Authorities in six European countries have taken steps to force US Internet giant Google to comply with EU privacy rules, France's Cnil data protection agency said on Tuesday.
In October last year the data protection agencies of the 27 EU states warned Google that its new confidentiality policy did not comply with European law and gave it four months to make changes or face legal action.
When that deadline expired in February several European data protection agencies set up a task force to pursue coordinated action against Google.
Cnil added it had notified Google that it had launched an inspection procedure.
It contends the move simplifies and unifies its policies across its various services such as Gmail, YouTube, the Android mobile system, social networks and Internet search.
But critics argue that the policy, which offers no ability to opt out aside from refraining from signing into Google services, gives the operator of the world's largest search engine unprecedented ability to monitor its users.
