Confidential information provision device, image forming apparatus and system
A confidential information provision device includes: an information acquisition unit configured to acquire a confidential level of information that is to be printed on a recording medium; and a provision unit configured to provide confidential information to the recording medium in accordance with the confidential level, the confidential information provided to the recording medium being constituted of a material that is detectable in a non-contact manner.
1. A confidential information provision device comprising:
at least one hardware processor configured to acquire an image that is printed on a recording medium and acquire a confidential level of information of the image based on at least one of a keyword, a sentence, or a figure included in the image; and
a provider configured to provide confidential information to the recording medium in accordance with the confidential level of information, the confidential information provided to the recording medium being constituted of a material that is detectable in a non-contact manner.
2. The confidential information provision device according to claim 1 , wherein
the material constituting the confidential information provided to the recording medium is a material that absorbs or reflects at least a part of radio waves.
3. The confidential information provision device according to claim 1 , wherein
the material constituting the confidential information provided to the recording medium is a volatile material.
4. The confidential information provision device according to claim 3 , wherein
the volatile material is odorless to a human.
5. The confidential information provision device according to claim 3 , wherein
the volatile material is an organic compound having a hydroxyl group or an organic compound having a hydroxyl group and an ether group.
6. The confidential information provision device according to claim 4 , wherein
the volatile material is an organic compound having a hydroxyl group or an organic compound having a hydroxyl group and an ether group.
7. The confidential information provision device according to claim 1 , wherein
the material constituting the confidential information provided to the recording medium is an invisible material.
8. An image forming apparatus comprising:
the confidential information provision device according to claim 1 ; and
an image forming unit configured to form an image other than the confidential information on the recording medium.
9. The image forming apparatus according to claim 8 , further comprising
an accommodation unit configured to accommodate a plurality of types of the recording medium, and
a selection unit configured to select a type of the recording medium according to the confidential level.
10. The image forming apparatus according to claim 9 , wherein,
in a case where the confidential level is not higher than a predetermined level, the confidential information is provided to the recording medium by the provision unit, and
in a case where the confidential level is higher than the predetermined level, the image forming unit forms an image on a recording medium including a magnetic body.
11. A system comprising: the image forming apparatus according to claim 8 ; and
a detector configured to detect the confidential information provided to the recording medium.
12. The system according to claim 11 , wherein
the detector is provided at a gate through which a person goes in and comes out.
13. The system according to claim 12 , further comprising
an alert generation device at the gate, the alert generation device configured to generate an alert in response to the confidential information being detected by the detector.
14. The system according to claim 12 , further comprising
an air stream generation device configured to generate an air stream toward the detector via the confidential information passing through inside of the gate in a case where the material constituting the confidential information provided to the recording medium is a volatile material.
15. The system according to claim 14 , further comprising
a person detection sensor at the gate, wherein
the air stream generation device is caused to operate in response to entry of a person into the gate being detected by the person detection sensor.
16. The system according to claim 14 , further comprising
