Problems solved by technology

[0009] Under the current printing monitoring method, all the printers to be monitored can only be required to perform printing monitoring when they are all disabled or fully enabled. In this case, if all the printers to be monitored are disabled, normal printing cannot be performed during the monitoring process business; if all the printers to be monitored are enabled, some printers with uncertain legitimacy have high insecurity in performing printing business

Embodiment 1

[0031] Such as figure 1 As shown, it is a schematic diagram of a printing monitoring method in an embodiment of the present invention, and the method includes the following steps:

[0032] Step 101: Before the printer to be monitored executes printing services, determine the attribute information of the printer to be monitored.

[0033] Before this step is executed, the WINAPI filtering dynamic library can be injected into a specific process that has been started, such as a Windows system process.

[0034] The WINAPI filtering dynamic library can determine the printing business in the injected process, filter the WINAPI related to printing in the injected process, and decide whether to enable or disable the use of the printer according to the preset policy, that is, through the filtering function Complete authorization and monitoring of printers and logging of printed jobs.

[0035] Since the WINAPI filtering dynamic library has the above functions, before the host printer e...

Embodiment 2

[0072] Under the same inventive idea as the embodiment of the present invention, Embodiment 2 of the present invention also provides a printing monitoring system, such as Figure 4 As shown, the system includes: an attribute information determination module 11, a policy management module 12, a comparison module 13 and a monitoring module 14, wherein: the attribute information determination module 11 is used to determine the Attribute information of the monitored printer; the policy management module 12 is used to determine the attribute information in the preset printer policy list; the comparison module 13 is used to compare the determined attribute information of the printer to be monitored with the attributes in the printer policy list The monitoring module 14 is used to allow the printer to start the printing service according to the comparison result, or to prohibit the printer from starting the printing service.

[0073] The monitoring module 14 is specifically configure...

Abstract

The invention discloses a method and a system for monitoring printing. The method comprises the following steps of: comprehensively monitoring a printing service to be executed by a printer when the printer of a host computer is monitored; performing validity authorization aiming at attribute information of each printer; executing the printing service only by the printer which receives validity authentication; if the printer does not receive validity authentication, forbidding starting the printing service and determining all the started processes in the process list of the printer to be monitored; injecting a WINAPI filtering dynamic library into the started processes; determining the printing service started by a user; and before the exertion of the printing service started by the user, injecting the WINAPI filtering dynamic library into the printing service process started by the user. The WINAPI filtering dynamic library is provided for determining the printing service injected in the process. Therefore, the method and the system realize comprehensive and fine-grained monitoring on the printer, and improve the reliability of printing monitoring on the premise of not influencing the normal printing service.

Description

technical field [0001] The invention relates to computer technology, in particular to a printing monitoring method and system. Background technique [0002] At present, printing equipment is widely used in office systems, which is convenient but also poses a threat to the leakage of confidential information. In order to monitor the security of printing equipment in real time, a monitoring system based on host printing and a monitoring system based on network printing have been proposed. system. [0003] At present, the monitoring system based on host printing adopts the printing pool monitoring API development interface, and the monitoring steps are roughly as follows: [0004] Step 1: Obtain a list of instances of printers to be monitored. The implementation of this step is to call the print list (EnumPrinters) statement of the WINAPI (Windows API, Windows Operating System Application Programming Interface) function. [0005] Step 2: Run the printer instance in the insta...
