Secure printing system and method for the same

Abstract

The present invention provides a secure printing system, which includes: a client PC for creating print data for secure printing; one or more printers for performing printing; authentication data acquisition means provided for each printer , for obtaining the authentication data of the user who created the print data; and the print control PC, wherein the following steps are performed: if the client PC creates the print data, the print data is kept in the client PC, and at least the authentication information about the user is Notify to the print control PC; If the authentication data acquisition device obtains the authentication information about the user, then the authentication information is sent to the print control PC along with the information about the corresponding printer; the print control PC uses these authentication information to perform authentication; if the authentication is successful, The print control PC then notifies the client PC of print approval together with information about the printer; the client PC sends print data to the printer; and the printer executes printing.

Description

technical field [0001] The present invention relates to a secure printing system and a secure printing method, and more particularly, to a secure printing system and method in which, even when a specified printing system becomes unavailable for some reason, it is possible to still print regardless of the difference in mode Use another printer to perform printing. Background technique [0002] In an office environment or similar environment with a network, a configuration in which a single printer is shared by multiple users is often used. In such an environment, when a shared printer is used to print confidential documents including personal information such as archival records and payment statements, company trade secrets, or property information, other users of the printer may view the documents. [0003] That is, since normal printers start printing as soon as the print job is sent, any user printing a confidential document needs to walk up to the printer immediately aft...

Problems solved by technology

[0008] However, the problem with the system in Patent Document 2 is that, since if the printer that received the print instruction is in use or malfunctions, when the print job is transferred to a printer that does not have any authentication function, the printed material may be sent out. seen by someone other than the user who printed the command, so security cannot be guaranteed

Therefore, considering the use of a program that starts printing after the user who sent the print instruction has been authenticated, the system has a disadvantage in that printing cannot be performed unless the user instructs another printer having an authentication function

[0009] Also, given the need to reduce the threat of carrying confidential documents or data created when a confidential document is created at a first location and then printed at a second location, there is no way to know if the second location is connected if the print is not within the same network The printer, therefore, in conventional systems, cannot give instructions to the printer
