U.N. Report Calls Encryption Necessary for Free Expression

A new report from the United Nation's Office of the High Commissioner for Human Rights says digital security and privacy are essential to maintaining freedom of opinion and expression around the world -- and warns that efforts to weaken security tools in some countries may undermine it everywhere. The report written by special rapporteur David Kaye says that encryption -- the process of digitally scrambling information so that only authorized persons can access it -- and anonymity tools "provide the privacy and security necessary for the exercise of the right to freedom of opinion and expression in the digital age."
