If a company that doesn’t intend to track its users becomes blocked anyway, it can adopt a legally-binding Do Not Track (DNT) policy that commits the company to respecting users’ privacy. When new trackers appear on the web, or formerly benign companies start tracking users, Privacy Badger learns to block them without any help from us. ![]() ![]() Then we let the extension decide on each request it sees for us. We try to define what tracking behavior looks like, so that any third-party domain that acts that way is likely to be a tracker, and any one that doesn’t is likely to be benign. Privacy Badger takes a different approach. Creating a list like that requires tens of thousands of judgment calls by human beings, and maintaining it means making those decisions over and over again, for as long as the list is in use. EasyPrivacy, the popular tracker list used by AdBlock Plus and others, has almost 17,000 entries. The idea is to keep a list of every single domain or URL that might be tracking you on the web. List-based blockers have humans make those decisions on a case-by-case basis. Is a content delivery network (CDN) that serves static files across the web a tracker? What about a third-party image host? How do you decide what to block, and what to allow? But other times, it’s not so straightforward. When an ad network sets a third-party cookie and uses it to build a profile of your browsing history, it’s tracking you. Install Privacy Badger What makes a tracker a tracker?Īll tracker-blockers have to grapple with a fundamental question: what is a tracker, anyway? Often times, it’s obvious. Last week, we updated Privacy Badger with a new heuristic to help it identify trackers that have flown under its radar in the past. It works using heuristics, or patterns of behavior, to identify trackers. Rather than rely on a list of known trackers, it discovers and learns to block new trackers in the wild. Most blocking tools, like uBlock Origin, Ghostery, and Firefox’s native blocking mode (using Disconect’s block lists), use human-curated lists to decide whether to block or allow third-party resources. Mobile users have much less of a choice when it comes to anti-tracking extensions, as Disconnect and Privacy Badger are compatible with desktop systems only.The latest release of Privacy Badger gives it the power to detect and block a new class of evasive, pervasive third-party trackers, including Google Analytics. The EFF’s Privacy Badger is also a good alternative, although it is still in the early stages of development and so may contain vulnerabilities and flaws. In the past we have always recommended the open source anti-tracking extension Disconnect over Ghostery, and this recommendation stands (although even more so now). ![]() In fairness to Evidon, it is completely open and transparent about its business model, the Ghostrank feature is entirely opt-in (disabled by default), and all information collected from volunteers is completely anonymous. ‘Several of these extensions have business models that we weren't entirely comfortable with.’ We have a feeling that the Electronic Frontier Foundation (EFF) had business practices such as this in mind when it developed its own anti-tracking extension Privacy Badger, and in its FAQ when asked ‘How is Privacy Badger different to Disconnect, Adblock Plus, Ghostery, and other blocking extensions?’, it answered, ‘ We’ve got a really nice business model.’ In other words, the company we trust to protect us from advertisers, profits from helping those same advertisers! Many are likely to feel uncomfortable about that.Īs a way to make money this has proven highly successful, as Evidon CEO Scott Meyer boasted in an interview with VentureBeat, In order to combat this tracking, a number of browser extensions have been developed, and, with around 20 million users, Ghostery is among the most popular of them. Tracking internet users as they surf the web is an affront to personal privacy, but is so useful as an advertising tool that it has become almost ubiquitous. ![]()
