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 can not be printed, and the divulging of a secret can not be led to. 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 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 controlling printers for safe printing. Background technique [0002] At present, in the field of traditional printing security control technology, printing data flow information is mainly monitored from the system application layer. However, the print monitoring module is only responsible for monitoring and does not participate in any print control process. Traditional print security control cannot ensure that the data is always under security protection throughout its life cycle. [0003] In order to solve the above problems, a new method is needed that can realize a real-time monitoring method for printing tasks that has nothing to do with the format of the printed document, printer brand, model, and connection mo...

AI Technical Summary

Problems solved by technology

[0004] The printing control system in the above two patents 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 intermediate printing process control. Even if the background monitor program intercepts illegal printing operations, it can only After the occurrence, the printing work is forcibly terminated, and the monitoring or monitoring of the printing process cannot be realized, which may easily cause data leakage
