Abstract
The Internet presents a problem for the protection of intellectual property. Those who create content must be adequately compensated for the use of their works. Rights agencies who monitor the use of these works exist in many jurisdictions. In the traditional broadcast environment this monitoring is a difficult task. With Internet Protocol Television (IPTV) and Next Generation Networks (NGN) this situation is further complicated.
In this work we focus on Digitally Watermarking next generation media broadcasts. We present a framework which provides the ability to monitor media broadcasts that also utilises a Public Key Infrastructure (PKI) and Digital Certificates. Furthermore, the concept of an independent monitoring agency, that would operate the framework and act as an arbiter, is introduced. We finally evaluate appropriate short signature schemes, suitable Watermarking algorithms and Watermark robustness.
