According to Jupiter Research, 58% of web surfers deleted cookies from their system in 2004. This has sent a loud message to marketers in regard to consumer's preference as to tracking their online activities. The marketers have responded with PIE. Persistent Identification Element (PIE) is a technology that uses Macromedia's Flash MX to track you even without using cookies. Macromedia has created a page to instruct users on how to disable this.
Real sneaky. Using PIE to track browsing behavior instead of cookies! I just checked my Macromedia settings and discovered that only flickr is storing information on my browser. You can find out which other sites are storing flash information by checking your website privacy settings or website storage settings. I'm switching off all settings, aside from flickr. Let's see what sites it breaks. :)
