A new study released Tuesday by Stanford has found your privacy on the Internet may not be as secure as you think.

A study by Jonathan Mayer at Stanford's Center For Internet and Society found that major retailers often hand your email address to dozens of companies. Some web sites will even pass on your full name.

Often your user name is tracked by third party companies following your online activities.

Tuesday Consumer Watchdog called on federal regulators to investigate whether companies are violating their privacy obligation to consumers.
