Abstract

An image forming system includes a concealment word registration unit, an ID information acquisition unit, a concealment word managing unit, and an image forming unit. The concealment word registration unit registers a concealment word associating with a user. The ID information acquisition unit obtains creator ID information and execution person ID information from a print job, the creator ID information identifies a user as a creator of a document file, the execution person ID information identifies a user as an execution person of the image formation process. The concealment word managing unit uses the concealment words to determine a concealment region. The concealment words include the concealment word associated with the user identified by the creator ID information and the concealment word associated with the user identified by the execution person ID information. The image forming unit executes a masking process that makes the concealment region illegible.

First claim

What is claimed is:

1. An image forming system comprising:
a concealment word registration unit that registers a concealment word associating with a user, the concealment word being desired to be concealed in an image formation process;
an ID information acquisition unit that obtains creator ID information and execution person ID information from a print job, the creator ID information identifying a user as a creator of a document file, the document file being a target of the image formation process, the execution person ID information identifying a user as an execution person of the image formation process;
a concealment word managing unit that uses the concealment words to determine a concealment region based on an input from the user identified by the execution person ID information, the concealment words including the concealment word associated with the user identified by the creator ID information and the concealment word associated with the user identified by the execution person ID information, the concealment region being a region to be concealed in an image, the image being generated using the print job; and
an image forming unit that executes a masking process to form an image on which the masking process has been performed, the masking process making the concealment region illegible;
wherein the concealment word managing unit indicates a user interface screen to make the determination corresponding to an input on the user interface screen when the authority of the user identified by the creator ID information is inferior to the authority of the user identified by the execution person ID information, the user interface screen querying whether to determine the region that indicates the concealment word associated with the user identified by the creator ID information to be the concealment region.

2. The image forming system according to claim 1 ,
wherein the concealment word managing unit uses the concealment word associated with the user identified by the execution person ID information to determine the concealment region based on the input from the user identified by the execution person ID information when the creator ID information and the execution person ID information indicate an identical user.

3. The image forming system according to claim 1 ,
wherein the concealment word managing unit forcibly determines a region as the concealment region when authority of the user identified by the creator ID information is superior to an authority of the user identified by the execution person ID information, the region indicating the concealment word associated with the user identified by the creator ID information.

4. The image forming system according to claim 1 , further comprising
an image reading unit that reads an original image indicated on a document to generate original image data,
wherein the ID information acquisition unit obtains reader ID information that identifies a user as an execution person of reading the original image
the concealment word managing unit uses at least one of a predetermined code and a digital watermark to encrypt confidential information indicated on the concealment region and embed in the image, and the concealment word managing unit indicates a user interface screen that queries whether to restore the concealment word associated with the user having the authority inferior to authority of the user identified by the reader ID information among the embedded information, and the concealment word managing unit performs the restoration corresponding to an input on the user interface screen.

5. An image forming apparatus available for the image forming system according to claim 1 , comprising
a concealment word registration unit that registers the concealment word associating with a user, the concealment word being desired to be concealed in the image formation process.

6. An image forming method, comprising:
registering a concealment word associating with a user, the concealment word being desired to be concealed in an image formation process;
obtaining creator ID information and execution person ID information from a print job, the creator ID information identifying a user as a creator of a document file, the document file being a target of the image formation process, the execution person ID information identifying a user as an execution person of the image formation process;
using the concealment words to determine a concealment region based on an input from the user identified by the execution person ID information, the concealment words including the concealment word associated with the user identified by the creator ID information and the concealment word associated with the user identified by the execution person ID information, the concealment region being a region to be concealed in an image, the image being generated using the print job; and
executing a masking process to form an image on which the masking process has been performed, the masking process making the concealment region illegible;
wherein a user interface screen is indicated to make the determination corresponding to an input on the user interface screen when the authority of the user identified by the creator ID information is inferior to the authority of the user identified by the execution person ID information, the user interface screen querying whether to determine the region that indicates the concealment word associated with the user identified by the creator ID information to be the concealment region.

7. A non-transitory computer-readable recording medium storing an image formation program to control an image forming apparatus, the image formation program causing the image forming apparatus to function as:
a concealment word registration unit that registers a concealment word associating with a user, the concealment word being desired to be concealed in an image formation process;
an ID information acquisition unit that obtains creator ID information and execution person ID information from a print job, the creator ID information identifying a user as a creator of a document file, the document file being a target of the image formation process, the execution person ID information identifying a user as an execution person of the image formation process;
a concealment word managing unit that uses the concealment words to determine a concealment region based on an input from the user identified by the execution person ID information, the concealment words including the concealment word associated with the user identified by the creator ID information and the concealment word associated with the user identified by the execution person ID information, the concealment region being a region to be concealed in an image, the image being generated using the print job; and
an image forming unit that executes a masking process to form an image on which the masking process has been performed, the masking process making the concealment region illegible;
wherein the concealment word managing unit indicates a user interface screen to make the determination corresponding to an input on the user interface screen when the authority of the user identified by the creator ID information is inferior to the authority of the user identified by the execution person ID information, the user interface screen querying whether to determine the region that indicates the concealment word associated with the user identified by the creator ID information to be the concealment region.
