Cory Doctorow is a web celebrity, so I'm sure his name is well know to you (otherwise: don't be ashamed and take a quick view to wikipedia). He calls himself in the first place a science fiction novelist. His novels are simultaneously released on paper as books you can buy on the book shop and on the Internet under Creative Commons licenses that encourage their re-use and sharing, a move that increases his sales by enlisting his readers to help promote his work. All information about his books and much more, you can easily find on his website.
But my guess is that Cory is better know as blogger and technology activist. He is the co-editor of the popular weblog Boing Boing, and a contributor to The Guardian, the New York Times, Publishers Weekly, Wired, and many other newspapers, magazines and websites. He was formerly Director of European Affairs for the Electronic Frontier Foundation, a non-profit civil liberties group that defends freedom in technology law, policy, standards and treaties.
It was as activist that Cory was invited at the annual conference of the German “Chaos Computer Club” (CCC) to give a lecture. It was titled “The coming war on general computation: the copyright war was just the beginning”:
The same CCC came in the news in October 2011 by publishing proofs that the German state administration used special developed malware to spy on its own citizens. (see here the original document of the CCC in German language and here and here two blogposts the organization made about it in English language). The German company DigiTask admitted later it sold this spyware to public authorities in Germany. The same company also confirmed that similar software has been sold to state and federal governments in Austria, Switzerland and the Netherlands (for more information see this article on the dw-world.de site).
