An anonymous reader writes "A security expert has panned Google's "real name" policy on Google+, claiming that the hard line will damage privacy. Sophos's Chester Wisniewski says that closing accounts where users have adopted false names erodes privacy on the social network. 'What they seemed to have missed is that the very foundation of privacy is identity. Simply knowing my postal code or birth date is meaningless without a name to associate it with. By requiring people to only use their real names, unless they just happen to be a celebrity, they have eliminated the ability for people to be private in any meaningful way.'"
