30 Sep Google ordered by German commissioner to stop data profiling
A local data commissioner in Germany said this week that Google’s extensive combining of the data it has on individual users is abusive and must be stopped.
That administrative order is bringing to a head the question of whether U.S.-born, ad-driven Web services like Gmail, YouTube and Facebook can peacefully co-exist with a Europe that is enormously sensitive about possible incursions on personal privacy.
“According to the views of the data protection authority,” reads a news release from the Hamburg Commissioner of Data Protection and Freedom of Information, “the ongoing practice of user profiling affects the privacy of Google users far beyond the admissible degree.”
At particular issue is how Google blends a user’s data collected across its various services into one unifying profile. “In short, we’ll treat you as a single user across all our products,” the company said in announcing the controversial opt-out policy in 2012. Google argues that the way data slips between its products leads to more useful tools, making it “easy for you to read a memo from Google Docs right in your Gmail, or add someone from your Gmail contacts to a meeting in Google Calendar.”
Critics say Google’s driving interest is in using that data to sell targeted advertising.
The danger, says Johannes Caspar, the Hamburg data commissioner, is something sometimes called “the mosaic effect” — the fact that data in combination can reveal more than standalone nuggets of information. Caspar warned that everything from local data to search engine requests can be used to determine a user’s travels, interests, financial standing, social status and sexual orientation.
