Printed file whole-course state tracing method and system

Abstract

The invention provides a printed file whole-course state tracing method and system, and the method comprises the steps that a user terminal installs a printing drive module, and a user reports a printed file to a printing application module through the printing drive module; the printing application module reports a to-be-printed file to a superior printing approval module of a current user, and acorresponding authority leader approves the to-be-printed file; after the corresponding authority leaders approve the files needing to be printed through the printing approval module, an invisible watermark module signs an invisible watermark on the file to be printed and returns the file to be printed to the user terminal; a printing driving module of the user terminal verifies the invisible watermark of the file to be printed, and reminds the user to print the file after confirming that the watermark is correct; and the user confirms printing, and the printing driving module completes printing of the file and generates a printing log. According to the invention, the whole-process state tracing of the printed file can be realized.

Description

technical field [0001] The invention belongs to the technical field of data security, and relates to a method and a system for tracing the whole state of a printing file. Background technique [0002] With the rapid development of Internet technology, corporate offices have already entered the era of information-based office. The amount of information stored in office terminals is increasing, and the risk of information leakage is also increasing. Information is output from the computer terminal to the printer, and then from the printer to paper documents. During this process, there is a great hidden danger of information security leakage. Once the supervision is not proper, it may bring unexpected losses to the enterprise. For example, printed documents such as design drawings and customer information may involve national interests, corporate interests, and personal interests. Once leaked, it is difficult to trace the source of the take-out and the relevant responsible pers...

Problems solved by technology

Information is output from the computer terminal to the printer, and then output from the printer to paper documents. In this process, there is a great hidden danger of information security leakage. Once the supervision is not proper, it may bring unexpected losses to the enterprise.

For example: printed documents such as design drawings and customer information may involve national interests, corporate interests, and personal interests. Once leaked, it is difficult to trace the source of the take-out.

[0003] In the existing system, the control of printed documents is generally limited to the aspect of printing control. After the printed documents are printed, it is impossible to effectively track the status. Once there is a leak, it is difficult to trace the source and route of the leak. The development of work brings obstacles
