How to Prevent Fraud with Device Fingerprinting

Cyber fraudsters keep pace with progress and regularly invent new ways to deceive merchants and their clients. In response, modern services release reliable methods for analyzing potential buyers and fighting scammers. Recently, device fingerprinting protection has proven its reliability, which helps identify shady visitors at an early stage. Read below to understand what it is and how exactly it can help your business.


Device fingerprinting is a unique technology that allows you to collect and analyze data from a smartphone, tablet, computer, or laptop of a visitor to your site. This information includes both hardware and software features (there can be several hundred parameters in total). Based on it, you can conclude the reliability of a client and take appropriate measures if they turn out to be fraudsters. In general terms, this method resembles the collection of cookies familiar to many users; it is just more detailed and durable.


This technology can be used to fight fraudsters who seek to steal your customers’ accounts or their bank card details. Of course, scammers try to hide their identities from various detection systems, but doing so is what betrays their intentions. Device fingerprinting responds to triggers such as:

  • Incognito mode in a browser;
  • Frequent change of browsers;
  • Applying emulators and plugins;
  • Using outdated versions of OSs and browsers;
  • Application of anti-detect tools.

Although the purpose of using such methods is to hide device data, it is ultimately the combination of these means that makes a smartphone or computer unique to advanced fraud detection systems.

The key characteristics of fingerprinting are stability and diversity, which means that all devices are different from each other, and their content (both software and hardware) will never change. However, it is not always true, and a device fingerprint can be changed if necessary. 

It is crucial to choose the solution that can accurately determine whether hashes belong to the same smartphone, even if only one of the components is different or if they are still various devices. Modern services offer cross-browser versions of their security tools in combination with other anti-fraud methods to avoid possible inaccuracies.

Operating Principle

The principle of operation is quite clear, straightforward, and if you have connected the appropriate service, it is completely automated. To monitor the actions of visitors to your website or online store, you can embed a special script on the page you need. This tool collects the information necessary for identifying users and combines it into a single set, which is a fingerprint (in other words, hash).

If you use this method in combination with other recognition instruments, the accuracy of the result is higher. Based on the received data, a system can make a conclusion about the reliability of a particular client. Of course, incognito mode, VPN servers, and different browsers are not prohibited, and regular clients can also use them. However, the combination of several triggers and especially the numerous payment errors should make you wonder about the legitimacy of a visitor. You can simply block a specific transaction or study the user in more detail.

Opt for Use Multi-Layered Solutions

Device fingerprinting allows businesses to determine if a request comes from a trusted source or if a client uses a device that has previously been seen engaging in suspicious activity. Like many other fraud prevention and anti-scammers methods, it has its pros and cons. To minimize the negative consequences of these shortcomings, experts advise using several reliable tools at once. Multi-layered solutions can help you stay ahead of fraudsters while remaining flexible to work comfortably with trusted customers.
