Description

  The present invention relates to a printer driver, and more particularly to a printer driver for a printing system in which a document at the time of printing is printed based on a plurality of printing restriction keywords.

In a printing system that outputs print data created by a host device onto a sheet by a predetermined printer, it is a problem to prevent leakage of confidential information. For example, in Patent Document 1, an element and its element name are extracted from a print document, and compared with a keyword set inside to determine whether or not they match each other. A technique for replacing an element having a matching element name with an outputable element and outputting a document including the replaced element is shown.
JP 2003-303063 A

In printing systems, it is desired to secure the security of printed documents, but it has been difficult to accurately and easily set security levels such as confidential, confidential, and top secret, or settings for each department. It was.
According to the present invention, in a printer driver in which a print restriction keyword is set before installation, it is determined whether a document at the time of printing matches a plurality of print restriction keywords, and if they match, the document is not printed. Another object of the present invention is to provide a printer driver capable of finely printing a printed document.

In order to achieve the above object, the invention described in claim 1 is provided with a print restriction keyword file that restricts printing after installation and can be edited by text in a file group constituting a printer driver before installation. It is characterized by that.
The invention described in claim 2 recognizes the set printing restriction keyword file and reads the information of the printing restriction keyword, and stores the information of the printing restriction keyword read by the input means as internal data. And a storage means.
According to a third aspect of the present invention, when printing is performed based on the information of the print restriction keyword, a determination unit that determines whether or not a print document matches the print restriction keyword, It is characterized by comprising a restricting means for restricting printing and a display means for displaying that the printing is restricted.
According to a fourth aspect of the present invention, a password for canceling the print restriction is added to the print restriction keyword file for each print restriction keyword.
According to a fifth aspect of the present invention, there is provided means for releasing a print restriction and permitting printing by inputting a password for releasing the print restriction of the print restriction keyword file at the time of printing.
The invention according to claim 6 is characterized in that a computer-readable recording medium in which the printer driver according to claim 1 is recorded as a program is the main feature.

  The printer driver of the present invention has a print restriction keyword file that restricts printing after installation and can be edited with text in the printer driver configuration file group before installation, so that the security of the printed document is finely detailed. Will be able to.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a specific example of a print restriction keyword file that restricts printing by a printer driver after installation and can be edited with text. By having such a print restriction keyword file in the printer driver configuration file group before installation, when printing is performed after installation, printing is restricted according to the print restriction keyword.
In the case of this specific example, printing of a document in which the top secret, department 1, and department 2 are described is restricted.
FIG. 2 is a flowchart regarding reading of a print restriction keyword file and data registration. When the printer driver is installed (S1), if a print restriction keyword file is recognized (Y in S2), it is read and stored as internal data (S3). If the print restriction keyword file is not recognized at the time of installation (N in S2), it is not read or saved as internal data (S4). Then, the installation of the printer driver is finished (S5).
FIG. 3 is a flowchart for restricting document printing during printing. When the printer driver performs printing based on the print restriction keyword information (S1), it is determined whether or not the document to be printed matches a plurality of print restriction keywords. If they match (Y in S2), the document is printed. And reports to the user that printing is restricted (S3). If there is no matching keyword (N in S2), printing is performed as usual (S4).

FIG. 4 shows a specific example of a print restriction file in which a password that enables printing by releasing the print restriction keyword is added. By having such a print restriction keyword file in the printer driver configuration file group before installation, printing can be restricted according to the print restriction keyword after installation, and the restriction can be released with a password as necessary. .
In the case of this specific example, the printing of the document in which the top secret, department 1 and department 2 are described is restricted, but can be canceled by the password of himitu, busyo1 password, busyo2 password. By doing so, it is possible to print only the document for which the user has his authority.
FIG. 5 is a flowchart for canceling restrictions on document printing during printing. When the printer driver performs printing based on the print restriction keyword information (S1), it is determined whether the document to be printed matches a plurality of print restriction keywords. If they match (Y in S2), the document is printed. If you want to print after canceling the print restriction and printing, you must enter the password to remove the print restriction keyword on the screen to remove the print restriction keyword (Fig. 6). (Y in S3, Y in S4) Printing is performed as usual (S5).
If there is no matching keyword (N in S2), printing is performed as usual (S5). In addition, when there are a plurality of printing restriction keywords, it is necessary to input a password for cancellation for each keyword. If the password is not correctly entered, the screen returns to the password entry screen (see FIG. 6). If N in S3, printing is not executed (S6).

The printer driver of the present invention can restrict the printing of a document including the printing restriction keyword when the user prints the document by the administrator freely setting the printing restriction keyword before the installation. In addition, the administrator can set keywords such as confidential, confidential, confidential, and department names that are always described in internal documents as printing restriction keywords. In-house document security.
In addition, the printer driver of the present invention recognizes the print restriction keyword file set by the administrator at the time of installation, reads the information of the print restriction keyword, and saves it as internal data, thereby printing the document when the user performs printing. The keyword can be restricted.
The printer driver according to the present invention can prevent printing when a user prints a document and a keyword that the administrator wants to restrict printing is included in the document. Also, by reporting that printing is restricted by the administrator, the user can be informed that printing of the document is restricted for in-house document security.
In the printer driver according to the present invention, the administrator can set a print restriction keyword and a password for each print restriction keyword before the installation, so that the user can release the print restriction of the document including the print restriction keyword. This allows a person with the proper authority to print a document that requires the proper authority.
The printer driver of the present invention is a driver in which the print restriction keyword is set, and when a user having a special authority to recognize a password that can release the print restriction prints a document that matches the print restriction keyword, the print restriction keyword is printed. Can be printed. This allows the user to print a document that suits his authority.
