Do you blindly accept the cookies shown on a website?
Well, after reading today's post you might want to not do that.
In recent months, there has been a lot of fuss around the fact that Facebook tracks its users across the internet.
So how do they do this?
To remember that you’re logged in, Facebook stores a cookie on your computer, nothing unusual about that, many other sites do the same thing. This cookie is scoped, or bound to Facebook’s domain name, meaning that no one else besides facebook.com can read what’s in the cookie. Let’s now imagine that you browse away and you land on someone’s blog. The blog cannot read your Facebook cookie, and the scope prevents that. Facebook also can’t see that you’re on this blog. But let’s now assume that the owner of the blog places a Facebook like button on his website. To show this like button, your browser has to download some code from the Facebook servers, and when it’s talking to facebook.com, it sends along with the cookie that Facebook set earlier. Facebook now knows who you are and that you visited this blog. I’m using Facebook as the example here, but this technique is used by many other companies to track you around the internet. The trick is simple: convince as many websites as possible to place some of your code on their sites. Facebook has it easy because a lot of people want a like or share button on their website. Google also has an easy job because many websites rely on its advertisement network or on Google Analytics. At this stage, cookies are getting out of hand. However, the majority of cookies on these websites don’t serve the user. They are there to track you or to display more targeted ads. So what can we do to prevent these cookies from tracking us on the internet? As a user, you can protect yourself from trackers by installing a browser extension that blocks them like Privacy Badger or Ghostery.
