CNIL fines Google over Street View data collection (2011)
Google's Street View cars collected payload data from unencrypted home Wi-Fi networks across Europe. France's data protection authority, the CNIL, found the company had gathered personal content without informing users and fined it €100,000.
Google was ordered to stop the collection and delete the data in France within a set period.
The case established that data picked up incidentally from devices still requires a legal basis, a principle regulators have cited since.
Both cases turn on data a company could read from a device or network without the user specifically agreeing to that use.
