Abstract

In this paper we propose to use a secret key in feature domain. The secret key will be implemented using wavelet parameterization filters (WPF). This will improve the security of digital watermarking schemes operating in feature domain. The paper implements WPF into feature domain algorithm done by Kutter. Results show improvement of watermarking security of the feature domain algorithm using WPF without affecting the robustness and the invisibility of the feature domain algorithm.
