Can a cookie identify a user to a Web site even if that user has never submitted personal
information to that site?

A.
Yes – if the user visited a site that uses shared cookies, the user can be identified using data
that was passed to another site.

B.
No – commercial sites do not share customer data with other sites; they encrypt cookie
information to prevent this.

C.
No – passing this information constitutes an extreme security risk, and no site would jeopardize
its uses that way.

D.
It depends on the type of information authorized by the user, which is defined in the User Profile
section of the browser administration screen.
