Modifying the Data Stream: Deep Packet Inspection and Internet Censorship

Abstract

This paper will start by providing a short overview of DPI and it’s technical capabilities, before discussing the motivations of state and non-state actors using DPI. A short sample of various actors using DPI for censorship purposes will be provided and various scenarios related to censorship which are enabled by DPI will be introduced. Finally, some preliminary conclusions will be drawn and technical and institutional responses to DPI will be sketched.
