Internet privacy and how to protect it is a growing concern for many users. In the past, these worries were focused on what we share intentionally: our identities, our personal details, the opinions we post in public forums. In recent years, however, the focus of concern has shifted. Web analytics have become more sophisticated and, as a result, targeted advertising has become incredibly specific.

Privacy advocates are worried about pervasive website tracking too, and they have their eye on the main culprit: cookies!

In this SlideShare, learn what cookies are, how to disable them, and how to keep them from coming back from the dead.

What’s going on here? How did they KNOW? If you’re a little creeped out about these eerily specific ads you’re not alone. Privacy advocates are worried about website tracking too, and they have their eye on the main culprit: cookies!
  3. 3. © 2016 eSOZO Computer & Network Services • Cookies go back to the early days of the World Wide Web. In 1994, developers at Netscape were trying to figure out how to make online shopping work. The website needed a way to “remember” who the customer was and what they wanted to buy. Thus, the web cookie was born. Cookies: Delicious or Evil? Without cookies, the internet as we know it simply would not function. There is nothing good or evil (or yummy) about them; they are just tools.

  5. 5. © 2016 eSOZO Computer & Network Services • Third-party cookies • Are set by a different webpage than the one you are visiting. • The sources are often advertisements or widgets. • Are used to track you across multiple websites and monitor your views, clicks, and anything else that might be relevant for marketing analysis. • The third-party cookie can spy on you from ANY website that displays an ad or widget from the same domain that set it in the first place. • This information is collected by the advertiser to construct a picture about who you are and what you like.

Mutant Cookies From Beyond the Grave?
  8. 8. © 2016 eSOZO Computer & Network Services • It works like this:  The third-party sets two standard cookies, plus one Flash cookie.  Every time you visit a webpage, the Flash cookie checks to make sure the standard cookies are present.  If it doesn’t find them (i.e. if you have deleted the cookies), it recreates them!  The outcome of this is a cookie that can’t be deleted; it keeps returning from “the dead,” again and again. Mutant Cookies From Beyond the Grave? The solution? Identify and delete the Flash cookie as well.
