Watermarking in online media e-business

The need of copyright protection has become a detachable requirement for online media e-business as online multimedia businesses and enabling technologies become viable in recent years. Watermarking enables copyright protection in e-business but it also slows down the packaging process for delivery. The requirement of instant delivery is a prime requirement for online business. In the literature, extensive research on water-marking performance has been emphasized on imperceptibility and robustness but not the efficiency factor for online e-business, for example processing time and storage requirement that are crucial to the success of online e-business. In this paper, we investigate four watermarking schemes derived from one-bit watermarking, multiple-bit water-marking and their combinations in order to identify viable watermarking scheme that can meet the requirements of online e-business. The performance of these schemes in terms of preparation time, delivery time and storage requirement were measured and reported in this paper. Our analysis proves that the watermarking schemes with multiple-bit watermarking can ensure instant delivery with a penalty of some extra storage requirements.
