Device fingerprinting is a great way to avert online fraud. It enables marketers to identify users and track their activities across websites. This information is stored on the merchant’s server. It’s also useful for preventing ad fraud.
How does device fingerprint help in protecting private information?
While device fingerprint isn’t completely foolproof, it’s the first step to protecting your online privacy. Using this technology to detect fraudulent activity will help you identify suspicious payments.
In addition, it can give you a clearer picture of your customer’s behaviour. If you’re dealing with ad fraud, this information could allow you to retarget ads to the right customers.
A device fingerprint is a unique hash for a particular user’s device. It can be found by tracking an individual’s activities on a website or through intercepted Web banking sessions.
While a fingerprint isn’t exactly the most accurate way to track a device’s usage, it can be a good indicator of what sites a particular person has visited. By using a nifty little JavaScript pixel, a web browser can collect a few data points.
The most important thing to remember is that a device fingerprint is only as good as the information gathered by the device. That means you’ll need a good data storage system. You can even link to other fingerprints to improve your unique identifier.
The most common device fingerprinting solutions will require you to store the information in a database. The data can then be used to build a detailed profile about a user. These profiling tools are available from the largest data brokers.
