The French data privacy regulator has fined Google €100,000 for the collection of personal WiFi activity while it recorded data for its Street View service.

According to Fudzilla, this is one of the steepest fines that the National Commission for Information Freedom (CNIL) has issued since it obtained the power to impose financial sanctions in 2004. The regulator said this was an ‘unfair collection' of information under French law and Google had received economic benefits from the data.

The French commissioner was one of many to publicly criticise Google over privacy issues related to Google Buzz last year and now follows the UK, Australia and Spain in conducting a separate investigation of Street View. In the UK, the Information Commissioner's Office (ICO) found Google to be in breach of the Data Protection Act but said it had no intention to issue a fine.
