"The only basis for this processing seems to be consent. That means at a minimum that a pre-ticked box is not sufficient," he said.
This kind of data processing is also being discussed on a European level by the Article 29 Working Party, which is made up of data protection commissioners from each European Union member states, Hansen said. Her organization is part of the group, which she expects will discuss the issue further. She hopes that non-European users will also "question the behavior of companies that do not inform users properly and prefer opt-out over opt-in."
A Google spokesman could not immediately comment on Hansen's findings, but referred to a page where the company states that "Google does not know who you are when you use the My Location (beta) feature in Google Maps for mobile."
"The collection of location information is done only with the consent of users," the Google spokesman told Webwereld regarding the Dutch findings, adding that users can choose to switch this off at any time.
