The European Union's Article 29 Working Party regulator group said on Thursday that it would put out a non-binding opinion that would set the direction for location data on smartphones and other devices. The statement would call on companies to assume location was personal information and get permission, avoid tying location to a person, and purge the information after a certain amount of time. It could serve as a possible guideline, however, for future action by the European Commission or individual countries that would make location privacy a requirement.
