Watermark information adding method, server and system

Abstract

The invention discloses a watermark information adding method, which comprises the following steps of: receiving an access request sent by a client, and requiring the access request to access a network page on a network server identified by a domain name; obtaining a network page corresponding to the access request from the network server; adding a preset watermark request script into the obtainednetwork page, and returning the preset watermark request script to the client; receiving a watermark request sent by executing the watermark request script by the client; acquiring user information corresponding to the client, and generating a watermark generation script based on the acquired user information and a predetermined watermark request script; and sending the watermark generation script to a client, so as to execute the watermark generation script at the client to superpose watermark information on the web page. The invention further discloses a corresponding watermark informationadding server and system. According to the watermark information adding method, codes of the network server side are prevented from being modified, time cost is saved, and the watermark script can beprevented from being tampered easily.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for adding watermark information, a server and a system for adding watermark information. Background technique [0002] As enterprise data security is getting more and more attention, Data Leakage Prevention (DLP) has gradually become one of the most important security technologies in the market. During the implementation of the DLP, how to prevent information leakage during photographing has become an urgent problem to be solved by those skilled in the art. [0003] At present, for the important web application systems of companies such as OA, CRM, and big data platforms, adding user information watermarks on HTML pages is undoubtedly a better means of prevention, deterrence, and traceability. [0004] In the existing technology, the web system basically uses JavaScript code to add watermark information. This solution has the following disadvantages: Firs...

Problems solved by technology

[0004] In the existing technology, the web system basically uses JavaScript code to add watermark information. This solution has the following disadvantages: First, JavaScript code access to the business system is very complicated, and a large number of codes need to be modified, which is equivalent to customizing Second, since the JavaScript code of the watermark is accessed from the front end, it is easy to be bypassed, resulting in no security protection effect; third, the lack of an escape mechanism leads to If it cannot be loaded smoothly, it will directly affect the normal access of the origin site application, or the access speed will slow down
