As the United Nations General Assembly begins its milestone 70th session, international digital security is high on the agenda. One starting point for discussion is likely to be the International Code of Conduct for Information Security (the “Code”). This analysis explores how the Code has developed over time, impetus behind the changes made, and the potential impact of the Code on international human rights law and its application. It is accompanied by an interactive comparison of the 2015 and 2011 versions of the Code.
In this paper presented at USENIX FOCI 2015 we use reverse engineering to provide a view into how keyword censorship operates on four popular social video platforms in China: YY, 9158, Sina Show, and GuaGua. We also find keyword surveillance capabilities on YY. Our findings show inconsistencies in the implementation of censorship and the keyword lists used to trigger censorship events between the platforms we analyzed. We reveal a range of targeted content including criticism of the government and collective action. These results provide evidence that there is no monolithic set of rules that govern how information controls are implemented in China.
