Google has regularly been in the firing line on privacy issues. Campaigners have criticized it for the way it stores and uses individuals' information. Concerns have also been raised over Google Health, a hosted service launched last month which allows users to store and manage information regarding their health online. Critics say there is a risk individuals' medical information could end up in the wrong hands.
Fourteen privacy groups have signed the letter to Schmidt, which was published by the PRC yesterday. They are all organizations from California and Washington DC and include the Center for Financial Privacy and Human Rights, the Electronic Frontier Foundation, the Electronic Privacy Information Center and the World Privacy Forum.
Marc Rotenberg, executive director of the Electronic Privacy Information Center said: "This is not rocket science. The word 'privacy' is not going to take up a lot of space on the Google homepage."
The letter to Schmidt claimed its reluctance to act was "alarming."
Google could offer no comment at the time of writing.
