Abstract

The need for 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 watermarking 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. We investigate four watermarking schemes derived from one-bit watermarking, multiple-bit watermarking and their combinations in order to identify a 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 are measured and reported. Our analysis proves that the watermarking schemes with multiple-bit watermarking can ensure instant delivery with a penalty of some extra storage requirements.

在线媒体电子商务中的水印

近年来，随着网上多媒体业务和使能技术变得可行，保护版权的需要已成为网上媒体电子商务的一项不可分割的要求。水印可以在电子商务中保护版权，但它也减慢了交付的包装过程。即时交付的需求是在线业务的主要需求。在文献中，对水印性能的广泛研究强调的是不可感知性和鲁棒性，而不是在线电子商务的效率因素，例如对在线电子商务成功至关重要的处理时间和存储要求。本文研究了由一比特水印、多比特水印及其组合衍生而来的四种水印方案，以确定一种能够满足在线电子商务要求的可行的水印方案。测量并报告了这些方案在准备时间、交货时间和存储要求方面的表现。我们的分析证明了采用多比特水印的水印方案可以保证即时传输，但会损失一些额外的存储需求。
