Abstract:
When transferred data is registered, it is determined whether access to the registered data is or is not protected by a password. If it is determined that a password is necessary, an inquiry is made to the registration request side, as to whether or not registration processing is to be continued. If a response of agreeing to the registration is received, registration processing is continued, while if a response of not agreeing to the registration is received, the registration processing is stopped. When a request of outputting registered data is received, it is determined whether or not password is necessary to output the registered data. If it is determined that password is necessary, password input is requested to an output request side. If a password inputted by the output request side is correct output processing is continued, while if the password is not correct, the output processing is stopped.

Description:
FIELD OF THE INVENTION 
   The present invention relates to information processing method, and system and apparatus thereof capable of temporarily storing data and reading necessary data by designating the data in accordance with necessity. More particularly, the present invention relates to processing of data with password for security. 
   BACKGROUND OF THE INVENTION 
   Conventionally known is a print system in which a document is uploaded from a client computer to a print server via the Internet and the document uploaded in the print server is print-outputted.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Hereinbelow, an image data print system as a preferred embodiment of the present invention will be described in detail in accordance with the accompanying drawings. Note that in the present embodiment, the present invention will be described as a print system, however, the present invention is not limited to the print system. The invention is a technique for registration of data in a server and reading the registered data, therefore it is applicable to other systems, and the other systems are included in the invention. 
   &lt;Configuration of Print System&gt; 
   (Print System) 
     FIG. 1  illustrates the outline of a print system to print-output image data according to the present embodiment. 
   The print system is constructed with various terminals  1  (host computer or client computer) installed in houses and/or offices, which generate image data, a PSTN or ISDN public line  2 , an Internet provider  3 , and a printer group  4  ( 4   a,    4   b  . . . ) including a server (print server) and plural printers provided in convenience stores and/or print shops. 
   Print subject data (hereinbelow, referred to as “image data”. For example, the image data is a PDF file.) is sent through the public line  2  and via the Internet provider  3  and is stored in a server  11  ( 11   a,    11   b  . . . ) in the printer group  4 . A user calls data from the server  11 , and obtains an output by a desired printer such as the printer  12   a  or  13   a  in the convenience store  12  or  13 . 
   Each terminal  1  performs editing, combining and the like on an image file which has been generated by a personal computer  8  or read by a digital camera  10  or scanner  7 , on the personal computer  8 . The terminal  1  can transmit the image file, as a print job, onto the public line  2 . Note that image data from the digital camera  10  or the scanner  7  may be transferred to the personal computer  8  via a mobile terminal  9  such as a PHS. Further, image data may be transmitted from a portable notebook personal computer as the personal computer  8  via such mobile terminal. 
   (Digital Multifunction Machine) 
   The printer used in convenience stores and/or print shops is a digital multifunction machine as shown in  FIG. 2 . 
   The digital multifunction machine has respective functions of copier, printer and facsimile (hereinbelow “FAX”) machines.  FIG. 2  shows a cross-sectional view of the digital multifunction machine including a print engine  21  for monochrome printing and its accessories. When an original is set in face-up state on a document feeder (DF)  22  and a start key is depressed, the original is conveyed to an upper surface of an original reader  23 . The original is irradiated with light from a light source  24 , then the reflected light is read by a CCD  25  and converted to a digital signal. The signal is subjected to desired image processing and converted to a laser print signal. 
   The print signal is converted to print laser by a laser printing unit  26 , then emitted to a photosensitive member  27 , to form a latent image on the photosensitive member  27 . Then toner development is performed, and the toner is transferred to a transfer sheet supplied from a paper cassette  28 . The toner is fixed to the paper by a fixing unit  29 , and discharged to a finisher  30 . 
   The finisher  30  performs various operations in correspondence with a function designated by an operator. More particularly, the finisher  30  has a staple (1 position and two position) function, a punch (2 holes and 3 holes) function, and a binding (saddle-stitch binding and the like) function. Two paper discharge trays  31  can be selectively used for the respective copier, printer and FAX functions by the operator&#39;s setting. A print engine  1 , which is for a monochrome printer here, may be a color printer engine. When the digital multifunction machine is used as a printer, the following functions may be set by a driver. For example, setting for monochrome/color printing, paper size, Nin1, double-sided, staple, punch, book binding, inserting paper, front cover, and back cover, can be made. 
   (Server) 
     FIG. 3  is a block diagram showing an example of the printer group  4  including the server  11  in  FIG. 1 . 
   The server  11  has a CPU  15 , a RAM  16 , a ROM  17 , a hard disk  19 , and a network interface (IF)  18 . The server  11 , which is an image server, also functions as a print server, and monitors the printers  12   a  and  13   a  respectively provided in the convenience stores  12  and  13 . That is, the server  11  monitors information on printer functions and specification and statuses such as current printer use status, job status, and printer available/unavailable status. 
   When the power of the server  11  is turned ON, the server  11  inquires about various printer information managed by the server as a print server, as “Power ON-Time Inquiry Information  61 ” in  FIG. 6 , at the printers. Then information obtained from the printers  12   a  and  13   a  are stored via the network IF  18  into the RAM  16 . When the powers of the printers are turned ON, the “Power-ON-Time Inquiry Information  61 ” is also obtained from the printers  12   a  and  13   a.    
   Thereafter, the server  11  obtains the printer status information as shown in the “Power-ON-Time Inquiry Information  61 ” in  FIG. 6  and stores the information into the RAM  16  by a predetermined (variable) period. The information acquisition may be made as polling from the server by predetermined time or transmission of status from the printers to the server by predetermined time. 
   The hard disk (HD)  19  of the server  11  holds various software to function as a print server and an image server. Further, the hard disk  19  holds information necessary for the print system. Next, a particular example of the stored data will be described. 
   In  FIG. 3 , in detailed user information  19   a,  the user&#39;s personal information such as address, telephone number, age, sex, and account number, is stored with a user ID. 
   In an image memory  19   b,  image data registered by users, image IDs and user IDs, respectively linked with each other, are registered. 
   As shown in  FIG. 7 , in job records  19   c,  the user IDs, the image IDs, and job IDs, respectively linked with each other, are registered. Further, the detailed content of job as shown in  FIG. 9  is also linked with the job ID and stored as a job record. 
   A promotion image file  19   d  includes image data to be printed in blank space of print sheet. The data is used for reduction from a charge amount paid by a user at a print shop in accordance with the size of blank space and the number of print sheets. 
   An accounting table  19   e  holds a charge table based on paper size, color/monochrome printing, paper type, and function (staple, punch and the like). The charge of a job requested by a user is calculated in accordance with the table. 
   In user accounting information  19   f,  the user IDs and accounting information such as printers, payment amounts, and output dates are respectively linked with each other and stored. The data is used for calculation of monthly accounting by user, and also used for monthly sales accounting by printer. 
   &lt;Operation Procedure of Print System&gt; 
   Hereinbelow, an example of the operation in the print system having the above configuration will be described. 
   (Conception of Operation) 
     FIG. 5  is a timing chart showing the conception of operation procedure for transmission of image data inputted from the terminal  1  by a user to the printer via the server (image server)  11 .
     (i) The image server  11  inquires about the information and statuses as shown in  FIG. 6  on the printer side.   (ii) The result of inquiry in (i) is returned from the printer to the image server  11 . The image server  11  obtains the information such as functions, specifications and statuses of the plural printers managed by the server as a printer server (see  FIG. 6 ).   (iii) The user edits image data inputted from the scanner and/or digital camera, and/or generated on the personal computer, then transmits the image data to the image server  11  to register the image data there. When the image data is registered in the image server  11 , image IDs are set for the respective registered images. The image server  11  side manages the image IDs and image data respectively linked with each other (see the image memory  19   b  in  FIG. 3 ).   (iv) When the image data has been registered, the image server  11  transmits a job setting screen for the registered images to the user terminal  1 . For example, a setting screen as shown in  FIG. 8  is transmitted. The user performs job setting in accordance with the setting screen. In the setting screen, the image ID is inputted. The user makes selections utilizing the setting screen for a function to be used.   (v) When the job setting using the job setting screen has been completed, the user sends the set job information to the image server  11  by clicking a transmission button.   (vi) The image server  11  receives the job in (v), then calculates a charge amount for the job and sends the result of calculation to the user terminal. For example, information checked on the user&#39;s personal computer is as shown in  FIG. 9 .   (vii) In consideration of the charge amount, the user gives approval of the job by depressing a print “OK” button in  FIG. 9 , and the result of selection is transmitted to the image server  11 .   (viii) The image server  11  returns data, indicating that the job from the user has been received, as a job ticket. The job ticket includes the user ID, a job ID and a document ID.   (ix) If the once-received job is to be changed, the transmission data used in  FIG. 9  is again used thereby the job can be changed. In  FIG. 9 , a job change “Yes” button is clicked and the data is transmitted to the image server  11 . Then the image server  11  sends the setting screen as shown in  FIG. 8  again. The user changes the job setting and transmits it.   (x) The image server  11  transmits the result of changed job setting and charge amount, similar to that shown in  FIG. 9 , to the user terminal.   (xi) The operation is the same as (vii)   (xii) The operation is the same as (viii)   (xiii) On the due date of printing, the image server  11  transmits the job ticket to the printer in preparation for printing. On the printer side, when the user inputs user authentication information such as the job ID and a password into the printer, printing becomes possible. The print output time is determined in accordance with determination of payment. That is, upon determination of payment by using a coin vendor, charging to the user&#39;s credit card, charging to a particular bank account, payment by electronic money, or the like, printing is started.   (xiv) When the printing has been completed, the printer sends information indicating the completion of printing to the image server  11 .
 
(Flowchart in Image Server)
   
     FIGS. 4A and 4B  are flowcharts showing a procedure of processing upon power-ON of the image server  11 , job reception and printing. 
   When the power of the image server  11  is turned ON (step S 1 ), the server obtains the statuses and specification information from the printer, and writes the data into the RAM in the image server (step S 2 ). The server always monitors whether or not the printer specification and statuses have been changed (step S 3 ). When the printer specification and statuses have been changed, the image server rewrites the RAM in the server (step S 4 ), and the process returns to step S 3 . 
   When the printer specification and statuses have not been changed, the image server  11  checks whether or not an image file registration request has been sent from a user (step S 5 ). When an image registration request has been received, the image server  11  checks whether or not the data is a file with password (step S 15 ). If it is not a file with password, the process proceeds to step S 6 , at which the image file is registered, with an image ID, in the image server, and a job setting screen is transmitted to the user&#39;s personal computer (step S 6 ). Then the process returns to step S 3 . If it is determined at step S 15  that the data is a file with password, the process proceeds to step S 16 , at which a screen asking whether or not the data is to be registered is displayed on the terminal. At step S 17 , if an instruction to register the data is returned from the terminal, the process returns to step S 6 . On the other hand, if an instruction not to register the data is returned from the terminal at step S 17 , the process returns to step S 3 . 
     FIG. 14  is an example of an inquiry screen for checking whether or not an image with password is to be registered, displayed at step S 16 . 
   If an image registration request has not been received, it is checked whether or not a job has been received from a user (step S 7 ). When a job has been received, it is checked whether or not the print job is executable (step S 8 ). 
   If the print job is not executable, information indicating that the job is unexecutable is transmitted to the user, and the job setting screen is sent to the user for re-setting of the job (step S 9 ). On the other hand, if the print job is executable, the charge of the execution of the job is calculated. Then, a job ticket for checking the job setting including the calculated charge amount is transmitted to the user (step S 10 ). 
   At step S 7 , when a job has been received, it is checked whether or not the user has approved printing and whether or not it is the print due date (step S 11 ). If it is not the print due date, the process returns to step S 3 . 
   If it is the print due date, the process proceeds to step S 18  at which it is determined whether or not the data to be outputted is data with password. If it is data without password, the process proceeds to step S 12 . On the other hand, if it is determined at step S 18  that the data is data with password, a request for password input is sent to the terminal at step S 19 . Then at step S 20 , it is determined whether or not the input password is correct. If the password is wrong, the process returns to step S 3 . 
   If the password is correct, the process proceeds to step S 12 , at which it is checked whether or not the job is test printing. If it is determined that the job is test printing, promotion data is called from the promotion file, and the promotion data and the print job data are transmitted to the printer (step S 14 ). If it is determined that the job is not test printing, the job data is transmitted to the printer (step S 13 ). 
   At step S 19 , a password input screen as shown in  FIG. 10  is displayed on the terminal. For document discrimination by the user, at least one of data name to be printed, server name holding the data, user name who registered the data, account name of data registration, date of registration, and time of registration, can be displayed on the terminal such that the user inputs a password in accordance-with the document. 
   &lt;Operation of Print System&gt; 
   (Registration without Password) 
     FIG. 11  is a timing chart showing the flow of registration of image data without password in the image server  11 .
     (i) The image server  11  inquires about the information and statuses as shown in  FIG. 6  on the printer side.   (ii) The result of inquiry in (i) is returned from the printer to the image server  11 . The image server  11  obtains the information such as functions, specifications and statuses of the plural printers managed by the server as a printer server (see  FIG. 6 ).   (iii) The user edits image data inputted from the scanner and/or digital camera, and/or generated on the personal computer, then transmits the image data to the image server  11  to register the image data there. When the image data is registered in the image server  11 , image IDs are set for the respective registered images. The image server  11  side manages the image IDs and image data respectively linked with each other (see the image memory in  FIG. 3 ).   (iv) When the image data has been registered, it is determined whether or not a password is attached to the data. Since a password is not attached to the data, the job setting screen for the registered image is transmitted from the image server  11  side to the user terminal  1 . For example, a setting screen as shown in  FIG. 8  is sent. The user makes selections utilizing the setting screen for a function to be used.
 
(Registration With Password)
   
     FIG. 12  is a timing chart showing the flow of registration of image data with password in the image server  11 .
     (i) The image server  11  inquires about the information and statuses as shown in  FIG. 6  on the printer side.   (ii) The result of inquiry in (i) is returned from the printer to the image server  11 . The image server  11  obtains the information such as functions, specifications and statuses of the plural printers managed by the server as a printer server (see  FIG. 6 ).   (iii) The user edits image data inputted from the scanner and/or digital camera, and/or generated on the personal computer, then transmits the image data to the image server  11  to register the image data there. When the image data is registered in the image server  11 , image IDs are set for the respective registered images. The image server  11  side manages the image IDs and image data respectively linked with each other (see the image memory in  FIG. 3 ).   (iv) When the image data has been registered, it is determined whether or not a password is attached to the data. As a password is attached to the data, a screen for the user to determine whether or not the data is to be registered to the terminal  1 . (see  FIG. 14 ).   (v) The user of the terminal  1  notifies the image server  11  whether or not the data registration is to be continued.   (vi) If an instruction of registration has been received from the user, the job setting screen as shown in  FIG. 8  is sent to the terminal.
 
(Output with Password)
   
     FIG. 13  is a timing chart showing the flow when output instruction is made to output image data with password.
     (viii) The image server  11  returns data, upon reception of the job from the user, as a job ticket. The job ticket includes the user ID, a job ID and a document ID.   (ix) Upon job output, the job ticket is sent to the server, thereby the data is outputted from the image server  11 . If the once-received job is to be changed, the job can be changed by re-utilizing the job ticket data and transmitting the job ticket to the image server  11 .   (x) Since it is determined that a password is attached to the data, the image server  11  transmits a password input screen as shown in  FIG. 10 .   (xi) The user of the terminal  1  inputs a password and transmits the screen to the image server  11 .   (xii) The image server  11  transmits the result of changed job setting and charge amount, similar to that shown in  FIG. 9 , to the user terminal.   (xiii) The operation is the same as (vii) in  FIG. 5     (xiv) The operation is the same as (viii) in  FIG. 5     (xv) On the due date of printing, the image server  11  transmits the job ticket to the printer in preparation for printing. On the printer side, when the user inputs user authentication information such as the job ID and the password into the printer, printing becomes possible. The print output time is determined in accordance with determination of payment. That is, upon determination of payment by using a coin vendor, charging to the user&#39;s credit card, charging to a particular bank account, payment by electronic money, or the like, printing is started.   (xvi) When the printing has been completed, the printer sends information indicating the completion of printing to the image server  11 .   
   Note that in the present embodiment, the present invention is described as a print system, however, the present invention is not limited to the print system. The invention is a technique for registration of data in a server and reading the registered data, therefore it is applicable to other systems, and the other systems are included in the invention. 
   Further, the object of the present invention can also be achieved by providing a storage medium (or recording medium) holding software program code for performing the aforesaid processes to a system or an apparatus, reading the program code with a computer (e.g., CPU, MPU) of the system or apparatus from the storage medium, then executing the program. In this case, the program code read from the storage medium realizes the functions according to the embodiment, and the storage medium holding the program code constitutes the invention. Furthermore, besides aforesaid functions according to the above embodiment are realized by executing the program code which is read by a computer, the present invention includes a case where an OS (operating system) or the like working on the computer performs a part or entire actual processing in accordance with designations of the program code and realizes functions according to the above embodiment. 
   Furthermore, the present invention also includes a case where, after the program code read from the storage medium is written in a function expansion card which is inserted into the computer or in a memory provided in a function expansion unit which is connected to the computer, CPU or the like contained in the function expansion card or unit performs a part or entire process in accordance with designations of the program code and realizes functions of the above embodiment. 
   In a case where the present invention is applied to the aforesaid storage medium, the storage medium stores program code corresponding to the flowcharts described in the embodiment.
