Security Enhancement of Multimedia Copyright Protection

The ease of reproducing digital data in their exact original form is likely to encourage copyright violation, data misappropriation and abuse. Watermarking security enhancement is highly required for multimedia copyright applications. This work enhances the security of watermarking algorithm without affecting the robustness of the watermark by implementing the wavelet filter parameterization (WPF). The experimental results show that the watermarking algorithm based WPF robustness can enhance the security of watermarking.
