Problems solved by technology

[0013] The present invention provides a method and device for embedding a watermark in a webpage document. On the premise that it is invisible, the necessary page text content is obtained by analyzing the content of the webpage document, and the text content of the page is modified by a digital watermarking algorithm to embed the watermark information. It is used to solve the problems of poor visual effect, low security and weak anti-copying ability of the page watermark in the prior art

Embodiment Construction

[0050] figure 1 It is a schematic diagram of the implementation process of a method for embedding a webpage document page watermark described in the embodiment.

[0051] S101: When a user logs in a web browser to access a web application system page, the HTTP protocol data packet of the web application is intercepted by a data interception method.

[0052] In order to embed document traceability information in real time when the web browser opens the web application system page document, it is necessary to intercept the corresponding content data before the browser normally displays the page document, and embed the watermark information after modification. Since most of the current internal office Web application systems use the HTTP protocol, it is necessary to intercept the HTTP protocol data of the Web application first. The specific content includes: response line, response header, and response body.

[0053] The response line generally consists of protocol version, status code a...

Abstract

The invention relates to a webpage document watermark embedding method and device. The method comprises the steps that 1, when a user logs in a web browser to access a web application system page, intercepting an HTTP protocol data packet of a web application; step 2, analyzing an HTTP response header data packet in the intercepted HTTP protocol data packet to obtain HTTP response content data; 3,analyzing the HTTP response content data, and embedding watermark information by modifying the page content data; and 4, returning the page file embedded with the watermark to the browser for normalpage content analysis and page content rendering. According to the method, the embedded text traceability tracking information is visually invisible, so that visual interference caused by an existingscreen dominant watermarking technology is avoided; and meanwhile, the watermark information is embedded by taking the text content in the webpage document as a carrier, is not easy to erase manually,and can resist screen shooting or screen capture, so that the safety performance is higher.

Description

Technical field [0001] The invention belongs to the technical field of digital watermarking and information hiding, and relates to a method and device for embedding a webpage document watermark. Background technique [0002] With the continuous development and rapid advancement of e-government, e-commerce and paperless office technology, various network application systems have been widely promoted and applied. For example, in mobile office, people have used smart terminals to realize seamless integration of office staff with the company’s existing OA office system, asset system, production management system, marketing management system and other applications. Through mobile terminal equipment, they can carry out enterprises anytime, anywhere. Office, such as browsing notifications, news, important events, documents, etc., sending and receiving text messages, and mobile queries, etc. The network application system has greatly improved the efficiency of information flow and proce...
