Unlike traditional browser cookies, Flash cookies are relatively unknown to web users, and they are not controlled through the cookie privacy controls in a browser. That means even if a user thinks they have cleared their computer of tracking objects, they most likely have not. What’s even sneakier?Local shared object
Local shared objects ( LSOs ), commonly called flash cookies (due to their similarities with HTTP cookies ), are pieces of data that websites which use Adobe Flash may store on a user's computer. Local shared objects are used by all versions of Adobe Flash Player and version 6 and above of Macromedia's now-obsolete Flash Player. [ 1 ] While websites may use local shared objects for purposes such as storing user preferences, there have been privacy concerns regarding local shared objects, and they may be considered a breach of browser security . [ edit ] Storage Local shared objects contain data stored by individual websites.
From a recent UC Berkeley report: More than half of the internet’s top web sites use a little known capability of Adobe’s Flash plug-in to track users and store information about them, but only four of them mention the so-called Flash Cookies in their privacy policies. Under the direction of Chris Hoofnagle of the Information Privacy Programs at the Berkeley Center for Law and Technology, the researchers discovered that most web users aren’t familiar with Flash cookies and that Flash web cookies can’t be controlled through the cookie privacy controls in a browser. Even more interesting was the use of Flash cookies to ‘re-spawn’ or bring back to life traditional browser cookies that had been deleted on customer computers.
