Following a nine-month investigation into Google's data collection practices, European authorities have ordered the firm to change its methods of gathering personal information if it wishes to avoid "high risks to the privacy of users".
In a letter signed by 24 of the EU's 27 data regulators, a total of twelve recommendations were mentioned. French data regulator CNIL were asked by the EU to carry out the lengthy investigation on behalf of the other countries within the EU.
During March, Google changed its policies by combining data from its pool of services and sites such as YouTube and Gmail in a move targeted towards more effective advertising. The move resulted in 60 individual privacy policies for Google-owned sites merging into a single policy.
Google has stressed that the policy complies with EU law, but regulators raised concerns about the policy change before and after it was implemented several months ago.
If it fails to adhere to the request to amend its way of gathering personal information, Google will face penalties, regulators warned.
