""It is already known that some companies, such as Google and Facebook, track users online and know their identities," said Arvind Narayanan, an assistant professor of computer science at Princeton and one of the authors of the research article. But those companies, which consumers choose to create accounts with, disclose their tracking. The new research shows that anyone with access to browsing histories -- a great number of companies and organizations -- can identify many users by analyzing public information from social media accounts, Narayanan said."
