiated with excitation light, and thus has low visibility, making it difficult for a user to easily recognize the security element with the naked eye, making counterfeiting difficult and enhancing security.

[0053] In detail, the fluorescent material may include an organic / inorganic compound or an organic polymer having an emission wavelength in the invisible band by excitation light. For example, the first fluorescent material may be Ba 1-X SnAO3(0 <X<0.4, A=Li 또는 Na), Sr3Ga2Ge4O 14 :M(M=Cr 3+ or Yb 3+ ), Y2SiV2O 10 :M(M=Nd 3+ or Er 3+ ) may include a fluorescent material or a combination thereof, and the second fluorescent material may include Y2O3:M (M=Yb, Ho, Tm or Er), LiScSiO4:M (M=Cr 3+ , Yb 3+ ) fluorescent material, NaGdMgWO6:M(M=Cr 3+ , Yb 3+ ) may include a fluorescent material or a combination thereof, and the third fluorescent material may be CaMoO4:M(M= Yb 3+ or Er 3+ ) fluorescent material, Y2SiV2O 10 :M(M=Nd 3+ or Er 3+) may include a fluorescent material or a combination thereof, but the present invention is not limited by the specific type of the fluorescent material.

[0054] The above special material can significantly improve the durability of the hinge for security items and may include high-strength fiber, reinforced fiber, or a combination thereof.

[0055] The high-draw yarn is a fiber having a draw ratio (DR) that is about 15 to 20% higher than that of general yarn. While the draw ratio of general yarn is 3.8 to 4.2, the high-draw yarn refers to a fiber having a draw ratio of 4.0 to 10, 4.3 to 8, or 4.6 to 6. Compared to general fibers, the orientation of the polymer is strengthened, the elongation is maximized, and the tensile strength can be significantly improved. Accordingly, the hinge for a security item of the present invention including the high-draw yarn has the advantage of not being easily damaged even when repeatedly and long-term bent, and of stably maintaining its shape. As a more specific and non-limiting example, the high-draw yarn may include at least one or more of high-draw PET and high-draw nylon.

[0056] The above reinforcing fiber is a fiber having a significantly higher strength than general fibers, and may include at least one selected from the group including aramid fiber, carbon fiber, and ultra-high molecular weight polyethylene fiber.

[0057] Aramid is an aromatic polyamide with a structure in which amide groups are bonded between benzene rings, with more than 85% of the amide groups being directly bonded to the benzene rings. Aramid fibers have the advantages of being lightweight, highly heat-resistant, and highly strong.

[0058] Carbon fiber is a special fiber with high strength and high elasticity with a carbon content of 80%, 85%, or 90% or more. It is easy to process and has the characteristics of high specific strength and elasticity due to its low density.

[0059] Ultra-high molecular weight polyethylene fibers have a high molecular weight of 3,500,000 to 10,500,000 g / mol, and have excellent impact strength and tensile strength, high wear resistance, impact resistance, and self-lubricating properties, as well as strong chemical resistance, weather resistance, and heat resistance.

[0060] As described above, if a hinge for a security item includes a reinforcing fiber having low weight, high strength, chemical resistance, weather resistance, and heat resistance, the security item can be prevented from physical and chemical damage caused by external impact and the external environment even when used for a long period of time.

[0061] In one example, the fiber may further include a general fiber. The general fiber may include a fiber that is conventionally used, and may include at least one selected from the group including polycarbonate (PC), oriented polypropylene (OPP), cast polypropylene (CPP), polyamide (PA), polyacetal, polybutylene terephthalate (PBT), modified polyphenylene oxide (PPO), and fiber reinforced plastic (FRP).

[0062] The fabric may comprise two or more types of fibers selected from the group consisting of a first fiber, a second fiber, and a third fiber. The first fiber, the second fiber, and the third fiber are different from each other, and may each independently comprise one selected from a high-strength yarn, a reinforcing fiber, and a general yarn. A fabric woven by combining a high-strength yarn, a reinforcing fiber, and a general yarn has significantly reduced physical and chemical damage due to external force, and can maintain its original state for a long period of time with excellent resilience even after repeated bending.

[0063] For example, the weft, warp, or a combination thereof may be woven by alternately arranging first fibers and second fibers at regular intervals, or may be woven by arranging a plurality of second fibers at regular intervals between first fibers that are spaced apart from each other. Alternatively, the weft, warp, or a combination thereof may be woven by arranging the first fibers and second fibers at regular intervals, and a third fiber may be positioned between the first fibers and the second fibers. Preferably, positioning the high-stretch yarn in the vertical direction of the tangent line where the hinge folds among the weft and warp yarns is advantageous because it can provide excellent durability even during repeated folding and unfolding operations.

[0064] In one aspect of the present invention, the security element may include security yarns included in at least some of the plurality of wefts and warps. Specifically, the plurality of security yarns included in the fabric may each independently include one or more fluorescent materials selected from the first fluorescent material, the second fluorescent material, and the third fluorescent material, and security yarns including different types of fluorescent materials may be woven into the wefts and warps.

[0065] When the weft and warp include different types of fluorescent materials, not only does the pattern of the first security element become more complex, but the number of cases of patterns that the first security element can form increases exponentially depending on the type, arrangement, and position of the fluorescent material, so there is an advantage in that counterfeiting and tampering are difficult.

[0066] As a more specific example, the weft and warp yarns may contain different types of fluorescent materials, such that the weft yarn may contain a first fluorescent material, a third fluorescent material, or a combination thereof, and the warp yarn may contain a first fluorescent material, a second fluorescent material, or a combination thereof. In the case where the weft and warp yarns contain fluorescent materials that emit light of different wavelength bands, there is an advantage in that the pattern formed by the emission wavelength can be more clearly distinguished when determining counterfeiting as described below.

[0067] Hereinafter, the present invention will be described in detail with reference to the attached drawings.

[0068] Figures 1 to 4 are schematic diagrams showing various weaving forms of first security elements included in a hinge for a security item according to one aspect.

[0069] Specifically, FIG. 1 shows a hinge for a security item according to a first aspect of the present invention, wherein the weft yarn includes a plurality of first security yarns (10) including a first fluorescent substance, and the first security yarns (10) include a first general security yarn (11), a first reinforced security yarn (12), and a first high-elongation security yarn (13) each including a general yarn, a reinforced fiber, and a high-elongation yarn. The warp yarn includes a plurality of second security yarns (20) containing a second fluorescent substance, and the second security yarns include a second general security yarn (21), a second reinforced security yarn (22), and a second high-elongation security yarn (23) each including a general yarn, a reinforced fiber, and a high-elongation yarn. The first reinforced security company (12) and the first high-extension security company (13) were alternately spaced apart, and the first general security company (11) was positioned between the first reinforced security company (12) and the first high-extension security company (13). The second reinforced security company (22) and the second high-extension security company (23) were alternately spaced apart, and the second general security company (21) was positioned between the second reinforced security company (22) and the second high-extension security company (23).

[0070] In the second aspect of the present invention, as illustrated in FIG. 2, the weft yarn is woven in such a way that the first high-elongation security yarn (13) and the first reinforced security yarn (12) are alternately arranged, and the warp yarn is woven in such a way that the second general security yarn (21) and the second high-elongation security yarn (23) are alternately arranged. In the third aspect, as illustrated in FIG. 3, the weft yarn includes a plurality of third security yarns (30) including a third fluorescent substance, and specifically, the third general security yarns (31) and the third high-elongation security yarns (32), each including a general yarn and a high-elongation yarn, are alternately arranged, and the warp yarn is woven in such a way that the first general security yarn (11) and the first reinforced security yarn (13) are alternately arranged.

[0071] According to the fourth aspect, as shown in Fig. 4, the weft is woven in such a way that a plurality of third high-stretch security yarns (32) are arranged between third general security yarns (31) that are spaced apart from each other, and the warp is also woven in such a way that a plurality of first high-stretch security yarns (13) are arranged between first general security yarns (11) that are spaced apart from each other.

[0072] As described above, the first security element can form a variety of patterns depending on the type, location, and arrangement of fibers contained in the fabric woven with weft and warp yarns. The number of patterns that can be formed can increase exponentially by combining patterns formed by the type, location, and arrangement of fluorescent materials with patterns formed by the type, location, and arrangement of fibers. These diverse and complex patterns can themselves be utilized as security elements, enhancing security and making them difficult to replicate, further enhancing the anti-counterfeiting effect.

[0073] In addition, by manufacturing a hinge by arranging two or more types of fibers selected from the group including general fibers, high-strength fibers, and reinforced fibers in the above-described pattern, an external impact applied to a local portion of the hinge can be easily distributed throughout the entire hinge, thereby improving impact resistance and simultaneously improving flexibility and strength, which is advantageous.

[0074] In one example, the method for manufacturing a security thread containing the fluorescent substance may include the steps of (a) adding a fluorescent pigment to a raw plastic and melt-mixing the mixture to produce a mixture; (b) melt-extruding the mixture to produce a master batch; and (c) melting and spinning the master batch to produce a fiber containing the fluorescent substance. The security threads manufactured by the above method can be woven into weft and warp yarns to produce a hinge for a security product according to one aspect of the present invention.

[0075] The raw plastic of the above step (a) may be an appropriate plastic depending on the type of fiber, and for example, the raw plastic may include at least one selected from the group including high-strength PET, high-strength nylon, aramid fiber, carbon fiber, ultra-high molecular weight polyethylene, polycarbonate (PC), oriented polypropylene (OPP), cast polypropylene (CPP), polyamide (PA), polyacetal, polybutylene terephthalate (PBT), modified polyphenylene oxide (PPO), and fiber reinforced plastic (FRP).

[0076] The master batch of step (b) may be in the form of pellets. For example, the average particle size ratio of the pellet particles to the fluorescent particles may be 500 to 50,000:1, 500 to 30,000:1, or 800 to 10,000:1. Since the size of the fluorescent particles is significantly smaller than that of the pellet particles, the fluorescent particles can be uniformly dispersed within the fiber being manufactured.

[0077] In one example, the first security element may contain 0.05 to 10 parts by weight, 0.07 to 8 parts by weight, or 0.1 to 5 parts by weight of the fluorescent agent based on 100 parts by weight of the security yarn. Even if a small amount of the fluorescent agent is added compared to the fiber of the security yarn, an excellent emission wavelength is exhibited, so that the emitted light can be easily detected in the process of determining authenticity described below.

[0078] In another aspect of the present invention, the security element may include a second security element including a security pattern positioned on the fabric.

[0079] Fig. 5 is a schematic diagram illustrating a hinge for a security item including a second security element. As illustrated in Fig. 5, the security pattern is not observed before irradiation with excitation light, but when irradiated with excitation light, the fluorescent substance included in the security pattern exhibits an emission wavelength, allowing for the determination of counterfeiting. As described above, the second security element can prevent the recognition and distribution of the security pattern by adopting a fluorescent substance having an emission wavelength in the invisible band.

[0080] For example, the security pattern may include images, symbols, characters, marks, signs, logos, and other symbols, including shapes, letters, numbers, etc. The second security element forms a more intuitive security pattern than the first security element, so that forgery and tampering can be quickly and accurately determined through the second security element.

[0081] The second security element can be manufactured by printing a security ink containing a fluorescent substance onto a fabric. The security ink may further include a varnish and solvent commonly used in fluorescent-based inks, and, if necessary, may further include one or more additives selected from surfactants, waxes, drying agents, dyes, etc. commonly added to fluorescent-based inks.

[0082] Varnish provides properties such as fluidity and drying properties to ink. A varnish commonly used for ink manufacturing can be used, and a product manufactured by a known method or a commercially available product can be used. For example, the varnish may be a thermoplastic resin, a thermosetting resin, or a photocurable resin, and examples of the thermoplastic resin include petroleum resin, casein, shellac, rosin-modified maleic acid resin, rosin-modified phenolic resin, nitrocellulose, cellulose acetate butyrate, cyclized rubber, chlorinated rubber, oxidized rubber, hydrochloric acid rubber, phenolic resin, alkyd resin, polyester resin, unsaturated polyester resin, amino resin, epoxy resin, vinyl resin, vinyl chloride resin, vinylidene chloride resin, vinyl chloride acetate resin, ethylene vinyl acetate resin, acrylic resin, methacrylic resin, polyurethane resin, silicone resin, fluororesin, drying oil, synthetic drying oil, styrene-maleic acid resin, styrene-acrylic resin, polyamide resin, or butyral resin. Examples of thermosetting resins include pre-oxidized resins, phenol resins, benzoguanamine resins, melamine resins, and urea resins. As photocurable resins (photosensitive resins), a resin can be used that is obtained by reacting a linear polymer having a reactive substituent such as a hydroxyl group, a carboxyl group, or an amino group with a (meth)acrylic compound or cinnamic acid having a reactive substituent such as an isocyanate group, an aldehyde group, or an epoxy group, thereby introducing a photocrosslinkable group such as a (meth)acryloyl group or a styryl group into the linear polymer. In addition, a linear polymer containing an acid anhydride such as a styrene-maleic anhydride copolymer or an α-olefin-maleic anhydride copolymer can be half-esterified with a (meth)acrylic compound having a hydroxyl group such as a hydroxyalkyl (meth)acrylate, but the present invention is not limited thereto.

[0083] Any solvent that can dissolve or disperse the above-described ink components can be used, and is not particularly limited in the present invention. Any solvent that is commonly used in a printing ink composition can be used without particular limitation, and for example, aliphatic hydrocarbons, aromatic hydrocarbons, esters, ketones, alcohols, ethers, etc. can be used. Specific examples of the solvent include aliphatic hydrocarbons such as mineral spirits and kerosene; aromatic hydrocarbons such as benzene, toluene, xylene, and mesitylene; esters such as ethyl 3-ethoxypropionate and methyl 3-methoxypropionate; ketones such as methyl ethyl ketone, acetone, methyl amyl ketone, methyl isobutyl ketone, and cyclohexanone; alcohols such as ethanol, propanol, butanol, hexanol, cyclohexanol, ethylene glycol, and glycerin; Examples thereof include ether-based solvents such as ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, ethylene glycol monobutyl ether, propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monopropyl ether, propylene glycol monobutyl ether, diethylene glycol dimethyl ether, diethylene glycol diethyl ether, diethylene glycol dipropyl ether, diethylene glycol dibutyl ether, methyl cellosolve acetate, ethyl cellosolve acetate, propylene glycol monomethyl ether acetate, propylene glycol monoethyl ether acetate, propylene glycol monopropyl ether acetate, methoxybutyl acetate, and methoxypentyl acetate. The solvents exemplified above may be used alone or in combination of two or more.

[0084] The surfactant is not limited in type, but may include at least one selected from the group consisting of fluorinated surfactants, polymerizable fluorinated surfactants, siloxane surfactants, polymerizable siloxane surfactants, polyoxyethylene surfactants, and derivatives thereof.

[0085] The wax is not limited to a type as long as it is a powder type that has the effect of reducing the tack of the resin, and may include, but is not limited to, one or more selected from, for example, polyethylene wax, amide wax, erucamide wax, polypropylene wax, paraffin wax, Teflon, and carnauba wax.

[0086] Printing of security ink may be done by any method commonly used to apply (print) security ink onto fabric in a designed shape and size, such as inkjet printing, slot-die coating, gravure printing, flexographic printing, doctor blade coating, screen printing, electrostatic hydrodynamic printing, micro-contact printing, imprinting, reverse offset printing, bar coating, gravure offset printing, and roll coating.

[0087] In another aspect of the present invention, as illustrated in FIG. 6, a hinge for a security item may include a first security element and a second security element. That is, a plurality of security threads form a security pattern on a fabric woven with warp and weft yarns, thereby implementing a more sophisticated security pattern, thereby making forgery and falsification very difficult, thereby enhancing security.

[0088] For example, the fluorescent materials included in the first and second security elements may emit light with different wavelength bands. Since the fluorescent materials emit light with different wavelength bands, the first and second security elements can be more clearly distinguished during the counterfeiting detection process described below.

[0089] The present invention includes a security article including the hinge for a security article described above. When describing the security article of the present invention, the materials, structure, shape, size, etc., including fluorescent substances, security elements, and fabrics included in the hinge for a security article are identical or similar to those described above, and therefore, the security article according to the present invention includes all of the above-described hinges for security articles.

[0090] A security article according to the present invention comprises a fabric woven with a plurality of weft yarns and a plurality of warp yarns and a security element containing a fluorescent substance having an emission wavelength when irradiated with excitation light, wherein at least a portion of the fabric includes a special yarn, and the security element comprises a first security element including a security yarn included in at least a portion of the plurality of weft yarns and warp yarns; a second security element including a security pattern positioned on the fabric; or a hinge for a security article including a combination thereof.

[0091] The above security item may be a booklet-type security document including an ID card, passport, identification card, banknote, securities, gift certificate, tax payment certificate (stamp), etc., and more specifically, may be an electronic passport.

[0092] In one example, FIG. 7 is a schematic diagram illustrating a data page (101) including a hinge (102) for a security item. As illustrated in FIG. 7, the data page (101) of a passport includes personal information for identification purposes such as the owner's name, photo, and address, and therefore requires high security to prevent forgery. The data page (101) is composed of multiple layers, including an IC chip, an IC chip receiving layer, a personal information layer printed with the owner's identification information, a security element layer, and a protective layer, and is made of a plastic material such as polycarbonate (PC), so it has low flexibility, and when the data page (101) is combined with an electronic passport and a booklet-type product, it can be easily damaged when repeated folding and unfolding operations are performed.

[0093] By applying a security item hinge (102) to the above data page (101), the data page (101) is not damaged even with repeated folding and unfolding operations, thereby improving durability, and at the same time, forgery and alteration of the electronic passport can be prevented and security can be further improved by the security element included in the security item hinge (102).

[0094] The above hinge (102) may be arranged to be connected in parallel with the data page (101) and protrude in one direction of the data page (101), or the hinge (102) may be partially inserted into the data page (101) and the remaining portion may be arranged to protrude in one direction of the data page (101).

[0095] In one example, FIG. 7 is a front view illustrating an electronic passport (200) including a hinge (102) for a security item. Referring to FIG. 7, the electronic passport (200) may include a cover (202), an inner portion (201) located inside the cover (202), a data page (101) located between the inner portion (201) and the cover (202), and a hinge (102) for a security item located at the center of the electronic passport (200) connected to the data page (101). The hinge (102) for a security item, the inner portion (201), the cover (202), and the data page (101) may be sewn together by a special sewing thread (203).

[0096] The security item hinge (102) connects the data page (101) and the inner surface (201). Since it is located on the inner center of the electronic passport (200), it significantly reduces the probability of exposure to the human body and prevents physical and chemical damage from the external environment. In addition, it prevents the migration of security materials such as fluorescent substances, thereby continuously maintaining product quality.

[0097] The present invention includes a counterfeit detection method and a counterfeit detection device using the aforementioned hinge for security items. Since the hinge for security items is identical to that described above, a detailed description thereof will be omitted.

[0098] Fig. 8 is a flowchart illustrating a counterfeit detection method of the present invention. As illustrated in Fig. 8, the counterfeit detection method according to the present invention includes: (S10) a step of irradiating the hinge for a security item with excitation light of a first wavelength; (S20) a step of detecting an emission light of a second wavelength emitted from the hinge for a security item; and (S30) a step of determining whether the security item is genuine or fake based on the received emission light data.

[0099] The first wavelength and the second wavelength may be any one wavelength value, or may refer to a wavelength band within a predetermined range. Specifically, the first wavelength may be light in the ultraviolet, visible, or infrared bands, and the second wavelength may be light in the invisible band.

[0100] In one example, the step (S20) may include detecting light of a second wavelength among the emitted light emitted from the hinge, (S21) receiving the emitted light from the hinge for the security item; and (S22) detecting light of a second wavelength band among the emitted light.

[0101] When detecting the second wavelength light among the emitted light by filtering the second wavelength light when receiving the emitted light, steps (S21) and (S22) are performed simultaneously, so that the second wavelength light can be easily separated from the emitted light through a simpler process.

[0102] Alternatively, when steps (S21) and (S22) are performed sequentially, after receiving the emission light, the spectrum of the received emission light can be data processed to detect the light of the second wavelength included in the emission light.

[0103] In one example, the above steps (S10) and (S20) may be performed as unit processes, and the unit processes may be performed two or more times. Since the security elements included in the hinge for a security item emit light by excitation light of different wavelength bands, the wavelength band of the first wavelength may be changed for each unit process, so that the emitted light of the first security element and the second security element included in the hinge for a security item can be easily detected.

[0104] Step (S30) may be performed through a recognition algorithm, and for example, the authenticity may be determined by comparing the emission data received in step (S20) with preset reference data. The pre-stored reference data may be the peak height of the second wavelength. For example, if the preset reference data value and the peak value of the second wavelength are compared and the peak value of the second wavelength is detected to be a value greater than the reference data value, the product may be determined to be authentic.

[0105] If the second wavelength has a wavelength band of a predetermined range, the reference data may be the sum of the emission intensity of the second wavelength band. The sum of the emission intensity can be determined as genuine if the integrated value of the intensity of the second wavelength band within the wavelength range determined as the reference data is greater than or equal to a threshold value. Alternatively, the authenticity can be determined by comparing parameters related to the luminescence lifetime, such as the rate at which the emission intensity of the second wavelength band decreases and the decay time, with the reference data.

[0106] The present invention includes a counterfeit detection device using the hinge for a security item described above.

[0107] As illustrated in FIG. 9, a counterfeit detection device (300) according to the present invention includes a light emitting unit (301) that irradiates a first wavelength of excitation light to the hinge for a security item described above; a detection unit (302) that detects an emission light of a second wavelength emitted from the hinge for a security item; and a determination unit (303) that determines authenticity based on the emission light data obtained from the detection unit (302).

[0108] The above light-emitting unit (301) includes a light source capable of irradiating infrared, visible, or ultraviolet light wavelength bands onto a hinge for a security item. The light source may include a lamp or an LED, but the present invention is not limited to the specific type of the light source.

[0109] The detection unit (302) receives the emitted light and detects the light of the second wavelength included in the emitted light, and may include an image capturing device or a light sensor, and preferably may include a light sensor.

[0110] The above-mentioned optical sensor may be a photodiode. The photodiode absorbs different wavelength bands depending on the material. For example, silicon (Si) absorbs light in the wavelength band of 190 to 1100 nm, indium gallium arsenide (InGaAs) absorbs light in the wavelength band of 800 to 2600 nm, and germanium (Ge) can absorb light in the wavelength band of 800 to 1700 nm. Accordingly, the material of the photodiode can be appropriately selected depending on the type of fluorescent substance to easily detect the emitted light of the second wavelength. For example, when the emitted light of the second wavelength emitted from the hinge for security items is light in the infrared wavelength band, the emitted light can be effectively detected by adopting a photodiode including germanium (Ge) or indium gallium arsenide (InGaAs).

[0111] The above detection unit (302) may include a filter that separates the second wavelength light included in the emitted light emitted from the hinge for security items. The emitted light received by the detection unit (302) can pass through the filter to transmit only the second wavelength light, so that the second wavelength light can be detected through a simple process without the need for separate data processing of the emitted light. For example, the filter may be a band-pass filter.

[0112] The determination unit (303) can determine the authenticity of a security item based on the emission data obtained from the detection unit (302), including a memory in which reference data is stored and a calculation circuit for performing a comparison operation with the reference data. Specifically, as described above, the authenticity can be determined by comparing the emission data with previously input reference data such as the peak height and intensity of the second wavelength, the sum of the luminescence intensities of the second wavelength having a predetermined wavelength band, and the decay time.

[0113] The control unit (304) can control the operation of each device included in the counterfeit detection device (300). The control unit (304) can control the ON / OFF operation of the light emitting unit (301), control the emission light detection operation of the detection unit (302) in conjunction with the ON / OFF operation of the light emitting unit (301), and can also control the operation of displaying the authentication result of the display module described below.

[0114] The above-described counterfeit detection device (300) may further include a display module (not shown) that displays the authenticity determination result received from the determination unit (303). The display module may include a light source such as an LED, a speaker, a vibrator, or a combination thereof, and generates light, an alarm sound, vibration, etc. according to the authenticity determination result, thereby easily confirming whether the product is counterfeit even in a public place with many users, such as an airport. The display module may be included in the control unit (304) or may exist as a separate device.

[0115] The counterfeiting determination device (300) may display the counterfeiting determination result by itself through the above display module, or the counterfeiting determination device (300) may further include a communication unit (not shown) to transmit and store the authenticity determination result of the determination unit (303) to a separate server, and the server that receives the authenticity determination result may display the counterfeiting determination result.

[0116] The above communication unit can easily collect and utilize counterfeit detection results by linking the counterfeit detection device (300) with a computer, mobile phone, or dedicated terminal, including a wired or wireless communication device such as Bluetooth or Wi-Fi. For example, there is an advantage in that the distribution of counterfeit security items can be tracked using counterfeit detection result data continuously collected through the communication unit.

[0117] As described above, the present invention has been described with specific details and limited examples and drawings, but these are provided only to help a more general understanding of the present invention, and the present invention is not limited to the above examples, and those skilled in the art to which the present invention pertains can make various modifications and variations based on this description.

[0118] Therefore, the idea of ​​the present invention should not be limited to the described embodiments, and all things that are equivalent or equivalent to the following claims as well as the claims are considered to fall within the scope of the idea of ​​the present invention.
