Description: Device fingerprinting is a technique used to identify a device based on its unique characteristics. Each device, whether a computer, smartphone, or tablet, presents a set of attributes that make it distinctive, such as the IP address, operating system, browser configuration, and other technical parameters. This information is collected and used to create a profile that can be employed in authentication and security processes. Device fingerprinting becomes a valuable tool in the realm of multifactor authentication, as it allows for verifying the user’s identity not only through passwords or biometrics but also by identifying the device from which a service is accessed. This adds an extra layer of security, making unauthorized access more difficult, as an attacker would need not only the user’s credentials but also the specific device that has been previously authenticated. Therefore, device fingerprinting is an essential component in the fight against fraud and unauthorized access, contributing to a safer digital environment.
