れる。2. Description of the Related Art Conventionally, certificates such as time deposit certificates issued by banks require the deposit amount, interest rate, deposit date, maturity date, store number, customer number, account number, etc. The information printing unit is provided. Then, the certificate is issued only by the signature and the seal, and the authenticity is determined by collating the signature and the seal.

照合によって真偽の判定を行うのでは、偽造や不正発行

書の情報のチエックが自動読み取り器によって行われず
非能率的で有る。However, if the authenticity is determined by collating only the signature and the seal in this way, there is a problem that forgery or illegal issuance is likely to occur, and in these methods, the check of the document information is automatically read by the reader. It is not done by and is inefficient.

ーコードシステムを利用したいが、バーコードの存在は
知らしめたくない。Therefore, it is desired to use the bar code system. Although the conventional bar code is a high-speed and accurate information medium, it is ugly in design because the bar code is printed with black ink on the surface, and From the standpoint of preventing forgery, it must be said that it is inadequate. In other words, we want to use the bar code system, but we do not want to know the existence of the bar code.

りが不可能となるという問題がある。However, the amount of fluorescence generated in this case greatly changes depending on the background pattern of the paper on which the fluorescent substance is printed. This is because a difference in reflectance of the background pattern appears at the fluorescence wavelength and the excitation light wavelength. For this reason, there is a problem that the reading rate of mechanical reading is lowered or reading becomes impossible.

At this time, as each special fluorescent ink, an ink that is colorless in a visible light region such as white light of sunlight or a fluorescent lamp and changes into a color by irradiation with ultraviolet rays is used. Therefore, barcodes printed with these inks cannot be seen under normal light sources such as sunlight, and black light,
It can be identified by irradiating ultraviolet rays with a special light source such as a UV lamp.

I can't see the existence of the barcode because it is invisible. When this barcode is irradiated with light of a specific wavelength, the ink reacts and radiates visible light of a specific wavelength, and the visible light is detected by a highly sensitive image sensor to read the barcode information and forge it. It is possible to confirm whether or not it has been done and the customer.
