Google has found itself under scutiny by a European Union panel, which is investigating whether the search engine falls within Europe's strict privacy rules. 

The panel has asked Google to respond to a number of questions about how it stores and retains users information for two years.
The Internet company will respond by the time the panel meets again at the end of June.
Google uses cookies to store information about what users searched and other information that could be sensitive. It has made no secret of its plans to use this kind of information to refine searches open up marketing opportunities.
Privacy advocates are concerned that there is potential to abuse this kind of information.
