Google paid more than $1 million to Italy after a regulator found the company's Street View cars violated citizens' privacy by taking photos without their knowledge and permission.

The cars weren't marked well enough for people to realize and decide whether they wanted to be photographed, according to a government statement. In addition to the fine, Google had to begin marking its vehicles with signs or stickers, as well as posting its planned locations three days before shooting photos.

Google has faced fines in multiple European locations, including France. In that case, the American company had to pay a fine of more than $200,000 for privacy violations and was mandated to post that it had been fined on its French homepage.
