In recent years the battle between user identification systems and privacy protection tools has intensified. Websites, advertising platforms and other services strive to accurately determine who is using them in order to combat fraud.
One of the key methods of user identification has become digital fingerprint analysis. Unlike cookies, such a fingerprint is difficult to hide. That is the main reason why antifraud systems actively analyze it to detect multiple registrations, bots and other suspicious activity.
In response to this level of monitoring, solutions have emerged that allow users to maintain their anonymity. And this is no longer just about proxies or VPNs, but specialized software. This raises the question: who will win in this ongoing battle? Let’s find out.
Browser fingerprint analysis is a method of identifying users based on a combination of parameters from their device and software environment. Instead of storing data on the user’s side, as cookies do, the system collects the technical characteristics of the browser and device and creates a unique profile.
When visiting a website, the browser automatically transmits a large amount of data. Some of this data is considered key and is most often used in forming a digital fingerprint:
Browser identifier is a string containing information about the browser type, its version and the operating system.
Operating system indicates whether the user is on Windows, macOS, Linux, Android or another platform.
Screen resolution includes the screen dimensions and sometimes scaling settings.
Time zone helps determine the user’s region and correlate it with other parameters.
Font set is the list of fonts installed on a system. It can vary significantly across devices.
Graphics processing includes characteristics of the graphics interface and video card that provide additional distinguishing features.
Hardware specifications are formed by the number of CPU cores, amount of RAM and other device parameters.
Even if each of these parameters separately is common among millions of users, their combination is often unique enough. This results in a digital profile that can reliably distinguish one user from another.
At the same time, the parameters listed above represent only a basic level of analysis. Modern systems can take into account dozens or even hundreds of additional characteristics: graphics rendering details, browser behavior when executing scripts, audio system parameters and other minor technical specifics.
The depth of such analysis largely depends on a company’s resources. Large tech platforms like Meta or Google can afford to invest significant funds into developing antifraud algorithms and digital fingerprint analysis.
For smaller services, such systems are often too expensive and complex, so they rely on simpler user identification methods.
The technology of browser fingerprint analysis did not emerge merely as a tool for tracking users. For many online services it has become an important part of security and account management systems. Understanding the device and environment of a user helps these services detect suspicious activity more quickly.
The main reason to use these technologies is to combat fraud. Digital fingerprints help identify duplicate registrations, attempts to create multiple accounts and other malicious activity. According to a report by Kasada, 98% of organizations have experienced revenue losses due to fraud.
Platforms aim to limit multiaccounting because it can distort service operations and create additional risks. Multiple accounts are often used to bypass restrictions, manipulate ratings, inflate activity or regain access after bans. Additionally, mass account creation increases the load on moderation systems and complicates fraud prevention, so many services strive to detect and consolidate such accounts.
On the other hand, fingerprint analysis also helps protect individual accounts. For example, if a user usually logs in from one device but suddenly appears to log in from a completely different set of parameters, the system can prompt for additional verification or temporarily restrict access. This approach is widely used to secure accounts and prevent hacks.
Another key application is banning bots. Automated programs often operate in identical environments and leave similar technical traces. Digital fingerprint analysis allows platforms to detect such patterns and block mass automated activity.

However, security is not the only reason this technology is used. Digital fingerprint analysis also helps services gain a better understanding of user behavior. Advertising platforms leverage this data for analytics, targeted advertising and measuring the effectiveness of campaigns. Content platforms can use it to personalize interfaces and recommendations.
Different types of online platforms apply these technologies in their own ways. Ad networks focus more on analytics and targeting as their revenue and reputation depend on the uniqueness of their users. According to WiFi Talents, losses from ad fraud could reach $172 billion by 2028. Giants like Google and Meta certainly cannot afford to lose money in their core business.
Therefore, tracking users via fingerprints is not merely a monitoring tool. In many cases, it has become an integral part of modern internet infrastructure, supporting service functionality, account security and the stability of online platforms.
Multiaccounting is often perceived by platforms solely as an attempt to bypass rules, but in practice it is also used for entirely legitimate purposes. For example, advertising specialists run campaigns for multiple clients and manage several ad accounts. In SMM managers handle dozens of brand and project pages. A similar situation exists in HR, where recruiters may manage multiple accounts on professional platforms.
Moreover, many professionals use multiple accounts to minimize risk. On some platforms account suspension raids occur on a regular basis and are not always accompanied by detailed explanations. For instance, in 2025, Facebook removed over 10 million accounts. Inevitably, some users lost access to their profiles even though they had done nothing illegal.
In such conditions distributing tasks across multiple accounts becomes a way to protect workflows and prevent complete work stoppages.
This is where antidetect browsers come into play. They allow the creation of isolated browser profiles. And each of them appears to a website as a separate device with a unique digital fingerprint. Let’s take a closer look at how this technology is implemented using Dolphin Anty as an example.
The foundation of any antidetect browser is a system of isolated profiles. Each profile operates as a separate environment and appears as an independent device. It has its own set of parameters, its own data storage, separate cookies and browsing history. This allows multiple accounts to be used in parallel without creating overlaps between them.
In Dolphin Anty, data from different accounts does not mix. This reduces the likelihood that tracking systems will be able to link multiple accounts to each other.
To create a unique digital fingerprint, antidetect browsers modify or spoof various technical parameters of the browser and device like:
Canvas — a graphics rendering technology that is often used to obtain unique characteristics of a system.
WebGL — a graphics interface that can reveal details about the video card and its drivers.
Audio — sound processing parameters that may differ from one device to another.
Hardware characteristics — such as information about the CPU, memory and other components.
In total, Dolphin Anty offers more than 50 parameters for fingerprint configuration, each accompanied by a brief explanation. Some of them are quite unique for this type of software, for example, device name. When dealing with powerful platforms that analyze even the smallest details, such parameters can sometimes play a decisive role in whether an account gets flagged or blocked.
Modern antifraud systems analyze not only individual device parameters but also their logical consistency. For example, the browser version must correspond to the operating system and the characteristics of the graphics card must match the type of device. If the parameters look like a random collection of data, the system can quickly determine that such a fingerprint does not resemble a real device.
That is why modern antidetect browsers do not simply randomize technical characteristics. Instead, they generate profiles based on real combinations of devices, operating systems and browser versions. This approach makes it possible to create a more believable digital fingerprint that appears natural to tracking systems.
In Dolphin Anty only real device configurations are used when creating a profile. As a result, the parameters of the browser, operating system and hardware characteristics appear consistent and match the types of devices that real users typically operate. This reduces the likelihood that an antifraud system will detect the artificial origin of the digital fingerprint.
A browser’s digital fingerprint is rarely used in isolation. Most platforms analyze it together with network parameters, primarily the IP address. If multiple accounts use the same address even different browser fingerprints may raise suspicion among security algorithms.
Therefore, creating a complete digital identity requires a combination of two factors: device parameters and the network environment. When each account operates not only with a unique browser fingerprint but also with a separate IP address, the platform perceives it as an independent user connecting from a different device and network.
That is why antidetect browsers include tools for proxy management. In Dolphin Anty proxies can be directly assigned to individual profiles. This allows each profile to use its own IP address and network configuration, ensuring that accounts remain isolated from one another and do not overlap in tracking systems.
To make things easier for users, there are also integrated providers with free traffic. Connecting them only takes a couple of clicks: just select the provider and activate it.
In addition to spoofing digital fingerprints, antidetect browsers solve another important task: they are developed for convenient management of large numbers of accounts. When the number of profiles reaches dozens or even hundreds, working without dedicated tools quickly turns into chaos. That is why solutions like Dolphin Anty offer builtin systems for organization and automation.
One of the basic tools includes statuses, tags and notes. These help structure profiles and quickly understand their current state. For example, accounts can be marked as active, under review or blocked, tagged by project or region and supplemented with notes containing important information about each profile.
Bulk actions are used to speed up workflows. Instead of configuring each profile individually, users can apply changes to a group of profiles at once, for example, launching them simultaneously, changing proxies or updating settings.
Another important organizational feature is profile folders. They allow accounts to be separated by platforms, clients or projects. This approach is especially useful for teams and professionals who work with multiple services at the same time.
Finally, automation plays a significant role. In Dolphin Anty several tools are available for this purpose: scenarios for performing repetitive actions, a synchronizer for working across multiple profiles simultaneously and a cookie robot that helps automatically manage cookie files. These features significantly speed up routine tasks and simplify the management of large numbers of accounts.
Digital fingerprinting technologies continue to evolve and today many platforms are increasingly relying on artificial intelligence tools. Modern antifraud systems are no longer limited to checking individual device parameters. Instead, they analyze large volumes of data and attempt to detect complex relationships between user actions.
One of the key directions is behavioral analytics. Systems track not only device characteristics but also how a user interacts with a website: typing speed, mouse movements and the sequence of actions within the interface. This type of analysis helps distinguish real users from automated scripts and bots.
Another important tool is the device graph. Platforms build complex models that map relationships between accounts, devices and networks. If several accounts regularly use similar parameters, connect through similar networks or interact with each other, the system may group them together and identify potential links between them.
Network analysis is also widely used. Platforms monitor which networks users log in from, how frequently IP addresses change and how those addresses are related to each other. This helps detect abnormal activity patterns and uncover infrastructure used for large‑scale account management.
All of these methods are strengthened by machine learning algorithms capable of identifying patterns within massive datasets. Over time such systems are becoming more accurate and increasingly effective at recognizing unusual behavior.
Despite this, it is still too early to say that fingerprint spoofing is losing its effectiveness. The technology is not disappearing. It is rather evolving alongside antifraud systems. This means that the ongoing confrontation between tracking and anonymity is likely to continue.
