Cryptography and traitor-tracing watermarking are routinely used today to combat piracy of entertainment content. In this talk, we will explore how passive multimedia forensic analysis, recently proposed for content authentication, could be incorporated in the anti-piracy arsenal. After reviewing the piracy ecosystem, the talk will detail forensic techniques (i) to detect the type of piracy, (ii) to compensate for the effects of the piracy path e.g. prior to traitor tracing watermark detection, and (iii) to infer intrinsic parameters of the devices used to produce pirate samples.

This talk will be organized in three main parts. To begin with, I will review the ecosystem of the Entertainment industry, survey the different tools available to combat piracy and introduce the multimedia forensics workflow typically in use today. Next, I will focus on digital watermarking, a technology used to introduce imperceptible machine-readable markers in multimedia content. After briefly going through fundamentals, I will describe in more details the 2-step watermarking strategy adopted by Technicolor and discuss its pros and cons e.g.
