As fraudsters and bad actors develop increasingly sophisticated methods to steal money and data, businesses must deploy advanced technologies to detect their attempts. Device fingerprinting documentation is a powerful tool that works by gathering a range of attributes from a user’s device and browser. This information is then used to identify the device and create a unique identifier that can be used to prevent fraud, identify high-risk behavior, and improve the customer experience.
To gather this information, the device and browser must be scanned in order to collect an array of data points. These data points can include hardware information (like screen resolution, CPU type, and installed fonts), software information (like operating system version and browser type), network-related information (like IP address), and even behavioral patterns (like mouse movements and typing rhythm). The collected data is then analyzed to create the device fingerprint. Once the fingerprint is established, it can be compared to previous device fingerprints to detect unusual or suspicious activity.

While this technique is effective, several factors can impact its reliability. For example, users can modify or hide some of the attributes gathered by device fingerprinting, which can impact the accuracy of the detection process. Additionally, the dynamic nature of devices means that they can change over time, with updates to operating systems or hardware affecting the characteristics used to fingerprint them.
The use of device fingerprinting can also raise concerns over privacy, and it’s important for businesses to communicate clearly with their customers about what they are doing with the information gathered. This is particularly important as GDPR makes it harder for companies to use cookies and other tracking methods for personalization.…
