On the Security Enhancement of Multimedia Copyright Protection for E-Business

An important factor that slows down the growth of multimedia networked services is that authors, publishers and providers of multimedia data are reluctant to allow the distribution of their documents in a networked environment. This is due to the fact that it is easy to reproduce digital data in their exact original form, which encourages 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). Our experimental work shows that the watermarking algorithm based WPF robustness can enhance the security of watermarking.
