About 25 percent of the Alexa top 10,000 websites have browser fingerprinting scripts deployed.

 

A browser fingerprinting script is a piece of JavaScript code that runs in a web page and works by testing for the presence of certain browser features.

 

Browser fingerprinting is now commonly used by online advertisers as a next-generation user-tracking mechanism. Advertisers perform various types of fingerprinting operations, create one or more "fingerprints" for each user, and use these "fingerprints" to access information on the Internet. other sites that track users.

 

Undoubtedly, this kind of hype by advertisers has seriously violated user privacy. Browser manufacturers such as Firefox, Chrome, Opera, Brave, and TorBrowser have all detected and blocked these types of malicious codes.

 

Earlier, a research team from Mozilla and several universities analyzed how popular browser fingerprinting scripts are used by website operators today.

 

They used a self-developed machine learning toolkit called FP-Inspector to scan and analyze the 100,000 most popular websites on the Internet according to the Alexa web traffic ranking. According to the survey data, more than 10% and 25% of the top 100,000 and top 10,000 websites in Alexa have implemented browser fingerprinting respectively.

 

However, the researchers also point out that while many websites currently use browser fingerprinting, not all scripts are used for tracking. Since automated bots tend to have the same or similar fingerprints, and fingerprinting scripts are a reliable way to detect automated behavior, some fingerprinting scripts are used to detect fraudulent activities.

 

So what does browser fingerprinting include? Browser fingerprinting is a powerful tool that can collect monitoring methods on parameters such as browser version and type, operating system, language, time zone, screen resolution, and browser plug-ins. Websites identify users based on these parameters (known as browser fingerprinting) and track certain user behaviors.

 

1. Ordinary fingerprint

 

Including Cookie, Session, Evercookie, FlashCookies.

 

2. Basic fingerprint

 

Includes hardware type (Apple), operating system (MacOS), user agent (useragent), system fonts, language, screen resolution, browser plug-ins (Flash, Silverlight, Java, etc.), browser extensions, browser settings (Do- Not-Track, etc), time zone difference (BrowserGMTOffset) and many other information.

 

3. Advanced fingerprint recognition

 

Contains Canvas fingerprints, AudioContext fingerprints, WebGL fingerprints, etc.

 

4. Hardware fingerprint

 

Including media device fingerprint recognition, GPU plug-in, Pepper3D rendering, etc.

 

5. Comprehensive fingerprint

 

Including WebRTC (WebReal-TimeCommunication, webpage real-time communication), MediaStream, RTCPeerConnection, RTCDataChannel, etc.

 

How to prevent browser fingerprint collection?

 

If you do not have enough expertise, or if you change your browser information frequently, browser fingerprinting can identify you 100% of the time. Therefore, you need professional software like Bitcoin Account Browser to fake your browser fingerprint.
