Data safety printing control method based on virtual printer technology

Abstract

The invention discloses a data safety printing control method based on a virtual printer technology. The method comprises the following steps of (1), by the adoption of the virtual printer technology, monitoring a printing pool list in real time, realizing the monitoring of a printing task initiated by a virtual printer, and capturing a printing pool document generated by the printing task; (2), analyzing the obtained printing pool document; (3), carrying out the conversion of a user-defined document format on the analyzed printing pool document; and (4), controlling the document in the printing pool and starting the actual printing operation. According to the method, during a printing process, if any of the steps is subjected to illegal attacks, data cannot be printed, and the data leakage can be prevented. Therefore, by the adoption of the method, the safety control performance of printing is greatly improved, and the problems that information can be printed from an application layer and the data monitoring is easily subjected to illegal attacks are further solved.

Description

technical field [0001] The present invention relates to the fields of computer software system, geographic information system (GIS), computer aided design (CAD), computer cartography (CAC), information security, printing security, etc., and particularly relates to a method for secure printing control of a printer. Background technique [0002] At present, in the field of traditional printing security control technology, the printing data flow information is mainly monitored from the system application layer. [0003] However, the print monitoring module is only responsible for monitoring and does not participate in any printing control process. Traditional printing security control cannot ensure that data is always under security protection throughout the entire life cycle. [0004] In order to solve the above problems, a new method is needed, which can realize the [0005] The real-time monitoring method of printing tasks irrelevant to brand, model, and connection mode, an...

Problems solved by technology

The name is "a method and system for printing monitoring". At present, the printing control system relies too much on Windows applications, and there is no interlocking security mechanism with the printing driver layer, that is, it does not participate in the middle printing process control, even if the background monitoring program intercepts illegal printing. operation, the printing work can only be forcibly terminated after the printing event occurs, and the monitoring or monitoring of the printing process cannot be realized, which may easily cause data leakage
