| titleOfInvention | Method and copying machine for preventing illegal copying |
| abstract | A copying machine characterized in that said machine comprises illegal copying preventive image pattern storage means for storing previously an illegal copying preventive image pattern which has been previously formed on a subject with at least one IR absorption material absorbing IR, an IR transmission filter for transmitting only the IR region, image information input means for inputting an IR image information from the reflected light of a subject to be copied, and copying acceptance judgement means for comparing the IR image information received from the image information input means with the illegal copying preventive image pattern having been stored, and if both are coincident, performing illegal copying preventive processing, while if otherwise, performing copying processing; and an illegal copying preventive method. An information carrying sheet of securities, identification cards and the like which is used for the above-mentioned copying machine and method, and provided with an illegal copying preventive image pattern in which the existence of the above-mentioned image pattern is hardly discriminated by the naked eye. An illegal copying preventive image pattern which prevents an unnecessary exposure by combining a plurality of patterns having an absorption in different regions used in the sheet and incorporating a dummy pattern, and which is difficult to perform falsifying/altering/counterfeiting action; and an ink composition which is used for the image pattern, and has a high IR absorption. n According to the present invention, whether copying is acceptable or not can be promptly judged with a less memory capacity to shorten copying processing time, and falsifying/altering/counterfeiting action can be securely prevented in such a manner that the application of an illegal copying preventive processing is not noticed easily by a third party. |
