There are restrictions to the data that apps and websites can get about your device. That’s partly because an app needs to know what type of phone you use so it can adapt to the processor speed and screen size. Similarly, when you install a mobile app, the operating system shares some information about your hardware with the app. That’s partly because a website needs to know things like the resolution of your screen so it can load a page in the correct window size. When you browse the web, your browser automatically gives websites some information about your hardware.

Fingerprinting takes advantage of a fundamental way that apps and websites talk to our devices. That thwarted traditional tracking methods like cookies and pixels that were embedded inside social media buttons.īecause many of those technologies became blocked by default, advertisers had to find a different way to track people. Tracker blocking is built into the Safari and Firefox browsers to make it harder for advertisers to follow us around the web and serve targeted ads. Over the last few years, tech companies like Apple and Mozilla introduced aggressive privacy protections inside their web browsers. As fingerprinting becomes more popular, here’s what you need to know about it and what we can do.

And an unknown number of mobile apps also use fingerprinting.Īll of this is not a reason to panic, but it is a reason to be concerned. Only about 3.5 percent of the most popular websites use it today for tracking, but that’s up from about 1.6 percent in 2016, according to Mozilla. Security researchers discovered fingerprinting as a tracking method about seven years ago, but it was rarely discussed until recently.

“That bar code is absolutely uniquely identifiable.” “Get enough of those attributes together and it creates essentially a bar code,” said Peter Dolanjski, a product lead for Mozilla’s Firefox web browser, who is studying fingerprinting. Once enough device characteristics are known, the theory goes, the data can be assembled into a profile that helps identify you the way a fingerprint would. What is it exactly? Fingerprinting involves looking at the many characteristics of your mobile device or computer, like the screen resolution, operating system and model, and triangulating this information to pinpoint and follow you as you browse the web and use apps. Even if we secure our data so we are not tracked online, the ad tech industry will find ways to monitor our digital activities.Īnd so it is with the rise of so-called fingerprinting, which security researchers are calling a next-generation tracking technology. If there’s one lesson to learn about digital privacy, it’s that we can never grow complacent.
