Why Replace Fingerprint?

Fingerprint obfuscation may be required for the following tasks:

  • To stay anonymous online. It allows you to protect your data from systems that collect user data to identify them.
  • To imitate regular user data. Do not confuse user anonymity with user imitation. In the former case, the software obfuscates your real data. In the latter case, it replaces your data so that you do not stand out among millions of regular users and do not create anti-fraud systems’ awareness. For this, the fingerprint must not be unique, but similar to other fingerprints. The latter is more challenging. 
  • To manage dozens of accounts on a single website. It might be required, for example, for betting, social networks, ad launching, etc. 
  • To view locked resources.
  • To test the interface. It might be required if you need to test the website in different countries.

What Do Various Fingerprint Parameters Mean? 🤔

Each parameter is important to generate the overall fingerprint of the browser and the system. Let’s examine them.

Useragent

Useragent is a browser program item. If you use several browsers on a single device, they will have a slightly different useragent. Useragent data include, for example, browser name and version, language, device type, OS type, and version, etc.

Useragent allows to:

  • View the correct data of a specific resource.
  • Learn your device and browser data to identify you online.

IP

It is one of the basic parameters that even primitive anti-fraud systems can analyze. IP allows anti-fraud systems to obtain information about your location and ISP to exchange data between the device and servers. To change the IP address and imitate a regular user, opt for high-quality proxies

Top anti-detect browsers support any proxy. Here’s how you can add a proxy to Dolphin{anty}:

Прокси

Canvas

Canvas is an HTML5 element that creates and determines the area for an image. This element displays various diagrams, animations, games, graphics, etc.

Canvas is not a unique parameter and may be the same for several users. Therefore, if you require it to imitate the fingerprint of a regular user, browser developers commonly recommend leaving it by default.

Canvas

WebRTC

It is a special plugin that supports video and audio transmission on a web page. To speed up the loading, this plugin provides web resources access to your media devices like headphones or a camera. This parameter discloses your real IP address, even if you use a proxy.

In Dolphin{anty}, you can select one of the following options: disable WebRTC, replace it, show the real one, or configure it manually.

WebRTC

You might want to check with the anti-detect browser developer which WebRTC option to select depending on your objective.

WebGL

It’s a JavaScript web library that allows access to a video display board to create 2D and 3D graphics. WebGL works with Canvas. 

Apart from various graphics operations, WebGL significantly speeds up the web page’s down speed because it doesn’t require third-party plugins.

According to the data available, various websites use WebGL data to obtain your device’s fingerprints beyond encryption. To protect this data, anti-detect browsers offer three options to choose from:

  • Leave WebGL by default;
  • Disable WebGL;
  • Add noise.

If you are using an anti-detect browser, check with the browser developer which option is better for your tasks: disable WebGL, leave by default, or add noise. As a rule, they recommend adding the noise if you require a unique fingerprint and disabling it in case you are sure that the anti-fraud system of a particular website is suspicious of a unique fingerprint.

WebGL

Time Zone

This data reveals your time zone. When selecting a time zone, ensure that it matches your IP address. Otherwise, anti-fraud systems will quickly detect that you are obfuscating your real data.

timezone

Language

As with the time zone, you might want to select the language according to your IP and location. It is also important if you work with social accounts. In this case, the browser language must match the account language.

Geolocation

You might think that websites obtain this data from an IP, but the data may also be collected via the API. This is because users may change their IP, for example, in case they switch to another ISP or restart their device. 

As with other parameters in Dolphin{anty}, you can change geolocation manually or automate it.

Геолокация

CPU

In Dolphin{anty}, you can select one of the following GPU parameters: 2, 4, 6, 8, 12, or 16.

Процессор

Memory

This parameter reveals the RAM of the device. As of this writing, you can specify 2, 4, or 8 GB or an automated selection.

Memory

Screen

This parameter reveals the screen density. You can opt for automatic selection or configure this parameter manually.

Разрешение экрана

Media Devices

This parameter includes data on the number of microphones, speakers, and cameras on your device or the ones connected to your device. In Dolphin{anty}, you can select up to three parameters.

Медиа

Ports

These are network ports used for data exchange and transmission. Imagine a port as the place where specific applications intercommunicate. 

There are two key port protocols:

  • TCP is a transport protocol that provides continuous data exchange between two devices. 
  • UDP protocol provides a quick connection. 

For example, 3389 is a Microsoft Terminal Server (RDP) port, and 5938 is the UDP/TCP protocol of the TeamViewer.

How to Ensure Anti-Detect Browser Security? 🔍

To assess the quality of obfuscation, some users verify the quality of the anti-detect browser with digital fingerprint scanners. Learn more about these services in our compilation here.

However, it is important to consider the following:

  • The data the scanner provides is for informational purposes only. This means that you can use it as the verification step, but you might not want to rely on it solely. Besides, given that each scanner verifies a different data volume with its built-in algorithms, sometimes it may occur that while one scanner won’t detect the fact of obfuscation, the other one will. 
  • Each website has its algorithms to verify user data. Because of this, some firewalls might detect some particular parameter, while others might ignore it. If you have previously used different anti-detect browsers, you may have noticed that, given large volumes, some browsers can work well with Facebook, while others may be better for cryptocurrencies or search engines. 

For obvious reasons, websites keep user verification criteria and algorithms out of the public exposure, so the best way to learn how a particular website checks you is to gain experience and study others’ best practices. For example, users exchange some ideas in the  Dolphin{anty} telegram chat.

What to Consider When Selecting an Anti-Detect Browser? 🧐

We have compiled some basic parameters that you might want to consider when selecting an anti-detect browser:

🔸Obfuscation quality, quantity, and type

For example, some anti-detect browsers support a feature that allows simulating a mobile connection. However, due to considerable differences in smartphone and PC settings, websites always identify the device the user logs in with. That is why you might not want to simulate the mobile connection from a PC.

🔸Frequency and rate of browser updates

All anti-detect browsers are powered by some top browsers like Chrome, Chromium, or Firefox. When viewing websites, security systems identify the user’s browser version. If the browser version is too outdated, anti-fraud systems may suspect that something is wrong with the user. Case in point: Chromium’s current version is 101 but the user logs in from version 80. 

To avoid such problems, the anti-detect browser must release updates to the current version of the browser it is powered by quickly. As a rule, developers report updates on their website or the news channels dedicated to the product.

🔸How well the anti-detect browser handles bugs and failures

As with any software, anti-detect browsers have malfunctions. There are two types of browser malfunctions: 

  • Local, when a few users, for example, from a certain city have trouble. 
  • Mass scale, when many users have trouble, for example, due to a large-scale malfunction of browser servers.

When selecting an anti-detect browser, take time to study the reviews, chat rooms in social networks or telegram, if there are any, etc.

Pay attention to the company’s responses to user requests and negative feedback. Check whether they delete comments or respond to criticism with reason and help users to find the solution.

For example, in 2022, many services and companies in the Russian Federation faced problems because of regular failures and restrictions imposed on specific servers’ connections.

It is important to realize that by failures we mean problems with the browser. Often, failures may arise due to the user actions like selecting incorrect proxies, ISP failures, etc. To name a few, we’ve analyzed common mistakes publishers make when working with anti-detect browsers.

Advanced Features

There are no distinct criteria here because users require various parameters. For instance, some companies may require that the browser supports teamwork and token distribution. Other users would rather appreciate the user-friendly interface. 

We’ve compiled the basic parameters which affect how anti-fraud systems identify that the user is replacing their digital fingerprints in this article.
