Swiss officials said Friday that they had sued Google to try to require it to tighten privacy safeguards on its Street View online service. It is the latest of a series of European objections to the company’s handling of personal information.

The Swiss data protection authority said it had filed a complaint with the Federal Administrative Court after Google balked at its demand for additional measures to make obscure the images of people who appear in Street View, particularly in areas around hospitals, schools and prisons.

Street View provides ground-level panoramas of streets across the United States, Europe and other regions, searchable via Google’s mapping service. Google compiles the scenes with camera-equipped cars.

Google already blurs the faces and license plates that appear in Street View. Users of the service can also request that certain images, like their homes, be removed or blurred.
