theodp writes "'It's important to use your common name,' Google explains in its Google+ ground rules, 'so that the people you want to connect with can find you.' Using a 'secondary online identity,' the search giant adds, is a big Google+ no-no. 'There are lots of places where you can be anonymous online,' Betanews' Joe Wilcox notes. 'Google+ isn't one of them.' Got it. But if online anonymity is so evil, then what's the deal with Google's newly-awarded patent for Social Computing Personas for Protecting Identity in Online Social Interactions? 'When users reveal their identities on the internet,' Google explained to the USPTO in its patent application, 'it leaves them more vulnerable to stalking, identity theft and harassment.' So what's Google's solution? Providing anonymity to social networking users via an 'alter ego' and/or 'anonymous identity.' So does Google now believe that there's a genuine 'risk of disclosing a user's real identity'? Or is this just a case of Google's left hand not knowing what its right hand is patenting?"
