A Provable Watermark-Based Copyright Protection Scheme

Abstract

Watermark-based copyright protection techniques have been investigated for more than two decades in the signal processing and the digital rights management communities. Most efforts have been devoted on hiding the watermark and increasing the robustness of the embedded watermark under common signal processing operations and geometric transformations. In this paper, we build our scheme based on these previous well developed signal processing techniques but focus on how to employ unpredictable signature-seeded pseudo random bit sequence to make the false negative watermark detection rate computationally negligible. The ultimate goal is to resolve the ownership dispute of an exhibited digital media under adversarial watermark removal attacks.
