What is WebRTC fingerprinting?
WebRTC fingerprinting is a topic that is becoming increasingly important in the world of online privacy and security. Let's find out with Genlogin through the article below.

1. A quick introduction to WebRTC fingerprinting

1.1. The definition

WebRTC (Web Real-Time Communication) is a technology that supports direct communication (peer-to-peer) between browsers, allowing us to transmit audio, video and data directly between two browsers without going through an intermediary server. This technology is already built into most modern browsers like Chrome, Firefox, Opera and Edge.(According to Tech Target) WebRTC can also be used to collect user browser information, this is known as WebRTC Fingerprinting. When a website requests access to the user's camera or microphone, the browser displays a window asking for access. However, through WebRTC, the website may also collect information about the user's browser, such as screen resolution, CPU speed, browser version, and operating system. WebRTC fingerprinting works by exploiting the fact that each browser implementation of WebRTC is slightly different. By using JavaScript code to access the WebRTC APIs and examining the details of the responses, it is possible to create a unique fingerprint of a user's browser.

1.2. The impact of WebRTC fingerprinting in the digital age

One of the key aspects of WebRTC fingerprinting is that it is much more difficult to block or prevent than other forms of fingerprinting. Because WebRTC is an integral part of modern browsers, blocking or disabling it can break the functionality of many websites and web applications. Additionally, because browser fingerprinting is based on specific implementation details of the browser, simply using a different browser or device may not be enough to avoid being tracked.
The most significant concern with WebRTC fingerprinting is that it can be used to link a user's online activity across multiple devices and browsers. Because the fingerprint is based on implementation details that are unique to each device and browser combination, it can be used to create a persistent identifier that is very difficult to erase or change.

2. Some tips to lower the risk of WebRTC fingerprinting

There are several ways to minimize the danger of WebRTC in fingerprints as follows:
  • Disable WebRTC: The simplest way to prevent WebRTC Fingerprinting is to disable this function in the browser. This will prevent any information from being collected through WebRTC, but may also prevent communication functions directly in the browser.
  • Use WebRTC blocking application: There are many WebRTC blocking applications that can help users prevent this activity on their browser. This helps users to keep their privacy and security when accessing the internet.
  • Utilize anonymous browsing: Some anonymous browsers like Tor or Brave are using technology to reduce the possibility of fingerprinting. However, using an incognito browser can reduce access speed and user experience.
  • Opt for an antidetect browser: There are many browser extensions that can help users prevent browser fingerprinting like Genlogin antidetect browser by minimizing the amount of information collected about their browser. However, it should be noted that some of these extensions may affect browser performance.

3. Conclusion

In summary, WebRTC fingerprinting is a method of collecting browser information of users on the internet in a dangerous technique through WebRTC technology. However, users can minimize the possibility of being tracked and monitored by disabling WebRTC, using a WebRTC blocking application, using an incognito browser, or using fingerprinting blocking extensions. Preventing fingerprinting helps users protect their privacy and security when accessing the internet.
