Abstract

The invention belongs to the field of information security techniques and provides a printing security monitoring and auditing system based on a virtual printing technique aiming at solving the problems that the printing behavior and the printing content are hard to monitor, unauthorized printing and skip-level printing cannot be prevented and the like in the existing printing management method. The printing security monitoring and auditing system comprises a server, at least one ordinary client, at least one approval client, a printing controller and a printing machine, wherein the clients are divided into the ordinary clients and the approval clients; and all ordinary clients and all approval clients are connected with the server, the printing controller is connected with the server and the printing machine is connected with the printing controller. By adopting the windows virtual printing technique, the optical character recognition (OCR) technique, the equipment intelligent control technique and the like, the printing security monitoring and auditing system realizes the monitoring and management of documents at a full life cycle which comprises printing application, approval, output, recovery, destruction and the like, and can form complete printing logs for review.

Description

technical field

[0001] The invention belongs to the technical field of information security and confidentiality, and in particular relates to a printing security monitoring and auditing system based on virtual printing technology. Background technique

[0002] With the continuous improvement of the country's security and confidentiality requirements for government, military and other secret-related enterprises and institutions, the importance of security audits of printing behavior and content has become increasingly prominent. According to the relevant requirements of the State Security Bureau, printing security monitoring and auditing mainly involves three aspects: ensuring the security and confidentiality of printing content; monitoring printing behavior and printing content to prevent unauthorized printing behavior and content leakage; being able to audit printing behavior and print content.

[0003] However, at present, most secret-related units still adopt traditional...
