> The Privacy Foundation has just released an advisory

> allow the author of a document to track via the Internet
> where a document is being read.  The trick could be used
> to monitor leaks of confidential documents from a
> organization to outsiders as well as detecting
> copyright violations.  In addition, it is also
> possible to place Web bugs in individual paragraphs
> and detect when the text is copied from one Word
> document to another.
