What is browser fingerprint
User authentication method on the Internet
Fingerprint browser (Browser Fingerprint) replaces followed cookies. In the course of interacting with the site, the browser transmits information about its settings and computer configuration, according to which a unique 32-bit number is compiled, which is a unique identifier.

A computer is recognized by a digital fingerprint with an accuracy of 94%. The more metrics are taken into account when calculating a browser fingerprint, the more accurate it is. Browser fingerprint is a more advanced identification method than spyware cookie technology, which is outdated and easily bypassed by secure browsers.
There are online services on the network that allow you to recognize the fingerprint of the browser. To do this, set in the search query string: find out the browser fingerprint.
For what purposes Browser Fingerprint is defined
Site owners collect their visitors' browser fingerprints to:
- secure authentication,
- collecting comprehensive information about site visitors,
- targeted ad impressions,
- identification of anonymous unregistered visitors,
- for internal analytics and improving the usability of the web resource.
Today there are over 4 billion Internet subscribers in the world. Information about his interests, hobbies, preferences and other data is tied to the identified user in order to create individual advertising campaigns aimed at the needs of a specific person, to offer products of interest, informational articles and video materials.
It is possible that Browser Fingerprint databases are sold or shared with other organizations. At the same time, users cannot hinder the collection and accumulation of such digital data or influence their use.
Security experts regard the unauthorized collection of browser fingerprints as a breach of privacy. Identifying an Internet user without his knowledge and consent undermines the fundamental principle of the world wide web - anonymity, which gives a sense of freedom and security.
It is almost impossible to prevent or restrict the collection of browser fingerprints. If you want no one to be able to identify your fingerprint, do not use the Internet.
How to hide browser fingerprint
To hide the browser fingerprint, modify it by adjusting the operating system settings or changing the computer settings. Any changes will affect the fingerprint.
To change Browser Fingerprint manually, change one or more of the following settings:
- use a different user-agent,
- install or remove plugins and extensions,
- set a different screen resolution of the monitor,
- change the scaling of web pages,
- replace preferred fonts,
- choose a different time zone in Windows settings,
- change the operating system and system interface language,
- change browser configuration,
- disable geolocation in the browser (location determination),
- create a new user profile.
After modification, check if the browser fingerprint has changed using Internet services.
Changing the IP address on the network will not help to hide (change) the browser fingerprint. On the other hand, many people have standard default browser settings that have not changed over the years. Specific parameters, on the contrary, distinguish the computer from the general mass. Alternatively, you can get lost among the identical hundreds of thousands of non-unique browser fingerprints.
Antidetect browser with different fingerprints
Antidetect browser guarantees complete confidentiality. It modifies the browser fingerprint, allowing you to work with multiple accounts. These programs are paid with monthly subscriptions on average $ 25 - $ 100. Depending on the tariff, a set of different browser fingerprints is offered. These professional apps are not suitable for regular daily web surfing.
How to block browser fingerprinting
The Chromium - based Brave Protected Browser blocks tracking trackers that collect digital fingerprints.
Blocking fingerprinting in the Brave browser
Its default settings are set to standard blocking of fingerprinting. Strong blocking that stops any browser fingerprint recognition activity, but it can disrupt sites.
There are versions of Brave Private Browser for Windows (32/64 bit), Mac OS and mobile browsers for Android and iOS.
Canvas fingerprinting method
Canvas is an HTML5 tag for creating images or animations using scripts (mostly in Java). Each computer renders these images differently, due to the unique combination of browser, operating system, and video card model. Canvas fingerprinting assigns a one-of-a-kind identification code to a PC that is virtually never repeated.
Mozilla Firefox notifies the user if a site requests permission to use HTML5 Canvas, warning that this can be used to generate a digital fingerprint.
Change the fingerprint of a browser
To change the fingerprint of a browser, it is enough just to change one of its components. The simplest option is to change UserAgent. Perhaps the only difficulty is that you are working with CEF.
CefSharp has such a thing as CefSettings. And she, in turn, has the CefSettings.UserAgent field. I think it's clear which direction I'm leaning in. Sample code from English SO:
Code:
public Form1()
{
InitializeComponent();
CefSettings cfsettings=new CefSettings();
cfsettings.UserAgent = "My/Custom/User-Agent-AndStuff";
Cef.Initialize(cfsettings);
chromiumBrowser = new CefSharp.WinForms.ChromiumWebBrowser("http://whatsmyuseragent.com/")
{
Dock = DockStyle.Fill,
};
this.Controls.Add(chromiumBrowser);
}
