An anonymous blog is a blog without any acknowledged author or contributor. Anonymous bloggers may achieve anonymity through the simple use of a pseudonym, or through more sophisticated techniques such as layered encryption routing, manipulation of post dates, or posting only from publicly accessible computers. Motivations for posting anonymously include a desire for privacy or fear of retribution by an employer (e.g., in whistleblower cases), a government (in countries that monitor or censor online communication), or another group. Deanonymizing techniques Fundamentally, deanonymization can be divided into two categories: Social correlation compares known details about a person's life with the contents of an anonymous blog to look for similarities. If the author does not attempt to conceal their identity, social correlation is a very straightforward procedure: a simple correlation between the "anonymous" blogger's name, profession, lifestyle, etc., and the known person. Even if an author generally attempts to conceal their identity (by not providing their name, location, etc.), the blog can be deanonymized by correlating seemingly innocuous, general details. Technical identification determines the author's identity through the blog's technical details. In extreme cases, technical identification entails looking at the server logs, the Internet provider logs, and payment information associated with the domain name. These techniques may be used together. The order of techniques employed typically escalates from the social correlation techniques, which do not require the compliance of any outside authorities (e.g., Internet providers, server providers, etc.), to more technical identification. Types Just as a blog can be on any subject, so can an anonymous blog. Most fall into the following major categories: Political: A commentary on the political situation within a country, where being open may risk prosecution. Anonymous blogging can also add power to a political debate, such as in 2008 when blogger Eduwonkette, later revealed as Columbia University sociology graduate student Jennifer Jennings, successfully questioned New York Mayor Michael Bloomberg's takeover of New York schools. Revolutionary and counter-revolutionary: These can either be inspiring activity or counter activity, often against a violent state apparatus. For example, Salam Pax, the Baghdad blogger, wrote for The Guardian newspaper under a pseudonym that he could shed only when Saddam Hussein no longer ruled in Iraq. Similar bloggers appeared during the Arab Spring. Dissident: Dissident blogs may document life under an oppressive or secretive regime, while not actively promoting or inspiring revolutionary or counter-revolutionary action.
