Hi Lib Tech

The Citizen Lab published a new research paper on URL filtering and censorship, 
which presents an initial methodology for identifying and confirming the use of 
URL filtering products around the world. We leverage the fact that many of these 
products accept user-submitted sites for blocking to confirm that a specific URL 
filtering product is being used for censorship. Using this method, the paper 
confirms the use of McAfee SmartFilter in Saudi Arabia and the United Arab 
Emirates (UAE) and Netsweeper in Qatar, the UAE, and Yemen. The results show 
that these products are being used to block a range of content, including 
oppositional political speech, religious discussion and gay and lesbian 
material, and speech generally protected by international human rights norms. 
The paper is authored by Citizen Lab's Ronald J. Deibert, Masashi 
Crete-Nishihata, Jakub Dalek, Bennett Haselton, Helmi Noman, and Adam Senft, 
and Phillipa Gill of the Department of Computer Science, Stony Brook 
University.
