Google Transparency Report shows rise in data requests
One UK-based privacy advocacy group praised Google for releasing the data, but said it also served as a warning to individuals to be careful about the information they passed on to any online business.
"The information we hand over to companies like Google paints a detailed picture of who we are - from our political and religious views to our friendships, associations and locations," said Privacy International's head of international advocacy, Carly Nyst.
"This information therefore merits the highest degree of privacy and security, and should only be accessed by third parties under exceptional circumstances.
"Governments must stop treating the user data held by corporations as a treasure trove of information they can mine whenever they please, with little or no judicial authorisation."
