Ghostery, Invisible Web, Security, Security best practice
There’s an invisible web that underlies everything we see. These things are invisible web – tags, web bugs, pixels and beacons that are included on web pages in order to get an idea of your online behavior. In other words, trackers. The debate rages on about the use of trackers by online advertisers and many people simply do not want to have their online activities tracked. But, what can one do about it?
I suggest that you check out Ghostery.com. They have a great little Firefox add-on that is free to download and use – plus you have their promise that Ghostery will never be used for advertising. The utility looks at the invisible web, tracks the trackers and gives you a roll-call of the ad networks, behavioral data providers, web publishers, and other companies interested in your activity. Here’s what they do next:
After showing you who’s tracking you, Ghostery also gives you a chance to learn more about each company it identifies. How they describe themselves, a link to their privacy policies, and a sampling of pages where we’ve found them are just a click away.
Then, it give you options so you can take whatever actions you want: block scripts from companies that you don’t trust, delete local shared objects, and even block images and iframes. That’s putting you pretty much back in control.
To be honest, I don’t much care about being tracked and marketed to in a targeted way by reputable companies; however, I do perform security research which sometimes leads me into the clandestine and dangerous areas of the web.
Ghostery currently tracks 486 web bugs & 338 cookies that you can block selectively, so I think that’s got a lot ground covered. But what’s really interesting about Ghostery is the information they give you on each company/method they have listed. Let me just take one example that I bet you don’t know about: Facebook Beacon. Here’s an excerpt from Facebook’s description:
Facebook Beacon is a way for you to bring actions you take online into Facebook. Beacon works by allowing affiliate websites to send stories about actions you take to Facebook. Here’s how that process happens: If you are logged in to Facebook and visit a Beacon Affiliate, an action you take (like writing a review or purchasing an item), may trigger that website to want to publish a story to Facebook.
Give Ghostery a test drive and see what you learn. I promise that it’s going to give me fodder for many articles about the Invisible Web, so stay tuned.
