Description

  The present invention relates to a system related to printing performed in an office, a school, or the like, and more particularly, to a system for illegally taking out printed materials that prohibits third parties from illegally taking out printed materials.

  In offices, schools, and the like, printing is performed with a printer on a daily basis, but the installation location of the printer is often physically separated from the terminal that issues the print instruction. For this reason, there is a possibility that a printed matter may be illegally taken out by a third party other than the user who has given the print instruction, which is problematic in terms of security. In order to cope with such a problem, a mechanism is considered in which a user who gives a print instruction starts printing after coming in front of the printer. Examples of such a mechanism include Patent Documents 1 and 2.

  In Patent Document 1, authentication information is assigned to each print instruction and transmitted to the printer, and the same authentication information is stored in the IC card. Then, when the user who gives the print instruction holds the IC card over the printer, the printer collates the authentication information, and if the collation result is correct, printing is started.

In Patent Document 2, in addition to the mechanism of Patent Document 1, printing is performed only while an IC card (authentication card in Patent Document 2) is inserted into the card reader device.

As shown in FIG. 7, when the user uses the terminal 7, the user holds the IC card 19 over the IC card reader / writer 17 connected to the terminal 7, and the terminal 7 holds the IC card 19 over the terminal 7. Authentication is performed and a user ID is acquired (step 301). The authentication process may be performed by the IC card reader / writer 17.
Next, the terminal 7 checks whether there is a print instruction (step 302).
If there is a print instruction, the first print ID is automatically numbered (step 303).
Next, the terminal 7 transmits the print command data 101 including the user ID 103, the first print ID 105, and the print data 107 to the printer server 9 (step 304).

  The printer server 9 stores the print command data 101 as the print job data 201 (step 305). Here, the printer server 9 may perform automatic numbering so that the first print ID 205 of the print job data 201 is a number or a symbol that uniquely identifies the print job data 201. The printed flag 211 is set to off.

FIG. 8 is a flowchart showing the procedure for entering the printer area.
As shown in FIG. 8, when the user enters the printer area 5, the user holds the IC card 19 over the IC card reader / writer 17 of the first gate 11, and the first gate 11 moves to the IC card 19. , Authentication is performed and a user ID is acquired (step 401). The authentication process may be performed by the IC card reader / writer 17.
Next, the first gate 11 transmits the user ID to the printer server 9 (step 402).

The printer server 9 searches for the first print ID 205 of the print job data 201 (step 403). That is, the first print ID 205 of the corresponding print job data 201 is searched using the user ID transmitted from the first gate 11 as a search key.
Next, the printer server 9 transmits a list of first print IDs 205 to the first gate 11 (step 404). Here, the printer server 9 may determine the presence or absence of the first print ID 205 and transmit information indicating whether or not to unlock to the first gate 11.

The first gate 11 checks whether there is a first print ID 205 (step 405).
If there is no first print ID 205, the user notification device 69 of the first gate 11 notifies the user that entry is not permitted (step 406), and if there is the first print ID 205, the process proceeds to step 407.
Next, the first gate 11 requests the printer server 9 to select the printer 15 that performs printing (step 407).

The printer server 9 selects the printer 15 that performs printing (step 408).
Next, the printer server 9 transmits printer information for printing to the first gate 11 (step 409).

The user notification device 69 of the first gate 11 notifies the user of the printer 11 that performs printing (step 410).
Next, the gate opening / closing control device 65 of the first gate 11 unlocks the gate device 63 (step 411).

FIG. 9 is a flowchart showing a procedure for executing printing.
As shown in FIG. 9, when the user uses the printer 15, the user holds the IC card 19 over the IC card reader / writer 17 connected to the printer 15, and the printer 15 holds the IC card 19 over it. Authentication is performed and a user ID is acquired (step 501). The authentication process may be performed by the IC card reader / writer 17.
Next, the printer 15 transmits the user ID to the printer server 9 (step 502).

The printer server 9 searches the print job data 201 (step 503). That is, the corresponding print job data 201 is searched using the user ID transmitted from the printer 15 as a search key.
Next, the printer server 9 transmits a list of print job data 201 to the printer 15 (step 504).

The printer 15 displays a list of the first print IDs 205 of the print job data 201 on the screen (step 505). Here, it is desirable to display the document information to be printed, for example, the file name, etc., together with the first print ID 205. In addition, it is desirable that a print job can be deleted as desired by the user.
After the user determines the first print ID 205 to be printed, the printer 15 assigns the first print ID 205 to the printed matter and prints (step 506). In other words, the printer 15 assigns the same information as the first print ID 205 determined by the user to the printed material as the second print ID, and the print target related to the print job data 201 including the first print ID 205 determined by the user. Data 108 is printed.
Here, in addition to the first print ID 205, a number or a symbol that uniquely identifies the printer 15 may be assigned so that the printer can be identified.
For example, the print ID is given by putting a second print ID into an RFID tag of a printed material, or attaching an RFID tag label, a barcode label or a two-dimensional code label indicating the second print ID to the printed material, or a printed material. Is to print a bar code or a two-dimensional code indicating the second print ID.
Next, the printer 15 transmits the first print ID 205 that has been printed to the printer server 9 (step 507).
Since printing may be incomplete due to out of paper or the like, it is desirable to transmit the first print ID 205 to the printer server 9 after all pages have been printed.

  The printer server 9 updates the printed flag 211 of the corresponding print job data 201 to ON (step 508). That is, the print completion flag 211 of the print job data 201 related to the first print ID transmitted from the printer 15 is updated to ON.

The printer 15 deletes the first print ID 205 updated with the printed flag 211 turned on from the list (step 509).
The printer 15 confirms whether all printing has been completed (step 510).
If all printing has been completed, the process is terminated. If all printing has not been completed, the process is repeated from step 506.
Here, when communication between the IC card reader / writer 17 and the IC card 19 connected to the printer 15 is interrupted and a printed matter remains on the tray of the printer 15, the printer 15 generates a warning sound. You may make it notify that there is forgetting.

FIG. 10 is a flowchart showing a procedure for leaving the printer area.
As shown in FIG. 10, when the user leaves the printer area 5, the user holds the IC card 19 over the IC card reader / writer 17 of the first gate 11, and the first gate 11 moves to the IC card 19. , Authentication is performed and a user ID is acquired (step 601). The authentication process may be performed by the IC card reader / writer 17.
Next, the first gate 11 transmits the user ID to the printer server 9 (step 602).

The printer server 9 searches for the first print ID 205 of the print job data 201 (step 603). That is, the first print ID 205 of the corresponding print job data 201 is searched using the user ID transmitted from the first gate 11 as a search key.
Next, the printer server 9 transmits a list of the first print IDs 205 to the first gate 11 (step 604). Here, the printer server 9 may perform a first unlocking determination to be described later and transmit information indicating whether or not to unlock.

The print ID acquisition device 67 for the printed material of the first gate 11 acquires the second print ID assigned to the printed material (step 605).
To obtain the second print ID, the method of assigning the first print ID 205 to the printed material uses an RFID tag reader / writer when using an RFID tag, and uses a barcode reader when using a barcode. When a two-dimensional code is used, a two-dimensional code reader is used.
Next, the first gate 11 determines whether to unlock according to the first print ID 205 transmitted from the printer server 9 and the second print ID assigned to the printed material (step 606). That is, the unlocking determination at the time of exit is performed by the first unlocking determination unit at the time of exit.

The first unlocking determination at the time of leaving is determined as unlocking when the first print ID 205 in which the printed flag 211 is set to ON matches the second print ID assigned to the printed material without excess or deficiency. You may do it.
The first exit unlocking determination means calculates the number of prints for each first print ID 205, obtains the number of prints for each second print ID assigned to the printed matter, and performs the first printing. When the number of printed sheets for each ID 205 and the number of printed sheets for each second print ID coincide with each other without excess or shortage, it may be determined that the lock is unlocked.
Here, the number of prints for each first print ID 205 is obtained by multiplying the number of copies 109 included in the print data 107 of the print command data 101 by the number of pages 111 per copy.
Furthermore, the number of printed sheets for each second print ID is obtained by counting the actual number of printed materials by obtaining the second print ID assigned to the printed materials for all printed materials. In order to prevent the same printed material from being counted twice, information for identifying printed materials having the same second print ID, for example, a page number and a copy number, are also given to the printed material together with the second print ID. It is desirable that

The first gate 11 determines whether or not to unlock from the determination result by the first exit unlocking determination means (step 607).
When unlocking is not performed, the user notification device 69 of the first gate 11 notifies the user that the exit is not permitted (step 608).
When unlocking, the gate opening / closing control device 65 of the first gate 11 unlocks the gate device 63 (step 609).

FIG. 11 is a flowchart illustrating a procedure for determining whether to accept a print command.
The print command acceptance determination process is a process performed in step 305 of the flowchart showing the procedure of the print instruction shown in FIG.
As shown in FIG. 11, the printer server 9 checks whether or not the print command data 101 has been received (step 701).
If there is reception, the printer server 9 calculates the number of printed sheets (step 702). Here, the number of prints is obtained by multiplying the number of copies 109 included in the print data 107 of the print command data 101 by the number of pages 111 per copy. Note that the terminal 9 may transmit the number of prints as the print data 107 of the print command data 101.
Next, the printer server 9 adds the calculated number of printed sheets to the total number of printed sheets of the print job data 201 having the same user ID (step 703).
Here, the total number of print jobs of the print job data 201 with the same user ID is the number of prints 109 included in the print data 207 of the print job data 201 and the number of pages per copy for each first print ID 205 that has not been printed. 111 is multiplied to obtain the number of printed sheets, and the total number of printed sheets is obtained.
Next, the printer server 9 checks whether or not the total number of printed sheets exceeds the threshold value (step 704).
If the threshold value is not exceeded, the printer server 9 stores the received print command data 101 as print job data 201 (step 705).
If the threshold is exceeded, the process is terminated. That is, the print command data 101 is not received and is not stored as the print job data 201.

FIG. 12 is a flowchart illustrating a procedure for deleting a print job.
The print job deletion process is a process performed immediately before step 407 in the flowchart showing the procedure for entering the printer area in FIG.
As shown in FIG. 12, the first gate 11 acquires the latest reception time 209 in the print job data 201 related to the same user ID from the printer server 9 (step 801).
Next, the first gate 11 calculates the elapsed time (step 802). That is, the time from the most recent received time 209 acquired to the current time is calculated.
Next, the first gate 11 checks whether or not the elapsed time exceeds the threshold (step 803).
If the threshold is not exceeded, the admission process is continued (step 804).
When the threshold value is exceeded, the user notification device 69 of the first gate 11 notifies the user that entry is not permitted (step 805).
Next, the first gate 11 transmits an instruction to delete all the print job data 201 related to the same user ID to the printer server 9 (step 806). By this command, the printer server 9 deletes all the print job data 201 related to the same user ID. That is, the user cannot enter the printer area 5 unless he / she issues a print instruction again.

As described above in detail, according to the unauthorized unauthorized printing export system 1 according to the embodiment of the present invention, when the user enters the printer area 5, the unlocking determination is performed based on the presence or absence of the print job data 201. By restricting the number of users who enter, illegally taking out printed matter can be prevented in advance.
Further, when the user leaves the printer area 5, the third party determines the unlocking according to the first print ID 205 of the print job data 201 and the second print ID assigned to the printed material, so that the third party can remove the printed material. Unauthorized take-out can be prohibited.
In the unlocking determination, the first print ID 205 with the printed flag 211 set to ON is compared with the second print ID assigned to the printed material, and the printed material actually printed is taken out. By determining whether the printed materials match without excess or deficiency, it is possible to accurately manage the taking-out of the printed materials. Further, the unlocking determination can detect misplacement of printed matter by comparing the number of printed sheets.

In addition, when a print command is received, a threshold is set for the total number of prints for each user, and even if a malicious user attempts to leak information, the damage is minimized by preventing the act of printing in large quantities at once. Can stop.
Further, when entering the printer area 5, if the elapsed time from the reception time of the print command exceeds the threshold value, the entry is not permitted, and all the print jobs are deleted. Even when a person abuses an IC card, it is a certain prevention.

  Next, the second embodiment will be described in detail.

  Next, the details of the operation of the printed matter unauthorized take-out prohibiting system 1a will be described with reference to FIG. 15 and FIG.

FIG. 15 is a flowchart showing a procedure for determining whether to unlock at the time of leaving the high security in the first gate 11.
The high-security exit unlocking determination process in the first gate 11 is a process performed immediately after step 605 in the flowchart showing the procedure for exiting the printer area in FIG. 10 described above.

As shown in FIG. 15, the first gate 11 acquires the importance of the printed material from the printer server 9 (step 901).
Next, the first gate 11 checks whether the importance of the printed material is important (step 902).
If not important, the exit process is continued (step 903). That is, processing is performed from step 605 of the flowchart showing the procedure for exiting the printer area in FIG.
If it is important, the user notification device 69 of the first gate 11 notifies the user to leave at the second gate 13 (step 904).

  FIG. 16 is a flowchart showing the procedure for determining whether to unlock at the time of leaving the high security in the second gate 13.

As shown in FIG. 16, when the user leaves the printer area 5 from the second gate 13, the user holds the IC card 19 over the IC card reader / writer 17 of the second gate 13 and the second gate 13. 13, when the IC card 19 is held over, authentication is performed and a user ID is acquired (step 1001). The authentication process may be performed by the IC card reader / writer 17.
Next, the second gate 13 transmits the user ID to the printer server 9 (step 1002).

The printer server 9 searches for the first print ID 205 of the print job data 201 (step 1003). That is, the first print ID 205 of the corresponding print job data 201 is searched using the user ID transmitted from the second gate 13 as a search key.
Next, the printer server 9 transmits a list of first print IDs 205 to the second gate 13 (step 1004).

The user notification device 69 of the second gate 13 notifies the user that the image data of all printed materials and the second print ID assigned to the printed materials are acquired (step 1005).
Next, the printed image data acquisition device 71 of the second gate 13 acquires the printed image data (step 1006).
Next, the second gate 13 acquires the second print ID assigned to the printed material (step 1007).
Next, the second gate 13 stores the image data of the printed matter and the second print ID as a processing log (step 1008). Note that the second gate 13 may transmit the image data of the printed matter and the second print ID to the printer server 9, and the printer server 9 may store the processing log.

The second gate 13 checks whether or not the image data and the second print ID have been stored for all pages (step 1009). In other words, the unlocking determination at the time of exit is performed by the second unlocking determination unit at the time of exit. Specifically, the number of prints for each first print ID 205 is calculated based on the number of prints 109 calculated from the first print ID 205 of the print job data 201 and the number of prints 109 included in the print data 207 and the number of pages 111 per copy. Check if the process log has been saved.
Here, when the printer server 9 saves the processing log, the printer server 9 confirms whether or not all pages have been completed, and transmits to the second gate 13 whether to continue the exit processing. May be.
If all pages have not been completed, the process is repeated from step 1006.
If all pages are finished, the exit process is continued (step 1010). That is, processing is performed from step 605 of the flowchart showing the procedure for exiting the printer area in FIG.
