Recently, users have become more vigilant in purging cookies from their computers. According to a Jupiter Research study, 58% of online users have deleted cookies from their computer and 39% of users do so on a monthly basis.

One of those methods is to set a “Local Shared Object,” also known as a “Flash cookie” to track individuals. Simply put, the idea behind this tracking is to set two cookies on the user’s machine–a standard cookie that the consumer may erase, and a second Flash cookie that the user probably will keep, because the existence of Flash cookies is not well known….
