Flash cookies know where you’ve been

I had not heard of Flash cookies until Fernando Bermejo’s Berkman talk last week. Now he’s inaugurated his new blog (well, it’s his second post) with a posting about a new study. Fernando writes:

As for [end users], flash cookies are characterized as “super-cookies which are dramatically more resilient than cookies due to their implementation and a general lack of knowledge about their existence among consumer”.
