Google got a rap on its knuckle again for it’s Streetview violation, it was fined 145,000 euros  by The Hamburg Commissioner for Data Protection and Freedom of Information a German regulator for collecting wireless network data by its Street View cars. The Hamburg Commissioner called the company’s acts “one of the most serious cases of violation of data protection” in German history.

Google’s cars from 2008 to 2010 captured the data, including contents of e-mails, passwords, photos and chat protocols, Hamburg data regulator Johannes Caspar said in an e- mailed statement today. He had reopened the probe after prosecutors dropped a related criminal case last year.

“In my view, this is one of the biggest data protection rules violations known,” said Caspar. Google’s “internal control mechanisms must have severely failed.”
