一种有效的共享多媒体内容作者身份保护方案
An Efficient Authorship Protection Scheme for Shared Multimedia Content
摘要：
如今，许多电子内容提供方（如Flickr和Google）向用户提供空间，以便在其云基础设施中发布其电子媒体（例如照片和视频），从而可以公开访问这些电子媒体。现有的提供商已经提供了包括其他信息（如关键字或所有者信息）的功能。尽管这些基础设施为用户提供了有用的功能，但发布内容的作者身份并没有受到诸如压缩等各种攻击的保护。在本文中，我们提出了一个强大的计划，使用数字不可见水印和散列保护数字内容的作者，并提供抵抗恶意操纵的多媒体内容。该计划是增强的算法称为MMBEC，这是一个扩展的既定计划MBEC，向更高的电阻。
英文摘要：
Many electronic content providers today like Flickr and Google, offer space to users to publish their electronic media (e.g. photos and videos) in their cloud infrastructures, so that they can be publicly accessed. Features like including other information, such as keywords or owner information into the digital material is already offered by existing providers. Despite the useful features made available to users by such infrastructures, the authorship of the published content is not protected against various attacks such as compression. In this paper we propose a robust scheme that uses digital invisible watermarking and hashing to protect the authorship of the digital content and provide resistance against malicious manipulation of multimedia content. The scheme is enhanced by an algorithm called MMBEC, that is an extension of an established scheme MBEC, towards higher resistance.
