A printed matter identifying device that identifies a printed matter printed by a predetermined printing apparatus and having on its surface at least two or more areas that are different in surface property to each other includes: an image reading unit that controls an external light source and camera so that reflected images displayed by the light source respectively on the areas of the surface of the printed matter are captured by the camera to acquire respective image information of the reflected images; an image processing unit that performs image-processing of the image information of the reflected images acquired by the image reading unit; and an image determination unit that uses a differential value between the image information of the reflected images obtained by the image-processing by the image processing unit, to determine whether or not the printed matter is a printed matter printed by the predetermined printing apparatus.
A printed matter identifying device that identifies a printed matter printed by a predetermined printing apparatus and having on its surface at least two or more areas that are different in surface property from each other, said printed matter identifying device comprising:

This invention relates to authenticity determination of a printed matter, and in particular, to a printed matter identifying device and a printed matter identifying system for identifying whether or not a printed matter is that printed out from a predetermined printing apparatus.
Conventionally, as a method for preventing a printed matter from being copied illegally by copy machines, there is a way of printing in the printed matter a pattern having a high resolution more than that by the resolving powers of the copy machines. However, in recent years, capabilities of the copy machines have been enhanced dramatically, so that the resolving powers of the copy machines are increased, and thus, by such a way, it becomes difficult to prevent a printed matter from being copied illegally.
In this respect, for example in Patent Document 1, as a method for making it unable by the copy machines to reproduce a feature of the printed matter, there is disclosed a way in which a print paper formed with a concavity-convexity forming layer that causes volume increase by heat treatment, is used so that concavities and convexities are developed on a printed image, and a copied matter is identified depending on whether the concavities and convexities with a predetermined pattern emerge or not. Further, for example in Patent Document 2, there is disclosed a method in which a hologram is provided on a printed matter and authenticity determination of the printed matter is made depending on whether or not there is a match between identification information and that from the hologram.
FIG. 1 includes a block diagram showing an internal configuration of a printed matter identifying device and a diagram illustrating a configuration for identifying a printed matter, according to Embodiment 1 of the invention.
FIG. 2 is a configuration diagram showing a configuration of a thermal-transfer printer that is a printing apparatus for printing a printed matter given as an object to be identified by the printed matter identifying device according to Embodiment 1 of the invention.
FIG. 3 is a block diagram showing a system configuration of the thermal-transfer printer given as a printing apparatus.
Hereinafter, for illustrating the invention in more detail, embodiments for carrying out the invention will be described according to the accompanying drawings.
