Abstract

Although it is clear that security is an important issue in digital watermarking applications,the main concerns addressed by the current literature are robustness, capacity and imperceptibility. The inadequacy of the prevailing design paradigm in tackling security issues is mainly due to an incomplete assessment of the threat model. The goal of this paper is to take a detailed and rigorous look at the threat model for a variety of watermarking applications. In this extended abstract, we outline the security requirements for a few common watermarking applications and explore in more detail the threat model for a specific application that involves establishing ownership of multimedia content.
