What is?

Benefits

Device & Browser Fingerprint is an essential
module within Fraud Prevention, responsible for
identifying the "digital fingerprint" of the devices
used by users when connecting to a system. This
process involves the collection of technical data anddevice properties in order to prevent online identity
theft and electronic fraud.

The ability to quickly identify and block a device
used in fraudulent activities significantly reduces thelikelihood of fake accounts being created or
fraudulent transactions being carried out. Our tool
uses data such as the device model, brand, andoperating system to alert and prevent theft of digital
accounts before any illegal activity can take place byunauthorized devices.

Device & Browser Fingerprint compares the "digital
fingerprints" of devices that attempt to connect tothe system with the devices associated withlegitimate users of the service. It then calculates thesimilarity and executes the previously configured
access and blocking rules accordingly in each case.

Establish rules for transactions to classify thembased on their risk potential
Recognizes user, device, and account trust, evenin private browsing
Detects and blocks fraudulent attacks before they
impact reputation or business profits
Prevents scams throughout the user experience,
including phishing and fraudulent purchases
Identifies mule accounts using blacklists that
include accounts suspected of being used forfraudulent purposes
Can be implemented as part of an integrated
solution or as a standalone module thatintegrates with any existing application orsystem.

Outstanding use cases
Workforce, customer, and contractor management
Online payment methods, direct deposits, and e-wallet traffic
User enrollment and login verification
Remote acquisition of digital tickets, travel packages, or services.

Device validation process
Device & Browser Fingerprint retrieves the device's fingerprint from which the user intends to connect tothe system
It compares this information with the known devices for that user and executes the previously configured
rulesIf the obtained similarity percentage matches the predefined authentication parameters, the user is allowed
access to the system
If the similarity percentage does not reach the minimum threshold, the actions defined by the rules areapplied. 

Positive authentication:
