SBIR Phase II: Authentication of Mobile Video Recordings (MVRs) Based on Real-Time Hybrid Digital Watermarking

该小企业创新研究（SBIR）计划第二阶段项目旨在改进和商业化第一阶段开发的身份验证技术，使数字移动视频录制（MVR）系统能够部署。执法部门有一支庞大的巡逻车队，负责记录与平民接触的事件，每天收集MVR数据。由于运行电流模拟、非索引系统的成本惊人，因此对计算机化数字MVR技术的需求非常大。然而，由于数字媒体很容易被改变，它的部署受到法律认可的阻碍。身份验证为保障MVR内容的完整性提供了一种有效的手段，起到了关键的使能作用。为了利用这一新兴的数字MVR趋势，该公司提出了一项商业化战略，将创新技术包装在一个认证采集系统中，包括一个数字摄像机和一个用于实时视频水印、离线MPEG压缩和水印验证的软件套件。这种紧凑、低成本的采集系统利用现有的车载笔记本电脑进行处理和存储，专为满足下一代MVR系统提出的严格操作要求而设计。它与现有的It基础设施和计算机化的MVR管理系统无缝集成。MVR提供了一种有效的方式来保护执法机构、执法人员和他们所服务的公众。MVR认证为全国执法部门接受和部署节省成本的计算机化MVR技术提供了一种使能技术。它允许安全消除与维护MVR内容完整性相关的劳动密集型过程，因为水印是在飞行中完成的，并且没有MVR数据不受保护的时间窗口。随着配备水印认证技术的数字MVR系统的部署，与操作系统相关的成本将大大降低，节省下来的费用将被重新部署到其他执法工作中。在未来三年内，将建立一个全面的国家数字面部数据库，以支持国土安全。作为车内笔记本电脑的一个组成部分，这项技术将作为捕获数据提交给国家数据库的前线。

This Small Business Innovation Research (SBIR)Program Phase II project is aimed at the refinement and commercialization of the authentication technology developed during Phase I that enables the deployment of digital Mobile Video Recordings (MVR) system. A very large fleet of patrol vehicles operated by the law enforcement community that record events involving contact with civilians collects MVR data daily. Due to staggering costs associated with operating current analog, non-indexing system, there is an overwhelming needs for a computerized digital MVR technology. However, its deployment is hindered by legal acceptance, because digital medium can be easily altered. Authentication plays a critical enabling role by providing an effective means to safeguard the integrity of MVR content. To capitalize upon this emerging trend of digital MVR, the company proposes as a commercialization strategy to market the innovative technology in a package in an authenticated acquisition system, consisting of a digital video camera and a software suite for on-the-fly video watermarking, off-line MPEG compression and watermark verification. This compact and low-cost acquisition system leverages on existing in-car laptop for processing and storage, and is specifically designed to meet stringent operational requirements set forth by next generation MVR system. It integrates seamlessly with existing IT infrastructure and computerized MVR management systems. MVR has provided an effective way of protecting law enforcement agencies, their officers and the public they serve. The MVR authentication provides an enabling technology for the acceptance and deployment of cost-saving computerized MVR technology for the law enforcement community nationwide. It allows for safe elimination of the labor-intensive process associated with safeguarding the integrity of MVR content, because watermarking is done on the fly and there is no time window at which MVR data are ever unprotected. With the deployment of digital MVR system equipped with watermark authentication technology, the costs associated with operating the system will be greatly reduced allowing for the savings to be redeployed to other law enforcement endeavors. Within the next three years a comprehensive national digital facial database will be created to support Homeland Security. As an integral component of the in-car laptop, this technology will serve as the front line in capturing the data for submission to the national database.
