  Next, the cutting process and the recording process executed by the shredder 1 according to the present invention will be described with reference to the flowchart of FIG.

  Prior to the description of the cutting process and the recording process, creation of a document will be described. First, the user creates a document (data) using the word processor software of the PC 20 or the like. Then, through the input I / F 202 of the PC 20, document identification information, for example, a user name (document creator name), a document manager name (for example, a document creator boss), a document expiration date, etc. Enter information. The identification information setting unit 212 of the PC 20 converts the input identification information into, for example, a QR code or the like, and arranges it in the upper right corner and lower left corner (see FIG. 2) of the document data. A user prints document data including identification information using an image forming apparatus. This printed material is referred to as a document 30 in FIG.

  When a user, a third party, or the like places the document 30 on the shredder 10 (step S1), the scanner 102 of the shredder 10 scans the document 30, generates image data of the document 30, and records it in the data recording unit 111. (Step S2). The discarding unit 103 cuts the document 30 (step S3).

  Next, the identification information extraction unit 114a of the data management unit 114 extracts the identification information from the image data of the document 30 recorded in the data recording unit 111 (step S4). Then, the identification information analysis unit 114b analyzes the identification information extracted by the identification information extraction unit 114a, and obtains various information related to the document 30 such as a creator name, an administrator name, and an expiration date of the document 30 (Step S5). ). At this time, for example, as shown in the management table 40 shown in FIG. 5, the name of the image data and the information of the image data are recorded in the data recording unit 111 together with the image data of the document 30. Note that the contact information of the creator of the document 30 and the administrator, for example, an e-mail address is preferably recorded. The e-mail address is recorded in the identification information together with the creator name and the administrator name, for example.

  Then, the data management unit 114 notifies the creator and manager of the document 30 that the document 30 has been cut and the image data of the document 30 has been recorded in the shredder 10 (step S6). As the notification method, for example, the data transmission unit 112 may create an email including the content of the notification and send it to an email address such as the creator of the document 30. At this time, it is preferable to include the image data recording destination information of the document 30 in the body of the mail. The recording destination information includes a URL and a file path.

Thereafter, the creator who has received the mail can access the image data of the document 30 recorded in the shredder 10 via the PC 20. In this case, the data access unit 211 of the PC 20 transmits an access request command including the creator's name (ID) to the shredder 10.
The data management unit 114 of the shredder 10 that has received the access request command permits access to the image data of the document 30 corresponding to the creator.

  Various methods can be used as the access method. For example, if the shredder 10 has a WEB server function, the image data of the document 30 can be accessed (browser display) from the PC 20 via the browser, or the image data can be downloaded from the shredder 10. Further, the shredder 10 may send an email with image data attached to the email address of the creator. In addition, the image data of the document 30 may be printed by the image forming apparatus.

  In this way, the creator of the document can know that the document has been discarded. In addition, it is possible to restore an accidentally discarded document with a simple operation.

Note that access to the image data of the document 30 may be restricted according to the security level. For example, the security level of the document 30 is included in the identification information 31 of the document 30, and the data management unit 114 of the shredder 10 records this security level in the management table 40 shown in FIG.
Then, the data management unit 114 performs access restrictions according to the security level, for example, access restrictions such as browser display impossibility, download impossibility, e-mail / fax transmission impossible, and printing impossibility.

By restricting access in this way, information leakage can be effectively prevented.
In step S2, when the image data of the document 30 is recorded in the data recording unit 111, if the expiration date has already passed, it may be deleted immediately.

Next, the image data deletion process of the document 30 recorded in step S2 of FIG. 4 will be described using the flowchart of FIG.
Here, it is assumed that the image data of the document 30 is already recorded in the data recording unit 111 of the shredder 10.
The data management unit 114 of the shredder 10 periodically refers to the management table 40 shown in FIG. 5 and detects whether image data whose expiration date has passed is recorded in the data recording unit 111 (step S11).

When image data whose expiration date has passed is recorded in the data recording unit 111 (step S12 / YES), the data management unit 114 determines whether the image data may be automatically deleted or a document corresponding to the image data. Confirmation with 30 creators (step S13). Note that not only the creator but also the administrator may be confirmed.
That is, before deleting the image data of the document 30, the creator of the document corresponding to the image data is notified via e-mail or the like to delete the image data.

  Various methods can be used for this confirmation processing (notification). For example, the data transmission unit 112 transmits an e-mail in which the deletion confirmation URL is described in the e-mail body to the e-mail address of the creator of the document 30. Then, if the creator who receives this e-mail accesses the deletion confirmation URL, it is assumed that the creator has approved the deletion. Further, if the creator of the document 30 receiving the electronic mail returns the electronic mail as it is, the deletion may be approved.

  When it is confirmed that the image data can be deleted (step S14 / YES), that is, when the deletion approval notification for the electronic mail (notification) is received from the creator of the document 30, the data management unit 114 deletes the data. The unit 114c deletes the image data (step S15). At this time, the data management unit 114 deletes the identification information of the image data from the management table 40 shown in FIG.

  It is also possible to delete without performing the deletion confirmation process. In this case, the deletion may be performed uniformly. For example, when the data management unit 114 includes the deletion confirmation flag in the identification information 31 of the document 30 and confirms that the deletion confirmation flag is off, the deletion information is deleted. Do not perform the confirmation process.

  Thus, by automatically deleting image data of a document whose expiration date has passed, information leakage can be prevented. Further, by confirming execution of deletion before deletion, it is possible to prevent deletion of data that must be stored even if the expiration date has passed.
