I worry that increasingly far-reaching and burdensome copyright laws, when combined with the analysis techniques of Deep Packet Inspection (DPI), will lead to pervasive chilling of speech. I see this as having real issues for both the creation and development of contemporary culture, which depends on mixing the past into new creations (with ‘the past’ increasingly copy-written), and for the opportunities to use rich media environments such as the Internet to create and distribute political statements. Copyright isn’t just an issue for musicians and artists; it’s an issue for anyone who is or who wants to engage in digital self-expression in media-creative ways.
Given that my earlier post about this relationship between DPI and freedom of expression may have seemed overly paranoid, I thought that I should substantiate it a bit by turning to a DPI vendor’s white paper on copyright. In one of their most recent white papers, ipoque talks about “Copyright Protection in the Internet“. One of the great things about this white paper is how the author(s) have divided their analysis; they identify different methods of limiting or stopping infringement theoretically (i.e. can a technology do this?) and then provide a ‘reality check’ (i.e. can this practically be implemented without gross rights violations or technical nightmares), and end each analysis with a conclusion that sums up ipoque’s official position on the method in question. I want to focus on detecting infringing files, rather than on preventing such transfers of those file, on the basis that it is the former that really depends on DPI to be effective.
