Abstract

The invention discloses a Web user privacy protection system and method based on an information stream tag, and belongs to the field of Internet safety. The system comprises a tag adding module and a tag detection module, wherein a novel access control tag model applied to a Web environment is designed in the tag adding module for adding a tag to a message transmitted between a Web component and a Web component; when the Web component comprises a third-party code, a light-weight process is designed for isolating a third-party dangerous code; meanwhile, the tag is aimed to design a message transferring rule to track a user privacy information message so as to track the user privacy information message. The invention also realizes the Web user privacy protection method based on the information stream tag. The technical scheme disclosed by the invention is suitable for Web applications of which the safety level needs to be improved, wherein the Web applications have sensitive user information. The Web application can be free from a situation that the third-party code is damaged, and the privacy information of the user can be protected.

Description

technical field [0001] The invention belongs to the field of Internet security, and more specifically relates to a privacy protection system and method for Web users based on information flow labels. Background technique [0002] In order to provide users with rich services, including map navigation, online payment, etc., current web applications integrate a large number of third-party codes. But because these services often require access to users' private information, developers and users must fully trust them not to leak private information. Many recent studies have shown that these third-party codes can cause a series of serious hazards, such as tracking user browsing records, obtaining user form input data, stealing cookies and private data, and even hijacking session information to forge user requests. [0003] Today's browsers rely on Same Origin Policy (SOP), Cross-Origin Resource Sharing (CORS), Content Security Policy (CSP) and other security mechanisms to prevent...
