発明の効果  The invention's effect
[0013] 本発明によると、検出された対象物蛍光スペクトルが、予め設定された有限種類の 真正な情報提示物質が呈する個別蛍光スペクトルの組み合わせによって再現される か否力から対象物の真贋を判定するため、仮に第三者によって真正品に近似した蛍 光スペクトルを呈する偽物が作製されても、これを識別することができ、真贋判断の高 V、信頼性を確保することができる。  [0013] According to the present invention, the authenticity of an object is determined based on whether or not the detected fluorescence spectrum of the object is reproduced by a combination of individual fluorescence spectra of predetermined finite types of authentic information presenting substances. Therefore, even if a third party produces a fake exhibiting a fluorescence spectrum similar to that of a genuine product, this can be identified, and high V and reliability of authenticity determination can be ensured.
[0014] また、有限種類の真正な情報提示物質の組み合わせに検討範囲を限定できるた め、真贋判定に要する計算負荷を小さくすることができる。 [0014] In addition, the scope of the study can be limited to a combination of finite types of genuine information presenting substances. Therefore, the calculation load required for authenticity determination can be reduced.
[0015] なお、第三者によって対象物力 蛍光スペクトルが検出されたとしても、蛍光を放射 する物質には無限に近い種類があるため、検出された蛍光スペクトルを構成している 真正な情報提示物質を特定することは事実上不可能である。  [0015] Even if the fluorescence spectrum of an object is detected by a third party, since there are almost infinite types of substances that emit fluorescence, the genuine information presenting substance that constitutes the detected fluorescence spectrum It is virtually impossible to specify
[0016] また、真正な情報提示物質の相対的な配合比率も有限種類にすると、情報提示物 質の組み合わせ検討範囲をさらに限定できるため、真贋判定の計算負荷をさらに小 さくすることができる。 [0016] Furthermore, if the relative blending ratio of the genuine information presenting substances is also limited, the range for examining the combinations of the information presenting substances can be further limited, so that the calculation load for authenticity determination can be further reduced.
[0017] また、情報提示物質の組み合わせに対応づけられた対象物に関する情報を出力 するようにすると、対象物の真贋判定結果に加えて、その対象物に関する情報も得る ことができる。  [0017] Further, by outputting information on an object associated with a combination of information presenting substances, it is possible to obtain information on the object in addition to the result of authenticity determination of the object.
[0018] また、対象物の真贋判定を行う真贋判定システムを、対象物から蛍光スペクトルを 検出する検出装置端末と、この蛍光スペクトル力 対象物の真贋判定を行うサーバと を含む構成にすると、真正な情報提示物質に関する情報をサーバにおいて一元管 理することができ、これにより真正な情報提示物質に関する情報の秘匿性を高めて 偽造のおそれをさらに軽減することができる。  [0018] Furthermore, when the authentication system for determining the authenticity of an object includes a detection device terminal for detecting a fluorescence spectrum from the object and a server for determining the authenticity of the fluorescence spectrum, the authenticity of the object can be improved. It is possible to centrally manage information relating to the information presenting substance in the server, thereby increasing the confidentiality of the information relating to the authentic information presenting substance and further reducing the risk of forgery.

[0025] [情報提示物質]  [0025] [Information Presentation Material]
情報提示物質は、特定の波長領域の電磁波 (たとえば所定波長領域の紫外線)の 照射に対して、所定の蛍光を放射する一種もしくは二種以上の元素、二種以上の元 素の化合物、またはそれらの元素もしくは化合物を含む物質力もなる。この蛍光は、 外部からの電磁波の照射によって、情報提示物質のイオンが基底準位力 エネルギ 一の高い準位に励起され、その後エネルギーの低い準位に遷移することによって放 射される。情報提示物質は、その種類により特有の蛍光のスペクトル分布を放射する  The information-presenting substance is one or more elements, two or more compounds, or a compound of two or more elements that emit predetermined fluorescence when irradiated with electromagnetic waves in a specific wavelength range (for example, ultraviolet rays in a predetermined wavelength range). Material containing the element or compound of This fluorescence is emitted when the ions of the information presenting substance are excited to a level having a high ground level force and then to a level having a low energy by irradiation of an external electromagnetic wave. The information presenting substance emits a specific fluorescence spectrum distribution depending on its type.
[0026] 情報提示物質は、各種プラスチック、塗料、インク、紙、繊維または金属など、汎用 の各種材料に対して一般に含有されて 、な 、元素または化合物 (酸化物、硫化物、 有機錯体など)を含むものであることが好ましい。汎用の各種材料に対して一般に含 有されていない元素としては、原子番号 31から原子番号 88までの元素、好ましくは ランタノイド系元素、さらに好ましくはセリウム (Ce)、プラセオジム (Pr)、ネオジム (Nd )、プロメチウム（Pm)、サマリウム（Sm)、ユーロピウム（Eu)、ガドリニウム（Gd)、テル ビゥム（Tb)、ジスプロシウム (Dy)、ホルミウム（Ho)、エルビウム（Er)、ツリウム（Tm) 、イッテルビウム (Yb)を挙げることができる。 [0026] The information presenting substance is generally contained in various general-purpose materials such as various plastics, paints, inks, papers, fibers, and metals, and is composed of elements or compounds (oxides, sulfides, organic complexes, etc.). It is preferable that it contains. Elements that are not generally contained in various general-purpose materials include elements having atomic numbers 31 to 88, preferably lanthanoid elements, more preferably cerium (Ce), praseodymium (Pr), and neodymium (Nd ), Promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium ( Yb).
これらの元素は、スペクトル分析による測定が容易であり、さらに経済的かつ衛生的 で、酸ィ匕物等としての入手も容易であるため、情報提示物質としては、これら元素の 一種または二種以上が組み合せたものが好適である。なお、情報提示物質としては 、同じ元素を含むものであっても組み合わせられる他の元素の種類や、組み合わせ の比率が異なれば、別の情報提示物質として扱うことができる。  Since these elements are easy to measure by spectral analysis, are more economical and sanitary, and are easily available as oxidants, etc., one or more of these elements may be used as an information presenting substance. Are preferably combined. It should be noted that the information presenting substance can be treated as another information presenting substance, even if it contains the same element, if the types of other elements to be combined and the ratio of the combination are different.
[0027] また、情報提示物質は、赤外光から紫外光までの蛍光を利用する場合は、不完全 3d殻を有する遷移元素および Zまたは不完全 4f殻を有する遷移元素が添加された 単結晶や、不完全 3d殻を有する遷移元素および Zまたは不完全 4f殻を有する遷移 元素が添加されたガラスや、不完全 3d殻を有する遷移元素および Zまたは不完全 4 f殻を有する遷移元素を中心とした錯体などが、高い蛍光強度が得られるため、好適 である。 [0027] In addition, when utilizing the fluorescence from infrared light to ultraviolet light, a transition element having an incomplete 3d shell and a transition element having Z or an incomplete 4f shell are added to the information presenting substance. Single crystal, glass to which a transition element having an incomplete 3d shell and a transition element having a Z or incomplete 4f shell are added, or a transition element having an incomplete 3d shell and a transition element having a Z or incomplete 4f shell A complex centered on is preferred since a high fluorescence intensity can be obtained.
[0028] また、情報提示物質は、ユーロピウム (Eu3+)を含む酸化イットリウム (Y O )のように [0028] In addition, the information presenting substance is, for example, yttrium oxide (YO) containing europium (Eu 3+ ).
2 3 twenty three
、所定の母体物質に対して遷移元素を付与したものであってもよい。この母体物質は 、酸化物、硫化物、窒化物、水酸化物、ハロゲンィヒ物、混晶、さらにはアモルファス物 質、ガラスなども含まれる。たとえば、遷移元素がキレートイ匕合物のように化学結合の 形で含まれて 、るもの、結晶格子を構成する他の原子またはイオンを置換したもの、 結晶格子の中に割り込んで含まれるもの、あるいはガラスの中の隙間に含まれるもの などが挙げられる。 Alternatively, a transition material may be added to a predetermined base substance. The host substance includes oxides, sulfides, nitrides, hydroxides, halogen compounds, mixed crystals, amorphous substances, and glass. For example, those in which the transition element is contained in the form of a chemical bond, such as a chelating compound, those in which other atoms or ions constituting the crystal lattice are substituted, those in which the transition element is included in the crystal lattice, Alternatively, a material included in a gap in the glass may be used.
[0029] 特に無機酸化物を母体材料として情報提示物質を作製すると、非常に安定になり 、例えば 1000°Cの高温にされても破壊されず、対象物中に残存する。従って、対象 物が焼却処分されたり、さらには焼却後に不法投棄されても、情報提示物質の蛍光 を検出することができる。また、対象物が水性溶媒や有機溶媒の溶液あるいは濁色 液などの液体力もなる場合であっても、情報提示物質は化学変化を受けることがなく 、情報提示物質の蛍光を検出することができる。従って、たとえば、工場力 排出され る廃液等をも対象物として情報提示物質を付与することができる。  In particular, when an information presenting substance is prepared using an inorganic oxide as a base material, the information presenting substance becomes very stable, and is not destroyed even when heated to a high temperature of, for example, 1000 ° C., and remains in an object. Therefore, even if the object is incinerated or even illegally dumped after incineration, the fluorescence of the information presenting substance can be detected. In addition, even when the target object is a liquid solvent such as a solution of an aqueous solvent or an organic solvent or a turbid liquid, the information presenting substance is not subjected to a chemical change and the fluorescence of the information presenting substance can be detected. . Therefore, for example, an information presenting substance can be given to a waste liquid discharged from a factory as an object.
[0030] また、情報提示物質は、平均粒径が lnm— 20 μ m、好ましくは lOnm— 10 μ mの 微粒子がよぐその粒子は、二量体あるいは三量体などの多量体を形成してもよい。 情報提示物質の粒径を小さくすれば、作製履歴の違いによる情報提示物質の蛍光 の変化が生じやすくなるため、情報提示物質の種類を実質的に増加させて、真正な 情報提示物質の秘匿性を高めることができるという利点がある。このような微粒子を作 るには、化学反応法、ゾル ·ゲル法、コロイド法、気体凝固法、気体反応法、ガス中蒸 発法、スパッタリング法、ガラス結晶化法、沈殿法、スプレー法など様々な方法を利用 することができる。  [0030] Further, the information presenting substance is formed by a fine particle having an average particle diameter of lnm-20 μm, preferably lOnm-10 μm, which forms a multimer such as a dimer or a trimer. May be. If the particle size of the information presenting substance is reduced, the fluorescence of the information presenting substance is likely to change due to the difference in the production history.Therefore, the type of the information presenting substance is substantially increased, and the confidentiality of the authentic information presenting substance is increased. There is an advantage that can be increased. To produce such fine particles, chemical reaction method, sol-gel method, colloid method, gas coagulation method, gas reaction method, gas evaporation method, sputtering method, glass crystallization method, precipitation method, spray method, etc. Various methods can be used.
[0031] また、情報提示物質は、その表面が重水素、有機物などの表面修飾剤で修飾され たものや、母体材料以外の物質で周囲を被覆されたものとしてもよい。このようにする と、粒径や構造を固定ィ匕させることができ、かつ発光効率を向上させることができると ともに、特定の溶媒に解けやすくなり、周囲の物質とよりなじむことができる。 [0031] The information presenting substance may be a substance whose surface is modified with a surface modifying agent such as deuterium or an organic substance, or a substance whose periphery is covered with a substance other than the base material. Do this In addition, the particle size and the structure can be fixed, the luminous efficiency can be improved, and the compound can be easily dissolved in a specific solvent, and can be more compatible with surrounding substances.
[0032] このような情報提示物質を真贋判定される対象物に付与する方法は、対象物の表 面あるいは内部に情報提示物質を含ませることができる方法であれば、種々の方法 を採用することができ、たとえば、噴射、吹き付け、塗布、吸着、注入、充填、貼付、 浸透、混合、添加、あるいは化学結合 (重合、架橋、イオン結合等)を挙げることがで きる。  [0032] Various methods are used for applying such an information presenting substance to an object to be authenticated, as long as the information presenting substance can be included on the surface or inside of the object. Examples include spraying, spraying, applying, adsorbing, pouring, filling, sticking, penetrating, mixing, adding, or chemical bonding (polymerization, crosslinking, ionic bonding, etc.).

Specifically, it varies depending on the type of the object, etc., but when it is contained in the object, the range is preferably 0.1 ppm or more and 100 ppm or less relative to the object. When the concentration is 0.lppm or more, the fluorescence of the information presenting substance can be reliably detected. When the concentration is less than 100 ppm, the appearance and physical properties of many objects are not affected. Further, when the concentration is 0.5 ppm or more, it is possible to sufficiently secure the reliability of the measurement for detecting the fluorescence exhibited by the information presenting substance. When the content is 200 ppm or less, the appearance and physical properties of most objects are not affected, and the economic burden of providing an information presenting substance to the objects can be reduced.

Is detected.

And
[0043] 図 3は、この対象物蛍光スペクトル検出手段 21により、ある対象物 90から検出され た対象物蛍光スペクトルの波形の一例である。対象物 90には、 1種類または複数種 類の情報提示物質 91が付与されており、複数種類の場合、対象物 90から検出され る対象物蛍光スペクトルは、各情報提示物質 91が呈する蛍光スペクトル (個別蛍光 スペクトル）を重ね合わせたものとなって!/、る。  FIG. 3 is an example of a waveform of an object fluorescence spectrum detected from a certain object 90 by the object fluorescence spectrum detecting means 21. The object 90 is provided with one or more types of information presenting substances 91, and in the case of a plurality of types, the fluorescence spectrum of the object detected from the object 90 is the fluorescence spectrum exhibited by each information presenting substance 91. (Individual fluorescence spectra) are superimposed!
[0044] なお、この対象物蛍光スペクトル検出手段 21は、対象物 90から対象物蛍光スぺク トルを検出するのに先立って、対象物 90を検出位置に置かずに測定環境における 蛍光灯等による外乱光を予め検出することが好まし 、。こうして検出された外乱光の スペクトルは、対象物蛍光スペクトルの正確な照合に利用することができる。  Note that the object fluorescence spectrum detecting means 21 does not place the object 90 at the detection position before detecting the object fluorescence spectrum from the object 90 without using a fluorescent lamp or the like in the measurement environment. It is preferable to detect disturbance light due to in advance. The spectrum of the disturbance light thus detected can be used for accurate collation of the fluorescence spectrum of the object.
[0045] 対象物情報出力手段 22は、サーバ 30において行われた当該対象物 90の真贋判 定の結果と、当該対象物 90が真正品であった場合には、その対象物 90に関する情 報とを表示出力するものである。対象物情報出力手段 22は、たとえば液晶ディスプ レイカ 構成されている。  [0045] The object information output means 22 outputs the result of the authenticity determination of the object 90 performed in the server 30 and, if the object 90 is a genuine product, information on the object 90. Are displayed and output. The object information output means 22 is constituted by, for example, a liquid crystal display.
[0046] 送信手段 23は、サーバ 30に対し、前記対象物蛍光スペクトル検出手段 21によつ て検出した対象物蛍光スペクトルの情報を送信するものである。なお、送信する対象 物蛍光スペクトルの情報は、対象物蛍光スペクトル検出手段 21によって検出した情 報のすべてとしても、予め設定された一部分としてもよい。  The transmitting unit 23 transmits information on the target object fluorescence spectrum detected by the target object fluorescence spectrum detecting unit 21 to the server 30. The information on the fluorescence spectrum of the target object to be transmitted may be all of the information detected by the target fluorescence spectrum detecting means 21 or a part of the information set in advance.
[0047] この送信手段 23は、予め測定環境における外乱光のスペクトルが検出されている 場合には、対象物蛍光スペクトルの情報とともに、この外乱光のスペクトルに関する 情報もサーバ 30に送信することが好ましい。  When the spectrum of the disturbance light in the measurement environment is detected in advance, the transmission unit 23 preferably transmits information on the spectrum of the disturbance light to the server 30 together with the information on the fluorescence spectrum of the target object. .
[0048] 受信手段 24は、サーバ 30から、所定の応動動作指令を受信するものである。具体 的には、サーバ 30において行われた当該対象物 90の真贋判定の結果と、当該対象 物 90が真正品であった場合には、その対象物 90に関する情報とを前記対象物情報 出力手段 22に表示出力する指令等を受信する。  [0048] The receiving means 24 is for receiving a predetermined response operation command from the server 30. Specifically, the result of the authenticity determination of the target object 90 performed in the server 30 and, if the target object 90 is a genuine product, information on the target object 90, the target object information output means. An instruction to display and output to 22 is received.
[0049] <サーバ > サーバ 30は、検出装置端末 20によって検出された対象物蛍光スペクトルに基づ ヽ て、当該対象物の真贋を判定するものである。サーバ 30は、ハードウェア的には、 C PU、 RAM, ROM,ハードディスク装置等の記憶手段、情報通信装置、外部入出力 装置等を備えたコンピュータ力 構成されており、対象物の真贋を判定する処理等の 情報処理機能が、このコンピュータ上に構成されている。なお、サーバ 30は、複数台 のコンピュータに分散して構成してもよい。サーバ 30は、機能的に、個別蛍光スぺク トル記憶手段 31と、配合比率記憶手段 32と、スペクトル再現手段 33と、判定手段 34 と、対象物情報記憶手段 35と、対象物情報検索手段 36と、受信手段 37と、送信手 段 38とを備えている。 [0049] <server> The server 30 determines the authenticity of the target object based on the target object fluorescence spectrum detected by the detection device terminal 20. The server 30 is composed of a computer having hardware such as a storage unit such as a CPU, a RAM, a ROM, and a hard disk device, an information communication device, and an external input / output device, and determines authenticity of an object. Information processing functions such as processing are configured on this computer. Note that the server 30 may be configured to be distributed to a plurality of computers. The server 30 functionally includes an individual fluorescence spectrum storage unit 31, a mixture ratio storage unit 32, a spectrum reproduction unit 33, a determination unit 34, an object information storage unit 35, and an object information search unit. 36, receiving means 37, and transmitting means 38.
[0050] 個別蛍光スペクトル記憶手段 31は、予め選定された有限種類の真正な情報提示 物質について、特定の波長領域の電磁波の照射に対して、それぞれが放射する蛍 光スペクトルを個別蛍光スペクトルとして記憶しておくものである。  [0050] The individual fluorescence spectrum storage means 31 stores the fluorescence spectrum emitted from each of the finite kinds of genuine information presenting substances selected in advance in response to electromagnetic wave irradiation in a specific wavelength region as an individual fluorescence spectrum. It is something to keep.
[0051] 図 4は、この個別蛍光スペクトル記憶手段 31に記憶されている真正な情報提示物 質の個別蛍光スペクトルの例である。この例では、真正な情報提示物質として No. 1 一 No. 6の 6種類が予め選定されている。  FIG. 4 shows an example of the individual fluorescence spectrum of the genuine information presentation substance stored in the individual fluorescence spectrum storage means 31. In this example, six types of No. 1-No. 6 are selected in advance as authentic information presenting substances.
[0052] 個別蛍光スペクトル記憶手段 31は、各真正な情報提示物質につ!、て個別蛍光ス ベクトルを記憶していれば、真正な情報提示物質の名前や組成等、情報提示物質を 作成する手が力りとなる情報を合わせて記憶して 、なくてもょ 、。  [0052] The individual fluorescence spectrum storage means 31 creates an information presenting substance such as the name and composition of the genuine information presenting substance if an individual fluorescent vector is stored for each authentic information presenting substance. You don't even need to remember information that helps your hand.
[0053] 配合比率記憶手段 32は、有限種類の真正な情報提示物質を組み合わせる際の相 対的な配合比率のうち、有限種類の真正な配合比率を予め記憶するものである。  [0053] The blending ratio storage means 32 stores in advance the finite kinds of genuine blending ratios among the relative blending ratios when combining finite kinds of genuine information presenting substances.
[0054] 図 5は、この配合比率記憶手段 32に記憶されている真正な配合比率の例である。  FIG. 5 shows an example of a genuine compounding ratio stored in the compounding ratio storage unit 32.
この例では、真正な配合比率として No. 1— No. 5の 5種類が予め選定されている。 たとえば、 No. 1の配合比率は、 2種類の真正な情報提示物質を 1 : 3の比率で組み 合わせることを示している。  In this example, five types No. 1 to No. 5 are preliminarily selected as genuine compounding ratios. For example, the composition ratio of No. 1 indicates that two genuine information presenting substances are combined in a ratio of 1: 3.
[0055] スペクトル再現手段 33は、前記個別蛍光スペクトル記憶手段 31に予め記憶された 有限種類の真正な情報提示物質が放射する個別蛍光スペクトルを、前記配合比率 記憶手段 32に予め記憶された有限種類の真正な配合比率で組み合わせることによ り、対象物 90から検出した対象物蛍光スペクトルの再現を試みるものである。この再 現は、所定の波長範囲の全てで、対象物蛍光スペクトルと一致するような、個別蛍光 スペクトルの組み合わせを探索することによる。この所定の波長範囲は、個別蛍光ス ベクトルの特徴の一部または全部が現れる波長範囲を任意に適宜設定しておけばよ い。また、スペクトルが一致するとは、対比されるスペクトル間の差異力 ノイズ等の影 響を踏まえた所定の許容範囲内に収まって 、る場合等を含む。 [0055] The spectrum reproducing means 33 converts the individual fluorescence spectra emitted by the finite kinds of authentic information presenting substances stored in advance in the individual fluorescence spectrum storage means 31 into the finite types stored in the mixing ratio storage means 32 in advance. By combining them in a genuine compounding ratio, the attempt is made to reproduce the fluorescence spectrum of the object detected from the object 90. This re This is by searching for a combination of individual fluorescence spectra that matches the fluorescence spectrum of the object over the entire wavelength range. As the predetermined wavelength range, a wavelength range in which some or all of the characteristics of the individual fluorescence vectors appear may be set as appropriate. In addition, the case where the spectra coincide with each other includes a case where the spectra fall within a predetermined allowable range in consideration of the influence of noise, noise, and the like between the compared spectra.
[0056] この再現は、組み合わせるべき情報提示物質の種類と、組み合わせる際の配合比 率が予め有限種類しかなぐ情報提示物質の組み合わせ検討範囲を限定できるた め、計算負荷を小さくすることができる。  [0056] This reproduction can reduce the calculation load because the type of information presenting substances to be combined and the range of studying the information presenting substances in which the combination ratio when combining is limited to a finite type in advance can be limited. .
[0057] この再現は、有限種類の組み合わせを順に確認しても、任意の効率的な探索アル ゴリズムを採用してもよい。たとえば、検出された対象物蛍光スペクトルから、当該対 象物 90が真正品であれば確実に含まれるはずの情報提示物質を特定して探索範 囲をさらに限定したり、含まれる可能性の高い情報提示物質の組み合わせを優先的 に探索する手法等を採用することができる。  For this reproduction, a finite type of combinations may be confirmed in order, or any efficient search algorithm may be adopted. For example, based on the detected target fluorescence spectrum, if the target object 90 is a genuine product, an information presenting substance that is supposed to be surely included is specified to further limit the search range, or the search range is highly likely to be included. A method of preferentially searching for a combination of information presenting substances can be adopted.
[0058] スペクトル再現手段 33においては、対象物の測定環境における外乱光のスぺタト ルが予め検出されて 、る場合には、この外乱光のスペクトルも個別蛍光スペクトルと 同様に扱って、対象物蛍光スペクトルを再現するようにすることが好ましい。このよう にすると、測定環境における蛍光灯の種類等により外乱光の条件が変化するような 場合であっても、この変化に対応して、より適切かつ正確に対象物蛍光スペクトルの 再現を行うことができる。また、個別蛍光スペクトルを組み合わせるというスペクトル再 現手段 33が行う処理手順の中に外乱光の変化への対応を組み込むことができる。よ つて、別途の対応手段を要せず、簡素な構成を実現することができる。  [0058] In the spectrum reproducing means 33, the total light of the disturbance light in the measurement environment of the object is detected in advance, and if this is the case, the spectrum of the disturbance light is treated in the same manner as the individual fluorescence spectrum. It is preferable to reproduce the fluorescence spectrum of the substance. In this way, even if the conditions of disturbance light change due to the type of fluorescent lamp in the measurement environment, etc., it is possible to more appropriately and accurately reproduce the fluorescence spectrum of the target object in response to the change. Can be. In addition, it is possible to incorporate a response to a change in disturbance light into the processing procedure performed by the spectrum reproducing means 33 of combining individual fluorescence spectra. Therefore, a simple configuration can be realized without requiring a separate countermeasure.
[0059] 判定手段 34は、前記スペクトル再現手段 33によって、当該対象物 90から検出した 対象物蛍光スペクトルが再現できたカゝ否かから、当該対象物 90の真偽判定を行うも のである。対象物 90が真正品であれば、真正な情報提示物質が放射する個別蛍光 スペクトルの真正な配合比率で組み合わせて再現できるはずであり、再現できなけれ ば当該対象物 90は偽物と判定することができる。  The determination means 34 determines the authenticity of the target object 90 based on whether or not the fluorescence spectrum of the target object detected from the target object 90 can be reproduced by the spectrum reproducing means 33. If the object 90 is a genuine product, it should be able to be reproduced by combining the individual fluorescence spectra emitted by the genuine information presenting substance with a genuine compounding ratio. it can.
[0060] 仮に第三者によって真正品 90の対象物蛍光スペクトルが検出されたとしても、蛍光 を放射する物質 (情報提示物質）には無限に近い種類があるため、検出された対象 物蛍光スペクトルを構成している真正な情報提示物質を特定することは事実上不可 能である。したがって、仮に第三者によって真正品に近似した蛍光スペクトルを呈す る偽物が作製されても、それは真正な情報提示物質を組み合わせて作製されたもの であるとは事実上想定できない。そして、情報提示物質がそれぞれ呈する蛍光スぺク トルは所定の波長範囲を見れば異なるものであるから、偽の情報提示物質を組み合 わせて得られる偽物の蛍光スペクトルは、真正な情報提示物質を組み合わせて再現 した蛍光スペクトルと、所定の波長範囲のすべてで一致することはない。したがって、 偽造された対象物 90を識別することができ、真贋判断の高!ヽ信頼性を確保すること ができる。 [0060] Even if the fluorescence spectrum of a genuine object 90 is detected by a third party, there are almost infinite types of substances that emit fluorescence (information-presenting substances). It is virtually impossible to specify the genuine information presenting substance that constitutes the fluorescence spectrum of a substance. Therefore, even if a fake exhibiting a fluorescence spectrum similar to a genuine product is produced by a third party, it cannot be virtually assumed that the fake was produced by combining a genuine information presenting substance. Since the fluorescence spectrum exhibited by each of the information presenting substances differs when viewed in a predetermined wavelength range, the fluorescence spectrum of a fake obtained by combining a fake information presenting substance is obtained. Does not coincide with the fluorescence spectrum reproduced by combining in all of the predetermined wavelength range. Therefore, the forged object 90 can be identified, and high authenticity judgment and reliability can be ensured.
[0061] 対象物情報記憶手段 35は、対象物に関する情報を記憶するものである。  [0061] The target information storage means 35 stores information on the target.
[0062] 図 6は、この対象物情報記憶手段 35に記憶されている対象物に関する情報の例で ある。この対象物に関する情報は、有限種類の真正な情報提示物質のうち、 1または 複数の種類と、それらを組み合わせる際の相対的な配合比率に対応づけて記憶され ている。この例では、図 4に示す No. 1の情報提示物質と、同じく図 4に示す No. 3の 情報提示物質とが、図 5に示す No. 3の配合比率、すなわち 1 : 12の割合の組み合 わせに対して、 A社の商品名 B、ロット番号 XXという対象物に関する情報が対応づけ られている。 FIG. 6 shows an example of information on an object stored in the object information storage means 35. The information on the object is stored in association with one or more of the finite types of genuine information presenting substances and the relative mixing ratio when combining them. In this example, the No. 1 information presenting substance shown in Fig. 4 and the No. 3 information presenting substance also shown in Fig. 4 have the No. 3 compounding ratio shown in Fig. 5, that is, the 1:12 ratio. The combination is associated with information on the subject, which is the product name B and lot number XX of Company A.
[0063] 対象物情報検索手段 36は、前記判定手段 34によって対象物 90が真正品であると 判定された場合に、当該対象物 90に関する情報を特定するものである。前記判定手 段 34によって対象物 90が真正品であると判定された場合、前記スペクトル再現手段 33によって対象物蛍光スペクトルを再現するのに用いた真正な情報提示物質の種 類および配合比率は判明している。対象物情報検索手段 36は、この情報提示物質 の種類および配合比率に基づ!、て前記対象物情報記憶手段 35を検索し、当該対 象物 90に関する情報を抽出する。  The object information search means 36 specifies information on the object 90 when the judgment means 34 judges that the object 90 is genuine. When the object 90 is determined to be a genuine product by the determination means 34, the type and the mixing ratio of the genuine information presenting substance used to reproduce the fluorescence spectrum of the object by the spectrum reproducing means 33 are determined. are doing. The object information search means 36 searches the object information storage means 35 based on the type and the mixing ratio of the information presenting substance to extract information on the object 90.
[0064] 受信手段 37は、検出装置端末 20から、対象物蛍光スペクトル検出手段 21によつ て検出された対象物蛍光スペクトルの情報を受信するものである。  The receiving means 37 is for receiving, from the detecting device terminal 20, information on the target fluorescence spectrum detected by the target fluorescence spectrum detecting means 21.
[0065] 送信手段 38は、検出装置端末 20に対し、対象物 90に対する真贋判定に応じた所 定の応動動作指令を送信するものである。具体的には、サーバ 30において行われ た当該対象物 90の真贋判定の結果と、当該対象物 90が真正品であった場合には、 その対象物 90に関する情報とを表示出力する指令等を送信する。 [0065] The transmitting means 38 transmits to the detection device terminal 20 a predetermined response operation command according to the authenticity determination of the object 90. Specifically, it is performed in the server 30. An instruction or the like for displaying and outputting the result of the authenticity determination of the object 90 and, if the object 90 is genuine, information on the object 90 is transmitted.
[0066] このように、この真贋判定システム 10では、検出装置端末 20において、対象物 90 の真贋判定結果だけでなぐ対象物 90に関する情報も出力するため、より適正に対 象物 90を取り扱うことができる。 As described above, in the authenticity determination system 10, the detection device terminal 20 also outputs information about the target 90 that is not only the result of the authentication of the target 90, so that the target 90 can be handled more appropriately. Can be.
[0067] また、対象物 90の真贋判定に用いられる真正な情報提示物質の種類や蛍光スぺ タトル、さらにそれらの真正な配合比率を対象物 90のある現場から離れたサーバ 30 で一元的に管理するため、これにより真正な情報提示物質に関する情報の秘匿性を 高め、偽造のおそれを特に軽減することができる。 Further, the type of the authentic information presenting substance and the fluorescent statue used for the authenticity judgment of the object 90 and the genuine compounding ratio thereof are centrally managed by the server 30 remote from the site where the object 90 is located. For management purposes, this can increase the confidentiality of the information about the genuine information presenting substance, and can particularly reduce the risk of forgery.
[0068] また、対象物 90の真贋判定処理をサーバ 30側で行うため、検出装置端末 20に求 められる性能負担を軽減し、検出装置端末 21の小型化や可搬ィ匕を図ることができる In addition, since the server 30 performs the authenticity determination processing of the object 90, the performance load required for the detection device terminal 20 can be reduced, and the detection device terminal 21 can be downsized and portable. it can
[0069] <真贋判定処理の手順 > [0069] <Procedure of authenticity judgment processing>
次に、この真贋判定システム 10における真贋判定処理の手順について図 7のフロ 一チャートを参照しながら説明する。  Next, the procedure of the authenticity judgment processing in the authenticity judgment system 10 will be described with reference to the flowchart of FIG.
[0070] この真贋判定処理では、まず、検出装置装置端末 20にお 、て、所定の位置に置 かれた対象物 90に対して、対象物蛍光スペクトル検出手段 21によって対象物 90に 付与された情報提示物質 91が放射する対象物蛍光スぺ外ルが検出される (ステツ プ S10)。 [0070] In this authenticity determination process, first, in the detection device terminal 20, the object 90 placed at a predetermined position is given to the object 90 by the object fluorescence spectrum detecting means 21. An object fluorescent screen emitted by the information presenting substance 91 is detected (step S10).
[0071] こうして読み取られた対象物蛍光スペクトルの情報は、検出装置端末 20からサー ノ 30に送信される（ステップ S 12)。  [0071] The information on the target object fluorescence spectrum thus read is transmitted from the detection device terminal 20 to the laser 30 (step S12).
