Web device fingerprinting is a method of identifying devices by collecting different attributes and characteristics—such as the operating system, browser version, screen resolution, plugins, and language settings—to create a digital fingerprint that can be used to identify and distinguish one device from another. When combined with behavioral analytics and other fraud prevention strategies, this approach can help reduce the chances of fraudulent behavior and increase the effectiveness of authentication protocols, especially when it comes to phishing and bot attacks.
Identifying Unique Devices
Browser fingerprinting is a powerful tool that helps businesses recognize returning users and adapt features based on their history. It can be used for digital advertising purposes, as well as for ecommerce and payment systems to provide personalized shopping experiences. However, it is important to note that fingerprinting can also lead to user identification. This raises privacy concerns and can open up the door for bad actors to abuse this data.
Using Device Fingerprinting in a GDPR-Compliant Manner
To ensure that fingerprinting is conducted in a GDPR-compliant manner, it is critical to establish a legal basis and to provide clear information and options for user control. Additionally, it is vital to ensure that all data collected through fingerprinting is hashed and aggregated in a way that makes it resistant to reverse engineering. In addition, it is important to avoid relying solely on fingerprinting for authentication as this can lead to false positives, which may prompt fraudsters to try even more sophisticated tactics.
