"This study, which covers 121 UNESCO Member States, represents a global benchmarking of journalistic source protection in the Digital Age. It focuses on developments during the period 2007-2015. The legal frameworks that support protection of journalistic sources, at international, regional and country levels, are under significant strain in 2015. They are increasingly at risk of erosion, restriction and compromise - a development that is seen to represent a direct challenge to the established universal human rights of freedom of expression and privacy, and one that especially may constitute a threat to the sustainability of investigative journalism. In many of the countries examined in this Study, it was found that legal source protection frameworks are being actually or potentially: overridden by national security and anti-terrorism legislation; undercut by surveillance – both mass and targeted; jeopardised by mandatory data retention policies and pressure applied to third party intermediaries - like ISPs, telcos, search engines, social media platforms - to release data which risks exposing sources; outdated when it comes to regulating the collection and use of digital data, such as whether information recorded without consent is admissible in a court case against either a journalist or a source; and whether digitally stored material gathered by journalistic actors is covered by existing source protection laws."
