Google has admitted it has been collecting data from unsecured Wi-Fi networks for three years. The error came to light after German data protection authority audited the data collected by Street View cars for use in location-based products such as Google Maps for mobile. Google said the error came after a piece of code written in 2006 was included in the software used by the cars. The search engine also confirmed that it did not collect any data from secure password-protected Wi-FI networks. Google is now asking a third-party to review the software and confirm the data has been deleted.”]
