Description

  The present invention relates to an image processing apparatus (image forming apparatus) such as a copying machine, a printer, and a multifunction machine, a control method thereof, and a program.

  Conventionally, there are copiers as devices for copying documents, etc., but with conventional copiers, copyrighted works, etc., documents containing information that would cause inconvenience if copied There was a problem that could be copied.

  In recent years, a technique that can restrict copying or make it possible to recognize that the image has been copied by printing a pattern image such as a copy-forgery-inhibited pattern or a barcode together with the image data has become popular. I am doing.

  For example, a technology that prints a pattern image such as a copy-forgery-inhibited pattern that has characters such as “copy prohibited” only on a copy, or a copy-forgery-inhibited pattern or barcode that stores data such as authentication information or job restriction types, together with image data. is there.

  Job restrictions include copy guards that prohibit copying, and copying that is permitted through authentication such as password entry.

  In this way, with increased security awareness, a document that you want to prohibit copying is printed on paper with a fine pattern such as a background pattern, so that when copying, the document can be identified as a copy-prohibited document, or copy The operation itself can be stopped.

  On the other hand, the development of “electronic paper” that combines the advantages of paper media and display media has been promoted, and it has become realistic to use it instead of paper. As an effect, it is expected that the environmental load can be reduced by suppressing paper consumption and conserving forests and suppressing CO2 emission by incineration.

  When electronic paper is used instead of paper as described above, a use case of copying with a copying machine is assumed, as with paper. However, the display resolution of electronic paper is much coarser than printing on paper, and fine patterns such as tint blocks cannot be displayed appropriately.

  For this reason, when electronic paper is copied by a copying machine, copying of a copy-prohibited document cannot be prevented, resulting in a leakage of confidential information.

  To solve such a problem, instead of displaying a fine pattern such as a tint block, it is possible to determine whether or not to perform a copying operation by acquiring copying permission information based on information stored in the storage unit of electronic paper One of the measures.

  As a solution, for example, Patent Document 1 proposes the following technique.

  That is, in Patent Document 1, copying permission / prohibition information is read from electronic paper, and the copying process is changed on the copying machine side based on the reading. If copying is prohibited, the display information is not read or the information is not read. Techniques for guiding to the path are shown.

JP 2005-012701 A

  However, in the above conventional technique, it is not possible to set security information for each page constituting a document stored in electronic paper. Depending on the document, there is a case where it is desired to partially apply security, and the prior art that determines all at once cannot meet this demand.

  Further, when copying a document displayed on electronic paper with a copying machine, if it is determined collectively, it is not possible to meet a demand for partial printing.

An object of the present invention is to provide an image processing apparatus capable of setting security information for each page of a document stored in electronic paper and determining whether copying is possible for each page , a control method therefor, and a program . There is.

In order to achieve the above object, an image processing apparatus according to claim 1 requests security information of a page displayed on the display medium in an image processing apparatus including a scanner and an interface for communicating with the display medium. Requesting means, acquiring means for acquiring the security information transmitted from the display medium in response to a request from the requesting means, and determining whether the scanner can scan based on the security information acquired by the acquiring means. Determination means, and when the plurality of pages displayed on the display medium are read , the request means requests a page break and requests security information of a newly displayed page, and the determination The means determines whether the scanner can scan based on security information of the newly displayed page. And wherein the Rukoto.

According to the image processing apparatus, the control method, and the program of the present invention, security information can be set for each page of a document stored in electronic paper, and whether or not copying can be performed for each page can be determined.
