In the next step, the authentication print data storage unit 33 generates the print data file 300B having a unique file name within the image forming apparatus 10, so that the authentication print data storage unit 33 stores the authentication print data 300A. Further, the authentication print data storage unit 33 extracts the job name 302, the printing person identification information 303, the print data generation date and time 304, and the print data generation computer name 305 from the authentication print data 300A. Then, the authentication print data storage unit 33 transmits the job name 302, the printing person identification information 303, the print data generation date and time 304, and the print data generation computer name 305 together with the file name of the print data file 300B thus stored to the authentication print data administration unit 34. Accordingly, the authentication print data administration unit 34 additionally stores the records related to the information thus transmitted to the print data administration table 400.
An entire operation of an authentication print system will be explained next with reference to FIG. 2. First, after the computer 100 generates the authentication print data 300A, the authentication print data 300A is transmitted to the image forming apparatus 10 through the network 70.
In the next step, after the authentication print data 300A thus transmitted is authenticated using the RFID card, the image forming apparatus 10 performs the printing operation of the authentication print data 300A. In the embodiment, the computer 100 functions as the web server, to which the computers 100 (=100-1 to 100-3) can access, so that the administrative authority of the authentication print data 300A can be transferred.
In the embodiment, when the administrative authority of the authentication print data 300A is transferred, the information of the authority transferred person and the print data creating person is obtained from the LDAP server 200, and the first mail is transmitted to the SMTP server 201. After the administrative authority of the authentication print data 300A is transferred, when the authentication print data 300A is printed, the second mail is transmitted to the SMTP server 201.
An operation of the software in the computer 100 will be explained next with reference to FIG. 3. When the print application 150 of the computer 100 detects the print instruction from the user, the print application 150 generates the print data with the print data generation unit 143 according to the setting of the authentication print instruction unit 141 of the driver 140. Further, the print application 150 transmits the print data to the image forming apparatus 10 that is specified in advance when the driver 140 is installed.
In the next step, when the authentication print instruction unit 141 specifies the authentication print, the identification information generation unit 142 generates the identification information for specifying an individual, and the identification information is transmitted to the print data generation unit 143. When the print data generation unit 143 receives the identification information, the print data generation unit 143 generates the authentication print data 300A with the individual identification information of the print data creating person attached thereto. The individual identification information may vary depending on an administration procedure, and may include, for example, an login ID, an authentication ID set in advance, an employee number, and a mail address.
An operation of performing the authentication print will be explained next with reference to FIGS. 1 and 5. When the operator performs the authentication print, the operator moves the RFID card over the IC card reader 40 shown in FIG. 1. When the RFID card information reading unit 42 detects that the RFID card moves over the IC card reader 40, the RFID card information reading unit 42 obtains the individual identification information from the RFID card through the USB interface communication unit 41, and transmits the individual identification information to the authentication print authentication unit 43.
In the next step, the authentication print authentication unit 43 determines whether there is the record in the print data administration table 400, in which the individual identification information thus obtained matches to the print data administrator identification information 404, and the IC card reader 401 indicates the print data file 300B with the status “Waiting Authentication State”. When the authentication print authentication unit 43 determines that there is the record, the operation panel control unit 44 displays a confirmation message.
An operation of the image forming apparatus 10 when the image forming apparatus 10 receives the authentication print data 300A will be explained next with reference to FIG. 6. First, as described above, the operation panel display portion 46 displays the job name 402 with the information matched. When the operation panel control unit 44 detects that the enter button 48a indicating the print execution is pushed within a specific period of time since the operation panel display portion 46 displays the job name 402, the operation panel control unit 44 notifies the authentication print data administration unit 34. When the operation panel control unit 44 detects that the cancel button 48c is pushed, or does not detect that the enter button 48a or the cancel button 48a is pushed within the specific period of time since the operation panel display portion 46 displays the job name 402, the image forming apparatus 10 does not perform any operation and returns to the state before the RFID card moves over the IC card reader 40.
In the next step, when the authentication print data administration unit 34 receives the notification of the printing operation from the operation panel display portion 46, the authentication print data administration unit 34 updates the IC card reader 401 from “Waiting Authentication State” to “In Printing State” in the print data administration table 400 shown in FIG. 5. Further, the authentication print data administration unit 34 transmits the print data file 300B with the authentication print data 300A stored therein to the printing unit 35.
In the next step, the printing unit 35 prints the authentication print data 300A thus transmitted on the recording medium. After the printing unit 35 prints the authentication print data 300A on the recording medium, the printing unit 35 transmits a notice that the printing operation is completed and after print information obtained through the printing operation to the authentication print data administration unit 34. The after print information may include, for example, a print start date and time, a print execution sheet number, and a print sheet size.
In the next step, the authentication print data administration unit 34 transmits the administration information administered with the print data administration table 400 of the authentication print data 300A thus printed and the after print information transmitted from the printing unit 35 to the log recording unit 61 and the print completion mail transmission unit 36, respectively.
After the authentication print data administration unit 34 transmits the administration information and the after print information, the authentication print data administration unit 34 deletes the record, in which the information of the authentication print data 300A is stored, from the print data administration table 400. Further, the authentication print data administration unit 34 deletes the print data file 300B with the authentication print data 300A stored therein. In the next step, the log recording unit 61 stores the information received from the authentication print data administration unit 34 to the log file 500. It is noted that the print completion mail transmission unit 36 does not perform any operation after the authentication print data 300A, whose administrative authority is not transferred, is completely printed. Through the process described above, the operator can obtain the print result printed on the recording medium.
An operation of transferring the administrative authority will be explained next. In “Waiting Authentication State”, in which the authentication print data 300A is stored in the image forming apparatus 10, the operator may want to transfer the authority of printing the authentication print data 300A to somebody else. For example, after the operator uses the print application 150 to perform the authentication printing, the operator may request a subordinate or a secretary to print on the recording medium. This is because it may take time to print on the recording medium.
First, the operator uses the web browser 130 of the computer 100 to access to the web server unit 51 of the image forming apparatus 10 where the authentication print data 300A is stored. As a result, the web server unit 51 displays the initial screen 80 as the login authentication screen.
An operation of the initial careen of the web server unit 51 will be explained with reference to FIG. 7. After the ID and the password are input in the ID input field 81 and the password input field 82, when the operator clicks the transmission button 83, the ID input in the ID input field 81 and the password input in the password input field 82 are transmitted to the login authentication unit 52 shown in FIG. 3.
In the next step, the login authentication unit 52 requests the LDAP server 200 to authenticate the ID and the password thus transmitted. When the LDAP server 200 transmits an approval response, the login authentication unit 52 obtains the individual identification information corresponding to the ID and the password from the LDAP server 200, and transmits the individual identification information to the authentication print data display unit 53.
In the next step, referring to the print data administration table 400, the authentication print data display unit 53 obtains the information of the authentication print data 300A, in which the individual identification information is equal to the print data administrator identification information 404, and the IC card reader 401 is “Waiting Authentication Status”. Further, from the administrative authority transfer history table 600, in which the individual identification information of the person whom the print data creating person has transferred the administrative authority before is stored, the authentication print data display unit 53 obtains the individual identification information of the person whom the print data creating person has transferred the administrative authority before, so that the authentication print data display unit 53 generates and transmits the authentication print data list screen 900.
An operation of the authentication print data list screen 900 will be explained with reference to FIG. 8. When the operator clicks the authority transfer execution button 95, the information of the authentication print data 300A selected in a check box 92 and the individual identification information are transmitted to the authority transfer execution unit 54 through the web server unit 51 of the image forming apparatus 10. As described above, the individual identification information to which the administrative authority has been transferred before is selected in the combination box 93, and the individual identification information to which the administrative authority is transferred is input through the input field 94.
An operation of the image forming apparatus 10 for receiving the authentication print data will be explained next with reference to FIG. 9. FIG. 9 is a flow chart showing the operation of the image forming apparatus 10 for receiving the authentication print data according to the first embodiment of the present invention.
In step S61, the authentication print data reception unit 31 receives the authentication print data 300A through the network interface unit communication unit 20. In step S62, the authentication print data analysis unit 32 analyzes the authentication print data 300A to obtain the print data and the individual identification information.
In step S63, the authentication print data storage unit 33 stores the authentication print data 300A in the print data file 300B. IN step S64, the authentication print data administration unit 34 stores the information of the authentication print data 300A in the print data administration table 400, thereby completing the process shown in FIG. 9.
The printing operation of the image forming apparatus 10 will be explained next with reference to FIG. 10. FIG. 10 is a flow chart showing the printing operation of the image forming apparatus 10 according to the first embodiment of the present invention.
In step S70, the RFID card information reading unit 42 obtains the identification information stored in the RFID card. In step S71, the image forming apparatus 10 repeats the process for all data of the print data administration table 400. In step S72, the authentication print authentication unit 43 determines whether the individual identification information of the RFID card matches to the record.
In step S73, the operation panel control unit 44 displays the authentication result on the operation panel display portion 46. In step S74, it is determined whether the enter button 48a is pushed within the specific period of time, indicating that the printing operation is allowed to be performed. When it is determined that the enter button 48a is pushed within the specific period of time, the process proceeds to step S75. When it is determined that the enter button 48a is not pushed or the cancel button 48c is pushed within the specific period of time, the process proceeds to step S81.
In step S75, the printing unit 35 changes the IC card reader 401 of the record to “In Printing State”. In step S76, the printing unit 35 performs the printing operation of the authentication print data 300A.
In step S77, it is determined whether the individual identification information of the RFID card is the authority transferred person. When it is determined that the individual identification information of the RFID card is the authority transferred person, the process proceeds to step S78. When it is determined that the individual identification information of the RFID card is not the authority transferred person, the process proceeds to step S80.
In step S78, the print completion mail transmission unit 36 transmits the mail indicating that the printing operation is completed to the print data creating person mail address 408 and the print data administrator mail address 409 as the authority transferred person. In step S79, the log recording unit 61 stores the information received from the authentication print data administration unit 34 in the log file 500.
In step S80, the authentication print data administration unit 34 deletes the record from the print data administration table 400. In step S81, the authentication print data administration unit 34 repeats the process for all records of the print data administration table 400, thereby completing the process shown in FIG. 10.
An operation of the image forming apparatus 10 for transferring the administrative authority will be explained next with reference to FIG. 11. FIG. 11 is a flow chart showing the operation of the image forming apparatus 10 for transferring the administrative authority according to the first embodiment of the present invention.
In step S10, when the operation starts, the image forming apparatus 10 receives the data of the authentication print data list screen 90 to obtain the information of the authentication print data 300A specified in the check box 92. Further, the image forming apparatus 10 obtains the individual identification information of the authority transferred person, to whom the administrative authority of the authentication print data 300A is to be transferred, specified in the combination box 93 or the input field 94.
In step S11, it is determined whether the individual identification information of the authority transferred person is registered in the LDAP server 200. When it is determined that the individual identification information of the authority transferred person is not registered in the LDAP server 200, it is considered as an input mistake, and the process proceeds to step S12.
In step S12, the error response is transmitted. The error message may be “No specified user registered”. When it is determined that the individual identification information of the authority transferred person is registered in the LDAP server 200, the process proceeds to step S13.
In step S13, the image forming apparatus 10 obtains the individual identification information of the authority transferred person from the LDAP server 200. The individual identification information includes the mail address of the authority transferred person. In step S14, all of the information lists of the authentication print data 300A thus specified is obtained.
In step S15, the process is repeated until all of the authentication print data 300A thus specified is processed. In step S16, it is determined whether the IC card reader 401 related to the authentication print data 300A is “Waiting Authentication State”. When it is determined that the IC card reader 401 related to the authentication print data 300A is not “Waiting Authentication State”, the process proceeds to step S17.
In step S17, the error response is transmitted. The error message may be “the authentication print data 300A is already printed or the administrative authority of the authentication print data 300A is already transferred”. When it is determined that the IC card reader 401 related to the authentication print data 300A is “Waiting Authentication State”, the process proceeds to step S18.
In step S18, the image forming apparatus 10 obtains the information of the print data creating person identification information 403 of the authentication print data 300A from the print data administration table 400. In step S19, the image forming apparatus 10 obtains the mail address of the print data creating person identification information 403 from the LDAP server 200 according to the information of the print data creating person identification information 403.
In step S20, the image forming apparatus 10 changes the print data administrator identification information 404 of the record to the individual identification information of the authority transferred person.
In step S21, the image forming apparatus 10 changes the print data creating person mail address 408 of the record to the mail address of the print data creating person obtained from the LDAP server 200.
In step S22, the image forming apparatus 10 changes the print data administrator mail address 409 of the record to the mail address of the authority transferred person obtained from the LDAP server 200.
In step S23, the image forming apparatus 10 stores the individual identification information of the print data creating person identification information 403 obtained from the LDAP server 200 and the individual identification information of the authority transferred person obtained from the LDAP server 200 to the administrative authority transfer history table 600. Accordingly, when administrative authority is transferred next time, it is possible to easily input the individual identification information.
In step S24, the image forming apparatus 10 notifies the information of the print data administration table 400 to the authority transfer mail transmission unit 55. When the authority transfer mail transmission unit 55 receives the notification, the authority transfer mail transmission unit 55 generates an electric mail as the first mail, and transmits the first mail to the SMTP server 201. In the first mail, the print data creating person mail address 408 and the print data administrator mail address 409 are included in destinations “Bcc:” thereof, and the information of the authentication print data 300A notified from the authority transfer execution unit 54 is converted in a specific format. As a result, any person having the print data administrator mail address 409 can access to the SMTP server 201 to receive the first mail.
In step S25, the process returns to step S15 until all of the authentication print data 300A thus specified is processed. In step S26, the authentication print data display unit 53 displays the authentication print data list screen 90 after the update, thereby completing the operation shown in FIG. 11.
In the operation shown in FIG. 11, the information of the authentication print data 300A is notified through the electric mail as the first mail to the person who creates the authentication print data 300A and the person to whom the administrative authority of the authentication print data 300A is transferred. The first mail is transmitted so that the person to whom the administrative authority of the authentication print data 300A is transferred is notified of the fact. Further, when the administrative authority of the authentication print data 300A is transferred to the third party from the person to whom the administrative authority of the authentication print data 300A is transferred, the person who creates the authentication print data 300A can confirmed that the administrative authority of the authentication print data 300A is transferred.
FIG. 12(a) is a schematic view showing the print data administration table 400 before the administrative authority is transferred according to the first embodiment of the present invention. FIG. 12(b) is a schematic view showing the print data administration table 400 after the administrative authority is transferred according to the first embodiment of the present invention.
As shown in FIG. 12(a), the print data administration table 400 includes the record representing the authentication print data 300A in which the job name 402 is “JobName3”. The person who creates the print data is “User1”. It is supposed that according to the instruction of the person “User1”, the administrative authority of the authentication print data 300A is transferred to a person “User3”.
FIG. 12(b) is the schematic view showing the record of the print data administration table 400 after the administrative authority is transferred. As shown in FIG. 12(b), after the administrative authority is transferred, the record related to the authentication print data 300A is changed.
More specifically, the print data administrator identification information 404 of the record is changed to the individual identification information of the authority transferred person. Further, the print data creating person mail address 408 of the record is changed to the mail address of the print data creating person identification information 403 obtained from the LDAP server 200. Further, the print data administrator mail address 409 of the record is changed to the mail address of the authority transferred person obtained from the LDAP server 200.
In the embodiment, after the print data administration table 400 is updated, when the RFID card having the individual identification information of the authority transferred person is moved over the IC card reader 40, the authentication printing is performed. After the authentication printing is performed, the information of the authority transferred person is recorded in the log file 500 as the person who performs the authentication printing.
Accordingly, both of the individual identification information of the print data creating person and the individual identification information of the person who performs the authentication printing are recorded in the log file 500. As a result, if a security accident happens, it is possible to identify both the print data creating person and the person who performs the authentication printing through a tracking investigation.
In the embodiment, after the administrative authority is transferred, in the record, the mail addresses are stored in the print data creating person mail address 408 and the print data administrator mail address 409, respectively. Accordingly, it is possible to determine whether the administrative authority is transferred.
In the embodiment, when the authentication print data 300A with the administrative authority thereof transferred is printed, the print completion mail transmission unit 36 transmits an electric mail as the second mail to the SMTP server 201. In the second mail, the print data creating person mail address 408 and the print data administrator mail address 409 are included in the destinations “Bcc:” thereof. The information of the authentication print data 300A after the authentication printing is performed and the after print information are converted in a specific format to create a main text of the second mail.
In the embodiment, when the administrative authority is not transferred, in the record, nothing is stored in the print data creating person mail address 408 or the print data administrator mail address 409. Accordingly, the print completion mail transmission unit 36 does perform nothing.
As described above, the image forming apparatus 10 includes the web server unit 51. When the operator operates the web browser 130 of the computer 100, it is possible to transfer the administrative authority of the authentication print data 300A. In other words, the operator can perform the printing operation of the application and the transfer operation of the administrative authority after the printing operation using the same computer 100. Accordingly, the operator does not need to leave from the computer 100, thereby improving operation efficiency.
In the embodiment, in the image forming apparatus 10, when the administrative authority of the authentication print data 300A is transferred, the operator operates the web browser 130 to display the authentication print data 300A stored therein and input the individual identification information of the person to whom the administrative authority is transferred. Accordingly, even when the image forming apparatus 10 is provided with the operation panel display portion 46 having a small size and a small input unit with only a few buttons for inputting the information, it is possible to efficiently input the information.
FIG. 13 is a schematic view showing the first mail to be transmitted from the image forming apparatus 10 when the administrative authority is transferred according to the first embodiment of the present invention.
As shown in FIG. 13, “Printer” is displayed in “From:” indicating the origination address of the first mail.

Further, the main text of the first mail includes “This mail is sent from Printer. The administrative authority of the following authentication print is transferred from User1 to User3 Date: 2010/10/02 17:25:37 Apparatus: Printer Document: AuthDocument.text”.
FIG. 14 is a schematic view showing the second mail to be transmitted from the image forming apparatus 10 when the printing operation is completed according to the first embodiment of the present invention.
As shown in FIG. 14, “Printer” is displayed in “From:” indicating the origination address of the second mail. Nothing is displayed in “To:” indicating the destination address of the second mail, and “Cc:” indicating the destination address of the copy. In “Bcc:” indicating the non-displayed destination address of the copy, “User1_Print data creating person<User1@XXXX.jp>” and “User3_Administrative authority transferred person<User3@XXXX.jp>” are displayed. “Completion notification of authentication print” is displayed in “Title:” indicating the subject of the second mail.
Further, the main text of the second mail includes “This mail is sent from Printer. The authentication print data with the administrative authority thereof transferred from User1 to User 3 is completed Date: 2010/11/02 11:01:00 Apparatus: Printer (XXX.XXX.XXX.XXX) Printing person: User3 Document: AuthDocument.text Printed sheet number: 50”.
In the embodiment, with the image forming apparatus 10 and the method of transferring the administrative authority of the authentication print data 300A, it is possible to obtain the following effects. First, after the operation of the authentication print is performed on the computer 100, it is possible to safely transfer the administrative authority of the authentication print data 300A to the specific user.
Second, the image forming apparatus 10 includes the web server unit 51. When the web browser 130 is operated through the computer 100, it is possible to transfer the administrative authority of the authentication print data 300A. Accordingly, it is possible to perform the printing operation of the application and the transfer operation of the administrative authority after the printing operation using the same computer 100. Accordingly, the operator does not need to leave from the computer 100, thereby improving operation efficiency.
Third, the image forming apparatus 10 includes the web server unit 51. When the administrative authority of the authentication print data 300A is transferred, the web browser 130 of the computer 100 is used for displaying the authentication print data 300A stored therein and inputting the individual identification information of the administrative authority transferred person. Accordingly, even when the image forming apparatus 10 is provided with the operation panel display portion 46 having a small size and a small input unit with only a few buttons for inputting the information, it is possible to efficiently input the information.

In the next step, similar to the first embodiment, the authentication print data administration unit 34 stores “Waiting Authorization State” in the IC card reader 401. Further, the authentication print data administration unit 34 stores the job name related to the authentication print data 300A in the job name 302, and stores the printing person identification information 303 in the print data creating person identification information 403. Further, the authentication print data administration unit 34 stores the printing person identification information 303 in the print data administrator identification information 404, and stores the print data generation date and time 304 in the print data generation date and time 405. Further, the authentication print data administration unit 34 stores the print data generation computer name 305 in the print computer name 406, and stores the file name under which the authentication print data 300A is stored in the print data file name 407. It is noted that the authentication print data administration unit 34 stores nothing in the print data creating person mail address 408 and the print data administrator mail address 409.
In the embodiment, the print data is deleted from the print data administration table 400 after the printing operation is completed. When only the record is deleted, “0” is stored in the print data deletion process flag 410. When all records having the print data file name 407 are deleted, “1” is stored in the print data deletion process flag 410. It is noted that the initial value of the IC card reader 401 is “0” when the record is generated.
In the second embodiment, similar to the first embodiment, when the print data creating person performs the printing operation, the RFID card moves over the IC card reader 40 for the authentication. After the printing operation is completed, the authentication print data administration unit 34 determines the value of the print data deletion process flag 410 with reference to the record, whose printing operation is completed, from the print data administration table 400.
In the embodiment, when the authentication print data administration unit 34 determines that “0” is stored in the print data deletion process flag 410, only the record is deleted. When there is no other records having the print data file name 407 the same as that stored in the print data file name 407 of the record thus deleted, the authentication print data administration unit 34 deletes the print data file 300B.
In the embodiment, when the authentication print data administration unit 34 determines that “1” is stored in the print data deletion process flag 410, the authentication print data administration unit 34 obtains the print data file name 407 of the record. Then, the authentication print data administration unit 34 deletes all records having the print data file name 407 with the same contents of the print data file name 407 of the record thus obtained. Further, the authentication print data administration unit 34 deletes the print data file 300B.
In the second embodiment, similar to the first embodiment, the log recording unit 61 stores the information received from the authentication print data administration unit 34 in the log file 500.
