June 24, 2014

By a News Reporter-Staff News Editor at China Weekly News -- A patent application by the inventor Mitsui, Akihiro (Kawasaki-shi, JP), filed on November 26, 2013, was made available online on June 12, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to Canon Kabushiki Kaisha.

The following quote was obtained by the news editors from the background information supplied by the inventors: "Aspects of the present invention generally relate to an information processing apparatus, a control method, and a storage medium.

"Printers have a secure printing function, according to which the printers store a received print job, and print the stored print job if a correct password is input with use of an operation panel of the printers. Then, printer drivers can transmit a print job containing user information, such as a password, to instruct the printer to carry out secure printing. Japanese Patent Application Laid-Open No. 2010-218287 discusses that print setting data containing a password is generated to realize secure printing.

"However, if user information, such as a password, is stored as a part of the print setting data as discussed in Japanese Patent Application Laid-Open No. 2010-218287, confidentiality of the user information in the print setting data may decrease depending on an operation environment of the information processing apparatus."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventor's summary information for this patent application: "Aspects of the present invention are generally directed to preventing confidentiality of user information from decreasing.

"According to an aspect of the present invention, an information processing apparatus, which is configured to generate a print job interpretable by an image processing apparatus, includes a management unit configured to manage user information in such a manner that the user information is unable to be acquired using an authority different from a user authority, a control unit configured to control a printer driver, and a setting unit configured to set an authority of the control unit to the user authority of a user that issues an instruction for print processing. The control unit acquires the managed user information using the set user authority. A print job generated based on the acquired user information is transmitted to the image processing apparatus.

"Further features of the present disclosure will become apparent from the following description of exemplary embodiments with reference to the attached drawings.


"FIG. 1 is an example of a block diagram illustrating a configuration of hardware and software of a computer system.

"FIG. 2 illustrates an example of a configuration of a network to which a client, a server, and a printer are connected.

"FIG. 3 is an example of a block diagram illustrating a configuration of a v4 driver print processing system.

"FIG. 4 illustrates an example of a start menu of an operating system.

"FIG. 5, which is composed of FIGS. 5A and 5B, illustrates a sequence for storing user information into a property bag.

"FIG. 6 illustrates an example of a screen of a print dialog.

"FIG. 7 illustrates an example of a screen of a device application.

"FIG. 8 illustrates an example of information stored in the property bag.

"FIGS. 9A and 9B are flowcharts illustrating print processing.

"FIG. 10 illustrates a sequence for storing the user information into the property bag.

"FIG. 11 illustrates an example of the screen of the device application."
