Description

明 細 書 識別機能を有する装置及びこれに使用する被識別部材 技術分野  Description Device having identification function and identified member used in the same Technical Field
本発明は、 識別機能を有する装置に関し、 特に、 プリンタ、 複写機、 ファク シミリ等で使用するィンクカートリッジ、 ゲーム機で使用する ROM力一トリ ッジ、 認証カード等の識別 （真贋、 即ち正規品か非正規品かの判定等） に関す る発明である。 背景技術  The present invention relates to an apparatus having an identification function, and in particular, identification of an ink cartridge used in a printer, a copier, a facsimile machine, a ROM force trig used in a game machine, an authentication card, etc. Etc.). Background art
例えば、 プリン夕、 複写機、 ファクシミリ等の印刷装置において、 非正規品 のインクカートリッジが使用されると、 印刷性能が劣化し、 故障を誘発し、 ま たメンテナンスに支障をきたす。 そこで、 インクカートリッジを識別して非正 規品の使用を排除する必要がある。  For example, when non-genuine ink cartridges are used in printers such as printers, copiers, and facsimile machines, the printing performance deteriorates, leading to malfunctions and hindering maintenance. Therefore, it is necessary to identify the ink cartridge and eliminate the use of irregular products.
こうした非正規品を識別する従来のシステムを図 17に示す。 図示において、 識別のための情報を記憶させた I Cチップ（I Cタグ）をカートリッジに設け、 カートリッジを装置本体に装着させたときに、 本体側に設けたリーダ （又はセ ンサ） が I Cチップ内の情報を読み取り、 その読み取られた情報に基づき、 真 贋判定ロジックが、 装着されたカートリッジの真贋を判定していた （例えば、 特開 2000— 246921、 特開 2004— 90517)。 発明の開示  Figure 17 shows a conventional system for identifying such non-genuine products. In the figure, an IC chip (IC tag) storing information for identification is provided on the cartridge, and when the cartridge is mounted on the main body of the apparatus, a reader (or sensor) provided on the main body side is provided in the IC chip. Based on the read information, the authenticity determination logic determines the authenticity of the mounted cartridge (for example, JP 2000-246921, JP 2004-90517). Disclosure of the invention
上述した従来のシステムにおいては、 使用される I Cチップに必要な情報が 記憶されているから、 I Cチップそのものを挿げ替えられてしまった場合は、 正規品か非正規品か区別がつかなくなつてしまうという致命的な問題がある。 そこで、 各種認証に利用される真性 〈真正〉 なランダムパルス発生器 （R P G) を、 こうしたカートリッジ等の識別に利用できないか検討してみると、 次 のような問題があることが分かつた。 In the conventional system described above, necessary information is stored in the IC chip used, so if the IC chip itself is replaced, it cannot be distinguished whether it is a genuine or non-genuine product. There is a fatal problem. Therefore, when examining whether an authentic random pulse generator (RPG) used for various types of authentication could be used to identify such cartridges, we found the following problems.
R P Gは、 通常、 基礎となる素子部分 （放射線源、 （例えば、 原子核の自然 崩壊により α粒子を放出する放射体） を含んだ溶液を、 例えば専用のプレート に滴下したコア部と、 放出された α粒子を受け止め電気信号に変化するセンサ 部とを一体に組み合わせたもの） とアンプなどの各種周辺回路を含む一個のモ ジュールとして取り扱われるように設計されている。 そのため、 R P Gは、 こ れと、 R P Gから不定期に出力されるパルスに応答するだけの単純な回路とを 組むだけで、 すぐに利用できるというメリットをもたらす。  RPGs are usually emitted by a core part that drops a solution containing the underlying element part (radiation source, for example, a radiator that emits alpha particles due to the natural decay of nuclei) onto a dedicated plate, for example. It is designed to be handled as a single module including various peripheral circuits such as amplifiers and a sensor unit that receives alpha particles and changes to an electrical signal. Therefore, RPG offers the advantage that it can be used immediately by simply combining it with a simple circuit that responds to pulses output irregularly from RPG.
しかし、 R P Gを使用せず、 他の回路に差し替えられたとき、 果たしてその パルスが自然原理に則した真性なものであるのか、 それとも人工的なものなの 力 瞬時に判断する術が無いため、 真贋判定が不可能となってしまう。 もちろ ん、 パルスをある一定の時間以上観察し続けられるようであれば、 パルスの間 隔に贋品固有の人工的な作為を見出すことは可能であるかも知れないが、 判定 時間に対して余裕が許されない場合（現状ではそのような場合がほとんど）は、 これでは解決にはならない。  However, when RPG is not used and it is replaced with another circuit, there is no way to instantly judge whether the pulse is genuine in accordance with the natural principle or artificial force. Judgment becomes impossible. Of course, if it is possible to continue observing the pulse for a certain period of time, it may be possible to find an artifact unique to the product at the interval of the pulse. If this is not allowed (mostly in the current situation), this will not solve the problem.
R P Gを利用するにせよ、 あるいは真贋を識別するための情報を記憶させた I Cチップを利用するにせよ、 これまでの真贋判定（正規品、非正規品の識別） の技術では、 判定する機器本体 （例えばプリン夕本体） と判定される部品 （ィ ンクカートリッジ等） 間を、 信号を交信する単純なインターフェイスを用いて 分断せざるを得ない。 信号源 （情報源） が I Cチップや R P Gモジュール等に 含まれそれ自体で完結して閉じている限り、 この部分で成りすませば、 イン夕 —フェイスの先にある認証機器本体を騙すことができてしまう。 しかもそれは 真贋を判定される側、 即ち、 インク力一トリッジ側を改造することで成立して しまう。 そのため、 個人でも改造が容易となり、 非正規品の使用に歯止めが効 かないことになる。 Whether the RPG is used or the IC chip that stores the information for identifying the authenticity is used, the conventional authentication technology (identification of genuine and non-genuine products) It is necessary to divide the parts (ink cartridges, etc.) that are judged to be (for example, the main body of the printer) using a simple interface that communicates signals. As long as the signal source (information source) is included in the IC chip, RPG module, etc. and is completely closed by itself, if it is made up of this part, the authentication device body at the end of the interface can be deceived. End up. Moreover, it can be realized by modifying the side where the authenticity is judged, that is, the ink force one side. This makes it easy for individuals to remodel, and is effective in using non-genuine products. It will not be.
こうした問題を解決するため、 信号源そのものを分断して、 その一部を認証 機器本体側に実装し、 本体側と部品側の両方が揃って初めて信号源として成り 立つようすることが考えられる。  In order to solve these problems, it is possible to divide the signal source itself and mount a part of it on the authentication device main body side so that it can be used as a signal source only when both the main body side and the component side are aligned.
しかし I Cチップそのものについては、 これを分割することは不可能であり、 I Cチップとその周辺回路の間で分割することになろうが、 それは単にイン夕 一フェイスを複雑にするだけであって、 問題を解決したことにはならない。 本願発明は、 こうした従来の問題点を解決して R P Gを真贋判定に利用する ことを一つの目的とするもので、 ランダムな電磁波又は粒子線を放出する放射 体を含むコア部を設けた被識別部材 （例えば、 インクカートリッジ、 ゲーム用 R OMカートリッジ、 認証カード等） と、 この被識別部材を取り外し可能に装 着する本体 （例えば、 プリン夕、 複写機、 ファクシミリ等、 P C、 ゲーム機、 カードリーダ等） とを有し、 前記本体には、 前記被識別部材が本体に装着され たときに被識別部材のコア部から放出される電磁波等を感知するセンサ部を 設けた識別機能を有する装置を提供する。  However, for the IC chip itself, it is impossible to divide this, and it will be divided between the IC chip and its peripheral circuits, but it only complicates the interface, It does not solve the problem.

図 1は、 本発明の一実施形態の梗概的な構成を示す図である。 ここでは、 図 1 7と比較のため、 I Cチップは、 I Cチップ Aと I Cチップ Bとに分割可能 なものとして説明している。  FIG. 1 is a diagram showing a schematic configuration of an embodiment of the present invention. Here, for comparison with FIG. 17, the I C chip is described as being divisible into I C chip A and I C chip B.
図示実施形態に係る装置は、 プリン夕、 複写機、 ファクシミリ等の印刷機能 を有する装置 1 0であって、 真贋 （正規品か非正規品か） の判定の対象となる 被識別部材は、 インク、 トナー等の消耗品を収納するカートリッジ又は容器等 The apparatus according to the illustrated embodiment is an apparatus 10 having a printing function, such as a printer, a copying machine, and a facsimile machine, and a member to be identified as an object of determination of authenticity (genuine or non-genuine) is ink. , Cartridges or containers for storing consumables such as toner
1である。 このカートリッジ等 1は、 装置の本体 2に取り外し自在に装着でき る。 1. This cartridge 1 can be detachably attached to the main body 2 of the apparatus.
図 1において、 I Cチップは、 真性なランダムパルスの発生器 （R P Gモジ ユール） を含む。 この R P Gモジュール中の要となる R P G素子は、 自然崩壊 によりランダムな放射線 （特に α粒子線） を放出する放射体を有するコア部 1 Α (後述の図 2参照)と、 その放射線を受け止め、 電気信号に変換するセンサ (例 えばフォトダイオード)部 2 A (後述の図 2参照）とがー対となつて構成される。 図示の如く、 本実施形態では、 I Cチップは、 被識別体 （カートリッジ等） 側 の I Cチップ Aと装置の本体側の I Cチップ Bとに分けられる。 I Cチップ A は、 ？0素子のコァ部1八を含み、 カートリッジ等 1に取り付けられ、 I C チップ Bはセンサ部 2 Aを含み、 装置の本体 2に取り付けられる。 R P Gモジ ユールにおいて、 R P G素子を除く部分は、 センサから得た信号を増幅整形す るアンプ回路等 （図示せず） で、 図示実施形態では I Cチップ Bに含まれる。 本発明では、 従来の真贋判定と異なり、 信号線を境に分断するのではなく、 構成素子そのものを分断するため、 コピー I Cチップによる成りすましや、 リ セットによる判定の突破などが不可能となる。 In Figure 1, the IC chip includes an intrinsic random pulse generator (RPG module). The key RPG element in this RPG module is the core part 1 有 す る (see Fig. 2 below) that has a radiator that emits random radiation (especially α-particle radiation) due to natural decay, and receives the radiation. A sensor (for example, a photodiode) part 2 A (see FIG. 2 described later) for converting the signal into a signal is configured as a pair. As shown in the figure, in this embodiment, the IC chip is divided into an IC chip A on the identification object (cartridge or the like) side and an IC chip B on the main body side of the apparatus. IC chip A is? It includes a core part 18 of 0 elements and is attached to a cartridge 1 and the like, and the IC chip B includes a sensor part 2 A and is attached to the main body 2 of the apparatus. In the RPG module, the part excluding the RPG element is an amplifier circuit (not shown) for amplifying and shaping the signal obtained from the sensor, and is included in the IC chip B in the illustrated embodiment. In the present invention, unlike the conventional authenticity determination, the constituent elements themselves are not divided at the signal line, but the copy IC chip impersonation or It will not be possible to break through the set.
なお、 本実施形態では、 R P G素子のコア部 1 Aの放射体として α粒子線を 放出するものを用いたが、 他にベータ線、 ガンマ線等を放出するものの利用も 考えられる。 更に、 半導体の熱雑音を利用したもの、 擬似的なランダムパルス 発生器の信号源等も適用可能である。  In the present embodiment, an emitter that emits an α particle beam is used as the radiator of the core portion 1 A of the RPG element. However, it is also possible to use an emitter that emits a beta ray, a gamma ray, or the like. In addition, semiconductor thermal noise sources, pseudo random pulse generator signal sources, etc. can be applied.
図示において、 R P G素子のコア部 1 Αを取り付けたカートリッジまたは容 器等 1を装置の本体 2に装着されると、 力一トリッジ等側のコア部 1 Aと本体 側のセンサ部 2 Aとが一体になつて R P G素子（R P Gモジュール）を構成し、 本体側のセンサ部 2 Aが、 カートリッジ等側のコァ部 1 Aの放射体からの放射 線を受けとり、 I Cチップ Bから装置の本体側に設けた真贋判定ロジック 2 B に検知信号 （電気信号） を出力し、 本体に装着されたカートリッジ等が正規品 In the figure, when a cartridge or container 1 attached with a core 1 of the RPG element is attached to the main body 2 of the apparatus, the core 1 A on the force bridge side and the sensor 2 A on the main body side are connected. An RPG element (RPG module) is formed as a unit, and the sensor unit 2A on the main unit side receives radiation from the radiator of the core unit 1A on the cartridge side, and the IC chip B is connected to the main unit side of the device. A detection signal (electrical signal) is output to the installed authenticity determination logic 2 B, and the cartridge mounted on the body is a genuine product.
(本物） であると判定される。 Determined to be (genuine).
本実施形態では、 カートリッジ等を装置本体に装着する前にセンサ部が作動 することがないように、 カートリッジ等の装着前には閉じられ、 また装着した とき又はその後に開くシャッター 〈図示せず〉 を設ける。 このシャッターは、 カートリッジ等側及び本体側のいずれか一方又は両方に設けられ、 α粒子を遮 蔽するために金属製となっている。 またこのシャツ夕一は、 R P G素子のコア 部とセンサ部とを保護する機能も合せ持つ。  In this embodiment, a shutter that is closed before mounting the cartridge or the like and opened when the cartridge is mounted or after that is mounted so that the sensor unit does not operate before the cartridge or the like is mounted on the apparatus main body (not shown). Is provided. This shutter is provided on one or both of the cartridge side and the main body side, and is made of metal to shield the α particles. The shirt also has the function of protecting the core and sensor of the RPG element.
なお、 被識別部材に設けるシャツ夕一は被識別部材のコア部を覆う剥離自在 のテープ又は剥離紙等を利用可能である。  The shirt provided on the member to be identified can use a peelable tape or a release paper that covers the core of the member to be identified.
図 2は、 図 1に示した実施形態の要部である R P G素子を示す。 カートリツ ジ等 1を装置の本体 2に装着する前は、 R P G素子は、 力一卜リッジ等 1に取 り付けたコア部 1 Αと本体 2に取り付けたセンサ部 2 Aとが互いに分離され、 カートリツジ等 1を本体 2に装着すると、 コア部 1 Aとセンサ部 2 Aとが一体 化して R P G素子として機能する。 なお、 コア部は、 例えば、 放射線源 （例え ば (¾粒子を放出する放射体） を含む溶液を滴下装置で所要箇所に滴下する等し て形成される。 FIG. 2 shows an RPG element which is a main part of the embodiment shown in FIG. Before the cartridge 1 or the like is mounted on the main body 2 of the device, the RPG element has the core 1 attached to the force ridge 1 etc. and the sensor 2 A attached to the main body 2 separated from each other. When the cartridge 1 or the like is attached to the main body 2, the core 1A and the sensor 2A are integrated to function as an RPG element. For example, the core portion may be prepared by, for example, dropping a solution containing a radiation source (for example, a radiator that emits ¾ particles) to a required location with a dropping device. Formed.
本発明に係るプリン夕等の印刷機能を有する装置において、 力一トリッジ等 In an apparatus having a printing function such as printing according to the present invention,
1に搭載された R P G素子のコア部 1 Aは、 何ら電気的エネルギーの供給も無 い状態で放射線 （α粒子線） を放出し続けている。 カートリッジ等 1が装置の 本体 2に装着されると、 カートリッジ等側のコア部 1 Αと本体側のセンサ （フ オトダイオード） 部 2 Aとが一体となって R P G素子 （R P Gモジュール） を 構成する。 そしてシャツ夕一が開けられると、 コア部 1 Aからの放射線をセン サ部 2 Aが感知する。 このときは、 センサ部 2 Aに対し、 受信信号 （パルス） として認識できるような何らかの刺激を与えるのはコア部 1 A以外にはない から、 装着されたカートリッジ等 1は、 そのようなコア部を有する正規品 （本 物） であると判定される。 The core 1A of the RPG element mounted on 1 continues to emit radiation (α particle beam) without any electrical energy supply. When cartridge etc. 1 is installed in the main body 2 of the device, the core part 1 の on the cartridge etc. side and the sensor (photodiode) part 2 A on the main body together form an RPG element (RPG module). . When the shirt evening is opened, the sensor part 2A detects the radiation from the core part 1A. At this time, since there is no other stimulus than the core part 1 A to give any stimulus that can be recognized as a received signal (pulse) to the sensor part 2 A, the mounted cartridge 1 etc. It is determined that the product is genuine (genuine).
本願発明に係るカートリッジ等に取り付けられる R P G素子のコア部は、 そ の占有面積は小さく、 プリンタのインク力一トリッジのような形状の小さな製 品にも容易に取り付け可能であり、 また、 自発的に放射線を継続的に放出する から、 電源の供給の必要がな.く、 それだけ安価でもある。  The core of the RPG element attached to the cartridge or the like according to the present invention has a small occupation area, and can be easily attached to a product having a small shape such as a printer's ink strength. Because it emits radiation continuously, it is not necessary to supply power and it is also inexpensive.
なお、 悪意のある人間が、 センサ部をバイパスしてコア部から放出される放 射線を直接受け取ることで、 R P G素子 （R P Gモジュール） 全体の 「成りす まし」 を図ろうとしても、 本発明に係る R P G素子は、 そのセンサ部が装置の 本体側に実装されているから、 そのような 「成りすまし」 は、 センサ部の実装 されている本体部位の周辺に手を加えることになり、 装置本体の改造となる。 これは、 「不法な改造」 となり、 装置のメーカ一は補償の対象から除外するこ とになるだろう。  Even if a malicious person attempts to “spoof” the entire RPG element (RPG module) by directly receiving the radiation emitted from the core section, bypassing the sensor section, the present invention Since the sensor part of such an RPG element is mounted on the main body side of the device, such “spoofing” means that the peripheral part of the main body part where the sensor unit is mounted is changed. It becomes a remodeling. This would be an “illegal modification” and the equipment manufacturer would be excluded from compensation.
図 3は、 本発明の別の実施形態を示す。 この実施形態では、 R P G素子のコ ァ部から受け取るパルスの特性を利用してパルスを監視する機能を盛り込ん だものでる。 図 1及び図 2の実施態様と比較し、 この実施形態が異なるのは、 コア部から受け取るパルスを判定するセクションを設けたことである。 かかる 判定セクションを設けることにより、 より確実な真贋判定が可能となる。 FIG. 3 shows another embodiment of the present invention. In this embodiment, a function for monitoring a pulse using the characteristics of the pulse received from the core part of the RPG element is incorporated. Compared with the embodiment of FIGS. 1 and 2, this embodiment is different in that a section for determining a pulse received from the core section is provided. Take By providing a judgment section, more reliable authentication can be made.
R P G素子のセンサ （フォトダイオード） 部は光を信号に変えるデバイスで あるので、 悪意のある人間が、 この素子に光を当てることで擬似的にパルスを 生み出し、 R P G素子のコア部を他のデバイスで代用しようと図る可能性があ る。 しかし、 R P G素子から放射される真性なランダムなパルスは、 その特性 として、 パルスの発生する確率が指数分布上に展開されるから、 そのような分 布状態を調べることで、 発生じているパルスが R P G素子からのものか、 人為 的なものなのか判断することができる。 図示の R P Gパルス監視機構 （手段、 回路） 2 2は、 そうした機能を有する判定手段である。 具体的には、 この機構 は、 インクカートリッジを交換してからプリンタ本体が印刷準備を完了するま での数秒の時間を利用して、 コア部からのパルスをサンプリングし、 その発生 確率が指数分布に展開されるかどうかを調べ、 真性なランダムパルスか否かを 判定する。 なお、 2 1はインクカートリッジの受け側 （センサ部を含む） を示 し、 2 3はプリン夕のヘッド機構、 2 4はプリンタの印刷機構を示す。  Since the sensor (photodiode) part of the RPG element is a device that converts light into a signal, a malicious person creates a pseudo-pulse by applying light to this element, and the core part of the RPG element is used as another device. There is a possibility of trying to substitute. However, since the intrinsic random pulse emitted from the RPG element has the characteristic that the probability of the pulse being generated is developed on an exponential distribution, the generated pulse can be determined by examining such a distribution state. It is possible to determine whether is from an RPG element or artificial. The RPG pulse monitoring mechanism (means, circuit) 2 2 shown in the figure is a judging means having such a function. Specifically, this mechanism samples the pulses from the core using the time from the replacement of the ink cartridge until the printer body is ready for printing, and the probability of occurrence is exponentially distributed. To see if it is a true random pulse. 21 indicates the ink cartridge receiving side (including the sensor), 23 indicates the print head mechanism, and 24 indicates the printer print mechanism.
こうした本発明のパルス監視機構までも真似て製作しょうとすると、 カート リッジ側にマイコンチップや電源が必要となるため、 そのような贋品の製作は 手間とコストがかかり割が合わないものとなるであろう。  If you try to imitate even the pulse monitoring mechanism of the present invention, a microcomputer chip and a power supply are required on the cartridge side, so manufacturing such a product is laborious and costly. I will.
図 4は、 本発明の更に別の実施形態を示す。 図示の装置では、 コア部 1 O A を設けた真贋判定の対象物 (被識別部材） 1 0 (例えばィンク力一トリッジ）を、 真贋判定する本体機器 1 1の収納部 1 2に装着し、 センサ部 1 2 A (例えばフ オトダイオードを含む） でコア部からのランダムパルスを検知する。 乱数生成 部 1 3は、 センサ部 1 2 Aによって検知されたパルスの発生間隔を計測し乱数 に変換する。 頻度計数部 1 4は乱数生成部 1 3によって生成された乱数の発生 頻度 （発生確率、 登場頻度） をカウントする。 判定部 1 5は、 頻度計数部 1 4 でカウントする際に、 後述する評価範囲等の設定を行い、 発生頻度をグラフ化 するとともに真贋判定を行う。 なお、 この実施形態では、 判定結果は P C 1 6 のモニタ一上に表示する。 FIG. 4 shows yet another embodiment of the present invention. In the apparatus shown in the figure, an object (identified member) 10 0 (for example, an ink force trough) for authenticity determination provided with a core 1 OA is attached to the storage unit 1 2 of the main body device 1 1 for authenticity determination, and the sensor Random pulses from the core section are detected by section 1 2 A (including photodiodes, for example). The random number generator 1 3 measures the pulse generation interval detected by the sensor 1 2 A and converts it into a random number. The frequency counting unit 14 counts the occurrence frequency (occurrence probability, appearance frequency) of the random number generated by the random number generation unit 1 3. When counting by the frequency counting unit 14, the determination unit 15 sets an evaluation range to be described later, graphs the occurrence frequency, and performs authenticity determination. In this embodiment, the determination result is PC 1 6 Is displayed on the monitor.
ランダムパルス発生器によって発生されるパルスは、 例えば図 5に示すよう に、 パルスの発生間隔 （r 1乃至 r 8 ) が不定であるため、 あるパルスの発生 した瞬間からその次のパルスの発生までの経過時間はランダム （ランダムパル スの発生） となる。 しかしながら、 このようなランダムパルスの発生確率は、 図 6に示すように、 ある瞬間 （tO) から見て、 より短い間隔で発生する確率は 高く、 経過時間が長くなるにつれ （tn)、 その発生確率は 0 %へ限りなく近づ いていく傾向がある。 即ち、 経過時間をそのまま乱数とした場合、 その値は指 数分布に沿った偏りが存在する。 図 4に示す装置による真贋判定は、 ランダム パルスの発生確率がこのような指数分布を呈する性質を利用する。  For example, as shown in Fig. 5, the pulse generated by the random pulse generator has an indefinite pulse generation interval (r 1 to r 8), so the period from the moment when one pulse is generated to the next pulse is generated. The elapsed time is random (occurrence of random pulses). However, as shown in Fig. 6, the probability of occurrence of such a random pulse is higher at a shorter interval as seen from a certain moment (tO), and as the elapsed time becomes longer (tn) Probability tends to approach as much as 0%. In other words, if the elapsed time is directly used as a random number, there is a bias in the value distribution along the index distribution. The authenticity determination by the device shown in Fig. 4 utilizes the property that the probability of random pulse generation exhibits such an exponential distribution.
図 7は、 判定部 1 5でグラフ化される乱数の発生頻度を表示するモニターの 画面を示す。 図中の標本曲線は理想の指数分布を示している。 ランダムパルス を監視し続ければ、 やがて標本結果のほとんどはこの曲線上に収束する。  Figure 7 shows a monitor screen that displays the frequency of random numbers generated by the decision unit 15. The sample curve in the figure shows the ideal exponential distribution. If the random pulse is continuously monitored, most of the sample results will eventually converge on this curve.
真贋判定には、 ある程度の数量のパルスをサンプリングする必要があるため、 時間がかかる。 そこで、 真贋判定の時間を減らすとともにより確実な判断を行 うために、 以下に示す近似範囲、 評価範囲の設定を行う。 なお、 これらの範囲 の設定は、 判定対象ごとに調整が必要となろう。  Since it is necessary to sample a certain number of pulses, it takes time to determine the authenticity. Therefore, the following approximate range and evaluation range are set in order to reduce the time for authenticity determination and make more reliable determination. These range settings will need to be adjusted for each target.
近似範囲： パルスの発生頻度がこの範囲に収まれば有効と判断できるよう な、 理想の標本曲線に近似する上限及び下限にはさまれた領域をいう。  Approximate range: An area between the upper and lower limits approximating an ideal sample curve that can be judged to be effective if the frequency of pulse generation falls within this range.
評価範囲： 発生するパルスの時間間隔の有効な判定領域をいう。 即ち、 時 間間隔の短い部分と長い部分とをカットして実効的な判定領域を定める。  Evaluation range: This is the effective judgment area for the time interval of generated pulses. In other words, an effective judgment area is defined by cutting a short time portion and a long time portion.
なお、 本実施形態では、 こうして設定された評価範囲内において、 真贋判断 の基準となる合格率 （％) を設定することができ、 また、 真贋判定のための制 限時間も設定できる。  In the present embodiment, within the evaluation range thus set, a pass rate (%) as a reference for authenticity determination can be set, and a time limit for authenticity determination can also be set.
図 8は、 本実施形態における真贋判定の手順を示すフローチャートである。 まずバッファ等の初期化を行う （ステップ S 1 )。 これは、 真贋判定対象（例 えば、 インクカートリッジ） を本体に装着する際に入り込んだ光によってパル スが発生し、 それによつて生成された乱数がバッファに残っている可能性があ るからで、 例えば、 乱数生成部のパルス監視回路内で乱数をバッファリングす る構成の場合は、 この開始段階でバッファに残っている値を破棄する。 FIG. 8 is a flowchart showing the procedure of authenticity determination in the present embodiment. First, the buffer is initialized (step S1). This is the authentication target (example For example, there is a possibility that a pulse is generated by the light that enters when the ink cartridge is installed in the main body, and the generated random number may remain in the buffer. For example, the pulse of the random number generator If the random number is buffered in the monitoring circuit, the value remaining in the buffer is discarded at this start stage.
次に、乱数生成部 1 3で、パルス間隔をタイマーで計測して乱数値を得る（ス テツプ S 2 )。 このとき、 パルスの発生の有無が調べられ （ステップ S 3 )、 パ ルスが検出できない場合、 判定対象の装着状態を確認する旨の表示を行い （ス テツプ S 4 )、 ステップ 2に戻す。 ただし、 ステップ 2の乱数の取得の開始か ら一定の時間以上パルスが検出できない場合は、 贋品と判断する。  Next, the random number generation unit 13 measures the pulse interval with a timer to obtain a random value (step S 2). At this time, the presence / absence of a pulse is checked (step S 3). If a pulse cannot be detected, a display to confirm the mounting state of the judgment target is displayed (step S 4), and the process returns to step 2. However, if a pulse cannot be detected for a certain time after the start of random number acquisition in Step 2, it is determined to be a good product.
次に乱数の発生頻度 （登場頻度） をカウントし （ステップ S 5 )、 発生頻度 をグラフ化する （ステップ S 6 )。 グラフ化は、 乱数の発生頻度の内、 その瞬 間に最も多い頻度を 100%として、 その他の頻度はその割合を計算することに より行う。 仮に 0から 255までの乱数の内、 128が 5回で最も多いとすると、 グラフではその 128を示す位置に 100%の棒グラフを描画し、同じ時に 129の 登場頻度が 4回であった場合、 4 ÷ 5 =0.80であるので、 129の位置に 80% の棒グラフを描画する。 また、 グラフ化に際しては、 前述した近似範囲、 評価 範囲を考慮する。  Next, the frequency of occurrence of random numbers (appearance frequency) is counted (step S5), and the frequency of occurrence is graphed (step S6). Graphing is performed by calculating the ratio of the occurrence frequency of random numbers, with the most frequent frequency being 100%, and other frequencies. If the random number from 0 to 255 is 128, the highest number is 128. If the graph draws a 100% bar graph at the position showing 128, and 129 appears 4 times at the same time, Since 4 ÷ 5 = 0.80, draw 80% bar graph at 129 position. In graphing, the approximate range and evaluation range described above are considered.
そして、 制限時間内に合格比率を満たした場合、 真品と判断し、 制限時間内 に合格比率を満たせなかった場合、贋品と判断する（ステップ S 7乃至 S 1 0 )。 また、 まだ合格しておらず、 かつ経過時間もまだ制限時間内であれば、 再びス テツプ S 2に戻る。  If the pass ratio is satisfied within the time limit, it is determined to be genuine, and if the pass ratio cannot be satisfied within the time limit, it is determined to be a good product (steps S7 to S10). If it has not passed yet and the elapsed time is still within the time limit, the process returns to step S2.
本発明の実施形態には、 他に、 （a ) ランダムな電磁波又は粒子線を放出す る放射体を含むコア部を設けた被識別部材、 及び （b ) ランダムな電磁波又は 粒子線を放出する放射体を含むコア部を設けた、 被識別部材に取り付ける識別 用部材がある。  The embodiment of the present invention includes, in addition, (a) a member to be identified provided with a core portion including a radiator that emits random electromagnetic waves or particle beams, and (b) emits random electromagnetic waves or particle beams. There is a discriminating member that is attached to the discriminating member, provided with a core including a radiator.
前記 （a ) の部材としては、 前述した識別機能を有する装置に使用される、 「インク、 トナー等を収納するカートリッジ又は容器等」、 また、 「データ、 プ ログラム等を記録した又は記録するための媒体、 又は当該媒体を含むボード、 カートリッジ等」 がある。 即ち、 本発明は、 ランダムな電磁波又は粒子線を放 出する放射体を含むコア部を設けたインク、 トナー等を収納するカートリッジ 又は容器等、 更に、 ランダムな電磁波又は粒子線を放出する放射体を含むコア 部を設けたデータ、 プログラム等を記録した又は記録するための媒体、 又は当 該媒体を含むボード、 カートリッジ等を提供する。 As the member (a), used for the device having the identification function described above, There are “cartridges or containers for storing ink, toner, etc.” and “mediums for recording or recording data, programs, etc., or boards, cartridges, etc. containing such media”. That is, the present invention relates to an ink, a cartridge, or a container that stores a core portion including a radiator that emits random electromagnetic waves or particle beams, and a radiator that emits random electromagnetic waves or particle beams. A medium for recording or recording data, a program, or the like provided with a core section including a board, a cartridge, or the like including the medium is provided.
前記 （2 ) の部材、 即ち、 ランダムな電磁波又は粒子線を放出する放射体を 含むコア部を設けた、 被識別部材に取り付ける識別用部材としては、 例えば、 ランダムな電磁波又は粒子線を放出する放射体を含むコア部と、 このコア部を 覆う剥離自在のテープ （剥離紙、 シール等を含む） とを有するシール （主とし て認証用） がある。 以下、 図 9乃至 1 2を参照して、 このシールについて詳説 する。  As the member for identification (2), that is, the identification member attached to the identification target member provided with the core portion including the radiator that emits the random electromagnetic wave or particle beam, for example, the random electromagnetic wave or particle beam is emitted. There is a seal (mainly for authentication) having a core part including a radiator and a releasable tape (including release paper and a seal) covering the core part. Hereinafter, this seal will be described in detail with reference to FIGS.
なお、 本発明は、 放射線源を含むコア部を、 直接設けるか、 あるいは識別用 部材 （識別用シール） を介して設けることができれば 被識別部材 （真贋判定 対象） を上記に限定する必要はない。 従って、 例えば、 携帯機器その他に使用 されるバッテリも本発明の識別対象とすることができる。  In the present invention, it is not necessary to limit the identification target member (authentication determination target) to the above as long as the core portion including the radiation source can be provided directly or via an identification member (identification seal). . Therefore, for example, a battery used for a portable device or the like can also be an identification target of the present invention.
図 9は、 認証用シールの構造を示す断面図である。 図の右側には、 部分的に 拡大した図が描かれている。 図示の如く、 このシール 3 0は、 多層構造で、 最 上面から、 被識別部材 （ここではインクカートリッジ） を使用する際に剥がす テープ （剥離紙等も含む） 3 1、 剥離性のある接着剤 3 2、 コア部 1 Aを設け たプレート部材 3 3、 剥離性の無い接着剤 3 4、 被識別部材を破棄するときに 剥がすテープ （剥離紙等を含む） 3 5及び剥離性のある接着剤 3 6を含む。 コ ァ部 1 Aは、 プレート部材 2 2の適所に設けた凹陥部に、 例えば、 放射線源を 含む速乾性溶液を滴下することによって形成する。 なお、 図示のシールの構造 は例示であって、 限定的なものではない。 例えば、 テープ 3 5及び接着剤 3 6 は不要な場合もあるであろう。 FIG. 9 is a cross-sectional view showing the structure of the authentication seal. On the right side of the figure is a partially enlarged view. As shown in the figure, this seal 30 has a multilayer structure, and is peeled off from the uppermost surface when a member to be identified (here, an ink cartridge) is used. Tape (including release paper, etc.) 3 1, A peelable adhesive 3 2, Plate member with core 1 A 3 3, Non-peelable adhesive 3 4, Tape to be removed when the identified member is discarded (including release paper) 3 5 and peelable adhesive Including 3-6. The core portion 1A is formed by, for example, dropping a quick-drying solution containing a radiation source into a recessed portion provided at an appropriate position of the plate member 22. It should be noted that the structure of the illustrated seal is an example and is not limited. For example, tape 3 5 and adhesive 3 6 May not be necessary.
図 1 0及び図 1 1は、実際に真贋判定対象の製品（インクカートリツジ）に、 本実施形態の認証シールを適用した例を示す。  FIG. 10 and FIG. 11 show an example in which the authentication sticker of the present embodiment is applied to a product (ink cartridge) that is actually subject to authenticity determination.
図示実施形態では、 プリンタ用インクカートリッジの製造工程で、 充填口 1 Bからインクを充填し終えた時点で、 その口を塞ぐように、 本願のシールを貼 り付ける （図 1 0参照）。 次に、 カートリッジをプリン夕に装着する直前にテ —プ 3 1を剥がし、当該カートリッジをプリン夕本体に装着する（図 1 1参照）。 コア部 1 Aは剥き出しとなり、 ひ粒子の放出が始まるため、 プリンタ側に搭載 されたセンサ （フォトダイオード） 部で真贋判定の認証が可能となる。  In the illustrated embodiment, in the manufacturing process of the ink cartridge for a printer, when the ink is completely filled from the filling port 1 B, the seal of the present application is applied so as to close the port (see FIG. 10). Next, remove the tape 31 just before installing the cartridge in the printer, and install the cartridge in the printer main body (see Fig. 11). Since the core part 1A is exposed and the emission of particles begins, authentication of the authenticity judgment can be performed by the sensor (photodiode) part mounted on the printer side.
本実施形態では、 放射線源を含む溶液を専用のプレートに滴下し、 その上を α粒子の放出を防ぐためのテープで覆い、 出来上がったシールを被識別部材 (インクカートリッジ） に貼るという作業だけであるから、 識別対象の製造ェ 程内で行う必要はなく、 別個専用のラインで行えばよく、 カートリッジの製造 工程を複雑化させることはない。  In this embodiment, a solution containing a radiation source is dropped on a dedicated plate, covered with a tape to prevent the release of alpha particles, and the completed seal is applied to a member to be identified (ink cartridge). Therefore, it does not have to be performed within the manufacturing process to be identified, it can be performed on a separate dedicated line, and does not complicate the cartridge manufacturing process.
なお、 カートリッジ内のインクが切れてインクの再充填をしょうとしたとき、 テープ 3 5を剥がしてインクの充填口を開けなければならない （図 1 2参照）。 このとき、 コア部 1 Αはテープ 3 5とともに剥がされてしまい、 そのため、 セ ンサ部は、 R P G素子からのパルスを受信できなくなる。 従って、 本発明の認 証シールを利用すれば、 プリン夕に装着されたカートリッジが、 正規品か、 又 はインクをカートリッジ内に再充填した再生品かどうか識別できる。 即ち、 不 正なカートリッジの使用を排除することができる。  When ink in the cartridge runs out and you try to refill the ink, you must remove the tape 35 and open the ink filling port (see Figure 12). At this time, the core 1 Α is peeled off together with the tape 35, so that the sensor cannot receive the pulse from the RPG element. Therefore, by using the authentication sticker of the present invention, it is possible to identify whether the cartridge mounted in the printer is a genuine product or a regenerated product in which ink is refilled in the cartridge. That is, the use of an incorrect cartridge can be eliminated.
本実施形態の認証シールは、厚さは数ミリ程度の薄いもので、 ICチップによ る認証と異なり、 電気的な機構が必要無いため、 一見しただけでは、 ただ単に 充填口を塞ぐためのシールにしか見えない。 コア部 1 Aを覆ったテープ 3 1を 剥がすのも、 使用開始までインクが出ないように空気穴を塞いでいたのを開放 する機構も兼ねているとすれば、 利用者も疑いは持たないであろう。 即ち、 予 めこのシールが認証シールであるということを知らなければ、 真贋判定機構そ のものが搭載されていることさえ気づかれない。 The authentication seal of this embodiment is a few millimeters thick, and unlike the authentication by IC chip, there is no need for an electrical mechanism, so at first glance, it is just for plugging the filling port. I can only see the seal. If the tape 3 1 covering the core 1 A is peeled off and the air hole is closed so that ink does not come out until the start of use, the user will have no doubt. Will. That is Therefore, if you do not know that this seal is an authentication seal, you will not even realize that the authentication mechanism itself is installed.
なお、 本実施形態の認証シールは、 真贋判定対象の製品とは別の生産工程で 量産できるため、 真贋判定が必要となる一部のロットにのみ適用するなどとい つた柔軟な対応も可能である。  In addition, since the authentication sticker of this embodiment can be mass-produced in a production process that is different from the product subject to authenticity determination, it is possible to respond flexibly by applying it only to some lots that require authenticity determination. .
C D , D V D等のメディアの識別に本実施形態の認証シールを使用すること ができる。 この場合は、 例えば、 センサ （フォトダイオード） 部を備えた専用 ドライブ （C DZD V D · R OMドライブ） に、 認証シールの貼られたメディ ァを挿入することで真贋判定を行い、 コピーされたメディアでは読み込まない といった実施形態となる。 、  The authentication sticker of this embodiment can be used for identifying media such as CD and DV. In this case, for example, authenticate the media by inserting the media with the authentication sticker into a dedicated drive (C DZD VD · ROM drive) equipped with a sensor (photodiode), and copy the media. In such an embodiment, it is not read. ,
社員証などの個人証明書の識別に本実施形態の認証シールをしょうするこ とができる。 例えば、 各種証明のカードなどに本実施形態の認証シールを貼つ ておけば、 偽造カードの判定が可能となる。  The authentication sticker of this embodiment can be used to identify personal certificates such as employee ID cards. For example, if the authentication sticker of this embodiment is pasted on various certification cards, it becomes possible to determine a forged card.
携帯ゲーム機の R OM力一トリ.ッジ等に本実施形態の認証シールを使用す ることができる。 例えば、 提供されるソフトがカートリッジ式のゲーム機の場 合、 そのカートリッジに本実施形態の認証シールを貼ることで海賊版の判定が 可能となる。  The authentication sticker of this embodiment can be used for a ROM game of a portable game machine. For example, if the software provided is a cartridge-type game machine, it is possible to determine a pirated version by attaching the authentication sticker of this embodiment to the cartridge.
次に認証シール （剥離可能なテープ） に放射線源を塗布する別の方法につい て説明する。  Next, another method for applying a radiation source to the authentication seal (peelable tape) is described.
放射線源を含んだ溶液を滴下する方法は、 当該シールの生産数量が多いと溶 液の滴下に多大の時間を要す （例えば、 剥離可能なテープシートが横 5 0枚 X 縦 5 0枚 （2 5 0 0枚） の場合 2 5 0 0回滴下を行うことが必要である）。 時間当たりの生産数量を上げるために、 プリン夕 （例えばインクジェットプ リン夕） を利用する方法が考えられる。 もっとも、 この方法は、 プリン夕のへ ッドを横に移動し、 指定した場所に放射線源を含む溶剤を印字し、 シートを口 —ルアップし、 再度ヘッドを横に移動して印字するので、 印字のための時間を 必要とする。 そこで、 もっとも効率的な方法として別の印刷技術を使う方法が ある。 この方法は、 例えば、 （1 ) 放射線源を溶かした透明の溶剤を印刷され た文字 （例えばブランド名）、 図形等の上に再度印刷する、 （2 ) 印刷インクに 放射線源を溶解させ印刷する。 前者の印刷例を図 1 3に示す。 即ち、 「P r o d u e t」 の " P " の部分 （一点鎖線で囲まれた斜線部、 実際は透明） に放射 線源を含んだ溶剤を印刷する。 なお、 文字の大きさにより、 印刷する箇所は、 1文字以上の文字数になる場合もある。 The method of dripping a solution containing a radiation source requires a great deal of time for dripping the solution if the number of seals produced is large (for example, the strippable tape sheet is 50 horizontal x 50 vertical ( In the case of 2 5 0 0 sheets), it is necessary to drop 2 5 0 0 times). In order to increase the production volume per hour, a method that uses printing (for example, inkjet printing) can be considered. However, this method moves the head of the printer sideways, prints the solvent containing the radiation source at the specified location, pulls up the sheet, moves the head sideways again, and prints. Time for printing I need. Therefore, the most efficient method is to use another printing technology. This method is, for example, (1) Printing again on printed characters (for example, brand names), graphics, etc. with a transparent solvent in which the radiation source is dissolved, (2) Printing by dissolving the radiation source in printing ink . An example of the former print is shown in Figure 13. That is, the solvent containing the radiation source is printed on the “P” part of “P roduet” (the shaded area surrounded by the one-dot chain line, actually transparent). Depending on the size of the characters, the printed part may have more than one character.
次に、 放射線源を含むコア部 （例えばインクカートリッジに貼った認証用シ ール （剥離可能なテープ） に放射線源を含む溶液を滴下しまたは放射線源を含 む溶剤を印刷して形成したコア部） とセンサ部 （例えばインクカートリッジを 格納するケースに設けたセンサ部） との間に隙間があると光が漏れて入り安定 的な真贋判定ができないので、 これを改善する方法を述べる。 真贋判定対象物 Next, a core part formed by dropping a solution containing the radiation source onto a core part containing the radiation source (for example, an authentication seal (peelable tape) affixed to an ink cartridge) or printing a solvent containing the radiation source. If there is a gap between the sensor part and the sensor part (for example, the sensor part provided in the case for storing the ink cartridge), light will leak out and stable authentication cannot be determined. Authentication object
(例えばインクカートリッジ） では、 図 1 4 Bに示すように、 認証用シール 4 0を、 適度なクッションが生じるよう、 クッション材 4 0 Aを設けた 2重構造 にする。また、図 1 4 Aに示すように、真贋判定対象物を装着する本体 6 0 (例 えばィンクカートリッジを格納するケース） のセンサ部が設けられた部位に、 筒状の突起物 6 1を設け、 真贋判定物異物 （インクカートリッジ） を本体 （ケ ース） に格納したときに、 隙間 （遊び） が生じないようにして、 識別用シール 4 0に設けたコア部 5 0からのパルスを本体 （ケース） に設けたセンサ部が確 実に検知できるようにする。 この筒状の突起物 （外壁部） の材質は、 真贋判定 物異物 （インクカートリッジ） がずれて隙間が生じることのないように、 格納 ケース本体よりも少し柔らかい材質にするのが望ましい。 (For example, an ink cartridge) As shown in FIG. 14B, the authentication sticker 40 has a double structure provided with a cushioning member 40A so that an appropriate cushion is generated. Also, as shown in FIG. 14A, a cylindrical projection 61 is attached to a portion of the main body 60 (for example, a case for storing an ink cartridge) to which an object for authenticity determination is attached. Provide a pulse from the core part 50 provided on the identification seal 40 so that no gap (play) occurs when the authenticity object (ink cartridge) is stored in the main body (case). Ensure that the sensor provided on the body (case) can be detected reliably. The cylindrical projection (outer wall) should be made of a material that is slightly softer than the housing case so that there is no gap due to misalignment of the foreign object (ink cartridge).
本発明は、 更に、 被識別部材が、 デ一夕、 プログラム等を記録した又は記録 するための媒体、 又は当該媒体を含むボード、 カートリッジ （R OM力一トリ ッジ） 等であり、 前記本体が当該媒体等を利用する P C、 ゲーム機、 力一ドリ ーダ、 あるいは C DZD V D— R OMドライブ等の装置の本体である場合にお いても実施可能である。 なお、 こうした ROMカートリッジのように、 真贋対 象となる製品が充分に小さいもので、 なおかつそれ単体には電源を搭載しない ものであれば、 本発明のような RPG (ランダムパルス発生器） を利用した真 贋判定はより強固なものとなるであろう。 In the present invention, the member to be identified is a medium for recording or recording a program or the like, or a board including the medium, a cartridge (ROM force one), etc. Is the main body of a device such as a PC, game machine, power driver, or CDZD VD—ROM drive that uses the media. However, it can be implemented. If such a ROM cartridge is a sufficiently small product that does not have a power supply, use an RPG (random pulse generator) like the present invention. The authentication will be more robust.
図 15、 本発明に係る真贋判定用のセンサ部をフォト I C (フォトディテク ト I Cを含む） に組み込んだ実施形態を示す。 図示のものは、 特に、 CDZD VD用の光ピックアップに使用されるフォト I Cに本発明の真贋判定用のセ ンサ部を設けたものである。  FIG. 15 shows an embodiment in which a sensor unit for authenticity determination according to the present invention is incorporated in a photo IC (including a photo detector IC). In the illustrated example, the sensor unit for authenticity determination according to the present invention is provided on a photo IC used for an optical pickup for CDZD VD.
光ピックアップ (後述の図 16参照)には、 半導体レーザ一 （図示では 2波長 LD) と受光素子がキーデバイスとして用いられる。 図 15において、 符号 a 乃至 d (DVD用）、 A乃至 D (CD用） 及び E， Fは、 受光素子を示し、 こ れらの素子から得られる信号に基づき、 トラッキング信号、 フォーカス信号が 生成される。 これらの受光素子は、 通常プラスチック又はガラス製のカバーが 施されるが、 真贋判定用のセンサにはカバーは不要であろう。 なお、 光ピック アップは、 CDZDVDメディアのドライブユニットに実装されるから、 セン サ部を設け、 判定対象である CD/DVDメディアを装着するための本体は、 このドライブュニットとなる。  In an optical pickup (see Fig. 16 below), a semiconductor laser (two-wavelength LD in the figure) and a light receiving element are used as key devices. In FIG. 15, symbols a to d (for DVD), A to D (for CD), and E and F indicate light receiving elements, and a tracking signal and a focus signal are generated based on signals obtained from these elements. Is done. These light receiving elements are usually covered with a plastic or glass cover, but a cover for an authenticity sensor would not be necessary. Since the optical pickup is mounted on the drive unit of the CDZDVD media, the sensor unit is provided and the main body for mounting the CD / DVD media to be judged is this drive unit.
一方、 真贋判定の対象となる CDZDVDメディアには、 放射線源を含むコ ァ部を設ける。 コア部は、 当該 CDZDVDメディアをドライブユニットに挿 入した状態で真贋判定用のセンサ部に対向する当該 CDZDVDメディア上 の位置に、 放射線源を溶解した溶液をプリント等して形成される。 図 16は、 ドライブュニッ卜に CDZDVDメディアを挿入した状態での、 CDZDVD メディアとセンサ部を設けたフォト I Cとの位置完成を示す。 図示では、 ドラ イブュニッ卜に CDZDVDメディアを挿入した初期状態で真贋判定をし、 真 性であると判定されると、 当該 CDZDVDメディアを更に移動し、 ドライブ ュニット内に装着するように構成されているが、 ドライブュニット内にし装着 した状態で真贋判定するように構成してもよい。 本実施形態によれば、 コア部 を設けた真性なメディアと、 コア部を有しない不正なメディア （コピーされた もの） とを判別することができる。 On the other hand, a CDZDVD media subject to authentication is provided with a core section that includes a radiation source. The core part is formed by printing a solution in which the radiation source is dissolved at a position on the CDZDVD medium facing the sensor unit for authenticity determination with the CDZDVD medium inserted in the drive unit. Figure 16 shows the completed position of the CDZDVD media and the photo IC with the sensor section with the CDZDVD media inserted in the drive unit. In the figure, it is configured so that the authenticity is determined in the initial state in which the CDZDVD medium is inserted into the drive unit, and if it is determined to be authentic, the CDZDVD medium is further moved and mounted in the drive unit. Installed in the drive unit You may comprise so that authenticity may be determined in the state which carried out. According to the present embodiment, it is possible to discriminate an authentic medium provided with a core part and an unauthorized medium (a copied one) that does not have a core part.
なお、 こうしたコア部を、 その表面に印刷する等して形成可能なものとして、In addition, such a core part can be formed by printing on its surface,
CD/DVDメディアの他にゲーム用メディア、 ディプリ用メディア等が考え られる。 この出願は 2007年 6月 1日に出願された日本国特許出願番号第 200 7 - 14691 1号及び 2007年 8月 31日に出願された日本国特許出願 番号第 2007-226895号の優先権を主張するものであり、 その内容を 引用してこの出願の一部とするものである。 In addition to CD / DVD media, game media, diprising media, etc. can be considered.
