Description

Outputting method and system of outputted documents inserted QR code}

The present invention uses the image forming apparatus (hereinafter referred to as a 'multiplexer') having a complex function of copying, scanning, or faxing to perform output (copy / scan / fax transmission, etc.) of a QR code-inserted output. Method and system, in particular, according to the output request of the user to cut and read the QR code inserted in the output, based on the QR code information read (extracted), the QR code inserted output (security document, etc.) The present invention relates to a method and a system for outputting an output having a QR code inserted therein.

In general, an image forming apparatus includes functions such as copying, printing, scanning of a fax (fax) or original (document, etc.) and a box function.

Such a device having a complex output function is called a multi function printer (MFP). In other words, the multifunction device not only functions as a printer for printing data input from a host computer (e.g., a user's PC), but also functions as a scanner for scanning image documents, and a digital copy function for printing and copying scanned and scanned image documents, It is a machine with a compound document output function that performs a facsimile (fax) function for transmitting image originals to a remote place through a communication line.

In other words, it is a multi-functional terminal that integrates existing terminal devices such as facsimile machines, scanners, printers, and digital copiers, and has a host computer-interface function that works with a host computer. In many cases, multiple multifunction devices (image forming apparatuses) are connected to each other.

On the other hand, in recent years, as the work environment changes to an environment using a computer, a communication network, and the Internet, efforts to protect confidential data such as important documents and drawings from theft, leakage, and loss have been greatly increased. For example, in order to establish an optimal security system in a work environment in which documents are printed or various tasks are performed through a communication network, and the documents necessary for security are output to a printer connected to a network, many companies have printed outputs. I use a security system.

A group or group of companies (hereinafter referred to as a company) gathered for any purpose, such as a company or group, only sees so-called confidentiality that is confidential to a person who is not a member of the company for the benefit of the company, and only certain authorized members of the company. And editing is possible. Documents containing one or more of these items are collectively referred to as security documents.

In general, in case of secure document, when printing to company printer, who printed what document with ID and IP registered on the server, the document is printed in light gray with own affiliation, print time and name. So-called watermarks are printed together. Most companies use only these two methods for document security.

However, unless you carefully monitor each one of the members of the company, using only the above method has a disadvantage that is very vulnerable to the export of documents. Since the leakage of confidentiality directly affects the damage, such as the loss of the company, a stronger document security method is needed in addition to the above method.

In addition, even relatively insecure documents are made indiscriminately in the company, so that other users and departments can be viewed in the company except for specific users and departments. Can be generated.

The management server 30 is connected to the authentication terminal 40 to authenticate the user, and is connected to the relay server 20 and the multifunction apparatus (image forming apparatus) 50 to manage the history of the system.

Specifically, the management server 30 of the present invention is the authentication processing unit 37, history management unit 34, the third transmission and reception unit 32, multi-function state management unit 33, the third storage unit 35, the third input And an output unit 36 and a third control unit 31.

The authentication processing unit 37 cooperates with the authentication terminal 40 to process authentication for the user. Since authentication is made in the description of FIG. 3, it will be omitted.

The history management unit 34 is configured between the management server 30 and a device (i.e., relay server 20, authentication terminal 40, multifunction apparatus (image forming apparatus) 50, etc.) associated with the management server 30. The history is managed, and the history information is stored in the third storage unit 35.

The all-in-one state management unit 33 checks the state of the all-in-one (image forming apparatus) 50 (for example, power on / off, in use, waiting for use, etc.) to check the multifunction apparatus (image forming apparatus) at any time. The management unit 50 is managed, and the state information of the multifunction apparatus (image forming apparatus) 50 is stored in the third storage unit 35.

As an example, the third input / output unit 36 may be implemented by a touch method.

Next, the QR code inserted in the output (document, etc.) will be described in detail.

6A to 6D are diagrams illustrating outputs in which a QR code is inserted (printed) according to an embodiment of the present invention.

6A to 6D, it can be seen that one or more QR codes are inserted (printed) in the output (document, etc.).

 Preferably, one to four QR codes are inserted (printed) for each page (page, side) of the output (document, etc.), and up to nine QR codes can be inserted (printed).

In FIG. 6A, one QR code is inserted (printed) for each page (page, surface) of the output (document, etc.). Specifically, one QR code is inserted (printed) in the upper left of the output (document, etc.).

In addition, in FIG. 6B, two QR codes are inserted (printed) for each page (page, surface) of the output (document, etc.). Specifically, one QR code is inserted (printed) in the upper left and lower right of the output (document, etc.).

In addition, in FIG. 6C, three QR codes are inserted (printed) for each page (page, surface) of the output (document, etc.). Specifically, one QR code is inserted (printed) in the upper left, upper right and lower left of the output (document, etc.).

In addition, in FIG. 6D, four QR codes are inserted (printed) for each page (page, surface) of the output (document, etc.). Specifically, one QR code is inserted (printed) in the upper left, upper right, lower left and lower right of the output (document, etc.).

Further, a watermark may be further formed on the output (document, etc.), which watermark is preferably formed between the QR codes.

This QR code is embedded with QR code information 80 including security information (security information value) indicating whether the output (document, etc.) of the output (copy, scan, or fax transmission) is enabled (enabled or disabled). In other words, an electronic code having security information 83 as code information is generated in the QR code.

6E is a structural diagram of QR code information 80 to be included in the QR code of the present invention.

6A to 6E, QR code information 80 to be included in a QR code includes a QR code generation time 81, a UUID 82, security information 83, an output limit number 84, and a user name 85. ), Pattern codes, and the like, and are separated by semicolons (;) as an example.

The QR code generation time 81 indicates the time when the QR code is generated in the output. For example, the QR code generation time 81 may be displayed as the year, month, day, hour, minute, and second. In FIGS. 6A to 6D, '2018-12-14 18:12:32 second' It is indicated as

The UUID (Universally Unique IDentifier) 82 is generated for each output (document, etc.) for the output (document, etc.) when the QR code is generated (inserted) in the output, and the corresponding output with the QR code inserted therein. This identifier is automatically generated each time output (copy, scan, fax transmission, etc.) is performed for a document. That is, one original QR UUID is generated per page (one side) of one output (document, etc.), and a copy UUID is generated each time the original QR UUID is output (copy / scan / fax). In addition, the UUID 82 may be represented by 36 digits as an example, and is represented as '1b5a2c97-38d1-4592-9cdc-ba17fff7ffba' in FIGS. 6A to 6D.

The security information (security information value) 83 is information indicating whether output (copying / scanning / faxing) of user-specific / departmental outputs (documents, etc.) is possible (printable or non-printable). (zero) 'or' 1 '.

For example, if the security information (security information value) is marked as '0', the user or department indicates that the output (copy / scan / fax transmission) for the output (document, etc.) is possible, and the security information (security Information value) indicates that the user or department cannot output (copy / scan / fax) to the output (document, etc.).

In FIGS. 6A to 6D, the security information (security information value) is denoted by the number '1', which indicates that the user or department cannot output (copy / scan / fax) to the output (document, etc.). Indicates.

Security information (security information value) indicating whether output (copying / scanning / faxing) of the corresponding output (document, etc.) by user / department is available (copying or copying impossible) is set and managed by the administrator.

The output limit number 84 indicates the limit number of times of output (copy / scan / fax transmission) of the output (document, etc.). As an example, when the output limit number 84 is set to '5' as shown in Figs. 6A to 6D, it indicates that output (copy / scan / fax transmission) of the output (document or the like) is possible up to five times. That is, when the output (copy / scan / fax) of the output (document, etc.) is the sixth, no further output (copy / scan / fax transmission) is possible for the output (document, etc.). The result will be changed to 'No'. The output (copy / scan / fax transmission) for the corresponding output (document, etc.) is no longer made. Such history information can be displayed and managed through a web page.

Specifically, each time the output (copy / scan / fax transmission) for the output (document, etc.) is performed, the output count is also updated in the history information. The result will be changed to 'No output' at. After that, if you try to output the output (documents, etc.) no further output is made.

The output limit count value is specified (set) in advance by an administrator. As an example, when the output limit count value is set to '5' as the default value by the administrator, a QR code insertion and generation request by the user is requested. According to the QR code generation according to the 'output limit count value' of the QR code information 80 is automatically generated (recorded) as '5'.

By limiting the number of outputs in this way, the security against indiscriminate copying can be prevented.

On the other hand, the reason for not being able to output is not only the number of output limitations described above, but also QR code recognition (reading) is not possible, QR code count check failure, some QR code recognition (reading) failure, user ID mismatch, UUID when combining pattern codes And mismatch with (82), and QR pattern mismatch.

Among the reasons for not being able to print, 'No QR code recognition (reading)' corresponds to a case where the QR code is not recognized (reading) when the QR code reader attempts to read (read) the QR code.

Among the reasons for not being able to print, 'Failed to check the number of QR codes' or 'Failed to read some QR codes' means that one or more QR codes are not read when the QR code is read using a QR code reader. . For example, although all four QR codes shown in FIG. 6D should be recognized, only three or less QR codes are recognized.

Among the reasons for not being able to print, 'user ID mismatch' corresponds to a case where the user (or user ID) in the QR code information 80 and the user (or user ID) who logged in the multifunction apparatus (image forming apparatus) 50 do not match. do. In some cases, it may be possible to exclude (not include) the 'User ID Mismatch' among the reasons for not being able to print.

Among the reasons for non-printing, 'unmatched UUID 82 when combining pattern codes (abbreviatedly, pattern code mismatch)' will be described in detail below, but it does not coincide with UUID 82 when combining pattern codes of QR codes. If not. In the present invention, when the pattern codes of the QR codes are combined, it is normal to match the UUID 82, and when it does not match the UUID 82, it corresponds to an abnormality (bad or impossible output).

In the present invention, the result value is displayed as 'output enabled' or 'not outputable' in the history information, which is displayed on a web page on the Internet.

In this case, if the output can be outputted, the result value of the history information is displayed as 'output enabled'. If the output is not possible, the result value of the history information is marked as 'not outputable' and the output described above. Impossibility may be indicated together.

In the QR code information 80, the user ID 85 may be a user ID. For example, the user name 85 may be inputted as 'yspark9' in FIGS. 6A to 6D.

In the embodiment of the present invention, for each page of the output (document, etc.) as an example, two to four QR codes are inserted and printed as shown in Figs. 6B to 6D, for the purpose of distinguishing the two to four QR codes. Pattern codes 86 are formed, respectively. That is, the pattern code to be included in each QR code is different depending on the number of QR codes.

As an example, assuming that four QR codes are formed on each page of the printout as shown in FIG. 6D, the four QR codes are respectively represented by 'QR code 1', 'QR code 2', 'QR code 3' and 'QR code 4'. And the pattern codes of the QR code information 80 in each of the QR codes (QR codes 1 to QR code 4) are also referred to as' pattern code 1 ',' pattern code 2 ',' pattern code 3 'and' You might call it pattern code 4 '. Specifically, QR code 1 represents a QR code located at the top left of the output among four QR codes, QR code 2 represents a QR code located at the top right of the printed output among the four QR codes, and QR code 3 represents four QR codes. The QR code is located at the bottom left of the printout, and the QR code 4 represents the QR code located at the bottom right of the printout. In addition, pattern code 1 represents the pattern code of the QR code information 80 in the QR code 1, pattern code 2 represents the pattern code of the QR code information 80 in the QR code 2, and pattern code 3 represents the code code in the QR code 3 The pattern code of the QR code information 80 is shown, and the pattern code 4 represents the pattern code of the QR code information 80 in the QR code 4.

In this case, when the pattern code 1, the pattern code 2, the pattern code 3, and the pattern code 4 are combined in this order, the UUID 82 is matched in the normal case, and the UUID 82 is mismatched in the abnormal case. The combination of these pattern codes can be set by the administrator.

Specifically, as shown in FIG. 6D, pattern code 1 of QR code 1 is '1b5a2c97-', pattern code 2 of QR code 2 is '38d1-4592', and pattern code 3 of QR code 3 is '-9cdc'. -ba1 ', and pattern code 4 of QR code 4 is' 7fff7ffba'. Combining these pattern noses sequentially will result in '1b5a2c97-38d1-4592-9cdc-ba17fff7ffba', which is consistent with the UUID 82. As a result of the QR code reading, this QR code is determined to be a normal QR code.

As another example, assuming that three QR codes are formed on each page of the printout as shown in FIG. 6C, the three QR codes are named 'QR code 1', 'QR code 2' and 'QR code 3', respectively. The pattern codes of the QR code information 80 in each of the QR codes (QR codes 1 to QR code 3) may also be referred to as 'pattern code 1', 'pattern code 2' and 'pattern code 3', respectively.

In this case, when the pattern code 1, the pattern code 2, and the pattern code 3 are combined in order, the pattern code 1, the pattern code 2, and the pattern code 3 are normally matched with the UUID 82, and in an abnormal case, the pattern code 1 is not identical. The combination of these pattern codes can be set by the administrator.

Specifically, as shown in FIG. 6C, the pattern code 1 of the QR code 1 is '1b5a2c97-38d', the pattern code 2 of the QR code 2 is '1-4592-9cdc-', and the pattern code 3 of the QR code 3 Is 'ba17fff7ffba'. Combining these pattern noses sequentially will result in '1b5a2c97-38d1-4592-9cdc-ba17fff7ffba', which is consistent with the UUID 82. As a result of the QR code reading, this QR code is determined to be a normal QR code.

As another example, assuming that two QR codes are formed on each page of the printout as shown in FIG. 6B, the two QR codes are named 'QR code 1' and 'QR code 2', respectively. The pattern code of the QR code information 80 in the (QR code 1 to QR code 2) may also be named 'pattern code 1' and 'pattern code 2', respectively.

At this time, when the pattern code 1 and the pattern code 2 are combined in order, the pattern code 1 and the pattern code 2 are normally matched with the UUID 82, and in abnormal cases, the pattern code 1 and the pattern code 2 are inconsistent with the UUID 82. FIG. The combination of these pattern codes can be set by the administrator.

Specifically, as shown in FIG. 6B, pattern code 1 of QR code 1 is '1b5a2c97-38d1-4592', and pattern code 2 of QR code 2 is '9cdc-ba17fff7ffba'. Combining these pattern noses sequentially will result in '1b5a2c97-38d1-4592-9cdc-ba17fff7ffba', which is consistent with the UUID 82. As a result of the QR code reading, this QR code is determined to be a normal QR code.

As described above, when the QR codes are four as shown in FIG. 6D, the digits of the pattern code 86 are 9 digits. When the QR codes are three as shown in FIG. 6C, the digits of the pattern code 86 are 12 digits. 6B, when the QR codes are two, the number of digits of the pattern code 86 is 18 digits. In addition, when there is one QR code as shown in Figure 6a it was configured such that the pattern code 86 does not exist.

Hereinafter, a description will be given of a method for outputting an output in which a QR code is inserted according to the present invention through embodiments.

Embodiment 1

7 is a flowchart showing a method of outputting an output (document or the like) in which a QR code is inserted according to Embodiment 1 of the present invention.

Referring to FIG. 7, the present invention uses a multifunction apparatus (image forming apparatus) 50 having a complex output function of a copy, scan or fax transmission function, and outputs (copy / scan / fax) an output in which a QR code is inserted. Transmission, etc.), and a method of outputting the output in which the QR code is inserted.

First, in the present invention, a user authentication step (S701) for authenticating a user through an authentication terminal provided in the multifunction apparatus (image forming apparatus) 50 is performed.

That is, the user is authenticated through the authentication terminal 40 provided in the multifunction apparatus (image forming apparatus) 50.

As an example, the RFID employee ID 1 is used. Specifically, when the employee ID 1 approaches the authentication terminal 40, the RFID reader 41 of the authentication terminal 40 reads user information from the RFID tag 1a in the employee ID 1, and this user information is authenticated. It is transmitted from the terminal 40 to the management server 30. Then, the management server 30 compares and determines the user information transmitted from the authentication terminal 40 and the user information stored in the third storage unit 35 of the management server 30, and as a result of the comparison, the two user information is the same The user then completes the authentication.

This authentication terminal can also be integrated with the multifunction apparatus (image forming apparatus) 50.

After performing the user authentication step (S701) as described above, the present invention performs the output request step (S702).

That is, by the user who performed the authentication, an output request (output instruction reception) for the output (document) in which the QR code is inserted is made in the multifunction apparatus (image forming apparatus) 50.

The output request of the output is made by pressing one of the buttons (copy / scan / fax transmission button) for performing output (copy / scan / fax transmission) of the output with the QR code inserted therein. .

After performing the output request step (S702) as described above, the present invention performs the cut file generation step (S703) (S704).

That is, in response to an output request (eg, a copy instruction, etc.) of the output in which the QR code is inserted by the user, the multifunction apparatus (image forming apparatus) 50 acquires (acquires) an image of the entire output in which the QR code is inserted. In operation S703, the entire output image file is generated (S703), and only the QR code region is cut from the obtained output entire image (crop) to generate a QR code cut image file (S704). The generated output image file and the QR code cut image file are stored in the storage (RAM) 52 or the external memory 63 inside the multifunction apparatus (image forming apparatus) 50.

After performing the cut file generation step (S703) (S704) as described above, the present invention performs the QR code cut image file transmission step (S705).

That is, the QR code cut image file generated in the cut file generation step (S703) (S704), the image forming apparatus login user information, and the information of the multifunction apparatus (image forming apparatus) 50 are combined with the multifunction apparatus (image forming apparatus) 50 ) Is transmitted to the relay server 20.

Information transmitted from the multifunction apparatus (image forming apparatus) 50 to the relay server 20 includes user information (user name, user ID, etc.), document information (document creator name, document page number, document name, document number, document title, etc.). Etc.), document printing information (paper size, color information, print request date, etc.), information of the multifunction apparatus (image forming apparatus) 50 as a sender (such as a multifunction apparatus (image forming apparatus) IP address), and the relay server 20 as a destination. ) Information (relay server IP address, etc.) may be included.

Such information may be stored in a memory unit in the relay server 20 or in an external storage (DB, Data Base, database) connected to the relay server 20 and displayed on a web page connected to the relay server 20.

After performing the QR code truncation image file transmission step (S705) as described above, the present invention performs a QR code reading step (S706).

That is, the relay server 20 stores the QR code cut image file, the image forming apparatus login user information, and the information of the multifunction apparatus (image forming apparatus) 50 from the multifunction apparatus (image forming apparatus) 50, and then stores the QR code. QR code information 80 is read (extracted, acquired) from the code cutout image.

The QR code information 80 includes a QR code generation time 81, a UUID 82, security information 83, an output limit number 84, a user name 85, a pattern code, and the like. Detailed descriptions thereof are made in the description of FIGS. 6A to 6E and thus will be omitted.

The read QR code information 80 is stored in the second storage 25 inside the relay server or in a repository DB 74 on the web associated with the relay server 20.

After performing the QR code reading step (S706) as described above, the present invention performs the step of determining whether the output possible (S707).

That is, the relay server 20 is capable of outputting the output (secure document) in which the QR code is inserted based on the QR code information 80 read (extracted) in the QR code reading step S706 (or outputting possible or Output impossible).

Specifically, whether to be able to output (enable or not) in the output possible determination step (S707) determines the security information 83 in the QR code information 80 read (extracted) in the QR code reading step (S706). Can be based

As an example, if the security information 83 in the QR code information 80 is marked as '0', the output possibility determination step (S707) determines that output is possible for the corresponding output, and the security in the QR code information 80 is determined. If the information 83 is marked as '1', it is determined in the step of determining whether the output is possible (S707) that the output of the corresponding output is impossible.

In addition, the determination of whether the output is possible or not possible in the output possibility determination step S707 is based on the security level information in the QR code information 80 read (extracted) in the QR code reading step S706. Can be.

As an example, if the security level information in the QR code information 80 is marked as less than a predetermined level (for example, 0 to 3 grades), it is determined that output is possible for the corresponding output, and the security level information in the QR code information 80 is If it is marked more than the predetermined grade (eg, grades 4 to 7), it is determined that the output is not possible.

The determined output availability (possibility or impossibility) information is stored in the second storage unit 25 in the relay server 20 or the repository DB 74 on the web associated with the relay server 20.

After the step of determining whether the output is possible as described above (S707), the present invention performs the determination result transmission step (S708).

That is, in addition to the QR code information 80 read in the QR code reading step (S706) and the output availability information determined in the output availability determination step (S707), the image forming apparatus information, the user information, and the like are relay servers 20. Is transmitted from the multifunction apparatus (image forming apparatus) 50 to.

After performing the determination result transmission step S708 as described above, the present invention performs a corresponding action according to the determination result.

That is, when it is determined in the output possible determination step (S707) that the output of the QR code is inserted (secure document) is determined that the output possible, the multifunction apparatus (image forming apparatus) 50, the output of the QR code is inserted Perform the output (S709a).

However, when it is determined in the output possibility determination step (S707) that the output of the QR code is inserted into the output (secure document) is determined as impossible, the multifunction apparatus (image forming apparatus) 50 outputs the output of the QR code is inserted. (S709b)

Then, in the present invention, the history information of the output is updated (S710).

Embodiment 2

In Embodiment 1, in response to a request for output of the output with the QR code inserted by the user, the multifunction apparatus (image forming apparatus) 50 performs image acquisition (acquisition) on the entire output with the QR code inserted therein, and the entire output. An image file was generated, and a QR code cut image file was generated by cutting only the QR code region from the obtained output image. The QR code information 80 was read (extracted) from the QR code cut image by the relay server 20. , Obtained). However, it is not limited to this.

That is, in Embodiment 2, in response to a request for output of the output into which the QR code is inserted by the user, the multifunction apparatus (image forming apparatus) 50 performs image acquisition (acquisition) on the entire output of the QR code. The entire output image file is generated, and then the relay server 20 reads (extracts and acquires) the QR code information 80 from the entire output image.

At this time, in the second embodiment, when reading (extracting, acquiring) the QR code information 80 from the entire output image, it may be relatively difficult to specify the position of the QR code image inserted in the output as compared to the first embodiment. It is possible to specify the position of the QR code image in the output based on the information of the output, for example, based on the size (standard) information of the output (document) and the position information of the QR code for each size of the output.

The information of this output is transmitted together when the entire image file of the output is transmitted from the multifunction apparatus (image forming apparatus) 50 to the relay server 20.

Embodiment 2 has the advantage that the procedure is relatively simplified since there is no need to perform the QR code truncation step, compared to Embodiment 1.

On the other hand, compared with Embodiment 2, Embodiment 1 has the advantage that the file capacity transmitted to the relay server 20 is drastically reduced, and system operation efficiency is improved. That is, in Embodiment 1, since only the QR code image cut out is transmitted from the multifunction apparatus (image forming apparatus) 50 to the relay server 20, the transmission speed is relatively higher than that in Embodiment 2, and the relay server 20 is also cut out. You can save the storage space by receiving and storing only the QR code image that has been received, and since you do not need to search and specify the location of the QR code even when acquiring (extracting) the QR code information 80 from the QR code cut image, The code information 80 acquisition time is also saved.

Embodiment 3

In determining whether the output is possible (possible or impossible) in the output possibility determination step of Embodiment 1, as an example, based on the security information 83 in the QR code information 80 read (extracted) in the QR code reading step. It was set as.

Specifically, in the output determination step of the first embodiment, if the security information 83 in the QR code information 80 is marked as '0', it is determined that the output is possible for the corresponding output, and the QR code information 80 If the security information 83 is marked with '1', it is determined that the output is impossible for the corresponding output. However, it is not limited to this. That is, in the output determination step of the second embodiment, if the security information 83 in the QR code information 80 is marked with '1', it is determined that the output is possible for the corresponding output, and the security in the QR code information 80 is determined. If the information 83 is marked as '0', it may be configured to determine that the output is impossible for the corresponding output.

In addition, when determining whether the output is possible (possible or impossible) in the output possibility determination step of Embodiment 1, as another example, the security level information in the QR code information 80 read (extracted) in the QR code reading step is used. Based on that.

Specifically, in the output determination step of the first embodiment, if the security level information in the QR code information 80 is less than a predetermined level (for example, 0 to 3 grades), it is determined that the output can be output for the corresponding output, and the QR If the security level information in the code information 80 is marked as a predetermined level or more (for example, 4 to 7 grades), it is determined that output of the corresponding output is impossible. However, it is not limited to this. That is, in the output determination step of the second embodiment, if the security level information in the QR code information 80 is less than a predetermined level (for example, 0 to 3 levels), it is determined that the output is impossible for the corresponding output, and the QR code If the security level information in the information 80 is expressed as a predetermined level or more (for example, 4 to 7 grades), it may be configured to determine that the output is possible for the corresponding output.

In Embodiment 1, as an example, when the security level information is 0 to 3 grades, it is determined that output is possible for the corresponding output, and when the security level information is 4 to 7 grades, it is determined that the output is not possible for the output. . Thus, in Embodiment 1, although it divided into grade 8 (grades 0-7), it can be variously modified. For example, by classifying into 15 grades, it is determined that the output can be outputted when the security level information is 1 to 7 grades, and that it is impossible to output the output when the security grade information is 8 to 15 grades. It can also be configured.

These settings are made in advance by the administrator.

Embodiment 4

Meanwhile, the present invention may further include a QR code verification step between the QR code reading step and the output availability determination step.

In the QR code verification step, the QR code reading result verifies whether the read QR code is normal (normal or abnormal).

Specifically, as illustrated in FIGS. 6B to 6D, a plurality of QR codes may be inserted into each page (page, page) of the output, and a plurality of QR codes may be inserted (eg, 2 to 4). Pattern codes 86 are formed for the purpose of distinguishing the QR codes.

Here, when the pattern codes of the QR code information 80 in the plurality of QR codes are combined, it is determined whether they match the UUID 82 of the QR code information 80 of the plurality of QR codes. If the 86 and the UUID 82 coincide with each other, the next step, that is, whether the output can be determined is performed.

If the combined pattern code 86 and the UUID 82 do not match, a check is made by notifying the administrator through SMS (Short Message Service) text or E-mail transmission method.

The verification result and the inspection result are applied to and added to the history information to update (update) the history information.

Embodiment 5

In Embodiment 1 of the present invention, the output limit number value is specified (set) in advance by an administrator. For example, when the output limit number value is set to '5' as the default value by the administrator, When the QR code is generated according to the QR code insertion and generation request, the 'output limit count value' of the QR code information 80 is automatically generated (recorded) as '5'. As described above, the output limit number value was applied to all users and departments in the same manner. But it is not limited to this.

That is, in Embodiment 5 of the present invention, the output limit number value for each user or for each department may be applied differently.

As an example, user 1 may set the output limit number of times to '5', user 2 may set the output limit number of times to '7', and user 3 may set the output limit number of times to '0'. In this case, user 3 also means that output of the corresponding output (document, etc.) is not possible.

In addition, department 1 sets the output limit number of times to '3', department 2 sets the output limit number of times to '6', and department 3 sets the output limit number of times to '0'. This also means that department 3 cannot print the output (documents, etc.).

If you want to limit the output of a specific document to the user (eg user 3) or department (eg department 3) as above, set the output limit count value among the QR code information 80 as '0 (zero)'. Just do it.

Embodiment 6

In the description of FIGS. 8 and 9, the security information value of the QR code information 80 is represented by a number '0' or '1', but is not limited thereto. That is, the security information value of the QR code information 80 may be represented by the letter 'A' or 'B', may be represented by the figure '○' or '●', and the letter '○' or 'X'. Can be indicated.

Embodiment 7

As a combination method of pattern codes (forward combination method of pattern codes) according to Embodiment 1 of the present invention, a method of combining pattern code 1, pattern code 2, pattern code 3, and pattern code 4 was used. But it is not limited to this.

That is, as a combination method of the pattern codes according to the seventh embodiment of the present invention, there may be a method of combining the pattern code 4, the pattern code 3, the pattern code 2 and the pattern code 1 (the reverse combination method of the pattern codes). .

Specifically, as described above, when the UUID 82 was '1b5a2c97-38d1-4592-9cdc-ba17fff7ffba', in FIG. 7E, the pattern code 1 of the QR code 1 is '1b5a2c97-' and the pattern of the QR code 2 Code 2 is '38d1-4592', pattern code 3 of QR code 3 is '-9cdc-ba1', and pattern code 4 of QR code 4 is set to '7fff7ffba'.

However, in reverse order of these pattern codes, pattern code 4 of QR code 4 is' 1b5a2c97- ', pattern code 3 of QR code 3 is' 38d1-4592', and pattern code 2 of QR code 2 is' -9cdc-ba1 ', and the pattern code 1 of the QR code 1 can be configured to be' 7fff7ffba '.

Combining these pattern noses in reverse order results in '1b5a2c97-38d1-4592-9cdc-ba17fff7ffba', which is consistent with UUID 82. As a result of the QR code reading, this QR code is determined to be a normal QR code.

In the above, the forward combining method of the pattern codes and the reverse combining method of the pattern codes are exemplified, but the present invention is not limited thereto. That is, there may be a method of combining the pattern code 3, the pattern code 2, the pattern code 1 and the pattern code 4, the method of combining the pattern code 2, the pattern code 4, the pattern code 1 and the pattern code 3.
