Test Your Online Privacy Protection with EFF's Panopticlick
December 19, 2015The Electronic Frontier Foundation (EFF) launched new online tracker-testing in its Panopticlick tool today, helping you analyze the privacy protections in your Web browser.
When you visit a website, online trackers and the site itself may be able to identify you, and the records of your online activity can then be distributed among a vast network of advertising exchanges, data brokers, and tracking companies. Many people install ad- or tracker-blockers to try to protect themselves, but it can be hard to know how effective they are. Panopticlick will check your browser and your add-ons and assess the privacy protections users have in place. It can also suggest remedies for under-protected browsers.
But even if you have strong tracker blocking installed on your computer, you could still be identified by whats called a "browser fingerprint." Thats the combination of factors such as your operating system, your browser, and plug-ins. Panopticlick also analyzes the uniqueness of your browser to see if you are still at risk from this kind of data-gathering, even if you have privacy-protective software installed.
"Have you ever felt like ads you see online have an uncanny knowledge of your browsing habits? Its creepy, and a sign you are being tracked," said EFF Chief Computer Scientist Peter Eckersley. "When you visit Panopticlick and click on the \'test me' button, the site simulates the loading of various tracking technologies. Then you get a report to help you understand what protections you have in place, and what's missing. Panopticlick is a great way to boost your privacy as you read, shop, and interact with websites throughout your day."
Fighting for user privacy on the Web can feel like an uphill battle, with advertisers and marketers changing their tactics and technologies at a lightning pace. Panopticlick will also do double-duty as a research project for EFF, collecting anonymous data for technologists to analyze so they can improve privacy tools like EFFs Privacy Badger and develop others down the road.
"Online data-gatherers use tactics that are complex, subtle, and ever-evolving," said EFF Software Engineer Bill Budington. "Panopticlick is a way for you to help protect yourself, as well as help contribute to our understanding of online tracking more generally."
