Browser fingerprinting is a tracking technology that websites use to collect users' personal information. This method forms a user's unique online "fingerprint" by obtaining the user's browser type and version, operating system, plug-ins, time zone, language, screen resolution, and other settings.
Modern websites often use scripts to implement their functions, which run in the background and extract various information about the device and browser. When this information is aggregated, it forms a unique identifier that allows websites to track users across different sessions and Internet platforms.
Many website owners and advertising networks use browser fingerprinting to perform cross-site tracking to obtain users' private data, such as search history, shopping preferences, and news interests.
Online fingerprinting technology
Online fingerprinting uses a variety of technologies to identify individuals with high accuracy, including:
1. Canvas fingerprinting: Using the HTML5 canvas element, forcing the browser to render images or text without the user's sight. The browser's rendering method provides detailed information about font styles, graphics cards, drivers, web browsers, and operating systems.
2. WebGL and rendering fingerprinting: These technologies require the browser to render images in the background, and infer the device's hardware and graphics system information through these images.
3. Device fingerprinting: This includes not only browser fingerprinting, but also focuses on discovering all media devices on the computer and their unique identifiers, including internal audio and video components and connected peripherals.
4. Audio fingerprinting: This technology detects the way the device plays sound, and the sound waves generated can reveal information about the device's audio system, including the specifications of the driver and sound card.
To protect yourself from online fingerprinting, users can consider using a privacy-protecting browser such as BitBrowser.
BitBrowser is a multi-account and anti-association management tool that provides an independent browsing environment for each account, including different IP addresses and time zones, and virtualizes multiple devices into a single browser profile, thereby obfuscating digital identities and making it difficult for websites to collect information to build your online fingerprint.
How to protect yourself from browser fingerprinting?
1. Use a VPN: A virtual private network (VPN) hides the IP address, and the Internet server can only see the VPN's IP address (which may be shared by other users). However, relying on VPN alone cannot completely protect users from browser fingerprinting, as websites can also detect other information such as cookies, canvas, audio, user agent, etc.
2. Use VPS: Virtual Private Servers (VPS) provide a hosting option that costs less than dedicated servers, but provide better reliability and security than shared hosting. Users have root access on VPS and can freely install applications and change environment settings. However, using VPS may not be very convenient, especially in teamwork, and if multiple VPS are required, the cost will be relatively high.
3. Use anti-detection browsers: Anti-association browsers such as BitBrowser, mulogin, Linken Ball Browser effectively protect users from identification attempts. These browsers support settings for numerous fingerprint components, such as time zone, WebRTC, geolocation, language, user agent, resolution, font, do not track, Flash and port protection, etc.
In addition to the above methods to cover your fingerprint on the Internet, you can also consider using security plugins, disabling JavaScript and Flash, installing anti-malware tools, etc. To sum up, the most effective way is to use an anti-association browser (such as BitBrowser). These tools can effectively block browser fingerprints in most cases.
