Embodiment Construction

[0041] In order to make the purpose, solution and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] Fingerprint information can be obtained in two ways. One is obtained by executing codes in scripts or plug-ins, which is called active fingerprinting information. Information such as CPU model, time zone, installed plug-ins, whether cookies are available, etc.; the other is obtained by querying network streams, which is called passive fingerprinting information. Such as IP address, language, http header, etc. Some information can be obtained both through code execution and network streams, such as OS type, user agent, etc.

[0043] The following takes the analysis of basic browser information finger...

Abstract

The invention discloses a browser fingerprint detection behavior monitoring method. The method comprises the following steps: 1) rewriting an API that can be used for fingerprint detection, and addinga counting function; 2) requesting, by a browser, a page from a web server, replacing the API in a page script returned by the web server to the browser with the rewritten corresponding API, and thenreturning the modified page script to the browser; 3) when the rewritten API is called by the web server for execution, updating the execution times of the API, and then injecting a counting result in the page; 4) when the browser requests the page from the web server again, extracting a Cookie value from an HTTP header requested from the page, and transmitting the Cookie value to a target domain; and 5) determining a browser fingerprint detection behavior of the web server through the Cookie value in the target domain. By adoption of the browser fingerprint detection behavior monitoring method disclosed by the invention, a user can intuitively understand the degree of leakage of the own browser fingerprint.

Description

technical field [0001] The invention belongs to the field of network communication, and relates to a method for monitoring the browser fingerprint behavior of a Web site detection user, in particular to a Chrome extension-based browser fingerprint detection behavior monitoring method. Background technique [0002] With the development of Internet technology, there are more and more types of Internet applications, and the forms for users to participate in Internet activities are becoming more and more abundant, such as e-government, social networking, online shopping, online financial management, air ticket hotel reservations, instant messaging, etc. The popularity of Internet applications has greatly increased the ways to collect real information about users. The deeper the user's use of Internet applications, the higher the possibility that his real identity information will be collected by Internet companies, and may even be mastered by many different Internet companies. ...
