  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram illustrating a configuration of a print processing system 50 according to the first embodiment.

  The system 50 is connected to a plurality of client terminals 10 (10a, 10b, 10c,...) Used by a user for printing a document, and the client terminal 10 via a network 20, and the client terminal 10 connects to the user. And a print processing device 30 that receives print data generated and sent based on the print instruction and performs print processing of the print data.

  The client terminal 10 is composed of, for example, a PC (Personal Computer), and in addition to normal functions such as the control unit 11, the storage unit 12, the input unit 13, and the display unit 14, setting of authentication printing (secure print) unique to the present invention. A secure print setting control unit 15 that performs control is provided.

  The print processing apparatus 30 includes a control unit 31 that controls the entire apparatus 30, a storage unit 32 that stores various information, a touch panel having an input function and a display function, and the like. An input unit 33 that inputs various information, a client terminal Secure print control for executing the unique secure print control of the present invention in cooperation with the print unit 34 that prints an image on a recording medium based on the print data received from 10 and the secure print setting control unit 15 of the client terminal 10 A portion 35 is provided.

  In this system 50, regarding the secure print function, in the client terminal 10, the secure print setting control unit 15 is specified by the user from the input unit 13 in order to set secure print in response to a print instruction for document information (image data). Control (authentication setting information) is used to generate incomplete print data corresponding to the print instruction target image data and send it to the print processing apparatus 30. On the other hand, the print processing apparatus 30 performs secure print control. When the unit 35 receives incomplete print data from the client terminal 10, the print data is put on hold, and then specific information input from the input unit 33 by the user to execute secure printing. Use (authentication execution information) to restore (complement) the incomplete print data. There, it performs control to reject the print if 該補 complete could not restore the complete print data failed.

  The specific information (authentication setting information and authentication execution information) input at the client terminal 10 and the print processing apparatus 30 corresponds to, for example, image data that has been instructed for secure print setting at the time of print instruction at the client terminal 10. Information constituting part of the generated print data (for example, a file header portion) is used.

  Based on the operation outline of the secure print function described above, the configurations of the secure print setting control unit 15 of the client terminal 10 and the secure print control unit 35 of the print processing apparatus 30 will be described in more detail.

  In FIG. 1, the secure print setting control unit 15 of the client terminal 10 includes an input information determination unit 151 that determines that specific information input from the input unit 13 by the user is part of print data, and an input information determination unit. When it is determined by 151 that the specific information is part of the print data, the specific information is used to generate print data corresponding to the print instruction target image data and incomplete print data. Based on the print data generation instruction from the print data generation instruction unit 152 and the print data generation instruction unit 152 that respectively instruct a print data generation unit 153 and an incomplete print data generation unit 154, which will be described later, to determine and generate print data. , Print data generation unit 153 that generates print data corresponding to the print instruction document using the specific information, print data generation instruction Based on the print data generation instruction from 152, incomplete printing that generates incomplete print data by deleting a part of the information (for example, the specific information) from the print data generated by the print data generation unit 153 The data generation unit 154 includes a data transmission unit 155 that transmits the incomplete print data generated by the incomplete print data generation unit 154 to the print processing apparatus 30.

  Note that the input information determination unit indicates that the information input from the input unit 13 after the print instruction for the desired image data is not specific information (information constituting a part of the print data) instructing the secure print setting. If it is determined by 151 (including the case where the specific information is not input), the print data generation instruction from the print data generation instruction unit 152 is sent only to the print data generation unit 153, and normal print processing is performed. Is done.

  In this normal printing process, the print data generation unit 153 generates an image file (print data: complete print data) including the image data instructed to be printed, and sends the print data to the print processing apparatus 30.

  In FIG. 1, the secure print control unit 35 of the print processing apparatus 30 includes a print data determination unit 351 that determines whether the print data received from the client terminal 10 is incomplete print data, and a print data determination unit. In response to the incomplete print data determined in step 351, specific information instructing execution of secure printing is input from the input unit 33, and the specific information is used to supplement the incomplete print data. A print data restoration unit 352 that restores complete print data by performing the above-described process, and a print rejection control unit 353 that rejects printing when the print data restoration unit 352 fails to complement the print data and cannot restore the print data. Configured.

  Here, in order to facilitate understanding of the secure print control in the print processing system 50 of this embodiment, first, a normal print processing operation of the system 50 will be described.

  In this system 50, the client terminal 10 activates a predetermined application from the input unit 13 by the user and displays the editing screen on the display unit 14. Then, the client terminal 10 is input by the user from the input unit 13. The image data (document information) is edited according to the information to be edited and the editing operation.

  During editing of the image data, a user who wants to print the image data uses the input unit 13 to perform a print request operation (print instruction operation).

  Here, since normal print processing is assumed, specific information for setting secure print corresponding to the print request target image data is not input in the print instruction.

  When the print instruction is given, the client terminal 10 generates print data (image file) including the image data instructed to be printed by the print data generation unit 153, and the print data is transmitted through the data transmission unit 155 to the print processing apparatus. 30.

  When the print processing apparatus 30 receives the print data from the client terminal 10, the print data determination unit 351 determines that the received data is complete print data. Based on the determination result, the control unit 31 transfers the print data to the printing unit 34, and the printing unit 34 prints and outputs an image on a recording medium based on the print data.

  FIG. 2 is a diagram showing the format of print data (image file) 17 that is generated based on a print instruction from the input unit 13 at the client terminal 10 and sent to the print processing apparatus 30 in the normal print processing.

  As shown in FIG. 2, the print data 17 includes a file header portion 171, an information header portion 172, a color palette portion 173, and an image data portion 174.

  The file header portion 171 is information of a fixed length (for example, 10 bytes), format information indicating the format of the file (2 bytes: for example, 0x8888 for the non-secure print method, 0x0000 for the secure print method), It consists of size information (4 bytes) indicating the overall size of the file and offset information (4 bytes) of image data mounted on the file.

  The information header part 172 is variable-length information. The information header size information (4 bytes), image horizontal size information (4 bytes), image vertical size information (4 bytes), and the number of color palettes are displayed. Information (2 bytes), information indicating the presence or absence of compression (2 bytes), horizontal resolution information (4 bytes), and vertical resolution information (4 bytes). Note that the compression presence / absence information and the resolution information in the horizontal direction and the vertical direction exist as many as the number of colors indicated by the information indicating the number of color palettes.

  The color palette unit 173 includes the luminance information of each color described above.

  The image data unit 174 is an information area for storing image data instructed to be printed. The image data portion 174 is mounted with the expression content of image data for one line from left to right and lines from top to bottom. Here, the size of one line is a multiple of 32 bits for the convenience of processing, and if not enough, 0 is inserted and adjusted.

  When the print data generation unit 153 of the client terminal 10 generates the print data 17 having the format shown in FIG. 2, first, the print data generation unit 153 generates a file header based on the image data instructed by the input unit 13. Specifically, information necessary for constructing the header is extracted by analyzing the image data, and a file header is generated based on the extracted information.

  Next, the print data generation unit 153 merges the file header and the image data into one print data 17 (the file header and the image data are put in the file header unit 171 and the image data unit 174, respectively, and further the information header And the print data 17 are sent to the print processing apparatus 30.

  As a specific example of the file header 171, when the user selects the A method (method determined as an example of non-secure printing for convenience) and generates the print data 17, for example, 0x8888 is stored in the format information of the file header portion 171.

  On the other hand, when the print processing apparatus 30 receives the print data 17 from the client terminal 10, it reads the information in the file header portion 171 of the print data 17 and prints an image according to the analysis result.

  That is, if the format information of the file header portion 171 is 0x8888, the image data can be developed through processing according to the file format recognized from the 0x8888, and a correct print result can be obtained.

  At this time, if it is assumed that the file format is unknown (including the file header but the format itself cannot be analyzed) when the print data 17 received by the print processing device 30 is printed, the file header in this case Since the information of the part 171 cannot be analyzed, the image cannot be printed.

  For example, if the format information of the file header portion 171 is not 0x8888 which can recognize the file format but 0x0000, it is unclear how the image data can be developed, and the image cannot be printed. Become.

  Note that the case where the file format is unknown includes the case where the file header is included but the format itself cannot be analyzed as described above. The latter case is not assumed.

  In the present invention, secure print control is realized by paying attention to the above-described file header generation processing of the print data 17 in the client terminal 10 and image data expansion processing based on the file header information in the received data in the print processing device 30. It is.

  That is, in the print processing system 50 according to this embodiment, when specific information for setting secure printing is input when the client terminal 10 issues a print instruction for image data, the print instruction is used using the input information. Print data corresponding to the target image data is generated, and incomplete print data in which a part of the information (for example, format information in the file header portion) is lost is generated from the print data, and the print processing apparatus 30 is informed. On the other hand, when the print processing apparatus 30 receives incomplete print data from the client terminal 10, the print processing apparatus 30 waits for input of specific information instructing execution of secure print in a state where the print is put on hold, and then inputs the information. Using the specified information, the process for complementing the incomplete print data is performed. When the completion of the missing information in the data (for example, the format information of the file header portion) is successful and the complete print data can be restored, the complete print data is printed and the above complement is performed. If the print data fails and complete print data cannot be restored, control is performed to reject printing.

  Considering the example given above, after the print instruction, the client terminal 10 receives print data 17 (see FIG. 2) composed of the image data instructed for printing and the file header portion generated by the analysis result of the image data. At the time of creation, after generating print data storing original 0x8888 as the format information of the file header part, when secure print control is selected, incomplete print data in which the information of 0x8888 is deleted is generated, This incomplete print data is sent to the print processing apparatus 30.

  At this time, the format information in the file header portion of the incomplete print data stores information of 0x0000, which means the lack of information of 0x8888 described above.

  On the other hand, the print processing apparatus 30 that has received the incomplete print data from the client terminal 10 tries to analyze the format information of the file header portion of the print data and develop the image data. Since the format information is not the original 0x8888 but 0x0000, which means missing information, the file format is unknown, and as it is, the method of developing the image data is unknown and the image cannot be printed.

  In this case, in order to print an image based on the received print data, the user inputs the format information (0x8888) of the original file header from the input unit 33 in the print processing apparatus 30.

  If the print processing apparatus 30 is configured so that when the original format information (0x8888) is input, the input information is regarded as the format information of the file header portion, the original format information (0x8888) Even if the information in the file header is missing (when information = 0x0000), the image data is expanded based on the analysis result of the original format information (0x8888), and the image Data can be printed.

  Next, the print processing operation in the print processing system 50 of this embodiment will be described with reference to FIGS.

  3 is a flowchart showing a secure print setting operation in the client terminal 10, and FIG. 4 is a flowchart showing a secure print control operation in the print processing apparatus 30.

  First, the processing operation of the client terminal 10 will be described with reference to FIG.

  In FIG. 3, when there is an image data print instruction from the input unit 13 (step S <b> 301), the control unit 11 of the client terminal 10 continues to determine whether or not specific information is input from the input unit 13. 151 is determined (step S302).

  Here, the input information determination unit 151 has a functional configuration for recognizing that specific information input from the input unit 13 is a part of print data, and the information input in step 302 is the print data. If it is recognized that it is a part of the information, it is determined that specific information is input.

  When the input information determination unit 151 determines that specific information has been input (YES in step S302), the print data generation instruction unit 152 then determines the determination result of the input information determination unit 151 (the specification input in step S302). Based on the determination result that the information is part of the print data), it is determined that the print data corresponding to the print instruction target image data and the incomplete print data are generated using the specific information. The print data generation unit 153 and the incomplete print data generation unit 154 are each instructed to generate the print data.

  Based on the print data generation instruction from the print data generation instruction unit 152, first, the print data generation unit 153 generates print data corresponding to the print instruction target image data using the specific information input in step S302. (Step S303).

  The print data generated here has, for example, a format as shown in FIG. 2, and the specific information input in step S302 is embedded in a part of the file header portion.

  Next, the incomplete print data generation unit 154 is embedded in a part of the print data generated by the print data generation unit 153 based on the print data generation instruction, for example, in the file header portion of the print data. Incomplete print data is generated by deleting the specific information (input in step S302) (step S304).

  Thereafter, the control unit 11 causes the data transmission unit 155 to send the incomplete print data generated by the incomplete print data generation unit 153 to the print processing apparatus 30 (step S305).

  When it is determined in step S302 that specific information has not been input (NO in step S302), the control unit 11 controls normal printing processing (step S310).

  In this normal printing process, print data corresponding to the image data instructed for printing in step S301 is generated by the print data generation unit 153, and the print data is sent from the data transmission unit 155 to the print processing apparatus 30.

  Next, the processing operation of the print processing apparatus 30 will be described with reference to FIG.

  In FIG. 4, the print processing apparatus 30 print data sent from the client terminal 10 through the processing operation shown in FIG. 3 (print data sent via step S310, or incomplete print sent via step S304). Data) is received (step S401), and the received print data is input to the print data determination unit 351.

  The print data determination unit 351 refers to, for example, information in the file header portion of the input print data, and determines whether the print data is incomplete depending on whether or not a part of the information is missing. It is determined whether or not (step S402).

  If it is determined that there is no missing information in the file header part and the print data is complete (NO in step S402), the control unit 31 transfers the print data to the print unit 34, and the print data is transferred to the print unit. A normal printing process (step S410) for printing out at 34 is performed.

  On the other hand, when the information in the file header portion of the received print data is missing and the incomplete print data determination unit 351 determines whether the print data is incomplete print data (YES in step S402). ), The control unit 31 sets the secure print mode (step S403).

  When this secure print mode is set, printing for incomplete print data is put on hold and a state of waiting for input of specific information for releasing the hold, that is, for instructing execution of secure print is maintained. .

  As an input waiting state for specific information for the secure print execution instruction, the control unit 31 displays, for example, incomplete print data pending printing on the information display function unit of the input unit 33 configured by a touch panel. Displays an input waiting screen that prompts the user to input corresponding specific information.

  After setting the secure print mode, the control unit 31 monitors whether or not specific information is input from the input unit 33 using the input waiting screen (step S404).

  Here, when specific information is input (YES in step S404), the print data restoring unit 352 performs processing for complementing corresponding incomplete print data using the input specific information (step S405). ).

  As a specific process, the print data restoration unit 352 embeds the specific information input in step S404 in the information missing part of the file header part of incomplete print data, and complete printing with a normal file header part. Perform processing to restore the data.

  In this complementing process, when the specific information input in step S404 is embedded in the information missing part of the file header part of incomplete print data to form a normal file header part, and the complementing process is successful (step In step S407, the control unit 31 transfers the complete print data that has been successfully complemented to the printing unit 34 to be printed out (step S407).

  Next, the secure print mode set in step S403 is canceled (step S408), and thereafter, preparation for reception of the next print data is performed.

  On the other hand, in the complementing process in step S405, even if the specific information input in step S404 is embedded in the information missing part of the file header part of incomplete print data, it can be formed as a normal file header part. If the complement processing fails (NO in step S406), the print rejection control unit 353 performs control to reject printing (step S420), and then returns to step S404.

  Next, a secure print processing image in the print processing system 50 according to the first embodiment will be described in more detail with reference to FIGS.

  FIG. 5 is a conceptual diagram showing a secure print setting process image in the client terminal 10 of the present embodiment, and FIG. 6 is a conceptual diagram showing a secure print execution process image in the print processing apparatus 30 of the present embodiment.

  In FIGS. 5 and 6, the parentheses indicate the step names of the corresponding processes in FIGS. 3 and 4, respectively.

  As shown in FIG. 5, in the client terminal 10 according to this embodiment, when the user performs secure print setting corresponding to the image data for which a print instruction (corresponding to step S301 in FIG. 3) is made, Specific information (in this example, 0x8888) is input (corresponding to YES in step S302).

  Thereafter, the print data generation unit 153 generates print data in which the specific information input from the input unit 13 is embedded in the file header (corresponding to step S303).

  Further, the incomplete print data generation unit 154 generates incomplete print data in which specific information input from the input unit 13 is missing from the file header portion of the print data generated by the print data generation unit 153. (Corresponding to step S304), this incomplete print data (changed to 0x0000 which means that the missing part of the file header part is missing) is sent from the data sending part 155 to the print processing apparatus 30 (same as above). Corresponding to step S305).

  On the other hand, as shown in FIG. 6, the print processing apparatus 30 according to this embodiment receives the incomplete print data sent from the client terminal 10 and converts the incomplete print data into an incomplete print data determination unit. If the determination is made at 351, the secure print mode is set, printing is put on hold, and the input of specific information is awaited (corresponding to step S403 in FIG. 4).

  In this state, when specific information (in this example, 0x8888) corresponding to the incomplete print data is input by the user (print instructor at the client terminal 10) using the input unit 33, the print data is restored. The unit 352 performs processing for complementing the file header portion of incomplete print data using the input specific information (corresponding to step S405).

  Here, when the specific information input from the input unit 33 has the same value as the specific information input at the time of secure print setting in the client terminal 10, the specific information input from the input unit 33 is used in the above complement processing. The file header portion of the incomplete print data is complemented by the information of the above, and the complete print data is restored (corresponding to step S406 YES).

  The complete print data that has been successfully complemented is then sent to the printing unit 34 for printing. At this time, a normal print result (corresponding to step S407) is obtained based on the complete print data.

  On the other hand, when the specific information input from the input unit 33 is different from the specific information input at the time of secure print setting in the client terminal 10 (route indicated by a dotted arrow in FIG. 6). In the above complement processing, the file header portion of incomplete print data cannot be complemented by the specific information input from the input unit 33, and complete print data cannot be restored (corresponding to step S406 NO).

  As described above, when the incomplete print data supplement fails and the complete print data cannot be restored, the print rejection control unit 353 controls to reject the printing at this time (corresponding to step S420). .

  Note that when the above complement processing fails, the incomplete print data held in the print processing device 30 lacks the information in the file header portion. The print result cannot be obtained.

  That is, even if this incomplete print data is captured by a person other than the print instructor who issued the print instruction, the captured data cannot be used.

  In the first embodiment, specific information (authentication setting information and authentication execution information) input by the user is used as it is, and incomplete print data generation processing and incomplete print data supplement processing are performed. Then, specific information input by the user is converted by a predetermined conversion method, and incomplete print data generation processing and incomplete print data supplement processing are performed using the converted information (conversion generation information).

  The basic functional configuration of the print processing system according to the second embodiment (referred to as 50B for the sake of convenience) is the same as that of the print processing system 50 according to the first embodiment shown in FIG. The operation will be described.

  FIG. 7 is a flowchart showing a secure print setting process operation in the client terminal 10 of the print processing system 50B according to the second embodiment. FIG. 8 is a flowchart showing a secure print control operation in the print processing apparatus 30 of the system 50B.

  As shown in FIG. 7, in the client terminal 10 according to the second embodiment, out of a series of processes (see FIG. 3) performed by the client terminal 10 according to the first embodiment, the process of steps S303a and 303b is changed to step S303. In addition, the process of step S304a is performed instead of the process of step S304, and the other processes are the same as those in the first embodiment.

  That is, in the client terminal 10 according to the second embodiment, when specific information is input from the input unit 13 when setting secure printing (YES in step S302), the input information is converted by a predetermined conversion method to generate a conversion. Information is generated (step S303a), and then print data in which the conversion generation information and the input information are embedded in the file header portion is generated (step S303b).

  Next, incomplete print data is generated by deleting the input specific information from the file header portion of the print data (step S304a).

  Further, in the print processing apparatus 30 according to the second embodiment, as shown in FIG. 8, in a series of processes (see FIG. 4) performed by the print processing apparatus 30 according to the first embodiment, in place of step S <b> 406, step S <b> 406 a is performed. And s406b, and the other processes are the same as those in the first embodiment.

  That is, in the print processing apparatus 30 according to the second embodiment, when specific information is input from the input unit 33 to instruct execution of secure printing (YES in step S404), the print data restoration unit 352 causes the input information Is used to complement the file header portion of the incomplete print data (step S405), and it is determined whether or not the complement has succeeded during the complement processing (steps S406a and S406b).

  In this case, first, the specific information input in step S404 is converted by the same conversion method as the specific information input at the time of secure print setting in the client terminal 10 to generate conversion generation information. Then, after this conversion generation information and the specific information input in step S404 are combined, the combined information is the information of the header part after complementation in step S405 (input in step S404) It is checked whether or not it matches with the result of complementing the file header part using specific information (step S406a), and if it matches, it is determined that the complementing is successful (YES in step S406b). If they do not match, it is determined that the complement has failed (step S406bNO).

  When it is determined that the complement processing is successful because the combined information and the information in the file header portion after the complement in step S405 match in the complement completion determination process (YES in step S406b), the control unit 31 Then, the complete print data that has been successfully complemented is transferred to the printing unit 34 and printed out (step S407).

  On the other hand, when it is determined in the above completion / non-completion determination process that the combined process and the information in the file header part after completion in step S405 do not match, the completion process has failed (step S406bNO). The print rejection control unit 353 performs control for rejecting printing (step S420), and thereafter, the processing after step S404 is continued.

  Next, a secure print processing image in the print processing system 50B according to the second embodiment will be described in more detail with reference to FIGS.

  FIG. 9 is a conceptual diagram showing a secure print setting process image in the client terminal 10 of this embodiment, and FIG. 10 is a conceptual diagram showing a secure print execution process image in the print processing apparatus 30 of this embodiment.

  In FIG. 9 and FIG. 10, the parentheses indicate the step names of the corresponding processes in FIG. 7 and FIG.

  As illustrated in FIG. 9, in the client terminal 10 according to the second embodiment, when the user performs secure print setting corresponding to the image data instructed to print (corresponding to step S <b> 301 in FIG. 7), from the input unit 13. Specific information (in this example, 1234) is input (corresponding to YES in step S302).

  Thereafter, the print data generation unit 153 converts the specific information input from the input unit 13 by a predetermined conversion method to generate conversion generation information (55.6731 in this example) (step S303a). Next, print data is generated by embedding the conversion generation information and the specific information input from the input unit 13 in the file header (corresponding to step S303b).

  Subsequently, the incomplete print data generation unit 154 generates the input information (in this example, 1234) from which the conversion generation information is generated from the file header portion of the print data generated by the print data generation unit 153. The missing incomplete print data is generated (corresponding to step S304a), and the incomplete print data is sent to the print processing apparatus 30 through the data sending unit 155 (corresponding to step S305).

  On the other hand, as shown in FIG. 10, the print processing apparatus 30 according to the present embodiment receives the incomplete print data sent from the client terminal 10 and uses the incomplete print data as an incomplete print data determination unit. If the determination is made at 351, the secure print mode is set, the printing is suspended, and the input of specific information is awaited (corresponding to step S403 in FIG. 8).

  In this state, specific information (in this example, 1234) corresponding to the incomplete print data is input by the user (print instructor at the client terminal 10) using the input unit 33 (step 404 YES). The print data restoration unit 352 performs processing for complementing the file header portion of incomplete print data using the input specific information (corresponding to step S405).

  In this complementing process, the print data restoration unit 352 converts the specific information input from the input unit 33 into the same conversion method as the conversion of the specific information input during secure print setting in the client terminal 10. To generate conversion generation information (in this example, 55.6731...) (Corresponding to step S406a), and information obtained by combining the conversion generation information and the input specific information is Whether the completion is successful or unsuccessful depending on whether or not it matches the information in the file header part after completion in step S405 (the result of complementing the file header part using specific information input from the input part 33). Judgment (corresponding to step S406b).

  Here, when the above-mentioned two pieces of information coincide with each other and complementation is successful (corresponding to YES in step S406b), complete print data that has been successfully complemented is sent to the printing unit 34 and printed out. At this time, a normal print result (corresponding to step S407) is obtained based on the complete print data.

  On the other hand, when the specific information input from the input unit 33 is a value different from the specific information input at the time of secure print setting in the client terminal 10 (path indicated by a dotted arrow in FIG. 10). The information generated by converting the specific information (in this example, ≠ 1234) and the conversion information (in this example, ≠ 55.6731...) And the specific information is the result of complementation in step S405. It does not match the information in the file header (the result of complementing the file header using specific information input from the input unit 33), and complete print data cannot be restored.

  As described above, the combination information of the input specific information and the conversion generation information obtained by converting the specific information does not match the information in the file header part after the completion using the specific information, and the completion fails (same as above). In the case of (corresponding to step S06b), the print rejection control unit 353 controls to reject the printing at this time (corresponding to step S420).

  In the above-described secure print control operation (see FIGS. 9 and 10), as a conversion method when the client terminal 10 and the print processing device 30 generate the conversion generation signal, for example, there is a method using a Sin function.

  For example, in the example of FIG. 9, when “1234” is input as specific information from the input unit 33 to the client terminal 10, the input information determination unit 151 sets the number “1234” (the print data is configured). Based on the determination result, the print data generation instruction unit 152 instructs the print data generation unit 153 and the incomplete print data generation unit 154 to generate print data.

  Based on the print instruction, the print data generation unit 153 maps the numerical value “1234” input as the specific information to, for example, a number from 0 to 127.

  At that time, the numerical value “1234” is converted into a modulo of the period of the Sin function by using the Sin function. In the case of this example, the modulo of the period 2π is taken and becomes “154”.

  Next, when 127 * Sin (154) is calculated in order to map “154” to a numerical value from 0 to 127, “55.67313564...” Is obtained.

  Next, print data is generated by combining the numerical value “1234” and the numerical value “55.67313564...” With the image data.

  Since the Sin function is a periodic function having a period of 2π, the numerical value input by the user can be selected infinitely. Further, since the Sin function is a continuous function, if the number of significant digits is increased, the value of Sin (x) can be selected infinitely, and the accuracy of the map can be arbitrarily selected.

  Next, the incomplete print data generation unit 154 deletes the numerical value “1234” from the print data, generates incomplete print data, and sends this to the print processing apparatus 30.

  On the other hand, as shown in FIG. 10, the print processing apparatus 30 determines that the print data received from the client terminal 10 is incomplete print by the incomplete print data determination unit 351 (file header of the print data). If it is determined that a part of information is missing), printing is suspended and input of specific information is awaited.

  Here, when a numerical value “1234” is input as the specific information from the input unit 33, the print data restoration unit 352 uses the input numerical value “1234” to complement incomplete print data. (The input numerical value is combined with the print data), and if complete, the complete print data is printed.

  Here, if information other than “1234” is input and the print data cannot be complemented based on the input information, the process again waits for input of specific information.

  Note that, in the above complement processing, whether or not incomplete print data can be complemented is determined by the same number map processing as this performed on the client terminal 10 side with respect to the specific information input from the input unit 33 (this In the example, the Sin function is used), and whether or not the mapped numerical values match is determined.

  As described above, as described with reference to the embodiments, in the secure print control of the present invention, when specific information (authentication setting information) for setting secure print is input, the client terminal 10 receives this specific information. Is used to generate incomplete print data corresponding to the print instruction document information (image data) and send it to the print processing device 30, while the print processing device 30 receives the incomplete print data received from the client terminal 10. When specific information (authentication execution information) instructing the execution of secure printing is input in response to this, the specified information is used to restore complete print data from incomplete print data. When complete print data cannot be restored, printing is rejected.

  According to this configuration, after inputting specific information at the client terminal 10 to set secure printing and instructing printing of document information, the print processing apparatus 30 inputs the specific information, and the specific information The normal print result of the print data can be obtained only when the complete data can be restored from the incomplete print data using.

  That is, in the present invention, the print data held in the print processing apparatus 30 is incomplete print data, and a normal print output result cannot be obtained even if this incomplete print data is printed as it is.

  In the present invention, even if the print data held in the print processing device 30 is captured, it cannot be used, and it is meaningless to capture print data by a person other than the print instructor. Become.

  In the present invention, the print data corresponding to the document information to be printed as specific information for setting secure print at the client terminal 10 and specific information for instructing execution of secure print by the print processing apparatus 30 Therefore, the confidentiality of each piece of information as authentication information is further increased.

  For the reasons described above, in the present invention, only the print instructor who has issued a print instruction at the client terminal 10 can print out the print data from which the print instruction has been issued on the print processing apparatus 30 side. Functions can be greatly enhanced.

  In addition, the present invention is not limited to the embodiment described above and shown in the drawings, and can be implemented by being appropriately modified within a range not changing the gist thereof.

  For example, in each of the above embodiments, the print processing apparatus 30 inputs information (authentication execution information) having the same value as the specific information (authentication setting information) input to set secure printing on the client terminal 10 side. The secure print is activated, but the client terminal 10 can generate incomplete print data in which a part of the print data corresponding to the image data instructed to be printed is deleted. On the other hand, as long as the incomplete print data received from the client terminal 10 can be combined and supplemented with the missing part, the authentication setting information and the authentication execution information need not be the same. Absent.

  Also, the information conversion method according to the second embodiment is not limited to the Sin function, and various conversion methods can be applied.

  The present invention can be applied to all print processing systems in which authentication printing is set for document information at a client terminal, and print data corresponding to the document information is printed out after execution of authentication by a print processing apparatus. The incomplete print data corresponding to the corresponding document information is sent to the print processing apparatus at the time of the authentication print setting, and the print processing apparatus does not input the information unless information that can restore the incomplete print data to the complete print data is input. By continuing to hold incomplete print data, a normal print result cannot be obtained from the incomplete print data, and the security function can be strengthened.
