Embodiment 1

[0064] like figure 1 As shown, it is a main flowchart of a method for file information output anti-disclosure and traceability, including the following steps:

[0065] S101. First, deploy and install a file information output operation monitoring service system at the file information output terminal.

[0066] Among them, the file output terminal equipment specifically includes computer monitors, tablet computer monitors, mobile phone terminal monitors, printers, plotters, video output devices, magnetic recording devices, etc.

[0067] S102. When the file information output terminal performs a file information output operation, the file information output operation monitoring service system automatically performs information leakage prevention processing in the file information output content.

[0068] Normally, the file information output operation includes: terminal screen display, electronic format document conversion and printout, wherein the electronic format document co...

Embodiment 2

[0135] This embodiment provides a system for file information output anti-disclosure and traceability, including the following parts:

[0136] User account information management module: It has a complete user account system, which can be connected to AD (active directory, active directory), LDAP (Lightweight Directory Access Protocol, lightweight directory access protocol) and other self-built systems within the user organization, and synchronize the organizational structure and user information;

[0137] Client monitoring service module: Deploy and install the file information output operation monitoring service system at the file information output terminal. When the file information output terminal performs the file information output operation, the file information output operation monitoring service system will automatically perform information prevention in the file information output content. Leakage processing, and at the same time call the watermark information embed...

Embodiment 3

[0143] This embodiment provides a method for embedding and extracting watermark information in electronic format document output, including the following steps:

[0144] Step 1, run the electronic document editing software system to open the electronic document, and read all content data in the document into the memory;

[0145] Step 2. After reading the user identity information and reading the system time in real time, generate watermark information through mixed coding to identify the traceability and tracking information of the document;

[0146] Here, the user information may be the login user account of the system, the MAC address of the device, the IP address, as well as artificially designated coding information, device serial number information, and the like.

[0147] Step 3: Dynamically embed watermark information in the document data read into the memory by means of watermark font replacement;

[0148] Here, the watermark information is embedded in the entire page ...

Abstract

The invention relates to a file information output anti-leakage and tracing method and system. The method comprises the steps of deploying a file information output operation monitoring service system in a file information output terminal; when the file information output terminal performs file information output operation, automatically performing information anti-leakage processing in file information output contents by the file information output operation monitoring system, wherein the anti-leakage processing includes the addition of invisible watermark information; performing one or more of screen switching, screen shooting, screen video recording, file copying and printout operations on file information of the file information output terminal; and converting carrier contents after file information output into image data in an electronic format, running a watermark information extraction identification program to detect the watermark information, and performing file information leakage tracing operation. According to the method and the system, the technical difficult problem of tracing after leakage of screen shooting and printout modes of the file information output terminal can be solved on the premise of not influencing the visual effect of right reading of users.

Description

technical field [0001] The invention belongs to the technical field of security document protection, relates to screen watermarking and printing watermark technologies of security documents, and in particular to a method and system for security document leakage prevention and source tracing. Background technique [0002] Electronic documents refer to written materials formed by people in social activities, which are carried by chemical magnetic materials such as computer disks, magnetic disks, and optical disks. They rely on computer systems for access and can be transmitted on communication networks. It mainly includes electronic documents, electronic letters, electronic reports, electronic drawings and so on. Electronic document security refers to the security of electronic documents in the process of production, transmission and use. Electronic document security includes electronic document file security and content security. [0003] In recent years, according to stati...
