  By the way, in publications such as books, there are cases where there is a portion (a specific pattern for which copying is prohibited) that the publisher or the author wants to prohibit copying without permission. For example, a picture of a character that has registered a trademark, a logo mark, or the like. However, in the above-described prior art, no consideration has been given to restricting the printing of a copy-prohibited portion with respect to a book attached with an IC tag (RFID).

  The present invention has been made to solve such problems. The purpose of the present invention is to register a trademark by masking and printing (copying) a copy-prohibited portion when copying a publication such as a book. Another object of the present invention is to provide an image forming apparatus, an IC tag, an image forming method, and a program capable of preventing abuse of a character's picture or logo mark.

The present invention has been made to solve the above problems, and an image forming apparatus according to the present invention includes an IC tag reader / writer attached to a publication including a book, and a copy image of the publication.

Thereby, it is possible to prevent printing of a specific pattern (such as a mark) that is prohibited from being copied. For example, it is possible to prevent abuse of a picture or logo mark of a character registered as a trademark.
In addition, a specific pattern for prohibiting copying can be specified uniformly regardless of the type of publication. In addition, since a specific pattern for prohibiting copying can be directly read from the IC tag and used, pattern matching processing for detecting a copy-prohibited portion is facilitated.

An image forming apparatus according to the present invention includes an IC tag reader / writer attached to a publication including a book, and prints a copy image of the publication. A storage unit that stores image data of a specific pattern that is associated and prohibits copying, information on the presence or absence of a copy-prohibited portion of the publication recorded in advance on the IC tag, and a copy by the reader / writer Based on the copy prohibition information reading means for reading the identification information of the specific pattern to be prohibited and the information on the presence / absence of the copy prohibition portion read by the reader / writer, it is determined whether or not there is a copy prohibition portion in the publication.

  In the image forming apparatus and the image forming method of the present invention, the IC tag (RFID or the like) affixed to a publication has information on the presence / absence of a copy-prohibited portion of the publication and a copy-prohibited portion (specific pattern for prohibiting copying). ) Is stored, and the information stored in the IC tag is read by a reader / writer provided in the image forming apparatus. If there is a copy-prohibited part in the publication, the pattern is copied between the copy image and the specific pattern. Since the matching process is performed and the portion matching the specific pattern is masked and printed (copied), the specific pattern (mark or the like) prohibited from copying can be prevented from being printed. For example, it is possible to prevent abuse of a picture or logo mark of a character registered as a trademark.

  In the image forming apparatus of the present invention, the copy-prohibited part is designated by the publication page of the publication and the publication position in the page. The amount can be reduced, and the copy-inhibited portion detection process in the copy image can be easily performed.

  In the image forming apparatus of the present invention, the image data of a specific pattern that prohibits copying is stored in the IC tag, so that a specific pattern that prohibits copying regardless of the type of the publication can be obtained. Can be specified uniformly. In addition, since a specific pattern for prohibiting copying can be directly read from the IC tag and used, pattern matching processing for detecting a copy-prohibited portion is facilitated.

  Further, in the image forming apparatus of the present invention, information for identifying a specific pattern for which copying is prohibited is stored in the IC tag, so that it is possible to reduce the amount of information related to the copy-prohibited portion stored in the IC tag. At the same time, a specific pattern that prohibits copying can be specified uniformly regardless of the type of publication.

  In addition, the IC tag of the present invention is attached to a publication and records information on whether or not there is a copy-prohibited part in the publication and information on a specific pattern in which copying is prohibited. As a result, the image forming apparatus can be prevented from printing a specific pattern for which copying is prohibited. For example, it is possible to prevent abuse of a picture or logo mark of a character registered as a trademark.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a flowchart showing a processing procedure in an image forming apparatus according to the present invention. From reading of an IC tag (RFID or the like) 10 attached to a book 1 to be copied, scanning of a book page, and printing of a book page. It is the flowchart which showed the processing procedure until (copy).

Hereinafter, the flow of the process will be described with reference to FIG.
First, an IC tag (RFID or the like) 10 attached to a book 1 to be copied is read by a reader / writer 101. In the IC tag 10, “information on presence / absence of copy-prohibited portion” and “information regarding copy-prohibited portion (specific pattern for prohibiting copying)” for the book 1 are recorded. The data is read by the reader / writer 101 (step S1).

  Examples of the types of information related to the specific pattern for which copying is prohibited include, for example, “information on the page where the copy is prohibited and the place where the specific pattern is placed (the coordinates of the mask area)” and “the specific pattern for which copying is prohibited. “Image data (or data of a characteristic part of an image)”, “data for specifying (identifying) a specific pattern that prohibits copying”, and the like are stored.

  Next, the copy target page of the book 1 is read by the scanner 102a of the image forming apparatus (step S2).

  Next, in the image forming apparatus, it is determined based on the “copy prohibited portion presence / absence information” stored in the IC tag 10 whether or not the book 1 has a copy prohibited portion (a specific pattern for prohibiting copying) (step S3). ). If there is no copy-prohibited part, the process proceeds as it is (step S5).

  If it is determined in step S3 that there is a copy-prohibited portion, it is detected by pattern matching processing whether there is a copy that matches a specific pattern for which copying is prohibited (step S4). . In this pattern matching process, the processing method differs depending on the type of information specifying a specific pattern for which copying is prohibited.

  For example, the copy-prohibited location designation information is “information on the page of the copy-prohibited location and the specific pattern placement location (coordinates of the mask area)” or “image data (or image characteristics of the specific pattern that prohibits copying). The processing method differs depending on whether it is “partial data)” or “identification information of a specific pattern for which copying is prohibited”. This will be described in a configuration example of an image forming apparatus to be described later.

  When it is determined by the pattern matching process that there is no copy target page that matches the specific pattern, the process proceeds to the printing process (step S5). If there is a pattern that matches the specific pattern by the pattern matching process, the mask process is performed (step S6), and the mask process for the copy-prohibited portion is performed before the printing process is performed (step S5).
