Demo on Privacy Issues with Javascript
This page provides an example on how Javascript can be dangerous.
To view this demo, please turn the Javascript setting of your browser
to "enable Javascript".
We use a very simple mechanism--"onMouseOver" in the html
<a> tag---to
invoke some Javascript code to open a new connection.
Please
move the mouse over me.
You will see a new browser window coming up
that takes you to the server www1.idzap.com,
which is a different site from the one that you are using now.
Of course the web site creater can call any URL as desired.
It is possible to open the new connection without popping up
a new window so that the user is not aware of what is going on.
It is also possible to create Javascript code so that
the new connection is made as soon as the currently page is loaded,
or as soon as you leave the page or close the browser!
The only way, that we are aware of, to overcome this problem is
by disabling Javascript.
So please be careful if you want to turn on Javascript,
especially when you are visiting some unknown web site
for the first time.
