Switzerland's data protection commissioner on Friday announced that he was taking Google to court in a dispute over privacy concerns on the US Internet giant's "Street View" facility.

Federal Data Protection and Information Commissioner, Hanspeter Thuer, said in a statement that he was taking the case to the Federal Administrative Tribunal after Google had refused to apply the majority of measures he had recommended.

The Street View facility allows users to take a ground level panoramic view of some locations on Google Maps, based on still photographs taken by specially-equipped vehicles.

The Swiss data protection commissioner had repeatedly complained since the service was introduced in Switzerland this year that many images of faces and vehicle number plates were still easily identifiable and insufficiently blurred.

Thuer said on Friday that this was especially the case where the people concerned were shown around "sensitive locations, for example outside hospitals, prisons or schools."

He also raised concerns about the height of the car-top cameras Google uses to film locations, saying they afford a view over fences, hedges and walls "with the result that people see more on Street View than can been seen by a normal passer-by in the street."
