Embodiment Construction

[0024] Composition of Exemplary Embodiments

[0025] FIG. 1 shows the composition of an information management system 100 according to an exemplary embodiment of the present invention. The information management system 100 is, for example, a system constructed in an environment of outputting (creating) documents such as an office. As shown in FIG. 1 , an information management system 100 is provided with a plurality of printers 10 , a plurality of access control devices 20 , a network 30 and an administrator terminal 40 .

[0026] Furthermore, the environment in which the information management system 100 is built includes a plurality of areas with different security levels. In this exemplary embodiment, it is assumed that there are "area A" with a relatively high security level and "area B" with a relatively low security level. Documents with a relatively high level of importance are output in the area A, while documents with a relatively low level of importance are output ...

Abstract

A detection system includes: an acquiring unit that acquires document data representative of a document which includes a plurality of pages; a selector that selects, for each page of the document, a first printing sheet which contains a detected element or a second printing sheet which does not contain the detected element such that the first printing sheet is selected for at least one page; a supplier that supplies the first or the second printing sheet selected by the selector; a printer that sequentially prints the document acquired by the acquiring unit on the printing sheets supplied by the supplier; a detector that detects a detected element contained in a printing sheet on which the document is printed by the printer; and a reporter that reports detection of the detected element ina printing sheet by the detector.

Description

technical field [0001] The present invention relates to techniques for ensuring the security of printed documents. Background technique [0002] Confidential documents should be protected so that they cannot be copied and taken out of controlled areas without permission. For example, as a technique for preventing unauthorized take-out of printed documents, a technique described in JP2005-84184A is known. An image forming apparatus is disclosed in JP 2005-84184A in which special paper containing a specific material such as metal is used. [0003] However, this special paper is quite expensive. Therefore, users are forced to bear high costs, or are forced to give up using this special paper. In the case where individual documents are printed by a single printing apparatus and their importance or confidentiality levels differ, it is difficult to effectively protect printed materials according to the protection of different importance or confidentiality levels using this conv...
