Browser fingerprinting is the backbone of many major fraud detection solutions. Fingerprinting can identify unique visitors and associate sessions through incognito browsing, VPNs, cookie blockers and other technologies used to anonymize fraudulent actors online. The technology works by analyzing data passed by the visitor's browser, device, patterns of use and more to generate a unique fingerprint, which can be used to associate patterns of fraud.
In addition to browser fingerprinting, FingerprintJS Pro's server-side API processes and analyzes vast amounts of data, searching for patterns and re-occurrences of fraudulent activity, and associates fingerprints that are likely the same user together under the visitorID identifier.
