Abstract
Digital watermarking techniques enable digital-content owners to protect their property rights by embedding right-related messages into the host content before delivery. With the rapid growth of E-commerce, digital-content broadcasting has become the main stream of product delivering, which makes watermark embedding a must for protecting the owner''s property rights. In such a large service system, security, computational efficiency, and communicational overhead are the most challenging issues to service providers. In other words, there is an urgent need for developing robust and efficient watermark schemes for securing a digital content delivering system. In this paper, a novel secure client side watermarking scheme is proposed. We illustrate the reasons why a traditional watermarking scheme may not suit for a large digital-content broadcasting service and the ways how to fix the associated problems, in the proposed approach. Since the newly proposed scheme can support both visible and invisible watermarks, it is applicable to Cloud-based digital-content broadcasting services, such as Bookstores in Amazon and Google, iTunes in Apple, and Streaming Media in Netflix.
