Privacy concerns have led the world's number one search provider to 'blur' the faces of those featured throughout it's mapping products.

Google announced this week that it would fuzz out the faces of people shown throughout it's mapping services, including Google's Street View product.

Privacy activists have rallied against the company since it began collecting ground-level images of streets and features across the United States and around the World.

Camera equipped 'Google-mobiles' have been spotted driving around US streets in a bid to capture ground-level photography for use by the company.

The service can be used to visit virtually streets across a number of countries.

Google said that it would now automatically blur the faces of those shown in it's street view products. The changes would also be applied to both new and current images within the Street View system.

The changes are expected to quell the fears of some privacy activists, however many still remain skeptical about the chances of identifying someone through their clothes and location.

"This effort has been a year in the making - working at Street View-scale is a tough challenge that required us to advance state-of-the-art automatic face detection," Google said in it's blog.

Although the technology blurs a person's face, it does not blur their clothing or other identifying marks.
